    MULTIFILAMENT YARN CONSTRUCTION, MEMBER UNDERSTANDING THE REFERRED CONSTRUCTION, AS WELL AS USES OF THE SAME
    TECHNICAL FIELD OF THE INVENTION [001] The invention relates to a multifilament yarn construction, such as a rope, a cable or a suture, the construction comprising a plurality of multifilament yarns. More particularly, the invention relates to a multifilament yarn construction with yarns arranged in a core part and a braided covering part. In addition, the invention relates to uses of such multifilament yarn constructions.
    BACKGROUND OF THE INVENTION [002] Multi-filament yarn / sheath constructions are known. An example of such a construction is US coating of
    2008 / 0009903A1. Multifilament core / yarn constructions are normally used to obtain a construction with less flexion fatigue. In addition, multifilament core / coating constructions typically behave like plastic under bending without much if there is elastic deformation.
    Bending plasticity is typically associated with local bending stresses. In other words, the force against bending deformation is very small.
    [003] When the yarn is a thermoplastic yarn, the stiffness of multifilament yarn constructions can be increased by heat treating the construction to a level where the yarns at least partially fuse to form a monofilament-like coating such as example, as described in EP 1 771 213. However,
    Petition 870180061009, of 07/16/2018, p. 6/58
    2/35 monofilaments and monofilament constructions typically behave with elastic over flexion at smaller flexion angles, without leaving much - if any plastic deformation after removing the flexing force. For large bends in monofilament and sharp angle monofilament constructions, they can deform plastically, however, such plastic deformation will introduce considerably damage to the monofilament construction.
    [004] Other multifilament core / sheet constructions are disclosed in US 3,968,725 (Holzhauer), EP 1 293 218 (Grafton et al.) AND WO 2009/142766.
    OBJECTIVES OF THE INVENTION [005] It is an objective of the present invention to provide a multifilament yarn construction, where the construction has improved properties.
    [006] It is another objective of the present invention to provide uses of the improved multifilament yarn construction.
    [007] The improvement can be, for example, increased rigidity, compaction and / or handling of a construction according to the first aspect of the invention and wire constructions comprising the segment.
    DESCRIPTION OF THE INVENTION [008] The purpose of the invention is achieved through a multifilament yarn construction that the construction comprises a core part and a covering part.
    [009] The core part comprises a plurality of core filaments. The core filaments can be
    Petition 870180061009, of 07/16/2018, p. 7/58
    3/35 arranged in one or more multifilament yarns or be a set of monofilaments. The core filaments can advantageously be arranged in parallel or substantially in parallel, which allows more efficient use of the strength of the core filaments. If the core consists of a multifilament yarn, it is preferred that the yarn is twisted with a torsion level of less than 100 turns per meter. If the core consists of more than one multifilament yarn, such as at least 3 multifilament yarns, or more than one monofilament, it is preferred that the multifilament yarns or monofilaments are arranged in a braided, folded, twisted or braided construction . Most preferred is a braided core construction, such as one on one (see Figure 2.) of, for example, four, six, eight, twelve or sixteen threads or monofilaments. It has been found to be advantageous to use a braid of eight or 16 strands of multifilament in the core as this has provided a very stable construction. In another embodiment, it is preferred to have a core of one or more multifilament yarns arranged substantially parallel to the length of the construction.
    [0010] The coating part comprises a plurality of coating filaments. The lining part is braided to the core part. The coating filaments can be arranged in multifilament threads or the filaments can be coating monofilaments, so that the coating is braided from multifilament threads and / or monofilament threads. It is preferable that the coating filaments are made up of multifilament yarns, as
    Petition 870180061009, of 07/16/2018, p. 8/58
    4/35 to allow easy fabrication by and accessible and readily available starting material. The braid can be, for example, one on one (see Figure 2), two on one (see
    Figure 3) or three over one (not shown) of, for example, four, six, eight, twelve or sixteen threads or monofilaments.
    It has been found to be highly advantageous to use a braid of eight or 16 strands of multifilaments in a diamond braid one on one like that allowed for a high point level and the best connection between the strands of the coating with a high braiding angle and factor high filling and it has been found to lead to harder multifilament yarn constructions according to the invention.
    [0011] The coating part of the multifilament yarn construction according to the first aspect of the present invention is between 4-75% of the area of a cross section of the multifilament yarn construction. Cross-sectional area here means the area in a plane orthogonal to the length of the multifilament yarn construction. In addition, the coating part's braiding angle is at least 30 °. The braiding angle is the angle between the coating filaments and a plane parallel to the length of the multifilament yarn construction according to the invention. The braiding angle is calculated as described below. A sketch in US 3,968,725 (Holzhauer) reveals a construction with a spacing of 30 per foot (see the data on the sheet in an experimental part). This corresponds to a braiding angle of about 30 ° for a diameter of 0.3 inches (7.6 = mm), which is therefore
    Petition 870180061009, of 07/16/2018, p. 9/58
    5/35 functionally away from the braiding angles claimed in the present invention, which also explains why no surprising stiffness was revealed by Holzhauer.
    [0012] A further embodiment of the invention relates to a multifilament yarn construction comprising a core part and a covering part. The coating part comprises a plurality of core filaments, and the coating part comprising a plurality of coating filaments. The covering part is between 4-40% of the area of a cross-section of the multifilament yarn construction, and the covering part is braided over the core part. In addition, the ratio of the cross-sectional area of the multifilament yarn construction to the theoretical cross-sectional area of the multifilament yarn construction is a maximum of 1.5, and the width of the multifilament yarn construction is 0, 2 to 5 mm. This aspect of the present invention provides a very compact construction of multifilament yarns.
    [0013] A further embodiment of the invention relates to a multifilament yarn construction comprising a core part and a covering part. The coating part comprises a plurality of core filaments, and the coating part comprising a plurality of coating filaments. The covering part is between 4-75% of the area of a cross section of the multifilament yarn construction, and the covering part is braided over the core part. In addition, the strain strain of
    Petition 870180061009, of 07/16/2018, p. 10/58
    6/35 flexion, 05%, of the multifilament yarn construction according to the second aspect of the present invention is at least 3 N / mm 2 . The flexural strain strain, 05%, is the apparent stress according to the assumption of the elastic beam theory as assumed in the ASTM D 7 90-07 standard (see below) for the construction of multifilament yarn in 5% strain . The width of the multifilament yarn construction according to this aspect of the invention is between 0.2 and 5 mm. This embodiment of the present invention, optionally, has a coating part braiding angle of at least 30 °.
    [0014] Traditional multifilament yarn constructions are flexible as multiple filaments are allowed to shift in relation to each other when bending. Therefore, it is highly surprising that the construction of multifilament yarn according to the invention is tough and behaves substantially like a solid bar when it comes to bending behavior. This is seen as a tendency to be tough and - to bend - hard in the new shape. This is a highly advantageous property as it allows, for example, to link the construction of multifilament yarn around an obstruction, without the need to carry the construction by the end. An example of this is in a medical procedure, in which the construction of the multifilament thread is used in a medical suture and the suture must be moved around a bone, with no space to guide the suture thread. Another example is when the wire construction has to follow a guide tube with a significantly larger diameter than the multi-filament wire construction, where the wire construction
    Petition 870180061009, of 07/16/2018, p. 11/58
    7/35 multifilaments of the present invention reduces the risk of wire defect inside the guide tube.

    DETAILED DESCRIPTION [0026] In Figure 1 an example of a schematic cross section 30 of a core coat multifilament yarn construction is shown. The core part 10 comprises a plurality of core filaments (not shown), and the coating part 20 comprises a plurality of coating filaments (not shown). In one embodiment, the core part or the sheath part may be covered, for example, to increase the rigidity of the construction, introduce electrical insulation between the core and the sheath, or between the construction of multifilament yarn and the surrounding environment , or to introduce an active component, such as an antimicrobial agent, or a growth factor. The cover can be a cover, which does not penetrate substantially into the space between the filaments and / or the cover can be an impregnation cover, which can, for example, improve the rigidity of the multifilament yarn construction.
    [0027] Cross section here means a section orthogonal to the direction of the length of the wire construction.
    [0028] Yarn construction here means a combination of yarns arranged in a rope-like construction (such as a rope, a cable, a suture, a thread, a fishing line, etc.), a woven or non-woven textile construction, a network or a plot.
    [0029] In a highly preferred modality, the
    Petition 870180061009, of 07/16/2018, p. 13/58
    9/35 fill factor of the coating part is at least 7. The fill factor is an indicator of the proximity of the filament arrangement (usually in multifilament yarns) on the surface of the core part. Below is a specification on calculating and determining the fill factor, in the present case. It was found that a high filling factor tends to increase the rigidity of the multifilament yarn construction. Higher fill factors, such as a fill factor of at least 8 or 9 additionally reinforced the stiffness of the multifilament yarn construction and a particularly advantage was found in a fill factor of at least 10. In general, it was found that how much the greater the fill factor, the harder the construction of the multifilament yarn. The maximum fill factor is determined by the structural limitation and depends on a series of parameters, such as the braiding angle and the area ratio between the core part and a coating part and can be determined experimentally for the configuration of the individual multifilament yarn. However, as a general rule, the fill factor is typically (but not necessarily) below 20.
    [0030] In most cases, the cross section constructs multifilament yarn according to the substantially circular invention.
    This is particularly the case for multifilament yarn constructions according to the aspect of the invention relating to the high compaction mode. The cross-sectional area of the multifilament yarn construction is
    Petition 870180061009, of 07/16/2018, p. 14/58
    10/35 calculated from the average diameter measured with an ODAC 15XY laser by a dual axis measurement. The theoretical cross-sectional area is the area corresponding to the measured title of the multifilament yarn construction, assuming no porosity in the construction. Perfect compaction of the multifilament yarn in the construction corresponds to a ratio of A / A = 1, which means that, basically, the yarn is fully compacted and no air is trapped inside the construction. According to this aspect of the invention, the ratio, a / A, from the cross-sectional area of the multi-filament yarn construction, a, to the theoretical cross-sectional area of the multi-filament yarn construction, A, should be at most 1.5, however, it was found to be it is highly advantageous that a / A is at most 1.3, and more preferably, the ratio is at most 1.2, and even more preferably at most 1.1. This can be achieved through a combination of one or more of the braiding angles (preferably high braiding angles, as discussed elsewhere), fill factor (preferably high fill factors as discussed elsewhere), the choice of yarns (preferably high modulus fibers (with high longitudinal modulus) with relatively soft transversal modulus, such as centrifuged HPPE gel yarn) The highly compact multifilament yarn constructions are highly advantageous for applications where the low profile (diameter) of the yarn construction is important, as well as in medical applications involving minimal invasive techniques.
    [0031] A highly surprising feature
    Petition 870180061009, of 07/16/2018, p. 15/58
    11/35 of the multifilament yarn constructions of the present invention was that when repeatedly bent a decrease in the flexural strain stress was limited and the strength of the multifilament yarn construction was substantially unchanged. This combination of characteristics (high strength and stiffness, also after repeatedly flexing) has been required for medical applications for a long time. Therefore, a highly preferred embodiment of the multifilament yarn construction according to the invention has an exhausted bending strain strain, 05%, 5, of more than 45% of the bending strain strain, 05%, of the wire construction of multifilaments. Particularly preferred are multifilament yarn constructions where the exhausted bending strain strain, 05%, 5, is at least 55% of the bending strain strain, 05%, of the multifilament yarn construction.
    [0032] The core and coating filaments can be selected from a wide variety of natural and synthetic fibers, however, it is preferable that at least 50% by weight of a plurality of core filaments of the multifilament yarn construction and / or of at least 50% by weight of the coating filaments of the multifilament yarn construction are selected from the group consisting of synthetic fibers such as nylon, polypropylene, polyesters, polyethylene, aramides and polyamides. More preferably at least 90% by weight of a plurality of core filaments of the multifilament yarn construction and / or at least 90% by weight of the coating filaments of the multi-yarn construction
    Petition 870180061009, of 07/16/2018, p. 16/58
    12/35 multifilaments are selected from the group consisting of synthetic fibers such as polypropylene, nylon, polyesters, polyethylene, aramides and polyamides. Higher rigidity was found when the filaments were selected from high modulus filaments, such as filaments, with an e-modulus of at least 5 GPa and even better with an e-modulus of at least 9 GPa. In a preferred embodiment at least 90% by weight of a plurality of core filaments of the multifilament yarn construction and / or at least 90% by weight of the coating filaments of the multifilament yarn construction are therefore selected from the group consisting of polyethylene of high performance (HPPE) and high performance aramids.
    [0033] HPPE is understood here as high performance polyethylene, which is stranded polyethylene based with a Young modulus of at least 30 GPa. HPPE can, for example, be prepared by a process of melting the spinning (as, for example, example, disclosed in EP1445356), by the solid state process (for example, as disclosed in EP1627719) or by gel spinning (as for example described in WO 2005/066401). A particularly preferred type of HPPE is ultra high molecular weight polyethylene centrifuged gel (UHMWPE), where UHMWPE has an intrinsic (IV) viscosity as measured in decalin solution at 135 ° C, at least 5 dl / g, preferably at least 10 dl / g, more preferably at least 15 dl / g, more preferably at least 21 dl / g. Preferably, IV is at most 40 dl / g, more preferably at most 30 dl / g, even more preferably at most 25 dl / g. Gel
    Petition 870180061009, of 07/16/2018, p. 17/58
    13/35 UHMWPE centrifuged typically has a Young's modulus of at least 50 GPa.
    [0034] Particularly advantageous if HPPE, which is stretched polyethylene. The most preferred HPPE was UHMWPE centrifuged gel, which combines extremely high toughness, modulus and abrasion strength. Thus, in a preferred embodiment of the invention, at least 90% by weight of a plurality of core filaments of the multifilament yarn construction and / or at least 90% by weight of the coating filaments of the multifilament yarn construction are UHMWPE gel centrifuged.
    [0035] In one embodiment, the core part and / or the covering part comprise an electrically or optically conductive component, so that the construction of multifilament wire can conduct electricity (for example, electrical signals or electrical energy) or light (for example, optical signals or energy, such as a laser beam). In this embodiment, it is highly preferred that at least one of the core filaments or coating filaments is high-performance polyethylene (HPPE), as HPPE combines high strength and abrasion strength and thus reduces the risk that the component will electrically or optically conductive will be damaged during use.
    [0036] The ratio between the area of the core part and the coating part can vary considerably. In general, it was also observed that the greater the fraction of the cross-sectional area, which is responsible for, in the covering part, the greater the rigidity of the multifilament yarn construction, when the filaments of the core part and
    Petition 870180061009, of 07/16/2018, p. 18/58
    14/35 the coating part consists of the same material. Thus, in a preferred embodiment, the core part 10 is at least 25% of the cross-sectional area 30 of the multifilament yarn construction 4a, more preferably, the core part is at least 30% of the cross-sectional area 30 of the multifilament yarn construction 4a, and when the strength of the multifilament yarn construction is particularly important, it is preferable that the core part is at least 35% of the cross-sectional area 30 of the multifilament yarn construction. In a preferred embodiment of multifilament yarn construction with a particularly high strength, the core part comprises a large part of the cross section, such as the core part being more than 96% of the cross section area 30 of the yarn construction multifilaments 4a. For highly rigid multifilament yarn constructions, it has been found to be advantageous that the core part represents a maximum of 50% of the cross-sectional area 30 of the multifilament yarn construction 4a, and more preferably the core part represents a maximum of 4 0% cross-sectional area 30 of the multifilament yarn construction 4a. By very high rigidity multifilament yarn constructions, the core part represents a maximum of 35% of the cross-sectional area 30 of the multifilament yarn construction 4a, such as, for example, a maximum of 30% of the cross-sectional area 30 of the construction of multifilament yarn 4a.
    [0037] It was also observed that the greater the fraction of the cross-sectional area, which is responsible for, in the
    Petition 870180061009, of 07/16/2018, p. 19/58
    15/35 core part, the greatest strength when the filaments of the core part and coating part consist of the same material. In another embodiment, the multifilament yarn construction 4a according to the invention, the core part was at least 80% of the cross-sectional area 30, of the multifilament yarn construction 4a, and more preferably at least 85% of the cross-sectional area. cross-sectional area 30 of the multifilament yarn construction 4a. For building higher strength multifilament yarn according to the invention, it has been found that it is advantageous that the core represents at least 90% of the cross-sectional area 30 of the multifilament yarn construction 4a, such as at least 93% area cross section 30 of the multifilament yarn construction 4a. In order to ensure a certain stiffness for the construction of higher strength multifilament yarns according to the invention, it was found that the core part should preferably represent more than 96% of the cross-sectional area 30 of the yarn construction of multifilament yarn 4a and, more preferably, at most 94% of the cross-sectional area 30 of the multifilament yarn construction 4a.
    [0038] The diameter of the multifilament yarn construction according to the invention may vary depending on the application of the construction. For most applications, a width of between 0.2 mm to 5 mm is suitable. Width here means the largest cross-sectional dimension of the multifilament yarn construction orthogonal to the direction of the length of the multifilament yarn construction. It appears that for larger widths, the effect of construction on the flexural strain stress is
    Petition 870180061009, of 07/16/2018, p. 20/58
    16/35 reduced, and the simple diameter of the construction appears to have a greater influence on the flexural behavior of the multi-stranded wire construction. This also explains why no surprising stiffness was observed in US 3,968,725 (Holzhauer) for a construction with a diameter of 0.3 inches (7.6 = mm).
    [0039] For applications within the sport, such as thin ropes for yachting and fishing lines, and medical applications, such as sutures, cables and actuators, width from 0.3 mm to 4 mm is suitable and preferably widths of 0.4 mm up to 3mm provide the greatest effect for applications such as medical cables and sutures.
    [0040] The tensile strength of the multi-filament yarn construction according to the invention can depend considerably on the tensile strength of the filaments used for the core and sheath filaments. It is preferable - but not necessary to achieve any flexural strain strain - that the tensile strength of the multi-strand yarn construction is at least 10 cN / dtex and, more preferably, at least 15 cN / dtex. This is possible, for example, for the construction of multi-strand yarn comprising HPPE optionally in combination with other types of filaments, such as polyester or aramides. The most preferred are the multi-strand wire constructions with a tensile strength of at least 20 cN / dtex, since this multi-strand construction allows a very high force, with a very small construction width, which is highly requested, for example, in medical applications where minimal invasive techniques continue to push the limit of
    Petition 870180061009, of 07/16/2018, p. 21/58
    17/35 required material performance.
    [0041] Highly surprisingly it has been found that for the construction of multifilament yarn according to the invention, the rigidity of the construction increases when the braiding angle is increased. This is in contrast to the typical situation for fibrous materials, where the alignment of the fibers in the length direction tends to increase the stiffness and alignment of the fibers away from the length direction tends to decrease the stiffness.
    Thus, for a preferred embodiment of the invention the braiding angle of the coating part of the multifilament yarn construction 4a is at least 33 ° and more preferably, the braiding angle of the coating part is at least 35 ° . In another embodiment, the braiding angle of the lining part of the multifilament yarn construction 4a is at least 40 °, and preferably, the braiding angle of the lining part of the multifilament yarn construction (4a) is at least minus 45 ° or better still at least 55 °. Furthermore, it was found that the most rigid multifilament yarn constructions had a braiding angle of the coating part of multifilament yarn construction 4a of at least 60 °.
    [0043] It was also found that, for extremely high braiding angles, construction tends to be complex and time-consuming to prepare. In another embodiment, the construction of multifilament yarn 4a according to the invention therefore has a braiding angle of the covering part of at most 75 °, and preferably the braiding angle is at most 70 °. More
    Petition 870180061009, of 07/16/2018, p. 22/58
    18/35, preferably, the braiding angle of the coating part is at most 66 °.
    [0044] The multifilament yarn constructions 4a according to the invention are all hard, but the variable stiffness depends on the construction itself, as well as the choice of filament material for the core part, and - in particular - the part of wrapper. In one embodiment of the invention, the flexural strain strain, 05%, of the multifilament yarn construction 4a is at least 3 N / mm 2 , preferably the flexural strain strain, 05%, of the wire construction of multifilaments 4a is at least 5 N / mm 2 . For the most preferred embodiments, the flexural strain strain, 05%, of the multifilament yarn construction 4a is at least 7 N / mm 2 , and more preferably the flexural strain strain, 05%, of the construction of multifilament yarn 4a is at least 15 N / mm 2 . The best combination of yields of construction parameters exhibited a flexural strain strain, 05%, of the multifilament yarn construction 4a of at least 20 N / mm 2 .
    [0045] As the very high stiffness is disadvantageous in some applications, in one embodiment, the flexural strain strain, 05%, 4a of the multifilament yarn construction can optionally be less than 50 N / mm 2 , such as less than 30 N / mm 2 .
    [0046] Another aspect of the present invention concerns a member 2 comprising a multifilament yarn construction 4a according to the first aspect of the invention. In one embodiment, member 2 is a sport device, such as a fishing line, yachting ropes or
    Petition 870180061009, of 07/16/2018, p. 23/58
    19/35 a kite line. Such members tend to become entangled during use and, surprisingly, it has been found that if the member comprises the construction of multifilament yarn according to the invention, the tendency to become entangled is reduced and the ability to separate the member is increased . The same is observed for ropes and rope constructions, as well as nets, such as fishing nets and cargo nets. In another modality, the member is an anti-ballistic article.
    [0047] In a particularly preferred embodiment of the invention, the limb is a medical implant or a medical repair product, such as a wire, cable or mesh, where the combination of stiffness and stiffness and strength retention capacity, then repeatedly flexing is very much in demand.
    For the members to be used in medical applications, it is particularly advantageous to use the multifilament yarn constructions comprising HPPE filaments, as this allows for even greater very high strength and, consequently, allows for the greater miniaturization required of minimal invasive techniques. Another aspect of the invention, therefore, concerns the use of a multifilament yarn construction 4a according to the first aspect of the invention, or of a member 2 according to the second aspect of the present invention in a medical repair product. This use is particularly advantageous when the medical repair product is a suture, cable, or mesh.
    [0048] Due to the ability of the construction of multifilament yarn to reduce entanglement and improve the disentanglement of a limb that comprises the construction of
    Petition 870180061009, of 07/16/2018, p. 24/58
    20/35 multifilament yarn, another aspect of the present invention concerns the use of a segment 4a according to the first aspect of the invention, or of a member according to the second aspect of the present invention to reduce the formation of knots or to reduce node strength. It is highly surprising that the construction has the following highly useful capabilities. It could be theorized, without being limited to them, that these capacities are related to the stiffness of multifilament yarn constructions compared to other yarn constructions of similar dimensions.
    [0049] A particular type of limb 2 according to the invention both comprises a multifilament yarn construction 4a according to the invention, and an additional multifilament yarn construction 4b, wherein the additional multifilament yarn construction 4b is different from construction of multifilament yarn 4a according to the invention. This is illustrated in Figure 8. In particular, it has been found to be advantageous when the additional multifilament yarn construction 4b is not a multifilament yarn construction according to the invention. This in particular allows arrangements of the rigid multifilament wire constructions according to the invention, in connection with a more flexible construction, so that the rigid part can be used to position the member and the flexible part can be used to tie the construction of multifilament yarn, once in place. Therefore, it is particularly advantageous when the multifilament yarn construction 4a according to the invention is arranged near an end of the member (2) and even more
    Petition 870180061009, of 07/16/2018, p. 25/58
    21/35 preferably when the multifilament yarn construction 4a according to the invention is provided close to both ends of the member 2 with at least one additional multifilament yarn construction 4b disposed between the multifilament yarn constructions 4a. This is illustrated in Figure 9. It should be noted that Figure 8 and Figure 9 are not drawn to scale, and that the length of the sections can vary considerably, so that point 4a can be very short compared to section 4b or vice versa.
    Determination of braiding angle [0050] The braiding angle, Θ, is the angle between the braided wire on the surface of the wire construction and the longitudinal axes of the wire construction. The braiding angle is defined in DIN 47250 as
    Θ = arctan
    [0051] Here, Θ is the braiding angle; D m is the average diameter of the construction and L is the stroke length. The diameter was measured with an ODAC 15XY laser by a dual axis measurement. The stroke length, L, was calculated from the number of stitches, S, per cm and the number of filaments, N. The stroke length is then
    Determination of fill factor [0052] The fill factor, F, is a measure of the stiffness of the coating threads on the defined surface
    Petition 870180061009, of 07/16/2018, p. 26/58
    22/35 as d
    [0053] Here, t is the title of the coating threads in tex (gram / km), d is the average distance between two parallel threads in the cover, in mm, and p is the density in gram / cm 3 of the polymer of the coating. For the HPPE yarns used p = 0.975 and the polyester yarns used p = 1.37.
    [0054] In Figure 4, the measurement and calculation are illustrated. The average distance between two parallel wires, d, is measured by Scanning Electron Microscopy on a straight piece of wire construction. Draw a (virtual) line, 11, arranged longitudinally in relation to the center of the braid. Choose a first wire and draw a (virtual) line, 12, parallel to the local wire direction at the location where the first wire intersects 11. Count 10 threads from the first wire and draw a (virtual) line, 13, parallel to the local wire direction at the location where the 10th wire intersects 11.
    [0055] Find the middle of 11 between the two intersections of 12 and 13 with 11. Build the shortest line 14 between 12 and 13 through 11. d is the length of 14 divided by 10. In the ideal case 12 and 13 are parallel and 14 is perpendicular to 12 and 13, but small deviations are susceptible.
    Bending strain stress [0056] Multifilament yarn constructions are tested according to ASTM D 790-07. However,
    Petition 870180061009, of 07/16/2018, p. 27/58
    23/35 some slight modifications to the method described in the standard are required to take into account the conditions of the present case.
    [0057] ASTM D 790-07 assumes a span for depth ratio of 16, as in the normal case. Paragraph 7.5 of the standard discusses the possibility of using a greater ratio of span to depth. The highest ratio is recommended for high strength composite materials. The specimens present are not compounds of high strength, but the preferred components are high strength threads, such as HPPE threads. So reasons for recommending a higher span to depth ratio applied to the current model as well, and the next largest span to recommended depth ratio of 32 was adopted for the current specimens.
    [0058] The second difference is the shape of the cross section. ASTM D 790-07 was written for specimens with rectangular sections. The cross sections of the multifilament yarn constructions according to the present invention are substantially circular. The use of cross-sections other than the rectangular cross-section described in ASTM D 790-07 does not violate the physics of the flexion test. However, formulas that translate loads to stress and stiffness must be adapted to other geometries. The formulas in ASTM D 790-07 are derived from the elementary beam theory. Beam theory also offers such formulas for circular cross sections. The modifications are as follows:
    [0059] In equation (3) of the ASTM D 790-07 standard for the bending force

    σ ζ =% PL / n, d 3 [0060] In equation (6) of ASTM D 790-07 for the module
    E h = Úm / 4bd 2 is replaced by:

    [0061] ASTM D 790-07 discusses the filament level at which the force is determined. This can be at maximum load, but also at a given filament level. The statement in ASTM D 790-07, that results in filaments with dimensions greater than 5% are no longer valid. Of course, this figure is somewhat arbitrary. Surprisingly, it has been found that multifilament yarn constructions according to the present invention often show a maximum load of filament values of more than less than 5%. They are therefore, in principle, beyond the established validity of the standard. However, the maximum flexural strain strain, ma x, is additionally described together with the flexural strain strain at 5% filament, 05%, (which is within the indicated validity of ASTM D 790-07). also reported.
    [0062] The tension filament curve of the multifilament yarn construction according to the present invention
    Petition 870180061009, of 07/16/2018, p. 29/58
    25/35 is slightly different from that of other materials. However, there are many similarities. The finger at the beginning of the curve, as discussed in ASTM D 790-07, is also present during tests on the construction of multifilament yarn according to the invention. This finger is due to the drop etc., as discussed in the ASTM D 790-07 standard and is therefore neglected, so that the module is derived from the steeper part of the curve, as recommended in the standard. In fact, most tests show a reasonably straight area on the load displacement diagram, after overcoming the finger region. This reasonably linear area in the region with the steepest slope and, in fact, shows characteristics of a real module and, therefore, is referred to as Etrue in full agreement with the standard recommendation, as presented in section 12.9.1 of the ASTM D standard 7 90-07. The construction of multifilament yarn according to the invention shows a transition to a second linear region of about 2% to 3% filament. This second linear region allows the determination of a secondary module that is additionally reported as E if c. It is a secant module as discussed in paragraph 12.9.2 of the standard. In summary, the results obtained are as follows:

    Exhausted bending strain tension [0064] Traditional rigid cables are steel monolines due to their low cost and high specific rigidity.
    Steel monolines are typically prone to considerable cold bending work and therefore usually exhibit major changes in properties under repeated bending and often even break after just a few bending cycles so multiple remodeling is virtually not possible.
    [0065] Surprisingly, it was found that segments according to the present invention showed a low reduction in flexural strain strain after repeatedly flexing (hereinafter referred to as the exhausted flexural strain strain, 05%, 5). In a preferred embodiment of the present invention, the strain strain of
    Petition 870180061009, of 07/16/2018, p. 31/58
    27/35 exhausted flexion, 05%, 5, of the segment is more than 50% of the flexion strain strain, 05%. More preferably, 05%, 5 is more than 55% of 05%, and more preferably 05%, 5 of the segment is more than 70% of 05%. The high exhausted bending strain strain is highly advantageous in that the wire constructions comprising the segments of the present modality can be reformulated several times by the end user (for example, a surgeon) without the end user experiencing a major change in behavior flexion.

    [0074] From the results of Table 4, it can be seen that the stiffness, as indicated by 05% and the max of the multifilament yarn constructions according to the invention is a complex function of a number of parameters.
    However, a number of trends are observed.
    At an angle that the
    general, it was found that the greater
    braiding, more construction lasts in thread in multifilaments. Beyond addition, the greater O factor in fill, more construction lasts in thread in multifilaments. Finally, the greater rigidity was observed
    for samples with a smaller area in% coating compared to the core.
    Example 6: Measurement of the exhausted bending strain tension [0075] The sample consists of a one-meter piece of the segment to be investigated. In the middle of the sample (50 cm each side), the segment is bent at an angle of 0 90 along one edge with a curvature with a radius of 1 mm, after which the segment is straightened. Flexion is performed 5 times at the same location after which the flexural strain strain (referred to as the exhausted flexural strain strain, 05%, 5) is measured as described elsewhere here. The exhausted bending strain stress is compared with the bending strain strain of a sample not being exposed to repeated bending.

In Figure 6, the filaments (dark spots) are arranged as distinct points with large areas with the most lightweight resin used for image preparation. In Figure 7, the filaments are very closely arranged and it is clearly seen that most of the filaments are strongly deformed. The coating is still seen as a separate area, but the space between the core and the coating is very small and only small amounts of the lighter resin phase are observed.
