专利说明:

To integrate conductive elements to obtain a material that can be heated and / or provided with functions such as sensing moisture or measuring temperature. A known problem in this field of technology is how to protect the conductive parts of a textile (or any functional filament) from external wear that could interfere with or even damage the function.
BRIEF DESCRIPTION OF THE INVENTION It is an object of the invention to solve or at least minimize the above-mentioned problems. This is accomplished by a three-dimensional woven fabric comprising at least two layers extending substantially parallel to each other, said woven fabric further comprising at least one interconnecting structure between said at least two layers, the interconnecting structure further preferably comprising a plurality of spacer layers each spaced apart. between the adjacent at least two layers.
In the production of the fabric according to the invention, the at least two layers and the intermediate bonding structure are woven simultaneously in a single step, meaning that a finished layer of textile is obtained directly from the weaving machine.
The majority of advantages are obtained thanks to the layered textile according to the invention, which textile comprises at least two layers (a first upper and a second lower layer) bonded and stabilized by an intermediate bonding structure. According to an example of the invention, the intermediate structure constitutes an intermediate support layer in the textile which stabilizes the two adjacent outer layers, and which at the same time makes the textile soft and flexible. Thus, the ﬂ layer textile is excellent as an upholstery and clothing material, e.g. for furniture, car seats and / or mattresses, and is thus a suitable replacement for conventional laminated composite materials.
Since the lag layer fabric is woven in a single step, it can be taken directly from the weaving machine and 'taken to an upholsterer and / or other manufacturers without any need for subsequent treatment before further use. Above all, labor-intensive lamination and / or gluing procedures are avoided when assembling the textile, which saves time and reduces the costs of manufacturing upholstery materials.
In addition, the materials used to weave the fabric according to the invention are preferably recyclable, which means that the material constitutes an environmentally friendly alternative to currently existing composite fabrics and currently existing upholstery materials and / or structures. Another advantage achieved by the fabric according to the invention is that the woven material can be made with outer layers which are strong and durable, while at the same time they can be given a dense and even surface, which in particular in the case of materials which are intended to constitute a seating area e.g. on a sofa, armchair or car seat, is a required feature.
In addition, individual or all of the different layers could include yarns that provide a certain function, e.g. conductive yarn, which could lead to the textile being associated with some function. For example, if such a conductive yarn were to be integrated within the middle layer of the fabric according to the invention, these yarns would be protected from external wear, which helps to avoid short circuits and / or prolongs the life of the function of the fabric in question.
Each of said at least three layers (ie upper, middle and lower layers) in the textile according to the invention is woven independently of, but at the same time, the others in a weaving machine, implying that for example the yarn quality as well as the thickness and design of upper, middle and lower layers can be selected individually. The surface design of the upper layer and the surface design of the lower layer of the layer textile can be designed independently of each other. This leads to a variety of possible variations of textile design and quality, respectively, which makes it possible to adapt the design to specific needs. If, for example, the textile is intended to dress an office chair, the upper side of the textile which will be facing outwards could be woven with a certain pattern, in a special color or in a quality such as is made extra smooth and soft, in order to provide a comfortable seat. Thanks to the weaving method according to the invention, it is at the same time, for example, possible to weave the lower (covered) layer in a cheaper material and / or more / less durable than the outer layer.
Another suitable area of use for ﬂ erlager textiles is interior architecture, especially due to its good absorbency of sound waves. Thanks to its construction, the fabric can be designed specifically to attenuate noise (for example by providing the intermediate layer with a voluminous yarn type), which makes the fabric suitable as a wall or ceiling covering. Furthermore, the outer layers of the fabric can be designed and patterned in all the ways made possible by a weaving process. In this way, the textile can, for example, be adapted to drape interior walls and / or ceilings, thereby making it possible to introduce decorative details into a room, while the textile, in its capacity as an effective sound absorber, contributes to a more pleasant and less noisy environment. It is furthermore possible to create an ﬂ bearing fabric according to the invention with lager layers than described so far. In such a variant, said ﬂ bearing layer textile could for example comprise three layers extending substantially parallel to each other in this way corresponding to an upper, a middle and a lower layer, wherein said upper and middle layers correspond to a pair, and said middle and lower layers corresponding to another pair, each pair of parallel layers being connected to each other by a connecting structure in the form of a connecting layer. Each of the two resulting connecting layers in the given example is during the weaving process in turn woven between, and integrated with, one of said pairs of layers, so that they thereby form a number of spacer layers. Said three layers and said two connecting layers in the given example are woven during the manufacturing process simultaneously with each other in a weaving machine, thereby producing a fabric with five layers, where each layer can be designed individually, while the fabric as such is still produced in a single manufacturing process.
The five layers as referred to in the examples given above would then consist of: a first top layer, a second interconnecting layer, a third intermediate layer, a fourth connecting layer and a fifth bottom layer. Such a textile can be used as a functional material where conductive yarns are for example integrated within one of the inner layers (within any of the connecting layers or within the third middle layer) which means that the conductive yarns are protected from external wear at least by the top and bottom layers.
It is understood that "yarn" and "thread" means any kind of yarn, thread or other suitable filament that can be used in weaving. Yarns / yarns that can be selected for the invention can be selected depending on the purpose of use. Examples of suitable yarns / yarns comprise, in addition to mono- lament, spun yarn, voluminous yarn or stretchable yarn. Material for warp and weft used in said layers in the textile can be chosen freely and examples include polyester, nylon, cotton, wool and metal.
According to a further aspect of the invention, each of the interconnecting structures consists of a continuous layer which is arranged to be directed back and forth through the weaving process in an alternating manner between two adjacent layers so as to form multiple fold structures along the space between adjacent upper and lower layers. . The interconnecting structure, in the form of said folding structures, comprises warp yarns and preferably also weft yarns, meaning that it consists of a woven material where weaving takes place simultaneously with weaving of other layers which make up the textile. It is understood that the term "directing said continuous layer back and forth" means that the woven intermediate layer is caused to be attached to, and integrated with, the respective upper and lower layers in an alternating manner during the progress of the weaving process.
Preferably, the material used as a warp yarn in said bonding structure is a resilient material such as polyester or nylon.
The material used for weft yarns in said connecting layer can be chosen freely depending on the purpose of use. Examples of suitable materials for in said bonding layers may include metal, optical fiber, polyester, cotton, wool and other synthetic materials such as polyvinylidene chloride, polypropylene sulfide, polyethylene naphthalate.
During weaving, the interconnecting layer will alternate between first attaching to the adjacent upper layer, and then attaching to the adjacent lower layer of the fabric so as to form said number of fold structures. The result is a number of interconnecting bridges that go from one layer to the other. The bridge formations are also referred to herein as “spacer layers.
The intermediate interconnecting structure and its spacer layers will be substantially covered by adjacent textile layers. Above all, the weft elements belonging to the intermediate layer will be completely protected from the external environment, which is particularly advantageous for certain types of yarns which may be sensitive to touch and wear.
An example could be conductive elements or conductive materials that can be integrated with / within the fabric to create a system that provides a sensor function. A sensor function could be e.g. to heat the material, register pressure, ﬁ act or temperature. If such a lament were to be introduced as a weft within the bonding layer, these laments would be completely and effectively protected from the outside of surrounding textile layers.
According to a further aspect of the invention, said textile may be designed to comprise a particularly high absorption factor. It is understood that by "absorption factor" is meant the quality of being absorbent, by which is meant the ability to absorb high sound waves. By creating a interconnecting structure that comprises voluminous weft elements, an intermediate layer with a high absorption factor can be achieved. Preferably, said storage textile can be given an absorption falsifier between 0.4 - 0.8 'for 500 Hz, and between 0.7 - 1.1 for 1 - 5 kHz.
It will be appreciated that said layered textile may comprise one or more than one interconnecting layer, which interconnecting layer may interconnect one or two pairs of layers, and where each interconnecting layer could comprise functional elements.
BRIEF DESCRIPTION OF THE FIGURES The fabric and method of weaving the same will be described in more detail below with reference to the accompanying figures. The following description is to be considered only as a preferred embodiment and not limiting of the invention.

DETAILED DESCRIPTION OF THE DRAWINGS Fig. 1 is an example of a piece ﬂ bearing fabric according to the invention where said piece comprises a top surface 13, a bottom surface 14, a short side 2 and a long side 3 where the short side 2 corresponds to the side determined of the width of the weaving machine in which the textile is manufactured, and where the long side 3 corresponds to the side of the textile which is discharged from the weaving machine as the weaving continues.
Furthermore, the fabric according to the example in Fig. 1 comprises two layers extending substantially parallel to each other: an upper layer 10 and a lower layer 11. Each of said layers 10, 11 in the three-dimensional woven layer textile 1 comprises warp yarns and weft yarns directed along a first and second directions, respectively, which first and second directions are substantially perpendicular to each other in accordance with conventionally woven textile materials.
The upper 10 and lower 11 layers are interconnected by an intermediate structure 12 which is arranged to zigzag between the upper layer 10 and the lower 11 layer, thereby providing a plurality of spacer layers 121 each extending between the two layers 10. , 11. As seen at one long side 3 of the textile piece in ﬁ g. 1, and which will be explained in more detail in connection with the guras 2a-2d, the intermediate structure 12 corresponds to a continuous layer which is attached to, and directed back and forth between, the two adjacent upper 10 and lower 11 layers in the textile 1 which leads to multiple folds being created along the longitudinal direction of the fabric.
Said interconnected structure 12 in said woven fabric contains warps 122 extending substantially along a third direction, the third direction being substantially perpendicular to both said first and second directions (wherein said first and second directions are defined by the directions of the warp and weft in the at least two bearings 10, 11). As a result, the warps 122 extend within the interconnecting structure 12 in such a way that it intersects the planes as they are formed by each of the adjacent at least two layers 10, 11, and binds together the at least first and second layers.
Attaching the intermediate layer 12 to the adjacent layers is accomplished during the weaving process, the intermediate layer 12 being woven simultaneously with the upper and lower layers. The warp in the woven bonding layer is alternately integrated with the warp of the upper and lower 111 layers, respectively, preferably forming spacer bridges 121 between the two. Said bridges 121 (also called spacer layers) extend between the upper layer and the lower layer 11, however, it should be understood that the number of spacer layers 121 are all part of a continuous layer which preferably consists of warp and weft. It is also possible to allow the intermediate layer 12 alternatively to be integrated with the upper 10 and the lower 11 layer without forming any spacing bridges between them, which would mean a form of drying according to the invention where the upper 10 and the the lower layer 11 are arranged tightly connected in parallel with each other and fastened through the intermediate layer 12.
The circled enlargement of a corner piece of the textile 1 in Fig. 1 shows that the connecting layer 12 connects the upper 10 and the lower 11 layer to each other, at the same time as it forms a plurality of spacing layers 121. Furthermore, the connecting layer 12 shows that the connecting layer 12 the given example comprises warp 122 and weave 123. The weft threads 123 in the intermediate layer 12 are protected by the upper 10 and lower 11 surfaces, respectively. The weft 123 in said intermediate layer 12 is preferably made of a synthetic material, such as polyester threads or some other resilient material which will give stability but at the same time give a certain soothing property to the textile. It is understood that by "resilient property" is meant that the fabric will regain its original shape after being compressed.
Fig. 2a shows a part of a cross section taken somewhere along line IIa in ﬁ g. 1. This figure further clarifies that the intermediate layer 12 alternates between being bonded to the upper 10 and the lower 11 layer. The overall thickness of the fabric is referred to as TW, the thickness of the upper layer is referred to as T1, the thickness of the lower layer is referred to as Tg, and the distance between the upper and lower layers is referred to as d.
The distance d is predetermined before weaving and can be varied depending on the required quality of the final textile material. A part 121 of the intermediate layer 12 which extends between the two adjacent layers over the distance d is referred to as "distance layer". A large distance d will lead to higher ibil visibility in the textile structure while a shorter distance d will lead to a textile that is more stable and rigid.
It is possible to construct a textile according to the invention where TM essentially corresponds to T1 + Tz, which would mean that the intermediate layer 12 will alternate between being integrated as a warp in the upper layer and being integrated as a warp in the lower layer, and have the function of holding the two layers together. The thickness of the upper T1 and lower T2 layers can be varied by choosing a thicker or thinner thread for the warp and weft, respectively, when weaving a specific layer.
Fig. 2b is a cross-sectional view showing another example from a view corresponding to that shown in. G. 2a where an upper 10 and a lower 11 layer are connected to each other by a spacer connecting layer 12. The connecting layer 12 comprises a plurality of spacer layers 121 and alternately between attaching to the upper and lower layers, respectively.
When weaving the fabric, the warp threads 123 of the interconnecting layer 12 are integrated with a portion of the layer to which it is intended to be attached (eg the upper) before being passed on to the second layer (eg the lower) and attached in a corresponding manner.
In the example in ﬁ g. 2b, the layer of textile 1 is woven with a smaller number of spacer layers 121 along a given length of the fabric ironed with the fabric of ﬁ g. 2a, meaning that during weaving, longer pieces of warp 122 from the intermediate layer 12 will be integrated in the upper 10 and the lower 11 layer, respectively.
Fig. 2c illustrates another example of a layered textile according to the invention, wherein three layers 10, 11, 15 extend substantially parallel to each other, said three layers 10, 11, 15 being interconnected by two interconnecting structures 12, 12 "each of which comprises a plurality of spacer bearings 121 (also referred to as spacer bridges). It is to be understood that the interconnecting layers of one type of ﬂ bearing layer fabric may be designed individually and independently of other layers. This means, for example, that the intermediate layer 15 could be provided with conductive wires, and that surrounding connecting structures 12, 12 "can be designed to protect said conductive wires from e.g. short circuits and / or external wear. This can be accomplished by inserting thick, non-conductive weft threads into said adjacent interconnecting layers 12, 12 ".
Furthermore, as seen in ﬁ g. 2c, the distance d; between the upper and middle layers is made shorter than the distance d; between the middle and the lower layer, and it is equally possible to vary the number of spacer layers 121 along a given length of the fabric. Each of the described variants of design on the textile according to the invention will result in a certain quality of the textile, where examples of quality may include high or low resistance, stability and / or rigidity. Fig. 3a shows a part of a cross section taken somewhere along line IIIa in ﬁ g. This figure shows how the interconnecting layer 12 extends between the adjacent upper 10 and lower 11 layers, where warp threads 122 from the interconnecting layer 12 are directed substantially perpendicular to the direction of warp threads in the upper 10 and lower 11 layers, respectively. As seen in the example in ﬁ g. 3a, the interconnecting structure 12 also includes weft threads 123 extending horizontally across the warp. These inner weft threads 123 may be of any leathery material and may, for example, have a special function which enables some type of functionality. I ﬁ g. 3a, two weft threads 123 are inserted into the spacer layer, while Fig. 3b shows an example where a number of six weft threads 123 are woven over the warp threads 122. i It is understood that the number of weft threads may be increased, and that the bonding layer textile with tightly woven warp and weft yarn or that can just as easily consist of a layer with multiple adjacent warp threads without, or with a few, weft threads. Each such variant of textile will give the final textile certain properties. For example, a variant of the fabric could be formed with a bonding structure 12 both with a dense plurality of weft threads 122 and a large number of spacer layers 121 over a given length of the fabric which will result in a material with particularly good absorbency. According to an example of the fabric, it could be manufactured to have an absorption factor between 0.7 and 1.1 for frequencies between 1 - 5 kHz.
Fig. 3c shows another example of a cross section of a warehouse textile according to the invention, where the cross section shows the textile from a perspective corresponding to that in ﬁ g. 3a, but shows another example.
I ﬁ g. 3c, a number of three layers 10, 11, 15 propagate substantially parallel to each other.
The upper 10 and the middle 11 layer correspond to a pair, and in the same way the middle 15 and the lower 11 layer correspond to a pair. The layers in each pair are joined together by integrated-interconnecting woven intermediate layers 12, 12 ”. Each of the two bonding layers 12, 12 'comprises warp threads 122, preferably polyester warp, and preferably also a number of weave threads 123. In the example in Fig. 3c, it is possible that the upper bonding layer 12 "acts as an insulator of the lower bonding layer 12, meaning that the conductive threads present in the lower spacer layer of the fabric will be shielded and protected by the upper bonding layer 12 °, which allows t. ex. short circuits can be avoided. Figures 2d and 3d show another example of a cross section of the textile according to the invention, where cross section 2d corresponds to the perspective according to ﬁ g. 2a and cross-section 3d correspond to the perspective according to ﬁ g. 3a.
As seen in ﬁ g. 2d, the fabric is woven in such a way that the distance between the upper 10 and the lower 111 layer is varied for each bridge in the intermediate layer 12. This is achieved by changing the length of the spacer bridges 121 in the intermediate layer 12 along its length. The result of such a design is a textile which has a wavy profile. This type of textile material can be advantageous e.g. as sound-absorbing material because that waveform means that the surface will be directed in different directions, which means that the fabric will absorb sound just as effectively regardless of where the sound source is located relative to the fabric itself.
F ig. 3d shows a cross section according to the same example as in ﬁ g. 2d, taken along line Hld in ﬁ g. 2d. An intermediate layer 12 creates the distance d between the upper 10 and the lower layer 11, however, the distance d varies over the length of the textile resulting in a wavy upper surface 13 and a wavy lower surface 14. In the example in ﬁ g. 3d, said upper 13 and lower 14 surfaces are linear along the direction corresponding to the short side of the fabric.
However, it is possible to allow this surface to assume a wavy profile as well as the one shown in ﬁ g. 2d.
F ig. 4 shows a binding pattern corresponding to an example of a repeating unit of a bearing textile according to the invention. The invention according to the example is a three-layer textile of a loose shaft which has an upper layer, an intermediate connecting layer and a lower layer where each respective layer comprises warp and weave yarns.
Numbers 1 - 16 indicate the warp of the upper layer, the warp of the intermediate layer and the warp threads of the lower layer and the numbers 1 ”- 42” indicate the weft yarn, the weft yarn of the intermediate layer and the weft yarn of the lower layer.
With respect to the numbers indicating the warp yarn, only 1 ”- 4” and 39 ”~ 42” are explicitly shown in ﬁ g. 4, but it is understood that the other numbers 5 "~ 38" are also represented in the form of corresponding intermediate rows in the binding pattern.
In the binding pattern in ﬁ g. 4 indicates the numbers 4, 8, 12 and 16 warp threads in the intermediate layer, and the numbers 1, 2, 5, 6, 9, 10, 13 and 14 indicate warp threads in the upper layer and the numbers 3, 7, 11 and 15 indicate warp threads in the lower part of the fabric according to the invention.
Furthermore, the binding pattern in ﬁ g is indicated. 4 weft yarns in the lower layer at number 1 "-3" and 25 "-29", weft yarn in the upper layer at number 4 "-8" and_22 "-24" and weft yarn in the connecting layer at number 9 "-21" and 30 "-42".
In the present pattern, the mark A means that an upper warp layer lies over an upper weft layer; the marking o means that a lower warp layer lies over a lower weft layer; the markings 0, c, (9 and / means that a connecting warp layer lies over a connecting weft layer; the marking = means weaving of weave ﬁ; in the lower layer; the marking - or ° means weaving of weft in the upper layer; and oo means weaving of weft in the intermediate connecting layer.
When weaving a textile according to the pattern in ﬁ g. 4, weaving will be performed in the following manner. Warp and weft yarns for each layer (upper, intermediate and lower layers) are rigged in the weaving machine, and warp threads are passed through their respective silver shafts. When you start weaving, the machine starts with the weft corresponding to number 1 "and continues upwards according to increasing numbers: 2", 3 °, 4 "and so on up to 42".
First, the machine will weave in the lower layer (1 '-3 "), after which it will weave in the upper layer (4" -8 "). Thereafter, weaving in the bonding layer will take place (9 ° - 21 ") and the warp in the bonding layer will be raised by the corresponding silver shaft so that the warp is placed over the upper layer and integrated with the warp threads in this upper layer.
Thereafter, weaving in the upper layer (22 ° -24 ") continues, followed by weaving in the lower layer (25" -29 "). Finally, the cycle is completed according to the example by weaving in the connecting layer (30 ”-42 °) and then the layer is redirected by lowering the corresponding so that the layer is instead integrated with the lower layer, after which the cycle can be repeated.
Figure 5a is a cross-sectional view taken along lines Va and Vb in ﬁ g. 4 for weft threads 1 "and 2", respectively, where Va corresponds to thread 51 and Vb corresponds to thread 52.
In a similar way, ﬁ g. 5b is a cross-sectional view taken along the lines Vc and Vd in ﬁ g. 4 for weft threads 3 'and 4' respectively. Here Vc corresponds to thread 53 and Vd corresponds to thread 54. 10 15 20 25 30 35 13 F ig. 6b is a cross-sectional view taken along lines V1a and VIb in ﬁg. 4 at warp threads 16 and 15, respectively, where V1a corresponds to thread 61 and VIb corresponds to thread 62. Further. is ﬁ g. 6b is a cross-sectional view taken along lines VIc and VId in ﬁ g. 4, and warp threads 14 and 13, respectively. Vlc corresponds to thread 63 and VId corresponds to thread 64.
Figures 7a and 7b show how a system of warp threads can be arranged to achieve a certain functionality in the textile. In these figures, five warp threads 125, 126, 127, 128, 129 correspond to a profile according to an example of a ware textile.
Two threads, 125 and 129, correspond to the warp in the upper and lower layers, respectively, and three threads, 126, 127 and 128, correspond to the warp belonging to the connecting layer of the fabric. (It will be appreciated that in reality the bonding layer 12 comprises many parallel warp threads not shown in Fig. 7a for the sake of clarity.) A warp thread 126 is made of conductive lamellae, or of a material consisting of a mixture of non-conductive and conductive material. Examples of such materials may be carbon-based, silver, copper or other metals and / or alloys. When weaving the fabric, the conductive warp 126 will be brought to the surface of the fabric at certain limited and predetermined areas whereupon the warp thread forms a kind of cushion 7 of conductive ﬁ lainent. Co-operating wires 127, 128 will be entrained with said conductive wire 126 and may be brought to the surface therewith, e.g. to provide a spacer structure 71 within said cushion 7 and / or to provide insulating protection 127 thereby avoiding short circuits.
The result of such a design is a number of protruding conductive pads 7 at certain predetermined places of the surface of the textile, where the position of said places is determined during the design of a binding pattern for weaving. A textile according to this specific example is seen in ﬁ g. 7b showing a piece of fabric woven with a number of protruding conductive pads 7.
At the part of the fabric where no conductive pads are needed, the warp threads 126, 127, 128 are kept between the warp threads 125, 129 in the upper 10 and the lower 11 layer. A textile with conductive areas, e.g. in the form of said cushions 7, can be used e.g. for pressure sensing on mattress covers in hospitals, where it may be important to monitor lying patients in order to avoid bedsores. In such an application, the conductive pads 7 would correspond to electrodes which are brought into contact with the person while he / she is lying on the textile of approximate design. It is possible to never allow the warp threads in the intermediate layer 12 to come up to the surface, but to allow them to extend between the two adjacent layers 10, 1 1. Such a variant would provide a way to heat the fabric from its inside. By applying a voltage across the conductive elements, the fabric will heat up, which in turn heats up surrounding parts of the fabric.
Said conductive wires 126 could be replaced by any type of wire, conductive or non-conductive, whereby the choice of non-conductive wire would still lead to a certain surface structure corresponding to the surface comprising pads as shown in ﬁ g. 7b.
The invention should not be limited by the embodiments described above, but may be varied within the scope of the appended claims. For example, it should be understood that the fabric may consist of three, five or five layers woven simultaneously according to the method of the invention. Furthermore, it is possible that all layers are woven in the same type of material and, in a corresponding manner, that each layer is made of different types of thread.
