    [0001] The present invention relates to an adhesive tape having a backing comprising a stitched nonwoven and a layer of glue applied at least on one side to the backing, the nonwoven sewn containing fibers, which are integrally made of polyester (PES ), especially polyethylene terephthalate (PET) and which are sewn by means of at least one sewing thread. Sewn nonwoven in this context means a fiber-based textile structure which consists of several fiber-based layers sewn together by means of at least one sewing thread. An adhesive strip comprising a support formed from a nonwoven sewn according to EP 0 668 336 B2 is known by way of example. Furthermore, an adhesive tape of the type indicated in the introduction which is marketed under the product name "Coroplast 8550 X" is known. The type of known adhesive tape is adapted to be wrapped around cable sets in vehicles, in order, for example, to avoid rattling noise. Said noises related to rattling are caused for example by the contact of the cables with the bodywork or other parts. Adhesive tapes of the type indicated must fulfill, in view of their use characteristics, common criteria, in particular to comply with standard LV 312 (10/2009). Said standard ranks the adhesive tapes with respect to their application characteristics in the automotive industry, preferably to gather and surround lines and sets of lines. The standard referred to above was developed by the representatives of the car manufacturers AUDI AG, BMW AG, Daimler AG, Porsche AG and Volkswagen AG. When reference is made in the following text to LV 312, the corresponding version 10/2009 in force on the date of filing of the application is systematically implied. Adhesive tape usage characteristics include, for example, the adhesive force on the back of the web and the unwinding force, as well as the manual tearing ability. Other characteristics of use are adhesion strength on defined materials, thickness, elongation at break, tensile strength, resistance to tear propagation, wear resistance and temperature resistance. Depending on the field of application in the automotive industry, adhesive tapes must be used which must have a temperature resistance in the presence of temperatures above 125 ° C. Due to the lack of temperature resistance, it is not possible to use PES non-woven adhesive strips in the presence of temperatures above 125 ° C. Since the operating temperature is limited to 125 ° C., nonwoven adhesive strips of this type are preferably used in the vehicle interior. Similarly, said nonwoven adhesive strips used in the passenger compartment of the vehicle have, because of their high suction action, a moderate resistance to chemicals, which is a drawback. It is an object of the present invention to improve the characteristics of use of the previously known adhesive tapes of the type indicated in the introduction. In particular, it aims to provide an adhesive tape of the type indicated in the introduction having resistance to temperatures above 125 ° C, the resistance of said adhesive tape to chemicals should preferably also be improved. Said object is achieved according to the invention by means of an adhesive tape having a support comprising a stitched nonwoven and a layer of adhesive applied at least on one side to the support, the stitched nonwoven containing fibers which are integrally made of polyester and which are sewn by means of at least one sewing thread, characterized in that the sewn nonwoven contains, in addition to the fibers made of polyester, two-component fibers. Two-component fibers are synthetic fibers that are made from two polymers with different physical and / or chemical characteristics. The specificity of two-component fibers lies in their tendency to curl, which is achieved by the ability to retract different from the two components. In the present case, different fibrous structures are possible, for example two-component fibers comprising two polymers, arranged side by side, of a fiber (in English, side-by-side) or two-component fibers comprising a central polymer and an outer polymer surrounding the first (in English, centric-cover-core). In addition, two-component fibers having a structure identical to that of a multifilament are also conceivable. In other words, the fibers consist of a central polymer, which is surrounded by an outer polymer, knowing that ramifications of the central polymer extend, for example radially symmetrically, in the cross section of the fibers relative to to the outer polymer. It is also possible hollow fibers having various polymers disposed on the outside. The bicomponent fibers may also consist of a polymer fiber, in which are non-homogeneously arranged partial fibers of a second polymer (in English, matrix-fibrill). Bicomponent fibers, polyesters with different melting points based on polyethylene terephthalate (PET), polybutylene terephthalate (PBT) and polyethylene terephthalate (PTT) can be used as materials. Also suitable for said fibers are polyethylene (PE), polypropylene (PP), polyurethane (PUR), ethylene polynaphthalate (PEN) and polyacrylonitrile (PAN) materials. In an advantageous embodiment of the invention, the adhesive strip has a temperature resistance at a temperature in the range of 125 ° C to 175 ° C for a storage period of 240 hours to 3000 hours depending on the temperature. Standard LV 312. In particular, the adhesive tape can be torn by hand according to LV 312. This makes it easy to treat the adhesive tape. Advantageously, the adhesive strip has an elongation at break within a range of 10%, possibly 20%, to 80%, preferably in the range of 50% to 60%. Preferably, the adhesive tape has a breaking force in the range of 15 N / cm to 30 N / cm, preferably up to 50 N / cm. In particular, the adhesive strip has a glue application in a range of from 20 g / m 2 to 150 g / m 2, preferably from 30 g / m 2 to 100 g / m 2, particularly preferably only up to 80 g / m2. Due to the lower air permeability of the adhesive tape according to the invention comprising a proportion of two-component fibers in comparison with webs having conventional non-woven backings without a two-component fraction, the surface of the non-woven fabric comprises -fabricated PET is smoother. Surprisingly, only a much lower glue application is desirably required to achieve the same adhesion forces. In an advantageous embodiment of the invention, the adhesive strip has a wear resistance in the range from class B to class C according to LV 312. Preferably, the fibers made of polyester ( PES) have a fiber length in the range of 60 mm to 120 mm. Advantageously, the bicomponent fibers have a fiber length in the range of 30 mm to 55 mm.
    [0002] In particular, the stitched nonwoven has a PES fiber fraction in the range of 50% to 90%, and correspondingly a two component fiber proportion in the range of 50% to 50%. 10%.
    [0003] In an advantageous embodiment of the invention, the polyester fibers (PES) have a titer in the range of 2.0 dtex to 4.0 dtex, knowing that they are sewn with sewing threads which may preferably have a titer in the range preferably from 40.0 dtex to 60.0 dtex. The ratio in terms of dimensions between the fineness of the fibers and the title is accordingly preferably in a range from 2:50 to 4:50. The bicomponent fibers may in particular have a titer in the range of 1.0 dtex to 7.6 dtex, preferably in a range of 1.5 dtex to 5.0 dtex. The ratio in terms of dimensions between fiber fineness and title is therefore preferably in the range of 1:50 to 5:50. On the other hand, the ratio in terms of dimensions between the fineness of the PES fibers and the fineness of the two-component fibers is preferably approximately 1: 1. In the case where these two types of fibers have a similar value, the characteristics of the nonwoven can be adjusted taking into account the respective material of the fibers and the length of the fibers. Advantageously, the stitched nonwoven has a thickness in the range of 0.10 min to 1.00 m, preferably in the range of 0.15 mm to 0.90 mm, according to the LV standard. 312.
    [0004] The stitched nonwoven has in particular a weight per unit area in the range of from 50 g / m 2 to 230 g / m 2, preferably in a range of from 60 g / m 2 to 130 g / m 2. Other advantageous configurations of the invention emerge from the following description of the figures and the dependent subclaims.

    [0006] Regarding the description which follows, it is requested not to limit the invention to the exemplary embodiments and, in this context, not to limit it either to all characteristics or to several characteristics of combinations of characteristics described. On the contrary, each specific partial characteristic of the example or of each embodiment, even without any link with all the other partial characteristics described in this context, is, in itself and also in combination with any characteristics of another example. embodiment, an importance for the object of the invention.
    [0007] The parameters of the characteristics, explained in the description, of the nonwoven sewn 2 and the adhesive strip 1 are defined according to the standard LV 312 (10/2009). Among these parameters are the stitched nonwoven 2: the thickness D1, the elongation at break, the breaking force, the resistance to tear propagation, the ability to be torn by hand and the permeability in the air. In the present case, with regard to the ability to be torn by hand, a classification is made below. These parameters include, for the adhesive strip 1: the thickness D2, the elongation at break, the breaking force, the adhesion force on the steel, the adhesive force on the back of the strip , unrolling force, tearability by hand, temperature resistance, wear resistance and soundproofing. For the last two parameters, one proceeds in the following description to a classification. FIG. 1 represents an adhesive tape 1 according to the invention, having a support 6 formed from a stitched nonwoven 2 and a layer of adhesive 7 applied on one side to the support 6. The nonwoven stitched 2 preferably comprises a nonwoven textile material, which constitutes a textile flat structure consisting of an alignment and / or a stack of fibers 3, 4 ordered and disordered. The nonwoven material may be long fibers extending along the stretching direction of the web and transverse fibers extending transversely of the long fibers or of an integrally entangled fiber layer.
    [0008] According to the invention, the nonwoven sewn 2 has polyester fibers 3 (PES), preferably polyethylene terephthalate (PET). Advantageously, the nonwoven sewn 2 contains two types of fibers, namely PES fibers 3 and bicomponent fibers 4. The title of the fibers in PES 3 is in particular in the range from 2.0. dtex at 4.0 dtex, and the titer of the bicomponent fibers 4 is in particular in the range of 1.0 dtex to 7.6 dtex, preferably in the range of 1.5 dtex to 5.0 dtex. In order to form the stitched nonwoven 2, the PES fibers 3 and / or the bicomponent fibers 4 are advantageously sewn with sewing threads 5, which preferably have a title in a range preferably from 40.0 dtex to 60.0 dtex. The sewing threads 5 are preferably sewn into the stitched nonwoven 2 with a stitch length s ranging from 0.8 mm to 1.2 mm, preferably with a stitch length s of 1.0. mm. By stitch length s is meant in this context the spacing between the entry location of the sewing thread 5 into the fibrous structure and its exit location. In particular, the stitched nonwoven 2 has a weight per unit area in the range of 70 g / m 2 to 90 g / m 2, preferably in the range of 75 g / m 2 to 85 g / m 2. On the other hand, the stitched nonwoven 2 preferably has a thickness D1 in the range of 0.10 mm to 1.00 mm, in particular in the range of 0.15 mm to 0.90 mm, particularly preferably up to 0.60 mm. A stitched nonwoven 2 is made for example as schematically shown in FIG. 3. In this case, FIG. 3 schematically illustrates a stitched nonwoven 2 which, if the value of the stub K illustrated in FIG. Figure 3 is equal to 25.4 mm, is manufactured with fineness F 3. The fineness is in this case a measure of the density of the stitches. It is based on the "English finesse", which indicates, according to a numbering system applied in the case of knitting machines, the number n of the 30 sewing needles 9, 9 ', 9 "belonging to the section K of an English thumb (25, 4 mm) and in doing so the density of the stitches Thus, in the nonwoven 2 illustrated diagrammatically in FIG. 3, for example, n 3 needles 9, 9 ', 9 "arranged on a section K were used for produce the nonwoven sewn 2. English fineness is standardized in DIN ISO 8188: 2009-02 "Textile machinery and accessories - classification of machines forming meshes". According to the invention, finer values in the range from F 14 to F 24, in particular F 22 fineness, are preferred in this context. By way of example, for the production of a non-ferrous stitched woven 2, two sewing thread systems (eg two bars) to make stitches through the raw nonwoven 2a. Nevertheless one-bar or three-bar systems are also possible. In the case of the two-bar system, a sewing thread 5 is guided by a first set of movable sewing thread guides 8, 8 ', 8 "which are supported by a first guide bar (not shown), in for meshing by integral thread cooperating with the needles 9, 9 ', 9 ", etc. on the width of the raw nonwoven 2a.
    [0009] In order to produce the stitches in the stitched nonwoven 2, the sewing thread 5 is in operation moved to engage the needles 9, 9 ', 9 ", which again guide the sewing thread 5 according to a reciprocating movement through the raw nonwoven 2a.This results in a set of interacting sewing thread stitches which extends along the raw nonwoven 2a in spaced apart rows. Sewing thread stitches 10 may be maintained, by way of example and without limitation, in a complete chain stitch configuration although other known sets of stitches, for example knitting stitches. and the like can also be used.
    [0010] In particular, the nonwoven sewn 2 can be manufactured using the knitting technology "Maliwatt". According to the Maliwatt process, a raw nonwoven 2a is consolidated in that the latter, for example in the form of a pre-laid cross-laminated flock or an entangled nonwoven, is sewn by one or two wire systems. For this purpose, a closure thread / slide needle system is stitched through the fiber web and pulls, upon the return movement, one or two sewing threads 5 placed through the raw nonwoven 2a. to consolidate. It follows the slaughter of the mesh that precedes and the withdrawal of the material down. The yarn material of the sewing threads 5 may consist wholly or partly of textile fibers. Yarns may be used as an example, since yarns made of staple fibers or filaments may be used. A staple fiber yarn is made of finite length fibers, which are twisted during spinning. A filament yarn is made of filaments. A filament is a fiber with unlimited length (according to DIN 60000 (10/1990)) or has a length of at least 1000 mm (according to DIN 60001 (10/1990)). On the other hand, fibers with a limited length of fibers to be spun (from the German "Spinnfasem") are designated. Once again, the spinning fibers are divided into staple fibers (from the German "Stapelfasern") that can be spun in practice and, on the other hand, into very short knives, knowing that the limit is the order of 15 mm. Sewing threads 5 can also be produced from spinning fibers. Sewing yarns 5 are preferably used for threads, in particular so-called pre-oriented yarns (POY) or so-called fully drawn yarns (in English). English, FDY - Fully Drawn Yam). The manufacture of a filament yarn is achieved by the entanglement of the various filaments. In particular, the sewing threads contain from 24 to 144 filaments. Preferably, the number of the filaments is in a range from 34 to 38. The characteristics of an embodiment of the stitched nonwoven 2 are illustrated in Table 1 which follows, column 4. The information "PES Virgin Table 1 for the material of the fibers 3, 4 and the sewing thread 5 in this case means that the fibers 3, 4 and the sewing thread 5 are preferably made partly or wholly of a polyester. not recycled. The sewing threads 5 may consist wholly or in part of a recycled or non-recycled polyester (PES), polyamide (PA), polyethylene (PE) or polypropylene (PP) or polyurethane (PUR) .
    [0011] In the stitched nonwoven 2 used in the carrier according to the invention, the PES 3 fibers comprise a proportion in the range of 50% to 90%, and the bicomponent fibers 4 correspondingly comprise a proportion of in the range of 50% to 10%.
    [0012] The length of the fibers in PES 3 ("fiber 1") is in a range from 60 mm to 120 mm. The two-component fibers 4 ("fiber 2") have a length in the range of 30 minutes to 55 mm. On the other hand, the stitched nonwoven 2 has an elongation break in the range of 13% to 25% and a breaking strength in the range of 20 N / cm to 32 N / cm. In this case, the breaking force is a measure of the load capacity of the adhesive tape 1 during use. The elongation break is a measure of the extensibility of the adhesive strip 1. The tear propagation resistance (VM = average value) is equal to 10,000 mN. Resistance to tear propagation or notch resistance is the ability of a material to resist the propagation of tears even in the presence of a notch. This characteristic is correlated with the ability to tear by hand. - 12 - Table 1: Overview of support materials Parameter Unit Stitched nonwoven In accordance with the invention Standard PET with fibers of 80 g / m2 two components Fineness n / 25 mm F22 F22 Title Dtex 50 50 Number of Number 36 36 filaments Stitch length Mm 1,0 1,0 Yarn material PES Virgin PES Virgin Virgin fiber PES Virgin PES Virgin PES fiber Fiber material - Two polymers Two-component fiber Title Fiber in PES Dtex 2,1 2,0 - 4.0 Title Fibers to two Dtex 1.0 - 5.0 components Proportion fiber in% 100 50 -90 PES Proportion fiber to% 0 10 - 50 two components Fiber length Mm 76 60 - 120 Fiber 1 Fiber length Mm 51 30- 55 Fiber 2 Surface mass g / m2 80 +/- 5 80 +/- 5 Thickness Mm 0.175 +/- 0.015 015, +/- 0.03 Elongation at% 15 -35 20 -80 rupture Breaking force N / cm 25 -40 15 -30 Resistance to MN VM 13 000 VM 10 000 tear propagation Capacity to LV 312 Moderate Very Moderate Hand Tear Permeability to Air 1 / m2 * s 2500 - 3000 1000 -2000 The nonwoven sewn 2 can very easily tear by hand. The air permeability is in particular in a range from 300 1/1-n2s to 2500 1 / m2s, preferably in a range from 400 1 / m2s to 20001 / m2s. This is a function of the proportion of two-component fiber used. The use of a stitched nonwoven 2 as a support 6 preferably gives rise to an adhesive tape 1 having the characteristics shown in column 5 of Table 2 (FIG. 4) in comparison with conventional adhesive tapes. In the present case, the characteristics detailed in Table 2 are important for the invention, either alone or in any combination. The adhesive layer 7 of the adhesive tape 1 according to the invention preferably comprises adhesive substances, sensitive to pressure, in particular based on polyacrylate, which can be used because of their satisfactory resistance to aging. Acrylate-based adhesives can generally be applied either in the form of a dispersion or in the form of fusible adhesives to be crosslinked by means of UV radiation. In principle, the use of acrylate-based solvents is also possible or the use of mixtures of acrylate monomers or acrylate prepolymers. These are optionally polymerized and crosslinked after coating either thermally or by means of UV radiation. Moreover, the use of other classes of hard adhesive substances such as synthetic rubber-based adhesive substances, such as SIS (styrene-isoprene-styrene copolymer) or SBS (styrene block copolymer) -butadiene-styrene) or adhesive substances based on silicone or polyurethane, is also possible. For the manufacture of the adhesive tape 1, an application of glue on the support 6 of the stitched nonwoven in a range from 30 g / m 2 to 80 g / m 2 is in particular required. On the other hand, the adhesive tape 1 has an elongation at break of 18% and a breaking force of 27 N / cm. Moreover, the adhesion strength on the steel is 2.1 N / cm, the force adhesion on the back of the band is 4.5 N / cm. The adhesive tape 1 made with the stitched nonwoven 2 has a stripping force of 6.2 N / cm. The unwinding force is in this case the force required for the unwinding of an adhesive tape roll. It acts on the winding tension during the application of strips on sets of lines, which for example impacts the winding hardness of a bundle of lines. Unwinding forces which are too high may result in twisting and thereby shortening, particularly of small line bundles. Unwinding forces that are too low can give rise to machining problems and in addition to soft-line bundles with incorrect and loose windings. In addition, the soundproofing of the adhesive tape 1 corresponds to the class C, and the wear resistance is in a range from class B to class C. The following table 3 gives an overview of the classes in question. wear material according to LV 312 (10/2009), while table 4 shows an overview of the soundproofing classes according to LV 312 (10/2009). The temperature resistance of the adhesive tape 1 is preferably in the range of at least 125 ° C, preferably in the range of 150 ° C to 175 ° C.
