Description

Technical Field

[0001] The present invention relates to the technical field of zipper processing, and more particularly to a high-tension zipper tape and a zipper product. Background Art

[0002] Tensile strength refers to the ability of a material or specimen to resist breaking when stretched, or the maximum tensile force (tensile stress) a material can withstand without breaking. Zippers, which rely on a continuous chain of teeth, are used to connect or separate items and are widely used in clothing, bags, tents, and other items.

[0003] In recent years, with people's pursuit of quality of life, the quality of military bags, outdoor tents, sportswear, swimsuits and other stretchable clothing has been getting better and better. The fabrics of such items have excellent tensile strength, puncture resistance and cut resistance. However, the zipper tapes used with them are made of conventional weaving methods and ordinary polyester yarn, which lacks tensile strength and stretch resistance, making them difficult to be used with the above-mentioned stretchable clothing, outdoor tents, military bags and other special clothing items. Summary of the Invention

[0004] The invention provides a high-tension-resistance zipper tape, so as to solve the problems of poor tension resistance and stretch resistance of existing zipper tapes.

[0005] The present invention adopts the following technical solutions:

[0006] A high-tension zipper tape, which is interwoven by several warp yarns and at least one weft yarn, wherein both the warp yarns and the weft yarns are made of fiber aramid yarns. The zipper tape is divided into a chain tooth stitching area, a rebound shrinkage area and an M twill area in sequence along the width direction. The chain tooth stitching area adopts the method of warp yarns floating on the weft yarns and the weft yarns sinking below the warp yarns, and is interwoven in a mixed manner of one sinking and one floating and two sinking and two floating intervals. The rebound shrinkage area adopts the method of warp yarns floating on the weft yarns and the weft yarns sinking below the warp yarns, and is interwoven in a two sinking and two floating manner. The M twill area adopts the method of warp yarns floating on the weft yarns and the weft yarns sinking below the warp yarns, and is interwoven in a two sinking and two floating manner. After interweaving, the warp and weft yarns in the M twill area are arranged in an "M"-shaped twill pattern.

[0007] Furthermore, the chain element stitching area is formed by interweaving a plurality of warp yarns and a weft yarn in a mixed matching manner of one sinking and one floating and two sinking and two floating, and the matching manner is that the zipper tape is alternately matched in the order of one sinking and one floating, two sinking and two floating, and one sinking and one floating along the width direction.

[0008] Furthermore, the warp and weft yarn areas composed of two sinking and two floating yarns in the chain tooth sewing area form an "M"-shaped twill pattern, and the warp and weft yarn areas composed of one sinking and one floating yarn in the chain tooth sewing area are respectively located on the outermost sides and the middle corner of the "M"-shaped twill pattern.

[0009] Furthermore, the rebound shrinkage zone is formed by interweaving a plurality of warp yarns and a weft yarn in a two-sinking and two-floating manner, and the warp and weft yarns in the rebound shrinkage zone after interweaving are arranged in a plane pattern of alternating sinking and floating.

[0010] Furthermore, the M twill area is formed by interweaving a plurality of warp yarns and a weft yarn in a two-sinking and two-floating manner, and a plurality of warp yarns interwoven in a one-sinking and one-floating manner are inserted into the corners of the "M"-shaped twill pattern of the M twill area.

[0011] A high-tension-resistance zipper comprises a left zipper tape, a right zipper tape, two rows of zipper teeth, a zipper pull, a U-shaped top stop and a square latch, wherein the left zipper tape and the right zipper tape are both made of the high-tension-resistance zipper tape.

[0012] From the above description of the structure of the present invention, it can be seen that compared with the prior art, the present invention has the following advantages:

[0013] 1. The present invention interweaves warp and weft yarns made of fiber aramid yarns, and divides the zipper tape into a chain element stitching area, a rebound shrinkage area, and an M-twill area. The chain element stitching area, the rebound shrinkage area, and the M-twill area are mostly interwoven using a two-sinking, two-floating method. The resulting zipper tape has less interweaving, high weaving efficiency, and a large amount of shrinkage space. At the same time, it has strong elasticity. In combination with the warp and weft yarns made of fiber aramid yarns, the fiber aramid yarns have the high tensile strength, high tension, low elongation (elongation refers to the percentage of the total deformation of the gauge length after stretching and breaking to the original gauge length), cut resistance, and wear resistance. Therefore, the zipper tape has high tensile strength, fracture resistance, low elongation, cut resistance, and wear resistance while ensuring its own elasticity.

[0014] 2. The chain tooth stitching area of ​​the present invention is made of an interlaced mixture of one sinking and one floating and two sinking and two floating structures. It not only has the characteristics of a one sinking and one floating structure, such as being straight and firm, but also has a long floating structure of two sinking and two floating structures. The number of interlacing times is less, which can provide a shrinkage space and facilitate the rapid shuttle of the chain tooth stitching, so as to facilitate the sewing of the chain teeth to the chain tooth stitching area.

[0015] 3. The rebound shrinkage zone of the present invention is interwoven in a two-sinking and two-floating manner, and the warp and weft yarns in the rebound shrinkage zone after interweaving (along the width direction of the zipper tape) alternately sink and float to form a plane pattern. This plane pattern has a long floating structure, a small number of interweaving times, and a plane arrangement with alternating sinking and floating patterns. This can provide a certain amount of shrinkage space in the subsequent electric ironing process, dyeing process, and steaming process of the zipper tape, thereby solving the certain amount of elastic shrinkage of the zipper tape caused by the above processes. At the same time, the alternating sinking and floating plane can prevent the formation of arching defective products between the chain elements and the twill area of ​​the zipper tape M.

[0016] 4. The M-shaped twill area of ​​the present invention, which constitutes the main body of the zipper tape and accounts for more than half of its composition, employs two sinking and two floating patterns to create a continuously curved "M"-shaped twill pattern, resulting in excellent stretchability and elasticity. Furthermore, two warp yarns, one sinking and one floating, are interwoven at the corners of the "M"-shaped twill pattern. These warp yarns are also made of aramid yarn, resulting in frequent corner interweaving and increased flexure, further enhancing the zipper tape's resistance to tension while maintaining a clear pattern.

[0017] 5. The warp and weft yarn areas composed of two sinking and two floating yarns in the stitching area of ​​the chain teeth of the present invention form an "M"-shaped twill pattern. The "M"-shaped twill pattern cooperates with the pattern of the M twill area, making the zipper tape more coordinated as a whole and having better stretchability. At the same time, the warp and weft yarn areas composed of one sinking and one floating yarn in the stitching area of ​​the chain teeth are respectively located on the outermost sides and the middle corner of the "M"-shaped twill pattern. While ensuring the structural characteristics of the stitching area of ​​the chain teeth are straight and firm, it can also solve the problem of weak corner tension resistance caused by the "M"-shaped twill pattern.

DETAILED DESCRIPTION

[0024] The specific implementation of the embodiment of the present invention is described below with reference to the accompanying drawings.

[0025] Reference Figure 1 and Figure 2A high-tension zipper tape, the zipper tape 100 is interwoven with a plurality of warp yarns 111 and at least one weft yarn 112. The warp yarns 111 and the weft yarns 112 are both made of fiber aramid yarns. The zipper tape 100 is divided into a chain tooth stitching area 101, a rebound shrinkage area 102 and an M twill area 103 in the width direction. The chain tooth stitching area 101 adopts the warp yarns 111 floating on the weft yarns 112 and the weft yarns 112 sinking below the warp yarns 111, with one sinking and one floating. The warp yarns 111 float on the weft yarns 112 and the weft yarns 112 sink under the warp yarns 111, and are interwoven in a two-sinking and two-floating manner. The M twill area 103 adopts the warp yarns 111 float on the weft yarns 112 and the weft yarns 112 sink under the warp yarns 111, and are interwoven in a two-sinking and two-floating manner. After interweaving, the warp and weft yarns 112 in the M twill area 103 are arranged in an "M" shaped twill pattern.

[0026] Reference Figure 1 and Figure 2 The following high-tension zipper tape 100 is woven with sixty yarns and one weft yarn as an example. The warp yarn 111 and the weft yarn 112 are both made of aramid yarn with a specification of 200D or 300D. The specific weaving is as follows:

[0027] Reference Figure 2 The tooth stitching area 101, primarily used for stitching zipper teeth, is composed of twenty warp yarns 111 and one weft yarn 112 interwoven in a mixed pattern of one sinking and one floating and two sinking and two floating arrangements. Specifically, the interweaving pattern follows the order of one sinking and one floating, two sinking and two floating arrangements, one sinking and one floating, two sinking and two floating arrangements, one sinking and one floating, two sinking and two floating arrangements, and one sinking and one floating arrangement across the width of the zipper tape 100. The number of warp yarns 111 in each of the "one sinking and one floating" arrangements is two, and the number of warp yarns 111 in each of the "two sinking and two floating" arrangements is four. Furthermore, the warp and weft yarns 112 in the tooth stitching area 101, consisting of two sinking and two floating arrangements, form an "M"-shaped twill pattern. These warp and weft yarns 112 in the tooth stitching area 101 are located on the outermost sides and at the center corner of the "M"-shaped twill pattern.

[0028] The chain tooth stitching area 101 is made of an interlaced mixture of one sinking and one floating and two sinking and two floating structures. It not only has the characteristics of a one sinking and one floating structure such as being straight and firm, but also has a long floating structure of two sinking and two floating structures. The number of interlacing times is less, which can provide shrinkage space and facilitate the rapid shuttle of the chain tooth stitching to facilitate sewing the chain teeth to the chain tooth stitching area 101.

[0029] Reference Figure 2The rebound shrinkage zone 102 is formed by interweaving six warp yarns 111 and one weft yarn 112 in a two-sinking, two-floating pattern. The warp and weft yarns 112 in the rebound shrinkage zone 102 (along the width of the zipper tape 100) alternately sink and float, forming a planar pattern. This planar pattern, with its long-floating structure, minimal interweaving frequency, and alternating sinking and floating patterns, provides sufficient shrinkage space during the subsequent electric ironing, dyeing, and steaming processes of the zipper tape 100, thereby addressing the elastic shrinkage caused by these processes. Furthermore, the alternating sinking and floating patterns prevent the formation of bulging defects between the fastener elements and the twill zone 103 of the zipper tape 100.

[0030] Reference Figure 2 、 Figure 3 and Figure 4 , the M twill area 103 is interwoven by thirty-four warp yarns 111 and one weft yarn 112, wherein twenty-six of the thirty-four warp yarns 111 are interwoven in a two-sinking and two-floating manner to form a continuous "M"-shaped twill pattern, and two warp yarns 111 interwoven in a one-sinking and one-floating manner are inserted at the corners of each "M"-shaped twill pattern. The M twill area 103 of the present invention serves as the main body of the zipper tape 100, accounting for more than half of the composition of the zipper tape 100. It adopts two-sinking and two-floating to form a continuously curved and changing "M"-shaped twill pattern, and has extremely excellent stretchability and elastic structure. However, after experimental detection, as Figure 3 The corners of the ordinary "M"-shaped twill are weak in terms of tension resistance. In order to further improve the tension resistance of the zipper tape 100, the present invention inserts two warp yarns 111 interwoven in a sinking and floating manner at the corners of the "M"-shaped twill. The material of the warp yarns 111 is also made of fiber aramid yarn, so that the corners are frequently interwoven and the buckling is increased, further strengthening the tension resistance of the zipper tape 100 while ensuring clear texture.

[0031] Reference Figure 5 A high-tension zipper 10 includes a left zipper tape 11, a right zipper tape 12, two rows of zipper elements 13, a zipper pull 14, a U-shaped top stop 15, and a square latch 16. Both the left zipper tape 11 and the right zipper tape 12 are made of the high-tension zipper tape 100 of the present invention. The assembly of the left zipper tape 11, the right zipper tape 12, the two rows of zipper elements 13, the zipper pull 14, the U-shaped top stop 15, and the square latch 16 is substantially the same as the assembly of conventional zippers and will not be further described herein.

[0032] The above is only a specific implementation of the present invention, but the design concept of the present invention is not limited to this. Any non-substantial changes to the present invention using this concept shall be deemed as an infringement of the protection scope of the present invention.
