Description

The present invention relates to a warp-knit elastic woven fabric that does not roll, unravel, and recovers in the warp direction. The woven fabric has high recoverability, and is difficult to roll in the vertical, horizontal, or diagonal directions, and does not unravel. It has all the functional features that do not require arbitrary cutting and overlocking.

Currently, warp knitted fabrics are widely used as underwear, body nippers, sportswear and the like. Modern people are paying more and more attention to how to dress in a fashionable, unique and beautiful body. Therefore, clothes with memory function (excellent stretch recovery) are becoming more and more popular with the general public, and usually, the thinness of spandex improves the stretch recovery of the body nipper, but the disadvantage is There is a problem that curling and spandex are exposed. On the other hand, in the present invention, two reeds or multiple reeds are used to give the woven fabric excellent resilience and at the same time the curling and spandex are exposed. It alleviates the problem, and the woven fabric has an unrollable and unraveling effect, providing great room for development in the fields of underwear, body nippers and sportswear.

In order to aid the understanding of those skilled in the art, the present invention will be further described with reference to the drawings below.

As shown in FIG. 1, the present invention discloses a warp knitting elastic woven fabric that does not roll up, does not unravel, and has excellent recoverability, and the woven fabric body is woven by a single needle bed warp knitting machine. With a single needle bed warp knitting machine, BG1 adopts a double warp flat knitting structure to give a glossy effect to the exposed surface of the woven fabric, and GB2 adopts a spandex with a closed double knitting structure in the same direction. And it provides the woven fabric with important elasticity in the middle hidden in the woven fabric.

Adjust the needle density of the warp knitting machine to be used between 24 and 50 / inch, and use the following method for specific knitting:
1. 1. Warping of threads used in warp knitting:
1) Warping of synthetic filaments:
Model of warping machine: Karl Mayer DS 21/30 NC-2, thread is negative feed method.
Warping temperature: 23 ° C Warping humidity: 65%
In the workplace, process parameters are set under the above temperature and humidity conditions.
2) Spandex warping:
Model of warping machine: Karl Mayer DSE-H21 / 30 NC-2, thread is negative feed method.
Warping temperature: 24 ° C Warping humidity: 78%
In the workplace, process parameters are set under the above temperature and humidity conditions.

2. 2. Braiding work Model of warping machine: Karl Mayer HKS2-3, HKS4-1 or other single needle bed warping machine.
Model range: E28 to E50
The threading method is a full set.
The woven fabric uses two different types of yarn; FDY synthetic filaments and spandex.
For example, although the structural schematic diagram of the woven fabric is shown in FIG. 1, the synthetic fiber filament of GB1 adopts a double or triple warp flat knitting structure to give a gloss effect to the exposed surface of the woven fabric. The GB2 employs spandex with a double-knit structure with closed stitches in the same direction to provide important elasticity to the woven fabric in the middle hidden in the woven fabric.

3. 3. Dyeing arrangement Dry wash (or washing with water) → Preparation → Overflow dyeing → Dehydration → Finishing What should be explained is that the above is not a limitation on the technical method of the present invention, but is easy on the premise that it does not deviate from the idea of the present invention. All substitutions are within the scope of protection of the present invention.
