Problems solved by technology

[0010] In the above two published patent documents, methods to reduce costs and maintain the excellent performance of spandex with high elasticity were explored from the two aspects of covering spandex with other types of yarn raw materials and the modification of spandex raw materials themselves. No method based on the original spandex raw materials From the improvement of knitting process, the yarn seeks to reduce the amount of spandex to reduce the cost, but at the same time maintain the elasticity of the fabric. Compared with the already very mature and popular spandex raw material yarn, this direction is more promising. The choice of market vitality and promotion

Embodiment 1

[0045] This embodiment provides a low-spandex high-elastic jacquard shoe upper sandwich fabric and a production method thereof. The low spandex and high elastic jacquard jacquard shoe upper sandwich fabric provided in this example contains 58% cationic modified polyester CDP, 37% nylon stretch yarn DTY and 5% 70D OP heavy mesh core spun yarn.

[0046] see figure 1 Schematic diagram of the bar configuration shown. The production method of the low-spandex high-elastic jacquard shoe upper sandwich fabric is as follows:

[0047] The JT02 type E24 double needle bed sheet jacquard jacquard 7-card warp knitting machine is selected as the production equipment, and the jacquard bar is set on the rear needle bed 1. The production method includes the following steps:

[0048] The yarn number of Jacquard bar is 0-0-2-2 / / weft-inserted weft, penetrated into normal temperature cationic light mesh + 70D spandex core-spun yarn;

[0049] A first common bar 21 is arranged on the inner side 10...

Embodiment 2

[0056] This embodiment provides a low-spandex high-elastic jacquard shoe upper sandwich fabric and a production method thereof. The low-spandex and high-elastic jacquard jacquard shoe upper sandwich fabric provided in this example contains 60% cationic modified polyester CDP, 38% nylon stretch yarn DTY and 2% 70D OP heavy mesh core-spun yarn.

[0057] The difference from Example 1 is that both L1 and L2 are penetrated into the white round cationic modified polyester CDP with light and room temperature, and the Jacquard bar is penetrated by nylon elastic yarn DTY+70D OP heavy mesh core-spun yarn. One common bar is threaded with white semi-gloss nylon stretch yarn DTY, the second common bar is threaded with nylon stretch yarn DTY+70D OP heavy mesh core-spun yarn, this low-spandex high-elastic jacquard jacquard upper sandwich fabric The production methods are all the same as in Example 1.

Embodiment 3

[0059] This embodiment provides a low-spandex high-elastic jacquard shoe upper sandwich fabric and a production method thereof. The low-spandex high-elastic jacquard jacquard upper sandwich fabric provided in this example contains 62% cationic modified polyester CDP, 35% nylon stretch yarn DTY and 3% 70D OP heavy mesh core spun yarn.

[0060] The production method of the low-spandex high-elastic jacquard shoe upper sandwich fabric is the same as that of Example 1.

Abstract

The invention belongs to the technical field of knitwear, and more specifically relates to a low-spandex high-elasticity jacquard shoe upper sandwich fabric and a production method thereof. The low-spandex high-elasticity jacquard jacquard shoe upper sandwich fabric contains 1-6% spandex by weight percentage, and the balance is any two of polyester, nylon and cationic fibers, and its production adopts double-needle bed sheet jacquard The warp knitting machine, wherein the jacquard bar is arranged on the rear needle bed, comprises the following steps: the lapping number of the jacquard bar is 0‑0‑2‑2 / / weft insertion; The inner side is provided with the first common comb, and the lapping number of the first common comb is 1-0-0-1 / / braiding chain organization; and the second common comb is set outside the Jacquard comb, The lapping number of the second common bar is 0‑0‑1‑1 / / . Compared with the process of using 10-20% spandex in high-elastic warp knitted fabrics in the prior art, the low-spandex high-elasticity jacquard jacquard shoe upper sandwich fabric provided by the present invention can reduce the cost by 33-50% while maintaining the fabric elasticity .

Description

technical field [0001] The invention belongs to the technical field of knitwear, and more particularly relates to a low-spandex high-elastic jacquard jacquard shoe upper sandwich fabric and a production method thereof. Background technique [0002] The elastic warp knitted fabric has the characteristics of large extensibility, good environmental protection, no wrinkle, soft and smooth hand feel, good elasticity, comfortable wearing, considerate fit, rich variety of colors and so on. Elastic warp knitted fabrics are divided into two-way (horizontal and longitudinal) elastic fabrics and unidirectional (longitudinal) elastic fabrics. The spandex filament content of the bidirectional elastic warp knitted fabric in the existing market is about 15-20%, which is mainly used for the production of swimwear, underwear, sportswear, etc.; the spandex filament content of the unidirectional elastic warp knitted fabric is about 5-10%. %, the obtained various spandex fabrics have comfortab...
