Problems solved by technology

[0002] Due to its good wearing comfort and body shaping performance, elastic knitted thermal fabrics are more and more popular and recognized by consumers, and it is one of the urgently needed products in the market; however, due to the late start of production of elastic knitted thermal fabrics, especially four-way stretch products , so many of its production processes are still in the exploratory stage. The process is mainly based on "high-temperature setting, dyeing, reduction cleaning, wool picking, finished product overfeeding, and high-temperature scalding" to complete the production of four-way stretch. This traditional process is due to The use of high temperature, strong acid, strong alkali and other conditions reduces the elasticity and service life of spandex. After repeated washing, the spandex will break and fall off, and the finished garment will not retain its shape at all; while low temperature setting, although the elasticity is greater, the garment will be damaged during production and wearing. During the process, due to the continuous shrinkage of spandex, the size of the clothes is severely reduced, which is not suitable for wearing

Embodiment 1

[0027] A production method of high shape retention elastic knitted warm fabric, comprising the steps of:

[0028] Woven fabric gray cloth→gray cloth opening→pre-setting→dyeing→pressing water drying cloth→grabbing→setting→scalding→shearing; the weaving method of the fabric gray cloth is as follows: the veil, the bottom yarn, the intermediate connecting yarn and the spandex yarn are passed through the weft Knitted gray fabric is produced by weaving, in which the face yarn is a blended yarn of cotton fiber and viscose fiber, the bottom yarn is DTY fine-denier polyester network low-elastic filament that has been steamed and shaped at a vacuum temperature of 130°C, and the intermediate connecting yarn is DTY polyester Network low elastic yarn, spandex yarn is 20D spandex yarn with 2.5 times of draft; the weaving diagram is as follows figure 1 As shown: the bottom yarn is the reverse side of the gray cloth weaving process, which is a loop structure, and the stitches are full of need...

Embodiment 2

[0044] The difference from Example 1 is that the veil is modal fiber.

[0045] The performance test results of the high shape retention elastic knitted thermal fabric are as follows:

[0046] 1. Elasticity: The elastic elongation in the warp direction is 52%, and the recovery rate is 93%; the elastic elongation in the weft direction is 145%, and the recovery rate is 92%.

[0047] 2. Shrinkage: After washing 10 times, the horizontal shrinkage is -2.8%, and the vertical shrinkage is -4.2%.

[0048] 3. Shape retention: After 12 washes, no spandex and other fibers were found to have damage such as melting and cracking, the size change was small, and the cloth surface hairiness was very little, achieving the purpose of high shape retention.

Embodiment 3

[0050] The difference from Example 1 is that the face yarn is a blended yarn of viscose fiber, wool fiber and long-staple cotton fiber.

[0051] The performance test results of the high shape retention elastic knitted thermal fabric are as follows:

[0052] 1. Elasticity: Warp elastic elongation is 55%, recovery rate is 95%; weft elastic elongation is 148%, recovery rate is 95%.

[0053] 2. Shrinkage: After washing 10 times, the horizontal shrinkage is -3.2%, and the vertical shrinkage is -3.8%.

[0054] 3. Shape retention: After washing for 15 times, no spandex and other fibers are found to have damage such as melting and cracking, the size changes are small, and the cloth surface hairiness is very small, achieving the purpose of high shape retention.

Abstract

The invention relates to a fabric production method, in particular to a method for producing a stretch knit warm fabric which is small in fiber damage, stable in elasticity, small in shrinkage degree and high in shape preservation property. The method comprises the steps of gray fabric knitting, gray fabric scutching, presetting, dyeing, water pressing and drying, fleecing, setting, lustring and shearing. During gray fabric knitting, ecotype fiber and single-component or multi-component blended yarn containing protein fiber or cellulosic fiber are used as surface yarn, DTY fine-denier polyester interlaced low-stretch long filament subjected to yarn steaming setting at 130 DEG C in a vacuum environment is used as bottom yarn, DTY polyester interlaced low-stretch yarn is used as middle connecting yarn, and 2.5 times drafting 20D spandex yarn is fed together with the surface yarn. In this way, the fabric is high in elasticity and shape preservation property. By reducing presetting temperature and machine speed, the degree of damage to spandex yarn is reduced to the minimum, and it is ensured that the elasticity of spandex yarn is stable.
