Process for producing high-elasticity flat knitting machine product

Abstract

The invention discloses a process for producing a high-elasticity flat knitting machine product. The process comprises the following steps of (1) yarn preparing, namely selecting core yarn fibers, selecting skin yarn of covering yarn, spinning rough yarn of the selected skin yarn, finishing spinning of spun yarn of the covering yarn, stranding by a two-for-one twister, and spooling to obtain a yarn raw material for flat knitting machine production; (2) feather piece weaving and sewing; and (3) ready-made clothes water washing after-finishing, namely carrying out first-pass in-vat water washingon the ready-made clothes, then taking out of the vat and dehydrating, adopting a special ready-made clothes elastic shaping process, taking the ready-made sweater into a vat after taking out of a furnace, adding a softening agent into normal-temperature water to carry out hand feeling finishing, and then taking out of the vat and dehydrating, drying and ironing to obtain the finished ready-madeclothes. According to the process for producing the high-elasticity flat knitting machine product, non-spandex covering yarn serves as a raw material and is combined with a ready-made clothes washingafter-finishing process and a process of weaving on a flat knitting machine, and the obtained non-spandex high-elasticity sweater is stable in shrinkage rate and excellent in elasticity and elastic recovery rate.

Description

technical field [0001] The invention relates to the technical field of textile flat knitting sweater manufacturing, and more specifically relates to a process for producing high-elasticity flat knitting products. Background technique [0002] Sweaters have always been favored by enterprises and consumers because of their natural elasticity formed by their own organizational structure, unique style, rich styles, and quick response to meet market demand. However, sweaters will shorten, lose elasticity and deform after wearing for a long time. Consumers struggle to restore their elasticity and come up with various methods, but the effect is not very good. The main reason is that the particularity of the sweater production method limits the elastic raw materials. usage of. [0003] As we all know, the high elasticity and elastic recovery rate of ready-made clothing mainly depend on the elastic fiber material in the fabric, and the elastic fiber used in traditional high-elastic ...

AI Technical Summary

Problems solved by technology

The production of high-elastic sweaters lacks this high-temperature setting process between the cloth piece and the finished garment. As a result, elastic fibers such as spandex cannot be used when choosing sweater materials, so as not to make it difficult to ensure the shrinkage and curling of high-elastic sweaters. and dimensional stability requirements

[0004] In the existing technology, there is a method of plying single yarns into high-twist strands to improve elasticity by using the method of co-twisting, but the high-twist sweater feels too hard and will cause torsion pieces; The spandex core-spun yarn is first woven, and then the garment is made of elastic sweaters by high-temperature mold ironing, but the dimensional stability and shrinkage of the whole batch of goods are difficult to stabilize during mass production; there are also non-drawing, non-core-spun The way of plying single yarns with different boiling water shrinkage to improve elasticity, but because of the use of polyester filaments that need to be dyed at high temperature, it is difficult to solve the dyeing problem in large-scale production, and because the spinning method uses black and white With drafting and non-core-spun methods, the elasticity and elastic recovery rate of the finished sweater are also relatively small, far inferior to the high elasticity of spandex. At the same time, polyester products are chemical fibers that cannot be biodegraded, which is not conducive to sustainable development of the environment.
