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 o

Embodiment 1

[0062] The present embodiment provides a kind of technique of producing high elastic flat knitting machine product, comprises the following steps:

[0063] (1) Yarn preparation: 42D low-temperature polyolefin elastic fiber is selected as the core yarn of the core-spun yarn. The finishing temperature of the dimensional stability of the polyolefin elastic fiber is 85°C. The leather yarn of the core-spun yarn is selected to be environmentally friendly and biologically The degraded wool fiber is 100% purely spun, and the roving is made on the wool spinning equipment, and then the draft ratio of the core yarn is set to 2.0 times on the spinning frame, and the core-spun yarn is spun according to the twist coefficient of the normal sweater yarn. A spun yarn with a yarn count of 19s was obtained, the weight ratio of the wool fiber in the whole core-spun yarn was 93%, and the weight ratio of the low-temperature polyolefin elastic fiber was 7%. The spun yarn is plyed through a two-for-o...

Embodiment 2

[0067] The present embodiment provides a kind of technique of producing high elastic flat knitting machine product, comprises the following steps:

[0068] (1) Yarn preparation: 33D low-temperature polyolefin elastic fiber is selected as the core yarn of the core-spun yarn. The finishing temperature of the dimensional stability of the polyolefin elastic fiber is 100°C. The leather yarn of the core-spun yarn is selected to be environmentally friendly and bio The degraded corn fiber is 100% purely spun, and the roving is made on the cotton spinning equipment, and then the draft ratio of the core yarn is set to 2.5 times on the spinning frame, and the core-spun yarn is spun according to the twist coefficient of the normal sweater yarn. A spun yarn with a yarn count of 55s was obtained, the weight ratio of corn fiber in the whole core-spun yarn was 88%, and the weight ratio of low-temperature polyolefin elastic fiber was 12%. The spun yarn is plyed through a two-for-one twister, a...

Embodiment 3

[0072] The present embodiment provides a kind of technique of producing high elastic flat knitting machine product, comprises the following steps:

[0073] (1) Yarn preparation: choose 75D low-temperature polyolefin elastic fiber as the core yarn of the core-spun yarn. The finishing temperature for the dimensional stability of the polyolefin elastic fiber is 130°C. The leather yarn of the core-spun yarn is selected to be environmentally friendly and bio- The degraded modal fiber is 100% purely spun, and the roving is made on the cotton spinning equipment, and then the draft ratio of the core yarn is set to 2.5 times on the spinning frame, and the core-spun yarn is spun according to the twist coefficient of the normal sweater yarn. The spun yarn with a yarn count of 20s is obtained, the weight ratio of modal fiber in the whole core-spun yarn is 90%, and the weight ratio of low-temperature polyolefin elastic fiber is 10%. The spun yarn is plyed through a two-for-one twister, and...

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 ...
