Problems solved by technology

However, due to factors such as market price and material performance of raw materials such as nylon and polyester, their products gradually cannot meet market requirements. In addition, the initial white blank yarn made of viscose filament and nylon needs to go through a second dyeing process. Viscose fiber and nylon are colored separately, and then processed into knitted garments by flat knitting machine or circular knitting machine. The process is relatively complicated and the process requirements are also high.

Embodiment 1

[0042] A new type of composite yarn, the composite yarn is made of viscose fiber and polytrimethylene terephthalate fiber on a twisting machine or a covering yarn machine, twisted and plyed to make a white yarn, and then passed through It is made by pre-treatment, dyeing, washing, softening and finishing. The poly(trimethylene terephthalate) fiber refers to a compound polyester fiber obtained by esterification and polycondensation of terephthalic acid and 1,3-propanediol.

[0043] A kind of manufacture method of novel composite yarn is realized by following steps:

[0044] a: Twisting and plying; twisting and plying viscose filaments and polytrimethylene terephthalate fibers on a twisting machine or a covered yarn machine to make white blank yarn;

[0045] b: Pre-treatment, immerse the white blank yarn made in step a above into soft water at normal temperature, and add 0.5 g / L of cleaning agent and 1 g / L of soda ash according to the volume of soft water in the soft water at n...

Abstract

The invention discloses the new pattern composite yarn and making method, comprising the following steps: putting cellulose viscose and polyytrimethylene terephthalate fibre into twine machine or lapping yarn machine, carrying out twisting and ply doubling, making white yarn, then carrying out fore treatment, coloring, cleaning, soft finishing, and getting product. The cloth has good tension, rebound elasticity, crease-shedding effect, ventilating, absorbing sweat effect, and dyeing behaviour, resistance to ultraviolet radiation and static electricity effect. The method has the advantages of low cost.

Description

technical field [0001] The invention relates to a kind of yarn, and mainly relates to a manufacturing method of a novel composite yarn. Background technique [0002] At present, the production of viscose fiber and even chemical fiber industry is seriously greater than the demand, coupled with the serious shortage of the development of its downstream products, many products are already in recession, and the market space is gradually decreasing. Take the curved bead yarn product that has contributed the most to the viscose industry as an example. The curved bead yarn is a stitching technology introduced from abroad in the 1990s. For about 10 years, this variety generally uses viscose filament (generally 120D, 150D with or without light, etc.) and nylon (generally 70D) to twist on a twisting machine or a covered yarn machine. Ply, and finally make a composite yarn. Nylon has good elasticity and plays a solid skeleton role in clothing, while viscose fiber plays the main role o...
