Embodiment

[0042] Spin 46tex yak cashmere / vinylon wrapped yarn on Parafil-1000 parallel spinning machine in Suessen, Germany, then use yak cashmere / vinylon wrapped yarn as core yarn, cashmere fiber as outer covering fiber, and install core yarn device 52.9tex cashmere / yak cashmere / vinylon core-spun yarn is spun on a QFA1528 spinning frame, and finally the fiber-removing technology is used to remove vinylon to obtain cashmere / yak cashmere core-spun yarn.

[0043] The manufacturing process is as follows:

[0044] In the first step, the yak cashmere fiber is subjected to the first fiber pretreatment, the first hair opening, the first blending and oiling, and the first carding to obtain the yak cashmere raw sliver; Yak cashmere roving is obtained after combing, second needle combing, first pre-roughing and first roving;

[0045] In the second step, the cashmere fiber is subjected to the second fiber pretreatment and the second wool opening treatment, and the treated cashmere fiber is subjec...

Abstract

The invention provides a production method for cashmere/yakwool covering yarns. Cashmere and yakwool fibers are respectively used to weave rough yarns in a wool spinning system. A parallel spinning method is used to weave yakwool/vinylon fascinated yarns by using yakwool rough yarns and vinylon filaments, and then the yakwool/ vinylon fascinated yarns are used as core yarns, and the cashmere rough yarns are used as wrapping yarns to weave the covering yarns, and finally, a vinylon dissolution technology is used to remove vinylon, to obtain excellent quality cashmere/yakwool covering yarns. Using the above technology, the cashmere fibers and yakwool fibers can be made into excellent quality covering yarns in high additional value. Especially in the first step and the second step, the yakwool fibers and the cashmere fibers respectively weave rough yarns on a wool spinning system, thereby reducing damages on fibers. In the third step, the parallel spinning method is used to weave the yakwool/vinylon fascinated yarns, thereby improving fluffiness and strength of the yarns. Using the production method, the yakwool just needs to be processed in rough yarns, and the method prevents a procedure in which processing of the yakwool is relatively difficult.

Description

technical field [0001] The invention relates to the field of novel yarns, in particular to a production method of cashmere / yak cashmere core-spun yarn. Background technique [0002] Cashmere is a thin layer of fine cashmere that grows on the outer skin of goats and covers the roots of goats' coarse hair. Cashmere fibers have irregular thin and deep curls, strong elongation, and excellent hygroscopicity. They are slender, light, soft, Slippery and warm all in one. Cashmere fibers are moderately strong, elastic and have a natural soft color. The fabric is comfortable and natural, and has good restoration properties, especially in the fact that it does not shrink after washing and has good shape retention. It is a high-grade clothing fabric. But its output is scarce, so it is called "soft gold". [0003] Yak cashmere is a layer of fine fluff growing from the bottom of the yak's coarse coat to resist the cold outside. my country is the main producing area of ​​yak down fiber...
