Composite silk and its preparing method

Abstract

This invention discloses one kind of lyocell - spun silk compound silk and its the manufacture method. This kind of lyocell - spun silk compound silk is make up of the core layer and the wrap round layer which enwind the core layer ; So called the core layer is lyocell silk or lyocell silk-spun silk synthetic fabric, the wrap round layer is spun silk; The lyocell- spun silk compound silk mentioned above can be manufactured by general air-jet spinning with two spray nozzles, the first spray nozzle and the second spray nozzle's pressure relations type is: N2=aN1+bkgf, a=0.5, b=0.35. This invention lyocell - spun silk compound silk, both can manifest the spun silk's fine crude protein textile fiber performance, and can maintain lyocell's eximious characteristic, uses this compound silk manufacture the lining, has spun silk textile's comfortableness, the polyester fiber's intensity, the gummy textile fiber's pendency performance, the silk's feel as well as the radiance, brightness and the bone feeling, are one kind of performance outstanding compound silk.

Description

technical field [0001] The invention relates to a composite yarn and a preparation method thereof, in particular to a tencel-spun silk composite yarn and a preparation method thereof by air-jet spinning. Background technique [0002] Tencel fiber is a pollution-free man-made natural fiber (refined cellulose fiber). Because the fiber has the comfort of cotton, the strength of polyester fiber, the drapability of viscose fiber, and the silk-like feel, brightness and vividness, it has been widely favored by people. Fabrics made from spun yarns tend to fluff more easily. Spun silk is a kind of protein fiber, which has excellent hand feeling and wearing comfort, but because of the relationship between length and fineness, it cannot be processed by pure cotton equipment. Therefore, many scientific and technical personnel adopt the method for blending to carry out blending of above-mentioned two kinds of fibers, as the technology that the applicant discloses in Chinese patent appl...

AI Technical Summary

Problems solved by technology

Spun silk is a kind of protein fiber, which has excellent hand feeling and wearing comfort, but because of the relationship between length and fineness, it has never been processed by pure cotton equipment

Therefore, many scientific and technical personnel adopt the method of blending to carry out blending of above-mentioned two kinds of fibers, as the technology that the applicant discloses in Chinese patent application number 200310109049.2, although obtained certain effect, but, because prepared blended products, two kinds of fibers Mixed together, can not fully reflect their respective advantages, so further improvement is still needed
