Composite filament of tencell, spun silk and modified synthetic fibers and preparation method thereof

Abstract

The invention provides a composite filament of tencell, spun silk and modified synthetic fibers and a preparation method thereof. The composite filament comprises a core layer (1), a middle fasciated layer (2) wound outside the core layer (1) and an outer fasciated layer (3) wound outside the middle fasciated layer (2), wherein the core layer (1) is made of mixed fibers of poly-p-phenylene benzobisthiazole fibers, the tencell and the spun silk; the fasciated layer (2) is made of the mixture of the spun silk and the tencell, and the content of the tencell is 50-70 percent by weihgt; and the outer fasciated layer (3) is made of the spun silk. The composite filament of tencell, spun silk and modified synthetic fibers not only can embody the good natural protein fiber performance of the spun silk, but also can maintain the excellent characteristics of the tencell and have stronger mechanical properties. Cloths made of the composite filament have the comfort of textiles of the spun silk, the strength of polyester fibers, the drapability of adhesive fibers and silk-like hand feeling, radiance, brilliance and skinny feeling, thus the composite filament has excellent properties.

Description

technical field [0001] The invention relates to a composite yarn prepared by an air-jet spinning method. 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 the application number 200310109049.2, although obtained certain effect, but, because prepared blended product, two ki...

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 for blending to carry out blending of above-mentioned two kinds of fibers, as the technology that the applicant discloses in the application number 200310109049.2, although obtained certain effect, but, because prepared blended product, two kinds of fibers are mixed in Together, they cannot fully reflect their respective advantages;

[0003] For this reason, the applicant has reported a kind of tencel-spun silk composite yarn in Chinese patent ZL. Too much reason, needs further improvement
