Abstract
The invention relates to a method for producing high-grade knitting yarns by blending of silkworm chrysalis protein fibers, bamboo fibers and cotton. After being processed by blowing, carding and pre-drawing, silkworm chrysalis protein fibers are in drawing with bamboo pre-drawing slivers and combed cotton slivers during the breaker drawing, and then are subjected to secondary drawing, roving, spinning and spooling, so that bobbins are produced. Fibers are wetted and oiled before being blown, so that flying and adhering caused by static electricity are reduced. Damages to the fibers during carding are reduced and the fibers are transferred smoothly. Since drawing delivery speed is reduced, and smoothness of bell-mouths and coiler pipe chutes is guaranteed, drawing delivery is smooth. During roving, yarn evenness is improved, and accidental stretching in rove unwinding is reduced. Yarn hairness is reduced, napping and piling resistance performance is good, and the clothes made of the yarns are light as silk, are elegant, soft, fine, smooth, breathable, skin friendly, environment friendly, bright in color, have breaking strength higher than that of silk fabrics of the same-type tissue structure, and have draping, wear resistance, bending stiffness and the like similar to those of the like silk fabrics.
Description
technical field [0001] The invention relates to a method for producing high-grade knitting yarn by blending silkworm chrysalis protein fiber with natural bamboo and cotton. Background technique [0002] Silkworm chrysalis protein fiber is a new type of biomass fiber made from high-quality protein PC extracted from silkworm chrysalis by comprehensive utilization of polymer technology, bioengineering technology and chemical fiber spinning technology, and blended with natural cellulose. In the process of processing, high-tech technology is used to enrich the protein on the surface of the fiber to form a protein fiber with a skin-core structure. Protein PC contains 18 kinds of amino acids, and the content of each amino acid is above 15mg / g. Among them, serine, threonine, tryptophan, tyrosine, etc. are very beneficial to human skin, which can maintain the activity of skin epidermal cells and delay skin aging. Oxidative aging. And the skin-core structure of the fiber can ensure ...
