Problems solved by technology

[0003] Ordinary spun cotton adopts a three-layer structure, and the upper and lower surface layers of polyester are bonded with hollow cotton in the middle. Although the thermal insulation effect is good, it is not suitable for today's fashionable cold-proof clothing. When silk cotton is used, its anti-deformation ability is poor, and the clothes will be deformed and wrinkled after several times of washing, which greatly affects its aesthetics

Abstract

The invention discloses an anti-deformation spun cotton processing and production technology. The anti-deformation spun cotton processing and production technology includes the following steps of selecting polyacrylonitrile fibers, polyester staple fibers, ES fibers and a cotton material as raw materials; washing, mixing, chopping, sterilizing and drying the polyacrylonitrile fibers, the polyesterstaple fibers and the cotton material, and matching the polyacrylonitrile fibers, the polyester staple fibers and the cotton material according to a mass ratio, wherein the polyacrylonitrile fibers accounts for 5%-15%, the polyester staple fibers account for 5%-15%, the cotton material account for 55%-85%, and the ES fibers account for 5%-15%; doping the dried raw materials with 1%-2% of the ES fibers, placing the mixture into a screw extrusion machine to make the mixture melted and form a melt, and conducting extrusion through a screw. By adopting the anti-deformation spun cotton processingand production technology, the bulkiness, compression-resilience property, heat retention property, strength and washing resistance of spun cotton are improved, the thickness and the weight are reduced, and thus the spun cotton is suitable for filling the interiors of various winter cold protective clothing and home textiles; the production technology is simple, and meanwhile, the production costis greatly reduced, so that large-scale production is facilitated.

Description

technical field [0001] The invention specifically relates to a processing technology for spun cotton, in particular to a processing and production technology for preventing deformation of spun cotton. Background technique [0002] The so-called spun cotton production line is to mix chemical fiber adhesive fibers with low melting point into pure cotton or chemical fiber cotton sheets. The cotton sheets obtained by bonding chemical fiber cotton together, and the hot-melt quilt is made of hot-melt cotton sheets according to the quilt standard. [0003] Ordinary spun cotton adopts a three-layer structure, and the upper and lower surface layers of polyester are bonded with hollow cotton in the middle. Although the thermal insulation effect is good, it is not suitable for today's fashionable cold-proof clothing. When silk cotton is used, its anti-deformation ability is poor, and the clothes will be deformed and wrinkled after several washings, which greatly affects its aesthetics...
