Preparation method of natural degradable covering yarn

Abstract

The invention belongs to the field of spinning, and particularly relates to a preparation method of natural degradable covering yarn. The preparation method comprises the following steps: preparation of a core wire: blending jute fibers, plying and twisting to obtain a mixed spinning fiber, infiltrating the mixed spinning fiber in gelatinized starch slurry, taking out the mixed spinning fiber, aging at room temperature to obtain a core wire coarse fiber, rapidly infiltrating the core wire coarse fiber in a zein solution, taking out the core wire coarse fiber, and drying the core wire coarse fiber at room temperature to obtain the core wire; primary coating: winding and wrapping polylactic acid fibers and cotton fibers outside the core wire in parallel to achieve primary coating, and thus forming a yarn core; and secondary coating: coating the yarn core with bamboo fiber slivers, and carrying out secondary coating to obtain the natural degradable wrap yarn. The wrap yarn prepared by the preparation method disclosed by the invention has good flexibility, elasticity and obdurability; the adopted raw materials are all natural and degradable raw materials; and the raw materials are low in cost and can be effectively used for producing disposable fabric.

Description

technical field [0001] The invention belongs to the textile field, in particular to a preparation method of a natural degradable covered yarn. Background technique [0002] Covered yarn, also known as wrapping yarn, is a new type of yarn structure, which is formed by using filament or short fiber as the core and wrapping another filament or short fiber sliver. Generally speaking, the outer covering yarn wraps the yarn core in a spiral manner, which is characterized by uniformity, fluffiness and plumpness, smooth yarn with less hairiness, high strength, and less broken ends. Compared with ordinary yarns, it has a very Stable structure and more excellent performance. [0003] The existing covered yarns are mostly used for knitted fabrics requiring high elasticity, and some are used for woven fabrics. They are ideal yarns for high-grade thin wool and linen fabrics, jacquard double-layer weft-knitted fabrics and warp-knitted fabrics. Covered yarns can be spun for both thick an...

AI Technical Summary

Problems solved by technology

[0006] In order to solve the problems that the existing covered yarns have relatively high chemical fiber components and raw materials, most of the covered yarns are not degradable, and the raw materials of the existing covered yarns are expensive and difficult to be used in the preparation of disposable fabrics. The present invention provides A preparation method of natural degradable covered yarn
