Problems solved by technology

[0003] Cashmere is much thinner than wool, and the outer scales are also finer and smoother than wool. Therefore, it is light in weight, soft, and has good toughness. It is especially suitable for making underwear. Most of the cashmere sweaters made are prone to pilling. Once pilling occurs, the aesthetics of the cashmere sweater will be affected. At the same time, cashmere resources are limited, and cashmere products are very expensive;
[0004] Wool-like fabrics are widely accepted in the current market, but there are some problems in the preparation methods of wool-like fabrics. The wool fiber for preparing wool-like fabrics is too fine, the density is low, and the softness is low, and the body comfort is poor.

Abstract

The invention discloses a preparation method of a high-density wool-like fabric. The preparation method comprises the following steps of raw material preparation: preparing synthetic fibers from a copolymer of a first monomer, a second monomer and a third monomer, the first monomer being acrylonitrile, and the addition amount of the first monomer being 85-90%; spinning preparation: uniformly mixing the synthesized fibers with cotton fibers, silk fibers and jute fibers, then extruding the high-temperature molten mixture through a screw, filtering and extruding through spinneret orifices, the wool-like fabric prepared by the preparation method has the advantages of no hair slip, no pilling and high wool fiber density, the fabric is soft and good in bulkiness, good in somatosensory comfort and less in fuzzing and pilling phenomena, can be processed into a blanket or an artificial fur, and has characteristics of smooth and beautiful surface due to adding the cotton fiber, the silkworm fiber and the hemp fiber, such that the air permeability is improved, and the toughness is enhanced.

Description

technical field [0001] The invention relates to the technical field of fabric preparation, in particular to a method for preparing a high-density wool-like fabric. Background technique [0002] Wool has always been loved by consumers, but wool is expensive, and the fabric shrinks a lot after washing, while acrylic fiber is widely used in clothing, various decorations, and industrial fields because of its wool-like appearance and low cost; [0003] Cashmere is much thinner than wool, and the outer scales are also finer and smoother than wool. Therefore, it is light in weight, soft, and has good toughness. It is especially suitable for making underwear. Most of the cashmere sweaters made are prone to pilling. Once pilling occurs, the aesthetics of the cashmere sweater will be affected. At the same time, cashmere resources are limited, and cashmere products are very expensive; [0004] Wool-like fabrics are widely accepted in the current market, but there are some problems in ...
