Problems solved by technology

Compared with ramie fiber that can be spun by single fiber, the length of hemp single fiber is short (generally 7-20mm), and the length uniformity of process fiber is worse. In the process of spinning hemp fiber yarn products with cotton spinning system, It will inevitably cause a large amount of hemp fiber to become tow, and the processing efficiency is very low
At this stage, there are patents proposing that the pure spinning count of hemp produced by cotton-type spinning equipment is 40 s Left an

Abstract

The invention provides a processing method of yarn for hemp/cotton blended high-grade underwear fabric. The processing method is characterized by comprising the steps that hemp fibers and cotton fibers are pretreated respectively, the pretreated hemp fibers and the pretreated cotton fibers are blended, and then the blended fibers are subjected to cotton opening and scutching, cotton carding, combing, drawing, roving and spinning in sequence. The processing method solves the problem that high-count hemp blended yarn is difficult to produce, the count of the hemp/cotton blended yarn is increased to 70 S-120 S, and the requirement for producing the hemp/cotton blended high-grade underwear fabric is met.

Description

technical field [0001] The invention belongs to the textile field, and relates to a hemp / cotton blended high-grade underwear fabric yarn and a processing method. Background technique [0002] Hemp (also known as hemp) has the characteristics of strong adaptability during planting and growth, no pests and diseases, no need to spray pesticides and fertilization, and is a new type of pure natural green fiber resource. Because hemp fiber also has the characteristics of good moisture absorption and perspiration performance, strong antibacterial and bactericidal effect, soft fit without itching, strong antistatic ability, etc., it is an ideal skin-adhering fiber material. [0003] However, at present, most hemp yarn products are still in the middle and low grades, which cannot meet the needs of high-grade underwear fabrics. The main reason is that the hemp fiber is a technical fiber with poor fiber length uniformity, high rigidity, brittleness and hardness, and poor cohesion. Ro...
