AI Technical Summary

Problems solved by technology

The fiber itself has long elongation at break, low breaking strength, and high moisture regain. If spinning is performed under improper humidity control, the fibers are easy to unite, and it is difficult to clean and roll, and it is difficult to card into a web, and it is easy to entangle the fibers. Due to the condition of each component, it is difficult to form a yarn, and the basic quality cannot be guaranteed

Embodiment 1

[0024] Take cotton / modal / Defroste processed into yarn as an example:

[0025] (1) Pretreatment is carried out to Defrostex fiber before spinning: the auxiliary agent that adopts is the antistatic agent of 1.5% and the adhesive agent of 0.2%; Static agent and adhesive agent, and stuffed for 12 hours to ensure the uniform penetration of auxiliary agents; the water content of Defrostex fiber is controlled at 10-12% during the spinning process.

[0026] (2) Modal and Defrostex fibers are weighed and mixed according to the mixing ratio of 1:1 dry weight;

[0027] In the cotton opening and cleaning process, the drum speed of the cotton opener is controlled at 600r / min, the needle beating hand is controlled at 800r / min, and the fan speed is increased by 20-30% to ensure the uniformity of the lap, increase the pressure at the lap, and increase the pressure on the cotton layer. The output area pretends to be an anti-dish unit for easy lap layering.

[0028] In the carding process, en...

Abstract

The invention relates to a method for processing fibers with high moisture absorption and release. The method comprises the following steps: (1) pre-treating Defrostex fibers before spinning; and (2)sequentially carrying out mixing, opening picking, cotton carding, drawing, roving and spinning on modal and the pretreated Defrostex fiber. The process is simple, the cost is low, the strength of processed Defrostex fiber yarns is high, the requirement of knitting and weaving is met, and the utilization range of the Defrostex product is further expanded.

Description

technical field [0001] The invention belongs to the field of functional fibers, in particular to a processing method for high moisture absorption and release fibers. Background technique [0002] Defrostex is an acrylic fiber developed by Japan's Toyobo Co., Ltd. It has the unique performance of long-term repeated moisture absorption and moisture release in response to environmental conditions, and has a high moisture absorption performance that is 3 times higher than wool / 5 times higher than cotton. The amazing moisture absorption and desorption speed and moisture absorption capacity of the fiber itself can reduce the discomfort caused by stuffiness and keep the clothes in a comfortable state. Because the fiber is a raw cotton structure composed of an inner core and an outer structure with different properties, the core is hydrophobic, and the outer part is high in moisture absorption and deodorization, and the functions of rapid moisture absorption and deodorization are re...
