Cotton fiber modification method

Abstract

The invention provides a cotton fiber modification method, which specifically comprises the following steps: immersing and heating cotton in a dehydroxylation agent, washing the soaked cotton with water, and finally drying the washed cotton. According to the cotton fiber modification method provided by the invention, the operation is simple, the used test dosage is small, the cost is low, the cotton treated by using the method provided by the invention is reduced-obviously in moisture regain, and is not easy to harden compared with untreated cotton, a cotton quilt made of the cotton is more light and comfortable, the shrinkage degree of cotton cloth woven by using modified cotton fiber is greatly reduced, and the method has a wide market application prospect.

Description

technical field [0001] The invention belongs to the technical field of textile materials, and in particular relates to a method for modifying cotton fibers. Background technique [0002] Cotton fiber is the fiber covered on the seeds of the Malvaceae cotton plant, also known as cotton, or cotton for short. The composition structure and physical and chemical properties of cotton fiber make the biggest advantage of cotton fiber is good spinnability. In addition, the main component of cotton fiber is cellulose, and there are a small amount of waxy substances, nitrogenous substances and pectin. Cotton fiber products also have good hygroscopicity and certain wear resistance, and the moisture regain rate reaches 6-10%. Under the humidity state, the strength of cotton fiber will increase by 8-12%. [0003] However, cotton fiber also has some disadvantages, such as poor strength when the humidity is too low. In addition, cotton fiber has strong hygroscopicity and a large shrinkage ...

AI Technical Summary

Problems solved by technology

Existing cotton fiber modification methods mainly include: 1. Multi-fiber compounding, that is, mixing multi-component fibers such as cotton fiber and hemp fiber, and optimizing the proportion to improve the hardening of cotton quilts. This method is relatively simple and convenient. However, it is possible to increase the cost of the product; 2. Silicone finishing. At present, the effect of this method on batch processing of cotton fibers is still inconclusive; 3. Using epoxy fluoropolymers to modify cotton fibers, the cost of this method is relatively high; 4. Bioenzyme modification, which has poor stability and high cost; 5. Nano-modification, that is, using nano-materials such as alumina, titanium dioxide, zinc oxide, and ceramic powder, by padding, implantation, or The coating method can carry out functional finishing on cotton fibers such as anti-ultraviolet, anti-bacterial and deodorizing, anti-infrared, anti-static, anti-electromagnetic radiation, far-infrared reflection and health care. This method provides a new method for the development of functional and high value-added cotton textiles. direction, but the process is more complicated
