Problems solved by technology

However, polyester fiber is a typical hydrophobic fiber with a moisture regain of only 0.4%. As a material for personal wear, its wearing comfort is very poor. In high humidity and high temperature conditions, people wearing synthetic fiber clothing will feel stuffy. Irritable mood; in the hot and humid state, the friction between the human body and the clothes increases, and the feeling of heaviness increases, which has little impact on people's psychological and physiological changes
At the same time, the hydrophilicity of polyester fiber is very poor, which also brings a series of problems to weaving.
Such as easy to accumulate static electricity, easy to absorb dust, difficult to remove oil stains, etc.

Abstract

The invention relates to a preparation method and application of a high-performance coconut shell adjuvant. The preparation method of the high-performance coconut shell adjuvant is characterized by comprising the following specific steps: (1) raw material pre-treatment; (2) carbonizing treatment; (3) aging modification: performing aging modification treatment on modified coconut shell powder at the step (2) to obtain compound coconut shell powder; and (4) high-performance coconut shell adjuvant: coating a chitosan material as a shell layer over the compound coconut shell adjuvant as a core layer to prepare the high-performance coconut shell adjuvant containing the compound coconut shell powder. The prepared high-performance coconut shell adjuvant is applied to polyester fibers, composite polyester fibers, nylon lace fabrics and polyester films.

Description

【Technical field】 [0001] The invention relates to the technical field of textile production, in particular to a preparation method and application of a high-performance coconut shell additive. 【Background technique】 [0002] Since polyester and polyester fiber entered large-scale industrialization in the 1970s, the development speed is much faster than other synthetic materials and synthetic fibers. In 2010, the output of polyester fiber in my country was 25.13 million tons, accounting for about 81% of my country's chemical fiber output; It accounts for about 70% of the world's polyester fiber production. In the next 10 years, the world's polyester and polyester fiber will still maintain a growth rate of more than 3%, and polyester fiber will account for more than 60% of the world's total fiber products. The physical and mechanical properties of polyester fibers such as strength, abrasion resistance, resilience and dimensional stability can better meet the needs of various u...
