Problems solved by technology

[0006] However, in order to achieve antistatic, negative ion and other functions, the above fibers have added a large amount of modifying additives, which affects the textile performance of polyester resin chips, thus failing to meet the requirements of ultrafine denier fibers.

Abstract

The invention provides a method for preparing ultraviolet-resistant and antistatic superfine-denier polyester fibers. The method includes adding trace sericite, iron oxide and natural tourmaline into polyester resin slices. The method has the advantages that the superfine-denier polyester fibers prepared by the aid of the method are excellent in ultraviolet resistance and antistatic and anionic properties; the method is low in cost, and good modification effects can be realized; large quantities of chemical preparations are omitted in integral preparation procedures, and accordingly the method is an environment-friendly novel method for preparing fibers.

Description

technical field [0001] The invention relates to the field of functional clothing fabrics, in particular to a method for preparing ultrafine denier polyester fibers with anti-ultraviolet rays and anti-static properties. Background technique [0002] As the most widely used chemical fiber, polyester fiber has good fiber-forming and mechanical properties, high strength, good light resistance, heat resistance and acid and alkali resistance, good processability and spinnability, and can be purely spun or blended and interweave. Polyester fabrics are washable, wear-resistant, non-ironing and wrinkle-resistant, and are widely used in clothing, home textiles, decoration and product applications. However, polyester fiber also has disadvantages such as poor hygroscopicity, non-sweat-absorbing fabric, stuffy feeling when worn, anti-ultraviolet performance, poor anti-static ability, and easy to be stained with dust, which greatly restricts the application and development of polyester f...
