Problems solved by technology

Although the above method has a positive effect on improving the hygroscopicity of fibers, it cannot effectively solve the problems of static electricity and flame retardancy in polyester fibers. Therefore, it is important to develop new multifunctional polyester fibers with flame retardancy, antistatic and high hygroscopicity. significance

Abstract

The invention relates to a polyester fiber and a preparation method thereof. An oriented carbon nanotube bundle coated by polyethylene terephthalate and polyurea formaldehyde is mainly used as a raw material; and an oriented carbon nanotube bundle / polyester fiber coated by the polyurea formaldehyde is obtained through the spinning and the thermal stretching. The method has a simple operation process; the prepared polyester fiber contains rich hydrophilic radicals, and the interior thereof is a porous structure; and the polyester fiber has potential high moisture adsorptivity, flame retardance and antistatic performance.

Description

technical field [0001] The invention belongs to the field of polymer fiber preparation, and in particular relates to a polyester fiber and a preparation method thereof. Background technique [0002] In the past two decades, my country has made great progress in the chemical fiber industry, including polyester, nylon, spandex and other fiber varieties. The production technology is becoming more and more mature. Among them, polyester fiber is the most important and fastest growing fiber variety. Polyester fiber is usually Refers to polyethylene terephthalate fiber. [0003] Polyethylene terephthalate (PET) fiber has the advantages of high strength, good elasticity, good processing performance, excellent textile performance and wearing performance. It is the world's largest output and most widely used synthetic fiber variety, which can be used in Clothing, bedding, various decorative fabrics, special fabrics for national defense and other industrial fiber products, etc. [000...
