Problems solved by technology

[0003] However, due to the tight arrangement of the internal molecules of polyester and the lack of a hydrophilic structure between the molecules, the moisture regain is very small and the hygroscopicity is poor.
Under the condition of a relative humidity of 95%, its highest moisture absorption rate is 0.7%. Due to its poor hygroscopicity and poor resistance, polyester fabrics have poor air permeability, poor dyeability, and poor pilling resistance.

Abstract

The invention relates to a far-infrared and antistatic polyester functional fiber with good moisture absorption. Polyester is used as a base for the far-infrared and antistatic polyester functional fiber, carbon nano-tubes, ZrO2 nano-particles, TiO2 nano-particles, talc powder and dispersing agents are used as fillers for the far-infrared and antistatic polyester functional fiber, and the far-infrared and antistatic polyester functional fiber is prepared from the base and the fillers by means of melt spinning.

Description

technical field [0001] The present application relates to the technical field of polyester fibers, in particular to a polyester functional fiber with far-infrared, antistatic and good hygroscopic properties. Background technique [0002] Polyester fiber is a fiber-forming high-polymer fiber made from purified terephthalic acid (PTA) or dimethyl terephthalate (DMT) and ethylene glycol (EG) through esterification or transesterification and polycondensation reactions. Polyethylene terephthalate (PET), also known as polyester, is an important variety of synthetic fibers. Polyester fiber has excellent properties, such as high breaking strength and elastic modulus, moderate resilience, excellent heat setting performance, good heat resistance, good resistance to organic solvents and washing resistance, good corrosion resistance, good The stability of acid and weak alkali, the clothes woven from it are durable, have good electrical insulation, are easy to wash and dry quickly, and ...
