Anti-electrostatic nano compound polyester fibre and making method thereof

Abstract

The invention relates to an antistatic nanocomposite polyester fiber and a preparation method. The fiber is ternary blended melt-spun polyester or modified polyester, accelerator and nanometer powder. Wherein the accelerator is the condensation product of m-benzene-containing copolyester and polyethylene glycol, which can effectively improve the dispersion of nano-powder in polyester or modified polyester, and has antistatic synergistic effect; nano-powder is Metal oxides with good electrical conductivity. This kind of nanocomposite fiber has high mechanical properties and good antistatic effect, and can play a huge role in the fields of civil and industrial fabrics.

Description

technical field

[0001] The invention relates to an antistatic nanocomposite polyester fiber and a preparation method. The fiber is made of polyester (PET) or modified polyester, accelerant and nano-powder by ternary blending and melt-spinning. The accelerator is the condensation product of m-benzene-containing copolyester and polyethylene glycol (PEG), which can effectively improve the dispersion of nano-powder in polyester or modified polyester, and has antistatic synergistic effect; The powder is a metal oxide with good electrical conductivity. The nanocomposite fiber has high mechanical properties and good antistatic effect. Background of the invention

[0002] Polyester fiber is the most widely used synthetic fiber, but due to its dense crystal structure and low moisture absorption capacity, it leads to the accumulation of static charge, which brings inconvenience to production and use, so the antistatic modification of polyester fiber has been is a research hotspot. ...
