Problems solved by technology

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, the hygroscopicity is poor, and the antistatic property is not good.
No flame retardant is added in the usual polyester preparation method or even if a flame retardant is added, most of them are halogen flame retardants. Toxic gas seriously endangers people's health

Abstract

The invention provides a conductive flame-retardant polyester, which is prepared from the following materials in parts by weight: 120 to 150 parts of tetrathiafulvalene-modified polyester fiber, 20 to40 parts of nitrogen-phosphorus-boron flame retardant, 10 to 15 parts of dispersant, 1 to 5 parts of p-toluenesulfonic acid and 20 to 30 parts of oxidant. Besides the excellent inherent properties ofpolyester material, such as high strength, good elasticity, good shape preservation property and high dimensional stability, the conductive flame-retardant polyester prepared by the invention has antistatic property and flame-retardant property, and therefore can be applied in fields, such as special clothing, having a broad application prospect.

Description

technical field [0001] The invention relates to the technical field of textile fibers, in particular to a conductive flame-resistant polyester and a preparation method thereof. Background technique [0002] Conventional fibers, especially synthetic fibers, tend to generate static electricity due to good electrical insulation during processing and use, which greatly limits their application fields. The conductivity of fibers can reduce or even eliminate electrostatic hazards, and can further expand the application fields of fibers. As an important functional material, conductive fibers will receive more and more attention. Commonly used conductive fibers are mainly made of inorganic conductive materials as conductive components by blending spinning or finishing. After the discovery of organic polymer conductive materials, especially polyaniline and its in-situ polymerization phenomenon, a new material and method for preparing conductive fibers is provided. The preparation ...
