Problems solved by technology

Coarsening treatment is not only a complicated process, but also produces more pollution
[0005] The main problem facing the metal coating at present is that the bonding force with the surface of the polyester fiber is poor and it is easy to fall off
This is because PET is a symmetrical straight chain macromolecule, the molecular chain does not contain side chain groups, the regularity is very good, the crystallinity is high, and the structure lacks high polar groups; it can improve the bonding fastness of the metal coating. come difficult

Abstract

The invention relates to a conductive fabric and a preparation method thereof. The conductive fabric is composed of a modified polyester industrial silk fabric and a copper plating layer coated on the silk fabric. The material of modified polyester industrial yarns is modified polyester, and the modified polyester is composed of polyester and amino fatty acid glycol ester; under a certain temperature condition, the increasing range of free volume of the amino fatty acid glycol ester is much greater than that of polyester macromolecular chain, so that the interfacial combined functions of the metal coating and polyester fibers are improved, and the wash fastness of the metal coating is improved. Meanwhile, the regularity and crystallization of polyester structure are not destroyed, and the good performance of polyester is maintained. The conductive fabric is widely used in the field of clothing, electronic industry, medical science, biological science, aerospace and the like.

Description

technical field [0001] The invention belongs to the technical field of fiber modification, and relates to a conductive fabric and a preparation method thereof. Background technique [0002] Since its appearance, polyethylene terephthalate (PET) fiber has developed rapidly because of its excellent performance, and its output has become the crown of synthetic fibers in the world. Polyester fiber has a series of excellent properties such as high breaking strength and elastic modulus, moderate resilience, excellent heat setting, good heat resistance and light resistance, acid resistance, alkali resistance and corrosion resistance, and the fabric has the advantages of wrinkle resistance and good stiffness. Ester fiber is widely used in clothing, industrial yarn and other fields. [0003] With the rapid development of electronic technology, more and more electronic products and equipment are used in people's production and life, and most electronic products such as microwave oven...
