Description

A flexible conductive fabric with flame-retardant and hydrophobic effect

technical field

The utility model relates to the field of functional textiles, in particular to a flexible conductive fabric with flame-retardant and hydrophobic functions.

Background technique

As early as 60 years ago, various new fibers free from natural fibers were continuously developed, among which conductive fibers received great attention because of their electrical conductivity. According to the characteristics of conductive fibers, it can be divided into metal-based conductive fibers, carbon black-based conductive fibers, conductive polymer fibers, and metal compound-based conductive fibers. Conductive fabrics are made by blending conductive fibers and clothing fibers or carrying conductive materials on the basis of clothing fabrics. As a functional fabric, conductive fabric can be widely used in antistatic textiles, electromagnetic wave shielding textiles, anti-reconnaissance camouflage materials and smart wearable textiles, which greatly expands the application fields of textiles and clothing.

Although conductive fibers have been greatly developed, there are still certain problems, such as metal-based conductive fibers have a bad hand feel, poor cohesion, excessive weight and are not easy to blend; carbon black-based conductive fibers have poor impact resistance and are easy to break; Polymer fibers are too rigid, insoluble, infusible, and difficult to form; metal compound-type conductive fibers feel rough and have poor comfort. Therefore, the conductive fabric blended with conductive fiber and clothing fiber has various defects, and the research on loading conductive materials on the clothing textile as the base is more extensive.

With the development of society, people have more and more demands for multifunctional protective clothing, such as antibacterial/antistatic fabrics, antistatic/hydrophobic and oleophobic fabrics, etc. However, at present, the functions of various functional finishing agents are relatively single, and there are compatibility problems among the single-functional finishing agents. Some are difficult to use in the same bath, and some are difficult to meet the corresponding requirements even if they are treated step by step. At present, there are still few studies on flexible conductive fabrics with flame-retardant and hydrophobic properties.
