Problems solved by technology

These two fabrics are different from conventional polyester fibers because the fabrics have multiple components, and each component has a different dye absorption rate, which is prone to color difference and insufficient dyeing rate. At present, there are few researches on the dyeing process of conductive fibers and fabrics.

Description

technical field [0001] The invention relates to a dyeing method, in particular to a dyeing method of conductive polyester fiber. Background technique [0002] Polyester fiber fabrics have poor hygroscopicity, are extremely prone to static electricity, and are difficult to dissipate, which directly affects the production, processing and application of polyester fabric textiles, and even causes serious static electricity disasters. At home and abroad, a lot of research has been done on eliminating the static electricity of polyester fibers and their fabrics, and the preparation of conductive fibers and fabrics. The common method is to prepare conductive fibers by blending, add conductive agents to polyester chips, and obtain conductive fibers by melt spinning; Another method is to mix and weave polyester fiber and conductive metal wire to obtain a metal-wire-containing fabric, and the entire fabric has conductive properties due to the conductive effect of the metal wire. Thes...
