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.
At the same time, due to the lack of groups that can complex with copper ions on the surface of polyester fibers, it is impossible to directly prepare polyester conductive fibers by chemical reaction on the surface of fibers.

Abstract

The invention belongs to the field of preparation of composite conductive fibers and particularly relates to a preparation method of a cuprous sulfide / PET (polyethylene terephthalate) composite conductive fiber. According to the method, firstly, PET powder subjected to amination is used as a base body, copper sulfate and sodium thiosulfate are used as raw materials, nano cuprous sulfide is produced on the surface of the PET powder in an aqueous solution in situ, a nano cuprous sulfide / PET composite material is obtained, and then the nano cuprous sulfide / PET composite conductive fiber with lasting conductivity is prepared from the composite material in a melt spinning manner. According to the preparation technology of the conductive fiber, the conductive network is formed in the fiber, falling of a conductive layer is avoided during usage, the effect of the use environment is avoided, and the conductive function is lasting.

Description

technical field [0001] The invention belongs to the field of composite conductive fiber preparation, in particular to a preparation method of cuprous sulfide / PET composite conductive fiber. Background technique [0002] In recent years, with the rapid development and popularization of computers, telecommunications, microwave ovens, etc., the electromagnetic radiation in the living and working environment of human beings has become increasingly serious. The resulting electromagnetic wave interference has brought many negative effects on the normal operation of electronic equipment and human physical health. , In order to prevent electrostatic interference and electromagnetic wave interference, various antistatic and electromagnetic shielding materials have been developed for various purposes since the middle of the 20th century. In recent decades, the focus of research has shifted more to conductive fibers. The antistatic effect of conductive fibers is significant and durable...
