Abstract

The invention belongs to the field of preparation of composite conductive fibers and particularly relates to a preparation method of a copper sulfide / polyester composite conductive fiber. According to the method, firstly, polyester fibers are subjected to aminolysis, free amino groups exist on fiber surfaces, then copper sulfate pentahydrate and sodium thiosulfate are used as raw materials, and cuprous sulfide is produced on surfaces of the polyester fibers with a chemical reaction method. With the adoption of the method, adsorption of metal sulfides on the surfaces of the polyester fibers is effectively improved, and the method has the advantages that the preparation process condition is easy to implement, the cost is saved, the conductivity of the fiber is excellent and the like. The reaction condition is mild, required equipment is cheap, the production process is simple and lower in cost, besides, damage to strength, smoothness and the like of the fiber is smaller, and the fiber touches soft, is good in deformability, light in weight and good in processability, can be used for preparing various composite materials and has a lot of new applications in aspects of clothing, decoration, industry and the like.

Description

technical field [0001] The invention belongs to the field of composite conductive fiber preparation, in particular to a method for preparing copper sulfide / polyester 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 dur...
