Problems solved by technology

[0005] Because the cyano group on the polyacrylonitrile fiber can complex with copper ions, the fiber has conductivity; and for the spandex fiber without cyano group, the conductive substance cannot complex with the fiber, thus affecting the spandex fiber to metal sulfur. The adsorption and adsorption fastness of the compound cannot be obtained, so it is impossible to obtain fibers with excellent electrical conductivity.

Abstract

The invention belongs to the field of preparation of composite conductive fibers and particularly relates to a preparation method of a cuprous sulfide/spandex composite conductive fiber. According to the method, firstly, polyurethane 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 polyurethane fibers with a chemical reaction method. With the adoption of the method, adsorption of metal sulfides on the surfaces of the spandex fibers is effectively improved. 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 / polyurethane 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. , To prevent electrostatic interference and electromagnetic wave interference. From the mid-20th century to the present, various antistatic and electromagnetic shielding materials have been developed for various purposes. In recent decades, the focus of research has shifted more to conductive fibers. The antistatic effect of conductive fibers is significant and dur...
