Novel fiber or textile cold piling chemical silvering method

Abstract

The invention provides a novel fiber or textile cold piling chemical silvering method. According to the method, natural fiber, chemical fiber or textiles are subjected to fiber surface treatment through room temperature piling; then, chemical silvering is adopted, so that the natural fiber, the chemical fiber or the textiles obtain good electrical conductivity and electromagnetic shielding function. The fiber or textiles prepared by the method provided by the invention have the advantages that the excellent and durable electrical conductivity and the electromagnetic shielding function are realized, the surface resistance is below than 4 omega/cm, the softness of the fiber fabric is not influenced, in addition, the comfort degree of the coating fiber fabric is greatly improved, the environment is protected, the economy is realized, the discharged pollution is little, and higher practical values are realized.

Description

Technical field [0001] The invention belongs to the technical field of surface plating of fibers and textiles, and specifically relates to a new method for cold pile chemical silver plating of fibers or textiles. Background technique [0002] For the currently known chemical plating technology for fibers and textiles, it is mainly applied to the surface of bulk materials. Using this process can make the surface of bulk materials obtain good conductivity and electromagnetic shielding function. There are also chemical plating processes for bulk materials used in artificial Fiber surface coating. Although this process can obtain metal coating on the surface of man-made fibers to make the fibers obtain conductivity and electromagnetic shielding functions, this technology has a large sewage discharge and uses a large number of national prohibited chemicals (nitric acid, acetone, etc.) and can only be used For special man-made fibers, it is difficult to use in mass production; with the...

[0002] For the currently known fiber and textile chemical plating technology, it is mainly applied to the surface of bulk materials. This process can make the surface of bulk materials obtain good conductivity and electromagnetic shielding function. Fiber surface coating, although this process can obtain metal coating on the surface of man-made fibers so that the fibers can obtain electrical conductivity and electromagnetic shielding function, but this technology discharges large amounts of sewage and uses a large number of nationally prohibited chemicals (nitric acid, acetone, etc.) and can only be used Due to special man-made fibers, it is difficult to be used in mass production; with the development of society, the demand for conductive and electromagnetic shielding fibers and fabrics in people's daily life and other fields is increasing. At the same time, the requirements for environmental protection make the existing silver plating process It is difficult to achieve mass production, so it is necessary to come up with improvements
