Surface copper-containing stainless steel fiber and its preparation process

Abstract

The invention provides a stainless steel fiber containing copper in the surface and a preparation method of the stainless steel fiber. The stainless steel fiber containing the copper in the surface comprises a plurality of stainless steel fiber rope strands which are tightly knitted in the twist direction. Each stainless steel fiber rope strand comprises a stainless steel alloy wire, a copper-plated layer and an iron pipe, wherein the copper-plated layer is arranged on the outer surface of the stainless steel alloy wire, the iron pipe wraps the copper-plated layer and the stainless steel alloy layer, and the iron pipe on the outermost layer of the stainless steel fiber containing copper in the surface is discomposed to expose the copper-plated layer. The stainless steel fiber containing copper in the surface has more excellent physical performance, the preparation process of conducting iron plating, bundle drawing, twisting and reductive acid separation is adopted after stainless steel alloy copper plating to prepare the stainless steel fiber containing copper in the surface, and the preparation process is simple.

Description

technical field [0001] The invention relates to the field of ropes, in particular to a copper-containing stainless steel fiber on the surface and a preparation process thereof. Background technique [0002] Stainless steel fiber is a new type of industrial material, which not only has high electrical conductivity, high thermal conductivity, high strength, high temperature resistance, corrosion resistance, etc., but also has the characteristics of chemical fiber and synthetic fiber; it is widely used in petroleum, chemical, chemical fiber, electronics, Textile, military, aviation, polymer materials, environmental protection and other industrial fields. The main production methods of stainless steel fibers are: monofilament drawing, cluster drawing, cutting method, and fusion method. Most of the manufacturers in the world that produce high-end products of high-strength ultrafine metal fibers on a large scale in the world today use the cluster drawing method. Stainless steel ...
