A MANUFACTURE METHOD OF ELECTROCONDUCTIVE FIBER FOR ELECTRON-WAVE INTERCEPTION

摘要

A method for manufacturing electroconductive fibers for intercepting electron waves is provided to grant conductivity to various base fiber bodies, realize an antibacterial effect and an aesthetic appreciation effect, and effectively intercept electromagnetic waves. A base fiber body is etched by 50-100g/l of sodium hydroxide or 1%(v/v) of a surfactant at 60-80 deg.C for 5 minutes. The etched base fiber body is washed by water. The washed base fiber body is washed by a 10% hydrochloric acid solution for 20-50 minutes. The washed base fiber body is washed by water. The base fiber body is treated with a preliminary catalyst by a 7-12% hydrochloric acid solution. The base fiber body is deposited in a solution manufactured by adding 3N hydrochloric acid of a normal temperature to a mixture including 0.4 weight% of palladium chloride and tin chloride, at 20-50 deg.C for 10-30 minutes. The base fiber body is washed by water. The base fiber body is activated by a 13% sulphuric acid solution to activate electroless deposition eduction. The base fiber body is washed by water. The base fiber body is coated with a solution having pH 8.0-9.5, consisting of 10g/l of sulphuric acid nickel, 7.5g/l of sodium hypophosphite, 15g/l of sodium citrate, at 40-45 degrees. The coated base fiber body is washed by water. The base fiber body is treated with a pH 11.5-13.0 electroless copper chloride plating solution consisting of 2.3g/l of copper chloride, 9g/l of sodium hydroxide, 4g/l of formalin, and 0.125M of chelate. The treated base fiber body is washed to remove residual chemicals and alien substances. The base fiber body is dried.
