FIBER FOR CHEMICAL PLATING AND PRODUCTION THEREOF

摘要

PURPOSE:To obtain a fiber which can be plated by chemical plating without pretreatment by coating the surface of a fiber with a coating film of an insolubilized hydrophilic polymer containing palladium or silver in the form of ion or colloid. CONSTITUTION:A mixed aqueous solution of a hydrophilic polymer or a water- soluble polymer containing palladium or silver in the form of ion or colloid and a water-soluble palladium or silver compound is as necessary added with a reducing agent and a crosslinking agent for said water soluble polymer to obtain a treating liquid. The liquid is applied to the surface of a fiber or to a specific part of a fiber aggregate and insolubilized to obtain the objective fiber for chemical plating or a fiber aggregate having a specific part which can be plated by chemical plating. A fiber aggregate which can be plated by chemical plating exclusively on a specific fiber is produced by blending fibers having the above coating film with fibers free from the coating film.
