摘要：
Coupling elements of a slide fastener are immersed in an acidic treating liquid containing hydrogen peroxide, sulfuric acid, phosphoric acid, a surfactant, and an aliphatic alcohol to effect acid treament to smooth the outer surfaces of the coupling elements. The acid-treated outer surfaces of the coupling elements of the slide fastener or stringer thereof may be further subjected to rustproofing coating or plating.
