Document Type and Number:
WIPO Patent Application WO/1995/016809
Kind Code:
A1
Abstract:
In knitting parts (platine, guide, needle, tongs, sinker and separator) having portions contacting knitting yarn when a knitting operation is carried out with these parts installed in a knitting machine, a surface of a portion, which frequently contacts at least knitting yarn (11), of a metal substrate (10) of a part is coated with a composite plating layer (12) consisting of an electroless nickel alloy plating layer in which fine silicon particles, the surfaces of which are coated with a hard carbon film, are dispersed and contained. This method enables the durability of a knitting part to be improved to a level equal to that of the durability of a knitting part in which the surface of a substrate thereof is coated with a hard carbon film, and moreover, the part coating cost to be greatly reduced.
