ABSTRACT:
A knitting machine part which is resistant to abrasion caused by knitting a yarn of cut-resistant fiber contains: (i) a base substrate having at least one yarn-contacting region for contacting the yarn during the knitting process, and (ii) a coating disposed on the surface of the base substrate on at least the yarn-contacting region of the base substrate, wherein the coating contains titanium carbonitride having a carbon-to-nitrogen weight ratio of from about 1:4 to 4:1, preferably from about 1:1.5 to 1.5:1, most preferably about 1:1. The knitting machine part is preferably a knitting needle or a sinker. The cut-resistant yarn is preferably composed of at least one cut-resistant fiber formed from a fiber-forming polymer and a hard filler having a Mohs Hardness value of at least about 3, the hard filler being distributed in the fiber-forming polymer. The coated knitting machine part may also be used to knit conventional fibers and yarns, for example, fibers and yarns which are not cut-resistant, including abrasive fibers which are not cut-resistant.
