Abstract
Abstract A composite yarn construction particularly adapted for use in cut resistant body protective apparel and comprising a core yarn and an abrasion and cut resistant monofilament covering yarn knitted onto and encasing the core yarn in a series of cut resistant loops. The core yarn is preferably a multifilament synthetic yarn such as nylon, and the knitted yarn is stainless steel. The yarn is suitable for knitting cut resistant gloves, and apparel.
