Multi-component yarn and method of making the same

摘要

A cut-resistant combined yarn (10) is described that includes a wire component. Kinking and knotting of the wire component resulting from stretching of the wire component during knitting is avoided by encasing the wire component within a cut resistant combined yarn that has a higher stretch resistance than the wire component. The combined yarn (10) includes a wire component comprising at least one strand (12) of stainless steel, a first non-metallic strand (14) of an inherently cut-resistant material, and a second non-metallic strand (16) of a cut resistant material, a non-cut resistant material or fiberglass. The non-metallic strands (14, 16) are air interlaced with each other to form intermittent attachment areas (13) along the lengths of the strands. At least one or the other of the strands is a multi-filament strand. During air interlacing operation, the two non-metallic strands (14, 16) encase the stainless steel strand (12) in the non-metallic strands at least in some of the zones. A composite yarn may be formed by wrapping at least one cover strand (36) about the combined yarn in a first direction. A second cover strand (38) may be wrapped about the combined yarn in a second direction opposite the first direction.
