Abstract
A combined yarn is provided containing a metallic strand and a non-metallic strand, wherein the metallic and non-metallic strands are combined by air interlacing the filaments or fibers of the non-metallic strand at intermittent points along their length, so that the metallic strand is encased in the non-metallic strand at least at some of the intermittent points; a composite yarn incorporating the combined yarn as at least one component, and articles and/or garments made from the combined yarn or composite yarn, and methods for the production of the combined and composite yarns.
Claims31
A combined yarn comprising:
- i) at least one metallic strand;
- and
- ii) a single non-metallic strand;
- wherein said single non-metallic strand is a multifilament strand or spun strand and wherein filaments or fibers of the single non-metallic strand are air interlaced with each other at intermittent areas along the lengths of said filaments or fibers, and said metallic strand being encased within said single non-metallic strand along at least a part of the length of said metallic strand.
A composite yarn comprising:
- a) a core comprising:
- i) at least one metallic strand;
- and
- ii) a single non-metallic strand;
- wherein said single non-metallic strand is a multifilament strand or spun strand and wherein filaments or fibers of the single non-metallic strand are air interlaced with each other at intermittent areas along the lengths of said filaments or fibers, and said metallic strand being encased within said single non-metallic strand along at least a part of the length of said metallic strand;
- and
- b) a first cover strand wrapped around said core.
A method of manufacturing a yarn comprising:
- a) positioning a at least one metallic strand adjacent a single non-metallic strand, wherein said non-metallic strand is a multifilament or spun yarn;
- and
- b) passing said at least one metallic strand and said single non-metallic strand through an air jet texturizing device where an air jet impinges against said strands at intermittent points to entangle filaments or fibers of said single non-metallic strand, thus encasing said at least one metallic strand at least at some of said intermittent points.
