Elastic composite yarns from brittle ceramic yarns.

摘要

The present invention includes a composite yarn, a temperature resistant article stitchbonded with brittle yarn, and an article knitted of brittle yarn. The composite yarn is comprised of a brittle yarn 14 or 24, a flexible, load-bearing yarn 12 or 22, and a flexible wrap yarn 16 or 26 which secures said core yarn and said brittle yarn together. The wrap yarn may be helically wrapped around the load-bearing core yarn and the brittle yarn, or the wrap yarn may secure the load-bearing core yarn and the brittle yarn together with a series of connected loops forming a knitted pillar of chain stitches. The present invention makes possible fabrics stitchbonded with or knitted from brittle yarns made on commercial stitchbonding and knitting machines.
