ABSTRACT:
The present invention makes possible fabrics stitchbonded with or knitted from brittle yarns by providing a composite yarn which is able to be used in commercial stitchbonding and knitting machines, the new composite yarn comprising a load-bearing core yarn, a brittle yarn and a wrap yarn which secures the core yarn and the 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.
