Woven fabrics and a method of forming the same |
(57) A method of forming a woven fabric comprises interweaving polyester warp yarns with
a plurality of weft yarns, at least some of the weft yarns being polyamide multifilament
yarns impregnated with a non-cross-linked homolpolymer or copolymer of acrylic acid.
After weaving the fabric is subjected to heat treatment to cause the impregnated agent
to cross-link and chemically bond to the polyamide yarns, but not to the warp yarns.
The resulting laterally stiffened fabric is particularly suitable as webbing for use
in vehicle safely harnesses.
