Abstract

A warp-knit support tape for hook and loop fasteners comprises a foundation including two needle stitches and laid-in weft threads, and a pile portion having chain stitches formed by sinker looping into a multiplicity of pile-loops. The tape system is rendered highly resistant to stretch in either direction. The pile-loops are arranged to line up alternately at the right and at the left of the wales and tilted sidewise alternately in opposite directions.
