Abstract
A multi-filament yarn is subjected to soft twist of 4 to 9 twistings in every 10 cm in a single direction thereby forming a warp yarn. Weft yarns are passed, at a density of 1 to 3 yarns in every 5 cm, crosswise over and under a plurality of the warp yarns parallel-arranged in a set width, thereby forming a cord fabric. The cord fabric is subjected to adhesion treatment with an adhesive so that an adhesive content per unit area thereof reaches 2 to 5%, is subjected to heat treatment so that the warp yarns reaches 1 to 4% in heat shrinkage percentage and is then cut at set lengths thereby obtaining short fibers.
