ABSTRACT:
A process for the preparation of a woven fabric of low air permeability which comprises preparing a woven fabric by use of a composite fiber of a splitting and severing type, which consists of polyester and polyamide and produces extremely fine fibers of 0.001 to 0.8 denier size, as a warp and/or a weft; treating thus obtained woven fabric by use of an aqueous emulsion of a swelling agent for polyester and nylon under the conditions where nylon is mainly allowed to swell and then shrink; scouring and dyeing the woven fabric; and after calendering the woven fabric with the use of heated rollers rotated under pressure.
