摘要:
A fabric-softening composition comprises a dispersing agent, in particular a detergent-active compound, and a sultone of from 14 to 30 carbon atoms of the structure ##STR1## in which each of R.sub.1 and R.sub.2 is H or an aliphatic hydrocarbon radical having a chain of from 1 to 27 carbon atoms, at least one of R.sub.1 and R.sub.2 has a chain of at least 10 carbon atoms, and n is 1 or 2. Fabrics are softened by treatment with such a composition in the form of a dilute aqueous dispersion.
摘要:
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.
