In order to provide a fabric and a fiber product, which have hygroscopicity and durability as well as flame retardancy, a hydrophilizing agent is added to a fabric containing aramid fibers.

A blocked polyisocyanate-containing curable silicone composition includes an amino group-containing organopolysiloxane, a blocked polyisocyanate and a catalyst which is an organic base compound and/or a metal compound. The composition has a high curability even under low-temperature conditions and, when used as a textile treatment, imparts textile fibers and products with good softness and water absorbency, and also has an excellent durability to washing.

A polyamide monofilament is characterized in that the abrasion tension thereof when passed through a ceramic guide is 0.3 cN/dtex or less and in that the amount of static electricity generated at the exit of a chromium round bar guide, which is a frictional body, when the polyamide monofilament is passed through the chromium round bar guide, is 300 V or less. This polyamide monofilament and fiber package provide a gauze woven fabric for which tension is low when passing through a thread path guide when warping warp yarn, for which generation of static electricity is suppressed, and which has excellent weaving productivity.

Present invention is related to a hydrophilic silicone polymer prepared by using an olefinic unsaturated polyoxyalkylene epoxy compound. An amine compound having at least one tertiary amine group which may be further reacted with the polyoxyalkylene epoxy siloxane molecule is used further for preparing such hydrophilic ABA molecule for improving both the feel and hydrophilicity in any natural or artificial fiber, thus solving the most challenging problem of balancing i.e. improving both hydrophilicity and feel property in the field of fabric or fiber treatment. The present invention also relates to the process of preparation of the said hydrophilic silicone polymer and its emulsion.
