Fiber having durable hydrophilicity and fabrics using the same

The present invention provides a durable hydrophilic fiber and fabric using said fiber having superior durable hydrophilicity being able to utilize preferably in the medical or hygienic material sections. The durable hydrophilic fiber of the invention can be obtained by applying 0.2 to 1.5% by weight of a fiber treating agent to a thermoplastic fiber based on the thermoplastic fiber. The fiber treating agent contains at least 40% by weight of a mixture comprising 80 to 20% by weight of (A) betaine ampho-ionic surface active agent and 20 to 80% by weight of (B) di-carboxylic acid ester compound from polyalkylene adduct of hydroxy-fatty acid ester.

Durable hydrophilic fiber and fabric using the same

Modified polyolefin fibers capable of easily producing a non-woven fabric having a high strength and a superior feeling, and provided with a broad range of processing temperature and further a low temperature adhesiveness and suitable to heating roll processing, and a non-woven fabric using the same are provided,

Modified polyolefin fibers and a non-woven fabric using the same

A water-repellent fiber having adhered to the fiber surface of a thermoplastic resin, which is a fiber a textile oil in the amount of 0.1-0.8% by weight of the fiber comprising ingredients of the following (A), (B) and (C) wherein the textile oil comprises: (A) 5-15% by weight of at least one alkylsulfonate, (B) 5-45% by weight of at least one compound selected from polyol esters and aliphatic acid alkanol amides, and (C) 40-90% by weight of at least one compound selected from dibasic acid esters and polyethylene glycol esters.

Water-repellent fiber and nonwovens made of the fiber
