Abstract: A fiber or fabric having durable hydrophilicity and excellent anti-staticity is produced by adhering specific amount of a fiber treating agent comprising the following components (A), (B), (C), (D) and (E) each at the following ratio onto the surface of thermoplastic resin fiber or fabric (A). 20 to 40% by weight polyglycerin fatty acid ester of specific structure, based on the total of (A) to (E); (B). 5 to 20% by weight of polyoxyalkylene modified silicone of specific structure, based on the total of (A) to (E); (C). 10 to 25% by weight of alkyl imidazolium alkyl sulfate of specific structure, based on the total of (A) to (E); (D). 5 to 20% by weight of alkylene oxide adduct of alkanoylamide, based on the total of (A) to (E); (E). 25 to 40% by weight of polyetherester of specific structure, based on the total (A) to (E).

Abstract: A polyethylene fiber having a high apparent Young's modulus, high breaking tensile strength and low breaking elongation. The fiber also exhibits residual percentage crimp suitable enough for carding, so that the cardability, which has been conventionally difficult to improve, can be remarkably increased. Further, the fiber can be formed into a non-woven fabric having a soft touch feeling such that the fabric is suitable for medical use as well as hygienic use. In addition, the polyethylene fiber of this invention can be mixed with other fibers such as cellulose fiber to obtain a high absorbent fiber network material.

Abstract: The invention is directed to a crimpable composite fiber having a propylene copolymer is the first component and a polyethylene as the second component.
