    Abstract: PURPOSE:A polyester fiber, having a remarkable color developing property, and covered with longitudinal discontinuous hollows of specific depth and finer unevennesses on the surface thereof. CONSTITUTION:0.1-5wt% silicon oxide containing aluminum oxide having an average primary particle size of 100mmu or less is added to any stage of a polyester till the completion of polymerization, and the resultant spun and drawn fiber is heated in an alkaline aqueous solution, e.g. caustic soda, to hydrolyze the fiber surface. According to the method, a polyester fiber covered with 5-30discontinuous hollows of depth 0.3-0.8mu and long in the fiber axis direction per 100mu and finer unevennesses is obtained.

    Abstract: PURPOSE:To obtain a soft textile material having durable moisture-absorptivity and antistaticity and free from stuffy feeling by compounding a specific acid component with a specific monomer, etc., at specific weight ratios, applying the obtained emulsion liquid to a textile material and polymerizing on the surface of the fiber. CONSTITUTION:A vinylcarboxylic acid and/or a vinylsulfonic acid [preferable examples: (meth)acrylic acid and 2-acrylamido-2-methylpropanesulfonic acid] and a divinyl monomer of the formula (X is H or CH3; (n) is 1-4) are compounded at a weight ratio of (l-20):1 and a polymerization initiator (preferable example: ammonium persulfate) is emulsified with an emulsifier such as nonionic or anionic surfactant. The obtained emulsion liquid is applied to yarns, woven fabrics, knit fabrics, etc., composed of a synthetic fiber, a natural animal or vegetable fiber, etc., and polymerized on the fiber surface by treating with steam under normal pressure to form a uniform resin coating film on the fiber surface. The obtained fiber has soft texture, excellent durability to washing and rubbing and high moisture-absorptivity and hydrophilic nature and, accordingly, it has high antistaticity, soil-releasing property and color fastness.
