Beschreibung
Zusammenfassung:	PROBLEM TO BE SOLVED: To provide polyurethane-urea fibers with stability to chlorine water, for example preventing deterioration of physical properties in contact with chlorine water in swimming pool. SOLUTION: The chlorine-resistant elastic polyurethane urea fibers are obtained by adding 0.05-10 wt.% of fine particles of hydrotalcites coated with 0.2-15 wt.% of metal fatty acid salts to the the polyurethane urea in spinning solution, setting the fine particles of hydrotalcites to locate in and/or surface of the fiber. The stabilizer prevents harmful effect of itself on the spinning process and deterioration of physical properties of the polyurethane urea fibers. COPYRIGHT: (C)2004,JPO&NCIPI
