摘要： An elastic polyurethane fiber comprising, based on the fiber weight, from 0.5 to 10% by weight of composite oxide particles containing aluminium and at least one combination of zinc and magnesium selected from the group consisting of combinations of zinc and magnesium in respective specific ratios. The elastic polyurethane fiber has excellent chlorine resistance, and is suitable for swimwear for use in swimming pools. The elastic fiber can be obtained by spinning a polyurethane spinning dope containing, based on the polyurethane, from 0.5 to 10% by weight of the composite oxide particles. Filter clogging and yarn breakage caused by secondary agglomeration of the composite oxide particles are extremely decreased, and stabilized spinning can be conducted over a long period of time.

摘要： An elastic polyurethane fiber excellent in chlorine resistance, which contains particles of a metal compound selected from oxides and hydroxides of a metal selected from zinc and magnesium, and composite oxides of zinc and magnesium, a treating agent selected from a fatty acid, a styrene/maleic anhydride copolymer or its esterified products and a phosphoric ester adhering to the surface of the particles. The elastic polyurethane fiber is appropriate for an elastic fiber material for swimwear used in a swimming pool. The elastic polyurethane fiber can be produced by spinning a polyurethane spinning dope containing the metal compound particles to which such a specific treating agent as mentioned above adheres. The spinning dope suppresses secondary agglomeration of the metal compound particles and enables stabilized spinning of a modified polyurethane fiber.
摘要翻译：一种耐氯性优异的弹性聚氨酯纤维，其含有选自锌和镁的金属的氧化物和氢氧化物以及锌和镁的复合氧化物的金属化合物的颗粒，选自脂肪酸，苯乙烯/ 马来酸酐共聚物或其酯化产物和粘附到颗粒表面的磷酸酯。弹性聚氨酯纤维适用于游泳池中使用的游泳用弹性纤维材料。弹性聚氨酯纤维可以通过纺丝含有如上所述的这种特定处理剂的金属化合物颗粒的聚氨酯纺丝原液纺丝来制备。纺丝原液抑制了金属化合物颗粒的二次凝聚，使得改性聚氨酯纤维的纺丝变得稳定。
