A polyester-based spandex filament or film is provided. The filaments when used in swim-wear fabrics provide the fabrics with increased resistance to mildew-induced degradation. The filaments are formed from a spandex derived substantially from a poly(2,2-dimethyl-1,3-propylene 1,12-dodecanedioate)glycol having no more than 15 milliequivalents of glycol acidity per kilogram of glycol, which glycol is capped with an organic diisocyanate and then chain-extended with an aliphatic diamine.
提供了一种聚酯基氨纶长丝或薄膜。 这种长丝用于泳装面料时,可提高面料的防霉降解性能。 这种长丝是由聚(2,2-二甲基-1,3-丙烯-1,12-十二烷二酸)乙二醇制成的氨纶,这种乙二醇的酸度不超过每千克乙二醇 15 毫当量,乙二醇用有机二异氰酸酯封端,然后用脂肪族二胺扩链。
