摘要： A synthetic fiber which is excellent in moisture-absorbing/releasing property and exhibits high elongation and high stretch recovery, characterized in that it has moisture absorption ratios of 0.5 to 4.0% by weight in environments of 20° C.×65% RH and that of 4.5% by weight or more in environments of 30° C.×90% RH, respectively, and also has a difference between the absorption ratios in both the environments of 4.0% by weight or more. The representative examples of such fibers include polyurethane synthetic fiber and polyether synthetic fiber. The synthetic fiber maintains a high strength at break of an elastic fiber component thereof also in the state of having absorbed moisture, is excellent in color fastness to rubbing, and can be used for manufacturing a stretch fiber fabric product excellent in comfort through blending with another fiber material. The synthetic fiber can be produced by incorporating a water absorption resin having a water absorption ratio in a range from 500 to 4000% by weight into an elastic fiber such as a polyurethane fiber or a polyurethane-urea fiber in a finely dispersed state in an amount in a range from 1 to 15% by weight relative to a fiber-forming polymer.
摘要翻译：一种吸水/脱模性优异，伸长率高，拉伸恢复性高的合成纤维，其特征在于，在20℃×65％RH的环境下，其吸湿率为0.5〜4.0重量％在30℃×90％RH的环境下分别为4.5重量％以上，并且在两个环境中的吸收比都为4.0重量％以上。这种纤维的代表性实例包括聚氨酯合成纤维和聚醚合成纤维。合成纤维在其吸收水分的状态下也保持其弹性纤维成分的高强度断裂，耐摩擦色牢度优异，可用于制造舒适性优异的拉伸纤维织物产品纤维材料。合成纤维可以通过将吸水率为500〜4000重量％的吸水性树脂以微细分散状态的聚氨酯纤维或聚氨酯 - 尿素纤维等弹性纤维的量加入，相对于成纤聚合物为1〜15重量％。
