蜂窝状微孔结构改性聚酯纤维的吸放湿性能研究

对蜂窝状微孔结构改性聚酯纤维的吸湿和放湿性能进行了研究。通过测试该新型纤维和普通聚酯纤维在标准大气条件下的吸湿、放湿回潮率,绘制出吸湿、放湿曲线,并得到2种纤维达到吸湿、放湿平衡的过程中回潮率对时间的回归方程。结果显示,蜂窝状微孔结构改性聚酯纤维的回潮率和初始吸湿和放湿速率远高于普通聚酯纤维的相应性能,具有优良的吸湿排汗性能。

Moisture absorption and liberation properties of honeycomb micropore modified polyester fiber

The moisture absorption and liberation properties of honeycomb micropore modified polyester fiber were studied. Through testing moisture absorption, liberation regains of honeycomb micropore modified polyester fiber, and normal polyester fiber in standard atmospheric conditions, their moisture absorption and liberation curves were depicted. The regression equa- tions of moisture regains to time during their reaching, the balance of moisture absorption and moisture liberation were obtained according to the curves. Their moisture absorption and liberation rate curves were analyzed, and the regression equations of the rates to time were obtained. The results show that the moisture regain, initial moisture absorption rate, and moisture liberation rate of honeycomb mieropore modified polyester fiber is much higher than those of normal polyester fiber with excellent performance of the moisture absorbance and sweat transportation properties of honeycomb micropore modified polyester fiber.
