中文摘要：对含有间苯二甲酸-5-磺酸基团(SIP)的异形聚酯纤维碱水解性能进行了研究。结果表明,在恒温及碱浓度较低时,纤维减量率与时间呈较好的线性关系,减量程度随共混HCDP中磺酸基团摩尔分数的增加而增加。纤维的减量率除受处理温度、碱浓度以及时间等因素的影响外,较大程度上还受到纤维横截面形状的影响。由于HCDP与PET碱水解效率的差异,共混纤维上会形成较多尺寸不等的微狭隙结构。说明纤维经过适当的氢氧化钠处理后具有较好的水分传输性能。

外文摘要：Alkaline hydrolysis properties of modified polyester fiber containing soldium-5-sulfo-iso-phthalate （SIP） is studied. Experiments indicate that weight loss of the fiber has good linear relationship with treatment time at constant temperature and lower NaOH concentration, and the degree of fiber weight loss increases with the increase of SIP in the HCDP fiber. Besides treatment temperature, alkaline concentration, and treatment time, weight loss of the fibers is affected by profiled cross-section of fibers considerably. Owing to the different hydrolytic degree between HCDP and PET, after treatment, more microcellular structures on the surface of HCDP, indicating that the fiber has better water transportation ability.
