摘要

针对氢氧化钠可破坏聚酯纤维结构,影响异形截面聚酯纤维的芯吸效应、润湿性、强力、伸长性能和吸湿快干及吸湿凉爽功能这个问题,借助扫描电子显微镜,对氢氧化钠处理前后的纤维形态结构进行了表征,分析了影响该纱线芯吸效应的因素,研究了不同质量分数碱处理对异形截面聚酯纱线芯吸效应、润湿性能、强力及伸长的影响规律。结果表明:异形截面聚酯纤维横截面为十字形,沿纤维纵向有4道沟槽,起到毛细管作用,为水分的迁移提供了通道,使纤维及纱线具有良好的芯吸效应;氢氧化钠可有效清除异形截面聚酯纤维沟槽中的低聚物,当氢氧化钠质量分数在4%左右时,纱线芯吸效果显著提高;氢氧化钠处理可提高异形截面聚酯纱线的润湿性;随着氢氧化钠质量分数的提高,异形截面聚酯纱线强力及伸长下降,当氢氧化钠质量分数高于6%后,纱线的强力和伸长损失显著。
        Aiming at the problem that Na OH could damage the structure of polyester fiber and affect the wicking effect,wettability,strength and elongation properties of profiled polyester fiber,and fast drying and cool properties,scanning electro microscopy was adopted to characterize the structure of the fiber before and after NaOH treatment. The influencing factors of wicking effect was analyzed and the influences of alkali concentration on wicking effect,wettability,strength and elongation properties were studied. The results show that the cross section of profiled polyester fiber is cross shaped. Four trenches along the longitudinal direction of the fiber play the capillary role and provide a channel for the migration of moisture. Therefore,the profiled polyester fiber and yarn have good wicking effect. Sodium hydroxide can effectively remove the oligomers from profiled polyester fibers,and the wicking effect of profiled polyester yarns is improved significantly when the concentration of alkali is about 4%. It is found that profiled polyester yarns treated by NaOH solution have good wettability. With the increase of the alkali concentration,the strength and elongation of profiled polyester yarns decrease,and the strength and elongation properties of the profiled polyester yarns are lost significantly while the alkali agent concentration is higher than 6%.
