摘要/Abstract

摘要： 涤纶织物表面疏水，服用舒适性差。同时也限制了其在生物医学、生物组织上的应用。本文研究了涤纶表面的离子化亲水改性。研究结果表明：经离子化改性后，涤纶织物的水接触角从157.25o减少到0°，毛细上升高度从0.35cm上升到14.93cm；亲水性不因存放时间和洗涤次数而降低。扫描电镜（SEM）观察表明纤维在改性后表面凹槽略有增加；红外光谱分析表明改性纤维表面有磺酸基；X-射线衍射表明改性涤纶的晶体结构未发生明显变化。同时，改性涤纶织物的强力、折皱弹性、硬挺度在可应用范围内保持良好。

Abstract: Abstract Polyester is used widely because of its outstanding wearability. But simultaneously, the application of polyester fabric is confine due to its limited hygroscopicity. In this paper, the polyester fabric was ionized with ionization reagent. The results showed that the ionized polyester fabrics had wonderful hydrophilic property. The water contact angle decreased from 157.25o to 0°; the capillary rise height increased from 0.35cm to 14.93cm; and the hydrophilicity of modified polyester fabric did not decrease in the storage and washing process. SEM showed there were more grooves on the surface of the fibers.And there was sulfo group on the fabric according to infrared spectroscopic analysis. Besides, X-ray showed the crystal texture changed little. And the strength, elasticity and rigidity of ionized polyester were kept well. The result showed ionized method on polyester fabric was potential applied technology.

Key words: polyester fabric, ionization, hydrophilicity, sulfo group
