Abstract

Polyester (PET) fabric is an important fabric to make sportswear due to its good mechanical strength, wear resistance and low cost, but poor hygroscopicity will accumulate moisture and excessive heat of human body which thereby causing thermo-physiological dicomfort. To obtain satisfying moisture-wicking, hydroscopic and fast-dry properties, facile and efficient single-sided click chemistry was used to substitute traditional methods. Firstly, PET fabric was alkali treated and modified with 3-mercaptopropyltrimethoxysilane to obtain thiol groups. Then it was gradiently grafted with potassium 3-sulfopropyl acrylate by thiol-ene click chemistry under single-sided ultraviolet (UV) irradiation to enlarge effects. The reaction was proved by FTIR and Ellman method, the surface morphology was observed by SEM, and the mass loss at different temperatures in thermalgravimetry (TG) test illustrated the quantity change of grafting. The results demonstrated that the resultant fabric has good performance of moisture absorbing and sweat releasing, fast drying as well as outstanding antistatic and soil release properties.

紫外线诱发的点击反应制备的耐用吸湿排汗速干涤纶织物

摘要

聚酯（PET）织物由于其良好的机械强度，耐磨性和低成本而成为制造运动服的重要织物，但吸湿性差会积聚水分和人体过多的热量，从而引起热生理不适。为了获得令人满意的吸湿排汗，吸湿和快干性能，使用了简便高效的单面点击化学替代了传统方法。首先，对PET织物进行碱处理并用3-巯基丙基三甲氧基硅烷改性以获得硫醇基。然后在单侧紫外线（UV）照射下，通过硫醇-烯点击化学将丙烯酸3-磺基丙酯钾梯度接枝。通过FTIR和Ellman方法证明反应，通过SEM观察表面形态，热重（TG）试验在不同温度下的质量损失说明了接枝量的变化。结果表明，所得织物具有良好的吸湿排汗性能，快速干燥以及优异的抗静电和去污性能。
