项目摘要

To increase wettability of synthetic textile fibers and serviceability properties of the fabrics, the 172 nm ultraviolet (UV) excimer light exposure was carried out in ambient air. Model polymer surfaces, polyethylene, nylon and acetate, were prepared on the quartz crystal microbalance (QCM) and their detergency was investigated from the frequency change of the QCM due to cleaning. The removal of long-chain fatty acid in the aqueous detergent solutions was explained in terms of the free energy change resulting from the penetration of the detergent solution between the fatty acid film and the substrate in the zone of contact. The deposition of polymer particles onto the polymer surfaces in water/ethanol mixture was consistent with the total potential energy of interaction calculated on the basis of the extended DLVO theory. In addition, the changes in the hydrophilic properties and the detergency of the above polyethylene surface due to the UV irradiation were successfully evaluated by the QCM simulation. Moreover, the experimental results obtained using the commercially available polymer films indicated the validity of the UV treatment on the polymer surface.The 172 nm ultraviolet (UV) excimer light was exposed to textile fabrics of acetate, nylon 6, poly (ethylene terephthalate), acrylic and polypropylene. No significant changes in the tensile extension parameters and the surface reflectance of the fabrics due to the UV exposure were observed. X-ray photoelectron spectroscopy XPS) and the atomic force microscopy (AFM) showed that the UV irradiation to the PET fabrics increased oxygen concentration and roughness on the single fiber surfaces. As is expected, remarkable increase in wettability of the single fiber was accomplished and hence the capillary wetting and the moisture absorption of the fabrics were successfully enhanced by the UV treatment. In addition, detergency and dyeability were found to improve after the UV treatment.

为了提高合成纺织纤维的润湿性和织物的使用性能，在环境空气中进行了 172 nm 紫外线 (UV) 准分子光曝光。在石英晶体微天平（QCM）上制备模型聚合物表面（聚乙烯、尼龙和醋酸酯），并根据清洁时 QCM 的频率变化来研究它们的去污力。洗涤剂水溶液中长链脂肪酸的去除可以通过洗涤剂溶液渗透到接触区域的脂肪酸膜和基材之间所产生的自由能变化来解释。水/乙醇混合物中聚合物颗粒在聚合物表面上的沉积与基于扩展 DLVO 理论计算的相互作用总势能一致。此外，通过QCM模拟成功评估了上述聚乙烯表面因紫外线照射而产生的亲水性能和去污力的变化。此外，使用市售聚合物薄膜获得的实验结果表明了聚合物表面紫外线处理的有效性。将172 nm紫外（UV）准分子光照射到醋酸纤维、尼龙6、聚对苯二甲酸乙二醇酯、丙烯酸酯和聚丙烯的纺织织物上。没有观察到由于紫外线照射而导致织物的拉伸延伸参数和表面反射率发生显着变化。 X射线光电子能谱（XPS）和原子力显微镜（AFM）表明，紫外线照射PET织物增加了单纤维表面的氧浓度和粗糙度。正如预期的那样，单纤维的润湿性显着增加，因此通过紫外线处理成功地增强了织物的毛细管润湿和吸湿性。此外，经紫外线处理后，去污力和染色性也得到改善。
