Abstract

Generally blended fabrics can satisfy the specific needs of a clothing material in terms of comfort and aesthetic value; however some blends lack uniform functional properties due to differences in their chemical properties. A study was carried to apply an ultraviolet protection finish by titanium oxide nanoparticles based emulsion on 50/50 silk/lyocell intimate blended fabric. The functional finishing process has been optimised by a design of experiment using Box and Behnken model with three variables such as concentration of TiO₂ nanoparticles, padding time and curing temperature at three levels. The ultraviolet protection factor, tensile strength, air permeability, bending length, water absorbency and surface morphology of finished fabrics were evaluated; followed by regression analysis for optimisation in statistical software Design Expert 8.1. The optimum condition for UV protection finishing on silk/lyocell blended fabric was 5.85% TiO₂, 35 min padding time and 98 °C curing temperature and the respective finished fabric sustained its desirable functionality up to 15 washing cycles.

摘要

一般来说，混纺面料可以满足服装面料在舒适性和审美价值方面的特定需求；然而，由于化学性质的差异，一些共混物缺乏统一的功能特性。一项研究通过基于氧化钛纳米粒子的乳液在 50/50 真丝/莱赛尔紧密混纺织物上应用紫外线防护整理剂。通过使用 Box 和 Behnken 模型以及 TiO ₂浓度等三个变量的实验设计优化了功能性整理过程纳米粒子、填充时间和固化温度三个级别。对成品织物的紫外线防护系数、拉伸强度、透气性、弯曲长度、吸水率和表面形貌进行评价；然后在统计软件 Design Expert 8.1 中进行回归分析以进行优化。在丝绸/莱赛尔混纺织物上进行紫外线防护整理的最佳条件是 5.85% TiO ₂、35 分钟轧染时间和 98 °C 固化温度，并且相应的整理织物在长达 15 次洗涤循环后仍能保持其理想的功能。
