自体涂层双重防护服用织物的开发

为使织物同时获得较好的防紫外线和防电磁辐射的功能，且保持功能的持久性，设计了由织物基层、防护层和纳米二氧化钛涂层3 部分组成的防护织物。防护层采用超细镀银涤纶丝作为原料，按照加强斜纹组织结构设计，与织物基层以双层组织原理按照自体接结的方式进行连接，在防护层外侧用纳米二氧化钛防紫外线涂料进行涂层整理，并测试织物的紫外线防护性能和防电磁辐射性能。根据正交试验结果，利用灰色聚类分析确定最优工艺参数。结果表明：防护织物的紫外线防护系数为60.1，平均屏蔽效能为99.992 0%；最大屏蔽效能为99.998 9%，所对应频率为120 MHz；最小屏蔽效能为99.958 6%，所对应频率为205 MHz。

Development of self-coated dual protective fabric

A functional protective clothing fabric composed of a fabric layer, a protective layer and a nano-TiO2 coating layer with good anti-ultraviolet and anti-electromagnetic radiation properties was developed. Specifically, the superfine silver plating polyester filament was used to fabricate the protective layer according to the reinforced twill weave. The peotective layer was conneced with the fabric layer according to the specially designed double layer weave. Nano-TiO2 was coated on the surface of the protective layer to form the anti-ultraviolet coating layer. The ultraviolet protection and anti-electromagnetic radiation performance of the fabric were tested, respectively. According to the principle of orthogonal test, grey cluster analysis was adopted to determine the optimal processing parameters. The results show that the ultraviolet protection coefficient, the average shielding effectiveness, the maximum shielding effectiveness and the corresponding frequency, the minimum shielding effectiveness and the corresponding frequency of the designed functional protective clothing fabric are 60.1, 99.992 0%, 99.998 9% and 120 MHz, 99.958 6% and 205 MHz, respectively.
