户外多功能织物的制备与性能

Preparation of outdoor multifunctional fabric and its properties

以制备的纳米二氧化钛水溶胶与γ-缩水甘油氧丙基三甲氧基硅烷复合水溶胶对棉织物进行功能整理,设计具有防紫外线、防水及良好服用性能的户外多功能织物。测试结果表明:整理后棉织物的防水性能与防紫外线性能随着复合水溶胶中纳米二氧化钛浓度的增大而增大;断裂强力呈现先上升后下降的趋势;折皱回复角、白度、回潮率均出现不同程度的下降。当复合水溶胶中的纳米二氧化钛浓度为0.3 mol/L时,整理后的棉织物经过皂洗与摩擦后,依然保持良好的防紫外线、防水与服用性能。

The cotton fabric is treated with nano-titanium dioxide hydrosol andγ-glycidyl oxypropyl trimethoxysilane composite hydrosol to design the outdoor multifunctional fabrics with ultraviolet protection,waterproof and good wearability.The test results show that the waterproof and UV resistance of the finished cotton fabrics both increase,the breaking strength increases first and then decreases,and the crease recovery angle,whiteness,moisture regain and smoothness all decrease to different degrees with the concentration of nanometer titanium dioxide in the composite hydrosol rising.When the nano-titanium dioxide in the composite hydrosol reaches 0.3 mol/L,the finished cotton fabric still can maintain good UV protection,waterproof and wearable properties after soaping and rubbing.
