针织物纳米TiO_2防紫外转移涂层

Transfer coating of knitted fabric with nano TiO_2

利用纳米TiO2的防紫外线性能,采用转移涂层技术将其涂覆于白色纯棉针织物上。试验表明,织物表面涂层含质量分数为0.8%的TiO2,就具有良好的防紫外线性能,且效果持久。经过测试,15次水洗,紫外线防护系数UPF仍大于50,UVA则小于5%,服用性能不受影响。

Nano TiO2 is coated on white cotton knits with transfer coating technique for UV resistance. The coatings with only 0.8% of TiO2 feature good and durable anti-UV property with UPF value more than 50 and UVA transmission less than 5% even after 15 laundering cycles, and little effect on wearability.
