摘　　要：选取39块不同类型的棉型织物,在波长365 nm与254 nm紫外线下进行紫外线透过率性能测试,以及织物平方米重量、透气率与厚度测试,分析了波长254 nm与365 nm紫外线对棉型织物的透过性规律以及织物平方米重量、透气率、厚度与紫外线透过率的关系。结果表明:同等工艺条件下波长365 nm紫外线透过性高于波长254 nm紫外线;2种波长紫外线透过性成正相关;影响织物紫外线透过率最大因素是平方米重量,织物透气性、织物厚度也是重要影响因素。研究成果对棉型织物防紫外线整理起到参考作用,对纺织产品防紫外线性能改善有借鉴意义。Thirty-nine different cotton fabrics were tested for their ultraviolet transmittance at the wavelength of 365 nm and 254 nm, and the square meter weight, air permeability and thickness of cotton were tested. The transmittance of ultraviolet radiation at the wavelength of 254 nm and 365 nm to cotton fabrics and the relationship between the square meter weight, permeability and thickness of fabric and ultraviolet transmittance were analyzed. The results showed that the ultraviolet transmittance at 365 nm was stronger than that at 254 nm under the same process conditions. The two kinds of ultraviolet transmittance were positively correlated. The greatest factor affecting the ultraviolet transmittance of fabrics was the square meter weight, and the permeability and thickness of fabrics were also important factors. The research results would play an auxiliary role in anti-ultraviolet finishing of cotton fabrics and play a reference role in improving the anti-ultraviolet properties of textile products.
