Abstract: Cotton woven fabric was treated on three condition, placing in laboratory, irradiating with 8 UVB-313 UV lamp and soaking under 1.25m for different time, and the performance of tensile breaking strength and wrinkle resistance were tested. The results shows that, the tensile breaking strength and wrinkle resistance of cotton woven fabrics which was placed in the laboratory for some time steady slowly decline; ultraviolet radiation has a greatly influence on the wrinkle resistance performance, water has a greater impact on the tensile strength. The microorganisms in water have a acceleration effect on the fabric ageing. The lifetime prediction equation are proposed for outdoor air and warehouse storage of cotton woven fabric.

Key words: woven pure cotton fabric, lifetime prediction, warehouse storage, ultraviolet radiation, soaking in water
