Study on Anti-ultraviolet Property of the Anti-ultraviolet Polyester Fabrics

To study the influence of the content of the anti-ultraviolet polyester yarns on the anti-ultraviolet performance of the polyester fabrics,two sets of samples used anti-ultraviolet polyester yarns and common polyester yarns were woven for the experiment.Integrating sphere method was used to test the anti-ultraviolet performance of the samples and their UPF and T(UVA)AV were calculated,which were taken as index of ultraviolet protection effect.The results indicated that: the anti-ultraviolet performance of the polyester fabrics enhanced as the content of the anti-ultraviolet polyester yarns increased after embedding the anti-ultraviolet polyester yarns in polyester fabrics,the results fitted with polynomial Y=A+B1X+B2X2+B3X3 had significant correlation;for the single-layer polyester fabrics and the double-weft polyester fabrics,when the content of the anti-ultraviolet polyester yarns was higher than 26.7 % and 23.1 %,the value of the UPF was higher than 40 and the value of the T(UVA)AV was lower than 5 %,the anti-ultraviolet performance of the two fabrics was better.
