Testing on spunbond performance of anti-ultraviolet
摘要
Abstract
Spunbond nonwovens of shading material UV radiation performance is studied. The ultraviolet transmittance influence of polypropylene spunbond by different sample surface density was test and analysed. The samples ultraviolet transmittance change after exposure of deuterium lamp which imitated the sun ultraviolet was studied. The change of samples strength after exposure of the deuterium lamp was test. The ultraviolet transmittance of polypropylene spunbond nonwovens after the change nonwovens layers was test. The results showed that with polypropylene spunbond nonwovens surface density increases , UVA and UVB transmittance change trend to exponential decline. With the time which deuterium lamp imitation of sun exposure increases, the ultraviolet resistant effect would be gradually become poor and the breaking strength would decreases. The ultraviolet transmittance of samples trends to exponential decline with nonwovens' layers. And with layers increase UVB transmittance is down quickly, UVA transmittance is down slowly.关键词
