Effect of weaving structure parameters of fabric on ultraviolet transmittance

Theoretical analysis of weaving structure parameters affecting ultraviolet transmittance is analyzed.Fabrics with different weaves and different structure parameters are prepared.The ultraviolet transmittance of the fabrics is tested to verify the reasonableness.The results show that ultraviolet transmittance is increased when average floating points increased,and it is affected by intertexture.Pores of fabrics are main factors to affect ultraviolet transmittance,it not only has relation to covering factors,but also concerns average floating points,intertexture and variability of interweave.
