高支高密平纹面料紧度同透气性、防透视性的关系

The Relationship Between the Tightness and Air Permeability,Visual Shielding Property of High-count&High-density Plain Fabrics

用相同的纱线,调整不同密度的平纹组织工艺进行织布,同时后整理加工,得到不同密度的高支高密平纹面料。通过检测该类面料的经密、纬密,计算紧度,测试其透气性和遮盖率,可以很明显地看出透气性与面料紧度存在较强的负相关性,遮盖率同面料紧度存在较强的正相关性。紧度对透气性的影响相对防透视性的影响更大,调整面料的经纬密,需多考虑对面料透气性的影响。

Weave the plain fabrics in different densities with same yarn and obtain high-count and highdensity plain fabrics with different densities after finishing processing.By testing the warp density,weft density,tightness,air permeability and shielding rate,results indicated that there was a strong negative correlation between the air permeability and tightness,and a strong positive correlation between the shielding rate and tightness.And the effect of tightness on air permeability is greater than that of visual shielding property.Therefore,more consideration should be given to the effect on the air permeability of the fabric when adjusting the warp and weft density.
