Another possibility to check approximately the feather and down proofness is to measure the airpermeabilityof the fabric.
另外可能近似测试出羽毛羽绒不穿透性的方法是:测量面料的空气渗透性。

Color silk fabric is of good airpermeability and wet absorption as well as good ultraviolet ray absorption and anti-bacterial property but poor anti-crease, weak strength and easy yellowed.
After enzyme treatment, the fabric became more fluffy, the amount offabric hairiness reduced. Drape coefficient, airpermeability, whiteness and capillary effect were improved to some extent.
