Tough tough gauze is a kind of interwoven fabric -- traditionally, it is pure silk tough gauze. Base tough tough gauze is a heavily-raised silk fabric, made from nylon silk and glossy viscose silk. This is a mixed mixed silk fabric. Because nylon silk and viscose silk have different acid-proof properties, the flowers and the ground are clearly distinct after being burnt. The fabric has the characteristics of transparent ground, bright pattern and light and crisp texture.
