求翻译：成衣烂花最主要的原理是烂掉了衣服中的一部分棉，剩下的就是涤和少量的棉，所以我们在设计面料时就得设定好棉和涤的成份，这样就能出来我们想要的效果。是什么意思？

Clothing burnt-out main principle is part of the rot in the clothes of cotton, the rest is polyester and a small amount of cotton, so we designed the fabric will have to set a good element of cotton and polyester, so get out the effect we want.
