Process points: When the ratio of mixed color to polyester is high, a secondary mixing method can be adopted, and the cotton and polyester are separately opened and cleaned, that is, the color polyester and white polyester are separately opened and cleaned by carding, and the natural cotton is separately combed. And then mix and match on the draw frame.
