If the grey fabric is of good quality in production, the dyeing rate will be high and the dyeing will be good, and the fabric surface will be smooth and even and plump; if the grey fabric is of poor quality, the dyed white star and fabric noodles will be severely bloomed. Therefore, when encountering grey fabrics with a lot of dead cotton and cotton, it is necessary to strengthen the pre-treatment process, while ensuring the safety and reliability of production, try to clean the cotton as much as possible, boil the dead cotton through, and improve the dye uptake and the quality of the dyed fabric.
