The conventional plain color fabric is to weave the embryo cloth with white yarn, and then dye it to form the fabric with single cloth color. Pure cotton yarn dyed fabric is woven from dyed pure cotton yarn. The finished product can be finished without dyeing process and direct finishing. Compared with printing and dyeing plain cloth, pure cotton yarn dyed fabric has a unique style: it can form different styles such as large color strips, small color strips and jacquard color strips. Because the total loss of dyeing, weaving and finishing of pure cotton yarn dyed fabrics is relatively large, and the machine output is not as high as the output value of white cloth, generally speaking, the fabric cost of yarn dyed fabrics is slightly higher than that of pure yarn dyed fabrics.
