Grey Melange yarn is the special types of yarn. The fabric which is made from the grey melange yarn is also special. Here I have given a dyeing flow chart by which grey melange yarns are dyed. After dyeing grey melange yarns are used for producing woven and knitted fabrics. Dyeing also done for grey melange fabric but basic dyeing sequence is same.
