Polyester Dyeing
Polyester is the most used synthetic fiber in the world. However, this fiber is dyed with disperse dyes. If we want, we can dye the fiber during yarn preparation. Also, we can dye the yarn after yarn preparation and in fabric form. The fastness properties of polyester dyed yarn are excellent. Day by day the use of synthetic fiber increases rapidly.
