PRODUCT LITERATURE

POLYDYE-DIF

Product Information

Polydye-DIF is a levelling, dispersing agent for dyeing of polyester and its blends with disperse dyes. It has also a diffusion property thereby helps to reduce dyeing time. It improves dispersion stability of the dyes in the bath, prevents agglomeration and deposition of oligomer on the fabric and keeps machine clean.

Polydye-DIF has a migrating property thereby it corrects faulty dyeing. Polydye-DIF improves exhaustion of dye specially for polyester microfibre which permits dyeing in short liquor ratio. Polydye-DIF is particularly suitable for the reverse fast method for dyeing of polyester / cellulosic blends.
