The Safe Softener for Finishing

SILICONE FINISHING AND REDYEING, WHY NOT?

15/11/2017

One headache problem of the Dyer is repairing the color of the fabric after finishing. The stripping of the silicone finish and redyeing after that is rather complicated and lots of risks. Our new silicone softener AVCO-ELASTOGUM RD-68 is the best choice for this case.

AVCO-ELASTOGUM RD-68 is an elastomeric polymer preparation with a built-in reactive functional end-groups.  The polymer bonds to the textile fibers into a  three-dimensional elastomeric structure. AVCO-ELASTOGUM RD-68 is designed to provide high-grade softness along with stretchy finish and bounciness to textile fabrics.

The most advantages of AVCO-ELASTOGUM RD-68 is its excellent chemical stability, which almost gets rid of silicone precipitation on padders and dyeable only after the simple wash.

Strip off for redyeing:

       Treat the fabric or garment at 90-98OC, 60 mins with below formula:

       + Avcopal VIC:           5 g/l

       + Soda ash:                5 g/l

       1 warm wash and 1 cold wash, then redye.
