They are cheap, generally have good wash-fastness and are easy to apply.

During this process these dyes form complex larger molecules which is the basis of their good wash-fastness. 5.Payment &Delivery Payment terms:L/C, T/T,30%DEPOSIT+70%BEFORE SHIPMENT Delivery:With 15 days after received 30% deposit.
