Frequently Asked Questions | FAQs

What is dischargeabilty of dye?

The dischargeability of a dye refers to its ability to be removed or “discharged” from a dyed fabric or material. In textile dyeing, discharge printing is a technique used to remove color from specific areas of a fabric in order to create patterns or designs.
Some dyes are more dischargeable than others, depending on their chemical composition and structure. Dischargeable dyes typically contain reactive groups that can be chemically modified or removed under specific conditions, such as exposure to reducing agents or high temperatures.
Dischargeability can also depend on the type of fabric or material being dyed, as well as the dyeing process used. It is an important consideration in the textile industry, as it can affect the quality and durability of the final product.
