Study on the Tinting washing.

Tinting and over-dyeing:

The tinting and over-dyeing process is done after washing but before softening. After fading by different types of washing like acid wash, stone wash, enzyme wash, sand wash blasting, etc. The faded garments again have to dye with the little number of different dyes this dyeing process is called tinting and over-dyeing.

The function of tinting washing:

• To get the old fading effect of the garments.
• To the fulfillment of buyer requirements.
• To get desired softness.
• To over-dyeing

Dyeing Recipe:

M: L -  1:8

Dye - 0.001% to 0.005%

Salt – 15 to 20 gm/l

Soda ash – 10 to 15 gm/l

Temperature – 50 to 70˚C

Time – 20-30 min
