Exhaust Dyeing

Jet Dyeing Method

Start dyeing at 40 C with the required amount of dye. Run the machine for 10 minutes and add 1/5th amount of salt and start raising temperature to 80-85 C, @ 1 0 C/min. During this period add remaining salt progessively in 3 portions over a period of 30 minutes and continue dyeing at 80-85 C for 20 min. and then add soda ash in 2-3 portions over a period of 20 min. and continue dyring for 60-75 min.

Jigger Dyeing Method

Start dyeing at 80-85 C by adding the required amount of dye over two ends. Then add required amount of salt over two more ends and give two additional ends. Then add alkali over ends and dye for further 4-6 ends, depending on the depth. Drain the bath and subject the fabric to usual washing off treatment.

Salt and Alkali requirement

Upto 0.1 5 - 10 10 5 0.2
0.1 to 0.5 15 - 35 10 5 0.2
0.5 to 2.0 35 - 60 15 5 0.2 - 0.5
2.0 to 4.0 70 20 5 0.5
Above 4.0 % 90 20 5 0.5

Washing off

To achieve best possible fastness properties. it is essential to remove the unfixed/hydrolysed dye completely from fabric. Following sequence can be used for this purpose:

Cold rinse -------> Hot rinse -------> Soap (1-3 times) -------> Hot rinse -------> Cold rinse

Soaping can be done with 1-2 g/l anionic or non-ionic detergent at boil for 15 min. ( M:L 1:15 to 1:20 )
