Chemifix ME Dyes

Chemifix 'ME' Dyes are hetero bifunctional dyes. These dyes contain atleast one vinylsulfone and one monochlorotriazine reactive group and are mainly recommended for exhaust dyeing. These dyes can also be used in pad-batch (silicate method) and printing applications. 'ME' dyes can be used in combination with vinylsulfone dyes for producing mixture shades.

Salient Features

Suitable for exhaust dyeing at 60°C
Possible to produce deepest shades
Very much economical for medium and dark shades
Excellent shade build-up

Exhaust Dyeing

Winch/Jet Dyeing

Start dyeing with required amount of dye at room temperature. Run the fabric for 10 min. Add the required amount of salt in 2-3 portions over a period of 20 min. Continue dyeing for 15 min. at room temperature and then add 1/5th alkali and raise temperature to 60°C in 20-30 min. and continue dyeing at 60°C for 10 min. Add remainging alkali in 2-3 portions and continue dyeing for 60-90 min.

Jigger Dyeing

Start dyeing at room temperature by adding the required amount of dye and salt over two ends. Then give two more ends and add half the amount of alkali over two ends and raise temperature to 60°C and add balance quantity of alkali over two ends and dye for further 4-6 ends, depending on the depth.

Salt and Alkali requirement

% Shade	Common Salt g/l	Soda Ash g/l
Upto 0.1	5 - 10	10
0.1 to 0.5	15 - 25	10 - 15
0.5 to 2.0	25 - 50	15 - 20
Above 2.0	60 <	20

Washing off

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

Cold rinse ------> Hot rinse ------> Neutralise (with acetic acid) ------> Soap (1-3 times) ------> Hot rinse ------> Cold rinse.

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

Pad Batch Dyeing and Printing Methods recommended for Vinlysulfone reactive dyes can be used for 'ME' dyes also.
