Reactive Dyes

ME dyes are low temp. high exhaust reactive dyes suitable for dyeing, padding

and printing of all types of cellulosic material These dyes offer high grade of all

round fastness properties. They offer excellent levelling properties and excellent

alkali stability. These dyes gives exceptionally good result on various textile

printing including on discharge printing except RED which gives slight yellowish o

stain. Fixation temp of these dyes is 60-65 C.

Exhust Dyeing Process :

Set dye bath at room temp. add predissolved Glauber's salt, now enter the

material and run for 20 minutes, add half amount of predissolved Glauber's salt oand continue dyeing now gradually raise temp to 60-65 c and add remaining

oamount of predissolved Glauber's salt after reaching 60 C temp. Continue

dyeing for 15min. further, now add soda ash solution and continue dyeing for o

60min. maintain temp. 60-65 C and wash the material.

These are named as 'Hot Brand Dyes'. These dyes are applied under strong

alkaline condition at high temp of application compared to cold brand dyes.

These dyes contains very good fastness properties. These dyes are suitable

particularly for printing, cotton, Viscose, Cuprammonium rayons & natural silk.

Dyeing process of these dyes is as below:

Semi Continous and Continous Process : This Process for 'ME' dyes is same as for

Reactive 'H' Dyes.

1. BIFUNCTIONAL DYES ('ME' DYES)

2 . CYANURIC CHLORIDE BASED HOT DYES ('H' DYES)

add remaining amount of predissolved salt and continue dyeing for 1 0 minutes o

further after attaining temp. 80-85 C now add soda ash solution and continue odyeing for 30-60 minutes maintain temp. 80-85 C and wash the material.

These dyes are suitable for deying cotton & other Cellulosic material. These dyes

posses significantly higher exhaustion & fixation efficiency which results in

appreciable cost reduction in comparison to other conventional reactive dyes.

The high fixation and good buildup are of particular importance when dyeing

polyster/cellulosic blends where liquor to material ratio is quite high. Due to

higher fixation of reactive HE dyes, the drained and wash luquors after dyeing

contain much less quantity of unfixed dyes in comparison to conventional

reactive dyes. This facilities quicker wash off and efficient soaping. The

improved stability of HE dyes gives improved batch to batch consistency.

Exhaust Dyeing Process :

Set dye bath at 50oC and add predissolved dyestuff, enter the material and run

for 15 minutes now add half of the predissolved glauber's salt and continue o

dyeing raise the temp to 80-85 C in the mean while add remaining amount of opredissolved glauber's salt and continue dyeing till temp 80-85 C now add soda

oash solution and, Continue dyeing for 30-60min. maintaining temp 80-85 C and

wash the material.
