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 stain. Fixation temp of these dyes is 60-650C.

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 and continue dyeing now gradually raise temp to 60-65oc and add remaining amount of predissolved Glauber’s salt after reaching 60oC temp. Continue dyeing for 15min. further, now add soda ash solution and continue dyeing for 60min. maintain temp. 60-650C and wash the material.

Semi Continous and Continous Process : This Process for ‘ME’ dyes is same as for Reactive ‘H’ Dyes.

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:

Exhaust Dyeing Process : Set dye bath at 50oC add predissolved dyestuff, enter the material and run for 15 minutes. Add half of the predissolved Glauber’s salt and continue dyeing, now gradually raise temp to 80-850C and in the mean time add remaining amount of predissolved salt and continue dyeing for 10 minutes further after attaining temp. 80-850C now add soda ash solution and continue dyeing for 30-60 minutes maintain temp. 80-850C 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 dyeing raise the temp to 80-850C in the mean while add remaining amount of predissolved glauber’s salt and continue dyeing till temp 80-850C now add soda ash solution and, Continue dyeing for 30-60min. maintaining temp 80-85oC and wash the material.

Semi Continous and Continous Process: This Process for ‘HE’ dyes is same as for Reactive ‘H’ Dyes.
