 Printing

Preparation of Fabric :

The fabric to be printed must be properly be sized to make it highly absorbent. Mercerisation of cotton fabric and custiciazation of regenerated cellulosics fabrics yield brilliant and deep prints.


Printing Operation :

Both one phase and two phase methods can be used. A typical printing recipe is given below:

Ingredients, parts	'H' Brand
Dyestuff	10-60
urea	40-60
Alginate Thickening (4.0%)	400
Resist Salt	40
Sodium Bicarbonate	15-30
Water	Balance
Total	1000

Mix the dye with urea and near boiling water for hot brand. Cool to room temperature. Add Alginate thickening and Resist Salt. Mix well Alkali is to be added just prior to printing. If necessary sieve through fine muslin cloth.

Print the cloth with above paste. Dry and steam for 15 20 minutes in continuous Ager at 100-102°C, give a cold and hot wash with water. Soap at boil with neutral soap and wash again.

 ICHOFIX^® 'ME' Dyes

• ICHOFIX^® 'ME' dyes are low temperature high exhaust Reactive dyes suitable for dyeing, padding and printing.
  
• They are applied by exhaust dyeing methods at temperature 60-65°C.
  
• They offer high grade of all round fastness properties.
  
• They have an advantage of high degree of exhaustion and fixation rates.
  
• They offer excellent leveling properties and excellent alkali stability.
  
• They give highly reproducible dyeings because of better alkali stability and low sensitivity to temperature.
