A method for the process of dyeing with reactive dyes is to provide,
- i. the affinity of the dyestuff, acceleration of the dyestuff association and exhaustion of dyestuff for migration and adsorption using the salt mixture as an electrolyte comprising the following (Weight percentage of content basis):
- A. potassium chloride between 2% and 50%
- B. diammonium phosphate between 0.5% and 18%
- C. urea between 0.9% and 60%
- D. sodium nitrate between 2.00% and 30%
- E. calcium chloride between 0.02% and 7%
- F. manganese sulphate between 0.10% and 5%
- G. ETDA sodium between 0.002% and 7%
- H. Ferrous sulphate between 0.10% and 10%
- and the balance water and a mixture thereof, ranging between 0.2 and 5 GPL (gram per litre) with 0.5 to 5 GPL of sodium chloride or sodium sulphate in reactive dyeing wherein the pre-treated cellulose material maintained with a pH 3 and above, at an (MLR) material to liquor ratio maintained between 1:20 and 1:3 at a temperature between 25° C. and 80° C. and exhausted for between 15 minutes and 90 minutes,
- ii. the fixation of dyestuff using alkali agent I comprising the following (Weight percentage of content basis)
- A. sodium bicarbonate between 2% and 40%
- B. potassium bicarbonate between 0.5% and 15%
- C. sodium carbonate between 10% and 90%
- D. potassium carbonate between 2% and 70%
- E. sodium acetate between 2% and 30%
- F. ferrous sulphate between 0.1% and 5%
- and the balance water and a mixture thereof, ranging between 0.5 and 15 GPL (gram per litre) in reactive dyeing wherein the exhausted cellulose material maintained with a pH between 9.5 and above, at a temperature between 25° C. and S0° C. and stained for between 10 minutes and 90 minutes.
- iii. further, for more fixation of the dyestuff using alkali agent P comprising the following (Weight percentage of content basis)
- A. potassium hydroxide between 5% and 70%
- B. calcium hydroxide between 1% and 50%
- C. trisodium phosphate between 2% and 80%
- D. sodium hydroxide between 0.1% and 20%
- and the balance water and a mixture thereof, ranging between 0.2 and 10 GPL (gram per litre) in reactive dyeing wherein the stained cellulose material maintained with the pH between 10 and above at a temperature between 25° C. and 80° C. and again stained for 40 minutes and 150 minutes and thus end with neutralization, soaping, washing well with hot water then water and at last drying and further to provide excellent dyeing, perfect levelling property, better colour, fastness to washing and rubbing, lower COD, BOD and TDS, less consumption of water, energy, time and man power and safe environment.
