摘要
The present invention related to a method of dyeing using the salt mixture as an electrolyte with 0.5 to 5.00 GPL of sodium chloride or sodium sulphate and alkali agents I and II to exhaust and fix the dyestuff to the cellulose material in the reactive dyeing wherein the fiber is treated with (i) the salt mixture with sodium chloride or sodium sulphate specifically, putting the pre-treated fiber maintained with pH between 3 and above and an (MLR) maintained between 1:20 and 1:3 at a temperature between 20°c and above and exhausted for between 15 minutes and above, (ii) the alkali agent I with a pH between 9.5 and above at a temperature between 30°c and above and stained for between 20 minutes and above (iii) the alkali agent II with a pH between 10.5 and above at a temperature between 30°c and above and stained for 40 minutes and above.
