Dyeing Method
Procedure for Dyeing with V.S. Base Reactive Dyes by Exhaustion Method
Enter the Goods to be dyed in dyebath then heat up to 80° C within 20 -30 minutes. Then Requisite Quantity of soda ash is to be added and continue the dyebath for 1 hour at 80° C. Then Wash Off Goods with cold and soaped boil water simultaneously. Again it is required to wash with cold water. Then Dry the goods
Salt and Alkali Requirement.
| Depth of Shade | Salt Gmsll | Soda Ash Gmsll |
| 2.0 % | 50 | 5 |
| 4.0 % | 80 | 5-10 |
Procedure for Printing with V.S. Base Reactive Dyes
Finally made 1000 parts with alginate thickening. Firstly dissolve Urea is dissolved in water at 80° C. Then add Dyestuff & Stirr to dissolve. Then add resist salt, Sodium bicarbonate and thickening. This is to be stirred to homogenous paste. After printing the goods are to the dried, steamed for 15 -20 minutes. Then wash off goods with cold and soaped boil water simultaneously. Again it is required to wash with cold water. Then dry the goods.
Preparation of Printing Paste by steam process.
| Dyestuff | 10 - 40 parts |
| Urea | 04 - 10 parts |
| Hot Water | 100 - 200 parts |
| Resist Salt | 10 parts |
| Sodium Bicarbonate | 10 - 25 parts |
Discharge Printing on Cellulosic Goods
Print on Dyes good after treated with mild oxidicing agent. Dried and steam at 103° C. in Rapid ager for 10 minutes. Then wash off as usual.
Preparation of Discharge Print Paste
| Rangolite C | 10 - 15 parts |
| Glycerine | 2 |
| Caustic Soda ( 70 TD ) | 15 parts |
| Leucotrope W | 5 parts |
| Titanium Dioxide ( 1:1) | 10 parts |
| Rest Thichening 100 Part | 100 parts |
Process for Dyeing with 'H' Brand Reactive Dyes by Exhaust Method
Take requisite quantity of dye and salt in the dyebath at 40° C. Enter the goods to be dyed in dyebath then heat up to 80° C. within 20 -30 minutes. Then add Soda ash and continue the dyebath for 1 hour. Then wash off the goods with cold and soaped boil water simultane ously. Again it is required to wash with cold water. Then dry the goods.
Preparation of Discharge Print Paste
| Depth of Shade | Salt Gms/l | Soda Ash Gms/l |
| Up to 0.5 % | 40 | 20 |
| 0.5 % to 2.0 % | 60 | 20 |
| 2.5 % to 4.0 % | 80 | 20 |
| Above 4 % | 100 | 20 |
Process for Printing with 'H' Brand Reactive Dyes
Finally make it to 1000 parts with alginate thickening. The Printing Procedure is same as V.S. Base Reactive Dyes
Preparation of printing paste by steam process.
| Dyestuff | 10 - 50 parts |
| Urea | 100 - 150 parts |
| Water | 100 - 365 parts |
| Resist Salt | 10 parts |
| Sodium Bicarbonate | 10 - 25 parts |
