DEKsol reactive dye printing methods
I. Preparation fo sodium alginate paste
1. Prescription
Sodium alginate (dry powder) 6-8kg
Sodium hexametaphosphate 0.5kg
Water x kg
───────────────────────────────
Total synthesis 100 kg
2. Preparation
Fill the barrel with warm water, add sodium hexametaphosphate. Slowly add sodium alginate powder to the water while stirring. Add water to the total volume after there is no granular. Use soda ash or acetic acid to adjust the pH value to neutral. Cooling backup.
II. Preparation of printing paste
1. Prescription
Dye x kg
Urea 5-10kg
Reserve salt S 1 kg
Baking soda 1.2-2.5kg
Water y kg
Sodium alginate paste 40-50kg
────────────────────────────────
Total synthesis 100 kg
2. Preparation
First, use a small amount of cold water to mix the dye into paste, add pre-dissolved urea and reserve salt S, then add hot water to fully dissolve the dye. Add paste and mix evenly. Add baking soda solution to the printing paste before use.
III. Printing process
Printing-Fully drying-Steaming (102-105℃, 5-7min)-Cold water washing-Hot water washing-Soap boiling-Hot water washing-Cold water washing-Drying。
