Washing & Soaping
After Dyeing it is necessary to remove the unfixed Dye to get a high level of wash fastness. It is also essential to remove the residual Salts and Alkali prior to soaping. The usual sequence is:
- Washing with cold water.
- Washing with hot water not above 60 °C.
- Soaping at boil for 15~30 minutes using 1-2 gm/lit of lissapol D.
- Rinsing with Warm Water at 50 °C.
- Rinsing with cold water, till squeeze water is clear.

Process
Mix dye powder with urea and pour hot water of temperature about 80-85°C and stir well to dissolve completely. Add this dye solution to sodium alginate thickening paste containing resist salt stir well to mix. Just before printing add sodium bicarbonate.
Print the cloth with above print paste and dry. Avoid over-drying and protect printed goods from acid or reducing fumes. Then steam dried goods for 5-8 minutes on rapid ager or 15-20 minutes on star ager.
