Saragen-SO is dispersing agent recommended for exhaust dyeing, direct style of printing and continuous dyeing of polyester and its blends. Saragen-SO improves dispersion stability, particulary for dark shades which are dyed for longer period at low liquor ratio. Dyes with inferior dispersions, addition of Saragen-SO in dyebath improves dispersion. Saragen-SO can also be added in print paste as well as for dyeing of disperse dyes by padding. Saragen-SO also used for washing-off agent for reactive dyes as it keeps hydrolysed and unreacted dye in solution.

1. Saragen-SO : 0.3-0.8 g/l
2. Saragen-SO for a washing-off agent. 0.3-0.5% Saragen-SO
Sequence of addition :
1. After dyeing drain the bath.
2. Add Saragen-SO at room temperature or at dyeing temperature (at 55-60 deg.C or 80-90 deg.C) for 20 min. Drain
3. Add 0.5% Celldet-R (wetting agent) increase temperature to 95 deg.C for 20 min. Drain
4. Hot rinse at 70 deg.C for 10 min, followed by a cold rinse. Drain
5. Cold rinses and carry out dye-fixing in the same bath.
Instructions For Dilution
Procedure to prepare 35% Saragen-SO
Preservation: It is recommended to add 0.1% Bronopol (2-Bromo,2-nitropropane, 1,3-diol) or Methyl Paraben (methyl para hydroxy benzoate) as an antimicrobial agent to avoid fungal/microbial growth.
It is advisable to utilize the diluted product within 2 months. Stir well before use.
Storage : Store in cool, ventilated shed away from heat and direct sunlight. Storage temperature should not exceed 35 deg C.Close lids firmly to avoid contact with air and moisture.
Shelf Life : 9 months from the date of manufacturing, if stored under controlled conditions.
