SARAGEN-SO

Saragen-SO | Dispersing Agent for Polyester

Product Information

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, particularly for dark shades which are dyed for a longer period at low liquor ratio. Dyes with inferior dispersions, an 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 a washing-off agent for reactive dyes as it keeps hydrolysed and unreacted dye in solution.

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

  • Take 65 parts of DM water
  • To this, gradually add 35 parts of Saragen-SO under constant stirring using paddle stirrer at 200-300 rpm.
  • Continue stirring to obtain a homogenous product

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.

Precautions

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 : 8 months from the date of manufacturing, if stored under controlled conditions.
