Hydrophilic Silicone Softener Emulsion

Technical Data

Application

• POWSIL-59170 silicone softener for textiles can be applied in pretreatment process to prevent fabric from creases  and texture damage caused by fabric scratching during fast movement in tank. It is  compatible with most scouring agents and hydrogen peroxide (H₂O₂ ).

• POWSIL-59170 can be used as received or pre-diluted with water before applying and the desirable usages are dependent on the required softness of the fabric or yarn.

• Pretreatment Conditions

  POWSIL-59170:	0.5-2.0% (o.w.f)
  NaOH(30%):	3-5% (o.w.f)
  H2O2(27.5%):	6-8% (o.w.f)
  Liquor ratio:	1/10 - 1/20
  Temp.:	98°C
  Time:	20-40 mins

  POWSIL-59170 can also be applied in the finishing stages as a stable softener to prevent oil-spots on fabric with both in bath-padding and exhaustion.

  
  

• For Finishing Process

  
  

  Pad-dry-cure process

  Dosage:	5-10 g/L (light fabric) – 10-20 g/L ( heavy fabric)
  Temp.:	20 - 40°C
  Pick-up:	65 - 85%
  Drying:	100 – 130°C for 2min
  Curing:	100 - 200 ºC for 1 - 3 min

  
  

• Exhaustion process:

  Dosage:	0.5 – 2.0% (o.w.f)
  Liquor ratio:	1/10 - 1/20
  Temp.:	30 - 50 °C
  Time:	20 - 30 min
  Drying:	100 - 130 ºC

  
  

• Garment washing process:

  
  

  Dosage:	0.5 -2.0% (o.w.f)
  Condition:	Same as exhaustion process

• Stripping:

  
  

• Formulation for stripping off cotton fabric:

      -5-10 g/L NaOH

      -2-3 g/L SDBS (Sodium Dodecyl Benzene Sulfonate, 30%)

      -Water

• Formulation for stripping off polyester fabric

      -5-10 g/L Na₂CO₃

      -2-3 g/L Alcohol ethoxylated with 10 EO

• Procedures for stripping off:

  - Charge fabric and water into machine

   - Add NaOH for Cotton fabric or Na₂CO₃ for polyester fabric

   - Heat to 98-100 °C and continue to boil for 30-60 min

   - Cool down and rinse fabric with water
