Introduction

POWSIL-99170 is a hydrophilic and very stable textile softener based on an anionic system which has excellent compatibility with most of pretreatment and finishing chemicals used. It can be applied in pretreatment process to prevent fabric from being creased and texture damaged during movement in tank. It also can be applied in finishing stage to prevent fabric from oil-spots

Application

POWSIL-99170 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-99170 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.

1. Pretreatment Conditions

POWSIL-99170:	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-99170 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.

2. 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

3. Garment washing process:

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

Stripping:

1. Formulation for stripping off cotton fabric:

5-10 g/L NaOH
2-3 g/L SDBS (Sodium Dodecyl Benzene Sulfonate, 30%)
Water

2. Formulation for stripping off polyester fabric

5-10 g/L Na₂CO₃
2-3 g/L Alcohol ethoxylated with 10 EO

3. 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

Packing and Storage

To ensure that the product quality is maintained, the container should be tightly sealed when not in use. It should be stored at normal room temperature, preventing prolonged exposure to extreme heat and cold conditions, which may cause product separation. POWSIL-99170 tends to be sediment on bottom during storage period. If the product is separated, stir the contents to homogeneous. If the product is frozen, thaw it at warm condition and stir after thawed.

POWSIL-99170 is packaged in net weight 120Kg plastic drum.
