Scouring of Man Made Fiber

Man made fiber are comparatively free from impurities and so much milder methods of scouring are applied for them,

1. Nylon:

i. Synthetic detergent = 1.5-2 parts/L.

ii. Sodium Carbonate = 0.5-1.5 parts/L.

iii. Washing start temperature = 20-30ºC (Normal).

         = 70-80ºC (Non-heat set).

         = 90-100ºC (for heat set).

2. Acrylic fiber: 1% Non ionic detergent temperature 80ºC.
3. Rayon/Viscose:

i. Soap/Detergent = 0.3%.

ii. Na₂CO₃ = 1%.

iii. Temperature = 80-90ºC.

Acrylic fiber is the main element of our sweeter.
