Carrier and vessel washed by hydrose and caustic at 1000 C for 20 min

Load the package in the carrier and feed in the vessel

Add wetting agent, anti foaming agent, sequestering agent and run at 600 C for 10 min

Water solution drain

Add wetting agent, sequestering agent, caustic soda and hydrogen peroxide and run at 1100 C for single yarn and 1150 C for double yarn for 20 min

Drain

Add peroxide killer and run at 900 C for 10 min

Peroxide check in the package
