Scouring of Okra Bast Fibre
The removal of impurities such as dirty materials, fatty, waxy and gummy substances from textile materials is called scouring. It is carried out by the use of surface-active agents, such as soda and detergents.
About 30 cm from the bottom of the fibre was discarded and it was then cut into three equal parts (20 cm) viz. the top, the middle and the bottom. Middle portion of the fiber was used for investigation. Okra bast fibre was scoured in a solution containing 5 mg Na2CO3 and 5 gm detergent per liter of water in a large beaker. The ratio of the fiber to solution was 1:50. The solution with okra fibre was heated at 60°C for 30 min. Then the fiber was thoroughly washed with distilled water for several times. Finally it is dried at 80-90°C in an electric oven and stored in a desiccator.
