Abstract :

The first process of preparing wool is termed scouring; wool scouring is the process of washing wool in hot water and detergent to remove the non-wool contaminants and then drying it. A growing concern for the environment has led to increased demands on the scouring process as reduction in pollution has become increasingly important as the pollution load associated with conventional emulsion scouring of greasy wool is extremely high. The work done by using Cow Urine (Gomutra) as natural ecofriendly scouring agent, has changed the concept of scouring from chemical and pollution oriented one, to a chemical free, eco friendly process with other advantages. In this research cow urine was used as alkali medium with an optimized value of 150 gpl along with natural detergent SapindusSaponaria (Reetha) of 20 gpl, in five bowl system with the help of ultra sound technology for process intensification. An attempt is made of wool scouring of raw greasy wool in dry state at very low temperature in an eco-friendly manner. The dry scouring process, unlike aqueous scouring, doesn’t adversely affect the intrinsic properties of wool fibers like strength, elongation, colour, moisture regain, etc. On the contrary, the whiteness index of dry scoured wool fibers was found to be better than convention detergent and alkali based aqueous scouring process. It was observed that using this optimized recipe effluent load was reduced by 40%, without hampering the other desired mechanical properties of Wool. Also this process doesn’t hamper the dyeing property of wool.
