- Definition water-insoluble greasy material secreted by the sebaceous glands in sheep skin and adhering to the wool Reference 'A Simplification of Textile Waste Survey and Treatment' (8.9.2022). New England Interstate Water Pollution Control Commission by Wesleyan University (Middletown, Conn.). 1959
- Comment 1)In addition to wool fibre, 'raw wool' contains the impurities listed below:- 'Wool grease' 2-25 % of greasy wool weight- 'Suint' (dried perspiration) 2-12 % of greasy wool weight- Dirt 5-45 % of greasy wool weight- Residues of insecticides, acaricides or insect growth regulators used as veterinary medicines to protect sheep from ectoparasites, such as lice, mites, blowfly, etc.Wool grease is insoluble in water, but soluble in non-polar solvents such as dichloromethane or hexane. Refined wool grease is a valuable by-product.Suint is water-soluble material arising from the secretion of the sweat glands in the skin. Suint is soluble in polar solvents such as water and alcohol.Dirt can include a variety of materials such as mineral dirt, sands, clay, dust and organic materials.In the scouring bowls, suint is removed from the wool by dissolution, grease by emulsification and dirt by suspension.Wool grease has a melting point around 40 °C. Since removal of solid grease from wool by detergents is slow and difficult, 40 °C is the lowest temperature at which aqueous scouring liquors are effective for removing grease.2)Chemically the compounds of wool grease are essentially waxes and not fats or greases.
