520.3.#.a: Two forms of pollutants are usually discharged from scouring of wool fleece; namely the effluent liquid phase and the solid phase. These phases comprise a significant quantity of wool wax which would be a suitable candidate for valuable products and applications. This work is devoted to extraction, recovery, and characterization of lanolin from wool fleece from different sheep breeds to assign possible ways for its utilization in the textile field. The results show that the amount of wool wax extracted from coarse wool fleece as well as its chemical composition and physical properties are almost similar to those extracted from other finer wool fleece. The aim of this work is further devoted to separation and characterization of fatty acids (FAs) from the extracted wool wax. The separated wool FAs were esterified with poly ethylene glycol (PEG) to obtain a condensate which was utilized as a nonionic softener for wool. The alteration in morphology of the coated wool fabric was assessed using scanning electron microscopy. The results revealed that the WFA/PEG-coated fabrics exhibit reduced surface roughness and improved resistance to felting shrinkage during mechanical agitation.

Resumen
Two forms of pollutants are usually discharged from scouring of wool fleece; namely the effluent liquid phase and the solid phase. These phases comprise a significant quantity of wool wax which would be a suitable candidate for valuable products and applications. This work is devoted to extraction, recovery, and characterization of lanolin from wool fleece from different sheep breeds to assign possible ways for its utilization in the textile field. The results show that the amount of wool wax extracted from coarse wool fleece as well as its chemical composition and physical properties are almost similar to those extracted from other finer wool fleece. The aim of this work is further devoted to separation and characterization of fatty acids (FAs) from the extracted wool wax. The separated wool FAs were esterified with poly ethylene glycol (PEG) to obtain a condensate which was utilized as a nonionic softener for wool. The alteration in morphology of the coated wool fabric was assessed using scanning electron microscopy. The results revealed that the WFA/PEG-coated fabrics exhibit reduced surface roughness and improved resistance to felting shrinkage during mechanical agitation.
