Preparation and characterization of lanolin-based condensate and its utilization as a nonionic softener for wool fabric surface

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