Wool scoured using ultrasound irradiation at intermediate stages has been analysed and compared with the wool scoured without ultrasonic energy. The conventional recipe is modified with 25% reduction in chemical concentration, time and temperature. The scouring efficiency is measured in terms of residual grease content. Ultrasound energy effectively removes grease with lower concentration of chemicals, temperature and time. Ultrasound subjected to all bath scouring has lowest residual grease content. However, the highest improvement in whiteness is observed during ultrasound irradiation on rinsing baths. It is also observed that the combination of ultrasound and alkali adversely affects whiteness and yellowness. Scanning electron microscope analysis shows no cuticle damage after ultrasound exposure on wool fibre. In addition, the chemical properties of wool are not changed due to ultrasound treatment. The mean fibre diameter, single fibre strength and moisture content do not show significant change after ultrasound irradiation.
