A study of ultrasonic scouring of greasy Australian wool
This paper examined the application of ultrasonic agitation in conventional non-ionic detergent wool scouring. Wool samples with different mean fibre diameters were selected and subjected to various scouring times and temperatures with and without ultrasonic agitation. Scouring efficiency was assessed in terms of grease content, fibre whiteness, scouring yield and fibre entanglement. The scoured fibres were also examined under a scanning electron microscopy to evaluate the effect of ultrasonic agitation on the fibre surface structure. Ultrasonic agitation was seen to significantly improve the removal of grease from the wool fibre. Lower detergent concentrations could be used with ultrasonic agitation and still achieved the same level of scouring as conventional scouring. Lower scouring temperatures of 50℃ were feasible with ultrasonic agitation for 22 micron fibres. Ultrasonic agitation produced virtually no fibre entanglement during scouring. The fibre surface was modified by ultrasonic agitation causing moderate cracking of the fibre cuticle. The fibre cracking increased the rate of pre-metalised dye pick up at 40℃.
