Tannin treatment of sheep wool
Original language description
The aim of this study was to test the possibility of treating raw sheep wool with tannic acid. This treatment improves the odor of sweat wool and gives the wool antibacterial properties. The tests also suggest the possibility of anti-felt treatment. To achieve these aims, tannic acid was used as strong antioxidant. The sensory evaluation of raw wet sheep wool smell before and after tannin treatment was provided by a group of 30 assessors. This subjective assessment was supplemented by an indicative measurement of volatiles using gas chromatography. Antibacterial properties of tannic acid were evaluated by the method when eluates of treated and untreated wool were cultivated on the agar medium. The antibacterial effect of tannin has been manifested in growth of different number of bacterial colonies. Finally, electron microscope images showing some damage to wool fiber surface indicated the possibility of anti-felt treatment by using tannic acid. All results suggest that tannic acid could be an effective and ecological means of raw sheep wool treatment for use in the building or automotive industry.
