Abstract: A mixture of acid cellulase, acid pectinase and xylanase has been utilized for removing vegetable matters from lightly contaminated Egyptian wool fleece. The proposed mixture is found to be effective in removing almost all the impurities based on cellulose, pectin and lignin without attacking wool keratin or affecting its inherent chemical and mechanical properties. The effect of bio-carbonization of wool on its dyeability with acid and 1:1 metal complex dyes has been studied. Kinetic studies as well as the fastness properties of the dyed fibres to washing and perspiration have also been reported. The properties of bio-carbonized wool fibres are found to be better than those of wool fibres carbonized by conventional method using sulphuric acid.
