MICROSTRUCTURE AND CAPILLARITY OF BIOMODIFIED COTTON FABRIC
Biological modification of cotton fabric cellulose was carried out with enzyme complexes of α-amylase and lipase; after that was dyed with the active dye. The microstructure of the original raw fabric, fabrics treated with the traditional soap-soda and enzymatic methods, and the dyed fabric were studied using the IR Fourier spectroscopy method. Analysis of the spectra, the amount of released sugars and the capillarity of the fabrics show that, unlike traditional processing, enzymatic processing results in a more complete removal of not only the sizing, but also the accompanying carbonyl, fatty and wax impurities from the cellulose structure. Structural changes in cellulose create favorable conditions for effective finishing of cotton fabric with an active dye
