Abstract
Biopolishing treatment, given to the cotton fabrics using cellulases, often influences dyebility and certain physical properties of the fabrics after treatments, besides improving appearance and handle values. Cellulase treatments prior to dyeing facilitate the dyeing process subsequently, while reactions of cellulases are retarded by the dyestuff present in the fabrics to different extents. Removal of protruding fibres imparts smooth appearance and defibrillation of cotton fibres alters the moisture absorption properties of the fabrics. Reduction in fabric strength, increase in elongation at break are also realized in biopolishing in addition to improved handle values. An attempt has been made to review the influential behaviour of cellulase treatment on dyeability and physical properties of cotton fabrics.
