Abstract

<span style="font-size: 9.0pt;mso-bidi-font-size:11.0pt" lang="EN-GB">Biological treatment of textiles has become a preferred choice over chemical treatment because of it being less harmful to textiles and environment. Bio-polishing refers to the treatment of cellulose-containing textile fabrics with cellulase enzyme for removing protruding fibers in order to achieve a smooth and polished surface. The purpose of this study was to produce a cellulase enzyme from <i style="mso-bidi-font-style:normal">Aspergillus niger </i>and find out optimum conditions for its application in bio-polishing of polyester/cotton blended fabric. It was observed that the produced cellulases exhibit optimum activity at pH 5.0 and 55°C temperature. The enzyme activity/concentration may be varied during bio-polishing for achieving the desired degree of bio-polishing on polyester/cotton blended fabrics.
