Effects of biopolishing on the quality of cotton fabrics using acid and neutral cellulases

The aims of the study were to analyze the treatment conditions for the use of acid and neutral cellulase enzymes and evaluate the changes in the various properties of the treated fabrics. In this study, biopolishing was carried out on bleached fabric using acid cellulase (Mega PK) and neutral cellulase (Mega L-1009D) considering three factors: concentration (0.5, 1, and 1.5 %), temperature (45, 55, and 65 °C), and time (40, 50, and 60 min). Changes in the physical properties such as weight loss, strength loss, pilling resistance, abrasion resistance (mass loss), and bending length of the biopolished fabrics were measured. Using Mega PK, weight loss and strength loss were found within 0.25 to 1.42 % and 1.7 to 24.7 %, respectively, while these values were found within 0.20 to 1.22 % and 1.5 to 18.9 %, respectively, using Mega L. On the other hand, pilling and abrasion resistance of the fabrics were improved due to biopolishing. In addition, bending length was found maximum 31.62 % lower than the untreated bleached fabric using Mega PK and 44.26 % lower using Mega L. It was also concluded that 1 % Mega PK showed better results when applied at 55 °C for 40 min, whereas 1 % Mega L showed better results when applied at 55 °C for 50 min among all the treatment conditions.
