Abstract

Woven fabrics of cotton, on the warp threads are coated with an adhesive sizing agent to prevent the threads from breaking during weaving process. Starch and its derivatives are the most common sizing agents. After weaving, starch must be removed in order to prepare the fabric for dyeing and finishing. This process is called as desizing and it include the use of chemicals such as acids, alkalis and oxidising agents with traditional process. Because of that in the world are carried out investigations to replace conventional chemical textile processes by eco-friendly and economically attractive bioprocesses using enzymes. This paper will show the experimental results relating to the selection of the enzyme and process optimization made in order to increase the content of glucose in the desizing liquor of starch sized cotton fabric. The results showed that the commercial desizing enzyme preparations of α-amylase enzymes were not appropriate to produce a large quantity of glucose, and whilst used commercial food amyloglucosidase preparation, produced a large quantity of glucose after the optimization process.
