Abstract: | Contribution to the Enzymatic Degradation of Starch Sizing Agents on a Textile Fabric. In this work some experiments concerning the enzymatic desizing of cotton fabrics using cyclodextrin glucosyl transferase are discussed. It has been reported that the enzyme catalyzes the formation of β-cyclodextrin in solution. The results demonstrate that it is possible to degrade starch on a textile fabric by means of CGTase. On the present conditions the enzyme catalyzes the formation of α-cyclodextrin. More experimental work is necessary to optimize the conditions for enriching β-cyclodextrin against α-cyclodextrin. |
