Surface treatment of cotton using beta-cyclodextrins sol-gel method
beta-Cyclodextrin can be added into sol-gel solution which consists of 3-glycidyloxypropyl-trimethoxysilane (GPTMS), tetraethoxysilane (TEOS), catalyzer and solvent. This beta-cyclodextrianto sol-gel solution is able to anchor beta-cyclodextrin on cotton fabrics in gelation process in order to impart new surface property of cotton. The suitable technical conditions of forming stable beta-cyclodextrin sol-gel solution were presented. beta-Cyclodextrins are able to form inclusion complexes with other guest components. As a result of the inclusions, the treated fabrics achieved new functional properties by the selective inclusion of the guest substances into the fixed cavities on fabrics. A novel functional surface treatment of fabrics is presented by sol-gel methods. The new functionalifies were verified simply by decreasing the rate of volatile fragrance substances.
