Surface treatment of cotton using b-cyclodextrins sol–gel method

b-Cyclodextrin can be added into sol–gel solution which consists of 3-glycidyloxypropyl-trimethoxysilane (GPTMS), tetraethoxysilane (TEOS), catalyzer and solvent. This b-cyclodextrianto sol–gel solution is able to anchor b-cyclodextrin on cotton fabrics in gelation process in order to impart new surface property of cotton. The suitable technical conditions of forming stable b-cyclodextrin sol–gel solution were presented. b-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 functionalities were verified simply by decreasing the rate of volatile fragrance substances.
