Surface modification of fabric by sol-gel method

β-cyclodextrin was anchored on fabric by sol-gel method in order to modify surface property and impart fabric new function.The effects of coupling agent and cyclodextrin on stability of sol-gel solution were discussed.The relations between temperature,dilution ratio and gel forming were presented, and the relations between the addtion method,the quantity and fastness of β-cydodextrin to be anchored on fabric were analyzed.As a result,when the dosage of coupling agent was no more than 0^05 mol/L and the adaptive temperature was between 80～120 ℃, cyclodextrin anchored on fabric may impart fabric fragrance-depositing property.
