Abstract: For reducing the vapor pressure of volatile fragrances oil and increasing fragrance retention in functional textiles,fragrant finishing of cotton fabric is performed with lavender oil via inclusion technology using-βcyclodextin which has unique molecular structure and inclusion nature.The inclusion has been realized by immersion method under orthogonal experimental conditions.The influence of inclusion conditions on the ability of inclusion of-βcyclodextin has been studied.The lavender oil absorbed by-βcyclodextin is extracted by Soxhlet and its quantity is determined by the UV/VIS spectrometer.The results showed that the optimized inclusion conditions as follows: inclusion time 2 h,temperature 30℃,pH value 9 and quality proportion between alcohol and water 1∶1.Under optimized conditions,lavender oil included by-βcyclodextrin reaches up to 81.65% of-βcyclodextrin on the cotton fabric grafted by 5%-βcyclodextrin,this shows that the ability of inclusion of-βcyclodextrin is satisfactory.
