Abstract: In order to bring some special factions to cotton fabric, soluble β-cyclodextrin prepolymer (β-CDP) was prepared in an alkaline medium. It was grafted onto cotton fiber by citric acid （CA）as a crosslinking agent and sodiun hypophosphite （SHP）as a catalysts at the temperature of 160~180℃. The effects of factors such as concentration of CA, β-CDP and SHP, curing temperature and time on the properties of finished fabric were studied. The optimum conditions were β-CDP 30g/L, CA 50g/L, SHP 30g/L, cured at 180℃ for 2.5min. The results showed the ability of finished cotton fabric to include and release fragrance was improved, the whiteness and breaking strength were also improved slightly.
