  Abstract

The modification of wool fabrics is significant in preparation of functional textiles. Sodium periodate oxidized 棺- cyclodextrin was grafted onto wool fabric through Schiff base reaction to obtain fabric with controlled release property. 棺- cyclodextrin was oxidized to aldehyde-棺-cyclodextrin, and the results show that the inclusion constant and aldehyde content of aldehyde-棺-cyclodextrin are varied with the reaction parameters such as molar ratio of reaction agents and the reaction temperature. The degree of oxidation was confirmed by ion chromatography. The drug loading test shows that the oxidized cyclodextrin still had inclusion ability towards phenolphthalein, while the inclusion constant was only 50 % of the original 棺- CD. The ATR-FTIR spectra proved the occurrence of grafting reaction between the aldehyde groups of aldehyde-棺- cyclodextrin and the amino groups on wool fiber. The aldehyde-棺-cyclodextrin grafted wool fabric show great washing durability even after 5 washing cycles. Compared with the aldehyde-棺-cyclodextrin power, the inclusion ability of aldehyde- 棺-cyclodextrin fixed on the wool fiber decreased by 60 %.
