A series of sols were prepared from selected silane derivatives. When dyed cotton was treated with such sols, the colloidal particles linked together to form a network on the fibre. Thus the direct dye was fixed on cotton and the wash fastness was enhanced. This new method, based on the sol–gel process, was rudimentarily proved to be an effective way to improve the wash fastness of direct dyes on cotton without essential loss of properties, such as handle and strength of the fabric.
