 Full text | Abstract: A series of Si/Ti composite nanosols were prepared to improve the wash fastness of six different coloured direct dyes. As a result Si/Ti composite sols with molar ratios of 14:1 are recommended as the most appropriate recipe. When dyed fabrics were treated with Si/Ti composite nanosol by the traditional pad-dry-cure process, the gel particles linked together in -Si-O-Ti-O-Si- bonds to form a compact inorganic-organic hybrid network, as observed in SEM pictures; the wash fastness of direct dyes on the cotton fabric had obviously improved. The strength and handle of the fabrics treated also showed no negative effects with the suitable recipe. |
