The transfer printing of pretreated wool using sublimable dyes that form metal complexes on the fibre during printing is described. The most successful pretreatment involved padding a mixture of chromic chloride, an an ionic surfactant, urea and lactic acid and then drying. Low molecular-weight monoazo dyes containing salicylic acid residues, or hydroxyl or amino groups on carbon atoms in two ortho positions relative to the azo group, were screen printed onto transfer papers. Optimum heating… CONTINUE READING
