Lustrous dyed pattern effects are imparted to fabrics by subjecting them to treatment with a component capable of combining with a diazo compound to form the dye, printing the treated fabric with an aqueous composition comprising a resin which is insoluble in water when set, a diazo compound, a thickener and a lubricant, drying the fabric to dampness, and then subjecting it to friction glazing to impart lustre to the printed area and to institute curing of the resin. In a modification, the fabric is first treated with an aqueous solution of a diazotizable dyestuff which is then diazotized, printed with an aqueous solution comprising a resin which is insoluble in water when set, a coupling component for the diazotized dyestuff, a thickener and a lubricant, and is then dried to dampness and friction glazed. When the coverage of the pattern is less than about 80 per cent, the fabric is pre-sized with a sizing solution imparting substantially the same frictional characteristics as those imparted by the printing solution. In examples: (1) cotton is impregnated with a solution containing Naphthol AS, sodium hydroxide, olein oil and ammonium alginate, dried, printed with a paste containing urea - formaldehyde resin, melamine-formaldehyde resin, tragacanth, olein oil, Fast Red Salt AL and Fast Red Salt 3GL, damp dried, glazed at 325 DEG F. and cured at 300 DEG F.; (2) cotton is impregnated with a solution containing Naphthol AS, caustic soda, yellow dextrin and polyethylene glycol, dried, printed with a paste containing polyvinyl alcohol, formaldehyde, olein oil, Variamine Blue Salt BD, and ammonium thiocyanate, damp dried, glazed at 350 DEG F. and cured at 320 DEG F.; (3) fabric is impregnated with a solution containing Naphthol AS-RL, caustic soda, olein oil and ammonium alginate, dried, printed with a paste containing urea-formaldehyde resin, tragacanth, olein oil, ammonium thiocyanate and Fast Scarlet Salt 2G, damp dried, glazed at 350 DEG F. and cured at 300 DEG F.; (4) cotton is impregnated with a solution containing Naphthol AS, caustic soda, olein oil and yellow dextrin, dried, printed with a paste containing Fast Red GL Base, hydrochloric acid, sodium nitrite, sodium acetate, melamine-formaldehyde resin, tragacanth, sulphonated castor oil and ammonium thiocyanate, damp dried, glazed at 340 DEG F. and cured at 320 DEG F.; and (5) cotton is dyed with Diazo Sky Blue-BA New, diazotized, dried, printed with beta-naphthol, caustic soda, acetone-formaldehyde resin, sulphonated olein oil and tragacanth, damp dried, glazed and cured at 340 DEG F.ALSO:Lustrous dyed pattern effects are imparted to fabrics by subjecting them to treatment with a component capable of combining with a diazo compound to form a dye, printing the treated fabric with an aqueous composition comprising a resin which is insoluble in water when set, a diazo compound, a thickener and a lubricant, drying the fabric to dampness and then subjecting it to friction glazing to impart lustre to the printed area and to institute curing of the resin.
