ABSTRACT:
A pretreatment system composed of hexamethoxymethyl melamine, p-toluene sulfonic acid, 2-amino-2-methyl-1-propanol, triethylamine, butoxy triglycol, and carboxy vinyl polymeric thickener is disclosed, which through application to the fabric surface by a screen printing technique is highly effective in improving the affinity of cellulose-containing textiles for disperse dyestuffs. Fabrics with prints that are durable to washing are produced by simultaneously heat transfer printing and curing at about 190.degree. C. to 220.degree. C. for 20-30 seconds.
