Abstract
A process is disclosed for the heat transfer printing of cellulose-containing fabrics in garment form with disperse dyestuffs, wherein the fabric is treated only on one side by a printing or spraying technique with a formulation containing highly methylated melamine-formaldehyde crosslinking agent, acid catalyst, and other necessary additives. 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.
Claims10
A process for improving the affinity of cellulosic fabrics for disperse dyestuffs, the process comprising:
- (a) treating the fabric with an aqueous formulation of highly methylated melamine-formaldehyde crosslinking agent, triethylamine neutralizing agent, acid catalyst, alcoholic solvent, carboxyl vinyl polymeric thickening agent, and cationically emulsified low density polyethylene;
- (b) drying the fabric;
- and then
- (c) heat transfer printing with a transfer printing paper containing disperse dyestuff.
A process for improving the affinity of cellulosic fabrics for disperse dyestuffs, the process comprising:
- (a) treating the fabric with an aqueous formulation of highly methylated melamine-formaldehyde crosslinking agent, triethylamine, para-toluene sulfonic acid or the ammonium or magnesium salt of said acid, alcoholic solvent, and cationically emulsified low density polyethylene.
A process for improving the affinity of cellulosic fabrics for disperse dyestuffs, the process comprising:
- (a) treating the fabric with an aqueous formulation of highly methylated melamine formaldehyde crosslinking agent, para-toluene sulfonic acid catalyst, isopropanol, and cationically emulsified low density polyethylene fabric softener;
- (b) drying the fabric;
- and then
- (c) heat transfer printing the fabric with a transfer printing paper containing disperse dyestuff.
A process for improving the affinity of cellulosic fabrics for disperse dyestuffs, the process comprising:
- (a) treating the fabric with an aqueous formulation of highly methylated melamine formaldehyde crosslinking agent, sulfonic acid salt catalyst selected from the group consisting of the ammonium and magnesium salts of said acid, isopropanol, and cationically emulsified low density polyethylene,
- (b) drying the fabric;
- and then
- (c) heat transfer printing the fabric with a transfer printing paper containing disperse dyestuff.
