Wool fabric was crosslinked using dimethylolethyleneurea (DMEU) and melamine resins with acidic salt catalysts. Water, alcohol and formic acid were used as pad bath solvents. As the ability of the solvent to swell wool fibers increased, the locus of reaction tended to be more nearly within the fiber than on the surface. Polymerization on the surface led to a reduction of felting shrinkage and a stiffening of the fabric. Internally deposited resins contributed less to shrink resistance but gave fabrics with good hand and evidence of improved wrinkle recovery. Evidence is presented that the treatments crosslinked the fabric but Mused little change in tensile properties. [ABSTRACT FROM AUTHOR]
