Amic acids and half salts derived from 1,2,- or 1,3-dicarboxylic acids were used with methylol reagents as coreactant curing catalysts to produce durable-press cotton fabrics by a pad-cure process. Maleamic acid (derived from malcic anhydride and ammonia) and the monosodium, ammonium, and potassium salts of maleic acid, when used with DMDIIEU, generated the highest levels of wrinkle recovery. The formation of permanent creases in these fully cured fabrics, which also had a strong affinity for basic dyes, is discussed.
