Abstract
Cellulosic textiles are impregnated with an aqueous solution containing a methylol crosslinking reagent and either a half amide of a 1,2- or 1,3-dicarboxylic acid or a half ammonium, sodium, or potassium salt of a 1,2- or 1,3-dicarboxylic acid. After the impregnated textiles are cured, they have high levels of crosslinking as indicated by high resilience and high levels of acidic groups as indicated by basic dye adsorption and the ability to form new, permanent creases when pressed at high temperatures.
