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.

Creasable durable press textiles from methylol reagents and half amides

Acidic monomers are polymerized in aqueous solutions containing a free radical initiating catalyst and a methylol amide reagent or formaldehyde. The resulting acidic polymers have very high molecular weight as measured by the viscosities of dilute solutions of the acidic and neutralized polymers. The reaction solutions can be used to form tough, insoluble films, and the polymers can serve as effective thickening agents and floculating agents.
