(DMDHEU) is the most widely used crosslinking agent because it provides good durable press properties at low cost and is less detrimental to fabric strength, discoloration, and other properties than other agents. The finishing treatment comprises simply impregnating the cellulosic fabric with the pre-condensate so that it penetrates
into the fibers and then heating fabric to temperatures between 130-180C in the presence of a catalyst, so that the precondensate is converted into an insoluble resin by polycondensation in and around the fibers and/or by reacting
with the cellulose to form crosslinks
