Good smooth–drying properties are imparted to cotton by treatment with divinyl ethers in dimethylformamide in the presence of catalytic quantities of concentrated hydrochloric acid. The acetal cross–links responsible are stable to alkaline laundering, and this type of finish does not retain chlorine. Better crease recovery–strength relationships can be achieved in this way than by the use of dimethylolcyclicethyleneurea, the greatest improvement in crease recovery occurring at a degree of substitution which corresponds to 0–05 cross–links per anhydroglucose unit. Values of Smooth–drying Index correlate well with crease–recovery angles, whereas Monsanto Grades do not.
