Urea-glyoxal-formaldehyde cellulose reactant

Claim 1

A process for producing a curable low formaldehyde releasing finish on cellulosic textile materials comprising: applying an aqueous solution of water-soluble urea-formaldehyde-glyoxal condensation product, an accelerator and a surface active agent to a cellulosic textile, drying the treated textile, and pressing the dried textile at elevated temperature; said water-soluble urea-formaldehyde-glyoxal condensation product prepared by a process comprising reacting in an equeous medium about 1.0 mole of urea, about 1.0 mole of glyoxal and less then 2.0 moles of formaldehyde at a pH maintained betwee 6.2 and 6.7 and at a temperature of 40° C. until the formation of 1,3-demethylol-4,5-dihydroxy-2-imidazolidinone is essentially completed, adding an acidic material to the reaction solution to adjust the pH between 2.0 and 3.0, maintaining the pH between 2.0 and 3.0 and at a temperature between 40° and 90° C. for a period of at least 0.5 to 3.0 hours and adding a base to the solution to adjust the final pH of the solution between 5.0 and 7.0.
