The preparation of fibers from aqueous urea-formaldehyde resins has been investigated; a dry spinning process has been developed based on the extrusion of catalyzed resin into a drying chamber at 180 -220°C, producing a multifilament yarn at spinning speeds of up to 600 m/min. A range of UF filament

The favored pH ranges for the formation of urons in urea-formaldehyde (UF) resins preparation were determined, these being at pH's higher than 6 and lower than 4 at which the equilibrium urons £ N,NЈ-dimethylol ureas are shifted in favor of the cyclic uron species. Shifting the pH slowly during the
