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
## Synopsis Fourier transform infrared (FTIR) spectroscopy has been used as a modern analytical tool to elucidate the structure of urea-formaldehyde (UF) resins. Several low molecular weight condensation products of urea and formaldehyde were synthesized and characterized. Structural differences w
