초록

For the development of economic, automated, and computer-aided manufacturing process of textile printing screen, photocuring of PVA emulsion by argon LASER was studied. The crosslinking-degree of PVA, photosensitized by diazonium salt, was analyzed by gravimetric and IR-spectroscopic method. The exposure time was longer than 4 $\mu$s with 1 W power and 50 $\mu$m spot size for processable crosslinking. The crosslinking behavior of PVA showed typical S-shape kinetics against the cumulative exposure time.
