<p>PURPOSE: To obtain a superabsorbent nonwoven fibrous article by forming a polymer solution into water soluble filaments, web forming in a specific condition, and curing into a water insoluble web. CONSTITUTION: This article is obtained by extruding a polymer solution from an extruding machine 18 to form the water soluble filaments, partially attenuating and drying the filaments by the primary air stream generally guided in vertical direction. The attenuated filaments are fragmented with the secondary air stream from nozzle 22, dried, and the fragments 32 of the filaments are stuck on the screen 36. Curing in the curing oven 38, dens packing by nip rolls 58, 60, and winding up to the take up station 62 are successively performed. The temperature and air stream velocities are controlled with respect to ambient humidity and water content of the fiber during the fiber and web formation, so that the fibers are collected without sticking, and cured into a soft web.</p> |
