ABSTRACT:
Superabsorbent articles in the form of soft, nonwoven fibrous webs are produced from aqueous fiber-forming polymer solutions by forming the polymer into water soluble filaments, contacting the filaments with a primary air stream having a velocity effective to attenuate and to partially dry the filaments, contacting the attenuated filaments with a secondary air stream having a velocity effective to fragment the filaments into fibers and to transport the fibers to a web-forming zone while also further attenuating and drying the fibers, collecting the fibers in reticulated web-form in the web-forming zone and curing the web to a water insoluble state. 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 such that the fibers are collected without sticking. Collection is preferably on a wire belt followed by transport through a curing oven to compacting rolls and web take-up.
