Abstract

PURPOSE: To obtain a product, having a big water absorbing capacity and never collapsed until a condition of a specified water absorbing ratio while collapsed quickly when it is thrown into a big amount of water and agitated slowly, by manufacturing from specified materials and with a specified manufacturing method.
CONSTITUTION: Non-ionic cellulose ether B having low degree of substitution (a low substituted substance of cellulose same as a derivative A, and not soluble but inflatable by water) is dispersed (B is 5W200wt% of A) uniformly in solution (density of 1W20%) of soluble cellulose derivative A (one of methyl cellulose, hydroxy ethyl methyl cellulose, hydroxy propyl methyl cellulose or the like, and having a degree of polymerization wherein viscosity of 2% solution at 20°C becomes 2 centi-pois or more), then, viscous dispersed liquid, thus obtained, is agitated mechanically and foamed, thereafter, is thrown into a mold and is dried by refrigeration under reduced pressure. Thereby, a sponge-like molded body having an apparent specific gravity of about 0.01W0.3 may be obtained.
