Abstract

PURPOSE: To obtain a captioned sponge-like molded body, excellent in water absorbing characteristic, easily collapsed by throwing into hot water and suitable for stopping bleeding, absorbing blood upon menses and the like, by manufacturing from specified materials and with a specified manufacturing method.
CONSTITUTION: Non-ionic cellulose ether B having low degree of substitution (low substituted substances of methyl cellulose, hydroxy methyl cellulose, hydroxy propyl methyl cellulose or the like and not soluble but inflatable by water) is dispersed uniformly (B is 5W200wt% of A) in solution (density of 1W20%) of polyvinyl alcohol A (average degree of polymerization is not less than 300, average degree of saponification is not less than 97%) and the viscous dispersed liquid, thus obtained, is agitated mechanically, then is foamed, thereafter, 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.
