Latest Patents
One of Kenji Oba's latest patents is titled "Absorbent and absorbent article provided therewith." This invention addresses the challenge of creating a novel absorbent that combines a water-absorbing cellulose-based fiber with a thermoplastic resin fiber. The thermoplastic resin fiber contains an unsaturated carboxylic acid or an unsaturated carboxylic acid anhydride as a monomer component. The invention ensures that the absorbent maintains both sufficient strength and absorption properties. The mass ratio of the water-absorbing cellulose-based fiber to the thermoplastic resin fiber is controlled between 90:10 to 50:50, with a density ranging from 0.06 to 0.14 g/cm.
Another significant patent is the "Method for making package-absorbent article assembly and package-absorbent article assembly obtained by the same." This method outlines a systematic approach to packaging absorbent article assemblies. It involves feeding first and second breast milk absorbent pads onto a wrapping sheet web, displacing them from a transverse center line, and folding the pads back to create a joint zone. This innovative packaging method enhances the efficiency and effectiveness of absorbent product assembly.
