Latest Patents

Kawagoe's latest patents include a semipermeable membrane and a method of manufacturing the same. This invention aims to provide a semipermeable membrane that maintains substance permeability over time. The membrane contains a resin and achieves a permeation rate of albumin of no lower than 30%. Additionally, the albumin adsorption amount is limited to no greater than 10 µg/cm when immersed in a 0.1% albumin solution for 90 minutes. The water permeation amount is expressed as no smaller than 1,000 L/(mhour) when subjected to a negative pressure of 3±0.2 kPa. This semipermeable membrane is designed to isolate cells from their external environment.

Another notable patent is for a paper composite, which consists of a paper substrate with an air permeation resistance of 1,000 seconds or less and a bulk density ranging from 0.5 to 1.0 g/cm. This composite features a greaseproof layer on at least one side, containing an ethylene-vinyl alcohol polymer and a cationic fluorine-containing polymer. The composition of the greaseproof layer is carefully balanced to ensure optimal performance, with a water vapor permeability of 1,000 g/m·24 h or greater.
