| titleOfInvention | Manufacturing method porous paper filter and porous paper filter manufactured by the method |
| abstract | The present invention relates to a method for producing a porous paper filter which is easy to remove dust using freezing and drying by replacing water contained in cellulose with alcohols which are more nonpolar than water or by making cellulose fibers undifferentiate using an oxidizing agent or an enzymatic agent, To a porous paper filter manufactured thereby. According to the present invention, there is provided a method for producing a microfibrillated cellulose fiber, comprising: preparing a microfibrillated cellulose fiber; Preparing a cellulosic fiber suspension in which the undifferentiated cellulosic fibers are put in water to provide a cellulosic fiber suspension; Preparing a thin-film cellulose fiber by providing a thin-film cellulose fiber by filtering the cellulosic fiber suspension; And a freeze-drying step of freeze-drying the thin-film cellulose fibers. |
