摘要： The invention concerns a membrane filtration type hollow fiber. It is composed of a single material phase which material is a chain high polymer such as cellulose acetate and capable of forming fibers by the spinning of the high polymer. The cylindrical wall defining the hollow fiber represents a three-dimensional net-like structure of fine filtering passages. This structure occupies substantially the whole mass of the tubular wall or a closed ring band zone when seen in any cross-section of the wall, providing thus an effective and active filtering zone. The pore rate amounts to at least 55%, and active points of the filtering passages for governing minimum passable sizes of the passages for solids included in a filtering liquor to be treated upon are distributed at random throughout at least the active zone. These sizes are nearly uniform.

摘要： The invention concerns a membrane filtration type hollow fiber. It is composed of a single material phase which material is a chain high polymer and capable of forming fibers by the spinning of the high polymer. The cylindrical wall defining the hollow fiber represents a three-dimensional net-like structure of fine filtering passages of 0.05 to 1 micron, preferably 0.1 to 1 micron. This structure occupies substantially the whole mass of the tubular wall or a closed ring band zone when seen in any cross-section of the wall, providing thus an effective and active filtering zone. The pore rate amounts to at least 55%, and active points of the filtering passages for governing minimum passable sizes of the passages for solids included in a filtering liquor to be treated upon are distributed at random throughout at least the active zone. These sizes are nearly uniform.

摘要： A cellulose microcapsule having absorbing capacity, consisting of outer semipermeable barrier layer of cellulose and absorbent powders dispersed within inner cellulose gel matrix is prepared by dispersing adsorbent powders in a solution of cellulose dissolved in a solvent which is not adversely affected by the adsorbing capacity of adsorbent powders and capable of dissolving cellulose, then forming the dispersion into droplets and finally precipitating cellulose on the droplets. It is excellent in resistance to chemicals such as acids, alkalis or organic solvents and is useful for various purposes.
