SUBJECT of the Invention Provision of the manufacturing method of the cellulose fiber composition whose crystallinity degree is high at nanosize and which has little damage to fiber shape by the energy saving method which does not require a forceful physical grinding|pulverization， and a chemical-modification cellulose fiber composition. PROBLEM to be solved The following processes: The 1st means for supplying the contents， A 2nd means to have a rotation element which can produce a shear force and a protrusion pressure from this 1st means to the contents， And process of preparing the apparatus which comprises at least a 3rd means by which the contents from this 2nd means can be returned to this 1st means; Process of throwing a cellulose containing pulp and a disentanglement solvent into this 1st means; And disentanglement process of rotating the rotation element of this 2nd means with the circumferential speed of 20 m/s - 80 m/s， disentangling with a shear force， and forming the cellulose fiber of 2 nm - 800 nm of average fiber diameters; The manufacturing method of the cellulose fiber composition containing these and/or a chemical-modification cellulose fiber composition.
