Abstract
(EN)
The present invention addresses the problem of providing a fibrous cellulose which has a phosphorus oxoacid group and which exhibits excellent heat resistance. The present invention relates to a fibrous cellulose containing a phosphoric acid group and a phosphorus acid group. In addition, the present invention relates to a method for producing a fibrous cellulose, the method including a step for mixing a cellulose raw material with a phosphoric acid group-containing compound and/or a salt thereof, a phosphorus acid group-containing compound and/or a salt thereof, and urea and/or a urea derivative so as to obtain a cellulose raw material having a phosphoric acid group and a phosphorus acid group.

L'invention a pour objet de fournir une cellulose sous forme de fibres qui possède un groupe oxo-acide phosphorique, et qui présente une excellente résistance à la chaleur. Plus précisément, l'invention concerne une cellulose sous forme de fibres qui contient un groupe acide phosphorique et un groupe acide phosphoreux. En outre, l'invention concerne un procédé de fabrication de cellulose sous forme de fibres qui inclut une étape au cours de laquelle un composé possédant un groupe acide phosphorique et/ou un sel de celui-ci, un composé possédant un groupe acide phosphoreux et/ou un sel de celui-ci, et une urée et/ou un dérivé d'urée, sont mélangés, et une matière de départ de cellulose possédant un groupe acide phosphorique et un groupe acide phosphoreux, est obtenue.
