FIELD: paper production; cellulose production.
SUBSTANCE: modified kraft pulp with unique properties is presented. In the method, the modified fibre may be a modified bleached kraft fiber that is almost indistinguishable from its conventional counterpart, except that it has a low degree of polymerization (DP). In addition, the methods for manufacturing such modified fibre and products made from it are provided. Method can be carried out in a single step of an acidic iron-catalyzed hydrogen peroxide treatment process, which can be included in a single step of a multi-stage bleaching process.
EFFECT: products can be chemical raw materials of cellulose, microcrystalline cellulose raw materials, fluff pulp and products made from them.
