SURFACE TREATED MODIFIED CELLULOSE FROM CHEMICAL KRAFT FIBER AND METHODS OF MAKING AND USING THE SAME Russian patent published in 2018 - IPC A61L15/28 A61F13/15 D21C9/10 D21H11/16 B01J20/28

Abstract RU 2671504 C2

FIELD: medicine.

SUBSTANCE: group of inventions relates to medicine. Modified kraft pulp fiber, which has a low degree of polymerization (DP), is described. Method for manufacturing a modified fiber and products obtained therefrom is described. Process is a one-step, iron-catalyzed peroxide treatment in an acid medium, which can be incorporated into a single stage of a multi-stage bleaching process. Products are chemical cellulose starting materials, microcrystalline cellulosic starting materials, fluff pulp and products made from them.

EFFECT: fiber has improved chemical properties without physical destruction and discoloration.
