eng	Oxidized cellulose with different carboxyl content: Structure and properties before and after beating	Beating and refining or mechanical treatment of fibers in water is an important step in using pulps for papermaking. It is an energy intensive process. During beating of samples about different ratio of oxidation it was found, that samples with higher contents of COOH groups in starting pulp are characterized by a significantly lower specific beating energy consumption needed to achieving the same sizes of particles. X-ray analyse shows that for non-beated oxidized cellulose was perceptible high share amorphous contents compared with beated oxidized cellulose.	oxycellulose; amorphous and crystalline regions; beating, X-ray diffraction; degree of polymerization
