FIELD: wood-pulp and paper industry. ^ SUBSTANCE: fibrous material is subject to compression. Pectin-enriched areas in walls of fiber are attenuated selectively due to impregnation of fibrous material with water-based pectines-containing liquid, which results in hydrolysis of pectines. Fibrous material is divided to fibers and refined to produce wood fibrous pulp. ^ EFFECT: limitation of losses of outcome of fibrous pulp to level at which level decomposition of pectines occurs. ^ 22 cl, 3 dwg, 4 tbl, 4 ex |
