METHOD OF PRODUCTION OF CELLULOSE Russian patent published in 2013 - IPC D21C1/06 D21C3/02 D21C9/00

Abstract RU 2487206 C1

FIELD: textiles, paper.

SUBSTANCE: method is carried out by successive soaking of cellulose raw material in alkaline solution thermo-mechanical chemical processing, extraction, washing, bleaching, extraction, washing, extraction and drying, and herbaceous plants are taken as the cellulose raw material. Before drying the cellulose raw material is loosened to individual fibres, transported on screws in which the diffusion alignment is carried out on moisture by volume, followed by drying in a microwave unit.

EFFECT: invention enables to reduce energy costs and to obtain cellulose which is uniform on quality characteristics.
