METHOD OF PRODUCTION OF PULP Russian patent published in 2009 - IPC D21C5/00 D21C1/06 D21C9/12 D21B1/16 D01C1/02

Abstract RU 2343241 C1

FIELD: textiles; paper.

SUBSTANCE: method refers to production of pulp from flax raw material and can be used in the paper-pulp industry for producing of pulp for chemical processing as well as for example of cotton wool, paper and cardboad. The method is realised by means of consequent simultaneous tillage and purification of flax-cuke or flax straw, washing and cutting of the material. Then it is soaked, processed in a thermochemical way, washed through and bleached. Then it is washed again, wrung and dried. Following thermomechanic processing of the pulp containing material it is possible to perform maturation in the alkaline solution.

EFFECT: efficiency increase of method of producing of pulp from flax raw material with high degree of chaff.
