FIELD: process engineering.
SUBSTANCE: invention relates to production of microfibrillar cellulose. Proposed process comprises preliminary processing of fibre accompanied with processing of said fibre with enzyme. Then, fibre is mixed with solution bearing alkaline metal hydroxide. Now, fibre is subjected to mechanical processing to produce microfibrillar cellulose. EFFECT: perfected process, lower energy costs.
EFFECT: 12 cl, 1 ex.
