FIELD: paper-and-pulp industry.
SUBSTANCE: invention relates to unbleached pulps, which are used in binder-based cellulose products, which are kraft pulp products. Cellulose product is maintained under alkali conditions during washing operation since initial soaking phase to cellulose drying step and exhibits chemical oxygen demand not higher than 2.0 kg per 1000 kg dry cellulose.
EFFECT: increased strength characteristics of product.
