FIELD: paper manufacture. SUBSTANCE: fibrous mass has magnesium-bisulfite and semicellulose from deciduous wood strains and indicated semicellulose at the yield 69-72% obtained at pH 5.3-5.8 at total SO2 content 3.0-3.4%. Fibrous semifinished product from coniferous wood strains - bisulfite cellulose at the yield 60-62% at the following ratio of components, wt.-%: magnesium-bisulfite cellulose from deciduous wood strains 85-90; magnesium-bisulfite cellulose from coniferous wood strains 10-15. Crimped paper obtained from proposed fibrous mass shows high resistance to planar compression at increased utilization of parental deciduous wood. EFFECT: enhanced quality of fibrous mass. 1 tbl
