FIELD: soft wares, paper.
SUBSTANCE: pulp, paper and method of its receiving concern rodophyte alga and can be used for pulp and paper industry. Rodophyte alga is dipped into extractive solvent, which allows solving of agar gel during target time. In the capacity of extractive solvent water, spirit or ketones are used. Soluted agar gel is subjected to interreaction with reacting solvent for its transformation into fiber. In the capacity of reacting solvent there spirits or ketones are used on the assumption on the condition that it differs from extractive solvent. Then received fiber is conditioned with condition agent usage. In the capacity of last mentioned aldehyde or oxalic aldehyde is used. Conditioned fiber is subjected to boiling.
EFFECT: providing of process efficiency and preventing of environmental pollution.
