FIELD: chemistry.
SUBSTANCE: invention relates to the technology of making fire-resistant fibre, particularly to making silicate-containing fibre. The method of making such fibre involves mixing viscose with silicon dioxide and passing the mixture through bushing openings into a reducing solution. The reducing solution contains 40-150 g/l sulphuric acid, 20-40 wt % sodium sulphate, 0-100 g/l zinc sulphate and 50-1000 mg/l sodium silicate.
EFFECT: obtaining fire-resistant fibre.
