Abstract

1. Способ получения волокнистого полуфабриката, заключающийся в нагреве измельченного целлюлозосодержащего сырья паром до температуры 195 - 240С при возрастающем давлении в процессе нагрева с последующим сбросом его до атмосферного, отличающийся тем, что при нагреве до 130 - 150С и давлении, равном 5 - 6 атм, сырье выдерживают в течение 30 - 300 с.2. Способ по п.1, отличающийся тем, что в процессе нагрева давление увеличивается до 35 - 40 атм.3. Способ по п. 1, отличающийся тем, что перед сбросом давления сырье выдерживают в течение 60 - 120 с.1. A method of obtaining a fibrous semi-finished product, which consists in heating the crushed cellulose-containing raw material with steam to a temperature of 195-240C with increasing pressure during heating, followed by its release to atmospheric, characterized in that when heated to 130-150C and a pressure of 5-6 atm , the raw material is kept for 30 - 300 s. 2. The method according to claim 1, characterized in that during heating, the pressure increases to 35-40 atm. 3. The method according to claim 1, characterized in that before releasing the pressure, the raw material is kept for 60 - 120 s.
