Abstract

Настоящее изобретение относится к способу производства непрерывной формовки (11) с использованием экструзионного раствора, содержащего преимущественно воду, целлюлозу и третичный аминоксид. Экструзионный раствор подвергается экструзии через отверстие (10) экструзионного канала, в результате чего получается непрерывная формовка. Непрерывная формовка проводится через воздушный промежуток (12). В настоящем изобретении с целью повышения способности не создавать петель и уменьшения тенденции к фибрилляции осуществляется управление средним ускорением и/или средней плотностью теплового потока в соответствии с определенными формулами.Международная заявка была опубликована вместе с отчетом о международном поиске.
