Abstract

Способ получения углеродных волокон из целлюлозных волокон, отличающийся тем, что целлюлозные волокна, которые имеют содержание воды более 20 мас.ч. воды на 100 мас.ч. целлюлозных волокон, соединяют с раствором добавок, и затем целлюлозные волокна с добавками, которые содержат по меньшей мере 1 мас.ч. добавок на 100 мас.ч. целлюлозы, превращают в углеродные волокна.The method of obtaining carbon fibers from cellulosic fibers, characterized in that the cellulose fibers, which have a water content of more than 20 wt.h. water per 100 wt.h. cellulose fibers, combine with a solution of additives, and then cellulose fibers with additives, which contain at least 1 wt.h. additives per 100 wt.h. cellulose, converted into carbon fiber.
