| titleOfInvention | Process for making solutions of cellulosic compounds |
| abstract | A solution of cellulose or cellulose derivative suitable for spinning, extruding or other shaping process is prepared by steeping unaged cellulose or a cellulosic derivative a plurality of times, consecutively, subsequently shredding and then aging prior to xanthation or the like. The concentration of alkali metal hydroxide of the solution used for resteeping is lower than that in the first steeping step. The process produces a viscose with less carbon disulfide than the conventional process without reduction in yield of cellulose. The process is adaptable for steeping in conventional press steeping apparatus or slurry steeping apparatus. |
