Conclusions
The hemicellulose content of the squeezed-out alkali and of the working alkali depends only on the hemicellulose content of the starting cellulose, on the α-cellulose content of the alkali cellulose, and on the amount of the squeezed-out alkali which is drawn off from the mercerization cycle.
The total hemicellulose content of the alkali cellulose in mercerization in bulk does not depend on the α-cellulose content of the alkali cellulose.
The use of an alkali cellulose containing 23–24% α-cellulose will make it possible to reduce the hemicellulose content of the working and squeezed-out alkali by 16–18 g/liter.
