Abstract
INVESTIGATIONS1 on the hydrolysis and water-regaining properties of wood pulp, cotton and cotton linters swelled in sodium hydroxide solutions of varying concentrations showed that, whereas for wood pulps a low constant-limit degree of polymerization and high constant water-regain were reached by swelling in an 8 per cent lye, it was necessary to swell cotton and cotton linters in a 10 per cent solution in order to obtain a similar result. These differences between swollen samples of the two fibres might be due to easier mercerizing, that is, transformation of the cellulose I lattice into the cellulose II lattice, in the case of the wood pulp as compared with the cotton linters.
