Abstract
In order to investigate the influence of fine structure on the alkali solubility curve of pulp, the hydrolized residues (crystalline region and crystalline region containning mesomorphous region) were prepared from linter pulp, rayon wood pulp and bleached sulfite paper pulp, by dilute acid hydrolysis for 30 minutes and 3 hours respectively, and their alkali solubilities were determined.
The degraded cellulose samples were prepared from linter pulp and rayon pulp by irradiation of ultra violet rays, and their alkali solubilities were also determined.
From the results obtained the influence of fine structure and degree of polymerization of pulp on the alkali solubility curve of pulp are discussed.
