Abstract Xylan is the main contaminant of hardwood sulphite dissolving pulp used for production regenerated cellulose. The amount xylan in should not exceed minimum allowable values and which easy to achieve. To control pulping process, a basic knowledge removal essential. In this study, Eucalyptus globulus glucuronoxylan (GX) conversion during acidic Mg-base acid was assessed first time pilot ...

The behaviour of different cellulosic fibres during acid hydrolysis has been investigated and the levelling-off degree of polymerisation (LODP) has been determined. The study included a bleached kraft pulp (both never-dried and once-dried) and two dissolving pulps (once-dried). Additionally, cotton cellulose from new cotton sheets and sheets discarded after long-time use was studied. Experiment...
