Effect of Stress Applied During Drying on Some Properties of Individual Pulp Fibers

Springwood and summerwood fibers of a longleaf pine holocellulose pulp were dried under various axial tensile loads. Elongation measurements during drying showed that the fibers underwent a sudden extension at the commencement of drying which was independent of the drying load. Drying of fibers under load caused an increase in Young’s modulus, tensile strength, work-to-rupture, and crystallite orientation; it caused a decrease in ultimate elongation, and the crystallinity remained the same. In general, the springwood fibers underwent much larger changes than did the summerwood.
