Effects of Pulp Blending on Strength Properties of Ipomoea carnea Jacq

Abstract

Blending of long fibered pulps with short fibred pulp is one of the important aspects in paper making. The morphological and chemical nature of hard wood and soft wood fibers are different in many respects. Soft wood fibers have poor drainage, lower wet strength and at press rolls tendency of sticking. In order to overcome the problems and improve the quality, blending plays an important role. Pulp blending can be done in 3 distinct ways e.g., chips blending, pulp blending before beating and pulp blending after beating. Before pulp beating improves the physical strength marginally, but pulp blending after separate beating showed excellent physical strength properties. In the present investigation blending of pulp of Ipomoea carnea with pulps of bamboo has been studied.
