Abstract: The hardwood fibers differ from softwood fibers chemically and morphologically in many respects. The short fibered pulps result in poor drainage, lower wet web strength and tendency of picking at press rolls. To combat these problems, besides other remedial measures, blending of long fibered pulps with short fibered pulps is one of the important aspect. Blending can be done in three distinct ways, e. g. chips blending, pulp blending before beating and pulp blending after beating. The physical strength properties in case of chips blending are severely affected due to different chemical compositions of raw materials requiring different dose of chemicals and processing conditions. The pulp blending before beating improves physical strength properties marginally, because morphological behaviour of different fibers and their response towards refining are different. The pulp blending after separate beating showed excellent physical strength properties In present investigation, the blending of chips/pulps of Ipomea carnea with chips/pulps of Cannabis sativa, Cannabis sativa hemp ribbon, and bamboo (Dendrocalamus strictus) has been studies.
