Abstract: Indian pulp and paper industries are facing an acute shortage of good quality of wood fibre with other associated problems. So they could not match their final product vis-a-vis to the finished products in globally competitive market. To overcome a serious lack of domestic wood fibres, morphological as well as chemical investigations on abundantly available and fast growing non-woody fibrous plants, which resemble in some aspects with softwoods and bamboo, have been undertaken. Keeping this challenge in view the pulp and paper making characteristics of three non-woody plants namely, Eulaliopsis binaia, Cajanus cajan, and Sesbania sesban have been studied extensively. Eulaliopsis binata, which is popularly known as ‘Sabai grass', consists of long leaf fibres. The fibre length of sabai grass is more than that of bamboo but fibre diam is 2.5-times lower than bamboo. Sabai grass consists of high cellulose and pectase with low lignin content. Sesbania sesban popularly known as 'Jainti' and consists of both bast and woody fibres. The rigidity coefficient, wall fraction and runkel ratio resembles that of bamboo, however the fibre length lies in the vicinity of fibre length of eucalyptus. Cajanus cajon shows higher degree of conformability within the sheet due to lower value of runkel ratio, slenderness ratio. wall fraction and rigidity coefficient and result in greater degree of fibre collapse and higher degree of conformability within the sheet.
