Abstract

Kanchong is promoted to plant for potential development as economical plant. It is one economical plant in Thailand according to various special properties and high quality fiber. Kanchong fiber is suitable for using as raw material for pulping according to having high alpha-cellulose. Study on Kraft pulping of Kanchong show that optimum condition for Kanchong wood are sulfidity 25%, active alkali 19%. cooking time 3 hours and maximum temperature 165°C which gives pulp yield 49.25% and kappa number 19.09; optimun condition for Kanchong whole stem are sulfidity 25%, active alkali 21%, cooking time 3 hours and maximum temperature 165°C, which gives pulp yield 49.21% and kappa number 18.89. Quality of pulp produced is good and has high tensile strength. Pulp produced is suitable for single layered bag paper and wrapping paper.
