Investigation on potential long fibre Pinus eldarica Kraft Pulp

Kraft pulping of Pinus eldarica wood was carried out at 18% active alkali, 25% sulphidity and pulping temperature & Time of 165 C and 90 minutes pulp was compared with imported unbleached long fibre pulp with the kappa number of 34. Pinus eldarica pulp (500 ml csf) and imported long fibre pulp 1...
