Abstract
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 120 g/m2 hand sheets were prepared for testing. Blending ratios were kept at 5, 10, 15 and 20% for both long fibre pulps.
Upon mixing 5, 10, 15, 20% Pinus eldarica pulp with hardwood pulp, breaking length increased to 6.9, 7.77, 8.01 and 9.14 Km. Respectively, and corresponding figures for imported pulp addition were 6.71, 8.2, 8.25 and 9.27 Km respectively. Tear index is also measured. Adding 5, 10, 15, 20% Pinus eldarica pulp to local hardwood pulp produced tear indexes of 5.93, 6.95, 6.65, 7.08 mNm2/g respectively and corresponding figures for imported pulp 5.38, 5.61 and 5.60 kPa. m2/g with blending above percentages of P. eldarica pulp and 4.78, 5.27, 5.38 and 6.23 kPa. m²/g upon addition of imported pulp.
