dc.description.abstractDelignification of bamboo (Phyllostachys bambusoides) grown in the Eastern Black Sea region of Turkey was carried out by kraft, kraft-anthraquinone (AQ) and kraft-sodium borohydride (NaBH4) pulping under a variety of conditions to determine the effect of AQ, NaBH4 and cooking parameters on pulp and paper properties such as yield, kappa number, viscosity, and strength properties. The chemical composition and fibre dimensions of the cell wall of Phyllostachys bambusoides culm fibres were also investigated. The analysed data revealed the following optimum krafi pulping conditions: Active alkali, 16% (as Na2O); NaBH4, 0.3%; AQ, 0.1%; and cooking time, 90 min. The modified kraft method with 0.1% AQ was found to provide better pulp properties than those with 0.3% NaBH4. Increasing the thickness of chip used in cooking from 2.0 mm to 4.0 mm increase the yield. The optimum cooking conditions of Phyllostachys bambusoides modified krafi pulps were found to be: screened yield, 48.1%; reject ratio, 0.53%; kappa number; 24.1; viscosity, 1210 ml/g; breaking length, 6.05 kin; burst index, 5.08 kPa m(2)/g; tearing index, 4.99 mNm(2)/g; brightness 20.35%.en_US
