Abstract:
In this paper, characteristics and chemical composition of bamboo (phyllo-stachys pubescens) fibre are studied. With alkaline sodium sulfite-anthraquinone (ASP-AQ) pulping process, pulping characteristics of the bamboo fibre as well as its pulp physical strength are investigated. Results of tests indicate that opti mum ratio of sodium sulfite to total alkali (calculated as sodium oxide) is 0.85, the total amount of alkali is 18% (calculated as sodium oxide) and that of anthraquinone 0.05%. For the ratio of liquid to bamboo chips at 4:1, pulping time 3.5 of hours at the maximum temperature 170℃ is required. The total pulp yield thus obtained is 42~45%, 4~6% higher than the yield of the conventional kraft pulp, the kappa mumber being 17~25. The strength properties of ASP-AQ bamboo pulp is similar to those of kraft bamboo pulp. Therefore, ASP-AQ pulping process should be regarded as a better method to produce chemical pulp.
