Abstract
Nowadays, it is necessary to develop new native resources of raw materials for producing consumer goods, in particular, pulp and paper, because of the increased demand for pulp for papermaking and the shortage of wood. In this study, rapeseed straw was studied in order to evaluate it as pulping raw material. Laboratory experiments were carried out to investigate the effect of cooking parameters on the properties of rape pulp. The obtained results indicate that the cooking conditions have an impact on pulp yield, residual lignin content and brightness. The fibre length distribution, as well as the physical properties of handmade paper sheets, was investigated. Comparing the results obtained, it can be concluded that the peracetic pulp obtained with sodium molybdate catalyst presents better results with regard to strength properties. The possibility of using organosolv rape pulp in the composition of printing paper was evaluated. In conclusion, rape straw can be recommended for peracetic pulp and paper production.
