Rapeseed Straw as a Possible Source for the Production of Fibre Materials
Original language description
Rapeseed straw was tested as a non-wood raw material for the production of cellulosic pulps. To characterize chemical composition of rapeseed straw, holocellulose, lignin, ash, and extractives were determined. Preliminary soda pulping experiments showedsuitable cooking conditions, viz. an active alkali charge of 17 %, a liquor-to-raw material ratio of 5:1, a cooking temperature of 160 ?C, and an H-factor of 1 600 h were sufficient to produce pulp with a low content of rejects. Under these conditions, apercentage total pulp yield of 37.1 %, a kappa number of 38.3, and an amount of rejects of 1.1 % were achieved. For selected samples of pulp, the bonding and strength properties of pulp fibres exhibiting good beatability were evaluated by a simple rheosedimentation method and by measuring tensile strength.
