Evaluating the Performance of Hemp Bast Fibres in the Production of Packaging Paper using Different Wastepaper Blends DILEK YAYLALI 1 , CANAN URAZ 1 & ESAT GÜMÜŞKAYA 2 The predicted scarcity of wood-based fibre supplies has necessitated the search for alternative sources including non-woods by paper manufacturers. As a raw material for pulping, hemp bast fibre has some potential. To provide a guide for the pulp and paper industries, the suitability of hemp bast fibres for the pulp and paper industries was evaluated in this study, and blending trials with wastepaper pulp were conducted. In the hemp bast fibre preparation, the length of the fibres was first reduced to 4 mm. Subsequently, kraft pulping was applied to them. Along with the preparation of wastepaper pulps, hemp bast fibres and wastepaper handsheets were prepared according to a blending plan. Finally, the handsheets were subjected to paper strength tests. The properties of raw, cooked and beaten hemp bast fibres were investigated by characterisation methods such as optical microscopy, X-ray diffraction and Fourier-transform infrared spectroscopy. Additionally, carbohydrate components, solubility and ash content tests were run on raw hemp bast fibres. As a result of the experiments and analyses, the targeted results were achieved. Following the resolution of the fibrillation problem, it was determined that hemp bast fibre pulp can be used in adequate blends of wastepaper pulp when the strength values of the end product are desired to be increased (including CMT, CCT, RCT, SCT, stiffness and tear resistance) or decreased (air resistance). 1.

The Paper Industry Technical Association (PITA) is an independent organisation which operates for the general benefit of its members – both individual and corporate – dedicated to promoting and improving the technical and scientific knowledge of those working in the UK pulp and paper industry. Formed in 1960, it serves the Industry, both manufacturers and suppliers, by providing a forum for members to meet and network; it organises visits, conferences and training seminars that cover all aspects of papermaking science. It also publishes the prestigious journal Paper Technology International ® and the PITA Annual Review , both sent free to members, and a range of other technical publications which include conference proceedings and the acclaimed Essential Guide to Aqueous Coating .
