A planting program, in which the yield and physico-chemical properties of wood are considered can enhance the utilization of Poplar trees as one of main feedstock for pulping plants and particle. The papermaking properties are prospect of the chemical and morphological properties of this non-wood material. It has a higher slender ratio which facilitates the production of pulp with better tear strength than other similar fibre length material. It has similar papermaking properties to hardwood.
These species were characterized with high lignin content and low α-cellulose content. The pulping of these six mangrove species was also carried out by kraft process and papermaking properties were also evaluated. Pulp yield was lower and kappa number was higher as compared with other tropical hardwoods. Properties of non-wood plants as raw material for paper .. 15 Fibre morphology in non-wood plants used in papermaking .. 15 Chemical composition.. 18 Possibilities for improving biomass yield and quality by crop Strategy used for selecting species for non-wood pulping .. 78 The preconditions for.
Designed to serve as a new educational tool for pulp and paper science courses and as an extensive resource for industry professionals. Rather than focus on the many types of equipment in use, this book emphasizes the principles of pulp and paper processes. Pulp made from pine species is usually produced using a sulphate method, while spruce is used as a raw material in the production of mechanical pulps.

The book offers a concise yet thorough introduction to the process of papermaking from the production of wood chips to the final testing and use of the paper product.
The author has updated the extensive bibliography, providing the Pulping and paper making properties of fast-growingplantation wood species book with easy access to the pulp and paper literature.
The weight loss was only 6%, but a decrease in optical properties had to be accepted. After sulfite cooking of wood chips pretreated for 2 weeks, the Kappa number decreased by 30% with hard- and softwood. Tensile and tear indices decreased by only 10%, while the brightness of unbleached pulp increased by 4% with birch.
In general, the main raw materials of pulp and papermaking industry can be classified into three categories: wood, non-wood, and non-plant (mainly wastepaper), of which non-wood fiber material is an important fiber source in the areas where forest resources are scarce. Nowadays, in the total pulp consumption of the world, the proportions of wood pulp, wastepaper pulp, and non-wood pulp are.

Properties of Selected Wood Species. Alongside the traditional aspects of pulping and papermaking processes, this book also focuses on biotechnological methods, which is the distinguishing feature of this book.
It includes wood-based products and chemicals, production of dissolving pulp, hexenuronic acid removal, alternative chemical recovery processes, forest products biorefinery. Background: There is a global need to search for new types of fibers’s wood to assess its suitability for the paper production as a result of the population increase in the ive: Therefore, this trial was conducted to evaluate paper pulp produced and determination of the papermaking characteristics from woods of Populus alba, Eucalyptus camaldulensis, Acacia nilotica as hardwoods.
In its Second Edition, Handbook of Pulping and Papermaking is a comprehensive reference for industry and academia. The book offers a concise yet thorough introduction to the process of papermaking from the production of wood chips to the final testing and use of the paper product.

other wood unit required per ton of pulp. In addition to the factors discussed above, these measures are affected by wood density. Yield is generally higher (less wood is required) for denser species.
To estimate wood required per ton of pulp, the following information is needed: (1) moisture content of pulp, (2) pulp yield, and (3) specific.Papermaking - Papermaking - Processes for preparing pulp: Mechanical or groundwood pulp is made by subjecting wood to an abrading action, either by pressing the wood against a revolving grinding stone or by passing chips through a mill.
The wood fibres are separated and, to a considerable degree, fragmented. Chemical wood pulp is made by cooking wood chips with chemical solutions in digesters.chemical pulp produced in the United States. The choice of pulping process is determined by the desired product, by the wood species available, and by economic considerations.
