The effect of whole tree chips in pulp and papermaking
For a variety of reasons, the need for increased utilization of the world's pulpwood resource has become an important subject of discussion in the 1970's. Whole tree chipping, or the use of all above-ground portions of trees, is a feasible method of achieving this goal. Many reports have been …

Analysis of intra-increment pulping and papermaking properties of loblolly pine wood
… in that zone. Responses to refining and papermaking properties were investigated from the partitioned growth zones. For the four digestion series, fraction 2 refined the slowest followed by fractions 1 and 3 and then fractions 4 and 5. Differences in refining characteristics were defined …

Increasing Sustainability of the Papermaking Process via Formulation of Cellulose Nanofibers and Polyelectrolyte Complexes
… cellulose nanofibrils (CNFs) as additives in papermaking to improve properties and potentially replace plastics for multi-layer packaging applications. The trade-off, however, is that their micron and nanosized features require even greater amounts of energy to produce and to dry compared to …

A Chemical Comparison of Two Different Oxidizing Bleaches and the History of Early European Paper and Papermaking
Background: The bleaching of paper is an important and controversial treatment employed in the conservation of art. The use of a bleach may greatly enhance the quality of an image but at a cost of lost structural integrity. In order to fully consider the ramifications of bleaching a paper artifact, …

Model based cross-directional monitoring and control of plastic film thickness
… As with other sheet-forming processes, such as papermaking and steel rolling, the plastic film manufacturing process employs large arrays of actuators spread across a continuously moving sheet to control the cross-directional profiles of key product properties. In plastic manufacturing, the main …

GESTURES TOWARDS EMPTINESS: AN EXPLORATION OF RITUAL WITH REFERENCE TO BUDDHIST TRADITION AND INNOVATION
… variety of techniques and media: ashes on paper; papermaking; wood pulp; and watercolour. The written thesis entails an analysis of process and outcome in each series of works, seen in relationship to Buddhist and educational disciplines. A four-year period of pedagogical developments in small and …

TURBULENCE IN INDUSTRIAL POPULATIONS: THE CASE OF THE ITALIAN GRAPHIC PAPER INDUSTRY
… means of a new database for the Italian graphic papermaking industry between 1964 and 2004, this research inquires into the extent and character of entry and exit in an industry where innovation in products and processes has been incremental and largely predictable and, therefore, unlikely to be …

Investigation of organic composition of potential plants as alternative fiber in paper making industry
… From pulping process, the step will continue for papermaking. Lastly, tensile, bursting, folding, and tearing tester machine will test paper production. Result shows that pineapple leaf gives high cellulose content (66.2%) and lower lignin content (4.2%) compared corn stalk and napier grass. …

An analysis of the effectiveness of a behavioural based safety intervention in a UK paper mill
… observation programmes are not suitable for the papermaking industry, particularly when staffing levels are low due to challenging economic conditions. Observers are not available when there are high hazard situations and this suggests that BBS implementation is not the correct intervention for …
