Kraft pulping characteristics and pulp properties of warm season grasses

Bioresource Technology, 1999
Abstract Non-wood fibres are increasingly being used in the pulp and paper industry to help meet the increasing world demand for paper. Their use also helps to reduce demand on declining forest reserves. In this study several warm season grasses, prairie sandreed (Calmovilfa longifolia (Hook.) Scribn.), cordgrass (Spartina pectinata L.), big bluestem

Improvement of bleached wheat straw pulp properties by using aspen high-yield pulp

Bioresource Technology, 2012
The bleached wheat straw pulp (BWSP) accounts for about 25% of the virgin fiber supply in the Chinese Pulp and Paper Industry. As a non-wood chemical pulp, BWSP is known to have low bulk, low light scattering coefficient and poor drainage due to its high content of parenchyma cells.

Mechanical Properties of Molded Pulp Pallet

Applied Mechanics and Materials, 2011
Molded pulp material has been paid much attention for the cushioning package, yet there is no perfect method for evaluate the cushioning properties of different molded pulp configurations, which hampers the advance of molded pulp industry. In this paper an Equivalent Area Theory are put forward in order to study the cushioning properties of this ...

Some electrical properties of wood pulp

Journal of Polymer Science: Polymer Chemistry Edition, 1978
AbstractThe variation with temperature and frequency of the dielectric constant ε′ and the dielectric loss ε″ for sheet wood pulp and ground wood pulp were measured. Also, the effect of the relative humidity on the dielectric behavior was measured for the ground sample at 25°C.

Mechanical properties of paper-pulp packaging

Composites Science and Technology, 2003
Promoting the application of environmentally friendly packaging such as those made out of paper-pulp requires a basic understanding of the mechanical behaviour of paper-pulp (material) as well as that of packaging (product). In this paper, results from the investigation to determine the mechanical properties of paper-pulp packaging are presented.

Rheological Properties of Fresh Jujube Pulp

Advanced Materials Research, 2013
The rheological behavior of fresh jujube pulp with different concentration (30%-50%) was studied at a wide range of temperature (20°C-60°C) and homogenization pressure (0M-25MPa)in this paper. The result shown particle of fresh jujube pulp decreases with homogenization pressure, viscosity increased with concentration increase but decreases with ...

Viscoelastic Properties of Dental Pulp Tissue and Ramifications on Biomaterial Development for Pulp Regeneration

Journal of Endodontics, 2015
A critical step in biomaterial selection effort is the determination of material as well as the biological properties of the target tissue. Previously, the selection of biomaterials and carriers for dental pulp regeneration has been solely based on empirical experience.In this study, first, the linear viscoelastic material functions and compressive ...

Properties and treatments of pulps from recycled paper. Part I. Physical and chemical properties of pulps

Cellulose, 1999
The mechanical, physical, and chemical properties of recycled pulps were evaluated after a series of treatments designed to improve and/or modify the pulp characteristics. Tensile strength, bursting strength, and apparent density of the pulps decreased with recycling. However, the tear strength, in most cases, increased after the first recycle and then

Pulp Properties and Their Influence on Enzymatic Degradability

Biomacromolecules, 2012
Endoglucanase treatment of pulp for the adjustment of viscosity and the increase in pulp reactivity is a promising step in the concept for the beneficial production of dissolving pulps from paper grade pulps. To promote the commercial applicability of these enzymes, the influence of pulp properties such as carbohydrate composition, pulp type and ...
