Natural fiber is a renewable resource characterized by its low cost and environmental friendliness. However, flame retardant properties are one of the biggest limitations for the preparation of composite materials that need to be improved. In this work, a novel complex flame retardant consisting of aluminum hydroxide (ALH) and decabromine diphenyl oxide (PBDE) was proposed to inhibit the therma...

As part of a program to reduce electrical energy consumption in the refining process, the effects of the ozone and alkaline peroxide treatments on fibre and handsheet properties, prior and subsequent to low consistency (LC) refining, were assessed and compared by applying different levels of ozone and a range of peroxide and alkali charges to a primary stage hemlock thermomechanical pulp (TMP)....

Paper furnishes often contain a mixture of a weak pulp with relatively short fibers and a strong pulp with relatively long fibers. Whereas increased proportion of the long-fiber pulp can be expected to impair formation, it has been unclear to what extent a change in formation through the pulp ratio affects the strength efficiency. (Strength efficiency is a measure of how well the strength poten...

The adsorption of cellulases onto fibers may be one of the most important factors affecting the enzymatic reaction between cellulases and fibers. This study investigated the adsorption kinetics involved, using isothermal adsorption equations. Cellulose binding domains (CBDs) were isolated from a commercial cellulase, and their role in the adsorption and enzymatic reaction was evaluated. Approxi...

This research relates to the cellulosic fibres of treated deinked Mixed Office Waste (MOW) paper and is directed particularity to a method for improving the wet strength of recycled paper. The effect of chemical treatment of fibre was investigated. Fibres were treated with 6 and 10% Succinic Acid (SA), with 3% and 5% catalysts (based on the total weight of fibres). The catalysts used for this r...

Beating is one of the most important and complicated processes that influences paper production quality from both a process property standpoint.
 With increasing costs, environmental regulations competitiveness in today’s global market, board producers revisit existing to decrease costs. New approached with additives such as new developed in-situ precipitated fillers materials have potenti...

he bast fiber of Mitsumata （Edgeworthia papyrifera Sieb. et Zucc.） has traditionally been used as a raw material paper. belongs to Thymelaeaceae family, and the paper made from its bark is known have hue egg yolk color unique texture. pulp for making manufactured follows. branches are steamed barks taken off, which epidermis cuticle removed. Then, residual white cooked with an aqueous alkaline ...

soda and soda-aq pulping of corn stalk applying different charges of active alkali and pulping time was studied. the average value of fiber length, diameter and cell wall thickness were measured as 1.03 mm, 23.64 µm and 5.26 µm, respectively. the content of alcohol-acetone extractives, cellulose, lignin, extractives soluble in 1% naoh and ash content of corn stalk were determined as 15%, 51.2%,...
