Manufacture of Low Density Paper by Cationic Fatty Acid Amine Bulky Promotor Treatment (3) - Effect of Pulp Beating Degree and Bulky Promotor Concentration -

Abstract

The effects of pulp beating degree and bulky promotor concentration on the properties of handsheet including a bulk and strength have been investigated during manufacturing of low density paper (high bulk paper) with cationic fatty acid bulky promotor. It was found that paper bulk increased with increasing cationic fatty acid bulky agent concentration, while tensile strength decreased. On the other hand the opacity of handseets also increased with increasing cationic fatty acid bulky agent concentration, while brightness decreased slightly. With increasing pulp beating degree, paper bulk as well as tensile strength increased, while opacity decreased. Brightness did not show a significant difference with increasing pulp beating degree. The highest bulk and strength values were observed when 1.5% (SwBKP) and 2% (HwBKP) of bulky promotor was treated into the 450 mL CSF pulp slurry.

Thermal and Chemical Characterization of Bleached Cellulose From Horse Grass (Andropogon Tectorum)

“…In the study of wood chemistry and especially in its application to the pulp and paper industry, cellulose, hemicelluloses, and lignin are the major natural polymer components. The usage of wood as the major source of raw materials for pulp and paper production has led to deforestation and inorganic chemicals for pulping causing environmental pollution has necessitated the search for alternatives (Jun et al 2016). The longer year of maturity of wood justi es the use of non-wood raw materials derived from biomass such as annual plants and agricultural waste for paper pulp manufacturing (Susi et al, 2015;Ruiz et al, 2011).…”

“…The basic knowledge is that lignin acts as cement that ties together the holocellulose parts of lignocellulosic biomass (Ashogbon, 2017). Cellulose is a linear, renewable, and biodegradable natural polymer material (Jun et al 2016;Habibi et al 2010). Due to its abundant renewable polymers, the use of cellulose is becoming increasingly important.…”
