Quality improvement of paper from bamboo and hardwood furnish through fiber fractionation

Abstract

This study is aimed to improve the quality of paper made from hardwoods (70-80%) and bamboo furnish (20-30%) through fractionation process. The fiber fractionation followed by selective processing of each fraction proved to be a better option to produce paper of improved quality in terms of strength, optical and printing properties. The paper also discusses the machine runnability with fractionated pulp samples based on Wet web properties and fines content of fractionated pulp. The possibilities of using different fractions in different grades were also explored. This is a good opportunity for mills having multiple paper machines and making different varieties of paper.
