Abstract
The purpose of this study is to develop a high strength paper fabricated with
bamboo single fibers. The fibers were extracted from Moso bamboo trees
between two months to four years old. The experiments in this study showed the
differences of mechanical properties and dimensions of single fibers according to
the age of the bamboo. The mechanical properties of the paper fabricated with
the bamboo single fibers were also measured. To increase the adhesive area of
bamboo fibers in the paper, parenchyma cells were additionally supplied into the
material of the paper. The effect of the weight content of the parenchyma cell on
the tensile strength was discussed to determine the appropriate ratio of
enhancements.
The superior mechanical properties of elastic modulus and the tensile strength
of single fibers were obtained when relatively young bamboo was selected as the
material. Two year old bamboo has proper parenchyma cells for the heat-sealing
between fibers to improve the strength of paper fabricated with bamboo fibers.
The tensile strength of the paper was improved when the bamboo paper
contained 10% parenchyma cells by weight.
Keywords: bamboo, paper, parenchyma cell, single fiber, adhesion, age of
bamboo, cellulose.
1 Introduction
World paper consumption was about 300 million tons in 1996/1997 and is
expected to rise above 400 million tons by the year 2010 [1]. In view of the
shortage of conventional raw materials for pulping and increasing demand for
paper products worldwide, bamboo, which grows quickly, has attracted public
