Water absorbency of wheat straw paper treated with gelatin & carboxymethyl cellulose.

Abstract

Chapter I consists of; the introduction which includes a background on how water absorbency affects paper properties, brief information about wheat straw, gelatin and carboxymethyl cellulose; the problem statement, justification, objectives, and scope. Chapter II provides a literature review giving a bit more detailed work on studies already existing in line with the project, treatment with gelatin and carboxymethyl cellulose in pulp and paper. Chapter III presents the materials to be used, how they are to be pre-treated in preparation for papermaking and the methods to be used in order to achieve the aim of the study. Chapter IV includes the results and their discussion of the study. Chapter V is the conclusion and recommendation. An appendix containing some images that were taken during project implementation is given. The pulp and paper industry around the world has been growing rapidly. As a result, there has been a huge demand for pulp and paper making raw material. Recent years have seen a spurt in use of non-wood fibers being used as a raw material for this purpose. Although some of the nonwood fibers used for papermaking are used because of their fine paper making qualities, majority of non-wood fibers are used to overcome the shortage of wood fibers. Right from supply of raw material to the properties of finished paper, majority of non-wood raw material has proven to be economically inferior to wood. But over the last few years, technological breakthrough in almost all the fields of papermaking have made non-wood more competitive with wood as a raw material for papermaking.
