Effect of Blending of Sisal on Pulp Properties of Waste Papers in Handmade Papermaking

Abstract

In an attempt to improve the quality of the waste paper in recycling in paper manufacturing, sisal (a hard fiber) is blended with. The proximate analysis of sisal fibre has been compared with that of the kenaf and waste paper. A high cellulose content in sisal (67.19%) than the kenaf bast fibre (63.5%) and a slightly less lignin percent of sisal (10.22) in comparison to kenaf (12.7) suggest the suitability of sisal fiber for better pulping efficacy and hence paper making. The high tensile strength of sisal fiber is an important cause for blending with weak recycled fibers of waste paper. The preparation of strong paper has been optimized by varying the amount of constituents and modifying sisal fibers.
