Abstract
The environmental sustainability level is enhanced while using natural fibers as raw material in various industries like textile, building, plastics, and automotive industries due to acquiring properties like non-hazardous, light weight, recyclable, ample and reasonably priced. Terminalia Catappa fruit fiber is one such type fiber which was extracted from Terminalia Catappa fruit. The physical and chemical properties such as density, cellulose, wax, moisture, were experimentally found out from this fiber. In this paper, the Terminalia Catappa fruit fibers were treated with 5% and 10% of NaOH and the consequence of alkali treatments on the fiber properties were investigated.
