An Experimental Study on the Effect of Mercerization Parameters on the Variation in the Chemical Composition and Mechanical Properties of Natural Fibers: Coir
Natural fibers possess inherent variation in their chemical composition and hence in their mechanical properties, which trickles down into the composites being manufactured.

| Summary: | Natural fibers possess inherent variation in their chemical composition and hence in their mechanical properties, which trickles down into the composites being manufactured. The experimental study has been conducted to assess the possibility of minimizing these variations by optimizing the surface treatment parameters. Coir fibers were subjected to NaOH treatment at various concentrations, time, and temperature parameters as ascertained by the Box-Behnken design. The optimum parameters identified are 8% NaOH at 25°C for 480 min, which resulted in higher fiber crystallinity, rougher surface, and an increase in maximum tensile force. The variation in lignin and maximum tensile force reduced by 22.415% and 39.571%, respectively. |
