A Method for the Manufacture of Paper Pulp from Okra Stem Fibers

Abstract

This paper presents an environmental-friendly method to make a pulp starting from okra stem fibers. The lignin was removed using three treatment methods: Mon ethanolamine, Mon ethanolamine- Anthraquinone, Sodium Bicarbonate - Anthraquinone. The conditions of the experiments were optimized and tested in order to reach the optimal conditions of pulping. The experiments showed that the ultimate conditions to get high mechanical properties of the pulp fromokra stem fibers were when using a 50% Mon ethanolamine and0.3 % Anthraquinone at a temperature of 140^o C for 100 min. The yield was “55.8 %”, the number of kappa “20”, the tensile index was high “20 N. m²/g”, the tear index was “5.8 N.m²/g” at 0.05 significance level, the burst index was “1.2 kPa.m²/g”, and the breaking length was 1.75 km.
