Effect of Chemical Treatment on Mechanical Properties and Moisture Regain of Jute Fibers

Abstract

We report on the moisture regain, relative vapor pressure, hysteresis, and mechanical properties of two varieties of jute fibers. Corchorus capsularis grade 2 and Corchorus olitorius grade 2, modified by treatment with sebacoyl chloride, tolylene diisocyanate unsaturated polyester resin, vinyl ester resin, γ-aminopropyl trimethoxy silane, and isopropyl triisostearoyl titanate. All the treated fibers showed a reduction in moisture regain, but some fibers had superior moisture repellent behavior with no deterioration in their mechanical properties, while others suffered a loss in mechanical properties.
