Effects of different retting methods on thermal stability and mechanical properties of hemp fibers

Abstract

Different retting methods were employed in hemp retting, treated hemp fibers by various retting methods were characterized by residual gum content, fineness, tenacity, elongation, and thermal gravimetric analysis. The results indicated that alkali-oxygen one bath process was satisfactory, which achieved hemp fiber with 2.14 tex, residual gum content 2.99% and tenacity 54.33 cN/tex.
