Effect of surface treatments on the cross-section area and on the tensile properties of sisal fibers

ABSTRACT

This work deals with the effect that surface treatments can cause on the cross-section and on the tensile properties of sisal fibers. The simplest treatment of washing in tap water, at room temperature and at 60°C, was compared with mercerization treatment. The observed variation of the tensile properties is partially due to modifications caused at the cross section of the fibers due to the treatments, and also by structural modifications caused by removing fiber’s constituents or by promoting structural modifications due to shrinking of cell wall. Although much more aggressive to the environment mercerization was much more effective to enhance the mechanical properties of the fiber.

摘要

本文研究了表面处理对剑麻纤维截面和拉伸性能的影响。最简单的自来水冲洗处理，在室温和60°C，与丝光处理相比。所观察到的拉伸性能的变化部分是由于纤维在处理时的横截面引起的改变，也可能是由于纤维成分的去除或由于细胞壁收缩导致的结构改变而引起的结构改变。虽然更为积极的环境市场化更有效提高纤维的力学性能。
