Extraction and characterization of Alfa fibers and their use to produce Alfa/wool woven fabrics for composite reinforcement

摘要: Because of their appealing properties, such as biodegradability, high basic stiffness, low density, and low cost, natural fibers have begun to be used in a variety of applications. In comparison to synthetics, they are also reusable. The aim of this work is to develop new woven materials made of wool and Alfa fibers (Stipa-tenacissima). The extraction of Alfa fibers was achieved via alkaline treatment. The chemical composition, mechanical and physical properties of the extracted fibers were determined. Wovens were produced using the weaving of taffetas technique. This study presents a chemical, physical, morphological and mechanical characterization of Alfa/wool yarns and fabrics. The results show that the fabric made of fibers treated with 2 mol concentration of NaOH presents the greatest morphological structure and a higher degree of crystallinity due to the reorganization of the molecular chains that results in a …
