This project focuses on the physicochemical characterization of vegetal species from Malvaceae family and the study of the properties of these fibers. Vegetal fibers can be used not only for fabric, but also for the production of yarns, ropes, nonwovens, composites substituting that ones manufactured from wood or synthetic materials. Brazil has great potential regarding to the variety of natural fibers and their study can aid the development, not only from textile industry but also the country's economic development. The research will consist of physicochemical characterization of 06 vegetal species already collected, from Malvaceae family: Sida cordifolia L, Sida carpinifolia L. f.; Sida rhombifolia L; Sidastrum paniculatum (L.) Fryxell; Wissadula subpeltata (Kuntze) R. E. Fries and Malvastrum coromandelianum (L.) Gurck, which will be subjected to physical tests of elongation, elasticity and resistance held in tester machine; determining the moisture content and regain, fiber density determination, chemical combustion tests, determination of aqueous extract pH, the effects of organic solvents, alkalis, acids, and the determination of cellulose, hemicellulose and lignin contents. This research will lead to acquisition of knowledge about our flora and their employability, enabling new publications and patents about application of these fibers.
