For these reasons, natural fibres are more attractive to researchers and scientists as an alternative source of reinforcement to develop organic polymer composites. Kenaf Fibers and Page 15/18 However, longer fiber shave better tenacity (measure of strength) and modulus ( measure of stiffness) found a positive change in tenacity with the increase in length array groups. The addition of luffa fibers (LFs) as a reinforcement constituent of composite material resulted in the advancement of the mechanical properties like tensile, compressive, flexural, impact strength, and water absorption characteristics of a material [ 98 ]. The mechanical properties of three types of bars are studied in this paper: Cotton Fibre-Reinforced Polymer bars, Cotton/Carbon Fibre-Reinforced Polymer bars, and Cotton/Glass Fibre-Reinforced Polymer bars. Drean Source: Textile research journal 2010 v.80 no.11 pp. fiber-reinforced composites and their structures and characteristics need to be investigated. Mechanical Properties of Textile Fibers The mechanical properties of textile fibers are the responses to applied forces and deformations. Cotton fiber is very hygroscopic due to the presence of a large number of -OH groups. 1. Longer staple fibers are higher-grade cotton and are sold at higher prices. Properties of Cotton | Cotton Fiber Properties | Cotton Manufacturing They discard most of the cotton until just a pinch of well-aligned fibers remains. The changes in fiber mechanical properties due to mercerization were found to be highly dependent upon the tension exerted on the fiber during the treatment. Recently, a number of researchers have been focused on the modification of mechanical properties of CRC. Properties of Cotton Fibre (Physical, Chemical and Technical Properties) Hemp fibers are one of the strongest and most durable among all of the natural textile fibers.
