The effects of environmental conditions on the mechanical properties of jute yarns

In the last years, the natural fibers have been used in many fields such as composites, auto industry and textiles. The natural fibers are chosen due to their renewability, their biodegradability, the presence with a large amounts and their eco-friendly environmental characteristic. Jute fiber is one of the most tropical fibers produced in the Bangladesh and the India. But, the mechanical properties of these fibers in environmental conditions are influenced by the evolution of the chemical and physical modifications induced inside of the fibers. This work aims to investigate the effects of different environmental conditions on the thermal stability of the jute yarns and their mechanicals properties. The obtained results show that the change in the mechanical properties is correlated with water dried and uptake. The jute yarns stress reduction can be primarily explained by the plasticizer role of water molecules and the friction reduction between fibers. (c) 2019 Elsevier Ltd. All rights reserved.
