These days, environmental issues are of great importance on a global scale. Carbon dioxide (CO₂) gas is typically released during the manufacturing and use of traditional metals, metal-based alloys or synthetic materials. For this reason, the use of bio-composite materials is increasing day by day in order to reduce the consumption of traditional metals, metal-based alloys or synthetic materials as bio-composite materials have less influence on the environment and they are biodegradable and eco-friendly. In this regard, environment-friendly materials like jute are of particular relevance. Jute is one of the most significant natural fibers that is found in large quantities in Bangladesh and it has been used for a variety of purposes. Similarly, like other natural fibers, jute fibers also have high moisture absorption qualities, which results in poor adhesion properties with the matrix and degraded material strength. Over the years, various methods have been used to improve moisture absorption ability and fiber to matrix adhesion properties. Among various methods, chemical treatment is the most widely used method. Chemical treatments can be considered for modifying the properties of jute fibers. It can increase the interface adhesion between the jute fiber and the matrix. It can also decrease the water absorption of fibers. Yet most chemical treatments have achieved various levels of success in improving jute fiber’s strength, fiber fitness and fiber-matrix adhesion. Therefore, the goal of the current study is to understand how chemical treatment affects the mechanical properties of jute fiber.
