520			_aThis study developed and evaluated thermal property of denim textile fiberboard using isocyanate as binder in response to growing demands for sustainable, non-wood construction materials. Addressing the research gap involving the limited use of denim fibers in engineered composites and the lack of performance data on denim–isocyanate bonding behavior, the study aimed to formulate five mix ratios, determine their thermal conductivity, and assess mechanical and physical properties based on PNS ISO 8302:2021 and PNS/ISO 16895:2017. Using an experimental design, five board formulations (97:3 to 89:11 denim– isocyanate ratios) were fabricated at a target density of 0.8 g/cm3 and subjected to tests including Modulus of Rupture, Modulus of Elasticity, Internal Bond Strength, Thickness Swelling, Water Absorption, and Thermal Conductivity. Results showed that higher isocyanate content improved MOR, IB, and dimensional stability; however, none of the samples met minimum PNS requirements for internal bond, stiffness, wet bending, or swelling limits. The thermal conductivity was within the range expected from natural fiber composite materials; however, it did not meet the performance requirement for high thermal resistance. This paper finds that although the composite material has a positive trend, there is a need to optimize the binder-to-fiber ratio, among other considerations. The research contributes to UN-SDGs on responsible consumption, sustainable manufacturing, and waste reduction by demonstrating the potential of recycled denim as an eco-friendly composite material.
