In the context of bedding insulation materials, ensuring an optimum balance between physical properties, thermal resistance, and strength properties is crucial to provide optimum comfort. This study aimed to address this challenge by investigating the effect of blend ratio of bamboo to polyester fibres and feeder speed on the physical properties, thermal resistance, and tensile properties of needle-punched bamboo/polyester blended nonwoven batts. Bamboo fibres were treated and blended with polyester fibres, and then needle-punched to form nonwoven batts. Physical properties, including thickness, areal weight, density, and porosity, were measured to assess structural aspects of the nonwoven batts. Thermal resistance was evaluated using the Sweating Guarded Hotplate (SGHP) method. Tensile properties, such as breaking force, elongation at break and tensile strength, were analysed to assess the mechanical behaviour of the nonwoven batts. Analysis of variance (ANOVA) was employed to assess the effects of blend ratio and feeder speeds. Both blend ratio and feeder speed influenced thermal resistance. For tensile properties, blend ratio had a significant effect on breaking force, elongation at break, and tensile strength, while feeder speed had a significant effect on breaking force and elongation at break. Additionally, there was an interaction effect between blend ratio and feeder speed for breaking force and tensile strength. Samples with high thermal resistance exhibited low strength and were characterized by less thickness, low density, and high porosity. BP3-S2 sample exhibiting a thermal resistance of 0.1196 m²K/W and strength properties comprising a breaking force of 1.96 N and an elongation at break of 84.35%. The prepared nonwovens may find applications in insulating layers for blankets, quilts, and comforters while promoting the utilisation of bamboo fibres in this industry
