Innovating sustainability: a holistic approach to insulation panel design from woven sewn-in label selvedge wastes

The textile industry stands out as a significant contributor to environmental pollution, with its escalating material consumption exerting a considerable impact on the ecosystem. The surge in textile waste has spurred a heightened interest in recycling initiatives, particularly focused on transforming textile waste into functional technical products. In response to the increasing demand for insulation materials driven by the imperative to conserve building thermal energy and address rising noise pollution, recycled textile materials have gained prominence for their application in thermal and acoustic insulation. This research delves into the efficacy of insulation materials developed from woven sewn-in label selvedge waste, comprised entirely of polyester fiber. Employing carding and needle punching methods, nonwoven panels are produced from label wastes. Tests are conducted to evaluate the thermal, acoustic, and air permeability attributes of panels varying in thickness and weight. The findings reveal that the thickest panel excel in acoustic insulation, whereas the thinnest panel with least density exhibit notable thermal efficiency and air permeability characteristics.
