Development of Nonwoven Insulation Material using Hemp Fibre

The increasing demand for sustainable and non-toxic insulation materials has emphasized the limitations of conventional glass wool, which is associated with skin irritation, respiratory issues, and environmental concerns. This study investigates the development of hemp Fibre -based thermal insulation as an eco-friendly and safer alternative. Hemp, being a renewable and biodegradable resource, provides excellent thermal insulation, breathability, moisture resistance, and non-toxicity. In this research, two types of nonwoven fabrics were prepared: a needle-punched nonwoven using 100% hemp fiber and a thermally bonded nonwoven using a hemp/polyester fiber blend. The study focuses on optimizing fiber treatment, exploring suitable nonwoven binding techniques, and evaluating the thermal and physical properties of both fabrics. The outcomes are expected to support sustainable construction practices by minimizing dependence on synthetic insulation and fostering the development of greener, healthier building materials. Results implies pure hemp offers better eco-friendliness, biodegradability, and compact insulation and the blend delivering enhanced flexibility, recovery, and air circulation, with reduced sustainability
