This study aims to assess the performance benefits of neppy yarn in knitted fabrics produced from vortex and ring spinning techniques. It explores neppy yarns, thermal and mechanical properties for sustainable and comfortable textile applications.
Six fabric samples were knitted from neppy yarns produced by vortex and ring spinning, and their thermal and mechanical properties were systematically evaluated. Key parameters analyzed included thermal resistance, CLO value, thermal conductivity, transmittance, air permeability, bursting strength, dimensional stability and spirality. All test results were analyzed numerically and evaluated statistically using one-way analysis of variance.
The experimental results reveal that vortex-spun neppy yarn (VSNY) fabrics demonstrate higher insulating capacity, lower heat transfer and increased air permeability relative to ring-spun neppy yarn (RSNY) fabrics. VSNY fabrics also show superior resistance to twisting and distortion, indicated by their excellent spirality values. However, they exhibit lower dimensional stability and bursting strength than RSNY fabrics.
This study highlights the potential of vortex-spinning techniques in producing sustainable, comfortable textiles by leveraging the unique properties of fancy yarns. It provides valuable insights into the environmental and performance advantages of neppy yarn fabrics, particularly those produced through vortex spinning, in the textile industry.
