As the primary skin-contact layer, lining fabrics dictate clothing comfort and functional potential while enduring stressors like perspiration and mechanical tension. Consequently, defining their specific material composition is essential for ensuring physiological harmony. Therefore, the purpose of this study is to empirically evaluate the effect of filament fineness as a determinant of performance metrics in polyester microfiber lightweight lining fabrics.
Design/methodology/approach
This study investigates how filament fineness, weave structure and weft density determine the characteristics of polyester microfiber woven lining fabrics. Two filament fineness values were used to fabricate 12 samples, which were then evaluated for physical, mechanical, comfort and protection properties.
Findings
Statistical analysis of the tested properties indicates that finer filaments significantly influence the weight and thickness of lining fabrics. The results show that finer filaments improve breaking strength, promote wicking ability and enhance thermal insulation. Additionally, they contribute to robust UV protection and effective electrostatic discharge properties. Conversely, the use of finer filaments results in increased stiffness while decreasing both air and water permeability.
Originality/value
This empirical evaluation provides novel insights indicating that filament fineness has a substantial effect, which becomes increasingly pronounced as weft density decreases. Unlike previous studies that primarily focus on outerwear or sportswear, this research uniquely maps the multi-dimensional performance of lightweight linings – including protective properties (UPF and electrostatic discharge) – and uses a comprehensive radar-chart quality index to identify optimal structural combinations. Furthermore, thermal conductivity was identified as the most affected property, in contrast to electrostatic charge. Finally, based on the performance index, the most suitable sample was found to be the one with the plain weave structure.
