Study on thermal comfort behaviour of seams made of micro-denier polyester sewing thread for high active sportswear

Abstract

This work aims to investigate the thermal comfort behaviour of polyester seamed fabric regarding the change in sewing thread filaments fineness for two different seam classes: seam 514 and seam 607. Five seamed fabric samples were constructed with using micro-denier polyester filament of 16.66 tex made of five different filament numbers (38, 48, 108, 144 and 288). It was noticed that the seam thermal properties, air and water vapour permeability, and wicking can be improved if the seam is constructed with using the micro-denier polyester sewing thread. It was also found that the investigated properties increase with the increase in the sewing thread filament fineness on the seam line. The statistical results have also shown that the sewing thread filament fineness is significantly affecting thermal behaviour of the seamed fabric.
