Abstract

This research is aimed at studying the impact of micro-denier polyester filament on seam thermal comfort properties.
Sewing threads of 150 deniers have been proposed from textured micro˗denier polyester filaments with five different
filament numbers (3.94 dpf, 3.1 dpf, 1.38 dpf, 1.04 dpf, and 0.52 dpf), calculated based on the number of the filament within
the specified fibre diameter. The stitch density (10 stitches per inch) has been used. It is observed that the air permeability
and water vapour permeability increase with an increase in sewing thread filament fineness on the seam line. The thermal
properties of the seamed fabric are highly influenced by the sewing thread filament fineness. Micro filaments of the sewing
thread improve the thermal conductivity of the seams. Air permeability and moisture vapor transmission rate increase as the
fineness decreases in the micro-denier range. All the results are statistically analyzed using ANOVA at 0.05 significance
levels. The statistically analyzed results show that the sewing thread filament fineness is significantly affecting the thermal
properties of the seamed fabric.
