Investigation on impact of bell pique weft knit fabrics on geometric and comfort properties

Thermal Comfort

Abstract

This study investigates the thermal comfort and moisture management properties of knitted fabrics using two different pique knit structures: single tuck pique and bell pique. The impact of knit structure on various geometric and comfort properties is evaluated, including loop length, wales per inch, course per inch, tightness factor, bursting strength, fabric thickness, GSM, fabric stretch, air permeability, warmth retention rate, thermal transmittance coefficient, thermal resistance, CLO, and moisture management. To construct the fabrics, a yarn linear density of 24s Ne is used, and three different loop lengths (0.265 cm, 0.285 cm, and 0.305 cm) are tested for each knit structure. The goal of this research is to compare the performance of these two knit structures and determine how they affect the comfort properties of the resulting fabrics. It is observed that the bell pique structure exhibits better comfort properties than single tuck pique at two loop lengths, and it may help the fabric manufacturers and designers in selecting the appropriate fabric structure based on the desired comfort properties.
