Thermal behaviour of ring- and compact-spun yarn single jersey, rib and interlock knitted fabrics

Abstract

The effect of thermal behaviour, such as thermal insulation, thermal conductivity and thermal diffusion, of single jersey, rib and interlock knitted fabrics made out of ring- and compact-spun yarns has been studied. The physical characteristics, such as fabric aerial density, air permeability, tightness factor, and fabric thickness, have been studied and their relationship with thermal behaviour using multivariable ANOVA analysed. The experimental results show that the thermal conductivity, thermal diffusion and thermal resistance of the knitted fabrics depend on the fabric properties such as thickness, tightness factor, aerial density and air permeability. It is found that the compact-spun yarn knitted fabrics (Sussen Elite and Com4) show higher thermal insulation behaviour in all the knitted structures in comparison to ring- spun yarn knitted fabrics.
