250-257The 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
