Abstract
The compressive nature of textile fabrics is known to be a significant factor influencing tactile comfort. In addition, the transport of the heat through the fabric is considered to be the major factor in thermal comfort. Since the thermal behavior of textile fabrics is highly correlated with thickness and porosity, the changes in bulk density of the fabric caused by the compression force would change the heat flux through the fabric. The operation of yarn folding modifies the existing single yarns to an appreciable degree by combining them together. Therefore, in this study the interaction of thermal and compression properties of textile materials was analyzed from the aspect of the operation of yarn folding. Two jersey knitted fabrics were compared, both knitted under the same conditions, the first produced from the single hemp yarn, and the second one produced from the two-folded hemp yarn. The knitted fabrics exhibited comparable thermal properties. The differences in their compressibility indicated that the reduction of thermal conductivity under the compression force is more likely to be higher for the knitted fabric consisted of the folded yarn. Since the resilience of the knit made from two-folded yarn was comparable to that of the single yarn counterpart, similar permanent changes in thermal behavior of these knits could be expected.
