 Full text | Abstract: This study is a continuation of experimental analyses to determine the thermal properties of socks. The influence of yarns from the different natural fibres of socks on the thermal conductivity coefficient of plain knits and plated plane knits with textured polyamide (PA) or elastane thread was assessed in Part I. The influence of the fibre yarns mentioned on thermal resistance was analysed. It was determined that a higher thermal resistance is characteristic for knits with Lycra thread, lower – for knits from pure yarns, and the lowest- for knits with textured PA thread. It was found that an increase in linear density occurs when there is a decrease in thermal resistance, especially in a combination with two pure yarns and one plated textured polyamide or elastane Lycra thread. The thermal resistance of samples manufactured from pure yarns and from a composition with PA thread was lower compared with samples which have Lycra thread. |
