Effect of yarn type on knitted fabric thermophysiological comfort

The knitted fabric thermophysiological comfort is influenced by fabric characteristics and structure, including yarn spinning and finishing process. The research on viscose double jersey knitted fabrics knitted from ring, rotor and SIRO spun yarns counts of 20 tex were carried out. Beside the knitted fabric structure parameters analysis, thermal and water vapour resistance using the Sweating Guarded Hot Plate according to standard ISO 11092:2014 were determinate. The yarns made by different spinning processes have an impact on the knitted fabric structural parameters, thus on thermal and water vapour resistance. The greatest reduce of the thermal resistance were obtained after finishing process of knitted fabric made by SIRO yarn. Greatest difference in the water vapour resistance is between knitted fabrics made of ring and rotor yarns.
