Abstract: The effect of thermal treatment (dry and wet) under slack conditions, blend ratio and fibre cross-section on the structure and properties of air-jet spun yarns has been studied. It is observed that the thermal treatment, particularly in wet condition, increases the linear density, helix angle, helix diameter, breaking extension and abrasion resistance and decreases the mean fibre extent, tenacity and flexural rigidity of the yarns. The increase in amount of coarser denier fibre exhibits higher helix diameter, mean fibre extent, yarn tenacity, breaking extension, abrasion resistance and flexural rigidity, and lower helix angle. The increase in trilobal fibre content in the blend shows increased helix diameter and mean fibre extent, and lower helix angle, yarn tenacity, breaking extension, abrasion resistance and flexural rigidity in the yarn.
