Fabric comfort by modifying yarn structure: Part II-Low-stress mechanical, thermal and transmission characteristics of fabrics

The present study aims at investigating the influence of yarn structure, modified through process parameters of ring frame (spindle speed, twist multiplier and ring frame draft), on low-stress mechanical, thermal properties and transmission properties of fabric. It is observed that the structural changes influence thermal, transmission and low-stress mechanical characteristics of fabrics due to change in fabric porosity and thickness. In general, the bending and compression properties increase but shear and surface properties of the fabrics decrease with the increase in spindle speed, twist multiplier and draft. The study further reveals that air permeability, thermal absorptivity, thermal diffusivity, heat conductivity and moisture transmission properties increase but thermal resistance decreases with the increase in spinning process parameters.
