Fabric low load compression-recovery behaviour has been analysed by defining initial thickness, compression parameter, recovery parameter and resiliency. Fabrics made from coarser yarn (larger total yarn dtex) have higher initial thickness and compression parameter while lower recovery parameter and resiliency, as compared to fabrics made from finer yarn. Fabrics are woven with two woven structures, namely plain and twill weave to assess the effect of fabric structure on compression and recovery behaviour of the fabrics. Twill woven fabrics exhibit a higher value of all compressional parameters compared to their equivalent plain woven fabrics. Parent yarn fabrics exhibit a low value of all compressional properties, irrespective of change in any feed yarn characteristics as compared to their equivalent textured yarn fabrics.

The yarn liveliness is altered by changing draw ratio on ring frame and thus the elastane core % in the yarn. The 4 samples of 30s Ne elastane core-spun cotton yarn have been produced using 40 den elastane having 5, 7, 9 and 11% elastane core adjusted by using suitable draw ratio on ring frame. These elastane core-spun cotton yarns are used in weft direction to produce fabric sample. These fabric samples are tested for various physical and mechanical properties as per ASTM standards. The findings reveal that the yarn core liveliness has significant effect on various physical and mechanical 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.

The carpet samples are first subjected to different UV exposure time and then dynamic loading is imposed to the samples. In each case, the thickness loss of the carpets is measured. The results show that the UV exposure time has a slight effect on the thickness loss of the carpets. The number of dynamic impacts, on the other hand, shows a significant effect on the thickness loss with an exponential correlation. Using best curve fitting method based on least square method, a predicting equation is derived for the multiple effect of UV exposure time and number of dynamic loading on the thickness loss. The experimental verification reveals that the proposed predicting equation can be used with an acceptable accuracy.
