The objective of this paper is to report a study on the prediction of the steady-state thermal resistance of woven compression bandage (WCB) by using three different mathematical models. The experimental samples of WCB were 100% cotton, cotton–polyamide–polyurethane, and viscose–polyurethane. The bandage samples were evaluated at extensions ranging at 10–100%, with two- and three-layer bandaging techniques. Experimental thermal resistance was measured by thermal foot manikin (TFM) and ALAMBETA testing devices. The obtained results by TFM and ALAMBETA were validated and compared with the theoretical models (Maxwell–Eucken2, Schuhmeister, and Militky), and a reasonable correlation of approximately 78%, 92%, and 93% for ALAMBETA and 75%, 82%, and 83% for TFM, respectively, was observed.

“…Single jersey knitted fabrics (SJKF) are used for under-and outer-wear compared to woven fabrics because of their high extensibility (compression and elongation of individual stitch) [4]. To enhance the dimensional stability and maintain the dimensions during use and after repeated stresses of knitted fabrics, the additional Lycra (full-and halfplaited) and core-spun yarn are used [5]. Lycra is the trade name of elastane (spandex) yarns.…”

“…It was noticed that the air permeability, total hand value, overall moisture management capacity, and the water vapor permeability of stretched SJKF are lower than the corresponding values for 100% cotton fabric sample. Thermal absorptivity of core and dual-core samples increased when compared to 100% cotton fabric sample [5]. The thermal comfort properties of SJKF produced from cotton/Lycra core spun yarn and cotton/additional Lycra ( fp) were investigated.…”

“…It was reported that there is a convergence of the measured properties' values between the fabric samples produced from core spun yarn and cotton yarns with additional Lycra. Lycra state had a significant effect on thermal conductivity and air permeability and an insignificant effect on thermal resistance, absorptivity, and relative water vapor permeability [17]. So, more researches are required to investigate the effect of Lycra percent, loop length, and Lycra state on thermo-physiological properties of elastic knitted fabrics.…”

The aim of this work is to estimate the effect of loop length and Lycra weight percent (Lwp) on the geometrical and thermo-physiological comfort of elastic plain knitted fabric. Fifty single jersey knitted fabric samples were produced at five levels of Lycra weight percent (Lwp) (4%, 5%, 6%, 7%, and 8%) and loop length (2.7 mm, 2.9 mm, 3.1 mm, 3.3 mm, and 3.4 mm) with full plaited (fp) and half plaited (hp) of bare Lycra. The thermo-physiological comfort properties (thermal conductivity, absorptivity, and water vapor permeability), air permeability, and geometrical properties were measured at standard of each one. The results showed that the elastic single jersey knitted fabric thickness ranged between 3.12 times and 4.2 times of the yarn diameter (d). The fabric thickness increased when loop length is increased and decreased when Lwp is increased. The thermal conductivity, absorptivity, and water vapor resistance (WVR) decreased with Lwp increasing.

“…The researchers concluded that the permeability properties of the knitted fabrics produced with cotton, viscose, and PES fibres in the sheath and PVA in the core were positively affected [31]. Khalil et al [2020] studied the thermal comfort properties of 100% cotton, cotton with full-platted Lycra, Core, and Dual Core spun yarns (DCS). It is concluded that the core spun and DCS show the highest elongation 27% increased thermal conductivity 18% decreased water-vapour permeability which gives extensibility and comfort at the same strength compared to 100% cotton samples [32].…”

This study, mainly focused on the effect of core-sheath ratio, twist and stitch length on the thermal comfort properties of single jersey knitted fabrics produced from various ratios (100:0, 80:20 and 60:40) of cotton/ polyester core spun yarns. The Box-Behnken design tool was used to study coresheath ratio, twist and stitch length on the thermal comfort properties of single jersey knitted fabrics and response surface equations were derived and design variables were optimized. From this study, the findings reveal that the decrease in cotton ratio among the fabrics made from core spun yarns decreases the fabric thickness and hence a more porous structure that results in higher thermal conductivity, air permeability, water-vapour transmission and less thermal resistance. It is also evidenced that, increase in the yarn twist (high) and the stitch length (tight) in the fabric structure makes thicker and less porous fabric which results in higher thermal resistance and lesser thermal conductivity, air permeability and water-vapour transmission.
