“…Further Tariq Mansoor et al (2019) performed research on the thermal resistance of plain socks with various fiber compositions, and the experimental results showed a good agreement with theoretical values. It was discovered that when the moisture level in the fiber increased, the thermal resistance of all of the fiber compositions decreased (Mansoor et al , 2019). Mansoor et al (2020) developed a new technique for measuring the heat resistance and comfort characteristics of simple socks with various fiber compositions while they were wet.…”

Purpose Perspiration and heat are produced by the body and must be eliminated to maintain a stable body temperature. Sweat, heat and air must pass through the fabric to be comfortable. The cloth absorbs sweat and then releases it, allowing the body to chill down. By capillary action, moisture is driven away from fabric pores or sucked out of yarns. Convectional air movement improves sweat drainage, which may aid in body temperature reduction. Clothing reduces the skin's ability to transport heat and moisture to the outside. Excessive moisture makes clothing stick to the skin, whereas excessive heat induces heat stress, making the user uncomfortable. Wet heat loss is significantly more difficult to understand than dry heat loss. The purpose of this study is to provided a good compilation of complete information on wet thermal comfort of textile and technological elements to be consider while constructing protective apparel. Design/methodology/approach This paper aims to critically review studies on the thermal comfort of textiles in wet conditions and assess the results to guide future research. Findings Several recent studies focused on wet textiles' impact on comfort. Moisture reduces the fabric's thermal insulation value while also altering its moisture characteristics. Moisture and heat conductivity were linked. Sweat and other factors impact fabric comfort. So, while evaluating a fabric's comfort, consider both external and inside moisture. Originality/value The systematic literature review in this research focuses on wet thermal comfort and technological elements to consider while constructing protective apparel.

“…[21][22][23][24] Heat transfer through the high bulk nonwoven fabric is considered a coupled conduction-radiation problem. [25][26][27] Mansoor et al 28 studied the effect of moisture percentage on the thermal insulation provided by the plain socks numerically and validated with experimental results. They found a good correlation between experimental and numerical outcomes of thermal insulation for different numerical models.…”

In extreme cold weather clothing ensemble, multiple layers of high bulk nonwovens are used to provide thermal insulation to the wearer. In this work, the effect of layering sequence in multi-layered high bulk thermal bonded nonwoven assembly on its thermal resistance is evaluated experimentally under sub-zero temperatures. Two multi-layered nonwovens, one made up of 1.4 denier solid (1.4 D S), 6 denier hollow (6 D H) and 15 denier hollow (15 D H) and the second made up of 3 denier hollow (3 D H), 6 denier hollow (6 D H) and 15 denier hollow (15 D H) polyester fibres were studied. The experiments were performed in a climatic chamber in the temperature range of 310 K to 210 K. Numerical simulations were carried out assuming heat transfer through the nonwovens as one-dimensional coupled conduction-radiation. The numerical methodology was developed using theoretical relations available in the literature to estimate the steady-state temperature profiles through the nonwoven layers and were validated using experimental data. The concurrence of experimental and numerical temperature profiles justifies the numerical methodology adopted in this work. Thermal resistance provided by the high bulk nonwoven increases with a decrease in ambient temperature. It is found that the thermal conductivity of nonwoven layers decreases from inner-to outer layers at a given ambient temperature. The heat flux through nonwoven layers, overall thermal conductivity and the thermal resistance of multi-layer nonwoven are independent of layering sequence if the convective heat transfer is extremely low.

“…Later, many researchers used Schuhmeister's model by assuming different ratios of series and parallel components [22][23][24]. Presently, Mansoor et al [25,26] have modifi ed Schuhmeister and Militky models by combining the water and fi ber fi lling coeffi cients for the prediction of thermal resistance of wet socks.…”

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.
