“…There must be a certain limit to the degree of heat and humidity of underwear, otherwise, there will be no comfort, but it will affect human health. However, at present, most researches on the influence of thermal and wet comfort of underwear on physiological activities only focus on the thermal and wet properties of fabrics [6][7][8][9][10][11][12], which does not involve the thermal and wet state of human body when wearing underwear. Even if some scholars have studied the thermal and wet comfort of underwear, they only use a kind of fabric or only study the static thermal and wet comfort.…”

In order to study the influence of underwear on human thermal and moisture comfort in different sports conditions, the objective and subjective evaluation of underwear (including undershirt and underpants) made of three kinds of fabrics were carried out, and the underwear comfort model was established by computational fluid dynamics, and the application prospect of computational fluid dynamics technology in the field of clothing comfort research was prospected. The results show: 1. the underwear combination of different fabrics has certain influence on the thermal and moisture comfort of human body, and the thermal and moisture of fabric of composite fiber is better than that of fabric of single fiber; 2. the temperature and humidity of chest, back, hip and thighs of the human body in different motion states change, and the temperature and humidity of the chest and back change greatly; 3. computational fluid dynamics can accurately predict human skin temperature.

“…Moisture absorbed by fabric material in a humidity environment or liquid water penetration into fabric will exact a significant impact on heat transport of clothing, which in turn influence comfort sensation of a wearer in practical wear situations [1,2]. Most textile materials are typically porous materials composed of plenty of macro-or meso-pore, and micro-pores [3].…”

The aim of this work reported in the paper is to investigate the influence of moisture content on the effective thermal conductivity (ETC) of non-hygroscopic Polyethylene terephthalate (PET) and hygroscopic Viscose (VC) fabrics using Parallel-Series (P-S) thermal-electrical analogy method and TPS measurement. An equivalent porosity for hygroscopic fabric was first proposed to preserve the validity of the P-S model. The equivalent porosity is characterized by reasonably eliminating the absorbed moisture effects partly, which is embodied in enhancing heat conduction, endothermic reaction and swelling. Calculated values of the effective thermal conductivity of the two kinds of fabrics had been compared with experimental measurements. Results show that the P-S model incorporated with equivalent porosity is found to yield higher prediction accuracy than that of P-S model with parent porosity. The calibrated model can also provide a robust tool for predicting the global effective thermal conductivity of moist hygroscopic fibrous porous media.

“…4,5 Textiles mixed with phase change materials provide an excellent cooling function, because there is significant decalescence of phase change when the temperature rises to a set value 6,7 according to the principle of energy conservation. Thus, the cooling sensation of fabric can be enhanced by improving heat conduction, moisture transfer and evaporation, 8,9 and using heat-absorption materials. Nowadays, some specific elements of the wet comfort of fabrics can be estimated, such as the liquid moisture transport property, moisture absorption and quick-drying capacity.…”

“…Therefore, it cannot display the integral hygroscopic and cooling function in a factual dressing. A sweating torso 9 was introduced to investigate combined heat and moisture transfer in three phases. However, the evaluation of moisture absorption, which is a key factor to measure the hygroscopic and cooling functions, was not involved.…”

The evaluation of thermal-wet properties contributes to the research and development of fabrics, but there is no effective method to address and achieve evaluation of the hygroscopic and cooling properties of knitted fabrics to date. Therefore, an evaluation method aiming at this issue was proposed, and based on experimental investigation the hygroscopic and cooling property of fabrics was estimated by the combined evaluation of moisture management and the thermal property in a dynamic state. The moisture management property shows the liquid water absorption and diffusion performance of fabrics. Beside this, the thermal properties of fabrics were tested respectively in the dry and wet states. The thermal property of dry fabric showed the heat transfer and radiation of fabric itself, whereas the thermal property of wet fabric demonstrated the combined effect of the coupled heat–moisture property of wet fabric and the cooling function of moisture evaporation and diffusion. Furthermore, the thermal properties of fabrics were tested using a YG606 II thermal resistance tester, which was refitted by a program to control heating power. Eight knitted fabric samples having different cooling comfortability rates or values were selected to verify the feasibility and effectivity of this method. The consistency of this method was also verified by the obtained experimental results. Based on the obtained results, it can be observed that this method was well consistent with verified experimental results. Therefore, an effective method for the evaluation of hygroscopic and cooling knitted fabrics was obtained that satisfies the measurement of performance, and desirable fabric properties can be achieved for various applications.
