Study on the influence of underwear on local thermal and moisture comfort of human body

Abstract

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.

Thermal comfort properties of bi-layer knitted fabrics made up of polyester yarns and nylon yarns with varied specification

“…Textiles with excellent comfort performance are gaining more interests in the global market as the living standards improved. Therefore, the effect of fabrics and their interactions with human skin has been a renowned area for researchers (Sathish Babu et al ., 2020; Cheng et al ., 2021). Generally, a great thermal and moisture management capacity of fabrics is considerable in improving the comfort properties of clothing (Eryuruk, 2020; Angelova et al ., 2017), especially for summer and sports clothing.…”

Quality of Fine Yarns from Modacrylic/Polyacrylate/Lyocell Blends Intended for Affordable Flame-Resistant Underwear

“…Regardless of the recommendations, firefighters in particular do not wear flame-resistant underwear but ordinary underwear, mainly made of cheap cotton or polyester [ 8 ]. Polyester underwear is particularly popular among firefighters because it is soft, easy to wash, and durable, and because there are several attractive designs available on the market [ 9 , 10 ].…”

“…Polyester underwear is particularly popular among firefighters because it is soft, easy to wash, and durable, and because there are several attractive designs available on the market [ 9 , 10 ]. In moderate-temperature environments, good moisture management allows underwear made of blends of cotton or lyocell with elastane to provide good adhesion to the skin and rapid absorption of sweat from the skin [ 8 ]. Polyester microfibre underwear is also very effective in removing sweat from the skin by wicking [ 4 ].…”
