The effect of garment combinations on thermal comfort of office clothing

Abstract

Clothing and the enclosed air layers highly affect heat dissipation from the body and thus, are crucial factors when it comes to thermal comfort. The heat and moisture transfer is affected by the variation of the size and the shape of air gaps between the garment and the human body. In addition, the fabric and garment design properties can affect the amount of heat loss from different body parts. In this study, we investigated the effect of fabric properties (different raw materials and weave types) and the garment fit on the heat loss through the garment combinations (undershirt and shirt) for the different parts of the upper body (trunk, chest, and back) using a sweating thermal manikin. The undershirt fit and the raw material of the shirts showed strong effects on the dry thermal resistance of the garment combinations. Moreover, the undershirt properties affected the evaporative heat loss from garment combinations, and the magnitude of these effects varied over different body regions. Whilst the undershirt fit had a significant impact on the evaporative heat loss of the back region, the influence of the undershirt raw material was more important in the chest region. The findings of this study provide fundamental knowledge to improve the thermal comfort of garment combinations for office wear.

Effect of knitting structure and yarn composition on thermal comfort properties of bi-layer knitted fabrics

“…It is generally known that there are three forms of dry heat exchange, convection, conduction and radiation, between the human body and the environment. In fact, this dry heat exchange is not effective enough to release heat from the human body after sweating excessively, and excessive heat has a negative effect on thermal comfort and work efficiency, 2 whereas the sweat evaporation increases the heat loss according to the principle of energy conservation, which is crucial for the cooling function of clothing. Moreover, it has been verified that poor thermal or moisture transfer properties of fabrics diminish their overall comfort 3 and even threaten human health 4 due to bacteria breeding in the excessive sweat.…”

Big data and digital design models for fashion design

“…fitting style, fabric properties) need to be considered. [58][59][60] Li et al [61][62][63] developed an online CAD system, called e-Thermal, to satisfy designers' and manufacturers' requirements for thermal functional design. This system considers all key aspects affecting human body-wear comfort.…”

Research on sensory comfort of tight-fitting sportswear based on intelligent models

“…By summing up the existing research and the authors' research experience, this paper regards the shoulder, armpit, bust, back, back waist, body side, upper arm (inside and outside upper arm), elbow, forearm (inside and outside forearm), hip, thigh (inside thigh, outside thigh, back thigh), knee, shank, abdomen, and crotch as the initial evaluation parts of local comfort.
