Abstract
Consumers expect high-performance functionality from sportswear. To meet athletic and leisure-time activity requirements, further research needs to be carried out. Sportswear layers and their specific thermal qualities, as well as the set and air layer between materials, are all important factors in sports clothing. This research aims to examine the thermal properties of sports fabrics, and how they are affected by structure parameters and maintained with different layers. Three inner and four outer layers of fabric were used to make 12 sets of sportswear in this study. Before the combination of outer and inner layers, thermal properties were measured for each individual layer. Finally, the thermal resistance, thermal conductivity, thermal absorptivity, peak heat flow density ratio, stationary heat flow density, and water vapor permeability of bi-layered sportswear were evaluated and analyzed. The findings show that sportswear made from a 60% cotton/30% polyester/10% elastane inner layer and a 100% polyester outer layer had the maximum thermal resistance of 61.16 (×103 K·m2 W−1). This performance was followed by the sample made from a 90% polyester/10% elastane inner layer and a 100% polyester outer layer, and the sample composed of a 100% elastane inner layer and a 100% polyester outer layer, which achieved a thermal resistance value of 60.41 and 59.41 (×103 K·m2 W−1), respectively. These results can be explained by the fact that thicker textiles have a higher thermal resistance. This high-thermal-resistance sportswear fabric is appropriate for the winter season. Sportswear with a 90% polyester/10% elastane inner layer had worse water vapor resistance than sportswear with a 60% cotton/30% polyester/10% elastane and a 100% elastane layer. Therefore, these sports clothes have a higher breathability and can provide the wearers with very good comfort. According to the findings, water vapor permeability of bi-layered sportswear is influenced by geometric characteristics and material properties.
Highlights
Due to an increase in interest in the indoor–outdoor sports and outdoor leisure hobbies, there has been a considerable growth in sportswear consumption in recent years
Samples S1, S10, and S2 had a lower thermal resistance of 14.11, 12.98, and 10.56 (×10−3) (K·m2 W−1), respectively. This is because thicker fabrics contribute to greater resistance, als 2021, 14, x FOR PEER REVIEW and sportswear made from a combination of 100% elastane and 100% polyester had lower thermal conductivity as compared to sportswear made from polyamide
This research work aimed to investigate the effect of layered fabrics in sportswear garments and their maintenance of the thermal comfort of the wearer
Summary
Due to an increase in interest in the indoor–outdoor sports and outdoor leisure hobbies, there has been a considerable growth in sportswear consumption in recent years. The use of active sporting materials has increased in recent years, allowing them to serve several activities while maintaining comfort. The use of cutting-edge textile science and technology in the production of sports and leisurewear materials is advancing every day in order to meet the demands for the improvement of performance in athletic and leisure activities [2]. Many sports activities have different clothing expectations, and the requirements for sportswear change according to the weather. Low heat insulation qualities and high air permeability are expected from clothes worn in hot weather conditions to reduce heat stress. Water repellency properties are preferable to air permeability blocking in hot and rainy weather conditions [4]
