“…This supports previous studies that the thermal resistance of the fabrics depends on the thickness of fabrics. 19 The fabric density was obtained by dividing the weight by the thickness. The fabric samples were produced from polyester yarn, so the density of the fabrics helped us to understand the effect of the knit type and yarn count on the thermal properties of the fabrics, in conjunction with the weight and the thickness.…”

In this paper, we measured the thermal and moisture management properties of six different types of polyester knitted fabrics that are used in the production of summer cycling clothes. The test samples were selected from the most commonly used fabric structures according to the results of a survey on a cycling team in Bursa. The fabrics were compared to determine which fabrics were more convenient for cyclists. Thus, we carried out objective fabric tests to determine the thermal resistance, water vapor resistance, air permeability and moisture management properties. Good moisture comfort, low water vapor resistance and good moisture management properties were preferred, especially in summer clothes. In the final evaluations of the fabrics, it was found that Type 6 Warp knitted raschel fabric was more convenient for summer cycling clothing because of its good air permeability, low thermal resistance, low water vapor resistance and good moisture management properties.With increased emphasis on healthy living and saving time, men and women are paying more and more attention to sporting activities. People want to spend their leisure time in sport halls, gymnasiums or engaged in other sporting activities. Cycling is one of the most popular sports. Cycling can be performed in many different weather conditions; thus, the expectations that people have from athletic apparel has increased. Athletic apparel must prevent excessive heat loss in cold weather and enable the release of sweat from the surface of the skin in hot weather. 1 Thermal resistance, air permeability, water vapor permeability and liquid water permeability have been suggested as critical properties for the thermal comfort of the clothed body. 2 Any level of physical activity will produce the need to release excessive heat to maintain a stable body temperature. 3 Heat release from the skin can be divided into dry heat loss and evaporation. 4 There are various test methods for measuring the mass diffusivity of fiber assemblies. 5 The sweating hot plate instrument best simulates the conditions under which the clothing is worn, proving test results that relate to the thermophysiological responses of people wearing clothes. 6The fabric liquid moisture transport properties in multi-dimensions can describe the moisture management properties and the influence of the human perception of moisture and comfort. 7 To evaluate the moisture management capacity of porous polymeric materials, such as fabrics, a new test method and an instrument called the moisture management tester (MMT) have been developed. 8 Over the years, many studies on clothing comfort have been carried out. Fanger showed that the conditions for thermal comfort are dependent on the activity level, the thermal resistance of the clothing, the air temperature, the mean radiant temperature, the relative air velocity and the vapor pressure of the ambient air. 9 D'Silva et al. demonstrated that polyester-fiber fabrics

“…Although cotton clothes are good in absorbing perspiration of the wearer, they are pretty poor in transporting that from the wearer's skin side to the outer side for quick evaporation. This is mainly because of the presence of hydrogen bonding sites in the fiber that restrict the transport of moisture horizontally on fabric surface as well as vertically away from the skin (Onofrei et al 2011).…”

Garments made from cotton fabrics can readily absorb perspiration during strenuous activities but give poor performance in terms of wicking and evaporation of the perspiration, resulting in wet sticky feeling to the wearer. The aim of this study was to investigate the effect of design and method of creating wicking channels on the moisture management and air permeability of cotton fabrics. The fabric specimens were printed with hydrophobic fluorocarbon finish using four different print designs, each with two different types of printing squeegees. It was found that both the type of print design and squeegee type significantly affect most of the moisture management properties of the fabric. The study concluded that by selecting a suitable print design and squeegee type, moisture management capability of cotton fabrics can be significantly improved without sacrificing the fabric air permeability.

“…It was seen in the results that the fabrics with interlock knitting type had the highest thermal resistance value, and that singlejersey fabrics had the highest water vapor and air permeability values. Onofrei, Rocha, and Catarino (2011) examined the thermal and moisture transfer properties of knitted fabrics in different knitting types produced from Coolmax and Outlast fibers. According to the results, it was seen that the liquid moisture transport capacity of fabrics was determined by the fabric structure, the drying ability was determined by the raw material; the Outlast fabrics had lower thermal resistance values compared to Coolmax fabrics.…”

Thermal comfort is one of the most important components of comfort which shows physiological, psychological, and physical harmony between human body and environment. The heat and moisture transfer capacity of fabric from skin to environment affects the thermal comfort of garments. The transfer capacity depends on the characteristic features of raw materials and fabric structural properties. In this study, it is aimed to determine the advantages of knitted fabric types, taking into account the environmental condition and activity level by measuring the thermal comfort properties such as air permeability, wicking, moisture management, thermal and water vapor resistances. Two knitted structures composed of tuck and float combinations and six raw materials were chosen for the fabrics produced. According to the measurement results, the polyester and cotton/Coolmax fabrics with float stitches have had good liquid moisture transport properties. Besides, high air permeability and low water vapor resistance have been obtained in viscose and Tencel LF fabrics with tuck stitches. On the basis of the results obtained in this investigation, and taking into consideration thermal behavior of human body, four women's and five men's T-shirts are designed. These T-shirt designs may be helpful for further approaches on the optimization of thermal comfort for sports activities in hot environment.
