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

Sport clothes are mainly produced from polyester yarn because of good wicking behaviour and moisture transfer properties of this yarn. In this paper, thermophysiological comfort properties of ring staple polyester, textured polyester and special type of polyester knitted fabrics, which is described as good moisture management property yarn by producer, were investigated. For this reason, thermal resistance, thermal absorptivity, thermal conductivity, air permeability and moisture managent properties of fabrics were tested. The results showed that, textured polyester yarn knitted fabrics were showed the highest air permeability values than moisture management polyester in same yarn count and knit structure. Lower filament number fabrics shows higher thermal resistance values in same yarn count of fabrics. Moisture management polyester knitted fabric (Type 10) showed the highest top absorption and one way transport index value. Also moisture management polyester yarn knitted fabrics, except Type 7, were showed very good moisture management properties according to MMT grading scale. This is most probably cross-sectional shape of this fiber.

Abstract. Denim jeans are preferred because of durability and easy washing properties. Nowadays the expectations of consumers from denim fabrics are changed towards design and comfort properties. Fort this reason, thermal and moisture comfort properties of denim fabrics should be examined. This paper aims to investigate thermal, air permeability and moisture management properties of 3/1 Z twill weaved denim fabrics. These fabrics are produced mainly from cotton with different yarn count and cover factors are close to each other.

In this study, it is aimed to change the loop length of knitted fabrics with a mesh structure and to investigate the effect of loop length differences on thermal and moisture transmission properties. For this purpose, six fabrics with different loop lengths were produced in two different knittings and yarn types. Thermal conductivity, thermal absorptivity, thermal resistance, air permeability and moisture management properties of these fabrics were measured according to standard test methods. The results showed that as the yarn gets finer and loop length increases, the air permeability values will increase. It was observed that as the loop length increase, the overall moisture management capacity (OMMC) and thermal absorptivity of the fabrics will decrease. The thermal resistance values of two ply textured polyester mesh knitted fabrics decreased with increasing density and the highest loop length two ply textured polyester mesh knitted fabric showed the highest thermal resistance value.

Özet: Askeri üniforma olarak kullanılan giysiler sürekli ve uzun süre giyilmeleri ile diğer giysilerden farklılık göstermektedir. Bu tür giysilerin içinde ısı, nem ve hava hareketleri termofizyolojik konforu sağlayan en önemli parametrelerdir. Kullanıcıların konforlu hissedebilmesi için giysilerin vücuttan çıkan su buharının geçişine izin vermesi gerekir. Bu çalışmada kışlık askeri üniforma olarak kullanılan yün/polyester karışımlı kumaşların nem iletim özellikleri MMT test cihazıyla incelenmiştir. Bu amaçla farklı yün/polyester karışım oranı ve örgü yapısında olan kumaşların ıslanma zamanı, emilim oranı, yayılma hızı, kümülatif tek yönlü transfer indeksi ve genel nem yönetimi özellikleri incelenmiştir. Ayrıca nem transferi yönünden uygun kumaş yapısı belirlenmeye çalışılmıştır.Anahtar Kelimeler: Yün/polyester, askeri giysiler, nem konforu Investigating Moisture Management Properties of Weaving Military ClothesAbstract: Clothes which are used as military clothes are different from the other clothes, because they are worn continuously and long time. Heat, humidity and air movements are very important for these clothes because these parameters effect the thermophysiological comfort properties of clothes. These clothes must allow the passage of water vapour from the body of the garment to feel comfortable to wearer. In this study, moisture management properties of different blends of wool/polyester fabrics which are used in winter military clothes were examined with MMT test device. For this aim, wetting time, absorption rate, spreading speed, accumulative one way transfer index and overall moisture management capacity of fabrics, which have different wool/polyester blend ratio and weave pattern, were investigated. Also fabric pattern which are more appropriate for moisture transfer, were determined.
