In order to determine the effect of raw material, weave type and tightness on liquid absorption and transmission which is an important factor in the perception of people’s clothing comfort, knitted fabrics made of cotton, viscose and polyester yarns, which had single jersey, 1 × 1 rib and single pique weave type, had three different tightness as tight, medium and loose, were produced. Moisture management tester (MMT) was used for multi-dimensional liquid transport of the fabrics produced. As a result of the study, it is observed that polyester fabrics had higher OMMC values than those of cellulosic-based fabrics. Regarding the effect of tightness, liquid transport has decreased with increasing tightness in general. Weave types examined in this study, were not as strong as raw materials and tightness and did not have such a significant effect.

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.

In this study, fabrics with different plain, tuck and float stitch combinations in three different tightness levels as tight, medium and loose are produced from combed ring spun cotton yarn. It is aimed at determining the effect of fabric structure on liquid absorption, transport and permeability properties, which are important factors in the people’s perception of wear comfort. The air permeability, wicking ability and moisture management measurements of the produced fabrics are made. It is determined that the increase in the fabric tightness decreases the air permeability and increases the wicking ability especially in 60 min measurements. The fabric tightness has also different effects on different knitting types in terms of moisture management properties. It is observed that structures with float stitches show high wicking ability and moisture management properties in terms of plain, tuck and float stitches combinations.

Recycled fibre obtained from fabric scrap wastes is characterized by its low quality properties in terms of inhomogeneous fibre type and non-uniformly distributed short fibre lengths, both of which negatively influences the production process and the quality of the recycled yarns made from it. One of the common ways to utilize recycled fibre in yarn production is to blend it with virgin fibres. In this research article, the quality properties of the open-end spun recycled yarns produced in different material and spinning parameters from blends of recycled fabric scrap wastes and virgin polyester fibres are investigated. As material and spinning parameters, yarn count, blend ratio, waste type, waste origin, twist coefficient and rotor diameter are selected and their effects on the quality properties of the recycled yarns are evaluated through statistical methods. Statistical results reveal that especially blend ratio, yarn count and twist coefficient significantly affect the quality properties. In general, incorporation of virgin polyester fibre to recycled fibre tends to bring about improvement in yarn quality.

Kenevir, yenilenebilir ve sürdürülebilir karakterde ve çok amaçlı bir ürün olması sebebiyle bilimsel, sektörel ve ekonomik yönlerden günden güne önem kazanan bir malzeme olmaktadır. Esasında kenevir bitkisi insanlık tarihi boyunca kullanılmış en eski lif bitkilerinden birisidir. Buna karşın kenevir üretimi, esrar eldesinde kullanılabilmesi ve zamanla sentetik liflerin yaygınlaşması sebebiyle küresel anlamda gerilemiş ve ülkemizde ise bitme noktasına gelmiştir. Tekstil, ilaç, kâğıt, biyoyakıt, kozmetik ve otomotiv gibi birçok farklı sektörde oldukça geniş bir kullanım alanı olan kenevir, petrol ve petrokimyanın kullanıldığı her alanda alternatif olan, üstün özelliklere sahip bir bitkidir. Ayrıca kenevirin, ekolojik özellikleri sebebiyle de sürdürülebilirliğe fayda sağlaması beklenmektedir. Türkiye’deki iklim şartları kenevir yetiştirmeye elverişli olduğu için yapılacak yatırımların geri dönüşünün hızlı bir şekilde gerçekleşmesi ön görülmektedir. Bu çalışmada kenevirle ilgili güncel çalışmalar araştırılmış ve öne çıkan yanları değerlendirilerek çevresel ve ekonomik anlamda ülkemiz ve dünya geleceği açısından katkılarından bahsedilmiştir.
