Slub yarns, whose characteristic feature is planned thick regions in the yarn diameter, have an important place among the fancy yarns that have an increasing usage in clothing and home textile products. These yarns, used in woven and knitted fabrics, create unique visual and textural effects compared to conventional yarns, giving yarn manufacturers a competitive advantage. In this study, the performance properties of knitted fabrics produced from slub yarns were examined depending on slub parameters such as slub thickness, slub frequency, slub length, yarn twist coefficient and slub population. The results showed that slub frequency, slub thickness, and twist coefficient significantly affect the air permeability of the fabrics Additionally, the study found that slub frequency and slub thickness are important parameters for abrasion resistance, while yarn twist coefficient is crucial for bursting strength. In terms of fabric pilling property, increasing slub thickness, length, and frequency were found to increase fabric pilling tendency.
Modelling thermal resistance of woven fabrics in wet state
(Inst Natl Cercetare-Dezvoltare Textile Pielarie-Bucuresti, 2025) Kanat, Zehra Evrim
In this study, a simple mathematical model based on conductive heat transfer is suggested for predicting the thermal resistance of wet woven fabric. For this purpose, cellulosic fabrics produced in two different weave types with different moisture content were investigated. Fabric is considered a system of a porous structure consisting of fibre, air and if present, water. The thermal resistance of fabric was calculated according to the proportion of these components. It was considered that the water's location could have changed the resistance values. The assumption was the capillary water was arranged serially with fibres and air when it was located in the yarns, and it was arranged parallel with the air when it was located between the yarns. Calculated values were compared with the measurement values obtained from ALAMBETA. When the results were evaluated, the obtained values were quite good except for the absolute dry fabric. Serial arrangement of fibre and air was better fitted for dry fabric. So, it is thought that the air acts as a single block in absolute dry fabrics. Additionally, for comparison, Maxwell-Eucken2 (ME-2) was also used. The new model's R-2 value is a little higher than the other model as 0.9017. Furthermore, MSSD and MSAD values were 0.0000013 and 0.0007878 for this model, respectively. As a result of the study, it can be said that the suggested model is useful for predicting the thermal resistance of woven fabrics with different moisture content. Besides this, analyses of fabric porosity can be useful to manage the thermal resistance of wet fabrics.
Environmental impact, economic and carbon footprint assessment of end-of-life PVC flex banners and its potential upcycling opportunities in the fashion industry
(Elsevier B.V., 2025) Saatçioğlu, Kenan; Venkatraman, Prabhuraj D.
This article employs life cycle assessment (LCA) using openLCA software to compare the environmental and economic indicators of upcycled fashion accessories made from end-of-life polyvinyl chloride (PVC) flex banners with those made from conventional materials like nylon and polyester. Six bags were designed, produced from end-of-life PVC flex banners, and compared to nylon and polyester fabric bags. Data related to the manufacturing process of these bags, including material usage, transport, and production, were analysed for comparison. The LCA results revealed that upcycled bags made from end-of-life PVC flex banners are more environmentally friendly than their nylon and polyester counterparts. Out of the 16 environmental impact categories analysed in the study, U-PVC bags were shown to have a lower impact in 12 categories: 1) fossil depletion, 2) freshwater ecotoxicity, 3) freshwater eutrophication, 4) marine ecotoxicity, 5) marine eutrophication, 6) ozone depletion, 7) particulate matter formation, 8) photochemical oxidant formation, 9) terrestrial acidification, 10) terrestrial ecotoxicity, 11) urban land occupation, and 12) water depletion. Moreover, the carbon footprint of U-PVC bags was 574.89 kg CO2 eq, which is lower than the carbon footprints of C-PA bags at 612.56 kg CO2 eq and C-PES bags at 609.76 kg CO2 eq. Additionally, the average manufacturing cost of U-PVC bags was £49.86, compared to £66.80 for C-PA bags and £67.09 for C-PES bags. This indicates that U-PVC bags are not only more environmentally sustainable but also more economical compared to C-PA and C-PES bags. Our research highlights the potential to upcycle end-of-life PVC flex banners into shoulder backpack bags, demonstrating the viability of PVC upcycling to reduce environmental impact. © 2025 The Authors

Fancy Yarns: Alternatives to Comfort-Enhanced Fabrics
(Nova Science Publishers, Inc., 2024) Kanat, Zehra Evrim
Fancy yarns, which contain various effects in terms of color and/or structure, attract the attention of textile and fashion designers with their aesthetic appearance. Designers use these surface effects, created by some planned irregularities in the yarn, as a design element. Moreover, the use of fancy yarn also enables the economical production of original designs. With the developments in recent years, fancy yarn types have become very diverse, and it is possible to talk about the limitless effects that can be obtained by using both the type and parameter of fancy yarns as variables. In addition to the design differences fancy yarns create in the appearance of the fabric, they also change the surface characteristics of the fabric, sensory and thermophysiological comfort properties. Research has been carried out to examine the effects of raw materials used in yarn production, fancy yarn production parameters, and fabric production parameters on the dimensional, physical, appearance, and comfort properties of the fabric. In this section, fancy yarn structures are defined and classified, and studies on the comfort properties of fabrics produced using fancy yarn are mentioned.
ÇANAKKALE KARINCALIK KÖYÜ TAHTACI TÜRKMEN KADIN GİYİM KUŞAMI VE DEĞİŞİMİ ÜZERİNE BİR ANALİZ
(Ankara Haci Bayram Veli University, 2024) Koca, Emine; Polat Turhan, Gülşah
Yüzyıllar boyunca gelenekli yaşam biçimlerinin sürdürüldüğü Anadolu’da, toplulukların kendi kültür ve öğretileriyle geliştirip yaşattıkları gelenekselleşmiş somut veya somut olmayan birçok öğe bulunmaktadır. Küreselleşme ve teknolojik gelişmelerle değişen yaşam tarzlarıyla birlikte bu öğelerin değişime uğrayarak yozlaşması ve yok olma tehdidi altında olduğu gündemde olan ve sıklıkla tartışılan konulardır. Somut/maddi kültür miraslarımız arasında yer alan giyim-kuşam ürünlerinin de bu kapsamda ele alınarak özgün özelliklerinin belgelenmesi ile yozlaşmanın önüne geçilebileceği gibi, geleceğe aktarılarak kültürel bilincin güçlendirilmesine katkı sağlanacaktır. Bu çalışmada, Çanakkale Karıncalık Köyü Tahtacı Türkmenlerine ait geleneksel kadın giyim kuşamının biçimsel özelliklerinin belirlenmesi amaçlanmıştır. Yapılan saha çalışmasında araştırmacılar tarafından doğrudan gözlem yapılmış, yapılandırılmış görüşme formu ile kaynak kişilerle görüşülmüş ve Tahtacı Türkmen giyim kuşamına ilişkin veriler tespit edilmiş ve ulaşılan 12 adet orijinal giysi araştırma kapsamına alınmıştır. . Bedene ve başa giyilenler başlığı altında gruplandırılarak sunulan giysilerin biçimsel çizimleri yapılmış ve her giysi parçası alan sistematiğine göre biçim, malzeme, renk ve süsleme özellikleri açısından incelenerek kaynak kişilerden elde edilen bilgilerle desteklenerek açıklanmış ve değişime uğrama durumları yorumlanmıştır. Araştırma sonuçlarına göre, günümüzde bu giysilerin özel günlerde nostaljik yada kültürel amaçlı kullanıldığı, giysi parçalarının Türk halk giyiminde kadınların kullandıkları katlı giyim biçimini oluşturan ana parçalar olduğu, kesim özellikleri ile Türk halk giyiminin temel karakteristiklerini yansıttıkları görülmüştür. Günümüzde üretilen giysilerin değişiminde kişilerin isteklerinin etkili olduğu ve değişikliklerin yöreye özgü bir özellikmiş gibi kabul görerek yozlaşmanın devam ettiği belirlenmiştir.
The environmental impact of end-of-life PVC flex banners and its potential upcycling opportunities
(Elsevier B.V., 2024) Saatçioğlu, Kenan; Venkatraman, Prabhuraj D.
PVC is used as a raw material for many products, especially in the production of flex banners. PVC flex banners used for advertising or marketing purposes have a short-term use [average up to 45 days]. PVC flex banners are usually annihilated, piled in landfills, incinerated, or buried under the soil, thus causing severe damage to the environment. This systematic literature review highlights the research carried out on this topic over the last two decades and discusses industry practices in producing PVC flex banners, the environmental impact of PVC flex banners due to annihilation, and reuse and recycling methods for PVC flex banners. One of these opportunities is upcycling, which is an important part of the reuse strategy. These flex banners can be reused in the fashion industry as upcycled products [high-value functional and aesthetic products] and accessories through zero-waste fashion production processes [especially used in pattern designing and cutting stages]. These include primarily bags and luggage, apparel, footwear, worker uniforms, and accessory upcycle products. Based on findings from the systematic review, it recommends a conceptual framework that emphasises the impact of end-of-life PVC flex banners and offers ways for reuse that avoid piling in landfills, incineration, and burying these wastes under the soil, reducing the impact on the environment. The studies suggesting the production of upcycling products from end-of-life PVC flex banners by the zero-waste fashion production process have not been sufficiently researched and reported, and they are a novel method of reusing resources.
