This study aims to investigate the importance of designing footwear according to age-specific needs, from infancy to adolescence. The research takes into account various factors like physiology, psychology, and activity levels, and emphasizes the need to tailor footwear to meet the unique requirements of each age group. The study explores the crucial role of appropriate footwear in promoting foot health and overall well-being. It delves into the specific design requirements for different age groups, such as infants, toddlers, preschoolers, school-age children, and adolescents. Key considerations include flexibility, support, durability, comfort, and style preferences, which evolve alongside developmental milestones and lifestyle changes. By analyzing existing literature and empirical findings, this paper provides a comprehensive analysis of age-specific footwear design principles. The study aims to offer valuable insights for industry professionals and researchers, leading to the development of age-appropriate footwear solutions that enhance both comfort and performance while safeguarding the health of younger demographics. The final fit of the developed shoes was tested to determine the appropriate size for the respective age groups. It was found that shoe size cannot be determined with only one measurement.

Historically, cotton has been regarded as a highly sustainable material; however, thorough research indicates otherwise. The increasing levels of pollution and the need to address climate change have led towards a global search for sustainable alternatives. Plants with comparable chemical compositions, such as hemp, are attracting growing attention. The cultivation of hemp can be done with sustainable methods, thereby making it a viable alternative to cotton. This study investigates the mechanical, physical, and dyeing properties of 100% wet-spun hemp yarn in its natural and bleached state with the objective of incorporating its use in both technical and traditional textiles. Although significant academic literature is available on the properties of cotton, there is a noticeable lack of literature based on wet-spun hemp. This research suggests that the bleaching process positively affects wet-spun hemp yarn, thus making it suitable for use by the textile industries in various applications.

Geleneksel denim üretiminde, sürdürülebilirlik kavramı kapsamında birçok çalışma yapılmış ve üretim prosesleri ve ham malzemelerde önemli gelişmeler yaşanmıştır. Sürdürülebilir kalkınma hedefleri doğrultusunda farklı programların desteğinde sektörde hızlı bir değişim ve gelişim yaşanmaktadır. Çeşitli sertifikalandırma ve denetleme süreçleri ile sürdürülebilirliğin şeffaflığı sağlanmaya çalışılmaktadır. Bu derleme çalışmasında, sektörde kullanılan alternatif sürdürülebilir elyaf türleri, boyama ve terbiyedeki son gelişmeler ve geri dönüşüm konuları incelenmiştir. Döngüsel ekonomi temellerinde, gelişen teknolojiyle birlikte denim sektöründeki karbon ayak izinden ve metaverse evreniyle olan ilişkisinden de bahsedilmiştir.

As the global population grows, there is an increasing demand for food, requiring sustainable farming methods to increase agricultural productivity. Soil covers and mulches used in agriculture are mostly made of synthetic materials derived from petrochemicals, which pose various problems such as soil contamination and long-term insolubility. This study aims to use Ulva Lactuca algae as a sustainable raw material for soil covers, as it contains vitamins and minerals that the soil needs. As seawater acidity increases, the population of this algae is also increasing, creating the opportunity to use it in agriculture. The product is expected to retain moisture and reduce water consumption and high temperatures. In addition, hurds obtained from industrial hemp waste are used due to their high-water retention potential. The study combined Ulva lactuca algae from the Marmara region and hemp strings from Narlı and Vezir seeds to create various composites with different structures. Basic tests were conducted to determine the mechanical and physical properties of the products. The goal is to increase soil organic matter by using these materials as fertilizer after their use as soil covers.

With the growing perception of sustainability and vintage fashion trend, the textile industry is taking steps toward change and innovation with the benefit of recent technological development. Using traditional fabrics to modernize from the past to today's technology is one of the most popular research and design topics. Fashion shows real proof that history repeats itself over and over again. Along with the modern developments increasing variety of fibers also helps to develop innovative product possibilities. Seersucker is not a common type of fabric. Seersucker actually refers to a style/pattern/texture that produces a puckering effect on the surface of the fabric with the textures smooth and coarse. In this study, first, a brief historical background of the seersucker fabrics is explained. The most used seersucker fabric types are determined to design and produce during this study. The selected patterns of seersucker fabrics with different fiber combinations were produced according to the common strip model, and their technical properties were tested and analyzed. 5 different types of fabrics are tested in terms of their structural properties, color fastness to water, color fastness to perspiration, etc.

Tarımsal faaliyetler, ülke ekonomisi ve kalkınması için önemlidir ancak çevresel yan etkileri oldukça fazladır. Bu zararı en aza indirmek için sürdürülebilir, sorumlu üretim ve tüketim desteklenmelidir. Tarım sektöründe mevcut olarak kullanılan toprak örtüleri ve malçlar petrokimya esaslı sentetik malzemelerden yapılmaktadır. Uzun yıllar doğada çözünmeden var olmaları hem doğaya hem de canlılara zarar vermektedir. Bu çalışmada Narlı ve Vezir tohumlarıyla elde edilen kenevir, muz atıklarından gübre üretilirken açığa çıkan kısa elyaf ve taşıyıcı lif olarak Polilaktik Asit (PLA) biyobozunur lif harmanları ile toprak örtüsü elde edilmiştir. Geliştirilen toprak örtüsünün, toprak nemini optimum seviyelerde tutmaya yardımcı, kuru ağırlığının ortalama 5 katı kadar su veya nemi emme kapasitesinden dolayı geliştirilen kumaşların farklı iklim tiplerinde kullanımı amaçlanmaktadır. Teknik nonwoven yapının yabani ot büyümesi gibi problemlere de çözüm sunması hedeflenmiştir. Belirtilen özellikler eko-ambiyansı bozmadan sağlanırken biyolojik olarak parçalanıp toprağa karışması sonucu sürdürülebilirlik sağlanır. Optimum yapının oluşturulması için farklı hammadde oranlarında çeşitli yapı tasarım denemeleri yapılarak ilgili temel testler uygulanmıştır.
