Sustainability in denim refers to the practices implemented to reduce the environmental, economic and social impacts of the denim production process and these practices are divided into two as product and production process. Sustainable denim product practices include various approaches such as using environmentally friendly, organic materials and recycled denim. In the sustainable production process, there are more sustainable alternatives such as desizing with amylase enzyme, mercerization with the best available techniques, bleaching with enzyme, ozone and laser technologies, washing with natural resources and water reduction technologies. This study aims to explain the sustainable product and production process that can reduce waste, water and energy consumption, using environmentally friendly raw materials, recycling and reuse.

In this study, nanofiber structures were obtained with convenient polymers (PVA [polyvinyl alcohol] and PCL [poly o-caprolactone]) derived from the herbal extracts of olive leaves, fumitory, and terebinth plants. Optimum nanofiber structures were identified by measuring viscosity and conductivity values and performing morphological analysis, characterization, and mechanical tests of the prepared solutions. The potential use for wound healing at the most efficient level was determined as a result of antibacterial analysis of the structures obtained. APT (PVA/terebinth) and BFO (PCL/fumitory) nanofibers had the thinnest diameter range and the highest strength values. In terms of the determination of antibacterial effects, nanofiber structures of all 3 plant species proved to be effective against bacteria. The greatest effect was observed against Escherichia coli in the nanofiber structure containing olive leaves, with a zone diameter of 32 mm. In addition, APT and BFO nanofibers had the highest values of thinness and strength. In these 2 samples, using BFO against Staphylococcus aureus and APT against Candida albicans increased their areas of activity. In the literature review, no study was available about obtaining nanofibers, especially from fumitory and terebinth plants. This study aimed to increase knowledge on obtaining nanofiber structures, including various polymers derived from olive leaves, fumitory, and terebinth plants.

Denim genel tanımıyla tamamen pamuk ipliklerden üretilen çözgüsü indigo boyalı, atkı ipliği boyanmamış ham pamuk ipliğinden dokunmuş kumaştır. Orta ağırlıkta, dayanıklı, çözgü yüzeyli dimi örgüsüdür. Günümüzde moda ürün olma durumunu hiç kaybetmeyen denim giysiler; ilk olarak çeşitli meslek grupları tarafından benimsenmiş olmasına rağmen işlevsellikleri sayesinde ilerleyen moda tarihinde hemen hemen toplumların her kesimi tarafından kullanılmaya başlanmıştır. Denim; moda gibi sürekli arayış içerisinde olan bir sektörde her sezon varlığını korumaktadır. Zamansız, milliyetsiz, cinsiyetsiz bir giysi olarak denim; moda sektörü göz önüne alındığında benzersiz bir giysi olarak ayrılmaktadır. Bütün toplumlar tarafından kabul gören ve her kesimden insanın kendi tarzına ve yaşayışına göre biçimlendirebildiği bir giysi; insanların sınıflandırılması ve ayrıştırılmasına bir engel niteliğindedir. İleri dönüşüm kavramıyla tasarlanan sürdürülebilir denim ürünler yenilikçi tasarımlar ile moda dünyasındaki yeri korunacaktır. Çalışmada ileri dönüşüm adına hazırlanan denim firmalarının koleksiyon örneklerinin yanı sıra, hatalı veya yıpranmış, kullanım süreleri dolmuş ürünlerin ve atık kumaş parçalarından hazırlanan sökme dikim ve farklı aksesuarlar kullanarak yeniden tasarlanan 4 farklı denim örnekleri sunulmuştur. Bu çalışmanın amacı, toplumun her kesimi tarafından tercih edilen denimin sürdürülebilirlik kavramının günümüzdeki duyarlılığı doğrultusunda ileri dönüşüm yaklaşımı ile incelemektir.

The growing emphasis on sustainability in fashion and textile systems has renewed interest in natural dyes as both ecological colorants and expressive design tools. This study investigates a design-oriented approach to sustainable screen-printing by combining plant-based dyestuffs with conceptual pattern development and scientific performance analysis. It assumes that natural dyes can function not only as environmentally responsible alternatives to synthetic colorants but also as active design materials within contemporary textile printing. Accordingly, the study asks how dye type and fiber type influence color performance, fastness behavior, and fiber–dye interaction in screen-printed natural fabrics. Natural dyes derived from Rubia cordifolia (Rubia^®), Punica granatum peel (Mallow^®), and Morus alba leaves (Leafy Green^®) were applied to 100% cotton, linen, and silk fabrics through an environmentally responsible screen-printing process. A garlic-inspired motif was developed to support the study’s visual and conceptual framework by representing circularity, low-impact agriculture, and cultural sustainability. Colorimetric properties (L*, a*, b*, K/S, ΔE) were measured by spectrophotometric analysis, while washing and rubbing fastness were evaluated according to international standards. FTIR spectroscopy was used to examine fiber–dye interaction mechanisms, and statistical significance was tested through two-way ANOVA. The findings show that fabric type is the dominant factor affecting color performance, with cotton exhibiting the highest color strength due to its cellulose-rich and hydroxyl-dense structure. Rubia^® produced the darkest and most saturated tones, whereas Mallow^® yielded lighter pastel-like shades. FTIR results indicated that dye fixation occurred primarily through non-covalent interactions, explaining the balance between aesthetic richness and moderate fastness. The study offers a replicable model for environmentally responsible, design-oriented textile production that integrates material innovation with cultural and visual narratives.

Purpose: As a result of referee evaluation, the subject scope of the article has been expanded. Previously, only polycaprolactone (PCL) loaded with peppermint extract had been studied. As a result of peer review, nanostructure production was made with peppermint-loaded polylactic acid (PLA). Literature information about PLA polymer has been added to the Introduction section. Additionally, to analyze the presence of peppermint extract in Fourier transform infrared (FTIR) measurements, a comparison was made with 100% PCL, 100% PLA and 100% peppermint extract. In order to observe the effect of polymer type, evaluations were made between the produced peppermint-loaded nanostructures containing two different polymers. Mechanical, structural and morphological properties of the produced nanostructures were measured. The main purpose of the study is to analyze and evaluate peppermint-loaded nanostructures on different polymers.Design/methodology/approach: Nanofiber structures were produced by the electrospinning process due to their attractive properties such as low cost, flexibility, integrability and high efficiency. The production parameters of the nanofiber structure produced by the electrospinning process, mechanical measurements, fiber morphologies with scanning electron microscope (SEM) and structural characterization with FTIR measurement were analyzed, and its potential in possible usage areas was interpreted.Findings: In this study, the production of nanostructures containing peppermint extract with PCL and PLA polymers, which are various biodegradable and biocompatible polymeric materials, was successfully achieved. In the studies carried out, nanofiber structures with positive properties such as low cost, easy accessibility, flexibility, integrability and sustainability were produced. When the two nanofiber structures produced were compared, it was observed that the peppermint extract nanofiber structure containing PCL provided better morphological and mechanical properties, such as higher strength, thinner fibers' diameter and a smooth and homogeneous surface, compared to the peppermint core nanofiber structure containing PLA. It has been observed that PCL polymer is more advantageous in obtaining nanofibers under the same environmental conditions and the same parameters. The addition of peppermint extract caused an approximately 25% loss in strength in nanostructures containing PCL polymer compared to nanostructures containing 100% PCL. The strength loss in PLA nanostructures containing peppermint extract is approximately 90% compared to nanostructures containing 100% PLA. This situation is associated with the regular arrangement of nanostructures containing PCL. In conclusion, incorporating peppermint extract into the nanofiber structures fabrication process offers several benefits, including enhanced antimicrobial properties and potential bioactive effects.Originality/value: In the study, a uniform and suitable-for-use nanofiber structure with a smooth and partially beaded surface was obtained by an electrospinning method using peppermint extract and PCL and PLA polymers. Morphological evaluation was made with SEM images of the obtained nanofiber structure, and the presence of peppermint extract in the nanofiber structure was determined by the FTIR analysis. In the mechanical analysis, a decrease was observed in the elongation at break and tensile strength values of nanostructures loaded with mint extract, but this decrease did not prevent the production and use of the nanofiber structure.
