The textile and apparel industry is currently experiencing a profound transformation driven by digitalization, sustainability concerns, and the rapid advancement of artificial intelligence technologies. Traditional design and manufacturing approaches are increasingly being replaced by digital systems that enable designers and engineers to develop, evaluate, and optimize products in virtual environments before physical production. Uniform design, which requires the integration of functionality, comfort, aesthetics, ergonomics, and corporate identity, represents one of the most significant application areas of these technological developments. Modern digital tools such as Computer-Aided Design (CAD), Computer-Aided Manufacturing (CAM), digital twin technologies, three-dimensional (3D) garment simulation systems, and artificial intelligence-supported visualization platforms contribute to more efficient and sustainable design processes. Furthermore, smart textiles and wearable technologies have expanded the functional capabilities of uniforms by incorporating sensing, monitoring, and adaptive performance features. This study investigates the integration of engineering and design within the framework of digital fashion and textile technologies. In addition, a woven fabric developed for a hostess uniform using Penelope CAD software is presented as a practical example of digital textile design. The findings demonstrate that the combination of engineering-based methodologies and creative design approaches contributes significantly to sustainability, innovation, product quality, and production efficiency in contemporary textile development.

Elastane-containing fabrics are widely used in textile applications due to the comfort and flexibility they provide. Despite these advantages, various problems such as pilling, dimensional changes, surface deterioration, and elastane protrusion may occur during use and care processes, affecting both the appearance and performance of the fabric. Therefore, evaluating the structural and performance properties of elastane-containing fabrics is important for assessing their serviceability and quality. Accordingly, this study aimed to investigate the structural and performance characteristics of a plain-woven fabric composed of 90% polyester and 10% elastane. For this purpose, a series of physical, mechanical, surface, and color-related tests were conducted, including fabric weight, thickness, warp and weft density, fabric and yarn tensile strength, air permeability, pilling resistance, color measurement, laundering fastness, and rubbing fastness. In addition, test results provided by the manufacturer were incorporated into the evaluation and compared with the laboratory findings. The results indicated that the investigated fabric exhibited generally favorable performance in terms of structural properties, strength behavior, surface appearance, and color durability. No significant surface deterioration or elastane protrusion was observed during the surface evaluations, while the fastness tests demonstrated satisfactory resistance to laundering and rubbing conditions. Overall, the findings suggest that the 90% polyester / 10% elastane plain-woven fabric possesses suitable performance characteristics for its intended end-use applications.

Advanced engineering of athletic apparel requires an intricate understanding of mechanical, structural, and thermo-physiological behavior under conditions of intense activity and regular maintenance cycles. This study presents an exhaustive experimental mapping and characterization of 26 separate knitted fabric specimens manufactured from a cross-section of primary apparel materials, including natural cotton, virgin polyester (PES), recycled polyester (REC PES), and elastane (EA) blends across multiple stitch arrangements (single jersey, three-yarn fleece, mesh, rib, piqué, interlock, and spacer configurations). The experimental framework comprised the full 16-stage testing pipeline: atmospheric conditioning, fabric mass, stitch density profiling, pneumatic bursting pressure, ball burst strength, Martindale abrasion failure cycles, pilling evaluation, multi-axial extension and elastic recovery, strip-tensile breaking strength, washing dimensional shrinkage, loop spirality deformation, air permeability, vertical capillary moisture wicking, washing color fastness, dry/wet crocking fastness, perspiration fastness under acidic/alkaline media, and phenolic yellowing storage risks. The empirical findings demonstrated that while 100% cotton specimens provide exceptional initial soft touch and moisture intake, they fail core industrial durability metrics, yielding severe lengthwise washing contraction up to -13.3% and loop spirality up to 5.8%. In contrast, dense double-knit structures, notably 100% PES Interlock variants, exhibited supreme structural locking and an unprecedented ball burst resistance of 981.0 N. Recycled synthetic variants achieved technical and performance parity with virgin counterparts across all mechanical and fastness parameters. Based on this multidimensional data pool, a localized zoning structural matrix (body mapping layout) is proposed for engineered athletic jersey optimization.

This study presents an innovative approach to designing a shoe insole with enhanced durability, sustainability, and antibacterial properties. Needle-punched non-woven recycled polyester fabrics with three different GSMs (100, 200, and 300) were developed. The composite shoe insole was developed using non-woven fabric laminated with a polyurethane sheet to enhance durability. The fabrics were treated with an antibacterial finish with three different concentrations (5%, 10%, and 15%) and subjected to 5 and 10 washing cycles. The developed composites were evaluated against their relative hand value, abrasion resistance, tensile strength, antibacterial activity, and overall moisture management capability. Overall results reveal that the developed composite shoe insole is durable, sustainable, and presents no bacterial growth, demonstrating the insole’s hygienic effectiveness.

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.

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.
