The aim of this study is comparatively examine the carbon footprints of “knitted” and “woven” bathrobes, sheets, piques on a production and machine basis. Bathrobes, sheets, piques made of “woven fabric” and “knitted fabric” are manufactured by passing through stages of weaving, dyeing plant, cutting, sewing and packaging. However, CO2 emission is released during manufacture. In this study, a textile company located in Denizli city of Türkiye is chosen as a case study. As a result, when woven bathrobes, knitted bathrobes, woven sheet, knitted sheet, woven pique, knitted pique produce 1.46 kg, 1.41 kg, 1.56 kg, 1.28 kg, 1.53 kg, 1.43 kg of carbon emissions are released for the production of 1 kg of fabric, respectively. As can be seen, the highest exports are in bed sheets and the highest carbon footprint is released in bed sheet production.
The cutting stock problem (CSP) is a critical optimization problem in the textile industry, where minimizing fabric waste and overproduction is essential for cost-effective production. This study proposes a methodology integrating a pattern generation algorithm and a multi-objective goal programming model for pattern selection. The proposed pattern generation algorithm creates guillotine cuts using a three-stage procedure, ensuring ease of applicability in manual production processes. The pattern selection model considers both fabric remnants and overproduction as waste, offering a comprehensive framework for the textile manufacturers. The multi-objective model is solved using both preemptive and weighted goal programming approaches, offering flexibility for aligning with varying order management strategies. A case study validates the effectiveness of the model in reducing overall waste while addressing key constraints in textile manufacturing. Compared to existing methods, the proposed approach enhances practicality and adaptability making it suitable for real-world textile production environments, particularly where manual cutting is employed.
The need for high-performance textiles with superior mechanical strength necessitates the analysis of hybrid yarn structures. This study investigates the maximum force at break (MFB) of multicomponent hybrid yarn. The hybrid yarn, comprising three components where ultra-high molecular weight polyethylene (UHMWPE) as outermost sheath, stainless steel (SS) in core, a polyester as middle layer. Key parameters—UHMWPE linear density, SS (µm), and twist per meter (TPM)—were analyzed for their impact on MFB. ANOVA confirmed the significance of UHMWPE and TPM, with 200 TPM, 400 Den UHMWPE, and 50 µm SS achieving an MFB of ~85-90 N. The quadratic regression model provided an excellent fit (R² = 0.9966, adjusted R² = 0.9904, predicted R² = 0.9454) and predictive accuracy demonstrated by an average of 2.25% relative error. These findings offer actionable insights for enhancing the performance of hybrid yarns in cut, slash, stab and impact resistant applications.
It is well established that fiber type and fabric structure are key factors of thermo-physiological comfort. In this study, single-layer, double-faced (plated) knitted fabrics were engineered to enhance thermal comfort by promoting rapid moisture transfer, making them especially suitable for garments used during intensive activities and sports. To achieve this, ten plated fabric samples were knitted using four different fiber materials under identical machine settings. We measured air permeability, water vapor permeability, moisture transfer capacity, thermal resistance, weight, thickness, and stitch density according to relevant standards. The collected data were analysed through statistical and comparative methods. The results revealed that all samples generally exhibited high air and relative water vapor permeability, adequate thermal resistance, and effective moisture management. Moreover, fabrics with different yarns on the inner and outer surfaces showed significantly improved one‑way moisture transport performance.
Textile recycling is becoming an increasingly important sustainable approach to minimizing environmental load in production processes, reducing chemical, energy, and water consumption. In this study, the effects of recycled fiber from different sources, different recycled fiber ratios, and the use of recycled fibers in blended fibers on the mechanical properties of woven fabrics were examined. In addition, reactive dyeing and different printing processes (reactive - pigment) were applied to the fabrics, and the effects of these processes were also examined. Tensile and tear strength, abrasion, and pilling resistance and strength properties after multi-cycle washing were performed. The results showed that using 15% recycled cotton fiber in the fabrics and recycled fabrics produced from weaving unit waste performed better in terms of mechanical properties. Furthermore, it has been shown that fabrics containing recycled cotton adequately retain their mechanical properties and that it is possible to increase the use of recycled fibers.
