In this study, a cost-effective and sustainable approach was developed to fabricate three-dimensional magnetic carbon fibers derived from natural loofah sponge. The loofah precursor was pretreated with phosphoric acid and subsequently carbonized, while magnetic properties were introduced through the thermal decomposition of cobalt chloride salt, leading to the formation of cobalt and cobalt oxide nanoparticles. Thermal treatment was carried out at 500 °C, 650 °C, and 800 °C, and the equilibrium oil sorption capacities of the resulting samples were found to be 32.18 ± 0.21 g/g, 30.20 ± 0.32 g/g, and 20.33 ± 0.39 g/g, respectively. The results demonstrate that the produced carbon fibers not only exhibit high oil sorption efficiency but also enable rapid and facile recovery due to their magnetic nature. Overall, this work presents a simple and low-cost strategy for converting loofah waste into advanced magnetic carbon adsorbents with promising applications in oil spill remediation and environmental protection.Oil spills and oily pollutants in aquatic environments represent a serious global environmental challenge.

The research findings provide a basis for developing a global carpet classification system, which could lead to the establishment of a quantitative valuation index and an integrated certification system. In this regard, a comprehensive database of 99 museum carpet samples was collected, containing 12 parameters related to structure, design, and raw materials. To achieve these objectives, K-means clustering algorithm with Euclidean distance and k=3 was employed based on the elbow method, and the samples were divided into three homogeneous clusters based on knot density, material composition, and pile material. The main innovation of this research lies in converting traditional and subjective criteria into objective indices, enabling direct comparison of new carpets with historical samples. This system not only increases valuation accuracy but can also lead to pricing transparency, development of global markets, greater buyer confidence, the possibility for buyers to purchase according to their taste and interest in carpets from a specific region, and providing a basis for trust in sellers' opinions.</span><span>This study was conducted with the aim of designing an objective classification system for authentic Iranian carpets.

This topic is of significant importance due to the increase in employee motivation in textile production sectors and the reduction of stress and its impact on personnel burnout. The present research is applied in terms of its objective and correlational in terms of its research method. Data were collected using a survey method through simple random sampling from 425 personnel involved in the melt spinning process in textile factories. The data collection instruments included the Maslach and Jackson standardized burnout questionnaire, the Minnesota standardized job satisfaction questionnaire, and a researcher-designed performance strategy questionnaire based on previous studies. To describe the data, the validity and reliability of the questionnaires were first assessed using PLS software. Descriptive statistics were then calculated, and for analyzing the relationships between variables, exploratory factor analysis was conducted using SPSS27, followed by confirmatory factor analysis using PLS software. The results of the analyses showed a high correlation between the latent variables of job burnout, motivation, job satisfaction, and performance strategies (as second-order factors in factor analysis) with their respective latent sub-factors. Furthermore, the effects between the three factors were confirmed based on their significance values, which were all below 0.05. In summary, the results indicated that performance strategies in textile production processes, particularly in synthetic fiber production, have a significant impact on employees’ job satisfaction, motivation, and burnout. Therefore, it is essential to shift from traditional management approaches to modern performance strategy methods.The aim of this study is to propose a model for examining the mediating effect of performance strategies in the relationship between job burnout, motivation, and job satisfaction in textile processes, particularly in the production of synthetic fibers.

To achieve this aim, the Multi-Grounded Theory (MGT) approach was employed. In the first phase, a meta-synthesis of 59 scholarly articles published between 2003 and 2025 was conducted to identify and integrate the key components of technology transfer. Subsequently, empirical data were collected through 18 semi-structured interviews with industry experts and analyzed using open, axial, and selective coding. The findings led to the identification of six critical stages in the technology transfer process: technology assessment and needs analysis, alignment with local infrastructures, partner selection and transfer strategy, technology absorption and localization, organizational learning and empowerment, and cyclical monitoring and development. The final model, derived from the integration of theoretical and empirical evidence, provides a practical and indigenous framework for managing technology transfer in the leather and footwear sector. The novelty of this research lies in the development of a stage-based, context-specific, and dynamic model that not only emphasizes local learning clusters and institutional engagement but also incorporates environmental considerations and sustainability into the technology transfer cycle. As such, the proposed model represents an innovative framework that can be extended to related industries such as textiles and apparel.The primary objective of this study is to design an indigenous, problem-oriented framework for technology transfer in Iran’s leather and footwear industry.

At the heart of this movement is the search for eco-friendly alternatives to conventional synthetic dyes and mordants, which often pose serious risks to human health and the environment. This search is progressing rapidly. Research findings have shown that natural dyes—traditionally derived from plant, animal, or mineral sources—have become promising alternatives to synthetic dyes due to their environmental compatibility and sustainability. Scientists are increasingly focused on understanding the chemical structures of these dyes, developing a wider range of color shades, discovering new natural dye sources, and overcoming the limitations of natural dyes. This article reviews the results of extensive research on the latest developments in identifying eco-friendly dye sources and bio-based mordants, as well as strategies for reducing the environmental impact of mineral mordants. It also presents the latest achievements in various dye extraction methods, including modern technologies such as ultrasonic extraction, supercritical fluid extraction, and microwave-assisted extraction, in comparison to traditional methods. The efficiency and functional properties of natural dyes are also discussed, including medicinal benefits, deodorizing effects, antibacterial and antimicrobial properties, moth repellence, and UV protection. Research results indicate that, despite the growing application of natural dyes across different scientific fields and the documented contributions of countries and researchers in this domain, there is still a need for more in-depth studies to adapt natural dyes to dyeing machinery and to improve dyeing efficiency and quality.The growing awareness of pollutants from the textile industry and synthetic dyes has led to a revolutionary shift in the textile sector towards sustainability.
