Hello, I'm
Textile Engineer
Specializing in Yarn Engineering, Fiber Science, Sustainable Production System. Aiming to integrate research insights with practical applications in modern textile manufacturing.
Hello, I'm Nazim. I completed my B.Sc. in Textile Engineering from Bangladesh University of Textiles (BUTEX), specializing in Yarn Engineering. I am currently enrolled in an M.Sc. in Textile Engineering at BUTEX to further advance my knowledge in fiber science, advanced materials, and process optimization. Alongside my postgraduate studies, I have pursued a Post Graduate Diploma in Garment Business (PGD-GB) from the Institute of Business Administration (IBA), University of Dhaka, which has strengthened my understanding of the business and strategic aspects of the apparel industry.
My academic foundation is rooted in fiber science, process optimization, and sustainable product development, with a strong inclination toward innovative and environmentally responsible technologies. During my studies, particularly through my internship at Multazim Spinning Mills Ltd., I gained hands-on experience in spinning operations, quality control, and material innovation.
Driven by the goal of developing high-performance and sustainable textile solutions, my interests span reinforcement fibers and composites, biopolymers, conductive polymers, smart textiles, and circular textile systems. I am especially passionate about biodegradable polymers, eco-textiles, geotextiles, nanotechnology, and advanced waste recycling strategies.

Vortex spinning has become one of the most interesting innovations in the modern yarn production that provides high-speed production and fine homogeneity of yarns as compared to the traditional spinning peripherals. In this review, an elaborate description of the underlying mechanism of spinning of vortices is given with specific focus being put on the aerodynamic fiber manipulation that allows the assembly of yarns by swirling air streams. The analysis of structural properties of vortex yarn is carried out in detail with emphasis placed on the unique core-sheath structure where new cores are coated by helically oriented wrapper cores. These architectural subtleties have a decisive impact on the final physical and mechanical characteristics of the yarn, including tensile strength, hairiness, uniformity and abrasion. The review also evaluates the performance of fabrics made with vortex yarns, in particular the performance in terms of comfort, durability, pilling resistance and dimension stability. These are comparative studies of the spinning modalities that had been developed like ring spinning, rotor spinning among others to help portray advantages and limitations of vortex technology. Further, the suitability of vortex spinning to diverse types of fibers; cotton, synthetic, regenerated fibers is also analyzed critically. The results show that vortex-spun yarns are more productive and less hairy, although there are some limitations concerning the yarn strength and the necessary fiber length. Overall, this review summarizes the available information about vortex spinning technology and outlines potential future research directions that could help optimize the quality of yarns and increase their application in high-performance and functional textiles.
Bangladesh’s RMG sector generates over 84% of the country’s export earnings, yet it operates almost entirely on a linear model: extract, produce, discard. This leads to significant environmental and operational challenges. Water pollution, energy inefficiency and accumulating textile waste are the most visible consequences but there’s also a subtler risk building beneath the surface which is that global buyers and regulators are increasingly demanding something different. The circular economy offers a credible alternative pathway, one that could strengthen supply chain resilience, reduce input dependency and bring Bangladesh’s industry into closer alignment with emerging sustainability requirements. However, CE adoption across the sector remains patchy and operationally shallow. This study examines the structural, technological, financial and regulatory barriers that constrain circular transition at the supply chain level and aims to identify and propose feasible transition pathways. Drawing on systematic literature synthesis, policy analysis and industry stakeholder insights, it proposes a phased transition roadmap suited to Bangladesh’s post-LDC graduation context. The findings suggest that, despite genuine obstacles, meaningful progress is possible through closed-loop material flows, waste valorization, green financing and stronger cross-tier supply chain collaboration.
With sustainability emerging as a central concern in the textile sector, the integration of waste fibers into yarn manufacturing offers a means to mitigate environmental consequences. This study investigates rotor yarns produced from brush fiber waste, Droppings-1 waste, and 100% virgin cotton to determine their manufacturing viability and quality attributes. Droppings-1, a recognized waste source in rotor spinning, demonstrated enhanced yarn quality, achieving the lowest Coefficient of Variance (mass%) and Imperfection Index at a 14 Ne count yarn with a 5% waste blend. The 16 Ne, 5% Droppings-1 mixture exhibited the lowest hairiness, although the mechanical performances were maximized at a 10% blend. Conversely, brush fiber, a byproduct of textile finishing procedures, yielded yarn characterized by greater irregularity and diminished mechanical strength owing to its reduced fiber length. It provided a distinctive mélange appearance, minimizing the necessity for further coloring and augmenting aesthetic appeal. The research employed Taguchi analysis and regression modeling to evaluate the impact of waste type, proportion, and yarn count on critical performance indicators. The regression model exhibited an accuracy of over 90% in forecasting yarn qualities for the majority of the parameters. Although virgin cotton yarn demonstrated superior overall performance, Droppings-1 offered a feasible, sustainable alternative with negligible quality degradation. Conversely, brush fiber presented a sustainable and aesthetically impressive alternative for fashion uses. This study highlights the potential of waste-derived rotor yarns in enhancing sustainability, minimizing resource consumption, and facilitating circular economy initiatives within the textile sector.
