Description

Three-scale modelling and numerical simulations of fabric materials offer a sophisticated and multifaceted approach to comprehending and enhancing the behaviour of textiles across various domains. This methodology leverages the integration of three distinct scales, namely the micro scale, musicale, and macro scale, each contributing to a holistic understanding of fabric performance. The significance of this approach lies in its ability to predict and analyse how fabrics respond to an array of mechanical, thermal, and environmental factors, thereby facilitating the optimization of textiles for durability, safety, and functionality in diverse industries. At the micro scale, it delves into the behaviour of individual fibres and yarns, exploring their mechanical properties and damage mechanisms. The musicale bridges the gap between micro and macro by examining fabric structure and arrangements, enabling predictions related to elasticity, anisotropy, and permeability. Finally, the macroscale scrutinizes the fabric as a whole, accounting for large-scale deformations, stress distributions, and interactions with external forces. Overall, this approach empowers industries such as fashion, aerospace, automotive engineering, and architecture to harness the full potential of fabric materials through precise modelling, simulations, and optimization, ultimately driving innovation and sustainability in textiles [1].

Three-scale modelling and numerical simulations in the realm of fabric materials find their essence in a systematic process that unfolds through several key stages. It initiates with the comprehensive characterization of material properties at each scale, beginning with the microscope, where individual fibbers’ mechanical attributes are scrutinized through experiments or microscopic analysis. Subsequently, musicale and macro scale properties are derived from micro scale data, integrating structural considerations and the material's macroscopic behaviour. Mathematical and computational models are meticulously developed, reflecting the intricacies of fabric behaviour at each scale. These models encompass finite element analysis for micro scale fiber behaviour, lattice models or discrete element methods for mesoscale fabric structures, and continuum mechanics equations for macro scale fabric responses. Numerical simulations, underpinned by computational methodologies like finite element analysis, finite difference methods, and computational fluid dynamics, are conducted based on these models to predict fabric performance under diverse conditions. Crucially, validation through experimental testing ensures the fidelity of predictions to real-world observations, anchoring the reliability and applicability of these models. Ultimately, the predictive power of three-scale modelling and numerical simulations transcends various industries, from textiles and aerospace to automotive engineering and architecture. These techniques enable the precise design and optimization of fabric materials, which is indispensable for achieving desired properties, enhancing performance, and ensuring the safety and durability of textile-based products in the modern world [2,3].

The practical applications of three-scale modelling and numerical simulations in the context of fabric materials are vast and transformative. Across diverse sectors, these techniques hold the potential to revolutionize the design, performance, and sustainability of textiles. For instance, in the textile industry, they facilitate the development of fabrics with tailored properties such as moisture wicking, thermal insulation, and UV protection, ensuring that textiles meet specific functional requirements. In aerospace engineering, where lightweight materials are critical, three-scale modeling assists in designing textiles for applications like parachutes and airbags, optimizing their performance under extreme conditions. The automotive industry benefits from the predictive power of these models by improving the safety and comfort of vehicle interiors and exteriors, enhancing automotive textiles' performance and durability. Architects and designers employ three-scale modeling to predict the behaviour of fabric-based architectural structures like tensile membranes and shading systems, ensuring structural integrity and performance under diverse environmental conditions [4].

The review also underscored the importance of interdisciplinary collaborations between researchers, chemists, toxicologists, and healthcare professionals. Such collaborations can foster a comprehensive understanding of the health risks posed by textile dyes and enable the development of effective mitigation strategies. Furthermore, the potential environmental impact of textile dyes should not be overlooked. Efforts should be made to minimize the release of dyes into water bodies during dyeing processes, as well as to explore ecofriendly dye removal and wastewater treatment methods. In conclusion, the systematic and citation network analysis review provides a valuable overview of the current knowledge and research trends regarding textile dyes and human health. It emphasizes the need for further research, standardized testing methods, and improved risk communication to ensure the safe and sustainable use of dyes in the textile industry. By addressing the identified knowledge gaps and implementing appropriate measures, we can strive for a fashion and textile sector that prioritizes human health and environmental well-being. In the realm of medical textiles, these techniques play a crucial role in assessing biocompatibility and mechanical performance, particularly for implantable textiles and medical garments. The potential applications extend even further, encompassing sports textiles, geotextiles, and beyond [5].

Three-scale modelling and numerical simulations have become indispensable tools for a broad spectrum of industries, driving innovation, enhancing product performance, and contributing to sustainability by minimizing resource consumption and waste. As computational methods and material science continue to advance, the impact and applications of these techniques in the field of fabric materials are poised to expand, shaping the future of textiles and materials engineering.
