Advanced Digitization and CAD Simulation: Technological Convergence, Skills, and Innovation for a Circular Fashion Industry

Abstract

The digital transformation in the textile and apparel industry has reinforced the role of advanced CAD systems to supporting more sustainable and circular practices. Technologies such as CAD/CAM, 3D garment simulation, material digitization, and digital twins are increasingly integrated into product development, enabling waste reduction, improved efficiency, more sustainable use of materials and less reliance on physical prototyping. This study is based on a systematic literature review with focusing on CAD systems, digital representation of fabrics, and textile circularity. The obtained results highlight that the reliability of simulation is strongly dependent on the accuracy of digital models of the materials and their parameterization. The literature analysis identifies two main approaches in simulation systems. While fashion-oriented platforms prioritize the visual realism and rapid design iteration, the technically oriented systems are focus on the accurate representation of the structure the materials and their physical properties. The integration of these two approaches is a key challenge and opportunity for improving simulation reliability. The findings also show that the integration of CAD systems with artificial intelligence and digital twin technologies is emerging as a key driver of innovation, enabling for more efficient digital workflows and the reducing reliance of physical prototyping. The adoption of these technologies can support sustainability through the reduction of materials and improved decision-making, although challenges remain in modelling recycled materials, ensuring data consistency, and integrating digital workflows.
