Investigations into designing the individual cutting components of knitted garments made from elastane yarns for wearing close to the body (e.g. swimwear and sportswear) have been the subject of numerous publications in recent times. This research, carried out at the Institute for the Textile and Clothing Industry (Institut für Textil- und Bekleidungsindustrie), Dresden, presents intermediate research results on textile/physical tests carried out on a variety of materials, suggestions for carrying out the product development process using virtual, 3D models of figures or anatomical bodies, and the automatic generation of two-dimensional cutting components. Particular reference is made to the use of CAD/CAM systems and design software, recommendations for processing different seam lengths, and developing cutting components for specific types of sportswear, e.g. competitive cycling wear.
