Sewing Machines and Processes

Sewing Machines and Processes presents modern engineering fundamentals of sewing processes and machines for the complete spectrum of sewing stitches. It explores various needle types, properties of sewing threads, material transport, and advances in sewing techniques and technologies.

Yordan Kyosev has been head of the chair of assembly technology for textile at ITM, TU Dresden since 2019, where he teaches courses related to joining flexible materials (sewing and welding machines and processes, machines for the preparation of apparel production, product development for apparel production). From 1997 to 2005, he was an assistant professor at TU Sofia, where he taught the construction and development of sewing and textile machines, technical mechanics, and knitting technology. From 2006 to 2019, he was professor at Niederrhein University of Applied Sciences. Dr Kyosev is the founder and main developer of the company TexMind, which provides software for the engineering development and simulation of textile structures, sewing stitches for their joining, and the processes of the formations of both structures and stitches. He uses his software packages (Braider, Braiding Machine Configurator, Warp Knitting Editor, Stitch Creator, TexMind Viewer) to generate large numbers of illustrations and pictures in his books. He is also editor-in-chief of the Journal of Engineered Fibers and Fabrics, published by SAGE (IF 0.814) and the journal Communications in Development and Assembling of Textile Products.
