Automation in production of yarns, woven, and knitted fabrics

Abstract The production of yarns and sewing threads is highly automated. A long tradition in automation of the spinning process is mainly based on the experience of a few machine manufacturers. Improvements in automation in garment manufacturing are mainly focused on fabric production. Three knitting processes are compared regarding automation, productivity, and flexibility. In addition the quality inspection of knitted structures is evolving to a camera-based automated monitoring system that needs to cover the complexity and variety of knitted structures. An approach in self-optimization is described for weaving machines to autonomously find an operating point, which improves all objective functions, compared with conventional (reference) machine settings. By the development of on-loom imaging solution the online monitoring of the weaving quality becomes possible and reduces waste at an early stage of production.
