This saves process steps, production time and manual labour, and often improves material efficiency. With the help of the 3D circular knitting technology, these ad-vantages can be used in the production of automotive seat covers. However, for the application of 3D circular knitted fabrics in a serial production of automotive seat covers, a process chain for processing is necessary. Since such a process chain does not exist, neither 3D circular nor 3D flat knitting technology has yet been used to implement serial production of automotive seat covers. The implementation of a process chain for processing 3D circular knitted fabrics is technically demanding and complex, because in 3D circular knitting technology the 3D shape of the end product is already achieved during textile production. As a result, the textiles can no longer be rolled up after production and pro-cessing, and processing must be carried out in individual pieces. This change represents a paradigm shift in the textile process chain. The objectives of the present work are therefore to develop a process chain for manufacturing and processing 3D circular knitted automotive seat covers and to evaluate the usability of 3D circular knitted automotive seat covers in automotive interiors. The accomplishment of the objectives is supported by two methodological approaches in the present work: A methodological procedure for the technical development of the knitting technology and the processing procedure, and a method for the economic-technical evaluation. The technical development is structured using a procedure based on VDI Guideline 2221 and the PDCA cycle (PDCA = Plan-Do-Check-Act). The economic-technical evaluation of the 3D circular knitted automotive seat cover fabrics is based on the practical development process for automotive seat covers of a supplier: the stage-gate process. A benchmark comparison is used to evaluate the economic viability of the 3D circular knitting technology, and the costs of the processing process are deter-mined with the aid of a one-stage overhead calculation.
