The manufacturer of polyester fibers Trevira GmbH, Bobingen/Germany, and the development services company imat-uve GmbH, Mönchengladbach/Germany, have together enabled the use of 3D flat knitting technology for automotive interiors. In a jointly developed process that unites innovative yarn technologies with cutting-edge connection and finishing techniques, Trevira and imat-uve have found a way of producing anatomically contoured seat covers and trim components for vehicle interiors.
Because the technology uses just one knitting process rather than several, manufacturers can reduce their production and materials costs, as it is no longer necessary to cut and assemble the fabrics.
Trevira and imat-uve are the first companies to develop such a sophisticated application of the knitting process for use in vehicles, thanks to imat-uve’s innovative processing and finishing technique which deploys a low-melt yarn specifically developed by Trevira. The 3D flat knitting technology even means that areas known to be vulnerable, such as the seams on seat covers, can be strengthened in the course of the same single knitting process. Another benefit of the technology is its contribution to sustainable manufacturing. Not only does it work on the zero waste principle, but the knitted fabric itself is manufactured entirely from yarn made from PET recyclate.
