Your Benefits Of Engineered Fabrics

Less process steps
Warp knitted fabrics, incorporating complex patterns and zones require less pieces to make an article, leading to less cut and sew, reducing production cost.
Fast development
With less components in an end-product, lead time of design changes will be reduced significantly.

Design freedom
Fashion changes can be translated quickly into new fabric designs. Personalized articles or size variations are imaginable.

KM.ON’s k.innovation is revolutionizing the product development process in the knitting industry. In the fast-fashion world, innovation cycles are getting shorter and shorter. Our k.innovation solutions support the customers in developing new products and sharing know-how as well as experience.


Using k.production’s state-of-the-art software and digital solutions, the operation of the KARL MAYER machines will be simplified. Sub-processes are digitally supported and improved. An intuitive and mobile logbook and production data acquisition system will be set up, in which tickets can also be created from entries. Thus, "data tags" for the sensor data are generated immediately. enables you to look at the current production process, regardless of location and in real time. The production data are displayed clearly on a dashboard. This simple way of delivering information improves process transparency and acts as a valid database for decision-making and planning. These advantages are based on KARL MAYER’s own system of machine networking.
