By resource efficiency, we mean the optimum use of energy and operating resources to produce a high-quality product on schedule. Resource efficiency on large circular knitting machines is a multi-layered and complex topic which combines technological and business aspects in textile production plants.
In the research project funded by the AiF, the focus is on the optimum consumption of operating resources of the machines, in this case the consumption of lubricant and energy. The investigations are being carried out in the technical center of the Technology Center Knitting Technology.
Large diameter circular knitting machines are lubricated in abundance. This is due to high stresses on materials and machine parts caused by increasing production speeds and the high quality standards of technical and non-technical knitted fabrics. In knitting machines, the lubricant has a cleaning function in addition to its lubricating function. The cam area, which is sensitive to the quality of the fabric, is cleaned of fiber fly and avivages by the lubricant. Due to overflow lubrication, oil consumption is high and the machine is not operated in a resource-efficient manner.
