Rieter K-Conversion – Upgrade of the K-Machine to the Swinsol Mechancial Compact Solution

Introduction Rieter K-frame

It is now possible to spin short staple fibers with a mechanical compact system upgraded to the Rieter machine and achieve the same yarn quality with significantly reduced costs (same cost as conventional spinning) on the Rieter K-frame. Compact spinning was introduced as a trial system in 1995. Later in the year 2000, Rieter introduced an innovation in the air guide providing more fibre compactness. It was called K44-Com4, the Rieter K-frame and it uses suction compact technology. If clean long combed fibers are used, the K-system delivers good yarn results for fine yarns. However, on the sourcing market there are by default less long fibers available. Especially cotton has – by nature – shorter fibres. If the high quality material is not availabe, by our experience, the suction compact will lose its fine-yarn advantage. In reality the K-frame is often used to spin coarser counts and short carded fibers. Pneumatic (suction) compact causes higher cost of material and additional energy consumption. Our upgrade can be used to give the Rieter K-frame a second life to save resources, energy and costs for expensive spare parts. Therefore the economical effect and the cost benefits are significant.
