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.
Compact spinning was founded way back in 1999. Soon after in 2003, mechanical compact spinning was invented. But only right now, with new technology and better systems available, we see the mechanical side of compact spinning gain more traction among spinners. Until now, pneumatic compact spinning was widely adopted, only for spinners now to realize, that mechanical compact spinning is going to be the future. Why is that?
Spinning is a vital operation process in the textile sector. The fashion industry is highly dependend on the yarn manufacturers and the yarn export of spinning mills. Recently, intensified by the worldwide crysis and rising energy and oil prices, the perspective of a more environmentally friendly production reaffirms itself. Both, the retailer demand and the demand of the government points towards more sustainablê ways of production. In the upcoming years, it will not only be a choice to make. Companies will also be forced to take necessary steps. The ones who do not comply, will certainly fall behind. The possibility, that this leads to further extrusion of some companies in the market even after the crysis remains very high.

Compact spinning is a process, where fiber strand drawn by drafting system is condensed before twisting it. Compact spinning was introduces in the 90’s and developed around the year 2000. The benefits of compact spinning are widely known and described in professional literature (improved hairiness, tensile strength and elongation), however the additional expenditures forced many spinners to reject the implementation.While in the past, there was a price benefit for compact yarn on the trade-market, this is no longer the case. Today, there is no up-payment for compact yarn anymore. But the significant production benefits of compact spinning still remain prevalent up until this day. Though, most technologies lack consistency and a propper technology. Many spinning mills have witnessed failure in the past. Prior technology clearly disappointed. Technology has matured since then and it has now become possible to adopt compact spinning at about the same cost as conventional spinning – which makes compact spinning lucrative and profitable.
