Rieter: Mouse

CLEANtube – the option for intelligent control of the coiler speed on the Rieter draw frames – prevents trash particles and short fibers from accumulating in the sliver duct. The result is a mouse-free sliver that assures constant quality and reduces not only operator work but also the amount of waste and the number of ends down.

When processing waste- and noil-rich blends on a draw frame, trash particles and short fibers can accumulate in the sliver duct of the coiler during can filling. Once the can is full, the draw frame stops and this accumulation, known as "mouse", comes to rest on the top sliver layer. This can cause trash deposits in the rotor groove, which in turn result in ends down in spinning. If the mouse gets into the yarn, it causes significant yarn and fabric defects. To avoid this, the mouse is usually removed by the operator which causes additional work & generates soft waste.

CLEANtube – coiling without trash accumulation

CLEANtube ensures that the sliver touches all surfaces of the coiler tube and, thus, keeps it free of accumulations. Pratap Singh Chouhan, General Manager at Gupta Threads states: "CLEANtube is an excellent feature of the Rieter draw frame RSBD 50 for mouse-free sliver which results in quality assurance while reducing the operator's workload". The CLEANtube function of the RSB-D 50 ensures consistent sliver quality and keeps the spinning process at a high efficiency level. It also ensures good quality.

In-mill study shows advantages of CLEANtube

Founded in 2012, Gupta Threads Ltd. is based in Samana, District Punjab, India. In their spinning mill with 3 744 rotor spinning positions, they produce 100% cotton yarn with a count range from Ne 7 to Ne 30. The raw material used is mainly a blend of 60 to 70% waste or comber noil along with 30 to 35% cotton.

An in-mill study at Gupta has shown the following advantages using CLEANtube:
