Rieter K 48 reduces energy consumption in spinning by 18 percent

SpinningRieter K 48 reduces energy consumption in spinning by 18 percent

-Spinning News Sponsor -

A recent comparison conducted in a Turkish spinning mill shows an 18% lower energy consumption for the compact-spinning machine K 48 compared to the competition. For a machine with 1 824 spindles, this benefit equates to an annual saving of around 12,000 USD per machine. This once again demonstrates Rieter’s strong claim for the energy efficiency of compact-spinning technology. The findings are not only important for the success of Rieter and its customers, but also contribute to a more sustainable and economic future for the textile industry.

The trials at a Turkish customer were carried out on compact-spinning machines with spindle speeds at 19 200 rpm to produce 100% cotton compact yarn with count Ne 30. The energy consumption figure in kWh per kg yarn is one of the key indicators in spinning mills. The advantage becomes clear with 1.21 kWh/kg for the K 48 versus 1.48 kWh/kg for the competitor machine. This also confirms the result of another comparison with K 48 for a cotton yarn with count Ne 40 at 19 500 rpm.

Rieter machines make a difference in energy-saving

The largest energy consumers in compact spinning are the spindle drive (75 to 80%) and the suction system (12 to 17%). Further drives account for a large proportion of the remaining energy consumption (7 to 10%). The efficient suction system is mainly responsible for the great advantage of Rieter compact-spinning machines. Competitors’ machines all require an additional suction system for the compacting process, which means considerable additional energy consumption.

The LENA spindles are also an important feature for lower energy consumption. Their design and efficiency directly impact the kWh per kg yarn, with 6% energy saving possible compared to standard spindles.

Apart from the suction system and spindle dynamics, the efficiency of the main motor drive proves to be an important determinant of energy consumption. Rieter’s commitment to optimal energy utilization is underlined by using up to 110 kW, highly efficient main motors with IE4 technology.

Lower energy costs offer tangible economic benefits

For a machine with 1 824 spindles, the 18% reduction in energy consumption corresponds to an annual saving of around 12,000 USD per machine, based on energy costs of USD 0.1 per kWh. The lower energy costs make Rieter machines a strategic investment with a tangible return and keep Rieter one step ahead in the sustainable production of compact yarns.
