Rieter systems aiding sustainable yarn production

Rieter systems aiding sustainable yarn production

Minimum environmental pollution, maximum power consumption savings, optimum use of resources: These are just some of the factors that Rieter has considered for decades when developing new products. The spinning systems offer customers sustainable yarn production and long-term profitability.

When developing sustainable machines, systems, and services, Rieter considers the entire life cycle of the machines. The focus here is on saving energy and optimum use of resources, as well as efficient and economical production to remain competitive (refer Figure 1).

Sustainable Raw-Material Utilization

Rieter spinning technologies ensure good utilization of raw materials, which can optimize fiber consumption. Rieter systems can be used to process bast fibers or recycled fibers into rotor yarns or ring yarns. These types of fiber are playing an increasingly important role in yarn production. Rieter is driving these innovative solutions for the sustainable use of raw materials.

Rieter offers customized, economical solutions for preparing bast fibers such as flax or hemp for short-staple spinning mills (Figure 2). Preparation is an important precondition for spinning the bast fibers. For the preparation process, Rieter cooperates with the German company Temafa. The machines enable fibers to be extracted from straw bales. The fibers are shortened and refined until they are similar to cotton fibers in length and fineness. This process is called cottonizing. The prepared fibers are best spun using a rotor spinning machine. Rotor yarn offers advantages over ring yarn in terms of elongation, hairiness, and downstream processing.
