High Efficiency and Quality for Recycled Wool with the R 37

Jiangyin Haoshun Textile Co., Ltd., a wool fabric manufacturer based in Jiangyin, has brought previously outsourced spinning operations in-house to strengthen cost and quality control. In 2025, the company expanded its capacity and introduced the R 37 rotor spinning machine, along with the C 77 card and RSB-D 55 draw frame, for processing recycled wool. The rotor spinning capacity now reaches 2 040 rotors, ensuring a stable supply of high-quality yarn for the company’s own fabric production.
Overcoming Capacity and Quality Limits in Rotor Spinning
In the initial phase of the project, Haoshun utilized competitor machines for rotor spinning production. However, with business expansion, the existing capacity could no longer meet the demands of downstream fabric production. Furthermore, the production of double-faced wool fabrics imposes stringent requirements on yarn consistency and stability, as any quality fluctuations could directly impact fabric performance.
Efforts to boost output and improve yarn quality were limited by existing equipment. Competitor machines had low capacity, and controlling imperfections and ends-down rates in recycled wool was challenging, reducing both quality and efficiency. Raising capacity and quality within the current set-up was also a major challenge.
Spinning Smarter to Achieve Superior Efficiency and Consistent Quality
Haoshun conducted multiple trials with different materials at the Rieter spincenter. Compared to machines from competition, the R 37 demonstrated outstanding performance across various indicators, exceeding expectations.
The R 37 offers excellent spinning stability and a low ends down rate, with a delivery speed up to 200 m/min. Its redesigned spinning box with exchangeable trash channels improves trash extraction and adapts well to recycled wool.
Combined with the time-saving AMIspin piecing device, it achieves high production efficiency. The machine is also energy-efficient, featuring a modern drive that reduces operating costs.
Higher Productivity, Better Quality, Lower Costs
Haoshun benefits from impressive advantages thanks to the use of the R 37:
- Increased Productivity: The delivery speed of the R 37 is approximately 50% higher than that of machines from competition. Combined with stable machine efficiency of over 98%, this has significantly boosted production capacity.
- Optimized Quality: The yarn produced by the R 37 features a unique structure, achieving lower twist levels while maintaining the same yarn strength. The optimized spinning box minimizes imperfections when processing recycled wool, enhancing spinning stability.
- Cost Savings: The R 37 significantly reduces labor demand due to its low ends down rate and high spinning stability. Furthermore, its modern drive concept enables a 20% reduction in energy consumption per ton of yarn compared to competitor machines, which leads to effective control of total production costs.

In this competitive wool market environment, the introduction of the Rieter R 37 has proven to be a successful strategic investment for our company. It effectively addresses our challenges in production capacity and cost by boosting output by approximately 50% while achieving lower energy consumption per ton of yarn. The yarn produced by the R 37 has a unique structure, resulting in a fuller fabric appearance and a softer hand feel of our wool fabrics. It achieves lower twist levels without compromising yarn strength.Ailong Zhou, Chief Engineer
