Significant increase in production of mélange yarns with G 32

The high-quality technology components of the G 32 ensure consistent yarn quality, even when the machine is operated at high speed. The excellent, CVb value contributes significantly to the machine’s simple maintenance.

Chinese manufacturer Huafu Fashion produces high-quality mélange yarns. The company has a production capacity of 1.8 million spindles. This corresponds to around 25 per cent of the total production capacity of mélange yarns or 40 per cent of the medium-quality and high-quality yarns with coloured fibres in China. In Lvshang Textile Town in Aksu City, Xinjiang Province, which is known for its textile industry, the company newly operates 76,000 spindles.

Challenge: High productivity combined with high quality

As a part of the “One Belt, One Road” development strategy and the China-Brazil economic corridor, Huafu wants to increase its production of mélange yarns even further. The Aksu project is a result of these needs. The company was faced with a shortage of labour and rising labour costs. Huafu hoped that, by utilising a high-quality compact-spinning system, it could achieve high spinning stability and yarn quality while lowering maintenance requirements. In addition, Huafu hoped to reduce the large workload of its operating personnel. With these measures, the company wanted to achieve the benchmark it had been striving for in terms of production and quality.

Solution: G 32

For Huafu, Rieter recommended the ring spinning machine G 32 with the compacting system EliTe. The system operates with high stability and features low operating and maintenance requirements. These advantages very much fulfill Huafu’s wish to ensure maximum yield at low operating costs using precision machines. In addition, the G 32 with the EliTe compacting system can be used to produce a consistently high yarn quality over a prolonged period.

Benefits for Huafu Fashion

The project involved 66 x 1,152 spindles, and the complete process from installation to start of production took seven months. For a project of this scale, the decision to opt for Rieter machines instead of machines from other suppliers saved three months of installation time. The high-quality technology components of the G 32 ensure consistent yarn quality, even when the machine is operated at high speed. The excellent, CVb value contributes significantly to the machine’s simple maintenance. Fewer ends down have meant that the number of operators could be reduced by half. This has lowered the operating costs.

The high speed of the machines has reduced Huafu’s production costs per ton of yarn. As a result, the company has increased its overall profit. The investment has been paid back in less time than expected.

The customer’s statement

“With the G 32 with EliTe compact-spinning system from Rieter, we are achieving high yield and efficiency. We produce high yarn quality and achieve excellent spinning stability at the same time. All of these factors result in significantly lower production and operating costs, as well as reduced maintenance requirements. The management team at Huafu is assured that, thanks to the advanced, high-precision ring spinning machines from Rieter, the new industrial park will become a benchmark for the spinning of colourful fibres,” says Kehua Huang, General Manager of Huafu Fashion Xinjiang Grey Yarn Production Base.
