Domestic yarn setting machines must vigorously develop energy efficient machines. The development of the yarn setting machine industry has been rapidly increasing in terms of the number of products, the number of enterprises, the production and sales volume, and the market holdings. There has been a dizzying change. According to estimates by Zhejiang Shaoxing Textile Association, in 2010, the output of yarn-only setting machines in China has exceeded 10 million units. There is no doubt that China has become the world's largest producer of yarn steaming machines. From the reality of energy consumption, China is facing new challenges in environmental issues. Therefore, improving the energy efficiency of yarn steaming and setting machine and strengthening operation management are effective ways to cut peaks and fill valleys and alleviate China's power bottleneck, and have far-reaching strategic significance for China's economic development and environmental protection. At present, the country is revising the energy efficiency standards of yarn steaming machines, which will require a significant increase in the energy efficiency of yarn setting machines. At the same time, we should also see that China's steaming machine manufacturers are always in a state of no pressure and no power for energy saving. The power consumption of the product is low and the waste is serious. Especially for some small business products, special machines, etc.
