The domestic 50,000 tons polyester staple fiber crimping machine was successfully developed.

In order to continuously adapt to the trend of polyester staple fiber drawing equipment towards large capacity development, Zhengzhou Textile Machinery Hongda Chemical Fiber Machinery Co., Ltd. is the first in the country to realize the annual output of 30,000 tons of crimping, cutting, baling machines and other models, constantly A large number of scientific and engineering engineers invested in research and development of new products, and successfully developed the HV746 50,000 tons of polyester staple fiber crimping machine.

The machine has been used by Sinopec Luoyang Petrochemical Complex and Sinopec Yizheng Chemical Fiber for more than half a year. The equipment runs smoothly, with advanced performance, high technical content, low noise, no pollution, high energy, high precision, and the use of the unit's leadership and technology. The personnel gave the machine full recognition.

Zhengzhou Textile Machinery Co., Ltd. is a subsidiary of China Textile Machinery Group Co., Ltd. It is a professional manufacturer of chemical fiber drafting equipment for chemical fiber crimping, cutting and baling machines. In recent years, the company has closely adjusted this main line around product structure, following the group spirit of “synergy, excellence and innovation” of China Textile Machinery Group and the competitive strategy of “low cost, differentiation and rapid response”. Under the scientific decision-making of the core leadership team, we have made great efforts in research and development of high-tech and high-value-added products, in order to continuously adapt to the trend of international and domestic polyester staple fiber drafting equipment to the direction of large capacity.


The success of the HV746 50,000-ton crimper marked the company's high-capacity polyester staple fiber after-treatment equipment to a new level. On the basis of accommodating the world's advanced technology, the machine has highlighted humanized and intelligent design, and is a highly sophisticated product that keeps pace with the development of the times.

The machine is extruded, most of the parts are stainless steel parts, and the surface processing precision is high. The machine consists of a crimping box component, a frame pneumatic component, a press arm transmission component, a crimping seat component, a rotary joint component, and a pressing component. The main technical parameters are: tow fineness of 550~600Ktex, crimping roll width of 550~600mm, crimping roll diameter of 303mm, mechanical speed of 250~300m/min, and weight of the whole machine of 9000Kg.

The crimping machine is known as the “Queen's Product” in its high-tech high-precision and high-precision products, and is a key part in the chemical fiber drafting process. The R&D and production of the HV746 50,000-ton crimping machine has successfully filled a domestic technical gap.
