The Application of Paper Machine Shoe Press Felt

The Development of Shoe Press Felt in the Paper Industry

With the rapid development of China’s papermaking industry, large high-speed paper machines are increasingly favored by people. To further enhance the operating speed of these machines, engineering technicians in the paper and paper machinery industry have exhausted all means to improve the dewatering efficiency of paper machines. Further increasing the dewatering efficiency of the press section is undoubtedly economical and effective. Consequently, the widespread application of shoe presses has played a notable role in improving the dewatering efficiency of the press section in paper machines.

Previously, all domestic shoe press devices and shoe press felt required imports. However, in recent years, through the joint efforts of paper industry technicians, shoe press devices have achieved complete localization, further promoting the widespread application of shoe press technology in various types of paper machines and for producing different types of paper.

Over a decade ago, nearly all the felt used for shoe press in China relied on imports. In recent years, the rapid development of the papermaking industry has also driven advancements in the paper machine felt sector, leading to the emergence of domestically produced paper machine felt that fully meet the operational requirements of high-speed paper machines equipped with shoe presses.

Sun Hong Shoe Press Felt Advantages and Services

In recent years, SUN HONG engineering and technical personnel have fully leveraged their strengths in both hardware and software for product development, leading the industry by developing a dedicated shoe press felt with complete independent intellectual property rights for shoe press, which has been widely applied in numerous high-speed paper machines equipped with shoe press.

The shoe press felts developed by our company feature a ring-shaped endless oblique weave multi-axial monofilament base net composite structure, representing a product with high technical content and superior performance. Made from imported raw materials and utilizing imported heavy-duty wide-width equipment along with domestically designed and manufactured specialized machinery, these felts are widely used in high-speed packaging paper machines, high-speed cultural paper machines, high-speed tissue machines, and high-speed specialty paper machines equipped with shoe press. They demonstrate exceptional resistance to compaction and elastic recovery, outstanding uniformity in structure and water filtration, as well as unparalleled surface smoothness and fineness—delivering irreplaceable advantages. These shoe press felts can fully replace imported counterparts and have earned consistent praise from users.
