See how Zhejiang Tiantai transforms and upgrades to “ultrafiltration, microfiltration, and ultra-clean filtration”
Industrial fabrics in Tiantai County, Zhejiang Province
The industrial fabrics used in Tiantai County are mainly textiles for filtration and separation. Mainly concentrated in Pingqiao Town, an important town in the west of Tiantai County, it has a long history, dating back hundreds of years. Since the 1980s and 1990s, synthetic fibers have been used to produce woven filter cloths and needle-punched nonwoven filter cloths. By 2002, the number of filter cloth entrepreneurs in the county had increased, and the development of the industry had begun to take shape. After nearly 40 years of development, industrial cloth has become one of the six leading industries in the manufacturing industry in Tiantai County.
”Thirteenth Five-Year Plan” results
It is understood that in the early days of the “Thirteenth Five-Year Plan”, affected by the aftermath of the U.S. subprime mortgage crisis, the domestic and foreign market demand for filter materials was relatively weak. By 2016, the global economy began to gradually recover, driven by a sharp increase in commodity prices in the international market. At that time, the production and sales situation of bulk commodities such as steel, metallurgy, minerals, and coal in my country was obviously improving. The industries in which these commodities are located are themselves the main customer groups for Tiantai County’s filter media products. The new Environmental Protection Law has been fully implemented, and the domestic market demand for filter materials has begun to pick up.
After the 19th National Congress of the Communist Party of China, the Party Central Committee listed pollution prevention and control as one of the three tough battles, and the domestic market demand for filter materials began to turn strong. Overall, Tiantai County’s industrial fabricindustrial cluster has been stable and improving during the “Thirteenth Five-Year Plan” period.
During the “Thirteenth Five-Year Plan” period, Tiantai County’s industrial fabric enterprises invested a large amount in equipment, and their advanced nature was significantly enhanced. According to statistics, the needle-punched nonwoven filter material production lines have increased by 50%, that is, they have expanded from more than 40 at the beginning of the period to more than 60. The annual fiber processing volume of nonwovens companies has also increased. increased by more than 50%. The company attaches great importance to the introduction of world-class Aotefa web laying machines, Tritzler and ANDRITZ carding machines.
In order to adapt to the continuously improving quality requirements of filter material customers under ultra-low emission conditions, filter material manufacturers attach great importance to continuous innovation in technology and choose to use compounding and coating. , coating, pleating, multi-component, mixed punching and other process adjustments to promote fiber modification, enhance product performance, and greatly improve product quality. During this period, the independent intellectual property rights of enterprises grew rapidly. It has 15 invention patents and nearly 300 utility model patents. There are more than 100 products listed in Zhejiang Province’s new products.
During the “Thirteenth Five-Year Plan” period, major breakthroughs were made in the forward extension of Tiantai’s industrial chain. In particular, the number of entrepreneurs and the number of production lines that extended forward to produce various types of textile fibers increased exponentially. At the same time, Tiantai County attaches great importance to promoting the listing of enterprises, and has always regarded promoting “small-scale regulation, regulation-share reform, and stock listing” as a key task to promote the development of industrial clusters. Over the past five years, a total of 12 companies in this industry have completed joint-stock reform. Zhejiang Yanpai Co., Ltd. was successfully listed on the GEM of the Shenzhen Stock Exchange in October 2021, opening a new stage in which the industry makes full use of the capital market to achieve leapfrog development.
“Leap-over development initiatives during the 14th Five-Year Plan”
The government has established a school-local cooperation platform to provide intellectual support for the technological research and development and technological innovation of industrial fabrics in Tiantai County
The school-site cooperation platform for the industrial fabric industry in Tiantai County has been established for more than ten years. The main approach is for the government to take the initiative and relevant departments to establish a strategic cooperative relationship with the domestic textile college with strong technical strength, namely the School of Materials, Donghua University, Shanghai. Later, Tiantai County established an industrial fabrics industry with the School of Textile, Zhejiang Sci-Tech University. In the form of research institute, establish strategic cooperation relationship.
The main content of this cooperation is: the two universities will implement 1-2 experts and professors to maintain long-term contact with the industrial fabric industry in Tiantai County. In their busy teaching and scientific research, they find time to regularly visit key enterprises in the industrial fabric industry in Tiantai County to conduct in-depth investigations and timely understand the difficulties and problems encountered by enterprises in the process of technological innovation and technology research and development.
After sorting and summarizing, experts and professors from the two schools were responsible for targeted implementation to help Tiantai County industrial cloth companies solve technical problems. Sometimes, the two schools also send teaching teams composed of several experts and professors to Tiantai County on weekends to train business managers and technology R&D executives on some technical issues. Experts and professors from the two schools provide intellectual support for new product research and development and project application for enterprises in Tiantai County. Over the past decade or so, the practice of school-local cooperation has achieved remarkable results, and the cooperative service platform has been generally welcomed by business owners in the industry.
The “Guiding Opinions” clearly stated that my country’s textile manufacturing enterprises for filtration and separation should adapt to the country’s new situation of ultra-low emissions, carbon peak and carbon neutrality in the future, and focus on the direction of “ultrafiltration, microfiltration, and ultra-clean filtration” The direction of transformation and upgrading of high-performance filter materials and industrial soot carbon capture filter materials has put forward higher technological innovation requirements for Tiantai County’s industrial fabric companies. Tiantai County will focus on the strategic requirements put forward in the “Guiding Opinions” and mobilize the R&D teams of several key enterprises in the industry to conduct specialized research. Donghua will also be invitedProfessors from Henan University and Zhejiang University of Science and Technology came to Tiantai County to conduct in-depth discussions and make arrangements for research and development as soon as possible to seize the opportunity.
The “14th Five-Year Plan” high-quality development plan for Tiantai County’s manufacturing industry clearly states that it requires the Tiantai County industrial fabric industry to be built into a high-quality tens of billions industry during the “14th Five-Year Plan” period. Tiantai County will strive for the support of Tiantai County vocational education, increase the localization of training of technical talent in the industrial cloth industry, mobilize enterprises to actively introduce technical talents, and continuously contribute to the development of the industry Enrich new technological capabilities. Relevant departments will continue to organize enterprises to hold multi-channel and multi-form front-line employee recruitment activities in western my country to effectively solve the serious shortage and aging problems of front-line textile employees. Next, Tiantai County will be problem-oriented and effectively solve the bottleneck constraints of enterprise development to achieve the grand goal of creating a tens of billions industry and make Tiantai County’s due contribution to my country becoming a textile power at an early date.
