How to develop the polypropylene industry with high quality in the new stage? This will give the company confidence

In order to implement the overall requirements and key tasks of the “Guiding Opinions on the Development of High Quality in the Chemical Fiber Industry”, we will promote technology, intelligence, greenness and health in the polypropylene industry. Development, from April 25 to 26, the 2023 Polypropylene Branch Annual Meeting and the New Stage High-Quality Development Forum of the Polypropylene Industry were held in Changzhou. At the same time, the polypropylene industry chain was organized to display innovation results. Lu Jiabin, vice president of China Chemical Fiber Industry Association, and Wu Wenjing, deputy secretary-general, attended the meeting. This conference is hosted by the China Chemical Fiber Industry Association and hosted by the Polypropylene Branch of the China Chemical Fiber Industry Association, Changzhou Lingda Special Fiber Co., Ltd., Changzhou Fubang Chemical Fiber Machinery Factory and China Polypropylene Network.

This meeting coincides with the change of the polypropylene branch of the China Chemical Fiber Industry Association. More than 200 experts, scholars, researchers and representatives of upstream and downstream enterprises in the polypropylene industry chain gathered in Changzhou to discuss the development plans of the polypropylene industry. The meeting was chaired by Li Zengjun, chief economist of the China Chemical Fiber Industry Association.

Leader’s speech

Lu Jiabin, vice president of the China Chemical Fiber Industry Association, said in his speech that since the epidemic, especially in 2022, the development environment at home and abroad has become more complex and severe. The combined effects of multiple complex factors such as repeated epidemics, geopolitical conflicts, and high inflation have led to The global economic growth continues to slow down, domestic and foreign consumer demand has been significantly suppressed, and my country’s chemical fiber industry has encountered unprecedented challenges.

Lu Jiabin said that although the polypropylene industry will also be under pressure in 2022, polypropylene, as a small but excellent chemical fiber variety, can not only meet the demand for high-quality functional fiber materials in the textile, clothing and industrial fields, but also comply with the national green Development concept and strong endogenous motivation. As various domestic policies are gradually implemented and effective this year, the polypropylene industry still has great room for development and potential. Lu Jiabin said that my country has the most complete textile and chemical fiber industry chain in the world, and the collaborative and efficient market system strongly supports the sustainable development of upstream and downstream industries. Domestic consumer confidence is gradually recovering, and high-quality consumer demand is also increasing. These are all industries. The confidence of stable development, therefore, enterprises in the polypropylene industry should also have confidence in this.

Awarding Ceremony

During the meeting, the unit awarding ceremony for the third president and vice president of the Polypropylene Branch of the China Chemical Fiber Industry Association was held.

Forum report

Development of new functional polypropylene fibers

Professor Chen Long from the School of Materials Science and Engineering of Donghua University summarized the current status of the development of the polypropylene fiber industry and fiber technology development, and introduced the research results of related research groups using blending melt spinning technology to control dispersed phase distribution, focusing on The development process of polypropylene fibers with high specific surface area (taking uneven surface fibers as an example), compound system flame-retardant polypropylene fibers, and the use of recycled waste lunch boxes to produce fine-denier polypropylene fibers and fabrics, as well as related results in engineering infrastructure Field reinforcement (such as concrete fiber, asphaltgeotextile, etc.), fire-proof fabrics and sportswear applications, and finally the future technology research and development of polypropylene fiber in the clothing and industrial fields Trends are prospected.

China’s chemical fiber industry economic Situation Analysis and Outlook

Since 2022, the global economic downturn has been obvious, and the “triple pressures” of shrinking domestic demand, supply shocks, and weakening expectations have also increased. The operation of my country’s chemical fiber industry has encountered unprecedented challenges. Wu Wenjing, deputy secretary-general of the China Chemical Fiber Industry Association, analyzed the current economic operation situation of the chemical fiber industry and believed that although the operation of the chemical fiber industry is facing pressure from both supply and demand ends, with the development of various domestic Policies to stabilize growth will continue to be implemented in detail, and the endogenous driving force for economic growth will continue to accumulate and strengthen, providing positive support for the recovery of domestic consumption.

Development of hydrophilic and hydrophobic functional additives and polypropylene fiber

The application of fluorosilicone materials, especially fluorinated silicone, fluorinated acrylate, fluorinated silicone oil and other polymer technologies, plays an important role in the hydrophilic and hydrophobic modification of polypropylene. Zhou Lu, a professor at the School of Chemistry and Chemical Engineering at Nanjing University of Science and Technology and director of the Lingda Advanced Materials Research Institute, introduced the synthesis process of a variety of fluorine-containing hydrophilic and hydrophobic additives and demonstrated the Specific examples of external coating or internal addition to improve fiber hydrophilicity and hydrophobicity.

Preparation technology and application of ultra-high molecular weight polyethylene fiber

Professor Yu Junrong from the School of Materials Science and Engineering of Donghua University introduced the preparation technology of ultra-high molecular weight polyethylene fiber, hoping to provide new ideas for the innovative development of the polypropylene industry. Yu Junrong sorted out the forming process of ultra-high molecular weight polyethylene fiber using gel spinning-superdrawing method, and each stage (including gel spinning raw material selection, swelling and dissolution preparation of spinning solution, solution filtration and deaeration , extrusion, quench forming, extraction and drying of gel fiber and super hot stretching, etc.), and introduced the main application fields of ultra-high molecular weight polyethylene fiber and the current status of domestic and foreign industries.

Polypropylene differentiated fiber manufacturing technology and innovation

From the second step�, the annual meeting of the Polypropylene Branch of the China Chemical Fiber Industry Association held a general election, and the meeting approved the third president and vice-president units of the Polypropylene Branch of the China Chemical Fiber Industry Association. The specific list is as follows:

Chairman unit: Guangdong Mengtai High-tech Fiber Co., Ltd.

Executive Vice President: Li Zengjun of China Chemical Fiber Industry Association

Vice president units (in no particular order):

Zhejiang Jincai New Materials Co., Ltd.

Ningbo Dazhong Chemical Fiber Industrial Co., Ltd.

School of Materials Science and Engineering, Donghua University

Changzhou Lingda Special Fiber Co., Ltd.

Hubei Botao Synthetic Fiber Co., Ltd.
