Orderly development of poly3-hydroxyalkanoate (PHA), polybutylene succinate - co-butylene terephthalate (PBST) and other materials industrialization promotion and application.

Fourth, accelerate digital and intelligent transformation

(1) Strengthening the research and development and application of intelligent equipment. Promote the research and development and application of equipment such as large integration, low energy intelligent logistics, automatic drum dropping, automatic packaging, and improve the level of fiber automation and intelligent production. Accelerate the development and application of automatic spinning device and online quality monitoring system of polyester elastic equipment, improve the intelligent level of spinning and winding equipment of polyester, spandex and nylon.

2. Promoting digital transformation of enterprises Promote the application of emerging digital technologies such as artificial intelligence, big data and cloud computing in chemical fiber enterprises, and improve the digitalization level of all aspects of the industrial chain such as R&D, design, production and manufacturing, warehousing and logistics. The application of digital technology to open up enterprise business processes, management systems and supply chain data, to achieve organizational structure optimization, dynamic precision service, auxiliary management decision-making and other management model innovation, improve enterprise management capabilities.

(3) Carry out the construction of industrial Internet platforms. Key enterprises are encouraged to build industrial Internet platforms that integrate master data, real-time data, applications, identity analysis, management information systems, and business intelligence to support enterprise digital transformation and industrial chain modernization. Promote upstream and downstream enterprises in the industrial chain to realize resource data sharing through the industrial Internet platform, strengthen the docking of supply and demand, and promote the collaborative development and application of the whole industrial chain.

Box 4 Collaborative innovation and systematic solutions for intelligent manufacturing

1. Build a standard system for intelligent manufacturing. Carry out research and formulation of standards for intelligent equipment, interconnection, intelligent workshops and intelligent factories in the chemical fiber industry, and give priority to strengthening the construction of intelligent manufacturing standard systems in polyester, nylon, spandex, recycled cellulose fiber, recycled polyester and other industries.

2. Improve the level of key technologies of intelligent manufacturing. Improve the technical level of intelligent raw material distribution, intelligent cake management, production data analysis, and intelligent three-dimensional warehouse. Improve 3D design and modeling, numerical analysis, process simulation, product lifecycle management (PLM), distributed control (DCS), Manufacturing execution (MES), enterprise Resource Management (ERP), data acquisition and video surveillance (SCADA) and other industrial control software and systems.

3. Improve the level of intelligent service. Using cloud services, intelligent analysis and other technologies, collect and analyze customer feedback information, while solving customer problems, feedback and guide enterprises to improve product design, production, sales and other links to improve customer satisfaction.

Fifth, promote green and low-carbon transformation

1. Promoting energy-saving and low-carbon development We will encourage enterprises to optimize the energy mix, expand the proportion of wind power, photovoltaic and other new energy applications, and phase out coal-fired boilers and heating furnaces. Formulate a carbon peaking roadmap for the chemical fiber industry, clarify the implementation path for carbon reduction in the industry, increase the research and development of green processes and equipment, strengthen the transformation of cleaner production technologies and the promotion of key energy saving and emission reduction technologies. Accelerate the construction of green factories, green products, green supply chain and green parks in the chemical fiber industry, carry out the construction of demonstration enterprises leading in water efficiency and energy efficiency, and promote the construction of carbon footprint accounting and social responsibility.

2. Improving recycling. To achieve large-scale and low-cost production of chemical recycled polyester, and promote the research and development and industrialization of key technologies of recycled nylon, recycled polypropylene, recycled spandex, recycled acrylic, recycled viscose fiber, recycled high-performance fiber and other varieties. Promote the key technological breakthroughs and industrial development of the high-value utilization of waste textiles, increase the recycling and utilization of used military uniforms, school uniforms, police uniforms, tooling and other uniforms, and encourage relevant production enterprises to establish a recycling system.
