The future development direction of circular knitting machine parts: intelligent drive, green upgrade and global collaboration

The future development direction of circular knitting machine parts: intelligent drive, green upgrade and global collaboration. Under the wave of the textile industry’s transformation towards intelligent manufacturing and green low-carbon, circular knitting machine parts, as a core supporting link in the industrial chain, are now entering a critical period of technological iteration and market reconstruction. Relying on the empowerment of Industry 4.0 technology, the drive of environmental protection policies and the traction of diversified market demands, its future development will focus on four core directions: in-depth penetration of intelligence, comprehensive upgrading of greenness, breakthrough in high-end and global coordinated layout, promoting the transformation of the industry from scale growth to quality and efficiency. I. Intelligence and Digitalization: Reconstructing the Efficiency of the entire Production chain. Intelligent upgrading has become the core driving force of the accessories industry, achieving a dual leap in production efficiency and precision through technological integration. In the future, iot modules will be widely embedded in accessories to build an intelligent closed loop of “perception - analysis - decision-making - execution”. For instance, the intelligent yarn feeding device is equipped with self-learning algorithms, which can adapt to the characteristics of different yarns in real time and dynamically adjust the tension, reducing the fabric defect rate by more than 30%. Core components such as electronic needle selectors and servo drive systems will be upgraded towards high precision and fast response, with processing accuracy exceeding 0.005 millimeters, meeting the refined production requirements of personalized knitted products. The in-depth application of digital twin technology will reshape the equipment operation and maintenance mode. By building virtual images of accessories, it can achieve wear prediction, fault early warning and remote diagnosis, reducing equipment maintenance costs by 32% and shortening downtime by 40%. Meanwhile, the integration of industrial Internet platforms will break down information silos. By 2030, the penetration rate of spare parts with iot interfaces is expected to exceed 60%, forming a cross-device and cross-factory collaborative production network, supporting flexible manufacturing and rapid order response. The delivery cycle for small-batch customized orders will be compressed from the traditional 7 days to within 72 hours. Ii. Greening and Sustainability: In response to the Global low-carbon transformation, under the dual impetus of increasingly strict environmental protection regulations and the green transformation of industries, the accessories industry will practice the concept of sustainability throughout the entire chain, from materials, processes to recycling. The material end will widely adopt environmentally friendly materials such as low-carbon alloys and biodegradable polymers, and develop energy-saving components like high-efficiency motors, enabling a single device to save up to 12,000 kilowatt-hours of electricity annually and reduce energy consumption by more than 18%. Environmentally friendly lubrication systems, lead-free coated needle hooks and other products will become the mainstream in the market. The proportion of their R&D investment is expected to increase from 4.1% in 2023 to over 8% in 2030. The circular economy model will be accelerated to be implemented, and the repair and reuse of accessories will be achieved through technological innovation. If ultra-high-speed laser cladding technology is adopted to spray the metal-based ceramic composite powder to form a wear-resistant layer, not only can the service life of the syringe be extended by 30%, but also the discarded syringes can be repaired and regenerated, reducing resource waste. Meanwhile, the industrial chain will build a green supply chain system, achieve raw material traceability through blockchain technology, ensure that the entire production process complies with standards such as the EU CE and domestic environmental protection certifications, and promote a steady increase in the proportion of export products. Iii. High-endization and Localization: Breaking Through Core Technological Barriers In view of the current high dependence on imported high-end components, domestic substitution and breakthroughs in high-endization will become important issues for the development of the industry. In the future, efforts will be focused on breaking through “bottleneck” products such as high-precision syringes and high-end bearings. Through collaborative innovation among industry, academia and research, the core technological level will be enhanced. For instance, the heat treatment technology will be optimized to increase the wear resistance of syringes by 50%, narrowing the gap with top international brands. It is expected that by 2035, the import dependence on high-end heat treatment syringes will drop from the current 45% to below 20%. Modular design will become an important direction for product innovation. Developing standardized accessories that can be quickly disassembled and interchanged can meet the adaptation requirements of different models and reduce the cost of equipment upgrades for enterprises. Meanwhile, the research and development of special accessories for emerging application scenarios will accelerate, such as special yarn guides suitable for carbon fiber yarns and precision triangular devices required for the production of medical textiles. Among them, the market demand for special settling plates used in automotive interiors will maintain an average annual growth rate of over 24%, becoming a new growth engine. Iv. Globalization and Synergy: Laying Out a Global Industrial Network With the transfer of the global textile industry and the adjustment of the trade pattern, the accessories industry will accelerate its global layout, forming a collaborative system of “technology research and development in the core area, production and manufacturing in the cost area, and service network in the market area”. In emerging textile bases such as Southeast Asia and Africa, local production and service centers will be established to meet the demands of newly-built textile industrial parks in countries like Vietnam and Indonesia, shortening the supply cycle and service radius. It is expected that the revenue contribution from overseas markets will increase from the current 32% to over 45% by 2030. The industrial chain collaboration will develop in depth and diversification. Upstream raw material enterprises and accessory manufacturers will jointly build a special material research and development platform, such as developing dedicated stainless steel wire to extend the lifespan of syringes by 30% while reducing procurement costs by 12%. Downstream complete machine enterprises and component manufacturers jointly carry out customized development, forming a “complete machine - component” collaborative innovation ecosystem. Meanwhile, by participating in the formulation of international standards and obtaining global certifications, the international discourse power of Chinese components can be enhanced, promoting the entry of domestic high-end components into the mainstream markets of Europe and America, and achieving a global breakthrough from “Made in China” to “Intelligently Made in China”. In the next decade, the circular knitting machine parts industry will witness a dual improvement in market scale and quality and efficiency, driven by technological innovation, green transformation and global layout. It is expected that by 2031, the market size in China will exceed 15 billion yuan, and the global market size will reach 5 billion US dollars. The industry will gradually transform from a follower to a leader, providing core support for the high-quality development of the global textile industry.
