The "Digital Control Technology for Fabric Stenter" independently developed by Changzhou Hongda Intelligence Technology Co., Ltd. has been successfully included in the *Recommended Catalogue of Energy-Saving and Carbon-Reducing Technologies and Equipment in the National Industrial and Information Technology Sector (2025 Edition)* issued by the Ministry of Industry and Information Technology (MIIT). This national-level authoritative recognition not only fully affirms Hongda Intelligence's technological innovation but also provides core support and a demonstration path for textile dyeing and finishing enterprises across the country to promote energy saving and carbon reduction and achieve high-end intelligent transformation. Below, the editor provides a detailed interpretation of this key industry technology.

1. Industry Pain Point Terminator: AI "Precision Setting" Says Goodbye to Inefficient Waste Driven by "Experience"

Fabric setting is a highly energy-intensive process in dyeing and finishing, heavily reliant on manual intervention and experience-based adjustments. Quality indicators of the set fabric lack detection and control, leading to repeated setting, high energy consumption, and unstable quality. Relying on the HK-AI artificial intelligence large model for printing and dyeing, HONDA Intelligence achieves real-time sensing, intelligent control, and predictive optimization of key process indicators throughout the entire process. After application, "precision setting" is realized: the first-pass success rate of setting increases by approximately 15%, and the comprehensive energy saving rate reaches 12%.

2. National Policy Support: Inclusion in the Catalogue = "Fast Pass" for Priority Assistance

This technology has passed national authoritative review and has been incorporated into the key promotion system for energy-saving and carbon-reducing technologies. For enterprises, this represents policy dividends: local industry and information technology departments offer special funds and subsidies. Early adopters will benefit sooner, effectively reducing technical transformation costs and accelerating green transformation.

4. Dual Advantages of Cost Reduction & Efficiency Increase: 12% Energy Saving + 15% Quality Improvement – Direct Gross Profit Rise

Implant an "artificial brain" into the stenter. Based on existing equipment process control, it precisely controls key quality indicators such as fabric feeding status, fabric temperature inside the drying chamber, setting time, exhaust energy-saving control, fabric grammage, and width, achieving "precision setting." The comprehensive energy saving rate is about 12%, reducing steam costs by approximately 10%; the first-pass success rate increases by 15%, reducing rework and defective products, shortening delivery times, and achieving both capacity and quality improvements.

5. A New Name Card for Intelligent Manufacturing in China: Breaking International Monopoly and Reshaping Industry Discourse

The core technology for high-end fabric setting has long been monopolized by foreign countries. Hongda Intelligence has achieved a key technological breakthrough through independent innovation, successfully breaking the foreign monopoly. This technology is not only hardcore equipment for enterprise energy saving and carbon reduction but also a name card for the independent and controllable nature of China's intelligent manufacturing. By empowering industrial upgrading with technological innovation, it injects strong momentum into China's textile industry as it strives to reach world-class standards and achieve high-quality development.

01 What value does this system deliver to textile enterprises?

This system fundamentally resolves persistent pain points in traditional stenter processes, including large parameter fluctuations and unstable fabric quality. It can raise the first-pass yield of fabric finishing by around 15%, greatly cut energy waste from repeated reprocessing, and achieve an overall energy savings rate of approximately 12%. It supports textile dyeing and finishing enterprises in transforming from the traditional high-energy, high-emission model toward green and intelligent manufacturing. By lowering production costs and effectively reducing carbon emissions, the system helps enterprises meet their carbon reduction targets while realizing both economic and environmental benefits simultaneously.

02 Based on existing equipment and process control, this technology builds an AI-driven large model for textile dyeing and finishing. It controls key quality indicators such as fabric feeding status, fabric surface temperature in the chamber, setting time, as well as fabric GSM, width and other parameters, enabling real-time perception, intelligent decision-making and dynamic adjustment during the entire fabric setting process. The primary success rate of fabric setting has been increased by approximately 15%, reducing process energy consumption caused by repeated fabric setting, with a comprehensive energy saving rate of around 12%.
