On December 6, the 2023 Science and Technology Awards Ceremony of the China National Textile and Apparel Council (CNTAC) was held at the Great Hall of the People. The project "Key Technologies and Industrialization of High-Efficiency, Energy-Saving, and Digital Stenter Series Intelligent Equipment," undertaken by Yoantion Industrial (301053), Donghua University, and Zhejiang Sci-Tech University, won the First Prize of the 2023 CNTAC Science and Technology Progress Award.
Over a decade of effort and sucessful breakthroughs in technical barriers .The CNTAC Science and Technology Awards, approved by the National Science and Technology Awards Office (Certification No. 0093), are one of the highest honors in China's textile industry. They recognize entities and individuals who have made outstanding contributions to technological advancements in the textile sector, promoting innovation and improving the industry's technical and competitive strength. The awards uphold a fair and rigorous selection process, relying on professional, objective, and authoritative evaluation methods. With input from the government, industry experts, and the media, the nominated projects undergo stringent selection and comprehensive evaluation by a review committee, making the CNTAC Science and Technology Awards known as the "Light of Textiles."

The stenter process addresses the extensibility of fabrics post-dyeing, where the binding force of fiber molecules weakens at high temperatures. Using high-temperature multiphase medium heat exchange, this process eliminates internal stress and high-elastic deformation in fabrics, improving colorfastness and dimensional stability. However, setting consumes around 40% of the total energy in dyeing, with more than 60% of this energy being wasted as high-temperature exhaust gas, leading to significant energy waste and environmental pollution. The technical bottleneck lies in the complexity of multiphysical field coupling in this process, making modeling and regulation difficult.
Yoantion Industrial's project team spent over a decade overcoming these barriers and made several innovations: They analyzed the mechanisms of heat and mass transfer under multi-field coupling interaction and proposed methods for regulating heat transfer using a hybrid medium and compound phase change to reduce energy consumption and improve heat utilization efficiency.
The team introduced a dynamic parametric control method based on fluid dynamics for large inertial flow fields and developed a matrix-style multi-source heat exchange model, optimizing nozzle, duct, and oven structures. They also designed an innovative double-layer stenter, which reduces energy consumption, space, and labor costs.
Advanced techniques for high-precision processing of combined roller shafts and adaptive control of long-range, wide-format dynamic tension were developed, enabling accurate control of stenter equipment components and the setting process, thus improving both product quality and efficiency.
The team also created an expert system for setting processes, utilizing big data and deep learning to develop an embedded optimization system, enhancing the intelligence of setting production.
Innovative Development Empowering High-Quality Growth in the Textile Industry
The textile industry has traditionally been associated with high pollution and energy consumption. However, a group of pioneers focused on technological innovation, product advancement, and sustainable practices has driven the industry toward a smarter, more efficient, and environmentally friendly future.
From its inception, Yoantion Industrial has targeted the mid-to-high-end domestic market, relying on a skilled technical team and advanced manufacturing equipment to build its brand and reputation. The company's flagship product, the hot-air stenter, has not only improved product quality but also contributed to energy-saving efforts in the textile industry, facilitating its high-quality development.
Yoantion's self-developed "Y9000 Double-Layer High-Efficiency Energy-Saving Digital Stenter" was included in the 2021 list of "First Set Products in Zhejiang Province." The "Y2088 Series Hot-Air Stenter" was recognized as a new industrial product in Zhejiang and received certifications such as "First Set Product in Key Areas of Zhejiang's Equipment Manufacturing Industry" and "Zhejiang Province Energy-Saving Product." Additionally, the company's "New Non-Thermal Oil Hot-Air Stenter" was awarded the "Major Science and Technology Project of Key Provincial Enterprise Research Institute" and was named a "First Set Product in Key Areas of Zhejiang's Equipment Manufacturing Industry" in 2018.
Yoantion Industrial has consistently maintained technological innovation as its core competitive advantage, continually optimizing its product lineup and developing in a multi-layered and specialized direction. This has led to the establishment of an innovation model of "producing one generation, developing one generation, and cultivating one generation." By enhancing its innovation capabilities and competitive strengths, the company meets evolving market demands and leads industry development.
In recent years, Yoantion has built a comprehensive R&D system and mastered key technologies such as "hot-air stenter control systems," "automatic filter technology," "automatic centering technology," "automatic sizing technology," and "heat recovery technology." The company has been recognized as a National Key Supported High-Tech Enterprise, a Provincial Key Enterprise Research Institute, a Provincial R&D Center, a Municipal Patent Demonstration Enterprise, and a Zhejiang Province Hidden Champion Enterprise. Yoantion's continuous innovation and development have been widely recognized, providing strong momentum for the company's growth and leadership in the industry.
With the trends of smart manufacturing and green development, Yoantion Industrial will continue to follow national industrial policies and meet the textile industry's demands for structural adjustment and upgrading. Guided by market and customer needs, the company will prioritize innovation, sustainability, and quality to drive high-quality growth in the textile industry.
