Lin Wei is a hiking enthusiast. At six o'clock on the last Saturday morning, the temperature at the foot of the mountain was only 2℃, so she put on her thickest fleece jacket. However, after only half an hour of climbing, the heat left her drenched in sweat, making her feel very cold. By midday, the temperature was approaching 20℃, and her heavy jacket had to be tied around her waist, becoming a burden during her hike. This outdoor adventure allowed her to appreciate the beautiful scenery, but also subjected her to repeated changes in temperature.

 

Skier Zhang Chen also experienced this "cold and hot" transition. Ten minutes on the ski lift at -10℃ was enough to make him feel extremely cold. But once he skied down the slope, the exercise made him feel very hot within minutes. During his first ski trip of the season, he constantly switched between feeling "cold" and "hot", and even the best gear proved insufficient to cope with the extreme temperature changes.

 

Temperature changes are a daily challenge for office workers. In the mornings in northern China, Chen Zhe experiences four temperature changes: extreme cold outdoors, stuffy heat in the subway car, cold again after exiting the station, and then warmth upon entering the office building. This is a very common phenomenon. In a special report by CHINA TEXTILE's survey team, 83% of respondents complained about the difficulty of dressing appropriately for the winter weather, and the core problem is the "temperature changes adaptation" ，which is traditional textiles cannot solve.

 

From a textile technology perspective, traditional outdoor gear offers only "passive adaptation" to temperature: either it uses thicker materials to improve warmth, sacrificing lightness and flexibility; or it uses thin, breathable fabrics, compromising protection against cold temperatures.

 

With increasing market competition, outdoor brands are realizing that previous solutions are far from sufficient. The problem is that users still have to regulate their body temperature themselves. The constant attention and manual intervention disrupt the immersive experience of outdoor activities.

 

The more critical problem is that current temperature control efficiency is too low. Traditional outdoor textile materials often lead to uneven heat distribution. While fleece and thicker materials increase warmth, they are also heavy and inflexible. What the market needs now are materials that can actively sense temperature changes and balance temperature differences.

 

In March 2025, at Tokyo Fashion Week, the fashion show of Japanese designer brand Tamme attracted global attention from the fashion industry. The brand incorporated functional fabrics from the FLYTEC Group and iWarm intelligent temperature control products into its designs, winning awards and prompting Japanese media to exclaim: "Chinese technology is redefining the possibilities of fashion."

 

What innovations have led to the market recognition of iWarm's intelligent temperature control solution?  " The purpose of technology is not to "look advanced, but to completely solve problems," iWarm CEO Zhou Juan told reporters. The core of the iWarm intelligent system design is a "sense-think-act" closed loop.

 

The Marketing Director of Yi Technology introduced the core of iWarm to reporters: a 0.3mm flexible heating film. As light and thin as fabric, it can be embedded in the lining of jackets, gloves, or insoles. It heats up in just 5 seconds, offering instant warmth against cold winds. Furthermore, its durability has been proven through 100,000 bending tests, promising a lifespan on par with high-end outdoor gear.

 

What transforms iWarm into an "intelligent system" is its “Sensing to Decision-making “system. High-precision temperature sensors continuously gather data. A miniature CPU then processes this information and, within milliseconds, uses intelligent algorithms to reach a decision. Finally, a temperature controller executes this decision. The entire process is quiet, seamless, and imperceptible to the user.

 

Fang Jiayan summarized this experience as "Supportive". For iWarm, the technology is invisible, serving only to provide a comfortable user experience.

 

You don't need to be distracted by judging and adjusting the temperature; you can simply focus on your current activity. When iWarm "detects" that you are active, it anticipates the rise in body temperature and lowers the temperature in advance; when it "senses" that you've stopped, it subtly increases the temperature to prevent hypothermia.

 

 

All smart experiences must be safe and reliable. iWarm has also embedded "Responsibility" into its system. The hardware features four aspects of protection against overcurrent, overtemperature, short circuits, and low temperatures, combined with automatic power-off after three minutes of inactivity, eliminating potential hazards at the physical level.

 

In addition, iWarm features an IPX-rated waterproof structure, ensuring stable operation even in harsh environments, upgrading from "suitable for outdoor use" to "reliable in all weather conditions." Users can also control the system remotely via a mobile app.

 

This dedication to reliability is rooted in the philosophy of Zhou Juan, "At iWarm, every technical decision and product iteration is built on genuine insights and repeated verification. We only provide product solutions that are truly implementable." This ensures that the technology can withstand the dual challenges of the market and nature.

 

A groundbreaking technology lies in how it reshapes product logic and the industrial ecosystem. The essence of iWarm is an integrated solution of "high-performance fabric + embedded intelligent hardware + dedicated algorithms," providing a plug-and-play, seamlessly integrated intelligent upgrade path.

 

According to Fang Jiayan, iWarm is committed to helping partners achieve "innovative integration": "We provide solutions that highly align with design concepts, enabling products to become market leaders."

 

For end users, it offers a completely new experience. Whether commuting in the city or hiking in the mountains, warmth is always available when needed.

 

Using expert knowledge, scientific methods, and AI, heating evolves from merely generating heat to intelligent control—one that senses, judges, and adapts to conditions. This is the true meaning of "Intelligent."
