ICUST develops "air conditioner" clothes smart fiber adjustable temperature

Tianjin North News: Air conditioning can not only be placed indoors, it can also be worn on the body. However, this air-conditioning is different from the traditional air-conditioning, it is by Tianjin University of Technology Zhang Xingxiang and other newly developed an intelligent heat storage temperature control fiber. The temperature-controlled textile made of such fibers has the same insulation performance as ordinary textiles of the same specification, and its internal temperature is lower or higher by 3° C. than ordinary textiles in an environment of temperature increase and temperature reduction, and makes the human body feel comfortable.

The clothes can also automatically adjust the temperature in the heat balance, the human body feels the most comfortable skin temperature is 33.4 °C, if the temperature difference exceeds plus or minus 4.5 °C, the body will have a cold and warm feeling. In order to make the human body feel comfortable, it is necessary to add or subtract clothes in time according to changes in the external environment such as ambient temperature, humidity, wind speed, and light, in order to maintain the balance between heat production and heat dissipation.

Ordinary textiles or garments mainly serve to maintain the normal temperature of the human body in the garment by blocking heat transfer between the human body and the external environment. Heat storage and temperature control fiber is a high-tech fiber that automatically senses changes in the external environment and intelligently regulates temperature. The main purpose of this fiber is to improve the comfort of the garment. The fabric absorbs, stores, redistributes, and releases heat, making the temperature within the garment more comfortable. The thermal storage and tempering textile technology plays an equally important role in improving the comfort of the garment as the waterproof and breathable fabric. The heat storage and tempering textile technology was selected as one of “21 changes in human life in the 21st century”.

Applied to the development of new flight suits Tianjin University of Technology successfully developed smart heat storage temperature control fiber is an important technology of China's fiber, textile industry, its technology and products have reached the international advanced level, the project product has been in the development of new flight suits Has been applied, and has a great potential market in the field of civil sports clothing and **special insulation, stealth camouflage.

Tianjin University of Technology has been researching and developing heat storage and temperature control materials since the 1990s and has been authorized 3 invention patents. It is the deepest research group with the widest research scope at home and abroad, and has developed excellent thermal storage capacity. Polypropylene fiber and its products, and the production of thermal storage temperature viscose production experiments. A variety of experimental methods are used to test the thermal insulation and temperature regulation properties of thermoregulated textiles. Thermoregulated textiles have the same thermal insulation performance as ordinary textiles of the same specification, and its internal temperature is lower or higher by 3°C or higher than ordinary textiles during heating and cooling. , duration of up to 30 minutes.

At present, the research results have been used for the research and development of new cold-warming warm clothing by China Aviation Industry First Group Hangyu Lifesaving Equipment Co., Ltd. and the General Logistics Department’s Military Equipment Research Institute. Heat storage and temperature control fiber materials can be used for high-grade clothing insulation materials, bedding and interior decoration products, professional clothing, shoes, caps, socks, gloves and so on. Can also be used for flying suits, space suits, paratroopers, fire service, seaman uniforms, wetsuit insulation materials, as well as the field of warfare and field tent insulation and so on.
