T-shirt of this fabric will save you in any heat
Some clothing manufacturers equip their jackets sensors monitor the state of health and other electronics. Such functions are certainly interesting, but most consumers expect from the clothes is very trivial thing - it is important that it is warmed in the cold and refreshing in the heat. Fortunately, some of the research team are well aware of this - so, for example, researchers from the University of Maryland (UMD) developed by adapting the temperature of the material from which it is possible to make excellent sport shirts.
enables researchers fabric inspired an important feature of the human body - it exchanges heat with the environment by means of thermal radiation. Manufacturers of sportswear already use increases the capacity of the materials, but their properties are active all the time, not just when it is needed.
To fabric responsive to changes in body temperature during physical activity, researchers have created it from yarn consisting of two fibers and absorbent repelling moisture. Due to different reaction to moisture, perspiration at the fiber body are pressed together - the thread becomes thinner and the pores are formed tissue. fabric also has carbon nanotubes, which enhance its emissivity.
If you look at what is happening the whole picture, it turns out that when you exercise the human body is cooled in two ways at once. Firstly, it is vented through the pores in the T-shirt. Second, nanotubes help the body to give more heat. When a person is at rest and does not sweat, the material retains the optimal temperature, and one does not feel excessive cold.
To test the efficacy of the tissue, the researchers put it in a container with controlled humidity. By measuring its transmittance, researchers have found that with an increase in humidity more than 90% transmittance, respectively, is increased to 35, 4%.
the creation of materials for the "clothing of the future" are engaged in many research groups and companies. Sometimes they do not need to create - at the end of 2018 company Fast Company has released a jacket of graphene, which is also perfectly removes and retains heat depending on the ambient conditions.
