Americans have created a self-recusing fabric
American startup Otherlab has developed a new self-thickening fabric that can be used in the production of new clothes. The new fabric changes its thickness depending on the temperature of the ambient air, and this happens without the use of wires or batteries.
There are no universal clothes, equally well suited for both warm and cool weather. This means that the amount of clothing worn varies depending on the time of year and the temperature of the air. Otherlab decided to design a fabric for universal clothing, which could be worn on clear warm and cloudy cool days.The new fabric is made of several layers, each layer is made of materials that respond differently to changes in the ambient temperature. Some materials are cooled more strongly than others, causing the fabric to fold and air pockets appear between the layers. When the fibers are heated, on the contrary, expand and the fabric becomes flat. It is commissioned by the U.S. Energy Advanced Energy Research Agency as part of the TAM (Thermally Adaptive Materials, Temperature Adaptable Materials) project.
Last September, engineers at Stanford University announced the development of a new semi-synthetic tissue based on nanoporous polyethylene. Such fabric is better than natural and other synthetic materials dissipates the heat of the human body. The new material is a polyethylene that is riddled with connected pores with a diameter of 50 to 1,000 nanometers
