A few days ago, a foreign start-up company called ThermalTech launched a new solar smart fabric made of stainless steel yarn and used this fabric to create a series of solar jackets.
When the wearer is out, the stainless steel yarn smart fabric of this jacket can absorb solar energy to provide heat for the wearer to keep it warm, so the wearer does not need to wear a heavy coat in the cold winter.
It is reported that this smart fabric made of stainless steel yarn is light and breathable, and it keeps warmer than traditional heating jackets.
