What type of clothing materials are worn by astronauts and fireman. Why
Answers
Answer:
Astronauts and firefighters wear uniforms or specialty garments made from synthetic fabrics to ensure their safety. It may surprise you to know that their uniforms incorporate a lot of the same materials, even though their jobs are radically different. The fabrics in space suits and firefighting uniforms are flexible but offer insulation from extreme temperatures and debris.
Firefighters wear suits made of Nomex or Kevlar. Both are fire-resistant materials which help to protect the firefighter from catching aflame or from sustaining burns when nearby fire. Sometimes, Nomex and Kevlar are blended together. Nomex also insulates against electric charge, which prevents firefighters from being electrocuted.
Nomex is also used in some astronaut clothing. Space suits are made of many layers of protective and insulating materials to ensure durability, flexibility, and insulation. Another important fabric in space suits is called Chromel-R- it helps to keep the astronaut's body heat inside the suit and protect against extremely cold temperatures outside the suit. This fabric is especially important for the hand or glove parts of a suit, as astronauts sometimes handle objects which are very cold!
