FLAMMABLE CLOTHS All these synthetic cloths mentioned previously are flammable. Flammable means that these are textiles that can burn easily. Most of them are wrinkle free especially poliester.But if they need to be ironed it should be done in very low temperatures and carefully. That’s why firefighters or firemen uniforms are made of a special cloth resistant to fire.Though they are made from synthetic cloths they have some other chemicals that make them resist fire to some extent. Theaters,audutoriums, and other places that gather large crowds have curtains made from cloths that do not burn easily. It is done this way in case a fire occurs.

DURABILITY When we talk about durability we talk about something lasting for a long time. The majority of cloths have durability especially when good care is given to it. Most of them do not fade their color even when they are exposed frequently to the sun.. Time passes by and they keep the same shape even when they are washed several times. This always happens with the synthetic cloths like poliester lycra,nylon, and rayon
