In order to reduce burns caused by fire, flame retardant fabrics are the last line of defense to ensure user safety, so the protective properties of flame retardant fabrics are very important, especially comfort, flame retardant and fire shrinkage. Only these three indicators meet the requirements of national standards at the same time, can better play a protective role.Gasoline Portable fire pump
After contact with flame and hot objects, flame retardant suits prevent themselves from igniting, burning or smouldering for a certain period of time, Gasoline Portable fire pump protecting workers from open flames or heat sources. Therefore, the performance of flame retardant suits is very important, especially comfort, flame retardant and fire shrinkage. Gasoline Portable fire pump Only when these three indicators meet the requirements at the same time, can the protection function be better played.
At present, there are many kinds of flame retardant fabrics used in the market, including flame retardant cotton, modified flame retardant polyester, arylon series (such as arylacrylic, acrylic), etc., but there are few high quality flame retardant fabrics that are comfortable, flame retardant and fire reducing. Because no fiber is perfect, they all have their own strengths and weaknesses.
Flame retardant fabric although comfortable, but low strength, low temperature resistance, 180℃ carbonization; Aramid fiber, acrylic fiber, interposition aramid fiber shrinkage in fire, moisture absorption is small, poor comfort; Paracaramid has high temperature resistance, shrinking in fire, but poor comfort; PBO (polyp-styrene and dioxazole) fibers do not shrink in fire, but are currently not localized and are expensive. In addition, because polymer fiber hygroscopicity is small, wearing comfort is poor.
Comfort, flame retardant and high temperature shrinkage of flame retardant fabrics are also important. Only by integrating these three functions into the fabric of the flame retardant suit can it provide better protection for the wearer. In order to meet the requirements of these three properties of flame retardant clothing, existing enterprises in China developed aramid blended flame retardant fabric with cellulose flame retardant fiber as the base material and para-aramid fiber as the skeleton, taking into account the comfort, flame retardant and thermal shrinkage of flame retardant clothing fabric.
