Unlike textiles and plastics materials , the requirements for flame retardant effect not only good, but also must meet textile processing technology, resistant to washing ( dry cleaning and washing ) , sun-resistant , non- droplet , low smoke emission , low toxicity, skin irritation , no smell, no moisture absorption , low price range requirements. In retardant textile research work, low smoke and low toxicity , inexpensive and efficient, had no effect on the original fiber properties for the current key research topics .
Single component retardant textile relatively easy to solve the problem , and the natural fiber and chemical droplet fusible fibers, interwoven fabric flammability stronger, which is due to heat fusion fiber case , one of the natural fibers are the same as the wick , the melt bulk liquid absorbing polymer to promote further decomposition and oxidation, combustion is more prosperous. As people used polyester / cotton blended products retardant technology is still a worldwide problem .
In order to fibers made from natural ingredients , seaweed fiber has good flame resistance , up to 34% of its LOI , seaweed fibers from brown sea algae extract , our rich marine resources , some institutions are engaged in retardant textile fiber production with algae research . Without flame retardant to achieve the flame retardant fabric effect is the best way, but in the process , the manufacturing cost so much work needs to be done .
