摘要： A fire blocking non-woven needlepunched textile structure, comprising a first fiber component containing polyacrylonitrile copolymer with a halogen containing monomer and a second fiber component. The second fiber component is selected such that it supports the first fiber component during burning, optionally including an inorganic filler as a coating for the first and second fiber components. In alternative embodiment, the present invention provides a fire blocking non-woven textile structure containing the above first and second fiber components, blended with a third binder fiber component in the form of a vertically lapped nonwoven structure.
