The flame resistance of needle-punch material made from a blend of thermostable fibres was investigated.The dependence of the flame resistance on the process parameters of the needle-punch heat-insulating material was established.The maximum value of the oxygen index of 39% was attained at a punch density of 150 l/ cm~2 punching depth of 10 mm,and polyester fibre content of 10%.Addition of low-combustibility polyester fibre in the blend allows reducing the cost of the raw material and price of the material,with good flame resistance of the finished materia~l.
