Method for manufacturing polyacrylonitrile fiber cloth and fireproof cloth made of such cloth
A kind of fireproof cloth includes a piece of polyacrylonitrile fiber cloth; to make the polyacrylonitrile fiber cloth, first polymer of polyacrylonitrile is spun into fiber, and flame-resisting treatment is carried out on the polyacrylonitrile fiber in air, and next the polyacrylonitrile fiber is woven into polyacrylonitrile fiber cloth; because of the flame-resisting treatment, the polyacrylonitrile fiber has high strength, high elasticity and heat isolation capability, and is highly resistible to instantaneous high temperature; the polyacrylonitrile fiber cloth has excellent water absorbing capability therefore structure of the fireproof cloth won't be damaged when the fireproof cloth is washed with water.
1. A fireproof cloth made of polyacrylonitrile fiber cloth, comprising:
a first fireproof layer including polyacrylonitrile fiber cloth,
a second fireproof layer including an oxidized fiber cloth material having a melting point of at least 900° C., and positioned on a lower side of said first fireproof layer; and
a third fireproof layer including a flame resistant cloth and positioned on a lower side of said second fireproof layer;
wherein a piece of material containing thermoplastic and cotton is positioned on a lower side of said polyacrylonitrile fiber cloth.
