(57) [Summary] [Objective] The object of the present invention is to obtain the required properties as an industrial heat-resistant felt such as papermaking tools, that is, heat resistance and physical properties. Provided is a nonwoven fabric heat-resistant felt (hereinafter referred to as heat-resistant felt), which is made of a heat-resistant fiber made of a new fiber having a high degree of mechanical durability as a base fabric and / or a web. [Structure] The heat-resistant felt according to the present invention comprises an aliphatic polyamide (hereinafter referred to as nylon 6-) which is polycondensed with hexamethylenediamine and terephthalic acid and has an aromatic ring in the main chain. (Referred to as T) as a main component, a base fabric composed of a part or all of heat-resistant fibers obtained by melt-spinning a thermoplastic resin, and / or a part or all of a web formed on one side or both sides of the base fabric. Is composed of the heat resistant fiber. |
