報−２０２６０１９に記載されている。Water-absorbing fibers and flame-resistant fibers have been widely known. Examples of acrylic water-absorbent fibers include swellable fibers made of acrylic polymers containing carboxyl groups in the form of salts (Japanese Patent Laid-Open No. 57-77312) and new water-swellable fibers (Japanese Patent Laid-Open No. 55-36360). ). Furthermore, flame-resistant fibers have been known as intermediate products in the carbon fiber manufacturing process, and are described, for example, in West German Patent Publication No. 2026019.
一方、近年、防災に対する関心は高まるばかりで、防災
頭巾や、消火布のニーズも増大している。On the other hand, in recent years, interest in disaster prevention has only increased, and the need for disaster prevention hoods and firefighting cloths has also increased.

近になって、難燃繊維や、耐炎化繊維からなる防災布が
使用されつつあるがその効果は必らずしも顕著ではない
。However, in the event of a fire, it has been common practice to evacuate by soaking a blanket or sheet with water, or dampening a cloth with water and covering it over the fire to extinguish the fire. It is. Recently, disaster prevention fabrics made of flame-retardant fibers or flame-resistant fibers have been used, but their effects are not necessarily significant.

かった。Conventional blankets and the like impregnated with water have a limited water retention capacity, which poses the problem that the blankets themselves can catch fire in more severe fires or when used for long periods of time. On the other hand, disaster prevention fabrics made of flame-retardant acrylic or flame-retardant fibers are less likely to burn even if all the water evaporates, and although they are effective in that respect, they cannot suppress the transfer of heat, and there is a significant difference in the risk of burns. There was no.

Alternatively, when used as a disaster prevention hood, a plastic bag filled with water can be folded together into a blanket such as a disaster prevention hood, and when used, it can be crushed and impregnated with water.
以下に本発明の布帛を実施例により説明する。 The fabric of the present invention will be explained below using Examples.

た。P L3u! A single fiber with a denier of 2d made of a copolymer of 80% by weight of acrylonitrile and 20% by weight of acrylic acid was prepared at 25°C in an ethanol-water mixed solution of 2% caustic soda (60% ethanol, 40% water). After immersion for 2 minutes, the fibers were dehydrated and dried to obtain water absorbent fibers with a water absorption capacity of 70 times. This fiber was cut into a length of 51 am, passed through a card, and then made into a nonwoven fabric by needle punching to obtain a fabric (A).

exceeded. Furthermore, a commercially available disaster prevention hood (with a fabric weight of approximately 500 g/m consisting of an aluminum layer on the surface, a flame-retardant acrylic batting, and a cotton lining) was tested for flame resistance in the same manner with the aluminum layer facing down. As a result, 60 in 5 minutes
It exceeded ℃. As described above, the fabric of the present invention exhibited excellent flame resistance and heat resistance, which were not found in conventional products.
