Abstract

The present invention relates to a fire hose composed of a weft and warp woven jacket and a polyurethane interior, and more particularly to a fire hose having a weft yarn of polyester filament yarn and a warp woven jacket of polyester spanner.

Description

Fire hose

The present invention relates to a fire hose composed of a weft and warp woven jacket and a polyurethane interior, and more particularly to a fire hose having a weft yarn of polyester filament yarn and a warp woven jacket of polyester spanner.

Usually, the fire hose is composed of a jacket and a lining material woven in a warp and warp. When the interior material is a rubber tube, the jacket is composed of polyester filament yarns with a weft yarn and polyester spanner yarns with a warp yarn.

The fire hose of the rubber-embedding material has a structure in which a polyester span yarn of cotton yarn surrounds a polyester filament yarn of nylon yarn. Accordingly, the nylon yarn is protected by a cotton yarn having a high heat resistance against fire, fire, and the like during fire extinguishing, and the durability of the hose can be improved. However, the rubber lining material has a disadvantage that the weight is heavy.

On the other hand, the fire hose of the polyurethane interior material is woven from polyester filament yarn both in weft and warp yarns, and the polyurethane film layer is used instead of rubber, and the weight is light, but the jacket easily melts due to fire or surrounding heat caused by fire. There is a high risk of losing the function of the hose, and also has a disadvantage that the jacket is nylon yarn, more expensive than cotton yarn in terms of price.

The present invention has been made to solve the above-mentioned problems, and the object of the present invention is to provide a fire hose which can satisfy heat and durability at the same time as well as being light and inexpensive.

Fire hose of the present invention for achieving the above object is a jacket weft and warp (jacket); It comprises a polyurethane tube (polyurethane tube) formed on the inner surface of the jacket, the weft yarn is nylon yarn, the inclination is a cotton yarn is adopted.

Through this configuration, it is not only light and inexpensive, but also satisfies heat resistance and durability at the same time.

In the above configuration, the nylon yarn is a polyester filament yarn (Polyester Filament Yarn), the cotton yarn is preferably composed of a polyester span yarn (Polyester Span Yarn).

Hereinafter, with reference to the accompanying drawings, preferred embodiments of the present invention will be described.

1 is a front view showing a fire hose according to a preferred embodiment of the present invention, Figure 2 is an enlarged cross-sectional view showing a portion A of FIG.

As shown in FIG. 1 and FIG. 2, the fire hose 1 of this embodiment is largely comprised by the jacket 3 and the interior material 9. As shown in FIG.

As shown in Fig. 2, the jacket 3 is woven from the weft yarn 5 and the warp yarn 7, wherein the weft yarn 5 is made of nylon yarn and the warp yarn 7 is made of cotton yarn. The inclination 7 is arrange | positioned at the inner and outer surfaces of the weft thread 5. Nylon yarn (5) is used as the weft yarn because the breaking strength is greater than the cotton yarn (7), because the work pressure (work press) of the water to be injected has more influence on the weft yarn.

It is preferable that polyester filament yarn is used as the nylon yarn 5, and polyester span yarn is used as the cotton yarn 7.

As the interior material 9, a tube of polyurethane film is used. The polyurethane film 9 is made in the form of a tube and adhered to the inner surface of the jacket 3.

As such, the interior material 9 is used as a polyurethane tube to reduce the weight. In addition, the weft yarn 5 of the jacket 3 is nylon yarn, and the inclination 7 of the jacket 3 consists of cotton yarn, and the nylon yarn is wrapped with a cotton yarn with a low price and high heat resistance, Economics can be improved.

Fire hose according to the present invention is not limited to the above-described embodiment can be carried out in a variety of modifications within the range allowed by the technical idea of the present invention.

According to the fire hose of the present invention examined as described above, ① the polyurethane hose is used as the interior material, the fire hose is lighter, ② the nylon yarn as the weft of the jacket, the cotton yarn of the slope of the jacket is used, the heat-resistant cotton yarn Is wrapped around nylon yarns, preventing the nylon yarns from melting due to fire suppression to improve the durability of the fire hose, ③ the jacket is inclined cotton yarn, the price is lower than nylon yarns can achieve a competitive advantage.

Claims (2)
