Technical Field

The invention relates to a fire hose, in particular to a light fire hose.

Background

The fire hose is one of the key equipment that is used for the fire control water supply, comprises weaving layer and waterproof lining that is used for the pressure-bearing, and the weaving layer adopts dacron material warp, the weft alternately to weave and forms, and traditional weaving layer all adopts the dacron yarn as warp. In recent years, with the improvement of the requirements for fire-fighting and water-proof hoses, the fire-fighting hoses are expected to be more and more perfect in light weight, wear resistance and other properties.

Therefore, the Chinese patent 'a novel mixed-woven portable fire hose' (No. CN 206669137U, No. 11/24/2017) discloses that at least one yarn in the warp is a mixed yarn, and/or at least one yarn in the weft is a mixed yarn. The mixed yarn is formed by winding at least one high-strength high-modulus polyethylene fiber monofilament and at least one polyester monofilament.

However, the braid disclosed in this patent is relatively complicated to manufacture and has poor workability; the polyester filament yarns and the polyethylene fiber yarns are mixed and woven, so that the polyester filament yarns are broken firstly during actual use due to the fact that the polyester filament yarns and the polyethylene fiber yarns are high in strength and elongation difference, and pressure borne by a water belt is affected; in addition, the abrasion resistance of the polyester filament is poor, so that the abrasion resistance of the mixed woven water band is greatly reduced.

Disclosure of Invention

The invention aims to overcome the defects in the prior art and provide a light fire hose, wherein nylon filaments are used for the fire hose to replace conventional polyester filaments so as to reduce the weight of the fire hose and enhance the wear resistance and corrosion resistance of the fire hose.

The technical scheme of the invention is as follows:

the light fire hose comprises an inner waterproof layer and an outer woven layer, wherein the woven layer is formed by weaving warps and wefts, and is characterized in that the warps are nylon filaments or a combination of the nylon filaments and polyethylene fibers, and the wefts are nylon filaments or a combination of the polyethylene fibers or a combination of the nylon filaments and the polyethylene fibers.

Furthermore, the warps are all made of nylon filaments, and the wefts are all made of nylon filaments. The nylon filament used for the warp is 450 nylon filaments of 2000D, and the nylon filament used for the weft is 6 nylon filaments of 2000D.

Furthermore, the warp adopts the combination of polyamide filament and polyethylene fiber yarn, and the weft all adopts polyethylene fiber yarn. The nylon filament used by the warp is 200 pieces of 2000D nylon filament, and the polyethylene fiber used by the warp is 198 pieces of 1200D polyethylene fiber; the polyethylene fiber yarn used in the weft is 2 strands of 1200D polyethylene fiber yarn.

The nylon filament yarn is mainly characterized by high strength (5-6 times of steel wire), high modulus (2-3 times of steel wire), low specific gravity (1/5 of steel wire), high temperature resistance, flame retardancy in light flame, self-extinguishing property, good aging resistance, chemical corrosion resistance, good light resistance (second to acrylic fiber), solarization time of 1000 hours, and 60-70% of strength.

Compared with the fire hose with the same specification and model, the invention has the advantages that the weight is lighter by more than 50% compared with the conventional polyester filament material, and the wear resistance is improved by 2-5 times. The invention is suitable for the fire hose with the diameter of 25mm-200mm in the specification range and the pressure range of 1.3-6.0 MPa.

The nylon filament is used for the fire hose to replace the conventional polyester filament, and has the following advantages:

1. because the strength and the specific gravity of the nylon filament are superior to those of the polyester filament, the weight of the fire hose with the same specification and model can be reduced by producing the fire hose (the specific gravity of the polyester relative to water is 1.38, and the specific gravity of the nylon relative to water is 1.14);

2. the wear resistance of the nylon filament is far higher than that of the polyester filament, so that the service life of the fire hose can be prolonged;

3. the fire hose woven by the nylon filaments is particularly suitable for ships and is resistant to seawater corrosion and solarization.
