Embodiment 1

[0026] A hose with holes, its structure from the inside to the outside is like figure 1 As shown, it includes an infiltration layer 1, a braided layer 2 and an outer fiber layer 3; the infiltration layer 1 has holes that allow water to leak (the infiltration layer 1 with holes is represented by a dotted line); the braided layer 2 It has the function of water absorption and can control the amount of water seepage;

[0027] Wherein the braided layer 2 has the function of absorbing water and thus can control the technical effect of water seepage through the following features: the warp and weft fibers of the braided layer 2 adopt cotton-type fibers, and the cotton-type fibers have certain water-absorbing swelling properties. When the water with a fixed working pressure passes through, the cotton-type fiber has a certain water absorption function for the passing water and then expands to make the gap in the braided layer narrow, thereby controlling the water seepage on the surface...

Embodiment 2

[0037] The structure of the hose with holes in this embodiment includes an infiltration layer 1, a braided layer 2, an outer fiber layer 3, and an outer glue layer from the inside to the outside.

[0038] The preparation process of the hose with holes in this embodiment is the same as that of Embodiment 1, except that in step (3), a layer of rubber-plastic alloy outer rubber layer is extruded outside the outer fiber layer 3 .

Embodiment 3

[0040] The structure of the hose with holes in this embodiment includes an infiltration layer 1 and a braided layer 2 in sequence from the inside to the outside.

[0041] The preparation process of the hose with holes in this embodiment is the same as in Example 1, the difference is that

[0042] (1) Extrude and coat PVP K60 on cotton-type polyester staple fiber to obtain a modified warp fiber with a hydrophilic polymer film layer;

[0043] (2) 10 strands of the modified warp fibers are evenly distributed in 240 strands of warp fibers and cross-woven with 250 strands of weft fibers to obtain braided layer 2. Braided layer 2 is plain weave, warp-oriented fibers and weft The fibers are made of cotton-type polyester filament fibers;

[0044] The diameter of the hose obtained in this embodiment is 40mm.

Abstract

The invention relates to a water hose with holes and a preparation method of the water hose. The water hose structurally comprises an inner permeation layer and a braid layer in sequence from inside to outside, and the water hose is characterized in that the inner permeation layer is provided with the holes capable of enabling water to leak, and the braid layer has a water absorption function, so that the water seepage amount can be controlled; the braid layer is composed of modified warp fibers, warp fibers and weft fibers, the modified warp fibers are evenly distributed in the warp fibers at intervals and woven with the weft fibers in a crossed mode, the diameter of the modified warp fibers is larger than or equal to the diameter of the warp fibers and the diameter of the weft fibers, the modified warp-wise fibers are warp fibers of which the surfaces are covered with hydrophilic polymeric membrane layers, and the braid layer can realize a water absorption function so as to control the water seepage amount. The water hose has the effect of no jet phenomenon on the surface under the working pressure, and the surface water seepage amount meets the standard.

Description

technical field [0001] The invention relates to the technical field of fire hoses, in particular to a hose with holes and a preparation method thereof. Background technique [0002] The fire hose has good wear resistance, pressure resistance, corrosion resistance, cold resistance and other properties, and the inner surface of the hose is smooth, and the frictional resistance to the fluid is small, so it can be widely used for laying fire inside and outside the building. Deliver water and fire extinguishing agent to fight fire. At the same time, in areas where water is scarce, fire hoses can also provide long-distance water supply to provide water to fire trucks and fire fighting sites. [0003] The general fire hose consists of a braided layer and a lining layer. The braiding layer is generally high-strength synthetic fiber polyester material, mostly a tubular pressure-resistant skeleton layer woven by high-strength polyester filaments. The lining layer is to coat polymer...
