According to the above embodiment, other similar embodiments can be further extended, and it is possible to realize that the pressure-bearing warp 211 and the pressure-bearing weft 221 do not intersect, and the pressure-bearing warp layer and the pressure-bearing weft layer are fixed by weaving the warp connecting lines 212 with the pressure-bearing warp 211 and weaving the weft connecting lines 222 with the pressure-bearing weft 221, and weaving the warp connecting lines 212 with the weft connecting lines 222 in a staggered manner, so that the weaving warp layer 21 and the weaving weft layer 22 are relatively fixed.

Further, as shown in fig. 2 to 6, at the interlaced weaving position of the warp connecting lines 212 and the weft connecting lines 222, the projection of the warp connecting lines 212 on the pressure-bearing warp layer is not overlapped with the projection of the pressure-bearing weft 221 on the pressure-bearing warp layer; likewise, at the interlacing of the weft connecting lines 222 with the warp connecting lines 212, the projection of the weft connecting lines 222 on the pressure-bearing weft layer does not overlap with the projection of the pressure-bearing warp 211 on the pressure-bearing weft layer.

Referring to fig. 7 to 10, further, the strip layer 2 is plain and/or twill woven by using a circular loom, which includes a distribution board and two shuttles, i.e., the circular loom is a two-shuttle loom, and the distribution board includes a first distribution board 4 and a second distribution board 5. The first tap 4 comprises a plurality of first tooth groups, wherein each first tooth group comprises a first solid tooth 41 and three first virtual teeth 42; the second wire dividing disc 5 comprises a number of second tooth groups, wherein each second tooth group comprises three second real teeth and one second imaginary tooth, and a small number of the second tooth groups comprise two second real teeth and two second imaginary teeth.

In this embodiment, taking the woven plain tape blank layer 2 as an example, the two shuttles are provided with thick wefts and thin wefts, respectively. The weaving weft layer 22 is divided by the first distributing wire coil 4, and the shuttle provided with the thick weft is matched with the first distributing wire coil 4 for weaving; the first distributing wire coil 4 picks up one warp thread and drops three warp threads, the picked warp threads are necessarily thin warp threads each time, and thick weft threads penetrate through the picked thin warp threads to be woven to form a woven weft layer 22 formed by weaving an inner-layer belt blank, namely a pressure-bearing weft thread 221 and a weft connecting line 222; it should be noted that the dropped warp includes two thick warps, which are never picked up by the first distribution plate 4, so that the thick warps do not cross with each other, and the pressure-receiving warp 211 does not cross with the pressure-receiving weft 221. The weaving warp layer 21 is divided by a second distributing board 5, and the shuttle provided with the thin weft threads is matched with the second distributing board 5 for weaving; the second distributing board 5 picks up three warps and drops one, two thin warps and one thick warp are bound to be in the three picked up warps each time, the thin warps penetrate the picked up thick warps for weaving, and an outer layer belt blank, namely a woven warp layer 21 formed by weaving the pressure-bearing warps 211 and the warp connecting wires 212 is formed; similarly, the two thin warp threads that are picked up never fall down and therefore do not cross-weave with the thin weft threads. The two belt blanks woven at this point, i.e. the layer of weaving warp threads 21 and the layer of weaving weft threads 22, can be completely separated. The second thread dividing plate 5 has a part of second tooth groups which can only pick up two warps, so that part of thin warps can fall down when weaving the outer layer belt blank, and once the thin warps fall down, the thin warps and the thin wefts are crossed to be woven into the outer layer belt blank; the fallen fine warps are used for weaving the inner-layer belt blank at the same time, and because the time for using the fine warps in the two-layer weaving is different, the two-layer belt blank can not conflict with each other, but the two-layer belt blank can be connected, namely the weaving warp layer 21 and the weaving weft layer 22 are relatively fixed.

In addition to the above embodiments, the circular knitting machine weaves the completed belt blank layer 2, the weft thread layer 22 is weaved in the inner layer of the belt blank, and the warp thread layer 21 is weaved in the outer layer of the belt blank. In this embodiment, the woven tape blank layer 2 is turned over so that the warp knitting layer 21 is on the inner layer and the weft knitting layer 22 is on the outer layer. Warp and weft used in weaving can adopt any high-strength fiber yarn, and corresponding fiber yarns can be selected according to actual needs, so that the finally obtained flat hose can meet various requirements.

Further, according to the above-described weaving method of the belt blank layer 2, the belt blank layer 2 can be woven in two or more layers, not only in one layer of the warp knitting layer 21 and one layer of the weft knitting layer 22, but also in three or more layers; if three layers are woven, the circular weaving machine needs to be provided with at least three shuttles and three branch boards, and the belt blank layer 2 after weaving is sequentially a weaving warp layer 21, a weaving weft layer 22 and a weaving warp layer 21 from inside to outside; and so on.

In another embodiment, the warp connecting lines 212 are woven with the bearing warp 211 to fix a bearing warp layer, and the weft connecting lines 222 are woven with the bearing weft 221 to fix a bearing weft layer, but the warp connecting lines 212 and the weft connecting lines 222 are not woven with each other and are not crossed, which is equivalent to that no crossing is generated between the woven warp layer 21 and the woven weft layer 22; further, the warp knitting layer 21 is bonded to the weft knitting layer 22 to be relatively fixed. In this way, the pressure-bearing warp yarns 211 and the pressure-bearing weft yarns 221 do not intersect with each other, and relative fixation is achieved.

On the basis of the embodiment, the medium conveying layer 1 and the outer protective layer 3 of the utility model are made of elastomer materials, the outer wall of the medium conveying layer 1 is bonded with the inner wall of the belt blank layer 2, and the outer wall of the belt blank layer 2 is bonded with the inner wall of the outer protective layer 3; further, the outer wall of the medium conveying layer 1 is bonded to the weaving warp layer 21, and the outer wall of the weaving weft layer 22 is bonded to the inner wall of the outer protective layer 3.
