Background

In the trades such as the electric industry, cement manufacture, need set up ventilative board as ventilative layer in the cell body when carrying out air chute transport and horizontal transport to cement, aluminium oxide, current ventilative board includes upper, middle, lower three-layer fabric layer, wherein the upper strata is the twill, the lower floor is the heavy plain weave of latitude, the middle level is the twill, upper, middle, lower three-layer fabric layer is connected fixedly through four connecting wires, when the connecting wire sews up, four connecting wires divide into two sets ofly, a set of comprises connecting wire 1 and connecting wire two 2, sew up upper strata and medial woof 8, another group comprises connecting wire three 3 and connecting wire four 4, sew up lower floor and medial woof 8, two sets of connecting wires interval sew up the woof of upper strata and lower floor simultaneously when sewing up upper strata and medial woof and lower floor and medial woof respectively. Adopt above-mentioned structure, because upper strata and middle level are the twill, therefore, the air-permeable plate easily inclines to one side of air-permeable plate in the use, produce and warp, make the bleeder vent receive the jam, in addition, owing to adopt four connecting wires to connect the three-layer fabric, and every two-layer fabric is connected fixedly by a connecting wire, three-layer about going up by third and fourth line circulation again, make technology complicated when making, especially because it encircles to have the endless connecting wire between each layer, the elasticity is difficult to accomplish to the elasticity unanimity for the elasticity of many connecting wires, thereby make the elasticity between each layer inconsistent, easily cause the mutual movement between each layer, make the production looks mutual friction between each layer, the fracture of connecting wire is easily caused to the friction between each layer, thereby reduce the life-span of air-permeable plate.

Disclosure of Invention

The utility model aims to provide a ventilative board to the ventilative board manufacturing process of prior art structure is complicated, produce between each layer relative slip and take place the friction and easily make the connecting wire fracture reduce the not enough in the life-span of ventilative board, thereby provide a ventilative board.

The invention aims to be realized by the following technical scheme:

a multi-layer breathable plate comprises a plurality of layers of fabrics, wherein each layer of fabric is a plain weave fabric with a consistent weave structure, each weave of each layer of plain weave fabric is in up-down correspondence in circulation and comprises two sewing threads with opposite directions, and a group of adjacent weft yarns which are arranged in up-down opposition are surrounded and locked by the two sewing threads with opposite directions;

the plain weave is 1/1 plain weave, 2/2 plain weave or 3/3 plain weave;

the breathable plate comprises 3-5 layers of fabric;

warp yarns and weft yarns of the fabric are basalt continuous fiber twisted yarns;

the sewing thread passes between every two adjacent warp yarns;

the interval between two adjacent seaming lines is 2-3 warp yarns.

Adopt the utility model discloses the fabric of structure, each layer all adopts plain weave, the homogeneity is good, be difficult for the off tracking, wear to the opposite side of fabric from one side of fabric by a line, the homogeneity of line is good during the threading, good stability, the line elasticity is unanimous, make the stability of each layer of fabric better, additionally, adopt a line at a threading direction, make weaving simple process, it is easier to weave, a line is connected to the multilayer together the back with the rigidity of each warp and woof firmly, the friction between each other has been reduced, the life-span of yarn has obtained obvious height, ventilative board's life-span is corresponding to have obtained the improvement, same organizational structure, same yarn, the life-span has prolonged 25-30%.

1-warp yarns; 2-a weft yarn; 3-suture one; 4-suture line two.

Detailed Description

The gas permeable plate of the present invention will now be further described with reference to the accompanying drawings and specific embodiments.

The invention provides a multilayer breathable plate, which comprises at least two layers of fabrics, wherein the upper layer and the lower layer of each layer of fabric are arranged, each layer is a plain weave with the same weave, the layers are interwoven and sewn together through a suture line, each weave of the upper layer of fabric and the lower layer of fabric corresponds in circulation, namely, warp yarns and weft yarns of the upper layer and the lower layer of fabric are mutually overlapped, the thread lines are opposite, gaps and gaps are opposite, the threading directions of the two suture lines are opposite and consistent, one suture line is also called a suture line I3, penetrates through the lower layer of fabric from the upper layer of fabric to the lower layer of fabric from the adjacent two weft yarns 2, bypasses the weft yarns of the second row, penetrates through the upper layer of fabric from the lower layer of fabric from the second row to the third row of fabric from the lower layer to the upper layer of fabric, and is threaded in a reciprocating manner in turn, and the other suture line is also called a suture line II 4 and the same as the threading direction of the suture line I3, and can also be different. A sewing line can be arranged between two adjacent warp yarns 1 or a sewing line can be arranged by spacing more than two warp yarns. But generally no more than 3 warp yarns are not over spaced to prevent slackening.

In the utility model, 3-5 layers of fabrics are preferably arranged, so that the thickness of the fabrics can reach 6-8mm, and the air permeable plate has certain thickness to provide better supporting force. The multilayer fabrics are tightly and firmly connected together by interweaving two sewing threads to form the stiff and thick breathable plate.

The fabric of the utility model can be 1/1 plain fabric, 2/2 plain fabric and 3/3 plain fabric. Preferably, a 1/1 plain weave is used, so that the air-permeable sheet has the highest porosity and relatively the best air permeability.

The basalt continuous fiber twisted yarn is preferably adopted for weaving, so that the strength and the high temperature resistance of the air permeable plate can be improved, the air permeable plate can work under the working condition of exceeding 300 ℃, and the blank of the air permeable plate resistant to the high temperature of 300 ℃ is filled.

The air permeable plate adopting the structure of the utility model has the characteristics of strong force, good air permeability, stable size and no deformation after long-term use.

Adopt the utility model discloses the ventilative board of structure, each tissue circulation of upper and lower floor is corresponding in every layer of plain weave fabric, therefore, there is the hole many between yarn and yarn, the gas permeability is good, because adopt two stylolite from the bottom to pass from every two adjacent warp/woofs with opposite direction from the top to the bottom or from the top to the bottom, consequently, it can the reinforce to close the cable of fabric yarn, difficult emergence mutual displacement between upper and lower layer fabric, and the fabric adopts plain weave, consequently, each layer fabric is all indeformable, difficult production relative removal between each layer fabric, difficult phenomenon of taking place looks mutual friction, consequently, stylolite and yarn are difficult for wearing and tearing, firm in connection is lasting between each layer, ventilative board is not fragile.
