It is usually the middle layer in the filter felt or filter material, providing support and skeleton structure for the filter layer. It mainly serves as the support layer of the filter material.

[0012] The reinforcing support layer includes a plurality of horizontal lines and vertical lines arranged at intervals, and the horizontal lines and vertical lines are connected by interlaced weaving.

[0013] Preferably, a plurality of reinforcement holes are arranged between adjacent plurality of the horizontal lines and the vertical lines, and the plurality of reinforcement holes are filled with filter particles, and the filter particles are activated carbon particles.

[0014] Preferably, the surface layer and the air permeable filter layer are respectively a polyphenylene sulfide ultrafine fiber layer and a polyphenylene sulfide short fiber layer.

[0015] Preferably, a plurality of support strips are arranged at intervals between the surface layer, the air-permeable filter layer, the reinforcing support layer and the base fabric layer.

[0016] Furthermore, the antistatic layer is formed by interweaving polyester filaments and metal fiber filaments.

[0017] Preferably, the outer woven sleeve of the filter base cloth is provided with side wrapping strips.

[0027] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0028] The utility model embodiment discloses a composite blended filtering base cloth.

[0029] Example 1

[0030] The utility model provides Figure 1-3 A composite blended filter base fabric shown includes a filter base fabric 1, the filter base fabric 1 includes a surface layer 2, an air permeable filter layer 3, an antistatic layer 10, a reinforcing support layer 4 and a base fabric layer 5, the base fabric layer 5 is a polytetrafluoroethylene vinyl fabric layer, the surface layer 2 and the air permeable filter layer 3 are respectively a polyphenylene sulfide ultrafine fiber layer and a polyphenylene sulfide short fiber layer, and the surface layer 2, the air permeable filter layer 3, the antistatic layer 10, the reinforcing support layer 4 and the base fabric layer 5 are blended and formed;

[0031] The reinforced support layer 4 includes a plurality of spaced-apart horizontal lines 6 and vertical lines 7, which are woven and connected in an interlaced manner. A plurality of arranged reinforcement holes 8 are provided between adjacent horizontal lines 6 and vertical lines 7, and the plurality of reinforcement holes 8 are filled with filter particles 9, which are activated carbon particles.

[0032] Before the base fabric is prepared, the reinforcing support layer 4 is arranged and the placement of the filter particles 9 is ensured, and then the surface layer 2, the breathable filter layer 3, the reinforcing support layer 4, the antistatic layer 10 and the base fabric layer 5 are blended and woven. During the use of the base fabric, since the surface layer 2 and the breathable filter layer 3 adopt the polyphenylene sulfide ultrafine fiber layer and the polyphenylene sulfide short fiber layer, the base fabric has excellent filtering performance and temperature resistance, and can effectively intercept tiny particles in the air. At the same time, the polyphenylene sulfide short fiber layer provides good air permeability and structural support. In addition, the arrangement of multiple horizontal lines 6 and vertical lines 7 not only improves the structural strength of the filter base fabric, but also increases the adsorption capacity of impurities by arranging the filter particles 9, further improving the filtering effect of the base fabric. At the same time, the polytetrafluoroethylene based fabric layer is used as the bottom layer, providing excellent wear resistance and corrosion resistance.

[0033] Example 2

[0034] Embodiment 2 is based on embodiment 1 to further improve the use strength of the base fabric. Figure 1-2 As shown, the antistatic layer 10 is made of polyester filaments and metal fiber yarns interwoven, and a plurality of spaced support strips 11 are provided between the surface layer 2, the breathable filter layer 3, the reinforcing support layer 4 and the base fabric layer 5, and the outer woven sleeve of the filter base fabric 1 is provided with side wrapping strips 12.

[0035] The antistatic layer 10 is made of polyester filaments and metal fiber yarns interwoven, has good antistatic properties, and can effectively prevent safety accidents caused by static sparks. The setting of multiple support strips 11 can cooperate with the reinforced support layer 4 to provide auxiliary support for the base cloth. In addition, with the setting of the side wrapping strips 12, the outer side of the base cloth can be wrapped and protected after the multi-layer fabrics are blended, and the side of the base cloth can be prevented from being derailed, thereby improving the stability of the base cloth.

[0036] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
