Embodiment approach 1
[0037] Such as Figure 1 to Figure 3 As shown, the first embodiment of the present invention provides a kind of anti-stretching and anti-stretching high-performance industrial filter cloth, such as an industrial filter cloth 1, which is mainly composed of warp yarns, surface weft yarns for forming the filter cloth surface layer 11, It is composed of inner weft yarns used to form the filter cloth layer 13 and multiple groups of weft yarns used to form the filter cloth middle layer 12 .
[0038] warp (reference figure 2 The warp yarn 21, the warp yarn 22 and the warp yarn 23) are respectively combined with the surface layer weft yarn, the middle layer weft yarn and the inner layer weft yarn (refer to figure 2 The surface layer weft yarn 111, the middle layer weft yarn 121 and the inner layer weft yarn 131) are interwoven to form the filter cloth surface layer 11, the filter cloth middle layer 12 and the filter cloth layer 13.
[0039] Wherein, the warp yarn shuttles back and...
Embodiment approach 2
[0065] The second embodiment of the present invention provides an anti-stretch and anti-stretch high-performance industrial filter cloth, which is roughly the same as the above-mentioned embodiment, except that, as image 3 and Figure 4 As shown, the middle layer in this embodiment is a two-layer or multi-layer spacer structure, so as to match different types of filter components 15 to meet the filtering requirements of different filtrates. Wherein, each warp yarn can be crossed and exchanged multiple times at the intervals of the tubular channels 14 in the middle layer according to the above-mentioned cycle rule, so as to form a double-layer and multi-layer spaced structure.
[0066] In addition, when the middle layer has a spaced structure of more than two layers; among them, the materials of the filter components arranged in the tubular channels in the adjacent two layers are different, therefore, when the liquid is filtered through the industrial filter cloth, different l...
Embodiment approach 3
[0072] The third embodiment of the present invention provides an anti-stretch and anti-stretch high-performance industrial filter cloth, which is a preferred embodiment of the first or second embodiment above.
[0073] In this embodiment, a single-axis dobby loom is used for weaving, wherein the density of warp and weft yarns is woven according to the parameters in Table 1 below to obtain a gray cloth, and then the gray cloth is refined, heat-set, and dried, and then the post-finishing processing is performed, for example Carry out calendering treatment under the pressure of 1.5MPa to obtain the finished filter cloth. Here, it should be noted that the refining temperature in this example is preferably 90°C. The heat-setting temperature is preferably 130°C to 180°C. The average pore diameter of the filter holes of the industrial filter cloth is between 1-20um; the warp and weft density is preferably 90-150 threads / inch, and the linear density of the warp and weft yarns is pref...
