Description of the Invention: [Technical Field of the Invention] The present invention relates to an industrial fabric', particularly to an industrial fabric coated in a geotechnical setting. [Prior Art] In recent years, geotextiles have been widely used in civil engineering, especially in the aftermath of the disaster: the large number of applications and their effects in the repair process have attracted the attention of engineers and technicians. Due to the harsh working environment of geotextile weaving, it is often placed in soil with high humidity, so it must have good hydrolysis resistance, wet mechanical properties, and good water permeability. Referring to FIG. 1 and FIG. 2, taking the common civil engineering weaving i as an example, a plurality of warp yarns 11 and a number of weft yarns 12 are mainly included. In the weaving process, a single warp yarn u and two weft yarns 12 are used to complete one cycle by a plain weave, and a weft yarn 12 is wound up between the warp yarns u. The civil engineering weave woven by this method is strong and strong, and is the most commonly used weave. Since the civil engineering weaving fabric 1 must meet the strength and water permeability, the number, or the strength, or the air gap of each yarn, = whether the above-mentioned civil engineering weaving fabric i can pass the water smoothly. The key to the loss of sand-repellent particles, the warp yarns and wefts, which are orthogonally woven by the plain weave method, will be exposed to water due to the lack of optimum density due to the limitation of the weave and the number of filaments. Poor, or too low density leads to strong:: the celestial environment, the strength and water permeability can not be balanced, but can not satisfy the lack of pleading. 201209238 Refer to Figure 3 _ 4, and take the example of a kind of cracked silk ^• woven fabric 2, which mainly includes several split yarns which are weaved in the warp and weft directions by plain weave or twill weave. 2, each of the split yarns 21 is cut by a film to form a number of split-mold filaments 211 which are not broken from each other, and then subjected to masking treatment to form a crucible. . However, since each mold split and the wire 2n are flat, the strength is lower than that of the monofilament shown in Fig. 而, and more raw materials are required to achieve the required strength, and therefore, under the same strength requirement' The weight of the cracked geotextile woven fabric 2 is obviously heavy, and the cost is high, and the manpower requirement during construction is also high. SUMMARY OF THE INVENTION Therefore, (4) of the present invention provides an industrial fabric which can achieve both strength and water permeability. The industrial fabric of the present invention comprises a plurality of yarns. These yarns are weft-woven in the warp and weft directions by twill weave, so that any cross section of the yarn in the warp direction, the weft direction and the eve of the yarn is included in each thread. And the fineness of each monofilament fiber is limited to 5 〇 Danny 〇〇 5 〇〇 〇 〇 〇 〇 〇 〇 〇 〇 〇 〇 〇 〇 〇 〇 〇 〇 〇 〇 〇 〇 〇 〇 〇 〇 〇 〇 〇 〇 〇 〇 〇 〇 〇 〇 〇 〇 〇 〇 In the case of sufficient strength, 'has still maintained good water permeability. The above and other technical contents, features, and advantages of the present invention will be apparent from the following detailed description of the preferred embodiments. 201209238 Referring to Figures 5, 6' and 7', a first preferred embodiment of the industrial fabric 3 of the present invention comprises a plurality of yarns, and the yarns are divided into a plurality of multifilament yarns 31, and a plurality of monofilaments. Yarn 32. The multifilament yarns 31 and the equal number of monofilament yarns 32 are respectively a high molecular polymer in the preferred embodiment, such as polypropylene (p〇lypr〇pylene, pp), I. Alcohol g (p〇lyethyie, ne terephthalate, PET.), polyethylene (Polyethylene, PE). Each of the multifilament yarns 3 is composed of a plurality of monofilament fibers 311, and the fineness of each of the monofilament fibers is limited to 50 denier to 500 denier. Each monofilament yarn 32 is a monofilament fiber with a fineness of 501 Danny ~ 2 〇〇〇 Danny. When weaving, the multifilament yarns 3丨 and the monofilament yarns 32 are weft-woven in the warp and weft directions by twill weave, and the weaves may be left-slanted or right-slanted, and the twill weave may be n. One of the /1 twill ~n/7 twill, the aforementioned η value is bounded by 2 to 7, such as 2/2, 3/2, 4/2, 5/1, 6/1, 3/7, etc. to 2/ 1 twill as an example, that is, there are two warp yarns (multifilament yarn 31 or monofilament yarn, thread 32) on top of a weft yarn (multifilament yarn 3) or monofilament yarn Line 32) is woven underneath. It is important to follow the warp and weft directions: where the ^-direction is a cross-section of each of the monofilament fibers 1' or 5-60 of the monofilament yarns 32. Thereby, the multifilament yarns 31 and the monofilament yarns 32 are comprised of the following seven variations: Columns ... show that the fabric 3 is made of the warp yarns and the weft yarns The aligned multifilament yarns 3 are interwoven in a 2/1 twill weave. 201209238 As shown in FIG. 8 to circle 10, the industrial, arranged multifilament yarns 31, and the weft yarns 32 are 2/one: "]/. Weft, warp (4) These sheets are interwoven by 2/1 twill weave. The row is as shown in the figure == 'The industrial fabric 3 is made of the multifilament yarns which are interlaced by the twill weaves respectively. The line 31' is arranged in the form of =/4~Fig. 'The industrial fabric 3 is made up of the warp yarns 31 along the warp yarns, respectively, in the weft direction, the warp direction, and the line 32, using 2/ 1 Twill weave is interwoven. Μ广如二17~19, 'the industrial fabric 3 is composed of the monofilament yarns, the thread 32, and the multifilament yarns 31 arranged in the weft direction and the warp direction, respectively. Interwoven with 2/1 twill weave. 6. As shown in Fig. 20 to Fig. 22, the industrial fabric 3 is made of the monofilament yarns 32 arranged in the warp direction and the multifilament yarns 31' arranged in the weft direction and the warp direction, respectively. /1 Twill weave is interwoven. 7. As shown in FIG. 23 to FIG. 25, the industrial fabric 3 is composed of the multifilament yarns 3 分别 arranged in the warp direction and the weft direction, and the monofilament yarns respectively arranged in the weft direction and the warp direction. 32, interwoven with 2/1 twill weave. Thus, since the industrial fabric 3 is twill weave, a large number of multifilament yarns 31 or monofilament yarns 32 are used for interlacing, and each multifilament yarn 31 is made of a high number of monofilament fibers. The bundles are bundled together, so that not only can the twill weave be less than the firmness of the plain weave, but the fabric strength of the industrial fabric 3 reaches about S0KN/M, and a large amount of gaps between the fibers 311 can be made. The industrial fabric 3 has a water permeability of 900 liters 201209238 / Μ 2, compared with the water permeability U1 liter / M2 of the general 25KN industrial fabric, or the water permeability of the general 45KN industrial fabric is 270 liter / Μ 2, the water permeability is significantly improved South is 330%~800%. Referring to Figures 26, 27, and 28, there is shown a second preferred embodiment of the present invention which is substantially identical to the first preferred embodiment. The difference is that the industrial fabric 3 comprises a 2/1 twill weave. The method is a plurality of multifilament yarns 31 which are woven in the warp direction and the weft direction. Each multifilament yarn 3丨 also contains a plurality of monofilament fibers 311. The fineness of each monofilament fiber 311 is limited to 5 〇 Danny ~ 5 丹 Danny. It is also important that any section extending in one of the warp direction and the weft direction contains 2 〇〇 2 〇〇〇 of monofilament fibers per inch. It is also possible to use twill weave in combination with a high unit number of monofilament fibers and the gaps present between them to maintain good water permeability properties with sufficient strength. Referring to Figures 29 and 30, the industrial fabric 3 is formed by interlacing the multifilament yarns 31 arranged in the weft direction and the warp direction by a 3/1 twill weave. As can be seen from the above, the industrial fabric of the present invention has the following advantages and effects: The present invention adopts a twill weave method and defines a monofilament yarn of 3 U, or 5_6 purlin, which contains a fine-toilet strip per inch. Line %, which does not have the required cloth strength 'and a large amount of gaps between the monofilament fibers 311', retains good water permeability, and satisfies the use demand in the case of both strength and water permeability. The convenience and practicability of the use can be improved. 201209238 However, the above description is only a preferred embodiment of the present invention, and can be limited thereto; t the scope of the present invention is the invention according to the invention: scope and invention description The simple equivalent changes and modifications made by the content are within the scope of the invention.
