Description of the Invention (1) The present invention relates to a filter paper base fabric for paper machines, although it is not exclusive, it is used with the filter cloth of the press water department of the paper machine There is an association. Traditionally, press felts consist of a woven base fabric that provides adequate strength in the direction of the felt's lotus and provides one or more layers of compressible fibers to the felt, such as by knitting. The manufacturing price of the conventional type of base fabric is very expensive. In addition, due to the existence of knuckles formed at the intersection of the warp and weft yarns forming the base fabric, when the base fabric passes through the press section of the paper machine Marks will be formed on the paper. The main object of the present invention is to provide an alternative to filter fabrics that are traditionally used in the manufacture of paper machine fabrics to avoid or at least partially congenital disadvantages in known structures of conventional fabrics. The invention provides a non-woven base fabric for producing a filter base fabric of a paper machine. The base fabric includes a plurality of layers of synthetic thermoplastic material in a mesh shape, and at least one of the mesh layers includes a direction toward the lotus. Extended endurance yarn. The base fabric preferably includes two layers with different mesh sizes. The present invention also includes a paper-making woven fabric including the aforementioned base fabric, the base fabric and a fibrous batt and / or a slender woven fabric at least on one side of which is fixed on Combined. The present invention will be described in conjunction with several specific embodiments shown in the accompanying drawings and will be further described by way of examples only, in which: FIG. 1. is a perspective view of the appearance of a base fabric pattern made according to the present invention; FIGS. 2. and 3 .Pseudo from the line and M-1 of Figure 1.

Enlarged section of the invention description (); Figure 4. The equivalent of Figure 1. A perspective view showing the changes in the relative arrangement of the mesh layer of another base fabric; and Figure 5. A typical cross-sectional view of a pressed felt combined with the base fabric of the present invention by the appearance method. Please refer to each of the drawings now, and refer to FIG. 1 a. The base fabric used in the production of a pressed felt for paper machines includes a first mesh layer 11 and a second mesh layer 12, the two The network layers are combined in an overlapping configuration. The layer 11 represents a longitudinally extending solid area or rib 13 and a laterally extending solid area 14 to define a rectangular mesh 15 of a first size. The solid area 13 contains yarns 16 to provide in the direction in which the fracturing felt is intended to travel Endurance yarn. The mesh layer 12 has a longitudinally extending solid region or rib 17 and a transversely extending solid region 18, and its outline holes 19 are also rectangular in shape, but of a second size, which is smaller than the mesh holes 15 of the mesh layer 11. On the other hand, according to specific considerations, the longitudinally extending solid area 17 also contains reinforcing yarns 21, but the existence of such yarns is not important. The size of the basic grid layer 1 1 15 is pseudo 5mmXlmm, and the size of the mesh 1 9 of the grid layer 2 is 2mmX0.5mm, the thickness of the two grid layers is 1 · and 1.0mm respectively, and the grid layer is pseudo It is used to diffuse the water present in the woven fabric, so as to reduce the shadow marking of the paper. Of course, the mesh does not have to be rectangular, and * · * This paper means that / t is applicable to China S home standard (CN3) A 4 regulation technology (210 X public loan) -4-81.9.25,000 (please read the back Matters needing attention will be written on this page)-installed · Printed by the Beigong Consumer Cooperative of the Central Standards Bureau of the Ministry of Economic Affairs-Α6 Β6 V. Description of Invention (3) The mesh layer with larger holes can be located above or below another mesh layer. Pseudo-thermoplastic polyurethane, the preferred material for the mesh type (basically, the reference symbol sold by BF Goodrich is 5 8 8 1 0), as far as this article is concerned with the mounting material and its physical durability The reinforcing yarns of the mesh layers 11 and 12 may contain monofilament fiber yarns or multifilament fiber yarns with good binding properties, and basically the diameters of the yarns are 0.5 mm and 0.2 mm, respectively. Although other methods such as powder dispersion technology may be more suitable, the mesh layer is simply manufactured by the method described in GB-A-2202873 and defining the scope of patent application. The two mesh layers are usually joined together by thermal welding of adjacent surfaces in a conventional method. However, it is more convenient to use adhesives or ultrasonic welding in some examples or to provide a fibrous layer until they are overlapped. On the mesh layer, and weave this fiber into and through its mesh layer. It can be found that it is necessary to provide local nodules (protruberances) on one of the adjoining faces of the two mesh layers or on the solid areas of the two adjoining faces, so that if the solid area of one mesh layer covers and thus shields the mesh of the other layer, Provide a profiled surface to the relevant mesh layer and thus ensure the presence of a liquid flow channel. In the second embodiment, please refer to FIG. 4. The longitudinal axis 2 2 of the mesh 1 9 and the longitudinal axis 2 3 of the mesh 15 of the mesh layer 1 are pseudo-inclined. The mesh layers are similar to those shown in Figures 1. to 3. The preferred tilt angle is 45 degrees as shown, however, other deflection angles can be used if desired. ------------------------ Install ------.

Description of the invention (4) The base fabric as shown in the figure, in the production of a paper-making woven fabric, provides support and reinforcement to the needle-punched mat (such as a fiber batt with a conventional pattern and material). If necessary, the wool The layer can be pre-bonded and fixed to the base fabric by thermal fusion or adhesive or ultrasonic fusion or knitting. Usually the fibers in the batt are of any direction, but in some cases, they are oriented in the direction of the length side Sexuality is more appropriate. Alternatively, the fleece layer can be formed on the base fabric by melt blowing technology, where the fibers are pseudo-extruded onto the moving base fabric, and the semi-melted state allows the boundary surface of the fibers to adhere to the base fabric and / Or any pre-supplied fiber layer, according to the special needs of the pressed felt, the fineness of the fiber can be changed during the formation of the batt. Weaving lace, knotted silk or other non-woven fabrics can also be used to make wool layers. The above-mentioned pressed felt is an open-end type, so its ends can be joined, for example, loops are formed at the ends of the coarser mesh layer according to the procedure of GB-A-223 1 838, and the loops are used to accommodate their individual The axis of the finger-like protrusion at the end of the ring hole, and the end of its finer mesh layer is simply joined. The fiber batt, whether formed pseudo-previously or formed in situ by melt blowing, will extend Cross the connecting line and, if necessary, can be cut in the transverse direction of the fracturing felt in an offset configuration with respect to the connecting line as proposed in G BA-223159. However, the batt can also be in an endless form. As mentioned above, the base fabric does not have elbow joints at the junction of the mesh layer and the batt layer, the weight of the provided batt layer can be reduced, and this is the woven fabric forming a woven base fabric to avoid marks needs. __________- w.
