Detailed Description
The following description of the technical solutions in the embodiments of the present application will be made clearly and completely with reference to the drawings in the embodiments of the present application, and it is apparent that the described embodiments are only some embodiments of the present application, but not all embodiments. All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present disclosure.
Referring to fig. 1, fig. 1 is a schematic structural view of one embodiment of a single-warp, flat-filament drying web of the present application, the single-warp, flat-filament drying web comprising: a first system weft 10, a second system weft 20 and a system warp 30.
The system warp 30 interweaves with the first system weft 10 to form a paper ply 100 of the single warp flat wire dryer web, and the system warp 30 interweaves with the second system weft 20 to form a machine ply 200 of the single warp flat wire dryer web.
The system warp 30 comprises a plurality of warp yarns, the first system weft 10 comprises a plurality of weft yarns, and the second system weft 20 comprises a plurality of weft yarns. The system warp 30 and the first system weft 10 are interwoven according to a certain texture to form a paper layer 100, and the system warp 30 and the second system weft 20 are interwoven according to a certain texture to form a machine layer 200.
Specifically, the paper forming layer 100 is a paper pasting surface, the machine layer 200 is a cylinder pasting surface, and the system warp 30 is vertically inserted between the paper forming layer 100 and the machine layer 200, namely, the single-warp flat wire drying net in the embodiment is of a single system warp structure, so that the contact mode of the single-warp flat wire drying net and paper is point contact, no net mark exists, the paper forming effect is better, the requirement of low gram weight paper on the paper surface can be met, meanwhile, the single-warp flat wire drying net is compact in structure, and particles such as rosin and latex in the paper are not easy to adsorb on the surface of the single-warp flat wire drying net, so that the single-warp flat wire drying net is easy to clean, and the service life of the single-warp flat wire drying net is indirectly prolonged.
Alternatively, the system warp 30 and the first system weft 10 are interwoven by a satin weaving method to form the paper layer 100 of the single-warp flat-wire drying net, and the system warp 30 and the second system weft 20 are interwoven by a satin weaving method to form the machine layer 200 of the single-warp flat-wire drying net.
Specifically, the satin knitting method is different from the Ping Zhibian knitting method and the twill knitting method, the satin weave warp (or weft) formed by the satin knitting method has longer floats, has fewer interweaving points, forms oblique lines, is not continuous, has regular and uniform mutual interval distances, and has soft texture, smooth silk surface and better luster, and compared with the plain weave formed by the plain knitting method and the twill weave formed by the twill knitting method, the satin weave formed by the satin knitting method is more noble and gorgeous.
Alternatively, to ensure that the single warp flat wire dryer web does not retract laterally and has good stability, the diameter of the first system weft 10 is greater than the diameter of the second system weft 30. In an application scenario, the diameter of the first system weft thread 10 is 0.4-0.5mm, e.g., 0.4mm, 0.45mm, 0.5mm, etc., greater than the diameter of the second system weft thread 30. By setting the diameter of the first system weft 10 to be larger than the diameter of the second system weft 30, that is, the first system weft 10 is thicker than the second system weft 20, the longitudinal and transverse stability of the single-warp flat wire drying net is enhanced, and the single-warp flat wire drying net is not easy to deform when running on a paper machine, so that the service life of the single-warp flat wire drying net can be prolonged.
Alternatively, the system warp 30 is rectangular in cross-section and the first system weft 10 and the second system weft 20 are circular in cross-section.
The cross section of the system warp 30 is rectangular, which can increase the contact area of the single warp flat wire drying wire with the paper sheet.
Alternatively, the diameter of the first system weft thread 10 is 0.80-1.20mm, the diameter of the second system weft thread 20 is 0.30-0.80mm, for example, the diameter of the first system weft thread 10 is set to 0.80mm, 0.90mm, 1.00mm, 1.2mm, etc., and the diameter of the second system weft thread 20 is set to 0.30mm, 0.50mm, 0.6mm, 0.80mm, etc., according to different paper type requirements.
Alternatively, the ratio of the number of first system wefts 10 to the number of second system wefts 20 is 1:1, that is to say that for a single warp flat wire dryer fabric the number of first system wefts 10 and the number of second system wefts 20 is the same.
Optionally, the single-warp flat filament drying net includes a plurality of minimum organization units, the minimum organization units are formed by 4 warps and 8 wefts, and in an application scenario, when the ratio of the number of the first system wefts 10 to the number of the second system wefts 20 is 1:1, the number of the first system wefts 10 is 4 and the number of the second system wefts 20 is also 4 in the 8 wefts of the minimum organization units.
Referring to fig. 2 and 3, fig. 2 is a schematic diagram of weaving patterns of an embodiment of the minimum organization unit, and fig. 3 is a schematic diagram of a structure of an embodiment of weft distribution weaving of the minimum organization unit in fig. 2.
In fig. 2, the unfilled square represents the weft yarn below the warp yarn, the filled square represents the weft yarn above the warp yarn, and 2 weft yarns from top to bottom are circulated, the first weft yarn being the first system weft yarn 10 and the second weft yarn being the second system weft yarn 20.
Alternatively, the single warp flat wire drying net is formed by interweaving polyester monofilaments or nylon monofilaments with 16 heald frames. For example, the system warp 30 is a highly hydrolysis resistant polyester flat yarn, the first system weft 10 and the second system weft 20 are highly hydrolysis resistant polyester round yarns, and the hydrolysis resistance of the single warp flat yarn drying net can be improved by selecting a highly hydrolysis resistant polyester material.
The single-warp flat wire dryer wire of the present application will be further described in connection with two specific examples.
The following two embodiments are all woven by adopting 16 heald frames, the system warp 30 and the first system weft 10 are interwoven to form a paper layer 100, the system warp 30 and the second system weft 20 are interwoven to form a machine layer 200, and the number ratio of the first system weft 10 to the second system weft 20 is 1:1.
Example 1: the warp 30 uses flat filaments with a dimension of 0.31 x 0.62mm, the first system weft 10 uses round filaments with a diameter of 0.80mm, and the second system weft 20 uses round filaments with a diameter of 0.30 mm.
Example 2: the warp 30 uses flat filaments with a dimension of 0.31 x 0.62mm, the first system weft 10 uses round filaments with a diameter of 0.90mm, and the second system weft 20 uses round filaments with a diameter of 0.80mm.
The single-pass flat wire drying wire obtained in examples 1 and 2 was tested by the method of GB/T24290-2009 method for measuring paper forming wire and drying wire, and the single-pass flat wire drying wire performance was measured as shown in Table 1 below.

| Tensile strength | 1826N/cm | 1880N/cm |
| Air permeability | 121CFM | 170CFM |
As can be seen from table 1 above, the single-pass flat filament drying net provided by the present application is thinner, stronger in tensile ability, and smaller in air permeability, whereas in general, the thinner the single-pass flat filament drying net is, the faster it is dehydrated and stronger in drying ability; the stronger the tensile capacity is, the stronger the dimensional stability of the single-warp flat filament drying net is, the stronger the wear resistance is, and the longer the service life is; the smaller the air permeability is, the larger the density of the single-warp flat yarn drying net is, the larger the contact area between the single-warp flat yarn drying net and paper is, and the produced paper has better flatness. Therefore, the single-warp flat yarn drying net in the application has the advantages of strong stability, strong drying capacity, large contact area with paper, capability of reducing net marks, good wear resistance and long service life.
