AI Technical Summary

Problems solved by technology

The diameters of the warp threads forming the paper surface layer and the warp threads contacting the bottom layer are different. In the same warping, it can be woven into a three-layer papermaking fabric in which the warp threads of the paper surface layer are separated from the warp threads contacting the bottom layer. The bottom warp becomes a two-layer or two-and-a-half-layer paper-making fabric with the same number of warps, so that more types of products cannot be provided to meet the needs of more different paper factories with the same number of production equipment. If it is necessary to increase the contact with the bottom weft must be increased at the same time as the diameter of the warp that contacts the bottom layer

[0047] exist figure 1 and figure 2 A 20-shed three-layer forming wire 801 is shown in the figure, and a basic cycle structure of the forming wire 801 is shown in the figure, from figure 1 As can be seen in the figure, the paper surface layer of the three-layer forming wire 801 has 10 surface warps 12, 14, 16, 18, 20, 22, 24, 26, 28, 30, and 10 in each repeated cycle Surface weft 91-100 and 20 three-dimensional composite yarns 61-80 are interwoven into the paper surface layer. They are interwoven with each other in plain weave. For example, surface weft 91-100 passes through the top of surface warp 12 and then passes Below the surface warp 14, then through the top of the surface warp 16, then through the bottom of the surface warp 18, and so on until passing through the bottom of the surface warp 30.

[0048] figure 2 The structure of the bottom layer of the forming net 801 is shown, and each repeated cycle organization includes 10 base warps 11, 13, 15, 17, 19, 21, 23, 25...

[0056] Depend on Figure 4 - Figure 6 shows a 20-shed three-layer forming fabric 802 according to the second embodiment of the present invention. The forming mesh 802 is included on the weaving texture with figure 1 The embodiment shown is the same as the paper face layer. Shown in the figure is that this forming mesh 802 contacts a basic circulation structure of the bottom layer, from Figure 4 As can be seen in the figure, the contact bottom layer of the three-layer forming net 802 has 10 base wefts 151 with 10 base longitudes 111, 113, 115, 117, 119, 121, 123, 125, 127, 129 and 10 base latitudes for each repeated cycle. -160, the forming net 802 also includes 10 pairs of three-dimensional composite yarns 161 and 162-179 and 180.

Abstract

The invention discloses a forming net fabric for papermaking, the structure of which includes a yarn system forming the paper surface layer and a yarn system group contacting the bottom layer; A plurality of three-dimensional composite yarns, the three-dimensional composite yarns are interwoven with the paper-forming surface layer yarns and the contact bottom yarns perpendicular to the extending direction; it is composed of a paper-forming surface layer interweaving part and a non-paper-forming surface layer interweaving part; the three-dimensional composite yarn The interwoven portion of the non-paper-forming top yarns of the thread, which is located under the paper-forming top yarns and passes through 1 or 2 contacting the underside of the bottom yarns. The three-dimensional composite yarn in the paper-making forming wire of the present invention is on the same plane as the top of the paper-forming surface layer and the top of the weft thread of the paper-forming surface layer, and has uniformly arranged mesh holes. The top warp and the bottom warp can be substituted for each other, which can provide more types of products to meet the various needs of more different paper mills, and reduce the production cost of products.

Description

field of invention [0001] This invention relates to papermaking fabrics, commonly known as papermaking forming wires. Background technique [0002] In the paper industry, pulp is turned into paper through a series of equipment and processes, among which the fourdrinier paper machine is the main equipment of the paper industry. The pulp box is sprayed onto the surface of the forming wire. The forming wire is an endless mesh belt woven from polymer materials. The rollers run circularly at a certain speed. Various dewatering devices on the wire table are located on the lower side of the forming wire contacting the bottom layer, such as water suction boxes and wipers. During the belt running, the moisture and other liquids in the pulp are filtered, and the raw material fibers in the pulp are separated from the water medium to form a wet paper web on the paper surface layer of the forming wire, and enter it through the transfer device after the vacuum couch roll squeeze area. ...
