Description

High wear-resistant paper forming fabric for high speed paper machine Technical field

The invention belongs to the technical field of papermaking equipment, in particular to a high wear-resistant paper forming forming net for high speed paper machine.

Background technique

The paper forming fabric is an important forming and dewatering structure in the wet end of the paper machine. The existing forming fabric generally comprises three layers of a top layer (also called a paper layer), a bottom layer (also called a machine layer) and a connecting line from top to bottom. Structure, the surface layer is interwoven by the surface and the weft, and the bottom layer is interwoven by the bottom and bottom weft. The connecting line connects the surface layer and the bottom layer. The material of the warp and weft is polyester thread. The layer forming fabric can be applied to the general paper machine to complete the requirements of sheet forming and dewatering tasks, but as the speed of the paper machine continues to increase, the wear resistance of the papermaking net is also put forward higher requirements. The existing paper forming forming network The paper sheet is unevenly formed at high speed, and the service life is low under the condition of ensuring the fiber and filler retention rate of the paper is improved, and the running stability is poor. This is because the existing paper forming fabric, the machine layer (bottom layer) is generally For the 5 comprehensive, 6 or 8 heald structures, the contact area with the contact surface of the paper machine is small, on the other hand, the polyester wire has poor wear resistance, and the consumption is large under high-speed operation and the service life is short.

The Chinese patent with the application number "201410130308.8" discloses a three-layer net of high-speed wide-width 16-mesh seamless paper-making paper. The paper-forming layer (surface layer) is woven by plain weave, and the machine layer (bottom layer) is made of 8 integrated forging. Weaving by interweaving, but the three-layer web forming layer has a relatively large diameter of the warp and weft, a small warp density, and a low fiber support index, which tends to cause uneven and smooth sheet formation during use, and the fiber and filler retention rate of the paper. It is lower, and the machine layer adopts 8 comprehensive forging and weaving interlacing method. The wear resistance can not meet the requirements of high speed paper machine, and the service life is not long enough. Therefore, the development of a forming wire used in a high-speed paper machine has been a technical problem to be solved in the field.

Summary of the invention

In view of the above problems, the present invention provides a high wear-resistant paper forming fabric for a high speed paper machine, which adopts a 1/1 plain weave knitting method, the mesh is uniform and smooth, and the bottom layer is made of a highly wear-resistant 10 heald weave. , greatly improving the wear resistance of the product, the present invention is achieved as follows:

In the present invention, the weft is the weft of the surface layer, the surface warp refers to the warp of the surface layer; the bottom weft refers to the weft of the bottom layer, the bottom warp refers to the warp of the bottom layer; the connecting line refers to the weft of the connecting surface layer and the bottom layer.

The invention provides a high wear-resistant paper-making forming net for high-speed paper machine, comprising a surface layer, a connecting line and a bottom layer three-layer structure, and the surface layer adopts a 1/1 plain weaving method to improve the fiber support index, and the mesh is uniform and smooth, and the mesh is improved. The fiber and filler of the finished paper ensure that the paper sheet is evenly formed, the paper sheet is easily peeled off from the net, and the paper is also smoother; the top layer is laid down in a row, and the connecting wires are woven in pairs, that is, the "one pair of connecting" weft is used to laminate the surface layer with The bottom layer is connected, and the connecting line occupies one-third of the total weft, ensuring that the upper and lower layers are more firmly bonded; the bottom layer is made of highly wear-resistant 10 heald weave, which greatly increases the span of the machine layer weft, the machine layer weft The line float line ratio reaches 9/10, which greatly improves the wear resistance of the forming wire and prolongs the service life of the forming wire.
