Problems solved by technology

[0004] The inventors of the present invention have found in the long-term research process that the existing high-speed household paper special forming wire has a low fiber support index on the paper surface, resulting in obvious network marks on the surface of the finished household paper product, leaving fibers and fillers in the household paper. The disadvantage of low deposition rate is not suitable for the needs of high-speed tissue paper machines

Embodiment 1

[0021] The warp thread of the paper layer adopts polyester monofilament with a diameter of 0.125mm, the weft thread of the paper layer adopts polyester monofilament with a diameter of 0.13mm, and the weft thread of the middle connecting layer adopts polyester monofilament or nylon monofilament with a diameter of 0.12mm. The layer warp adopts polyester monofilament with a diameter of 0.125mm, and the machine layer weft adopts a polyester monofilament with a diameter of 0.25mm. The method in GB / T 24290-2009 "Measurement Method for Paper Forming Wire and Drying Wire" is used for the embodiment The special forming wire for high-speed household paper in 1 was tested for performance, and the test results are shown in Table 1 below.

Embodiment 2

[0023] The warp thread of the paper layer adopts polyester monofilament with a diameter of 0.125mm, the weft thread of the paper layer adopts polyester monofilament with a diameter of 0.13mm, and the weft thread of the intermediate connection layer adopts polyester monofilament or nylon monofilament with a diameter of 0.13mm. The polyester monofilament with a diameter of 0.125mm is used for the warp of the layer, and the polyester monofilament with a diameter of 0.25mm is used for the weft of the machine layer. The above-mentioned high-speed The performance test of the forming wire specially used for household paper is carried out, and the test results are shown in Table 1 below.

Abstract

The invention discloses a forming mesh specially used for high-speed household paper and papermaking equipment. The forming mesh comprises a paper-forming layer, an intermediate connection layer and a machine layer, wherein the paper-forming layer is formed by weaving paper-forming layer warps and paper-forming layer wefts according to a 4-satin weaving method; and the machine layer is formed by weaving machine layer warps and machine layer wefts according to a four-satin weaving method. By virtue of the way, the implementation way provided by the invention can improve fiber support index of a paper surface.

Description

technical field [0001] The invention relates to the field of papermaking, in particular to a special forming wire for high-speed household paper and papermaking equipment. Background technique [0002] The forming wire is an important forming and dewatering material in the wet end of the paper machine. The paper machine for high-speed household paper has special requirements for the forming wire. [0003] The paper machine for high-speed household paper has a short wire table, and the forming wire is required to be dehydrated quickly; at the same time, because the household paper sheet is thin and the grammage is low, the fiber support index of the forming wire is required to be high, and the paper has no network marks; Paper is soft and fluffy. [0004] The inventors of the present invention have found in the long-term research process that the existing high-speed household paper special forming wire has a low fiber support index on the paper surface, resulting in obvious ...
