Example Embodiment

[0021]In order to make the above objects, features, and advantages of the present invention, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0022]The specific details are set forth in the following description to fully understand the invention. However, the present invention can be implemented in a variety of other means described herein, and those skilled in the art can do a similar promotion without violating the connotation of the present invention. The present invention therefore is not limited by the specific embodiments disclosed below.

[0023]In the existing papermaking technique, the paper product embossed is multifodally formed by pressing the roller, first manufacturing a planar paper product, then press the pressure roll or the pair of paper products, stretch, due to planar paper The thickness is already constitutive, forcibly squeezing, and the stretching can only be tered, resulting in a brok...

Abstract

The invention discloses a forming net capable of producing three-dimensional patterned paper, and the forming net comprises a plurality of weft yarns, wherein each weft yarn is straight, the plurality of weft yarns are sequentially arranged from back to front to form a weft yarn plane, weft yarn gaps in the front-back direction are arranged between adjacent weft yarns, and the distances of the weft yarn gaps are equal; a plurality of warp yarns, wherein the plurality of warp yarns are sequentially arranged from left to right, each warp yarn penetrates from a first side to a second side of a weft yarn plane and then penetrates back to the first side, and at least one part of each warp yarn simultaneously spans at least two continuous weft yarns; warp gaps in the left-right direction are formed between the adjacent warps, and the distances of the warp gaps are equal; and the warps above the plane of the wefts form a convex target pattern. The invention further discloses a papermaking filter screen and a papermaking machine. Raw paper of household paper produced by using the forming net has the following advantages: 1, the bulk of the paper is improved by more than 30%; 2, the softness of the paper is also improved to the same degree; 3, the special pattern of the net part is provided, so that the market identification rate is high.

Description

technical field [0001] The invention relates to the field of papermaking equipment, in particular to a forming net capable of producing three-dimensional patterned paper, a papermaking filter screen for papermaking, and a papermaking machine. Background technique [0002] In the existing papermaking technology, the embossing on the paper product is usually formed by double-roll extrusion. Firstly, the flat paper product is produced, and then the paper product is squeezed and stretched by the pressing roller or the double-roller. The thickness has already been set during production, and forced extrusion and stretching can only tear the paper product, causing the fiber of the paper product to break and reduce the quality. In addition, the bulk of the paper produced by the prior art (the bulk of the paper is another indicator of the density of the paper, it refers to the volume of a certain weight of paper, which is the reciprocal of the tightness in value.) is relatively low ...
