Problems solved by technology
The base fabric of the existing paper-making felt is mostly made of warp and weft yarns, and the warp and weft interweaving points lead to a low surface flatness of the base fabric, and most of the warp and weft threads do not have elasticity. Deformation, so that the traces of the fabric are reflected on the paper, forming network marks on the paper surface, affecting the flatness of the paper surface and product quality; and the existing papermaking felt base fabrics are repeatedly pressed under high line pressure conditions, and the base fabrics are easy to embed each other. As a result, the gaps are blocked, which greatly affects the water permeability of the papermaking felt, thereby shortening the service life of the papermaking felt

[0021] Such as figure 1 and combine figure 2 and image 3 As shown, a multi-layer non-interwoven papermaking felt suitable for various paper machines includes a first base layer 1, a second base layer 2, a third base layer 3 and a fourth base layer 4, the The third base network layer 3 is laid on the upper end surface of the fourth base network layer 4, and the second base network layer 2 is laid on the upper end surface of the third base network layer 3, and the first base network layer 1 is laid on the second base network layer. The upper end surface of the second base net layer 2, the first water-absorbing wear-resistant layer 5 is clamped between the first base net layer 1 and the second base net layer 2, and the second base net layer 2 and the third base net A second water-absorbing and wear-resistant layer 6 is sandwiched between the layers 3 , and a third water-absorbing and wear-resistant layer 7 is sandwiched between the third base net layer 3 and the fourth base n...

The invention discloses multi-layer non-interwoven paper making felt suitable for various paper machines. A third base mesh layer is spread on the upper end surface of a fourth base mesh layer, a second base mesh layer is spread on the upper end surface of a third base mesh layer, a first base mesh layer is spread on the upper end surface of the second base mesh layer, a first water-absorbing wear-resistant layer is clamped between the first base mesh layer and the second base mesh layer, a second water-absorbing wear-resistant layer is clamped between the second base mesh layer and the thirdbase mesh layer, and a third water-absorbing wear-resistant layer is clamped between the third base mesh layer and the fourth base mesh layer. The felt provided by the invention has the beneficial effects that the felt is formed by cross pressing of the plurality of base mesh layers, and the wear resistance can be improved; in addition, each base mesh layer is composed of multiple layers of warpsand wefts, and the wear resistance can also be improved; the wear-resistant water-absorbing layers are arranged between adjacent base mesh layers, the wear-resistant water-absorbing layers have wear resistance while having the effect of absorbing water; and the structure form between each base mesh layer and each water-absorbing wear-resistant layer is same, so that the felt has high universalityand is suitable for various paper machines.
Description
technical field [0001] The invention relates to the technical field of papermaking felts, in particular to a multilayer non-interwoven papermaking felts suitable for various paper machines. Background technique [0002] Papermaking felt is a special textile used in the press section of a paper machine. It is mainly used for dehydration, supporting paper sheets, and modifying paper sheets. Among them, dehydration is the key function, and it has the characteristics of changing with the use of time. The surface properties of papermaking felts are directly related to the surface properties of the paper being produced. The base fabric of the existing paper-making felt is mostly made of warp and weft yarns, and the warp and weft interweaving points lead to a low surface flatness of the base fabric, and most of the warp and weft threads do not have elasticity. Deformation, so that the traces of the fabric are reflected on the paper, forming network marks on the paper surface, affe...
