Description

This application was filed with the Chinese Patent Office on August 16, 2019, claiming the priority of the Chinese patent application with the application number 201910760175.5 and the invention name "Tissue and Manufacturing Method", all of which. By incorporating the contents of, it is combined with this application.

The present invention relates to a tissue and a method for producing the same, and specifically, is a method for producing a multilayer product.

Tissues are generally made from natural, non-polluting raw materials such as wood pulp, bamboo pulp, cotton pulp and straw pulp, and if classified according to application, facial tissue, napkin base paper, paper handkerchiefs, wet It includes tissue, paper towels, kitchen paper, etc., and can be divided into single layer, two layers, and multiple layers according to the structure of the tissue. Therefore, each layer of pulp is adhered by embossing, which affects the physical performance such as tissue thickness, tactile sensation (surface flexibility), and absorbency (fluffy and flexible) during the embossing process. Is a key point in papermaking technology that affects tissue performance.

The structure of knurled toilet paper currently on the market is mainly produced by the knurling process and the adhesion of the knurled toilet paper (embossed composite structure). Conventional knurled toilet paper is mainly 2-pass knurled, but conventional known disclosed 3-pass knurled toilet paper is process-constrained, so conventional 3-pass knurled structure products are 2-pass knurled products. The predominance is not clear.

CN201510439764.5 is a method for producing multi-layer embossed toilet roll paper, which unwinds raw paper waiting for embossing, unwinds raw paper, and combines one layer or one or more layers of surface layer raw paper into fine embossed roller pairs. Fine embossing is obtained by guiding and pressing fine embossing, and the fine embossing of the surface layer is combined, and the obtained fine embossing paper and one layer of core layer raw material paper are combined and guided to a coarse embossing roller pair to obtain coarse embossing. The rough embossing of the surface layer and the core layer, which obtains the coarse embossed paper, and the obtained coarse embossed paper are guided to a roller pair consisting of a water rubber roller coated with a binder and a coarse embossed steel roller, and the obtained coarse embossed paper is obtained. A preparation coarse embossed paper is obtained by applying a binder to the concave surface on the core layer side of the embossed paper. The bottom layer fine embossing, the obtained preparation coarse embossed paper, and the obtained bottom layer fine embossed paper are rewound to obtain the bottom layer fine embossed paper, and the coarse embossed concave surface of the prepared coarse embossed paper and the concave surface of the bottom layer fine embossed paper. Includes rewinding and packaging to obtain a multi-layer embossed toilet roll paper in which both the surface layer convex surface and the bottom layer convex surface are relatively provided, which are adhered and connected in the rewinding process and packaged.

The above plan realizes 3-pass embossing of a surface layer, a core layer, and a bottom layer, but due to process restrictions, the superiority of the conventional 3-pass knurled structure product over the 2-pass knurled product is not clear. Since the surface layer has been embossed twice, the fiber bond points in the toilet paper are largely tensile-broken and destroyed, so that the strength of the surface layer toilet paper is low, and when it gets wet, it easily rots and the user experience is deteriorated. It will be. The structure formed after joining the surface layer and the core layer embossed twice cannot greatly increase the thickness structure of the product, and the change in absorbency and texture is not clear.

The first embossed layer high protrusion 21 in one embossed layer penetrates the second embossed layer 20c and the third embossed layer 30, and finally three different embossed layers are attached and locked together to form one strong solid. Form the structure.

As described above, the present invention provides a tissue and a method for producing the same, and by limitation to a three-layer embossed pattern, the first embossed layer high protrusion and the second embossed layer protrusion or the second embossed layer protrusion plane. Are extruded from each other and fitted together, and a binder is applied, leaving an embossed mark of the first embossed layer high protrusion on the surface of the second embossed layer in the composite process of the first embossed layer and the second embossed layer. In addition, a binder is applied to the trace, and after being extruded by a roller with a constant force, it is attached to the third embossing layer, and the density of the low projections of the first embossing layer is the density of the projections of the second embossing layer. Higher than the density, some of the first embossed layer low protrusions are supported by the second embossed layer protrusions, and some of the first embossed layer low protrusions are supported by the second embossed layer interprojection plane. The thickness of the product is maximized, the product thickness is increased by 52% compared to the traditional three-layer embossing process structure, and the third embossing layer is mainly a constant density embossing dot, embossing. Since the density of points is generally similar to that of the first embossed layer, a similar touch feel is obtained, and the high protrusions of the first embossed layer in the first embossed layer form the second embossed layer and the third embossed layer. It penetrates and finally three different embossed layers are pasted and locked together to form one strong three-dimensional structure, which greatly enhances the physical performance of the tissue product in terms of thickness, tactile sensation, absorbency, etc. Up to.

The above description is only a preferred embodiment of the present invention, and it should be pointed out that those skilled in the art may make slight improvements and modifications without departing from the principle of the present invention. Modifications should also be considered as the scope of protection of the present invention.
