Embodiment 1

[0022] In this embodiment, the upper surface paper 11 and the lower surface paper 13 of the surface paper 10 are both made with a general fiber ratio, specifically 20% long-fiber virgin wood pulp + 80% short-fiber virgin wood pulp.

[0023] In this embodiment, the core paper 20 has a single-layer structure, and the formula adopted is 15% wollastonite fiber + 15% long-fiber virgin wood pulp + 70% short-fiber virgin wood pulp.

Embodiment 2

[0025] In this embodiment, the upper surface paper 11 and the lower surface paper 13 of the surface paper 10 are both made with a general fiber ratio, specifically 30% long-fiber virgin wood pulp + 70% short-fiber virgin wood pulp.

[0026] In this embodiment, the core paper 20 has a single-layer structure, and the formula adopted is 5% polypropylene fiber + 15% long-fiber virgin wood pulp + 80% short-fiber virgin wood pulp.

Embodiment 3

[0028] In this embodiment, the upper surface paper 11 and the lower surface paper 13 of the surface paper 10 are made with a general fiber ratio, specifically 40% short-fiber virgin wood pulp + 60% bamboo pulp.

[0029] In this embodiment, the core paper 20 has a single-layer structure, and the formula adopted is 20% sepiolite fiber + 20% long-fiber virgin wood pulp + 60% short-fiber virgin wood pulp.

[0030] During the use of the multi-layer household paper 100 prepared in Example 1, Example 2 and Example 3, the surface paper 10 is in direct contact with the skin of the user, so the surface paper 10 is required to be softer. However, the core paper 20 does not need a higher hand feeling requirement. Combine the surface paper 10 and the core paper 20 to give full play to the functions of the surface paper 10 and the core paper 20, which not only meets the requirements for the feel of use, but also meets the requirements for strength during use, and can effectively reduce the ...

Abstract

Paper for daily use comprises a piece of surface paper and a piece of core paper, wherein the surface paper comprises a piece of upper paper and a piece of a lower paper; the core paper is arranged between the upper paper and the lower paper; the upper paper and the lower paper are composite fiber layers formed by native wood pulp fiber layers, native non-wood pulp fiber layers or native wood pulp fiber and non-native wood pulp fiber; the core paper adopts a single layer or multilayer structure; and at least one layer of the core paper is a composite fiber layer contains non-plant pulp fiber and plant pulp fiber. The paper for daily use can not only meet use requirements, but also can effectively reduce the production cost.

Description

technical field [0001] The invention relates to a household paper. Background technique [0002] Currently commercially available household paper is usually single-layer or multi-layer, and most of the multi-layer household paper is made of 2-4 layers of paper by rewinding or lamination, and the material and physical properties of each layer of paper are unanimous. The use characteristics of high-end household paper mainly require high strength and good hand feeling. In order to ensure these two characteristics, high-end household paper is mostly made of virgin wood pulp fibers, but all of them are made of virgin wood pulp, making the household paper The overall input cost is higher. Contents of the invention [0003] In view of this, a household paper that can not only meet the use requirements but also reduce the cost is provided. [0004] A household paper, which comprises a surface paper and a core paper, the surface paper includes an upper surface paper and a lower...
