Problems solved by technology

However, the strength and feel of the base paper are contrary to each other, and the two are often not compatible. If the paper is soft, the strength of the paper is often poor, resulting in easy paper breaks during the rewinding process and poor stiffness, which is not conducive to printing. Folding and printing of paper and ink pattern printing; if the base paper with high strength is used for multiple layers, the hand feeling of the whole household paper will be poor

Embodiment 1

[0037] The household paper 100 of this embodiment is a printed napkin, which is formed by laminating three layers of paper. Napkin-like household paper generally needs to be folded and printed with ink patterns. The base paper on the surface is required to have better stiffness and higher strength, which is convenient for folding and printing.

[0038] The upper surface paper 11 and the lower surface paper 13 both use 30% long-fiber virgin wood pulp and 70% short-fiber virgin wood pulp to mix and add chemicals (the dry strength agent is polyacrylamide, and the wet strength agent is polyamide -epichlorohydrin) slurry papermaking, the strength of the upper surface paper 11 and the lower surface paper 13 is higher (transverse strength is 4.2 ± 0.2N m / g, longitudinal strength is 3.0 ± 0.2N m / g ), the stiffness is better, because the original wood pulp is used, and the strength is increased by adding chemicals, the damage to the paper is less, and the paper is also softer.

Embodiment 2

[0042] The household paper 100 of this embodiment is a roll-type toilet paper.

[0043] Both the upper surface paper 11 and the lower surface paper 13 are made by mixing 30% long-fiber virgin wood pulp and 70% short-fiber virgin wood pulp, and then processed by refining. Under proper refining conditions, the upper surface paper 11 And the lower surface paper 13 has higher strength (the transverse strength is 4.2±0.2N m / g, the longitudinal strength is 3.0±0.2N m / g), and the higher strength of the surface paper 10 ensures that the toilet paper roll is pulled out. Not easy to be pulled off.

[0044] The core layer paper 20 is made of a mixed slurry of 40% short-fiber virgin wood pulp and 60% straw pulp. The strength of the core paper 20 is relatively low (the transverse strength is 2.4±0.2 N·m / g, the longitudinal strength is 1.3±0.2 N·m / g), and the hand feeling is slightly worse than that of the surface paper 10 .

[0045] If the roll household paper is made of multi-layer base...

Abstract

The invention discloses a type of household paper, which comprises surface layer paper and core layer paper, wherein the surface layer paper comprises upper surface layer paper and lower surface layer paper; the core layer paper is arranged between the upper surface layer paper and the lower surface layer paper; the core layer paper has a single-layer or multi-layer structure; the total strength of the surface layer paper is higher than that of the core layer paper; the transverse strength of the surface layer paper is 3.0-6.0N.m / g; the longitudinal strength of the surface layer paper is 2.0-4.5N.m / g; the transverse strength of the core layer paper is 2.0-3.0N.m / g; and the longitudinal strength of the core layer paper is 1.2-1.8N.m / g. According to the household paper disclosed by the invention, the characteristics of the surface layer paper and the core layer paper are utilized reasonably, so that the household paper has certain strength and high softness, is prevented from being broken easily in a rewinding process, can meet the requirement of handfeel, is clean on the surface, is prevented from falling paper scraps, and is easy to mold by folding and print.

Description

technical field [0001] The invention relates to a household paper. Background technique [0002] Currently commercially available household paper is mainly multi-layered, and the material and physical properties of each layer of base paper are usually the same. However, the strength and feel of the base paper are contrary to each other, and the two are often not compatible. If the paper is soft, the strength of the paper is often poor, resulting in easy paper breaks during the rewinding process and poor stiffness, which is not conducive to printing. Paper folding and ink pattern printing; if the base paper with high strength is used for multiple layers, the hand feeling of the whole household paper will be poor. Contents of the invention [0003] In view of this, a household paper that can effectively solve the above problems 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 ...
