Embodiment 1

[0016] A method for preparing double-layer folded paper, in which, the double-layer folded paper is unrolled from the paper base paper, folded and cut by a folding device to form a stacked body that is folded with each other, and then processed according to the required paper size. Cutting and packaging, characterized in that: the base paper for pumping is a double-layer structure, which is formed by laminating two layers of paper, and the fibers in each layer of paper show a certain directionality. Lamination was performed in a parallel state to obtain base paper.

[0017] Further, the non-parallel state means that the angle between the fiber directions of the two layers of paper is 90°.

[0018] Emboss the stacked paper base paper, specifically along the length direction of the paper base paper, and emboss at equal intervals, the distance is equal to the length of the paper, so that the embossed pattern can be used as a mark in the length direction of the paper , for subseq...

Embodiment 2

[0021] A method for preparing double-layer folded paper, in which, the double-layer folded paper is unrolled from the paper base paper, folded and cut by a folding device to form a stacked body that is folded with each other, and then processed according to the required paper size. Cutting and packaging, characterized in that: the base paper for pumping is a double-layer structure, which is formed by laminating two layers of paper, and the fibers in each layer of paper show a certain directionality. Lamination was performed in a parallel state to obtain base paper.

[0022] Further, the non-parallel state means that the angle between the fiber directions of the two layers of paper is 60°.

[0023] Emboss the stacked paper base paper, specifically along the length direction of the paper base paper, and emboss at equal intervals, the distance is equal to the length of the paper, so that the embossed pattern can be used as a mark in the length direction of the paper , for subseq...

Embodiment 3

[0026] A method for preparing double-layer folded paper, in which, the double-layer folded paper is unrolled from the paper base paper, folded and cut by a folding device to form a stacked body that is folded with each other, and then processed according to the required paper size. Cutting and packaging, characterized in that: the base paper for pumping is a double-layer structure, which is formed by laminating two layers of paper, and the fibers in each layer of paper show a certain directionality. Lamination was performed in a parallel state to obtain base paper.

[0027] Further, the non-parallel state means that the angle between the fiber directions of the two layers of paper is 45°.

[0028] Emboss the stacked paper base paper, specifically along the length direction of the paper base paper, and emboss at equal intervals, the distance is equal to the length of the paper, so that the embossed pattern can be used as a mark in the length direction of the paper , for subseq...

Abstract

The invention relates to a manufacturing method of tissues, and provides a preparation method of double-layer folding tissues. The method comprises the following steps of unwinding tissue base paper,folding and cutting by a folding device to form a mutually-folded laminated body, and cutting and packaging the laminated body according to the required tissue size to obtain the double-layer foldingtissues. The method is characterized in that the tissue base paper is of a double-layer structure and is formed by laminating two layers of paper, fibers in each layer of paper have certain directionality, and the tissue base paper is obtained through laminating the fiber directions of the two layers of paper in a non-parallel state. Particularly, the paper is laminated in a 90-degree state to form the tissue base paper, so that the comprehensive toughness and strength of the tissue base paper in all directions are obviously improved, and the defect of insufficient comprehensive toughness andstrength of the tissues in the prior art is overcome.

Description

technical field [0001] The invention relates to a preparation method of a double-layer folding pumping paper and the double-layer folding pumping paper obtained therefrom. Background technique [0002] Paper is often used in people's daily life, and the quality of paper directly affects people's paper experience. At present, in the production process of pumping paper, the base paper is usually unrolled and then folded and cut by a folding device to form a folded laminate, which is then cut and packaged as required. [0003] However, in the existing pumping paper, there is a defect that the comprehensive toughness and strength are insufficient, and it is easy to be torn or pulled off. The base paper used to make paper is usually laminated with multiple layers of paper, usually two or three layers. In the manufacturing process of the multi-layer paper that constitutes the base paper, the fibers in the paper usually have a certain directionality. Especially in the two proces...
