Description
Technical Field
The invention relates to a preparation method of a double-layer folding type paper extraction and the double-layer folding type paper extraction obtained by the preparation method.
Background
The tissue is commonly used in daily life of people, and the quality of the tissue directly influences the paper using experience of people. At present, in the production process of tissue paper, base paper is usually unreeled and then folded and cut by a folding device to form a mutually folded laminated body, and then the laminated body is cut and packaged according to needs.
However, conventional paper tissue has a drawback that it is not sufficient in overall tenacity and strength and is easily torn or broken. The base paper used for making paper extracts is generally made by laminating a plurality of sheets, usually two or three. In the production of the multi-layer paper constituting the base paper, the fibers in the paper generally have a certain orientation. In particular, in both papermaking and wire-laying processes, the pulp flows in a certain direction, so that fibers, particularly long fibers, in the pulp tend to be arranged along the direction of the pulp flow. Therefore, the fibers in the prepared paper also show certain directionality. After paper with fibers having certain directionality in the paper is laminated into base paper, the tissue paper directly prepared by the processes of unreeling, folding, cutting and the like also has certain directionality. Because the fibers in the paper and the base paper have certain directionality, the prepared paper is high in toughness along the fiber direction in the paper, and the toughness strength in the direction perpendicular to the fiber direction in the paper is obviously insufficient, so that the paper is easy to tear or break in the direction.
At present, it is common to directly reinforce the strength of the original paper, for example, to increase the thickness of the paper, thereby reinforcing the strength of the paper in the above two directions. But this method causes a significant increase in production costs. Therefore, the invention aims to provide a simple method for manufacturing double-layer tissue, which can obviously improve the comprehensive toughness strength.
Disclosure of Invention
In order to solve the defect of insufficient comprehensive toughness strength of the paper extraction in the prior art, the invention provides a preparation method of double-layer folding paper extraction, which increases the comprehensive toughness strength of the paper extraction on the premise of not increasing the thickness of paper forming base paper. In the double-layer folding type paper extraction, the paper extraction base paper is formed by laminating two layers of paper, fibers in the two layers of paper have certain directionality, but in the laminating process, the fiber directions of the two layers of paper are set to be in a non-parallel state, so that the comprehensive toughness strength of the laminated paper extraction base paper can be obviously improved.
Therefore, the invention provides a preparation method of double-layer folding type paper extraction, wherein the double-layer folding type paper extraction is characterized in that the paper extraction base paper of the double-layer folding type paper extraction is unreeled, then is folded and cut by a folding device to form a mutually folded laminated body, and then is cut and packaged according to the required paper extraction size, and the preparation method comprises the following steps: the base paper for paper extraction is of a double-layer structure and is formed by laminating two layers of paper, fibers in each layer of paper show certain directionality, and the base paper for paper extraction is obtained by laminating the fiber directions of the two layers of paper in a non-parallel state.
Further, the non-parallel state means that the angle of the fiber directions of the two layers of paper is 30 to 90 degrees, specifically 30, 45, 60, 75, 90 degrees, and preferably 90 degrees.
Further, the laminated base paper for paper extraction is imprinted to increase the lamination stability of the paper, wherein the imprinted pattern is one or more of a circle, a rectangle, a triangle and a wavy line.
Wherein, the in-process of impressing the paper extraction body paper, the equidistant impression of length direction along the paper extraction body paper, this interval equals the length of paper extraction for the pattern of impressing can be used as the sign of paper extraction on length direction, so that subsequent cutting.
The preparation method of the paper for forming the paper extraction base paper in a laminated mode comprises the following steps: selecting required fiber raw materials, pulping, deslagging, screening, papermaking, screening, pressing, drying and other processes to prepare paper, directly paving the prepared 1 st paper, and then, rotating the prepared 2 nd paper by 90 degrees and laminating the paper on the 1 st paper to obtain the raw paper for paper extraction. And by parity of reasoning, directly tiling the manufactured Nth paper, then rotating the manufactured (N + 1) th paper by 90 degrees and laminating the paper on the Nth paper to obtain the raw paper for paper extraction, wherein N is a positive odd number.
Wherein, the fiber raw material is selected from one or the combination of bamboo fiber and cotton fiber.
It is known that a paper sheet is excellent in tenacity in the fiber length direction thereof, but is significantly insufficient in tenacity perpendicular to the fiber length direction thereof, and fibers arranged in parallel are easily torn. Therefore, in the invention, by improving the preparation process of the base paper for paper extraction, the fiber directions of two pieces of paper which are laminated to form the base paper for paper extraction are laminated in a non-parallel state, particularly in a vertical state, so that the comprehensive toughness strength of the base paper for paper extraction in each direction is obviously improved, and the defect of insufficient comprehensive toughness strength of paper extraction in the prior art is overcome.
In addition, the simple range upon range of stability of paper is not enough for the easy layering of paper stock through impressing it, can improve this defect, moreover, through the length direction that uses the paper stock along paper stock carry out equidistant impression as the interval with the length of paper stock, can also regard as the sign of paper in length direction with the pattern of impressing, the subsequent cutting of being convenient for, kill two birds with one stone.
