Punched picture paper and its making method

Abstract

The present application belongs to the technical field of handmade paper, and particularly relates to a hole-stitched painting rice paper and a manufacturing method thereof. The manufacturing process is different from that of common rice paper, and a layer of cloth is laid between the paper layers. Firstly, the cloth is beneficial to the formation of the wet paper layer. Secondly, the wet paper stack after fishing only needs to be pressed to remove most of the water, and the processes of baking and pouring are not needed. Thirdly, the paper is easier to operate in the paper uncovering process of the paper drying process, and the paper layer is not easy to be damaged. In the paper drying process, paste is brushed on the edge of the wet paper layer, and then the edges are pasted on the baking wall for baking. The inner paper surface is separated from the baking wall, so that the uneven drying of the inner and outer sides of the paper can be avoided.

Description

Technical Field

[0001] This invention belongs to the field of handmade Xuan paper technology, specifically relating to a perforated Xuan paper and its production method. Background Technology

[0002] Perforated painting is a technique that involves using a needle to poke holes in Xuan paper at different angles. The resulting holes create visual variations in light and shadow under different lighting conditions. Five different needle techniques—up, down, left, right, and vertical—are used to create these holes. Therefore, perforated painting requires specific thickness and stiffness of the Xuan paper: if the paper is too thin, the angles of the holes cannot be shown; if the paper is too stiff, the process of making the holes becomes difficult; and if the paper is too soft, it easily deforms, causing changes in the angles of the holes and affecting the final artwork's aesthetic appeal. Other requirements include the smoothness, toughness, tear resistance, elongation, and elasticity of the Xuan paper.

[0003] Most existing Xuan paper products are developed and produced for traditional calligraphy and painting, and there are no products suitable for making perforated paintings. Therefore, in order to meet the needs of perforated paintings, it is necessary to research and produce special Xuan paper suitable for the creation of perforated paintings. Summary of the Invention

[0004] The purpose of this invention is to provide a perforated Xuan paper that can meet the creative needs of perforated paintings.

[0005] To achieve the above objectives, the technical solution adopted by this invention is as follows: a perforated Xuan paper, characterized in that: the pulp concentration is 1.10-1.20%, the pulp consistency is 65-72°SR; the finished paper specifications are: weight 350-400g / m³. 2 Whiteness 75-78%.

[0006] Another object of the present invention is to provide a method for producing perforated Xuan paper, comprising the following steps:

[0007] (1) Paper scooping process: A cloth layer is laid on the paper stacking platform, and the scooped wet paper layer is laid on the cloth layer. The cloth layer and wet paper layer are laid on the cloth layer and continued until the paper scooping is completed. Then, a cloth layer is laid on the top wet paper layer to obtain a wet paper stack. The area of ​​the cloth layer is larger than the area of ​​the wet paper layer and the wet paper layer is laid within the cloth surface area. The obtained wet paper stack is pressed and air-dried to obtain a paper stack to be pulled.

[0008] (2) Paper drying process: Remove the cloth layer from the stack of paper to be pulled out, pull out the wet paper layer and place it on a clean flat surface. After applying paste to the four edges of the wet paper layer, stick the paper side with paste on it to the heated baking wall, dry and collect the paper.

[0009] Unlike the production process of ordinary Xuan paper, the perforated Xuan paper is thick and difficult to shape. Therefore, a layer of cloth (ordinary plain white cotton cloth is sufficient) is laid between the paper layers. This serves several purposes: first, it facilitates the shaping of the wet paper layers; second, after the wet paper is soaked, most of the water only needs to be squeezed out, eliminating the need for drying and pouring (that is, drying the paper stack and storing it, then soaking it in water again before peeling it off); and third, it makes the peeling process during the drying process easier and less likely to damage the paper layers.

[0010] The drying process for this type of paper is not the conventional method of applying a layer of wet paper entirely to the drying wall. Instead, paste is applied to the edges of the wet paper layer, and then the edges are adhered to the drying wall for drying. This is because this type of perforated Xuan paper is very thick and heavy. Ordinary drying methods cannot keep the paper on the drying wall for a long time without it falling off. Furthermore, the thick layer of paper can cause the inner surface to dry while the outer surface remains highly moist, leading to warping, bubbling, and rendering the paper unusable. By adhering the edges to the drying wall, the inner surface of the paper is separated from the wall, thus preventing uneven drying of the paper.

[0011] Paper cutting involves not trimming the edges of the paper after it has been collected. To prevent the paper from easily absorbing moisture from the air and deforming due to its thickness, air conditioning is used to maintain a constant temperature and humidity. Detailed Implementation

[0012] The technical solution of this method will be further detailed below.

[0013] A type of perforated Xuan paper, characterized by: a pulp concentration of 1.10-1.20% and a pulp consistency of 65-72°SR; and finished paper specifications of 350-400 g / m². 2 Whiteness 75-78%. Preferably, the pulp concentration is 1.15% and the pulp consistency is 69°SR; finished paper specifications: weight 380g / m². 2 The whiteness is 76.8%. When making paper, the amount of chemicals added is generally controlled to about 20 sheets per slot.

[0014] A method for producing perforated Xuan paper includes the following steps:

[0015] (1) Paper scooping process: A cloth layer is laid on the paper stacking platform, and the scooped wet paper layer is laid on the cloth layer. The cloth layer and wet paper layer are laid on the cloth layer and continued until the paper scooping is completed. Then, a cloth layer is laid on the top wet paper layer to obtain a wet paper stack. The area of ​​the cloth layer is larger than the area of ​​the wet paper layer and the wet paper layer is laid within the cloth surface area. The obtained wet paper stack is pressed and air-dried to obtain a paper stack to be pulled.

[0016] (2) Paper drying process: Remove the cloth layer from the stack of paper to be pulled out, pull out the wet paper layer and place it on a clean flat surface. After applying paste to the four edges of the wet paper layer, stick the paper side with paste on it to the heated baking wall, dry and collect the paper.

[0017] Specifically, the cloth used in this embodiment is a moistened plain-weave white cotton cloth. When scooping the paper, first place a layer of cloth on the paper stacking table. After scooping the paper, place it flat on the cloth, then lay another layer of fine white cloth on top of the paper. Repeat this process of scooping and laying cloth, placing one sheet of paper and then another layer of cloth. After the last sheet of wet paper is placed, lay another layer of cloth on top. After the paper is scooped, it is pressed but not coiled, and allowed to dry naturally. Generally, if the paper is scooped in the morning, it can be dried in the afternoon, requiring only 2-3 hours in between.

[0018] In the paper drying process of step (2), when applying paste to the edge of the wet paper, a gap is left on one side of the edge. After the wet paper layer is pasted onto the baking wall, air is blown from the gap between the wet paper layer and the baking wall to make the wet paper layer slightly bulge. In specific operation, the paste can be applied intermittently on one side of the wet paper, leaving a gap where no paste is applied. Alternatively, after applying paste to all four edges of the wet paper, a small strip of paper can be pasted onto the paste to cover the paste and form a gap. After the side of the wet paper layer with paste is pasted onto the baking wall, air is blown from the gap into the paper surface to make the wet paper layer slightly bulge. In other words, after blowing air, the four edges of the wet paper layer (except for the gap) are pasted onto the baking wall, and the middle paper surface is separated from the baking wall by an air layer. In this way, the moisture of the inner paper layer enters the middle air layer and is released outward from the gap, making the paper surface drying process more uniform and preventing curling. The gap also makes it easier to collect the paper.

[0019] Before drying the paper, heat the oven to 30-35℃, then stop heating and maintain this temperature. Dry slowly at a low temperature for 4.5-5.5 hours, usually around 5 hours. After the wet paper layer is dried, polish it with a jade stone to smooth the surface and increase its gloss. You can polish it directly on the oven wall before collecting the paper. The edges of the paper should be attached to the oven wall to maintain stability and facilitate polishing. When collecting the paper, use a smooth, thin bamboo strip to scrape the edges of the paper layer off the oven wall to obtain the dried Xuan paper. You can start collecting the paper from the gaps. Insert the thin bamboo strip between the paper layer and the oven wall and scrape the paper layer from the inside to the outside edge.

[0020] Once the paper is received, it becomes rough-edged paper, which is the finished product and can be sold without trimming the rough edges. Finished paper should be stored at a temperature of 25℃ to prevent it from deforming due to absorbing moisture from the air because it is too thick.

[0021] In Xuan paper painting, holes are punched with a needle. In addition to meeting the requirements of paper thickness and strength, the surface flatness of Xuan paper also meets the requirements of painting. It can reflect the three-dimensionality and layering of landscapes, figures and objects, and is very popular among painters.
