Description

Technical Field

[0001] This invention relates to the field of printed fabric technology, specifically to a fish skeleton-shaped printed coated fabric and its preparation method. Background Art

[0002] Currently, most printed coatings on shoe materials are created using screen printing to form a smooth surface, resulting in a weak visual impact. To achieve more surface effects, existing technologies typically employ embossing printing. For example, Chinese invention patent CN101284443A uses an embossing plate printing machine for three-dimensional printing, which not only enhances the tactile feel of the printed coating surface but also increases visual impact. However, embossing often results in less refined patterns, and the high temperatures involved in embossing can easily damage the coating's performance, while also consuming a lot of energy and being less environmentally friendly. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a fish skeleton-shaped printed coated fabric and its preparation method that does not involve high temperature.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows: a method for preparing a fish skeleton-shaped printed coating fabric, comprising the following steps: applying a printing coating paste to the bottom layer, then raising the plate at a speed of 0.01~0.2m / s, and obtaining a fish skeleton-shaped printed coating after drying; By weight, the printing coating paste comprises the following raw materials: 70-80 parts of waterborne polyurethane, 2.0-4.0 parts of fine fiber, 1.0-5.0 parts of slow-drying agent, 1.0-3.0 parts of cellulose ether, and 3-5 parts of crosslinking agent.

[0005] Another technical solution adopted in this invention is: a fish skeleton-shaped printed coated fabric, which is prepared by the above-mentioned fish skeleton-shaped printed coated fabric preparation method.

[0006] The beneficial effects of the present invention are as follows: The preparation method of the present invention slowly raises the printing plate on a special printing coating, changing the movement direction of the printing coating paste, thereby obtaining a delicate fish skeleton-shaped three-dimensional printing, which increases the surface feel and visual impact of the printing coating. The preparation method of the present invention does not involve high temperature, is environmentally friendly and low-consumption. Attached Figure Description

Protective layer; 2. Luminous printed coating; 21. Main raised structure; 22. Secondary raised structure; 3. Base layer. Detailed Implementation

[0008] To explain in detail the technical content, objectives, and effects of the present invention, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0009] A method for preparing a fish skeleton-shaped printed coated fabric includes the following steps: applying a printing coating paste to a base layer, then raising the printing plate at a speed of 0.01~0.2m / s, and obtaining a fish skeleton-shaped printed coating after drying. By weight, the printing coating paste includes the following raw materials: 70-80 parts of waterborne polyurethane, 2.0-4.0 parts of fine fiber, 1.0-5.0 parts of slow-drying agent, 1.0-3.0 parts of cellulose ether, and 3-5 parts of crosslinking agent.

[0010] As can be seen from the above description, the beneficial effects of the present invention are as follows: the preparation method of the present invention slowly raises the plate on a special printing coating. The raising speed affects the movement and breakage of the paste. When raising the plate, the direction of the object's movement is instantly changed by the traction force. The surface of the printing coating presents a relatively uniform multi-ridged (similar to a fishbone) effect, which not only increases the tactile feel of the surface but also increases the visual impact. In addition, the preparation method does not involve high temperature, and is environmentally friendly and low-consumption.

[0011] The fine fibers promote the breakage of the paste during the slow screen-forming process, making the fishbone-like shape more pronounced and increasing the uprightness of the fishbone pattern after application. The slow-drying agent prevents screen clogging during batch printing. Cellulose ethers act as a thickener, making the paste easier to apply and also increasing the uprightness of the fishbone pattern.

[0012] Furthermore, the bottom layer is a raw fabric, or a raw fabric with a foamed layer printed on it, or a raw fabric with an ink layer printed on it.

[0013] Furthermore, the length of the fine fibers is 50~300μm.

[0014] Furthermore, the squeegee should be tilted at 15-40° when applying the printing coating paste.

[0015] As can be seen from the above description, when the scraper is tilted at 15~40°, the material can be fed more, which can improve the effect of multiple edges and corners when the plate is made later.

[0016] Furthermore, the thickness of the coating paste for scraping printing is 0.1~0.3mm.

[0017] As can be seen from the above description, the thickness of the coating paste for scraping printing in this invention is slightly higher than that of conventional single printing, which improves the effect of multiple edges and corners when the plate is subsequently made.

[0018] Furthermore, the scraping speed when applying the printing coating paste is 0.05~0.3m / s.

[0019] As can be seen from the above description, after light scraping, the pattern area is covered with printing coating paste to form a uniform multi-ridge shape.

[0020] Furthermore, the viscosity of the printing coating paste is 120,000~180,000 cps.

[0021] As can be seen from the above description, the printing coating paste has a high viscosity and a strong bond with the screen. When the screen is lifted, the movement direction of the printing coating paste is instantly changed by the traction force of the screen.

[0022] Furthermore, by weight, the printing coating paste also includes 0.6 to 1.0 parts of dispersant, 0.3 to 0.6 parts of defoamer, and 1.0 to 3.0 parts of silica.

[0023] Furthermore, by weight, the printing coating paste also includes 5-10 parts of transparent powder and 5-10 parts of luminescent powder.

[0024] Furthermore, by weight, the printing coating paste includes the following raw materials: 70-80 parts of waterborne polyurethane, 0.6-1.0 parts of dispersant, 0.3-0.6 parts of defoamer, 1.0-3.0 parts of silica, 2.0-4.0 parts of fine fiber, 5-10 parts of transparent powder, 5-10 parts of luminescent powder, 1.0-5.0 parts of slow-drying agent, 1.0-3.0 parts of cellulose ether, and 3-5 parts of crosslinking agent.

[0025] As can be seen from the above description, the printed coating of the present invention has a "fishbone" structure distribution, forming a raised effect of different heights, which leads to a larger surface area of ​​the printed coating, increased energy absorption by the luminescent powder, and a longer-lasting luminescent effect in the dark.

[0026] The amount of luminescent powder should not be too high, otherwise it will reduce the coating performance.

[0027] Furthermore, the drying conditions are as follows: after natural drying for 8 to 16 hours, dry at 50 to 60°C for 24 to 48 hours, and then cool to obtain a fish skeleton-shaped printed coating.

[0028] As can be seen from the above description, the protective layer is relatively thick. If it is dried directly at 50~60℃, it is easy to cause bubbles and poor surface finish of the coating.

[0029] Furthermore, it also includes the step of applying a 1.0~3.0mm protective layer onto the undried fish skeleton-shaped printed coating.

[0030] As can be seen from the above description, the protective layer can increase the lifespan of the printed coating, improve its wear resistance and washability, and also add a certain amount of translucent color to provide better color effects.

[0031] Applying a protective layer to the undried fishbone-shaped printed coating can improve the adhesion between the two.

[0032] Another technical solution adopted in this invention is: a fish skeleton-shaped printed coated fabric, which is prepared by the above-mentioned fish skeleton-shaped printed coated fabric preparation method.

[0033] Please refer to Figure 2 and 3 Furthermore, it includes a protective layer, a fishbone-shaped printed coating, and a base layer arranged from top to bottom; The fish skeleton-shaped printed coating includes a main raised structure and a secondary raised structure. One end of the secondary raised structure is connected to the main raised structure to form a fish skeleton shape. The cross-section of the main raised structure is a triangle with irregular edges.

[0034] As can be seen from the above description, the distribution of the main protrusions on the flower position is similar to the "vertebrae" of a fish skeleton, and the distribution of the secondary protrusions on the flower position is similar to the "ribs" of a fish skeleton.

[0035] Conventional flat printed coatings are prone to cracking when bent due to the large force exerted on their surface. The fish skeleton-shaped printed coating of this invention has a natural texture that can decompose the bending force. During flexural testing, the pyramidal structure reduces the surface stress, making it less prone to cracking. Even if cracking occurs, it is not easily detected due to the small visual differences in the textured structure.

[0036] Furthermore, the width of the cross-section of the main protrusion structure increases from top to bottom.

[0037] As described above, the width of the cross-section of the main raised structure increases from top to bottom, which enhances the sense of layering and light and shadow effects, improving the tactile experience; it also disperses pressure, improving the stability of the 3D printing. This structure can more effectively reflect and scatter light, making the luminous effect more concentrated and bright.

[0038] Furthermore, the number of main protrusion structures is one or at least two connected together.

[0039] Furthermore, the cross-section of the secondary protrusion structure is a triangle with irregular edges.

[0040] As can be seen from the above description, the cross-sections of both the main protrusion structure and the secondary protrusion structure are irregularly shaped triangles, which can effectively increase the surface area of ​​the printed coating.

[0041] Furthermore, the height of the secondary protrusion gradually decreases from the end closest to the main protrusion to the end furthest from the main protrusion.

[0042] Furthermore, the secondary protrusions are distributed on one side or around the main protrusion.

[0043] Furthermore, the height of the secondary protrusion structure is lower than the height of the primary protrusion structure.

[0044] Furthermore, there are at least two secondary protrusions, which are either separated from each other or partially connected.

[0045] Furthermore, the protective layer completely covers the fish skeleton-shaped printed coating.

[0046] Furthermore, the protective layer is transparent or semi-transparent.

[0047] Furthermore, the fish skeleton-shaped printed coating is at least one layer.

[0048] As can be seen from the above description, there can be zero, one or more intermediate printing coatings between the bottom layer and the herringbone-shaped printing layer, and the height can be changed according to the process design.
