[0002] In recent years, with the progress of society and the improvement of people's living standards, the demand for footwear products has been continuously increasing, and consumers have put forward higher requirements for the appearance and functions of shoes. Among numerous shoe material decoration technologies, the printing coating technology has received extensive attention and application because it can achieve high-quality pattern effects and good durability. Therefore, there are also higher and higher requirements for the completion efficiency of the printed coating and the quality of the completed products. The production efficiency and product quality are closely related to the process of printing patterns.

[0003] However, the existing process for printed pattern products of shoe materials is mainly to first print a layer of pattern on a plastic film to form a plastic film layer with a pattern, and then this plastic film layer is bonded to the surface protection layer through a gluing or sticking process. The plastic film and the protection layer of the product made by this process are prone to cracking, and the pattern layer is prone to delamination, resulting in poor product quality and unable to meet the market demand. Summary of the Invention

[0004] The purpose of the present invention is to solve the above technical problems and provide a preparation method and application of a printed product of shoe materials. The product produced by this preparation method is not easy to crack and the coating is not easy to delaminate, thereby improving the product quality and quality.

[0005] To achieve the above purpose, in the first aspect, the inventor of the present invention provides a preparation method of a printed product of shoe materials, including the following steps: Step 1: First, use a 3D printing machine to evenly coat a layer of PU glue on the surface of the fabric, and dry the surface of the fabric. The drying temperature is 80-100 degrees, and the drying time is 3-5 seconds, so as to form a glue printing layer on the surface of the fabric body and obtain a glue-printed object. Step 2: Coat a layer of white PU ink on the surface of the glue-printed object obtained in Step 1 to form an ink area, then print a pattern on the surface of the ink area, and dry the pattern on the glue-printed object. The drying temperature is 80-100 degrees, and the drying time is 3-5 seconds, so that a pattern area is formed on the ink area. Step 3: Continue to coat a layer of white PU ink on the surface of the glue-printed object obtained in Step 2, and continue to dry. The drying temperature is 80-100 degrees, and the drying time is 3-5 seconds, to obtain a patterned fabric. Step 4: Cut the patterned fabric obtained in Step 3 according to the required specifications, put the cut fabric into a mold, and inject a transparent material into the mold, so that a protective layer with an integral structure is formed on the surface of the patterned fabric layer. After the mold is cooled, take out the product in the mold, and the printed product of shoe materials is obtained.

[0006] Preferably, in step four of the present invention, the mold injects transparent material through a plastic mold machine.

[0007] Preferably, the heating temperature of the plastic mold machine of the present invention is 160 - 175 °C.

[0008] Preferably, the mold cooling of the present invention adopts natural cooling for 180 seconds.

[0009] Preferably, the transparent material in step four of the present invention is one of PVC or PU.

[0010] Preferably, an anti-slip structure is formed on the side of the protective layer facing away from the fabric layer.

[0012] In a second aspect, the inventor provides a sole, and the shoe material printed product on the sole is made by using the preparation method described in the first aspect.

[0013] In a third aspect, the inventor provides a shoe, and the shoe is made of the sole described in the second aspect.

[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention coats PU glue and PU ink between the pattern layer and the fabric body, improving the peel strength between the PU ink and the fabric body, making the pattern layer on the fabric surface not easy to delaminate and degenerate.

[0015] 2. The present invention coats PU ink between the protective layer and the pattern layer, improving the peel strength between the protective layer, the pattern layer and the fabric body, making it not easy to crack between the protective layer and the fabric body, thereby improving the quality of the product.
