Problems solved by technology

Among them, many small steps are included in the suede coloring step, and various chemical treatment agents are used in these small steps. Different factory conditions have different pollution control capabilities. In order to effectively control pollution, a huge cost must be invested, which also pushes up the cost of the product, and the resulting yield is low.
In the surface treatment process, some of the surface of the microfiber suede is coated with a color layer, but the pollution of the coating material is also very large during the coating process, and some of the surface of the microfiber suede Spraying will also cause the resulting leather products to be hard and feel bad due to the infiltration of the spraying material

Embodiment 1

[0025] Example 1: as figure 1 As shown, the surface treatment method of the transfer film directly attached to the microfiber suede leather includes the following process steps:

[0026] 1) Prepare the material transfer film roll, and at the same time prepare the microfiber suede roll and the hot-pressing laminating machine;

[0027] The transfer film in the transfer film roll material includes a carrier layer 1 , a release layer 2 , and an adhesive layer 3 , the release layer is coated on the carrier layer 1 , and the adhesive layer is coated on the release layer. The carrier layer is a PET film layer. The adhesive layer is a TPU resin layer.

[0028] 2) Pulling the transfer film and the microfiber suede into alignment on the opposite rollers of the hot-pressing laminating machine, heating and rolling, wherein the carrier layer of the transfer film contacts the hot roller, and the adhesive layer of the transfer film contacts the microfiber suede leather 4;

Embodiment 2

[0033] Example 2: as figure 2 As shown, the surface treatment method of the transfer film directly attached to the microfiber suede leather includes the following process steps:

[0034] 1) Prepare the material transfer film roll, and at the same time prepare the microfiber suede roll and the hot-pressing laminating machine;

[0035] The transfer film in the transfer film roll material includes a carrier layer 1, a release layer 2, an intermediate layer 5, and an adhesive layer 3. The release layer is coated on the carrier layer, the intermediate layer is coated on the release layer, and the adhesive layer is coated on the release layer. The layer is coated on the intermediate layer. The carrier layer is a PET film layer. The adhesive layer is a TPU resin layer. The intermediate layer is a color layer, which can be of various colors. The intermediate layer can also be a pattern layer.

Abstract

The invention discloses a surface treatment method by directly sticking a transfer film to ultrafine fiber napped leather, which is characterized in that the method comprises the following processing steps: 1) preparing transfer film coiled material, ultrafine fiber napped leather coiled material and a hot-pressing laminating machine; 2) pulling the transfer film and ultrafine fiber napped leather aligned into a double-roll of the hot-pressing laminating machine, and performing hot pressing and rolling, wherein a carrier layer of the transfer film contacts a hot roller and an adhesive layer of the transfer film contacts the ultrafine fiber napped leather; 3) continuously pulling the ultrafine fiber napped leather and the transfer film out of the double-roll, thereby sticking the transfer film to the ultrafine fiber napped leather at this time; and 4) peeling the carrier layer to obtain the finished product. The product obtained by the treatment method of the invention has soft and smooth handfeel, and can be kept on subsequent processes such as lacquering, silk-screen printing, transfer printing, embossing and the like. The surface treatment method of the invention has a simple process and no environmental issues of solvent consumption and recovery, saves a great amount of equipment investment and energy consumption, and improves the site working conditions. Therefore, the surface treatment method of the invention is a desirable substitute of the prior art.

Description

technical field [0001] The invention relates to a surface treatment method in which a transfer film is directly attached to a superfine fiber suede leather, and the surface treatment method is used for the surface treatment of the superfine fiber suede. Background technique [0002] Microfiber suede is a highly imitation leather material that has a wide range of applications. In the prior art, the traditional transfer film is directly attached to the surface of the superfine fiber suede leather, and some process steps are as follows: 1. suede cleaning. Second, the suede color. Among them, the suede coloring step also includes many small steps. In these small steps, a variety of chemical treatment agents are used. These chemical treatment agents have strong odor, are flammable and explosive, and cause great pollution to the environment. Different factory conditions have different ability to control pollution. In order to effectively control pollution, a huge cost must be in...
