Embodiment 1
[0034] like figure 1 It is a schematic structural diagram of the layer structure used for fabric inkjet hollow printing, which includes a substrate layer 1, a release layer 2, an ink-absorbing layer 3, a graphic layer 4, a white or colorless ink layer 5 and a thermal layer from bottom to top. The melt glue powder layer 6; the graphic hollow part 7 is located in the graphic layer 4.
[0035] The division of labor and technology of each layer in the figure is as follows:
[0036] Substrate layer 1: Substrate layer 1 is base paper or plastic film, which is used to carry various functional layers on the surface. Since the thermal transfer temperature is generally heated and pressurized at 130-180 °C (the preferred temperature is 150-170 °C) ), so the base paper or plastic film not only requires a certain strength, but also requires that it can withstand high temperature of 200 ° C for several minutes without deformation. Considering its technical performance requirements and econ...
Embodiment 2
[0044] Fabric inkjet hollow printing methods, including the following two methods:
[0045] The first preparation method: the substrate layer (1) is coated with a release layer (2) and an ink-absorbing layer (3) on a common coating machine, and prefabricated into an inkjet release paper or a release film (8); The ink release paper or release film (8) passes through a CMYK color inkjet printing unit (9) loaded with paint ink, and inkjet prints a graphic layer (4) on the surface of the inkjet release paper or release film (8); Then, through the CMYKW inkjet printing unit (10) loaded with color paint ink, the inkjet printing of the color paint ink is continued on the original image and text, so that the color of the image and text layer (4) is thickened; and then through the WL printing unit (11) loaded with colorless ink. , continue inkjet printing of colorless ink on the original image and text to form a colorless ink layer (5), and enter the dusting unit (12) when it is not dr...
Embodiment 3
[0050] The release layer includes the following raw materials in parts by weight: 9.7 parts of acrylic release agent and 0.3 parts of silicon dioxide powder. The above raw materials are mixed and stirred evenly, and coated on the surface of the PET film to form release layer 2. After testing, the release layer 2 The surface tension is 28 dynes.
[0051] Use oil-based paint ink to print graphics: on the surface of the release layer 2, use the color inkjet printing unit 9 loaded with oil-based resin ink to print the graphics layer 4, and then use a screen printer to print a white or colorless primer offline. Layer 5, when the primer layer 5 is not dry, sprinkle the hot-melt glue powder layer 6, so that the hot-melt powder is adhered to the ink marks of the graphics and text, and the excess hot-melt powder is absorbed and dried to complete the preparation of the inkjet printing hollow transfer film . When printing, place the hot melt adhesive powder layer 6 on the fabric that ne...
