Embodiment 1
[0034] Such as figure 1 It is a schematic diagram of the structure of the layer structure used for fabric inkjet hollow printing, from bottom to top, it includes the substrate layer 1, the release layer 2, the ink absorption layer 3, the graphic layer 4, the white or colorless ink layer 5 and the thermal Melt 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: The substrate layer 1 is a base paper or plastic film, which is used to carry various functional layers on the surface. Because the heat transfer temperature is generally 130-180℃, heating and pressing (preferably 150-170℃ ), so the base paper or plastic film not only requires a certain strength, but also needs to be able to withstand 200℃ high temperature for several minutes without deformation. Considering its technical performance requirements and economy, use GSM50-200 fiber paper o...
Embodiment 2
[0044] Fabric inkjet hollow printing methods include 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 an ordinary coating machine, and then pre-made into an inkjet release paper or release film (8); The ink release paper or release film (8) passes through the CMYK color inkjet printing unit (9) loaded with paint ink, and inkjet prints the graphic layer (4) on the surface of the ink release paper or release film (8); Then go through the CMYKW inkjet printing unit (10) loaded with color paint ink and continue to ink-jet print the color paint ink on the original graphic part to make the color of the graphic layer (4) thicker; then go through the WL printing unit (11) loaded with colorless ink , Continue to ink-jet print colorless ink on the original graphic part to form a colorless ink layer (5), and enter the dusting unit (12) without drying, and evenly sprinkle a layer of ...
Embodiment 3
[0050] The release layer includes the following raw materials by weight: 9.7 parts of acrylic release agent and 0.3 parts of silica powder. The above raw materials are mixed and stirred evenly, and coated on the surface of the PET film to form release layer 2. The release layer is tested. 2 The surface tension is 28 dynes.
[0051] Use oil-based paint ink to print graphics and text: On the surface of the release layer 2, use a color inkjet printing unit 9 loaded with oil-based resin ink to print the graphic layer 4, and then use a screen printer to print white or colorless primer off-line Layer 5, sprinkle the hot melt adhesive powder layer 6 when the primer layer 5 is not yet dry, make the hot melt powder adhere to the graphic ink, absorb the excess hot melt powder and dry it to complete the preparation of the inkjet printing hollow transfer film . When printing, put the hot melt adhesive powder layer 6 facing the fabric to be transferred, and heat and press at 130-180°C on the...
