In addition, the heat transfer film can also be used for elastic cloth, or the cloth can show special effects such as pearlescence and laser. There are also many methods for preparing hot stamping foils, but most of them are different.
Chinese patent CN208914824U provides a laser light-reflecting hot stamping foil for cloth, which comprises a BOPP (biaxially-oriented polypropylene) base film, wherein a laser layer and a light-reflecting layer are sequentially coated on the BOPP base film; wherein the thickness of the BOPP basal membrane is 20-25 μm, and the BOPP basal membrane with the thickness has high tensile strength, toughness and reflective dye wettability suitable for printing; the laser layer is a resin curing layer. The hot stamping foil has laser powder after being hot stamped, has the characteristic of flashing after being irradiated by light, and obviously improves the scratch resistance and the scuff resistance of the product; the reflective layer is formed by mixing and curing reflective dye and modified PU resin, so that the hot stamping foil can have different colors and has reflectivity; after the surface layer of the reflective fabric is subjected to hot stamping and heat transfer, the reflective fabric has the characteristics of flashing and light reflection after being irradiated by light, the attractiveness and comfort of the fabric are improved, and the service life of the fabric is prolonged.
Chinese patent CN211942664U provides an alumite hot stamping foil with controllable color development for hot stamping graphics, which comprises a layer of PET film substrate, wherein a hot stripping layer, an irreversible color layer, a resin cutting layer, an aluminum plating layer and a gum layer are sequentially arranged on the surface of the film substrate, and belongs to the technical field of coating and printing. The hot stamping picture and text can be displayed as silver color below 150 ℃, can irreversibly display hot stamping pictures and texts with different colors at a specific hot stamping temperature, and has the characteristics of controllable color development and good hot stamping slitting property.
Meanwhile, the company also applies for Chinese patent CN113580798A, which introduces a high-water-washing-resistance hot stamping foil for fabrics and a preparation process thereof, and belongs to the technical field of functional materials.
