[0021] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside" and "outside" indicate directions or positional relationships based on the directions or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention. Obviously, the embodiments described are only some embodiments of the present invention, rather than all embodiments.

[0022] like Figure 1 and Figure 2 As shown, the present application provides a wear-resistant thermal transfer lettering film, which includes a release film layer 1, a light-transmitting connecting layer 2, an adhesive layer 3, a supporting layer, a hot melt adhesive layer and a release film layer 4 in sequence. A printing layer 12 is provided on the side of the light-transmitting connecting layer 2 facing the adhesive layer. The light-transmitting connecting layer 2 is made of a waterproof and breathable polyurethane film to increase the air permeability of the lettering film, and the hot melt adhesive layer is formed of EVA hot melt adhesive.

[0023] When the lettering film needs to be transferred to clothing, tear off the release film layer 2 4, make one side of the hot melt adhesive layer of the lettering film close to the clothing, make the flat-plate thermal transfer machine contact the release film layer 1, apply heat and pressure to the lettering film, and use the heat and pressure to connect the hot melt adhesive layer to the clothing. After completion, release the contact between the flat-plate thermal transfer machine and the release film layer 1, tear off the release film layer 1, and complete the thermal transfer printing. People can see the printing layer 12 through the light-transmitting connecting layer 2, and finally transfer the pattern to the surface of the clothing to improve the aesthetics of the clothing.

[0024] like Figure 2 and Figure 3As shown, the support layer includes a molded layer 1 5, an adhesive layer 2 6 and a molded layer 2 7 in sequence. A plurality of convex columns 8 are formed on the side of the molded layer 1 5 away from the molded layer 1 5. The convex columns 8 and the molded layer 1 5 are formed by adding resin to the mold and curing them as a whole. After the molded layer 1 5, the adhesive layer 2 6 and the molded layer 2 7 are connected, they are punched by a thin film laser punching machine to form a plurality of ventilation ports 9. The ventilation ports 9 penetrate the molded layer 1 5, the adhesive layer 2 6 and the molded layer 2 7. The length of the ventilation ports 9 is The direction is consistent with the thickness direction of the lettering film, and the support layer is completed. Then, by coating the adhesive on the printing layer 12, the convex column 8 is brought into contact with the adhesive to form an adhesive layer 3, and the convex column 8 and the adhesive layer 3 are connected. Due to the support of the convex column 8, a plurality of air ducts 13 are formed between the molded layer 5 and the adhesive layer 3. The plurality of air ducts 13 are interconnected, and the length direction of the air duct 13 is perpendicular to the thickness direction of the lettering film, which also enables the ventilation port 9 to be connected with the air duct 13.

[0025] like Figure 2 and Figure 4 As shown, when the molded layer 2 7 is made, the resin is poured into another mold for solidification, so that a plurality of clearance grooves 10 are formed on one side of the molded layer 2 7. When the film is subsequently laser punched, the ventilation port 9 is formed at the center of the clearance groove 10. The clearance groove 10 is located at the opening edge of the ventilation port 9, and the hot melt adhesive layer includes a plurality of hot melt adhesive blocks 11. The plurality of hot melt adhesive blocks 11 are arranged in an array, and the hot melt adhesive blocks 11 are located between the plurality of ventilation ports 9. When the lettering film is transferred to clothing, the lettering film is subjected to heat and pressure. The heat softens the hot melt adhesive blocks 11, and the pressure squeezes the hot melt adhesive blocks 11, thereby causing deformation. The partially deformed position of the hot melt adhesive blocks 11 will enter the clearance groove 10, reducing the degree of diffusion of the hot melt adhesive blocks 11 to the surroundings, so that the hot melt adhesive blocks 11 are not easy to block the ventilation port 9, thereby ensuring that air can pass through the ventilation port 9.

[0026] After the lettering film is transferred and adhered to the clothing, the ventilation port 9 will press against the clothing. When the outside air flows through the air duct 13, the air flow speed in the air duct 13 will be accelerated and the air pressure will be reduced, so that the air flowing in the air duct 13 will drive the air flow in the ventilation port 9, so that the lettering film will inhale air through the clothing, thereby accelerating the ventilation effect here, reducing the airtight effect at the place blocked by the lettering film, and ensuring comfort.

[0027] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
