Description

Technical Field

[0001] The utility model belongs to the field of thermal sublimation transfer printing, and in particular relates to a flat plate type transfer ironing machine test structure which simulates white spots of a roller type transfer ironing machine. Background Art

[0002] Thermal sublimation transfer is a new process that uses an inkjet printer equipped with digital printing ink to print portraits, landscapes, texts and other images on transfer paper in a mirror image manner, and then heats it to about 200~220℃ through a thermal transfer device to make the thermal transfer ink on the paper sublimate and penetrate into the substrate, thereby realistically transferring the color image on the paper to the textile.

[0003] With the rapid development of thermal sublimation transfer technology, white spot problems are collectively referred to as the "cancer" of the industry. White spots refer to the uneven coloring of the sublimated dye on the substrate during thermal sublimation transfer. Some places on the substrate are not attached with dye, resulting in no color printed and appearing to have white spots. The defects caused by white spots in the thermal sublimation transfer process are directly transferred to the substrate through transfer, affecting the appearance and normal use. The transferred fabrics have to be scrapped, resulting in increased comprehensive costs and failure to deliver goods on time.

[0004] At present, the thermal sublimation transfer equipment used by manufacturers of thermal sublimation transfer paper and manufacturers that perform thermal sublimation transfer is different. Manufacturers are mainly paper companies. Thermal transfer is only used to test the transfer quality of the transfer paper produced by the factory, so smaller flat-bed transfer machines are usually used. Manufacturers that perform thermal sublimation transfer have larger outputs and usually use large-scale roller transfer equipment. The transfer effects of these two types of equipment are different. For the same transfer paper, there will be no white spots when the manufacturer tests the transfer on its own equipment, but white spots will appear during the actual production of the transfer manufacturer. This will cause the transfer paper manufacturer to be unable to make improvements and adjustments to the products it produces in a timely manner. If the manufacturer of transfer paper does not have transfer-related business, it is not cost-effective to introduce a large roller transfer machine. Utility Model Content

[0005] In order to solve the above problems, the utility model provides a flat plate transfer ironing machine test structure which simulates the white spots of a roller transfer ironing machine.

[0006] The purpose of the utility model is achieved in the following ways:

[0007] A flat-plate transfer ironing machine test structure simulating white spots of a roller transfer ironing machine includes a flat-plate transfer ironing machine, wherein the flat-plate transfer ironing machine includes a bottom plate, a heating plate, transfer paper and a substrate are arranged between the heating plate and the bottom plate, and an air-permeable carrier is arranged on the side of the transfer paper that does not contact the substrate, so that the number of white spots after transfer by the flat-plate transfer ironing machine is increased.

[0008] The flat-plate transfer ironing machine test structure simulating white spots of a roller transfer ironing machine, wherein the air permeable carrier is a fiber mat.

[0009] The flat-plate transfer ironing machine test structure simulating the white spots of the roller transfer ironing machine is arranged in the following order from top to bottom during transfer: heating plate, substrate, transfer paper, and fiber pad.

[0010] Compared with the prior art, the utility model changes the air permeability around the transfer paper so that the transfer effect on the flat-plate transfer ironing machine can be close to that of the roller transfer ironing machine, so that the white spots that originally appeared on the drum transfer ironing machine but could not appear on the flat-plate transfer ironing machine can also be transferred using the flat-plate transfer ironing machine, and the transfer paper manufacturers can adjust the process in time and improve the transfer paper.

[0013] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0015] A method for simulating white spots in roller transfer, including a heating plate 1, which increases the air permeability around the transfer paper in a flat-plate transfer, so that the number of white spots after the flat-plate transfer increases. When performing thermal sublimation transfer, the air permeability will affect the transfer effect. When the air permeability is high, it will disturb the sublimated dye, causing the sublimated dye to move and deviate from the original position. If there is no dye attached to the original position, white spots will be generated. Large transfer manufacturers usually use roller transfer for thermal sublimation transfer. The transfer environment is open and has good air permeability, so white spots are easy to generate. However, the flat-plate transfer is semi-closed during transfer, with poor air permeability, and it is not easy to disturb the dye, so white spots are not easy to appear. Therefore, when performing flat-bed thermal sublimation transfer, increasing the air permeability around the transfer paper can promote the movement of the dye after sublimation in the flat-bed thermal sublimation transfer, increase the white spots of the transfer, and make the transfer effect of the flat-bed transfer ironing machine close to that of the roller transfer ironing machine. The transfer effect of the flat-bed transfer ironing machine is actually better than that of the roller transfer ironing machine in terms of white spots, but it is not conducive to the transfer paper manufacturer's simulation of the actual transfer situation. The utility model is actually a degradation of the transfer effect of the flat-bed transfer ironing machine, and meets the actual needs by degrading the transfer effect.

[0016] The method for simulating the transfer of white spots by a roller transfer ironing machine, the flat-plate transfer ironing machine includes a bottom plate 4, a heating plate 5, and a transfer paper and a substrate are arranged between the heating plate 5 and the bottom plate 4. The method for increasing the air permeability around the transfer paper is to arrange an air-permeable carrier on the side of the transfer paper that does not contact the substrate. The original flat-plate transfer ironing machine is a heating plate on the top layer, the transfer paper is below the heating plate, the substrate is below the transfer paper, and the rubber pad is below the substrate. The heating plate is a metal plate with poor air permeability, so that the dye on the transfer paper is not easily disturbed after sublimation, and no white spots will appear.

[0017] In the method for simulating the transfer of white spots by a roller transfer ironing machine, the air permeable carrier is a fiber mat. The raw material of the fiber mat is close to paper, and can be replaced by wood pulp paper in the prior art, because ordinary wood pulp paper also has a certain thickness and air permeability, but the fiber mat of the present application that can reach a thickness of 95-115 μm and an air permeability of 2-6 μm / Pa·s is most preferred.

[0018] The method of simulating the transfer of white spots by a roller transfer ironing machine is described. The order of placement from top to bottom during transfer is: heating plate, substrate, transfer paper, fiber pad, bottom plate. The existing flat-plate thermal sublimation transfer is placed in the order of heating plate, transfer paper, and substrate. The advantage of this is that the heating plate directly contacts the transfer paper, which has a good heating effect on the dye. However, we need to add a fiber pad on the back of the transfer paper to increase the air permeability around the transfer paper. If it is directly added between the transfer paper and the heating plate, the fiber pad has good heat insulation ability and will affect the sublimation of the fuel. Therefore, the positions of the transfer paper and the substrate are exchanged, and the heat insulation ability of the substrate is much smaller than that of the fiber pad, which has less impact on the dye. Therefore, the order of placement during transfer in the utility model is heating plate, substrate, transfer paper, fiber pad, rubber pad, bottom plate. Among them, the rubber pad is a pad already available in the existing flat-plate transfer ironing machine, which is placed on the bottom plate to play a supporting role. As shown in Table 1 below, when there is no fiber pad, white spots cannot be transferred. Although the thermal insulation capacity of the substrate is less than that of the fiber mat, it will still affect the dye, causing the transfer rate to decrease. This problem can be solved by increasing the transfer time. For example, in Table 1, number 15 has a temperature of 220°C and a transfer time of 30s. The transfer is uniform and the white spots are obvious.

[0019]

[0020] In order to implement the above method, a flat-plate transfer ironing machine test structure simulating the white spots of a roller transfer ironing machine is provided, including a flat-plate transfer ironing machine, wherein the flat-plate transfer ironing machine includes a bottom plate 4, a heating plate 5, a transfer paper and a substrate are arranged between the heating plate 5 and the bottom plate 4, and a breathable carrier is arranged on the side of the transfer paper that is not in contact with the substrate, so that the number of white spots after transfer by the flat-plate transfer ironing machine is increased.

[0021] The flat-plate transfer ironing machine test structure simulating white spots of a roller transfer ironing machine, wherein the air permeable carrier is a fiber mat.

[0022] The flat-plate transfer ironing machine test structure simulating the white spots of the roller transfer ironing machine is arranged in the following order from top to bottom during transfer: heating plate, substrate, transfer paper, and fiber pad.

[0023] In the method for simulating the transfer of white spots by a roller transfer ironing machine, the fiber mat has a thickness of 95-115 μm and an air permeability of 2-6 μm / Pa·s. When the thickness is too thin, the air permeability is poor; when the thickness is too thick, the substrate and the transfer paper are subjected to greater pressure, which may cause deformation or damage of the substrate or the transfer paper, affecting the transfer effect. The air permeability of 2-6 μm / Pa·s is the transfer effect closest to that of a roller transfer ironing machine.

[0024] For the fiber mat with a mat thickness of 95-115 μm and an air permeability of 2-6 μm / Pa·s used in the above-mentioned method of simulating roller transfer printing of white spots, the utility model provides a fiber mat formula: 75% bleached conifer pulp (beating degree 60-80, beating concentration: 2.5-3.0%), 6% oxidized starch, 10% light calcium carbonate, 1.5% aluminum sulfate, 2.5% adhesive, 2% fiber dispersant, 3% acrylic latex. 120 g / T pulp beating enzyme is added during pulping. The fiber mat produced by this formula can meet the above requirements.

[0025] The above is only a preferred embodiment of the present invention. It should be pointed out that those skilled in the art can make several changes and improvements without departing from the overall concept of the present invention, and these should also be regarded as the protection scope of the present invention.
