[0002] In the thermal transfer industry, for example, heat transfer efficiency (or heat transfer efficiency) is a key factor affecting production efficiency and production costs. Improving production efficiency and reducing unit energy consumption are one of the goals of the industry. Taking the thermal transfer printing process as an example, thermal transfer printing is one of the textile printing methods. First, the pattern is printed on paper with ink or ink containing disperse dyes, and then the transfer paper and the white cloth are attached together through the thermal transfer printing machine. The machine is operated at a temperature of 210-235℃. The dye on the transfer paper sublimates and transfers to the fabric at high temperature to complete the fabric printing.

[0003] Existing thermal transfers are all heated by electric energy, which is a serious power-consuming device. Generally, the power used is 65kW-135kW. The transfer of heat energy basically relies on the heat conduction of the hot roller wall to the transfer paper, and then the transfer paper transfers the dispersed dye to sublimate the dye to achieve the purpose of dye migration. However, in this mode, due to the low thermal conductivity of the paper, the efficiency of heat energy driving dye migration is low and the transfer speed is slow, resulting in extremely high energy consumption of the equipment.

BRIEF DESCRIPTION OF THE DRAWINGS

[0026] Figure 1 The figure shows a comparison of the effects of the transfer fabric product of the present invention and the transfer fabric product of the prior art, wherein the fabric on the left is the transfer fabric product of the present invention. DETAILED DESCRIPTION

[0027] In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the specific implementation methods of the present invention will be described below with reference to the accompanying drawings. Obviously, the accompanying drawings described below are only some embodiments of the present invention. For ordinary technicians in this field, other drawings and other implementation methods can be obtained based on these drawings without creative work.

[0028] The present invention proposes a production method for improving heat transfer efficiency, which is applicable to the existing thermal transfer process. For the convenience of description, the present invention takes the thermal transfer printing process as an example for detailed description. It is easy to understand that the present invention can also be applied to other thermal transfer processes.

[0029] A production method for improving the efficiency of thermal transfer printing is to improve the transfer roller and / or blanket, and the specific method is as follows:

[0030] The invention improves the transfer roller by covering the surface of the transfer roller with a coating, and improves the heat transfer mode of heat transfer printing from conventional heat conduction to heat radiation as the main method and heat conduction as the auxiliary method, thereby improving the heat transfer efficiency and the transfer speed, thereby greatly reducing energy consumption.

[0031] The coating is formed by coating a mixture on the surface of a transfer roller. The mixture includes graphene, tetraethoxysilane (TEOS), N,N-dimethylformamide (DMF) and a promoter. After the above raw materials are mixed to form a mixture, the mixture is evenly coated on the transfer roller to form a leveled film. The transfer roller is heated to form a ceramic graphene coating on the mixture. The graphene is tightly adhered to the surface of the transfer roller.

[0032] Specifically, in the mixture, the mass fraction of graphene is greater than 0% and less than or equal to 20%, such as 1%, 2%, 3%, 4%, 5%, 6%, 7%, 8%, 9%, 10%, 11%, 12%, 13%, 14%, 15%, 16%, 17%, 18%, 19%, 20%, preferably, the mass fraction of graphene is 10-20%, graphene plays a role in enhancing thermal radiation, and the content of graphene cannot be too high, otherwise it will cause the hardness of the graphene coating to decrease significantly; the mass fraction of TEOS is 50-70%, such as 50%, 51%, 52%, 53%, 54%, 55%, 56%, 57%, 58%, 59%, 60%, 61%, 62%, 63%, 64%, 65%, 66%, 67%, 68%, 69%, 70%, TEOS at higher temperature conditions Under the condition of heat transfer printing, a ceramic structure of silicon dioxide material will be generated, so that the graphene coating has wear resistance and hardness; the mass fraction of DMF is 15-35%, such as 15%, 16%, 17%, 18%, 19%, 20%, 21%, 22%, 23%, 24%, 25%, 26%, 27%, 28%, 29%, 30%, 31%, 32%, 33%, 34%, 35%, and the role of DMF is to improve the bonding force between the graphene coating and the iron transfer roller, so that the coating will not be separated from the transfer roller during the thermal transfer printing process; the mass fraction of the promoter is 1-5%, such as 1%, 2%, 3%, 4%, 5%, and the role of the promoter is to improve the dispersibility of graphene in the mixture. Preferably, the promoter in the present invention is sodium hypochlorite, which has a better effect of promoting the dispersion of graphene and is easily decomposed under high temperature conditions.

[0033] Furthermore, the heating process after coating the mixture on the surface of the transfer roller is as follows: after the mixture is leveled on the surface of the transfer roller, the temperature of the transfer roller rises to 60-70°C so that the mixture stops flowing, and the temperature is continued to rise to 110-120°C to allow the volatile components in the mixture to evaporate, and the temperature is kept at this temperature for 30-50 minutes to allow the mixture to dry slowly without cracking, and then the temperature is slowly raised to 200°C. During the heating process, TEOS is gradually converted into a ceramic structure and the mixture is completely dried.

[0034] Before the mixture is coated on the surface of the transfer roller, the mixture can also be mixed with a diluent, which dilutes the mixture as a whole so that the mixture can be stably leveled on the roller surface. The diluent is a volatile organic solvent that does not react with other components of the graphene mixture. For example, the diluent can be an organic solvent such as ethanol, ethylene glycol or acetone. During the heating process, the diluent completely evaporates.

[0035] In the present invention, the thickness of the coating has no direct relationship to the effect of enhancing thermal radiation. It is easy to understand that the graphene needs to completely cover the surface of the transfer roller. In theory, the thickness of the coating is the thickness of a layer of carbon atoms. Under the premise of saving costs, the thickness of the coating is greater than or equal to 0.01 mm. For example, the thickness of the coating is 0.01 to 0.02 mm.

[0036] Furthermore, the improvement of the transfer roller of the present invention also includes coating an auxiliary thermal insulation layer on both ends of the transfer roller. The function of the auxiliary thermal insulation layer is to limit the heat radiation and heat conduction of the transfer roller to the outside world. When used in conjunction with the coating, the heat energy generated at the transfer roller is mainly transferred directly to the dye of the transfer paper in the form of thermal radiation, thereby increasing the sublimation rate of the dye.

[0037] Specifically, the auxiliary insulation layer is formed by coating an insulation mixture on the end of the transfer roller. The insulation mixture includes glass beads and polysilazane. The glass beads play an insulation role and the polysilazane has high viscosity, so that the glass beads are firmly adhered to the end of the transfer roller.

[0038] In the heat preservation mixture, the mass fraction of glass microspheres is 25-40%, such as 25%, 26%, 27%, 28%, 29%, 30%, 31%, 32%, 33%, 34%, 35%, 36%, 37%, 38%, 39%, 40%, 41%, 42%, 43%, 44%, 45%, and the mass fraction of polysilazane is 60-75%, such as 60%, 61%, 62%, 63%, 64%, 65%, 66%, 67%, 68%, 69%, 70%, 71%, 72%, 73%, 74%, 75%. Preferably, the mass fraction of glass microspheres is 30%, and the mass fraction of polysilazane is 70%.

[0039] The function of the auxiliary insulation layer is to reduce energy loss, make the temperature at both ends and in the middle of the transfer roller surface close and stable, reduce the heat radiation of the transfer roller to the frame, and also help to reduce the ambient temperature of the electromechanical equipment and provide protection against temperature loss caused by high-speed transfer.

[0040] The improvement of the thermal transfer blanket of the present invention is that a heat preservation layer is arranged on the surface of the thermal transfer blanket to intercept the heat energy transferred by the transfer roller during the transfer printing process, thereby effectively reducing the heat loss.

[0041] The heat-insulating layer is formed by spraying a dispersion on the surface of the thermal transfer blanket. The dispersion includes glass beads, water and a non-ionic surfactant. The above raw materials are mixed to prepare a dispersion, and the dispersion is sprayed on the surface of the thermal transfer blanket.

[0042] Specifically, in the dispersion, the mass fraction of glass beads is 3-5%, such as 3%, 3.5%, 4%, 4.5%, and 5%, and the glass beads are the main component of thermal insulation; the mass fraction of non-ionic surfactant is 6-15%, such as 6%, 7%, 8%, 9%, 10%, 11%, 12%, 13%, 14%, and 15%, and the role of non-ionic surfactant is to enable the glass beads to adhere to the surface of the thermal transfer blanket for a long time; the mass fraction of water is 80-90%, such as 80%, 81%, 82%, 83%, 84%, 85%, 86%, 87, 88%, 89%, and 90%, and the role of water is to make the dispersion form a suspension, which is convenient for spraying it on the surface of the thermal transfer blanket. During the production process, water evaporates and leaves the thermal transfer blanket, and the glass beads and non-ionic surfactant remain on the surface of the thermal transfer blanket to play a role in thermal insulation.

[0043] Preferably, the nonionic surfactant of the present invention includes one or two of glycerol and polyvinyl alcohol (PVA), more preferably, the nonionic surfactant includes glycerol and polyvinyl alcohol (PVA), wherein the mass fraction of glycerol is 5-10%, such as 5%, 6%, 7%, 8%, 9%, 10%, and the mass fraction of PVA is 1-5%, such as 1%, 2%, 3%, 4%, 5%.

[0044] The dispersion spraying covers greater than or equal to 80% of the surface area of ​​the thermal transfer blanket. More specifically, based on the mass of the glass beads, the spraying amount of the dispersion is greater than or equal to 20g / ㎡, that is, the mass of the glass beads sprayed per square meter on the surface of the thermal transfer blanket is greater than or equal to 20g, for example, the spraying amount is 20-50g / ㎡, and more preferably, the spraying amount of the dispersion is 30g / ㎡.

[0045] In the present invention, only the coating or only the insulation layer can achieve the effect of efficient production, wherein the graphene coating is to enhance the heat radiation capacity, and the insulation layer is to limit the heat radiation and minimize the heat energy loss. When the graphene coating and the insulation layer are used at the same time, the speed of dye sublimation on the transfer paper can be greatly increased, the thermal transfer efficiency can be effectively improved, and the energy consumption can be further reduced. Moreover, the printed fabric products made by the present invention have a pattern clarity and a color vividness that are significantly better than those made by the prior art. Figure 1 shown.
