Description

Technical Field

[0001] The invention belongs to the technical field of thermal transfer paper, and specifically relates to an instant-dry thermal transfer paper based on elastic fabric and a preparation method thereof. Background Art

[0002] Thermal transfer paper is a special printing material used in thermal transfer technology, usually used to print patterns, text and logos on the surface of textiles, ceramics, metals, plastics, wood and other objects. Its main components are paper, coatings, thermosensitive adhesives and printing inks, among which coatings and thermosensitive adhesives are the key components of thermal transfer paper. There is also an instant-dry thermal transfer paper in thermal transfer paper, which is a thermal transfer paper that does not need to wait for drying. It uses a special thermosensitive adhesive that can produce a strong bonding effect with the surface of clothing or other items while hot pressing. Compared with traditional thermal transfer paper, it does not need to wait for drying, has strong adhesion, bright colors and low cost. It is widely used in clothing, shoes and hats, luggage, home furnishings and other fields. It is an efficient and practical thermal transfer material.

[0003] Although common instant-dry thermal transfer paper can achieve quick drying, there are still certain problems in actual use. For example, thermal transfer paper is limited by its own material, resulting in its own poor elasticity and softness, which will lead to a decrease in the quality of the printed pattern. When the thermal transfer paper is not soft enough, it cannot be flatly attached to the surface of some objects, causing the details and contours of the pattern to be distorted or blurred. In addition, if the elasticity is insufficient, the thermal transfer paper may fall off or tear after use, which will shorten the life of the printed product and affect the appearance of the product. Therefore, it is crucial to solve the problem of insufficient elasticity and flexibility of thermal transfer paper. Summary of the invention

[0004] The object of the present invention is to provide an instant-drying thermal transfer paper based on elastic fabric and a preparation method thereof, so as to solve the problems raised in the above-mentioned background technology.

[0005] In order to achieve the above-mentioned purpose, the present invention provides the following technical solutions: an instant-drying thermal transfer paper based on elastic fabric and a preparation method thereof, comprising a thermal transfer paper substrate, the top of the thermal transfer paper substrate is provided with completely penetrating limit grooves at equal distances, the upper and lower ends of the thermal transfer paper substrate are provided with elastic fabrics, the two ends of the elastic fabrics that are relatively far away are provided with adhesive layers, the two ends of the adhesive layers that are relatively far away are provided with protective layers, and the ends of the two elastic fabrics that are relatively close to each other are fixedly installed with limit strips at equal distances.

[0006] As a further technical solution of the present invention, the thermal transfer paper substrate is made of polyethylene terephthalate or elastic polyester, the number of the limiting grooves is the same as the number of the limiting strips, and the cross-sectional area of ​​the limiting grooves is the same as the cross-sectional area of ​​the limiting strips.

[0007] As a further technical solution of the present invention, the elastic fabric is connected through a limit strip and a limit groove, the limit strips at one end of the upper and lower elastic fabrics are in contact with each other, the upper and lower ends of the thermal transfer paper substrate are adhered to the elastic fabric through a thermosensitive adhesive, and the elastic fabric is made of one of elastic polyester, elastic polyurethane, and elastic nylon.

[0008] The thermal transfer paper substrate made of PET has good heat resistance and can withstand higher temperatures. At the same time, the coating on its surface can prevent moisture from penetrating, preventing the color and quality of the pattern from being affected. It can also resist the erosion of organic solvents such as strong acids and alkalis, and is easy to process. At the same time, the thermal transfer paper substrate made of elastic polyester material has good elasticity and softness while having the above advantages. It can adapt to different bending and stretching deformations, so it is suitable for thermal transfer elastic fabrics. The addition of elastic fabrics can significantly improve the softness and elasticity of the thermal transfer paper, so that it can adapt to the deformation of objects or fabrics of different shapes, thereby improving the quality and aesthetics of the thermal transfer pattern.

[0009] As a further technical solution of the present invention, the adhesive layer is made of elastic coating and the elastic coating is one of acrylic emulsion, polyurethane, styrene-butadiene rubber emulsion and silicone rubber.

[0010] As a further technical solution of the present invention, the protective layer is made of silicone oil paper or polyester film, and the protective layer is adhered to the elastic fabric through an adhesive layer. The cross-sectional area of ​​the protective layer, the elastic fabric and the thermal transfer paper substrate is the same.

[0011] By adding an adhesive layer to the thermal transfer paper, the flexibility and elasticity of the thermal transfer paper can be enhanced, making it more suitable for printing and thermal transfer of elastic fabrics. The adhesive layer can form a soft film layer on the surface of the thermal transfer paper, so that the surface of the thermal transfer paper has better elasticity and scalability, and can better adapt to the deformation of the elastic fabric. At the same time, the adhesive layer can also improve the wear resistance and durability of the thermal transfer paper, making the printed pattern more durable and firm. A protective layer is added to the upper and lower ends of the thermal transfer paper to protect the edges of the thermal transfer paper from damage, while also maintaining the flatness of the thermal transfer paper to ensure printing quality.

[0012] A method for preparing instant-drying thermal transfer paper based on elastic fabric, comprising the following method:

[0013] S1: First, a substrate made of polyethylene terephthalate or elastic polyester is selected as the basic material of the thermal transfer paper substrate, and the thermal transfer paper substrate is laid flat on a workbench. At the same time, a flattening machine or a flat plate can be used to flatten the thermal transfer paper substrate to ensure that there are no wrinkles or bends on the surface of the thermal transfer paper substrate. At the same time, an elastic fabric made of one of elastic polyester, elastic polyurethane, and elastic nylon and a silicone oil paper or polyester film are prepared to form a protective layer;

[0014] S2: After the preparation of the thermal transfer paper substrate is completed, the surface of the thermal transfer paper substrate needs to be cut at equal distances by a slotting machine to cut it into corresponding limiting grooves, and ensure that the size of each limiting groove is exactly the same, and at the same time ensure that the distance between every two limiting grooves is exactly the same, so as to complete the slotting of the thermal transfer paper substrate;

[0015] S3: evenly apply the thermosensitive adhesive on the upper and lower ends of the thermal transfer paper substrate, and use a coating machine to evenly apply the thermosensitive adhesive on the surface of the thermal transfer paper substrate to form a film with uniform thickness, and before the thermosensitive adhesive is dried, place two elastic fabrics on the upper and lower ends of the thermal transfer paper substrate, and at the same time, clamp the limiting strip at one end of the elastic fabric with the limiting groove to ensure that the limiting strips between the upper and lower elastic fabrics are in contact with each other, so as to complete the lamination of the elastic fabric and the thermal transfer paper substrate;

[0016] S4: After the elastic fabric and the thermal transfer paper substrate are bonded, the upper and lower surfaces can be flattened by a flattening machine to ensure that there are no wrinkles or bubbles on the surface, so that it fits tightly with the thermal transfer paper substrate. After the thermal adhesive is completely dry, apply the adhesive layer;

[0017] S5: Apply an adhesive layer made of elastic coating on the surfaces of the upper and lower elastic fabrics, and make it completely cover the surface of the elastic fabrics to form a certain film, and evenly cover the adhesive layer on the surface of the elastic fabrics through a coating machine, and select a protective layer made of silicone oil paper or polyester film to fit it to the elastic fabrics;

[0018] S6: Use a flattening machine to flatten the surface of the protective layer to ensure that the surface of the protective layer is wrinkle-free and relatively flat. After flattening, place the thermal transfer paper in a high temperature and high pressure environment and wait for the adhesive layer to completely solidify to complete the processing;

[0019] S7: Cut the processed thermal transfer paper into corresponding sizes and shapes according to size requirements, trim and sort out the impurities on its edges, and store the processed thermal transfer paper in a dry and ventilated place to complete the preparation process.

[0020] As a further technical solution of the present invention, the thermal transfer paper substrate can be flattened by a flattening device when flattening. When flattening, the thermal transfer paper substrate needs to be placed on a flat workbench, and the heat press is preheated to a suitable temperature, and a suitable pressure is selected to heat press the thermal transfer paper substrate. After the heat pressing is completed, it needs to be placed on a flat surface to avoid folding or squeezing.

[0021] By flattening the thermal transfer paper substrate before processing, it can be ensured that there are no wrinkles or bubbles on the surface of the processed thermal transfer paper, which significantly improves the quality of the thermal transfer paper.

[0022] As a further technical solution of the present invention, when applying the thermosensitive adhesive, the thermosensitive adhesive needs to be poured into a coater, and the adhesive is evenly coated on the surface to be bonded through the roller of the coater, and the coating thickness and speed are precisely controlled by the coater to ensure the uniformity of the coating.

[0023] By controlling the thickness and uniformity of the thermal adhesive, it can achieve precise bonding, while reducing the impact of the unevenness of the thermal adhesive on the flatness and elasticity of the thermal transfer paper, thereby improving the overall quality.

[0024] The beneficial effects of the present invention are as follows:

[0025] The present invention provides a limiting groove on the surface of the thermal transfer paper substrate so that the thermal transfer paper can collapse to a certain extent when it is deformed, that is, when it is bent, it can adapt to the shape of the curved surface, provide a better fitting effect, and meet the printing requirements of the thermal transfer paper. The thermal transfer paper substrate made of elastic polyester can also improve the overall elastic performance of the thermal transfer paper, and the cooperation between the limiting groove and the limiting strip can assist in the positioning of the layers during the processing process to meet the fitting requirements. At the same time, the elastic material of the elastic fabric and the adhesive layer can further improve the elasticity of the thermal transfer paper, and the protective layer can significantly protect the edge and surface of the thermal transfer paper, so that it has good heat resistance and durability, can withstand high temperatures and resist the erosion of organic solvents, and significantly improves the performance of the thermal transfer paper. The application of the above-mentioned thermal transfer paper can provide better elastic properties, durability and printing effects, while reducing usage restrictions and costs, bringing more innovation and development opportunities to the thermal transfer industry.
