Description

Technical Field

[0001] The present invention relates to the technical field of fabric production, and more particularly to a transfer sticker for fabric, a heat transfer method, a fabric, and a wearable article. Background Art

[0002] Lace fabric has a good aesthetic effect, so lace fabric is used in some women's underwear to make the underwear more popular with consumers. However, in the prior art, in order to achieve the effect of lace for underwear fabric, traditional embroidered lace is generally used. However, the fabric made by the embroidery method has no elasticity. The lace is formed by embroidery, and the color of the lace is changed by the color of the sewing thread. It has more thread ends and poor comfort when directly applied to close-fitting clothes. On the other hand, the elastic process of traditional lace fabric uses elastic thread material to weave a flower blank in a weaving form, then dyeing, ironing and shaping, cutting, and finally combining with traditional fabric to form a finished garment. The whole process requires more manual operations. Therefore, the existing lace-effect fabrics have relatively large process limitations for products, especially low efficiency in large-scale production, and high defective product rates due to many manual processes during production. The elastic performance is greatly restricted by the material of the thread. Summary of the Invention

[0003] The present invention discloses a transfer sticker for fabric, aiming to improve the problems of low production efficiency and poor elasticity of the existing fabric with lace effect.

[0004] The present invention adopts the following solutions:

[0005] The present application provides a transfer sticker for fabric, including: a film substrate, on which a transfer layer is detachably provided, and the transfer layer at least includes:

[0006] A first adhesive layer, which is disposed above the film substrate and is adapted to bond with the fabric during the transfer process;

[0007] A graphic information bearing layer, which is an elastic gel and is at least partially disposed on the first adhesive layer and forms a specific graphic information or color above the film substrate;

[0008] A second adhesive layer, which is at least partially disposed on the graphic information bearing layer and is used to bond another fabric.

[0009] Further, the first adhesive layer, the graphic information bearing layer, and the second adhesive layer are arranged in the style of the specific graphic information so that the remaining area of the fabric can breathe.

[0010] Further, a filling foaming agent is mixed into the elastic glue of the graphic information bearing layer to form the 3D specific graphic information, and an adhesive ring is provided along the contour of the specific graphic information so that the foaming agent bulges longitudinally along the fabric to form a 3D graphic and the upper and lower fabrics are not easily separated under an external force.

[0011] Further, a colorant is filled into the elastic glue to form a specific color.

[0012] Further, at least one of the two fabrics is a transparent fabric so that the specific graphic information or color can be shown through the transparent fabric.

[0013] Further, silicone oil layers are provided on both the upper and lower surfaces of the diaphragm substrate to facilitate the peeling of the transfer layer from the diaphragm substrate and prevent the bonding of the transfer layer with the transfer layer of another transfer sticker.

[0014] Further, the first adhesive layer, the graphic information bearing layer, and the second adhesive layer are all formed on the diaphragm substrate by screen printing.

[0015] The present invention also provides a heat transfer method for fabrics, using the transfer sticker for fabrics described in any one of the above, including the following steps:

[0016] S1. Unfold the first fabric;

[0017] S2. Place the transfer layer of the transfer sticker on the first fabric so that the second adhesive layer contacts the first fabric;

[0018] S3. Press the first fabric and the transfer sticker together through a hot press device so that the second adhesive layer adheres to the first fabric;

[0019] S4. Peel the diaphragm substrate from the transfer sticker;

[0020] S5. Unfold and place the second fabric above the first adhesive layer;

[0021] S6. Press the second fabric and the first fabric together through a hot press device so that the first adhesive layer adheres to the second fabric.

[0022] The present invention also provides a fabric manufactured by the heat transfer method for fabrics described above.

[0023] The present invention also provides a wearable article, including the fabric described above.

[0024] Beneficial effects:

[0025] The present invention sets a heat transfer sticker for processing fabrics, and transfers the elastic layer with lace to the fabric by heat transfer, thereby forming a fabric with a graphic information bearing layer. The fabric made by this method will not produce thread ends, and can be directly combined with the fabric, and then cut to make the finished product, without dyeing, shaping, etc., which can simplify the process and save water resources. At the same time, the transfer sticker is formed by screen printing, which greatly improves the forming efficiency of the lace of the elastic layer, and then the multi-layer fabric is formed by heat transfer, so that the production efficiency of the fabric is greatly improved, without embroidery, splicing and other processes, and can be made into a certain shape and shape pattern, especially a close-fitting garment with a lace effect, in combination with a cup and other structures.

[0032] Example 1

[0033] Combination Figures 1 to 2 As shown, this embodiment provides a transfer sticker for fabrics, comprising: a film substrate 1, on which a transfer layer is releasably provided, and the transfer layer at least comprises:

[0034] A first adhesive layer 2, disposed above the film substrate 1, and suitable for bonding with the fabric during the transfer process;

[0035] A graphic information bearing layer 3, which is an elastic colloid and is at least partially disposed on the first adhesive layer 2 and forms specific graphic information or color on the film substrate 1;

[0036] The second adhesive layer 4 is at least partially disposed on the graphic information bearing layer 3 for bonding another piece of fabric.

[0037] In this embodiment, the diaphragm substrate 1 can be made of a plastic sheet, such as PET material. The transfer layer can be printed above the diaphragm substrate 1. Of course, the material of the diaphragm substrate 1 is not limited thereto. In a preferred embodiment, silicone oil layers are provided on both the upper and lower surfaces of the diaphragm substrate 1. The silicone oil layers can be coated on the diaphragm substrate 1 by an extruder. The purpose of providing the silicone oil layers in this embodiment is that during hot pressing, the transfer layer can be smoothly bonded to the fabric without being thermoset on the diaphragm substrate 1 due to heat, achieving the effect of improving the peeling performance. Here, the silicone oil layers are coated on both sides of the thin film substrate because during large-scale production, when multiple transfer stickers are stacked or rolled up together, when the quantity is large, a certain pressure will be generated, which easily causes the transfer layer of an adjacent transfer sticker to bond to the diaphragm substrate 1 of another transfer sticker, resulting in damage to the transfer sticker and inability to achieve automated production. By providing silicone oil layers on both sides, on the one hand, it can improve the peeling efficiency of the transfer layer from the diaphragm substrate 1 during heat transfer printing on the fabric, and on the other hand, it can prevent the heat transfer layer from sticking to the diaphragm substrate 1 during hot pressing or large-scale production.

[0038] In this embodiment, the first adhesive layer 2 and the second adhesive layer 4 are used to bond the graphic information bearing layer 3 to the fabrics on both sides, thereby fixing the graphic information bearing layer 3 between two layers of fabric. Here, the first adhesive layer 2 and the second adhesive layer 4 can be made of hot melt adhesive, but are not limited thereto, and other transparent adhesive materials can also be used. In one embodiment, the first adhesive layer 2 is printed on the diaphragm substrate 1 by screen printing, and then the graphic information bearing layer 3 is also printed on the first adhesive layer 2 by screen printing, so that one side of the graphic information bearing layer 3 is fixed on the first adhesive layer 2. Then, the second adhesive layer 4 is printed on the other side of the graphic information bearing layer 3 by screen printing. After cooling, the transfer layer is formed, thus jointly forming an independent transfer sticker with the diaphragm substrate 1, which can be used to transfer the heat transfer layer to the fabric. Here, the shapes of the first adhesive layer 2 and the second adhesive layer 4 are the same as the shape of the graphic information bearing layer 3. In this embodiment, the first adhesive layer 2 and the second adhesive layer 4 are at least partially disposed on the graphic information bearing layer 3, including partial mixing and overlapping of the first adhesive layer 2 and the second adhesive layer 4 with the graphic information bearing layer 3, and also including fixed bonding of the first adhesive layer 2 and the second adhesive layer 4 with the graphic information bearing layer 3.

[0039] Combined Figure 2 and Figure 3As shown, in this embodiment, the graphic information bearing layer 3 is disposed between the first adhesive layer 2 and the second adhesive layer 4. Here, the graphic information bearing layer 3 can be made of polyurethane material, which has a good elastic effect and is elastic in all directions. When it is transferred to the fabric, it can be pulled together with the fabric in the circumferential direction, that is, it has elastic properties in all directions. Here, the graphic information bearing layer 3 can be transferred to the first adhesive layer 2 by screen printing. In one embodiment, the graphic information bearing layer 3 can have different colors. For example, different colorants can be added to achieve different color effects. Since the first adhesive layer 2 and the second adhesive layer 4 are transparent hot melts, they will not cover the color of the graphic information bearing layer 3. Here, the graphic information bearing layer 3 can be provided with various lace pattern shapes, which can be characters, patterns, logos, etc. At the same time, due to the lace pattern design, there are many gaps on the graphic information bearing layer 3, which can make the fabric have a good air permeability effect when transferred to the fabric. That is, in one embodiment, there are many gaps or holes in the graphic information bearing layer 3. The gaps or holes can be naturally formed during the lace design process. The first adhesive layer 2, the graphic information bearing layer 3, and the second adhesive layer 4 are arranged in the style of the specific graphic information so that the remaining area of the fabric can be breathable. The remaining area of the fabric described in this embodiment includes the gaps or holes, and the area within the pattern range of the graphic information bearing layer 3. In the remaining part, the two fabrics can be not fixedly connected, or the specific parts can be fixed by sewing threads, or the two layers of fabrics can be connected at specific parts by hot melt adhesive.

[0040] In another embodiment, filling pigments or foaming agents can be mixed in the graphic information bearing layer 3. By mixing pigments, the color of the graphic information bearing layer 3 can be changed. Through additives such as foaming agents and fluorescent powders, different effects can be achieved on the graphic information bearing layer 3, such as 3D effects, fluorescent effects, etc. And since the pigments and foaming agents are covered by the first adhesive layer 2 and the second adhesive layer 4, after the fabric is made, it will not fade during the washing process, nor will there be a problem of deterioration due to contact with water. Preferably, since the strength inside the foaming layer is low and it is easily torn during pulling, on the graphic information of the graphic information bearing layer 3, an adhesive ring is provided along the contour of the specific graphic information so that the foaming agent bulges longitudinally along the fabric to form a 3D graphic and the upper and lower fabrics are not easily separated under the action of external forces. That is, here, through the adhesive ring, the connection strength of the foaming position can be improved in the foaming part. At the same time, due to the effect of the surrounding ring, the foaming agent can only bulge in the longitudinal direction of the two fabrics and will not extend horizontally, thereby improving the 3D effect.

[0041] In this embodiment, through the transfer layer arranged in multiple layers, when transferred onto the fabric, it is located between two fabrics and forms a fabric with a 3D lace effect together with the fabric. It can be used to make wearable clothes, etc. When combined with an ultra-thin elastic fabric, the fabric can have a visible lace effect, producing the same aesthetic effect as the existing lace, and at the same time having high multi-directional elasticity. When applied to an underwear, in cooperation with the cup, it can be integrally fixed on the surface of the cup without using a splicing method, and the underwear has good elastic performance.

[0042] Embodiment 2

[0043] Combined with Figures 3 to 5 As shown in the figure, the embodiment of the present invention also provides a heat transfer method for fabrics. Using the transfer sticker for fabrics described above, it includes the following steps:

[0044] S1. Unfold the first fabric 5 on the base surface;

[0045] S2. Place the transfer sticker on the first fabric 5 so that the second adhesive layer 4 contacts the first fabric 5;

[0046] S3. Press and bond the first fabric 5 and the transfer sticker through a hot press device so that the second adhesive layer 4 is pasted on the first fabric 5;

[0047] S4. Peel the film substrate 1 from the transfer sticker;

[0048] S5. Unfold and place the second fabric 6 above the first adhesive layer 2;

[0049] S6. Press and bond the second fabric 6 and the first fabric 5 through a hot press device so that the first adhesive layer 2 is pasted on the second fabric 6.

[0050] In the above embodiment, at least one of the first fabric 5 and the second fabric 6 is made of an ultra-thin elastic fabric, such as the existing skin-friendly ultra-thin swim fabric, ultra-thin perforated fabric, elastic fabrics such as nylon, polyester fiber, cotton, etc. In the above steps, the hot pressing temperature is between 150° and 210°, and the temperature of the first hot pressing is lower than that of the second hot pressing. For example, the temperature of the first hot pressing is 170°, and the temperature of the second hot pressing is 190°. The temperature of the second hot pressing is higher than that of the first hot pressing because the fabric is formed during the second hot pressing. Therefore, the fabric can remelt the first adhesive layer 2 of the first hot pressing to ensure the bonding effect between the first fabric 5, the second fabric 6 and the transfer layer. During the hot pressing process, since the hot melt adhesive melts, it will penetrate into the interior of the fabric under the action of pressure, thus ensuring the connection effect between the transfer layer and the fabric.

[0051] When the fabric is produced by the above method, automated production can be achieved. And by means of heat transfer, each time only the transfer layer needs to be heat-transferred onto the fabric, which greatly improves the speed of pattern drawing on the fabric. Moreover, through the solution of this embodiment, the fabric can have the effect of 3D lace and at the same time has good elasticity.

[0052] Embodiment 3

[0053] An embodiment of the present invention provides a fabric, which is made by the above-mentioned heat transfer method for fabrics. The fabric made by the above solution has good elasticity and good aesthetic effect. Compared with the existing lace fabrics, it has no loose threads, and a skin-friendly fabric can be used as the bottom layer. The requirements for the wire are low, and there is no need for processes such as dyeing and shaping. It has a high environmental protection level and no harm to the human skin, greatly improving the user experience.
