Description

DETAILED DESCRIPTION OF THE INVENTION <<Industrial Application Field>> This invention relates to a heat-reversible flocked transfer fabric that is convenient to use.

<<Prior art>> Conventionally, many materials including felt fabric and melton fabric have been used as mark fabrics for forming required designs or letters by cutting out or punching, but in principle, the following two materials are used: It is processed and used by two means.

That is, use scissors, a knife, a mold, etc., to cut out the desired design or letters from felt fabric, melton fabric, or other materials, then punch them out and place them on the back, chest, arms, or other necessary places of the shirt by hand or with a sewing machine. It is a method of sewing on mark fabrics, or it is a method of attaching hot melt resin or film to one side of the mark fabric material by heat and cutting or punching it into the required design or character shape, and applying heat to the mark fabric by applying heat to the material such as a shirt. There is known a method of melting the bonded hot melt resin and bonding the mark.

Further, as shown in FIG. 17, a temporary adhesive layer 21 is applied to an opaque release material 20 using a heat reversible flocked transfer material.
The short fibers 22 are temporarily attached to the temporary adhesive layer 2 with high density to form the flocked layer 23, and the flocked layer 23 is
Apply a pattern adhesive layer 2 on top with strong adhesive.
4 is provided, and a hot melt resin layer 25 is further fixed on the pattern adhesive layer 24 (Japanese Patent Publication No. 53-35619, Japanese Unexamined Patent Publication No. 52-1982).
(Refer to Publication No. 155270).

≪Problems to be solved by the invention≫ By the way, in the former method, the markings in the form of patterns or letters are sewn around the marks regardless of their size, so it takes time and effort to use multiple patterns or letters such as people's names. In addition, it is extremely inefficient and has problems in terms of aesthetics and texture, as it takes time and there are individual differences in the sewing technique. The hot melt resin film is melted by heat and pressure and adhered to the shirt, etc., but since the hot melt resin melts and flows into the mark fabric material,
There were drawbacks such as hardening of the mark fabric material, impairing its elasticity and significantly inhibiting its feel.

Further, as shown in FIG. 17, a temporary adhesive layer 21 is applied to the release base fabric 20 using a heat reversal type flocked transfer fabric, and the short fibers 22 are densely flocked to the temporary adhesive layer 2 to form a flocked layer 23. In addition, a pattern adhesive layer 24 with a pattern is provided on the flocked layer 23 with a strong adhesive, and a hot melt resin layer 25 with a pattern is further fixed on the pattern adhesive layer 24. Since the patterned adhesive layer 24 and the patterned hot melt resin layer 25 are provided and cannot be cut out with scissors or the like, the user cannot freely select the shape and color of the mark, and it is difficult to transfer the desired shape of the mark. It is not possible. Also, opaque release material 2
By providing the temporary adhesive layer 21 on the 0, when transferring, it is not possible to sufficiently consider the orientation of the pattern adhesive layer 24 of the pattern to be transferred and the clothing to be transferred before pasting, making it unsuitable. There is a risk that the pattern adhesive layer 24 may be transferred and spoil the high-quality clothing, and furthermore, the hot melt resin layer 2 may be transferred.
5 is slippery, and if you apply a transfer device such as an iron from above and press it during transfer, the fabric surface of the T-shirt and the hot melt resin layer 25 will shift, making it impossible to transfer the design to the desired correct position. If an attempt is made to transfer them side by side onto the transfer target cloth 27 as shown in FIG. 18, the transfer mark portions 26, 26 will have uneven transfer positions on the left and right, which is not aesthetically pleasing. For this reason, there were drawbacks such as extremely poor work efficiency, such as the need to be careful to apply the pressing force from a transfer device such as an iron so that it was uniform from directly above.

This invention solves the above-mentioned problems, and allows a mark of a desired shape to be accurately and quickly transferred to a desired position, and can also be freely combined with different colors. The purpose of this invention is to obtain a heat-reversible flocked transfer fabric that is easy to use and easy to use.

<Means for Solving the Problems> In order to achieve the above object, the heat-reversible flocked transfer fabric of the present invention is provided with a temporary adhesive layer 2 on the entire surface of a heat-resistant transparent release film 1, Short fibers 3 of the same color as the temporary adhesive layer 2 formed of a material such as rayon, cotton, nylon, acrylic, polyester, etc. are densely flocked to the temporary adhesive layer 2 to form a flocked layer 4, and the flocked layer 4 is The tip portion 5 of the short fiber 3 is embedded in the entire surface of the adhesive layer 6, and an adhesive layer 6 having stronger adhesive force and elasticity than the temporary adhesive layer 2 is provided, and is also provided with numerous sharp protrusions 18, 18... The entire surface of the adhesive layer 6 is provided with a hot melt resin layer 9 on which a roughened surface portion 8 is formed.

≪Example≫ Hereinafter, a temporary adhesive layer 2 is provided on the entire surface of a heat-resistant transparent release film 1 for the heat-reversible flocked transfer fabric of the present invention, and applied to materials such as rayon, cotton, nylon, acrylic, polyester, etc. The short fibers 3 of the same color as the temporary adhesive layer 2 formed by the process are flocked to the temporary adhesive layer 2 with high density to form a flocked layer 4, and the tips 5 of the short fibers 3 are embedded in the entire surface of the flocked layer 4. At the same time, an adhesive layer 6 having stronger adhesive force and elasticity than the temporary adhesive layer 2 is provided, and in addition, numerous sharp protrusions 1 are provided.
A hot-melt resin layer 9 having a rough surface portion 8 with 8, 18, etc. is provided on the entire surface of the adhesive layer 6, and an example of its manufacturing process will be explained with reference to the drawings as follows. .

In the first step, as shown in FIG. 3, a paste-like adhesive with relatively weak adhesive strength is applied to the entire surface of a transparent release film 1 with strong heat resistance by screen printing, spraying, or other means. to form a colorless temporary adhesive layer 2.

In the second step, as shown in FIG. 4, a temporary adhesive layer 2 made of a material such as rayon, cotton, nylon, acrylic, polyester, etc. length 0.3
The flocked layer 4 is formed by flocking short fibers 3 of the same color as the temporary adhesive layer 2 at a length of about 3 mm to 3 mm in a dense and upright state using electrical or mechanical means, and is relatively bonded by heat drying or other means. The solvent of the weak glue-like adhesive is evaporated to make it adhere to a heat-resistant transparent release film 1.

In the third step, as shown in FIG. 5, the tip portions 5 of the short fibers 3 are embedded in the entire surface of the flocked layer 4, which has been flocked in a highly dense and upright manner in the second step, and has a stronger adhesive force than the temporary adhesive layer 2. and a stretchable adhesive layer 6
form.

In the fourth step, as shown in FIG. 6, the entire surface of the adhesive layer 6 formed with a paste-like adhesive having strong adhesive force and elasticity is coated in the third step before the adhesive layer 6 is pasty and does not dry. A block-shaped hot melt resin agent 7 having an angular outer surface and a sharp protrusion 18 is adhered and bonded with high density.

In the fifth step, as shown in FIG. 7, the adhesive layer 6 formed of a glue-like adhesive having strong adhesive force and elasticity formed in the third and fourth steps and the adhesive layer 6 adhered thereon. In order to fix the hot melt resin agent 7, the solvent of the pasty adhesive forming the adhesive layer 6 is heated at a low temperature that does not dissolve the hot melt resin agent 7, or is dried by other means to create a strong adhesive force. The adhesive layer 6 formed of an adhesive having the above-mentioned properties is fixed to the hot melt resin agent 7 having an angular outer surface and a pointed protrusion 18.
A hot melt resin layer 9 is formed on the entire surface of the adhesive layer 6, on which a rough surface portion 8 having numerous sharp protrusions 18, 18, . . . is formed.

Thus, a heat reversible flocked transfer fabric 10 is formed.

Further, 11 is a member to be transferred, 12 is a processed surface of the member to be transferred 11, and the transfer member pieces 13 such as designs and characters to be transferred to the member to be transferred 11 are cut by a cutter 14. However, a design pattern 16 that matches the transfer member piece 13 is formed on the back surface 15 of the release film 1, and the design pattern 16 is cut along the design pattern 16 with a cutter 14 such as scissors, a knife, or a mold. 17 is a pattern.

Further, the hot melt resin agent 7, which has an angular outer surface and a sharp protrusion 18, forms a hot melt resin layer 9 that melts under heat and pressure, penetrates into the transfer cloth, and adheres designs and characters. Those that melt at a temperature that does not impair texture or physical properties and have a remarkable adhesive effect are selected and used, such as polyciado, polyester, E, V, A, and others.

In addition, the short fibers 3 of the flocked layer 4 to be densely planted are rayon,
Cotton, nylon, acrylic, polyester, and other fibers are cut (about 0.3 mm to 3 mm in length) and colored as needed, resulting in a finish with both texture and luster.

In addition, the release mother film 1 has high transparency and does not change its physical properties at the transfer temperature during thermal transfer, and has been confirmed to be safe and hygienic due to its strong mechanical properties and chemical resistance that can withstand peeling resistance during transfer. It uses a film that has been

For example, the usable temperature for polyester film is generally said to be -70℃ to +150℃, but its melting point is 260℃ or higher, and for a short period of time it can be used at approx.
You should use one that can withstand temperatures of 200℃.

Further, when the temporary adhesive layer 2 and the release film 1 are peeled off after heat transfer, it is necessary to take measures to prevent the temporary adhesive layer 2 from separating from the release film 1 and remaining on the surface of the pattern 17. There is. That is, it is necessary to use an adhesive suitable for adhering the film surface. For example, adhesives should be devised that are mainly made of urethane, ionomer water-based resin, aromatic polyester ionomer water-based resin, etc., and whose adhesive strength is adjusted according to the purpose of use as a temporary adhesive.

That is, a compounding example for a temporary bonding adhesive: 60 parts of a solution of 2.5 to 3 parts of sodium algin dispersion per 100 parts of water 24 parts of polyester ionomer water-based resin 16 parts of acrylic water-based resin Adjust and use as adhesive for temporary adhesive layer 2.

It is also effective to roughen the film surface by sanding, blasting, or the like to form a finely roughened surface 19, and to physically increase the adhesive effect on the film surface to strengthen the adhesive force. As a result, the release film 1 and the temporary adhesive layer 2 do not separate and remain on the surface of the pattern 17 during peeling as shown in FIG. 15, and a beautiful pattern 17 can be obtained.

≪Operations and Effects of the Invention≫ The present invention has the above-described structure, and a temporary adhesive layer 2 is provided on the entire surface of a heat-resistant transparent peeling film 1, and a temporary adhesive layer 2 is provided on the entire surface of a heat-resistant transparent release film 1, and a film of rayon, cotton, nylon, acrylic,
Short fibers 3 of the same color as the temporary adhesive layer 2 formed of a material such as polyester are densely flocked to the temporary adhesive layer 2 to form a flocked layer 4, and the tips of the short fibers 3 are attached to the entire surface of the flocked layer 4. While embedding the portion 5, the temporary adhesive layer 2
An adhesive layer 6 having a stronger adhesive force is provided,
In addition, by providing the hot melt resin layer 9 on the entire surface of the adhesive layer 6, a pattern 17 such as a necessary design or character can be applied to the processed surface 12, which is a transferred member 11 such as a T-shirt or other clothing item. To form a transfer,
A transfer member piece 13 of a required design or character is placed on the back surface 15 of the peeling film 1, for example, as shown in FIGS. 8 and 9.
A design pattern 16 is written as shown in FIG.
Cut the transfer member piece 1 as shown in FIG.
3 and placed on the surface 12 to be processed so that the overall balance can be determined before adhesion.

Therefore, the overall balance, for example, as shown in FIG.
After adjusting the positional relationship between parts 3 and 13, the hot melt resin agent 7 is heated with a heating device such as an iron to a temperature at which the hot melt resin agent 7 melts.The melted hot melt resin agent 7 flows into the structure of the workpiece surface 12, and after heating, the workpiece surface 12
As the hot melt resin agent 7 cools down, the hot melt resin agent 7 that has flowed into the hot melt resin agent 7 solidifies and becomes a strong adhesive state.

In addition, numerous sharp protrusions 1 are formed on the entire surface of the adhesive layer 6.
Since the hot melt resin layer 9 is provided with the rough surface portion 8 having the rough surface portions 8, 18, etc., when the transfer member piece 13 is placed on the workpiece surface 12, it does not slip and the rough surface portion 8 is smooth. As shown in FIG. 14, the protrusions 18, 18... bite into the surface of the transfer material 11, which is a textile such as clothing such as a T-shirt, to ensure the transfer operation at a desired position. It is something to do.

Furthermore, when the surface 12 to be processed has cooled and the release film 1 is peeled off as shown in FIG. It is possible to strongly adhere and form a beautiful three-dimensional pattern, and it is also easy to transfer to a transfer target material that has elasticity, and when the transfer target material expands and contracts, short fibers 3. The gaps between the short fibers 3 are adjusted appropriately by the stretchable adhesive layer 6, and the short fibers 3 whose tips 5 are embedded in the adhesive layer 6 are prevented from falling off, making it possible to obtain three-dimensional and beautiful designs or letters. It is possible.

Furthermore, since the temporary adhesive layer 2 provided on the entire surface of the transparent release film 1 and the short fibers 3 forming the flocked layer 4 are of the same color, it is possible to transfer the color of the pattern 17 to be transferred before transfer without making a mistake. be.

That is, the present invention makes it possible to transfer a three-dimensional mark of a desired shape and color to a stretchable clothing item such as a T-shirt by matching the colors before transfer, and also to freely combine the marks. To make it possible to reliably and beautifully transfer a mark such as a design or a character that suits a user's preference to a desired position without shifting the transfer position.

Furthermore, it has a very simple structure, is suitable for mass production, can be provided at low cost, and has many industrial effects such as being able to be easily transferred by women and girls using an iron.
