Description

DETAILED DESCRIPTION OF THE INVENTION <<Industrial Application Field>> This invention relates to a heat-reversible flocked transfer fabric that is convenient to use and easy to manufacture, and a method for producing the same.

≪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 or punching, but as a general rule, 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 or punch out the necessary designs or letters from felt fabric, melton fabric, or other materials, and place them on the back of the shirt, chest, arms, or other necessary places by hand or with a sewing machine. A hot melt resin film is adhered to one side of the marked fabric material using heat, and then cut or punched into the desired design or character shape, and then adhered to the marked fabric by applying heat to a shirt, etc. A known method is to melt the hot melt resin and adhere the mark.

Further, as shown in FIG. 15, a temporary adhesive layer 21 is applied to the release base fabric 20 using a heat reversal type flocked transfer fabric, and short fibers 22 are densely flocked to the temporary adhesive layer 2 to form a flocked layer 23. , and a pattern adhesive layer 24 with a strong adhesive is provided on the flocked layer 23, and powder or hot melt adhesive is further sprinkled on the pattern adhesive layer 24 to form a hot melt resin layer 25.
It is known that the
(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. 15, a temporary adhesive layer 21 is applied to the release fabric 20 using a heat reversal type flocked transfer fabric, and short fibers 22 are densely flocked to the temporary adhesive layer 2 to form a flocked layer 23. In addition, a pattern adhesive 24 in the form of a pattern is provided on the top coat layer 23 using a strong adhesive, and a hot melt resin layer 25 in the form of 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. In addition, the hot melt resin layer 25 is slippery, and if a transfer device such as an iron is applied from above and pressed during transfer, the hot melt resin layer 25 is misaligned with the fabric surface of the T-shirt or the like to be adhered, making it impossible to transfer to the desired correct position. The first thing is the design
If an attempt is made to transfer them side by side onto the transfer target cloth 27 as shown in FIG. 6, the transfer marks 26, 26 will have uneven transfer positions on the left and right, which is not aesthetically pleasing.
For this reason, work efficiency is extremely poor, as the pressing force of a transfer device such as an iron must be applied from directly above so as to be uniform. Furthermore, in the case shown in Fig. 15, excess powder or pellet hot melt adhesive is removed because the powder or pellet hot melt adhesive is sprayed on flocked areas other than the required pattern during the processing process. If this was neglected, unnecessary patterns other than the design pattern would be transferred.

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 object of the present invention is to obtain a heat reversible flocked transfer fabric that is convenient to use and easy to manufacture, and a method for manufacturing the same.

The entire surface is provided with a spider web-like hot melt resin layer 9, and its manufacturing method is such that it is relatively adhesive to the entire surface of a strong release base material 1 such as high-quality paper, cloth, non-woven fabric, etc. A temporary adhesive layer 2 is formed by applying a weak glue-like adhesive. Next, short fibers 3 made of a material such as rayon, cotton, nylon, acrylic, polyester, etc. are flocked in a dense and upright state on the entire surface of the temporary adhesive layer 2 while the temporary adhesive layer 2 is pasty and does not dry. forming a flocked layer 4;
The solvent of the glue-like adhesive is evaporated to temporarily attach the temporary adhesive layer 2 to the short fibers 3, and at the same time, the temporary adhesive layer 2 and the release material 1 are fixed. Next, the tips 5 of the short fibers 3 are embedded in the entire surface of the flocked layer 4, and a glue-like adhesive having stronger adhesive force and elasticity than the temporary adhesive layer 2 is applied to form an adhesive layer 6. . Next, adhesive layer 6
A spider web-like hot melt resin film 7 is attached to the entire surface of the adhesive layer 6 while the adhesive layer 6 is pasty and has not dried, and the solvent of the paste-like adhesive is evaporated to form a spider web-like hot melt resin film 7 on the adhesive layer 6. A spider web-like hot melt resin layer 9 is formed on the entire surface of the adhesive layer 6.

<<Example>> Hereinafter, the heat reversal type flocked transfer fabric of the present invention is provided with a temporary adhesive layer 2 on the entire surface of the release base fabric 1 as shown in the drawing, and is made of rayon, cotton, nylon, acrylic,
Short fibers 3 made of a material such as polyester 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 attached to the entire surface of the flocked layer 4.
In addition, an adhesive layer 6 having a stronger adhesive force and elasticity than the temporary adhesive layer 2 is provided, and a spider web-like hot melt resin layer 9 is provided on the entire surface of the adhesive layer 6. , an example of the manufacturing method will be described below with reference to the drawings.

In the first step, as shown in FIG. 3, a paste-like adhesive with a relatively weak adhesive force is applied to the entire surface of a strong release base material 1 such as high-quality paper, cloth, nonwoven fabric, etc., using a screen printing method. The temporary adhesive layer 2 is formed by applying by spraying or other means.

In the second step, as shown in FIG. 4, short fibers made of a material such as rayon, nylon, Tetron, polyester, etc. 3 is flocked in a dense and upright state by electrical or mechanical means to form a flocked layer 4, and the solvent of the paste-like adhesive, which has a relatively weak adhesive force, is evaporated by means such as heat drying. The temporary adhesive layer 2 is temporarily attached to the short fibers 3, and the temporary adhesive layer 2 is also fixed to the release base material 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 is formed.

In the fourth step, as shown in FIG. 6, a spider web-shaped hot melt resin film 7 is adhered to the entire surface of the adhesive layer 6 formed of a pasty and adhesive having strong adhesion and elasticity in the third step. Glue.

In the fifth step, as shown in FIG. 7, an adhesive layer 6 is formed using a glue-like adhesive having strong adhesive force and elasticity formed in the third and fourth steps. Nested hot melt resin film 7
In order to fix the adhesive, the solvent of the glue-like adhesive is dried by heating or other means, and the adhesive layer 6 formed of the adhesive with strong adhesive force and elasticity is fixed to the spider web-shaped hot melt resin film 7, and the surface 8 is fixed.
A cobweb-like hot melt resin layer 9 with unevenness is formed on the entire surface of the adhesive layer 6.

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

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 applied to the back side 15 of the release base material 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.

Also, a spider web-shaped hot melt resin layer 9 that melts under heat and pressure and penetrates into the transfer cloth to adhere designs and letters.
The spider web-shaped hot melt resin film 7 that forms the transfer member is melted at a temperature that does not impair the texture and physical properties of the transfer member, and is selected from those with remarkable adhesive properties.For example, polyacid-based, polyester-based, E, V, A
It is made by processing threads and other materials into threads and intertwining them like a spider's web to create a non-woven fabric. Then,
The spider web-like hot melt resin layer 9 has its surface 8
The material prevents hardening of the material and increases its flexibility, ensuring that the entire surface of the spider web-shaped hot melt resin layer 9 is in contact with the transfer material 11, which is a transfer cloth, thereby improving the transfer work and improving workability. It is.

Also, the short fibers 3 of the dense flocked layer 4 are rayon,
Cotton, nylon, acrylic, polyester, and other fibers are cut (about 0.3 mm to 5 mm in length) and colored as needed to create a finish with both texture and luster.

The release material 1 is made of high-quality paper, nonwoven paper, cloth, etc., and is made of a strong material that does not cause aging, discoloration, or other physical property deterioration due to the temperature and pressure of heat and pressure during transfer. The adhesive of the temporary adhesive layer 2 provided on the entire surface of the base fabric 1 is weaker than the adhesive force of the strong adhesive layer 6, and the short fibers densely planted when peeling the release base fabric 1 after heat and pressure for transfer. It is an adhesive that does not remain on the surface of 3. This is because the adhesive of the strong adhesive layer 6 has good releasability of the release material 1.
It is used by mixing parapine and other substances to adjust the adhesive strength.

≪Operations and Effects of the Invention≫ This invention has the above-described structure, and a temporary adhesive layer 2 is provided on the entire surface of the release base material 1, and rayon, rayon,
Short fibers 3 made of materials such as cotton, nylon, acrylic, polyester, etc. 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. 5 is buried, and an adhesive layer 6 having a stronger adhesive force than the temporary adhesive layer 2 is provided, and a spider web-like hot melt resin layer 9 formed of a spider web-like hot melt resin film 7 is attached to the adhesive layer 6. By providing the spider web-like hot melt resin layer 9 on the entire surface thereof, the surface 8 of the spider web-like hot melt resin layer 9 is prevented from hardening and the flexibility is increased, so that the spider web-like hot melt resin layer can be applied to the transferred member 11 which is a transfer cloth. 9. This ensures the contact of the entire surface so that the transfer position does not shift and improves work efficiency. In addition, in order to transfer and form a pattern 17 such as a required design or text onto a processed surface 12 which is a transfer member 11 of clothing such as a T-shirt, a transfer member piece 13 containing the required design or text is used.
A design pattern 16 is written on the peeling base material 1 and the back surface 15, for example, as shown in FIG. First, the hot melt resin layer 9 of the transfer member piece 13 is formed as shown in FIG.
As shown in FIGS. 11 and 12, the transferred member 11
is brought into contact with the processed surface 12 of.

Therefore, when heated with a heater such as an iron to a temperature at which the hot melt resin layer 9 melts, the melted hot melt resin layer 9 flows into the structure of the processed surface 12, and as the processed surface 12 cools after heating, the melted hot melt resin layer 9 flows into the structure of the processed surface 12. The hot melt resin layer 9 is fixed and becomes a strong adhesive state.

Next, when the surface to be processed 12 has cooled down, the base material for peeling 1 is peeled off as shown in FIG. By doing so, it is possible to form a beautiful three-dimensional pattern with strong adhesion, and it is also easy to transfer to a material to be transferred that has elasticity, and it is possible to easily transfer the material to a material to be transferred that has elasticity. The gap between the fibers 3 is appropriately adjusted by the adhesive layer 6, and the short fibers 3 whose tips 5 are embedded in the adhesive layer 6 are prevented from falling off, thereby obtaining a three-dimensional and beautiful pattern 17 such as a design or letter. It is something that can be done.

In addition, conventionally, during the processing process, excess powder or pellet hot melt adhesive must be removed and cleaned because the powder or pellet hot melt adhesive is spread over flocked areas other than the required pattern. However, the spider web-like hot melt resin film 7 is adhered to the adhesive layer 6, and when forming the spider web-like hot melt resin layer 9, there is no need to perform complicated means as in the conventional process, making it a simple process. A nest-like hot melt resin layer 9 is formed. In addition, the spider web shaped hot melt resin film 7 can allow air to escape when it is bonded to the adhesive layer 6, so that residual air will not cause poor adhesion of the spider web shaped hot melt resin film 7 to the adhesive layer 6. . Further, the spider web-shaped hot melt resin layer 9 maintains its air permeability even after being adhered to the transfer target member 11, has flexibility, and maintains the texture of the pattern 17 well.

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.
