Description

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

BACKGROUND ART Conventionally, many materials have been used as mark fabrics, including felt fabric and melton fabric, but as a general rule, they are processed and used by the following two methods.

In other words, cut felt fabric, melton fabric, or other material along the cutting line marked on the back side with scissors.
Cut out or punch out the required design or letters using a knife, metal mold, etc., and sew it onto the back of the shirt, chest, arms, or other necessary places by hand or with a sewing machine, or
Or mark fabric material 6 as shown in Figure 16 in the figure.
A hot-melt resin film 20 is adhered to one side of the sheet by heat, and the desired design or character shape is cut out or punched out along the cut-off line marked on the back side in the same way as described above, and the sheet is heated and pressed onto a sheet, etc. There is known a method for bonding marks by melting a hot melt resin bonded to mark fabric.

By the way, in both the former and the latter, when making a pattern or letter-like mark, the surface of the fabric member is stained with a writing instrument and loses its usefulness as a mark, and in the former, the periphery of the mark is sewn, regardless of its size.
The use of multiple designs and letters, such as people's names, takes time and effort, and also involves individual differences in sewing techniques, making it extremely inefficient and problematic in terms of aesthetics and texture. However, in the latter case, it is not necessary to sew as in the former case, but in both the former and latter cases, as mentioned above, marking the front surface cut line with a writing instrument will contaminate the fabric, so it is better to put the mark on the back side and then cut. There were drawbacks such as the fact that the marks had to be inserted in the opposite direction, making workability extremely poor.

Technical Problem This invention solves the above-mentioned drawbacks,
The technical objective is to obtain a heat reversible transfer fabric that is easy to manufacture and convenient to use.

Technical Means In order to solve the above-mentioned technical problem, the present invention provides a temporary adhesive layer 2 on the entire surface of a heat-resistant release base fabric 1, and a sheet-like fabric member 3 made of woven fabric, felt, etc. is temporarily attached to the temporary adhesive layer 2, and the tip 5 is further buried in the entire surface of the fabric member 3, and a hot melt resin agent 7 in powder or pellet form having a stronger adhesive force than the temporary adhesive layer 2 is provided and pasted. A deposited layer 9 is formed.

Embodiment An embodiment of the manufacturing process of the thermal reversal type transfer fabric of the present invention will be described below with reference to the drawings.

In the first step, as shown in FIG.
A paste-like adhesive with relatively weak adhesive strength is applied to the entire surface of the temporary adhesive layer 2 by spraying or other means.
form.

In the second step, as shown in FIG. 4, temporary adhesive is applied to the colorless (transparent), white, or colored temporary adhesive layer formed from the relatively weak paste-like adhesive formed in the first step. Sheet-like fabric members 3 made of woven fabric, felt, etc. having a different color or the same color as the adhesive layer 2 or with an appropriate pattern are laminated, and the surface portion 4 of the sheet-like fabric member 3 is inside the temporary adhesive layer 2. The adhesive is bonded only to the temporary adhesive surface portion 19 so as not to be buried, and the solvent of the paste-like adhesive, which has a relatively weak adhesive force, is evaporated by means such as heat drying, and the adhesive is fixed to the release material 1. Whether the surface portion 4 is bonded only to the temporary bonding surface portion 19 or the surface portion 4 is bonded with the surface portion 4 slightly biting into the temporary bonding surface portion 19 depends on the material of the fabric member 3 and the drying of the temporary bonding layer 2 during bonding. The viscosity can be adjusted depending on the degree of viscosity.

If the surface portion 4 of the fabric member 3 is adhered only to the temporary adhesive surface portion 19 so as not to be buried inside the temporary adhesive layer 2, the temporary adhesive layer 2 and the fabric member 3 can be separated very easily.

In the third step, as shown in FIG. 5, powder or pellet-like powder having a stronger adhesive force than the temporary adhesive layer 2 is applied to the entire surface of the sheet-like fabric member 3 temporarily attached to the temporary adhesive layer 2 in the second step. The hot-melt resin agent 7 is adhered and adhered with high density.

In the fourth step, as shown in FIG. 6, in order to fix the fabric member 3 formed in the third step and the hot melt resin agent 7 attached thereon, the hot melt resin agent 7 is fixed by heating or other means. At the same time, the surface 8 is made rough and an adhesive layer 9 in which the tip 5 of the fabric member 3 is embedded is formed over the entire surface.

Thus, a heat reversible transfer material 10 is formed.

Note that 11 is a member to be transferred, 12 is a processed surface of the member to be transferred 11, and 12 is a processed surface of the member to be transferred 11.
The transfer member piece 13 of designs, characters, etc. to be transferred is cut with a cutter 14 such as scissors.
A design pattern 16 that matches No. 3 is applied, and the device is cut along this design pattern 16 with a cutter 14 such as scissors, a knife, or a mold. 17 is a patterned member.

In addition, the hot melt resin agent 7, which melts under heat and pressure and penetrates into the transfer cloth to form the adhesive layer 9 that adheres designs and characters, melts at a temperature that does not impair the texture and physical properties of the transfer member, and has a remarkable adhesive effect. It involves extracting and using materials, such as polyacid, polyester,
Use E, V, A series, rosin series, Pinero series, and others.

The sheet-like fabric member 3 made of woven fabric has appropriate strength, elongation, elasticity, and plasticity, and can be made of natural fabrics such as cotton fabrics, silk fabrics, human silk fabrics made of artificial fibers, staple fabrics, and other appropriate fabrics. The sheet-like fabric member 3 made of felt is also made of wool or the like, and both the woven fabric and felt are dyed as necessary to make a wide fabric.

In addition, the release base material 1 is formed of non-woven fabric, high-quality paper, film, etc., and those formed of film have high transparency and, like non-woven fabric and high-quality paper, do not change their physical properties at the transfer temperature during thermal transfer. In addition, it uses a film that has been confirmed to be safe and hygienic due to its strong mechanical properties that can withstand peeling resistance during transfer and chemical resistance.

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℃.

Furthermore, when the temporary adhesive layer 2 and the release base fabric 1 are peeled off after the heat transfer, the temporary adhesive layer 2 does not separate from the release base fabric 1 and remain on the surface of the patterned member 17. It is necessary to make some efforts. That is, it is necessary to use an adhesive suitable for bonding one side of the release material. 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.

Formulation example: A solution of 2.5 to 3 parts of sodium alginate in 100 parts of water.
60 parts polyester ionomer water-based resin 24 parts acrylic water-based resin 16 parts The viscosity of the resin glue blended above is adjusted with ammonia water and used as the adhesive for temporary adhesive layer 2.

Further, the surface of the film used as the release material 1 is roughened by sanding, blasting, etc. to form a finely roughened surface 18, and the film surface is processed to physically increase the adhesive effect to strengthen the adhesive force. is also valid. As a result, when peeling as shown in FIG. 14, the peeling matrix 1 and the temporary adhesive layer 2 do not separate and remain on the surface of the patterned member 17, making it possible to obtain a beautiful patterned member 17. be.

In addition, when the surface 8 is a rough surface, this rough surface will not slip when placed on the surface to be processed 12, and a part of the rough surface will cause the transferred member 11 to become a T-shirt or the like as shown in FIG. It digs into the surface of textiles used in clothing to ensure transfer work at desired locations.

Furthermore, if the release material 1 is made of heat-resistant synthetic resin, such as a polyester resin film, it will not be deformed by heat during the adhesion process and will be strong, and the release material 1 will be transparent. Furthermore, when the transfer member piece 13 is formed with the temporary adhesive layer 2 having the same color as the fabric member 3, the shape of the pattern member 17 to be transferred can be clearly seen through from the back side, and the pattern member 17
It is possible to sufficiently consider the orientation of the image and the clothing to be transferred before pasting, and when transferring and pasting onto the transfer target member 11, it is easy to confirm the pasting position and the transfer work can be performed without failure. It is something.

Effects This invention has the above-described configuration, in which a temporary adhesive layer 2 is provided on the entire surface of a heat-resistant release material 1, and a sheet-like fabric member 3 made of woven fabric, felt, etc. is attached to the temporary adhesive layer. 2, and further embed the tip portion 5 on the entire surface of the fabric member 3, and temporarily attach the adhesive layer 2.
By forming the adhesive layer 9 by providing a hot-melt resin agent 7 in the form of a powder or pellet having a stronger adhesive force than that of the adhesive layer 9, it is possible to apply a patterned member 17 such as a necessary design or letter to clothing such as a T-shirt. In order to transfer and form onto the processed surface 12 which is the transferred member 11 such as a product or bag, a transfer member piece 13 such as a necessary design or character is placed on the surface layer 15 of the peeling base material 1, for example, as shown in FIG. As shown in FIGS. 8 and 9, a design pattern 16 is drawn, and the transfer member piece 13 is formed by cutting along the design pattern 16 with a cutter 14. First, the transfer member piece 13 is shown in FIG. As shown, it can be placed on the workpiece surface 12 to check the overall balance before pasting, and the peeling matrix 1 prevents the fabric member 3 from being soiled and serves as a mark for cutting. This also prevents staining caused by the design pattern 16.

Therefore, the overall balance, for example A shown in the diagram,
After adjusting the positional relationship of the transfer member pieces 13, 13, 13 of the B and C patterns, when heated with a heater such as an iron at a temperature at which the adhesive layer 9 melts, the melted hot melt resin agent 7 will be applied to the processed surface 12. into the organization,
After heating, the surface 12 to be processed cools down, and the hot melt resin 7 that has flowed into the surface 12 solidifies, forming a strong adhesive state.

Next, when the surface 12 to be processed has cooled, the base material 1 for peeling is peeled off as shown in FIG. By this, it is possible to bond strongly and form a beautiful three-dimensional pattern. Furthermore, by embedding the tip 5 of the sheet-like fabric member 3 made of woven fabric, felt, etc. in the adhesive layer 9, it is possible to form a beautiful three-dimensional pattern. It is possible to prevent the paper from falling off and fraying at the cut portion, and to obtain three-dimensional and beautiful designs or letters.

Furthermore, it has an extremely simple structure, is suitable for mass production, can be provided at low cost, can be easily transferred by women and girls using an iron, and can be attached to expensive clothing with confidence. It has many industrial effects, such as the ability to
