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 8 as shown in Figure 14 in the figure.
Apply hot melt resin adhesive 15 to one side of the paper using heat, and then cut out the desired design or letter shape along the cutting line marked on the back side in the same way as above, or
There is a known method for adhering the mark to a shirt or the like by applying heat and pressure to melt the hot melt resin adhered to the 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, for the latter, it is not necessary to sew as in the former, but as mentioned above for both the former and the latter, marking the front side with a writing instrument to mark the cutting line will contaminate the fabric, so it is better to mark the back side before cutting. However, there were drawbacks such as the fact that the marks had to be inserted in the opposite direction, resulting in extremely poor workability.

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 furthermore, the tip portion 5 is embedded in the entire surface of the fabric member 3, and the entire surface is provided with a film-like hot melt resin layer 9 having a stronger adhesive force than the temporary adhesive layer 2. It is.

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. 3, a temporary adhesive layer 2 Sheet-like fabric members 3 made of fabrics, felts, etc., which are different in color from or the same color as the above, or have an appropriate pattern are laminated to prevent the surface portion 4 of the sheet-like fabric members 3 from being buried inside the temporary adhesive layer 2. The temporary adhesion surface portion 18 is bonded only to the surface portion 18, 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 surface portion 4 is fixed to the release material 1. is bonded only to the temporary bonding surface portion 18, or the surface portion 4 is bonded to the temporary bonding surface portion 18 only.
Whether or not the material should be adhered in a more or less indented state can be adjusted by the material of the fabric member 3 and the viscosity of the temporary adhesive layer 2 depending on the degree of dryness at the time of adhesion. If the surface portion 4 of the fabric member 3 is adhered only to the temporary adhesive surface portion 18 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. 4, a hot melt resin film 7 is placed on the entire surface of the fabric member 3 temporarily attached to the temporary adhesive layer 2 in the second step.

In the fourth step, as shown in FIG. 5, a hot melt resin film 7 having a stronger adhesive force than the temporary adhesive layer 2 formed in the second step is embedded and fixed in the tip 5 of the fabric member 3 using strong heating. A film-like hot melt resin layer 9 having strong adhesive force is formed on the entire surface of the fabric member 3 by other means.

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 pieces 13 of designs, characters, etc. to be transferred to the surface are cut with a cutter 14 such as scissors.
A design pattern 16 that matches the design pattern 16 is applied, and the material is cut along the design pattern 16 with a cutter 14 such as scissors, a knife, or a mold. 17 is a patterned member.

The film-like hot-melt resin layer 9, which melts under heat and pressure and penetrates into the transfer cloth to adhere designs and letters, melts at a temperature that does not impair the texture or physical properties of the transfer member.
The adhesive with remarkable adhesive action is selected and used.
For example, polyacid, polyester, E, V,
Use A type, rosin type, Pinero type, 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 material 1 is made of non-woven fabric, high-quality paper, film, etc., and those made of film have high transparency and do not change their physical properties at the transfer temperature during thermal transfer, like non-woven fabrics and high-quality paper. 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 its chemical resistance.

For example, the processing temperature used for polyester film is generally said to be -70℃ to +150℃, but the melting point is 260℃ or higher, and for short periods of time, it is said that
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 surface of the release material. For example, an adhesive should be devised that is 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.

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 temporary adhesive layer 2 is made transparent, the patterned 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 providing a film-like hot-melt resin layer 9 with a stronger adhesive strength than the previous one on the entire surface of the fabric member 3, the pattern member 17 such as a necessary design or letter can be applied to clothing such as T-shirts, bags, etc. In order to transfer and form on the processed surface 12 which is the transferred member 11 such as
6 and 7 on the surface 6 of the base material 1 for peeling.
As shown in FIG. 8, a design pattern 16 is written, and the transfer member piece 13 is formed by cutting along the design pattern 16 with the cutter 14. First, the transfer member piece 13 is made as shown in FIG. The design pattern can be placed on the work surface 12 to check the overall balance before pasting, and also prevents the fabric member 3 from being soiled by the peeling base fabric 1 and serves as a mark for cutting. This also prevents contamination caused by No. 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 film-like hot-melt resin layer 9 melts, the melted film-like hot-melt resin layer 9 is covered. The hot melt resin flows into the structure of the processed surface 12, and as the processed surface 12 cools after being heated, the inflowing hot melt resin solidifies and becomes a strong adhesive state.

Next, when the surface 12 to be processed has cooled, when the base material 1 for peeling is peeled off as shown in FIG. 12 from the state shown in FIG. By flowing into the surface 12, it is possible to strongly adhere and form a beautiful three-dimensional pattern.Furthermore, the tip 5 of the sheet-like fabric member 3 made of woven fabric, felt, etc. is coated with a film-like hot melt resin layer. 9, it is prevented from falling off, the cut portion is also prevented from fraying, and three-dimensional and beautiful designs, letters, etc. can be obtained.

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 .
