Description

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

BACKGROUND OF THE INVENTION Conventionally, many materials have been used as mark fabrics, including felt fabric and melton fabric, but in principle they are processed and used by the following two methods.

That is, use scissors, a knife, a mold, etc., to cut out or punch out the desired design or letters along the cutting lines marked on the back of the felt fabric, melton fabric, or other material, and then cut or punch out the desired design or letters on the back of the shirt or the like. A hot melt resin film 22 can be sewn onto the chest, arms, etc. by hand or with a sewing machine, or as shown in FIG. 17, on one side of the mark fabric material 21.
1m +: Same as above, cut out or punch out the required design or letter shape along the cutout line indicated on the back side, and mark the fabric by applying heat to a shirt, etc. Means for adhering marks to hot melt resin layers are known.

By the way, in the former case, when making a mold of a mark in the form of a design or a letter, the surface of the fabric member is stained with a writing instrument, thereby losing its usefulness as a mark, and since it is used to sew around the mark, regardless of its size, it cannot be used to remove the person's name. The use of multiple designs and letters, such as the
There is also a problem with the texture, and in the latter case, there is no need to sew it like in the former case, but it is thermally bonded to one side of the marking material.
Hot-melt resin film is melted by heat and pressure and adhered to shirts, etc., but since the hot-melt resin melts and flows into the mark fabric material, it hardens the mark fabric material, making it less elastic and less textured. In addition, as mentioned above for both the former and the latter, if you use a writing instrument to mark the fabric on the front side, it will contaminate the fabric, so if you cut with a mark on the back side, you can reverse the mark. However, there were disadvantages such as extremely poor workability.

TECHNICAL PROBLEM The present invention has solved the above-mentioned drawbacks, and its technical problem is to obtain a thermal reversal transfer knitted fabric that is easy to manufacture and convenient to use.

Technical Means In order to solve the above technical problem, the present invention provides a temporary adhesive Wi2 on the entire surface of a heat-resistant release base material 1,
A sheet-like fabric member 3 made of offal, felt, etc. is temporarily bonded (temporarily bonded)<42, and the tip portion 5 is buried in the entire surface of the fabric member 3, and the adhesive force and elasticity are stronger than that of the temporary bond WI2. Adhesive WI6 is provided, and also!
A hot melt resin layer 9 which is adhered to the entire surface of the RC adhesive layer 6 and whose surface 8 is roughened is provided on the entire surface of the adhesive layer 6.

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. 3, a paste-like adhesive with relatively weak adhesive force is applied to the entire surface of the release base material 1 by spraying or other means to temporarily bond; 17 layers 2 are formed. .

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 textiles, felt, etc. that are different in color or the same color as the adhesive layer 2, or have an appropriate pattern are laminated, and the surface portion 4 of the sheet-like fabric members 3 is temporarily bonded Wj2.
Adhere only to the temporary adhesion surface part 19 so as not to be buried inside, and evaporate the solvent of the paste-like adhesive, which has a relatively weak adhesive force, by heat drying or other means! ! qglt, 1u fabric 1
The surface portion 4 is the temporary adhesive surface portion 1.
Whether to bond only with 9 or with the surface portion 4 slightly biting in from the temporary bonding surface portion 19 is adjusted depending on the material of the fabric member 3 and the viscosity of the temporary bonding layer 2 at the time of bonding. It is possible.

If the surface portion 4 of the fabric member 3 is bonded only to the temporary bonding surface portion 19 so as not to be buried inside the temporary bonding hole G2, separation of the temporary adhesive layer 2 and the fabric member 3 is extremely easy.

In the third step, as shown in FIG. 5, the tip 5 of the fabric member 3 is immediately installed on the entire surface of the sheet-like fabric member 3 that has been temporarily attached to the temporary adhesive layer 2 in the fjS2 process, and temporary adhesion is performed)r! An adhesive layer 6 having a stronger adhesive force than J2 is formed.

In the fourth step, as shown in FIG. and glue.

In the fifth step, as shown in FIG. In order to fix the hot melt resin film 7, adhesive JVi6 is formed using an adhesive having strong adhesive force by heating the solvent of a glue-like adhesive having strong adhesive force and drying it by means of a hot water bath.
Hot melt resin Jr. which fixes the spider web-like hot melt resin film 7 and makes the surface 8 the real surface 11! Form I9 on the entire surface.

Thus, a thermal reversal type transfer fabric 10 is formed.

In addition, 11 is a member to be transferred, and 12 is a member to be transferred 11.
The transfer member piece 13 of the pattern, character, etc. to be transferred to the transfer member 11 is cut with a cutter 14 such as scissors.
A design pattern 16 that matches the transfer member piece 13 is applied to 5,
Cutting is performed along this design pattern 16 using a cutter 14 such as scissors, a knife, or a mold. 17 is a patterned member, and 20 is a WLR.

In addition, a honeycomb hot melt tJ(
The IITt film 7 is melted at a temperature that does not impair the texture and physical properties of the transfer member, and those with excellent adhesive properties are selected and used, such as polyacid, polyester, E, V, A, etc. We use rosin-based, vinello-based, and other thread-like materials that are intertwined like a spider's web and finished in a non-woven fabric.
Hot melt resin W! 9 prevents hardening of the surface 8 and increases flexibility to improve transfer work, which can improve workability.

In addition, the sheet-like fabric member 3 made of offal has moderate strength,
A cotton fabric made of natural materials that has elongation, elasticity, and plasticity.
The sheet-like fabric member 3 is made of silk fabric, artificial i-fiber made of artificial i-fiber, staple fabric, or other appropriate fabric, and the sheet-like fabric member 3 made of felt is also made of wool or the like, and both the fabric and felt can be used as needed. It is dyed and made into wide cloth.

In addition, the base fabric 1 for release is made of non-woven fabric, high-quality paper, film, etc. Those made of film have high transparency, and like non-woven fabric and high-quality paper, physical properties change at the transfer temperature during thermal transfer. In addition, the film 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°C to +150°C, but its melting point is 260°C or higher, and for short periods it can be used at about 200°C.
A material that can sufficiently withstand C should be used.

In addition, when the temporary adhesive layer 2 and the release material 1 are peeled off after heat transfer, the temporary adhesive layer 2 may be separated from the release material 1 and remain on the surface of the FA pattern member 17. We need to devise ways to avoid this. That is, it is necessary to use a suitable adhesive for adhering one side of the release material. For example, urethane, ionomer water-based (31 fat, aromatic ester ion/mer water-based + fl + fat, etc.) should be used as a civil engineering adhesive, and an adhesive with adjusted adhesive strength according to the purpose as temporary adhesive X1 agent should be devised. .

Formulation example 2.5 to 3 parts of sodium alginate dissolved 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 film of the above composition was adjusted with ammonia water, and the temporary adhesive layer 2 Used as an adhesive.

When the release material 1 is formed of a film, the surface of the film to be used is roughened by sanding, blasting, etc. to form a finely roughened surface 18, and the film surface is processed to physically increase the adhesion effect. Strengthening your power is also effective. This prevents the No. 1 peeling fabric 1 and temporary adhesive WI2 from separating and remaining on the surface of the patterned member 17 during peeling as shown in FIG. It is something that can be done.

In addition, when the surface 8 is a rough surface, when the surface 11 of the book is placed on the surface 12 to be processed, it will not slip and a part of the rough surface will cover the material 11 to be transferred as shown in FIG. It bites into the surface of textiles such as T-shirts and other clothing to ensure transfer at the desired position.

If the release material 1 is made of an i4 heat-resistant synthetic resin, such as a polyester resin film, it will not be deformed by heat during adhesion and will be strong, and the release material 1 will be transparent. 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 from the back side, and the direction of the pattern member 17 and the clothing to be transferred is not correct. The orientation can be thoroughly considered before pasting, and when transferring and pasting onto the transfer target member 11, it is easy to recognize the pasting position and the transfer work can be performed without failure.

Effects of this invention as above? +? ↓ A temporary adhesive layer 2 is provided on the entire surface of the fabric 1, and a sheet-like fabric member (made of fabric, felt, etc.) is temporarily attached to the temporary 7f scraps 2. In addition, a light edge 5 is buried in the entire surface of the fabric member 3, and a contact layer 6 having stronger adhesive force and elasticity than the temporary adhesive layer 2 is provided, and the entire surface of the adhesive layer 6 is A spider-like hot melt resin film 7 is adhered and the surface 8 is roughened by providing the hot melt 3 (with a fat layer 9 adhered) on the entire surface of the I'l 6, thereby making it possible to create necessary designs, letters, etc. P) In order to transfer and form the pattern member 17 on the processing surface 12 which is the transfer member 11 such as clothing such as a T-shirt or bag, the transfer member piece 13 of the required design or character is peeled off. A design pattern 16 is written on the surface layer 15 of the base fabric 1, as shown in FIG. 8, fJS9, and FIG. First, the transfer member piece 13 is placed on the surface to be processed 12 as shown in FIG.

Therefore, after adjusting the overall balance, for example, the positional relationship of the transfer member pieces 13, 13.13 of the A-B/C pattern shown in the figure, if the hot-melt resin layer is heated with a heating device such as an iron at a temperature that melts the hot-melt resin layer. Melted hot melt resin layer 9

is fixed and becomes in a strong contact 71 state.

Next, when the surface to be processed 12 has cooled down, as shown in FIG. By flowing into the workpiece surface 12, it is possible to strongly adhere and form a beautiful three-dimensional pattern, and it is also easy to transfer to the workpiece 1f member that has elasticity. ,
When the transferred member expands and contracts, the fibers M# of the sheet-like fabric member 3 formed of woven fabric, felt, etc., and the gaps between them are bonded)
It is possible to prevent the tip part 5 of the finely wired 20 from falling off, and also to prevent the cut part from fraying, as well as to create three-dimensional and beautiful designs or letters. 1- It is something that can be done.

Furthermore, the structure is extremely simple, suitable for mass production, and can be provided at low cost. Women and girls can easily transfer the image using an iron, and it is also possible to apply the stickers to expensive clothing at a low cost. It has many industrial effects, such as being able to be carried out with care.
