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 2 as shown in Figure 17 of the figure.
A hot melt resin film 22 is adhered to one side of the sheet 1 by heat, and the desired design or character shape is cut out or punched out along the perforation lines marked on the back side in the same manner as described above, and hot-pressed onto a shirt, etc. There is a known method for bonding marks by melting hot melt resin bonded to mark fabric.

By the way, in the former method, when making a pattern or character mark, the surface of the fabric member is stained with a writing instrument, thereby losing its usefulness as a mark, and the surrounding area of the mark is sewn, regardless of its size, so it cannot be used to remove personal names, etc. The use of multiple designs and letters, such as the above, requires effort and time, and is extremely inefficient due to individual differences in sewing techniques, and also poses problems in terms of aesthetics and texture. , there is no need to sew as in the former case, and the hot-melt resin film is thermally bonded to one side of the mark fabric material, and the hot-melt resin film is melted by thermo-pressure and adhered to the shirt, etc., but the hot-melt resin melts and flows into the mark fabric material. So,
It hardens the mark fabric material, impairs its elasticity and significantly impairs its feel, and furthermore, as mentioned above for both the former and latter, marking the surface of the fabric with a writing instrument along with the cut lines contaminates the fabric. Therefore, if a mark is placed on the back side and cut, the mark must be placed 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 buried in the entire surface of the fabric member 3, and an adhesive layer 6 having stronger adhesive force and elasticity than the temporary adhesive layer 2 is provided, and the adhesive layer The entire surface of the adhesive layer 6 is provided with a hot melt resin layer 9 that is adhered to the entire surface of the adhesive layer 6 and has a roughened surface 8.

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 base fabric 1 for peeling is bonded only to the temporarily bonded surface portion 19 so as not to be buried, and the solvent of the glue-like adhesive, which has a relatively weak adhesive force, is evaporated by heat drying or other means.
However, it depends on the material of the fabric member 3 whether the surface portion 4 is bonded only to the temporary bonding surface portion 19 or whether the surface portion 4 is bonded with the surface portion 4 slightly digging into the temporary bonding surface portion 19. Time temporary adhesive layer 2
The viscosity can be adjusted depending on the degree of dryness.

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. An adhesive layer 6 having strong adhesive force is formed.

In the fourth step, as shown in FIG. 6, a spider web-like hot-melt resin film 7 is adhered to the entire surface of the adhesive layer 6 formed with a glue-like adhesive having strong adhesive force and elasticity in the third step. let

In the 5th step, as shown in FIG. In order to fix the hot melt resin film 7, the adhesive layer 6 is formed by drying the solvent of a glue-like adhesive with strong adhesive force by heating or other means, and the spider web-like hot melt resin film is formed of an adhesive with strong adhesive force. A hot-melt resin layer 9 is formed on the entire surface to which 7 is fixed and the surface 8 is roughened.

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, and 20 is a fiber.

Further, the spiderweb-like hot melt resin film 7, which melts under heat and pressure and penetrates into the transfer cloth to form the adhesive layer 9 for adhering designs and letters, melts at a temperature that does not impair the texture and physical properties of the transfer member. Those with remarkable adhesive properties are selected and used, such as polyacid, polyester, E, V, A, rosin, pinello, etc.
In addition, a material that has been processed into threads and intertwined like a spider's web and finished in a non-woven fabric is used, and the hot melt resin layer 9 prevents the hardening of the surface 8 and increases flexibility to improve transfer work. It can encourage

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 matrix 1 are peeled off after the heat transfer, the temporary adhesive layer 2 does not separate from the release matrix 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 Adjust the viscosity of the resin glue with the above composition with ammonia water to create an adhesive for temporary adhesive layer 2. Use as.

When the release material 1 is made of a film, the surface of the film to be used is roughened by sanding, blasting, etc. to form a finely rough surface 18, and the film surface is processed to physically increase the adhesion effect. Strengthening your power is also effective. As a result, the 15th
A beautiful patterned member 17 can be obtained without the peeling matrix 1 and the temporary adhesive layer 2 being separated from each other and remaining on the surface of the patterned member 17 during peeling as shown in the figure.

If 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 there is no failure. It is capable of transcription work.

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.
An adhesive layer 6 having stronger adhesive force and elasticity is provided, and a spider web-shaped hot melt resin film 7 is adhered to the entire surface of the adhesive layer 6.
By providing the hot-melt resin layer 9 with a rough surface on the entire surface of the adhesive layer 6, a pattern member 17 such as a necessary design or letter can be transferred to a transfer member 11 such as clothing such as a T-shirt or a bag. The processed surface 1 is
2, transfer member pieces 13 such as necessary designs or letters are transferred to the surface layer 1 of the base fabric 1 for peeling.
For example, a design pattern 16 is written on 5 as shown in FIGS. 8, 9, and 10, and the transfer member piece 1 is cut along this design pattern 16 with a cutter 14.
3 is formed, and the transfer member piece 13 is first placed on the surface to be processed 12 as shown in FIG. This prevents staining of the fabric member 3 and also prevents staining caused by the design pattern 16 that serves as a mark for cutting.

Therefore, the overall balance, for example A.
After adjusting the positional relationship of the B and C pattern transfer member pieces 13, 13, 13, when heated with a heating device such as an iron at a temperature at which the hot melt resin layer 9 melts, the melted hot melt resin layer 9 will melt onto the surface 12 to be processed. After flowing into the tissue and heating, the processed surface 12 is cooled, and the hot melt resin layer 9 that has flowed in is fixed and becomes in 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 form beautiful three-dimensional patterns with strong adhesion, and it is also easy to transfer to a transfer target material that has elasticity, and when the transfer target material expands and contracts, it is possible to use fabrics, felts, etc. Fibers 20 whose tip portions 5 are embedded in the adhesive layer 6 with gaps between the fibers of the sheet-like fabric member 3 formed by, for example, adjusted appropriately by the adhesive layer 6.
This prevents the paper from falling off, prevents the cut portion from fraying, and provides 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
