This relates to a heat reversible flocked transfer fabric in which an adhesive 7 is provided to form an adhesive layer 14 and a surface 8 is roughened, and is an embodiment of the manufacturing process of the heat reversible flocked transfer fabric of this invention. The following is an explanation with reference to the drawings.

In the first step, as shown in Figure 2, it is made of heat-resistant synthetic resin and is transparent, with a finely roughened surface on the entire surface.
A white, paste-like adhesive with relatively weak adhesive strength is applied to the entire surface or necessary parts of the strong release material 1 designated as 7 by screen printing, spraying, or other means to form a temporary adhesive layer 2. do.

In the second step, as shown in Fig. 3, the relatively weak white paste-like adhesive formed in the first step is used, and the white temporary adhesive layer 2 is formed with a material such as rayon, nylon, Tetron, polyester, etc. length
The flocked layer 4 is formed by flocking short fibers 3 of about 0.3 mm to 3 mm in a high-density, upright state by electrical or mechanical means, and then is made into a glue-like layer with relatively weak adhesive force by means such as heat drying. The solvent of the adhesive is evaporated to make it adhere to the release material 1.

In the third step, as shown in FIGS. 4, 5, and 6, pigments, dyes, etc. In the colored body 12, the short fibers 3 were colored to form the pattern colored layer 9 with the required pattern or letter shape, and the white temporary adhesive layer 2 was also colored in the same color and shape as the pattern colored layer 9 on the front and back sides. It is possible to obtain a pattern colored layer 9 made of colored short fibers 13 flocked to a colored temporary adhesive layer 16, and by making the temporary adhesive layer 2 white, the colored body 12 can be obtained.
Therefore, when the short fibers 3 are also white, the colors of the pattern colored layer 9 and the colored temporary adhesive layer 16 appear the same, and the pattern colored layer 9 can be seen from the back side of the release material 1.
You can know the colors of

In addition, in the fourth step, as shown in FIG.
A glue-like adhesive having stronger adhesive force and elasticity than the temporary adhesive layer 2, such as vinyl acetate type, acrylic type, The tips 5 of colored short fibers 13 are made of latex etc.
The pattern adhesive layer 6 is formed in such a state that the pattern adhesive layer 6 is buried.

In the fifth step, a hot melt agent of hot melt resin particles or powder is applied to the pattern adhesive layer 6 formed of a glue-like adhesive with strong adhesive strength and elasticity, which is layered on the necessary designs or letters, etc. in the fourth step. 15
At the same time, in the fifth step, as shown in FIG. In order to fix the hot melt agent 15 that has been sprayed on the hot melt agent 15, the solvent of the glue-like adhesive having a strong adhesive force is dried by heating or other means, and the adhesive having a strong adhesive force and the hot melt agent 15 are fixed. The hot melt agent 15 in the form of hot melt resin particles or powder adhering to areas other than the patterned adhesive layer 6 is removed by means such as brushing. In the sixth step, as shown in FIG. 8, after removing the hot melt agent 15 that has adhered to the parts other than the pattern adhesive layer 6 in the fifth step, a necessary heating (baking process or curing process) process is carried out, and a strong The adhesive force of the pattern adhesive layer 6, which is an adhesive having a strong adhesive force, becomes strong, and the hot melt agent 15 becomes semi-dissolved and adheres to the pattern adhesive layer 6, forming a hot melt adhesive 7 and making the surface 8 a rough surface. This results in a finished state as a transfer transfer member piece 18, which is a product that allows the lines and dots constituting the pattern to be clearly and vividly thermally transferred.

Further, to explain other embodiments, Fig. 13 and Fig. 1
As shown in Figure 4, a hot melt adhesive 15 is mixed in advance into the patterned adhesive layer 6, which is a strong adhesive, in the fourth step of the above embodiment, and the hot melt adhesive is applied by a screen method, spray method, or other means. forming a pattern adhesive layer 6 provided with 7;
The fifth step by performing heat treatment etc.
This made the sixth step unnecessary.

Note that 21 is a member to be transferred, and 20 is a surface to be processed of the member 21 to be transferred.

In addition, the transparent base fabric 1 for peeling made of synthetic resin is heat resistant and has a finely roughened surface 17 on the entire surface, so that the bonding area between the temporary adhesive layer 2 and the base fabric 1 for peeling is wide, and furthermore, The adhesive layer 2 bites into the finely roughened surface 17 and firmly adheres to the two, and when peeled off as shown in FIG. It is possible to obtain a beautiful pattern 19 without any blemishes.

This invention has the above-mentioned structure, and a temporary adhesive layer 2 is provided on the entire surface of a heat-resistant release material 1, and short fibers 3 made of materials such as rayon, nylon, polyester, Tetron, etc. are temporarily adhered. A flocked layer 4 is formed by temporarily attaching densely flocked fibers to the layer 2, and the short fibers 3 of the flocked layer 4 are colored with a colored material 12 such as a pigment dye to form a pattern colored layer 9 made of colored short fibers 13. , colored short fibers 13 located in the pattern colored layer 9
A patterned adhesive layer 6 embedding the tip 5 of the temporary adhesive layer 2 and having stronger adhesive force and elasticity than the temporary adhesive layer 2.
By providing a hot melt adhesive 7 on the pattern adhesive layer 6 to form the adhesive layer 14, the pattern 19 corresponding to the pattern dyeing layer 9 can be transferred to clothing items such as T-shirts, bags, etc. In order to perform transfer formation on the processed surface 20 of the member 21, the adhesive layer 14 of the transfer member piece 18 provided with the required pattern dyed layer 9 is brought into close contact with the processed surface 20.

By the way, since the surface 8 of the adhesive layer 14 is made rough, this rough surface does not slip when placed on the surface 20 to be processed, and a portion of the rough surface covers the transfer member 21 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, and when heated with a heating device such as an iron at a temperature that melts the hot melt adhesive 7, the hot melt adhesive 7 melts. The adhesive 7 flows into the structure of the surface to be processed 20, and as the surface to be processed 20 cools after being heated, the hot melt adhesive 7 that has flowed in is fixed and becomes a strong adhesive state.

Next, when the surface 20 to be processed has cooled, when the base fabric 1 for peeling is peeled off as shown in FIG.
By flowing into the processed surface 20, it is possible to strongly adhere and form a beautiful three-dimensional pattern, and furthermore, it is easy to transfer to a material to be transferred that has elasticity. When the transferred member expands and contracts, the distance between the colored short fibers 13 is adjusted appropriately by the pattern adhesive layer 6, and the colored short fibers 13 whose tips 5 are embedded in the pattern adhesive layer 6 are prevented from falling off. It is possible to obtain beautiful patterns.

Furthermore, it has an extremely simple structure, is suitable for mass production, can be provided at low cost, and can be easily transferred by women and girls using an iron.

Moreover, since the release material 1 is made of heat-resistant synthetic resin, it is strong and will not be deformed by heat during the adhesion process, and the release material 1 is transparent, and it also has a colored temporary adhesive layer. 16 is colored in the same shape as the patterned colored layer 9 made of colored short fibers 13 over the front and back sides of the temporary adhesive layer 4, so the colored temporary adhesive layer 16 can be clearly seen through from the back side, and the patterned colored layer 9 and the clothing are transferred. It is easy to handle because it is possible to fully consider the orientation of the product before pasting, and when pasting onto the transferred member 21, it is easy to confirm the pasting position and the transcription work can be performed without failure. At the same time, it has many practical effects such as being able to be attached to expensive clothing with peace of mind.
