By making the temporary adhesive layer 2 white or colorless, the color of the pattern coloring layer 12 and the color of the temporary coloring layer 15 are the same when the short fibers 3 are colored by the coloring paint agent 11. When the base plate 1 is formed of a transparent mother film for peeling, the color of the pattern coloring layer 12 can be known from the back surface (see FIG. 11).

Reference numeral 19 denotes a member to be transferred, and 17 denotes a surface to be processed of the member to be transferred 19 (see FIGS. 9, 19, and 28). Reference numeral 18 denotes a pattern, and the pattern 18 has a pattern portion surface 23 on which the short fibers 3, 3... Are not planted and a flocking surface 24 on which the short fibers 3, 3,. (See Fig. 10).

In addition, the mother film for peeling, which is one material forming the base plate 1, has high transparency, does not cause a change in physical properties at the transfer temperature during thermal transfer, and has strong mechanical properties that can withstand the peeling resistance during transfer. It uses a film whose chemical resistance has been confirmed to be safe and healthy.

For example, the usable temperature of a polyester film is generally -70 ° C to + 150 ° C, but the melting point is 260 ° C.
C. or higher and should be able to withstand about 200.degree. C. for a short time.

Further, when the temporary adhesive layer 2 and the base plate 1 of the peeling mother film are peeled off the base plate 1 of the peeling mother film after the heat transfer, the temporary adhesive layer 2 is separated from the base plate 1 of the peeling mother film and the pattern 18 is removed. It is necessary to devise it so that it does not remain on the surface of the surface. That is, it is necessary to use a suitable adhesive suitable for bonding the film surface. For example, it is necessary to devise an adhesive mainly composed of urethane, an ionomer aqueous resin, an aromatic polyester ionomer aqueous resin, etc., and adjusting the adhesive force according to the purpose as a temporary adhesive.

As an example of a practical example Formulation example A solution of 2.5 to 3 parts of sodium alginate in 100 parts of water 60 parts Polyester ionomer aqueous resin 24 parts Acrylic aqueous resin 16 parts The viscosity of the resin paste of the above formulation is adjusted with ammonia water and temporarily bonded. Used as an adhesive for layer 2.

As two examples of implementation, the film surface is roughened by sand, blast method, etc.
It is also effective to form a fine rough surface and apply a process for physically increasing the adhesive effect to the film surface to enhance the adhesive force. As a result, a beautiful pattern 18 can be obtained without the base plate 1 and the temporary adhesive layer 2 of the peeling mother film being separated from each other at the time of peeling and remaining on the surface of the pattern 18.

The adhesive of the temporary adhesive layer 2 is a coloring paint 11 such as a pigment or a dye.
In order to form the colored temporary adhesive layer 15 which is colored in the same shape as the pattern colored layer 12 over the front and back, it is necessary to use a white or plain material without coloring.

When the hot melt agent layer 9 is heated at a temperature at which the hot melt agent layer 9 is melted by a heater such as an iron, the melted hot melt agent layer 9 flows into the structure of the processing surface 17 of the member to be transferred 19 and is heated and then processed. As the surface 17 cools, the hot melt agent layer 9 that has flowed in adheres and becomes strongly adhered.

Next, after the work surface 17 is cooled, FIGS. 9, 19, 28
When the base plate 1 is peeled off as shown in the figure, the portion of the pattern adhesive layer 7 is strongly adhered by the hot melt agent layer 9 flowing into the surface 17 to be processed, so that the three-dimensional pattern is beautiful, has a good texture and is clear. It is possible to form a pattern, it is also easy to transfer to the transferred member 19 having elasticity, and when the transferred member 19 expands and contracts, the short fibers 3, 3. The gap is appropriately adjusted by the pattern adhesive layer 7, so that the short fibers 3, 3... Burying a part of the tip 6 in the pattern adhesive layer 7 are prevented from falling off, and a three-dimensional and beautiful pattern can be obtained. Things.

The pattern adhesive layer 7 is replaced with the temporary adhesive layer 2 and the short fibers 3 of the flocking layer 4.
And a second pattern adhesive layer 7 ″ formed on the upper surface of the first pattern adhesive layer 7 ′ so that all the tips 6 of the short fibers 3 are buried. .. Are exposed from the pattern adhesive layer 7 and adhere to the fixing pattern adhesive layer 8 so that the short fibers 3 , 3 ... will not appear and become unsightly.

Further, the upper surface of the pattern adhesive layer 7 is applied to the upper surface of the pattern adhesive layer 7 between the fixing pattern adhesive layer 8 formed in a state where a part of the tip 6 of the short fiber 3 is buried. By forming the pattern layer 10 which is further peeled off and adheres to the fixing pattern adhesive layer 8, the material of the fixing pattern adhesive layer 8 does not appear on the pattern portion surface 23 during transfer formation, and the pattern layer 10 appears. By forming the pattern layer 10 appropriately from a material having a pattern, a beautiful pattern portion surface 23 can be formed.

Also, the short fibers 3 formed with the temporary adhesive layer 2 and the flocking layer 4 provided on the flocking fabric 5 are colored with a coloring paint agent 11 such as a pigment or a dye to form a required pattern coloring layer 12, thereby forming a flocking pattern. The surface 24 can be made to have desired beautiful and varied colors.

Also, by providing the pressure-sensitive adhesive layer 25 in place of the hot melt agent layer 9 on the fixing pattern adhesive layer 8, the image is transferred without using a heater such as an iron only by applying a strong pressure without using heat bonding. It can be convenient.

Further, the structure is extremely simple, it is suitable for mass production and can be provided at low cost, and can be transferred by women and girls using an iron with a simple operation.
