Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention provides a short fiber transfer sheet for forming short fiber designs on the surface of fabrics such as shirts by a transfer method.

Regarding conventional short fiber transfer sheets, so far, Japanese Patent Publications No. 4768 of 1963, No. 35619 of 1963, and No. 3511 of 1963
No. 1, No. 7413 of 1980, No. 2800 of 1980
No. 8, there are many things disclosed in the official gazette. However, Jikoko 54
Publication No. 28008 (・τExcept for those disclosed, the pattern of short fibers transferred from the bases IF and Mk of the short fiber transfer sheet cannot be seen through, so when transferring the short fiber pattern to the fabric surface of a shirt etc. 2.One method disclosed in Utility Model Publication No. 28008 of 1972 is to first apply temporary adhesive in a pattern on the board,
Short fibers are planted on this and transfer adhesive is applied in a pattern on top of the short fibers, so two plates are prepared: one to apply the temporary adhesive and one to apply the transfer adhesive. Since the transfer adhesive is further applied in a pattern on the short fibers planted in a pattern on the temporary adhesive, there is an inconvenience that positioning is time consuming.

Problems to be Solved by the Invention The present invention solves the disadvantages of the inventions and ideas disclosed in the above-mentioned publications, and uses a transparent or translucent synthetic resin film as the substrate constituting the short fiber transfer sheet. The transferred design can be seen through from the back side, making it easy to locate the transfer position, and since the above film is used as the substrate, the adhesive applied to the substrate for implanting the short fibers will transfer the short fibers. Particular consideration has been given to avoid the inconveniences described in the International Special Publication No. 4768 of 1963.

Means to solve the problem: Apply corona discharge processing to one side of a transparent or translucent thermoplastic synthetic resin film, and apply a hot-melt synthetic resin adhesive to the treated side to form an adhesive coating layer. A short fiber transfer sheet is constituted by a short fiber implanted sheet in which short fibers are implanted and dried by heating.

Function: Since the substrate is a transparent or translucent thermoplastic synthetic resin film, the pattern on the transfer sheet can be seen from the back side of the substrate, making positioning during transfer easy.

A synthetic resin film containing polyester, polypropylene, or the like as a main component is used as the embodiment substrate. This film should be transparent or translucent, and should have a heat resistance temperature of 180° C. or higher and a melting point of 200° C. or higher.

One side of this film is subjected to a corona discharge treatment to give it a satin finish, thereby imparting adhesive coating properties to the film surface.

Next, a very thin layer of a synthetic resin adhesive made of special protective colloidal polyester synthetic resin and having a melting point of 160 DEG C. or higher is applied to the treated surface of the film. Since this adhesive is of the same type as the film, the two adhere strongly.

A heat-resistant mold release agent, a penetrating agent, etc. are added to this adhesive.

Short fibers are implanted in the adhesive coating layer by the h@flocking method. Thereafter, this is dried and the short fibers are firmly planted to produce a short fiber planted sheet.

The short fibers planted on the short fiber planting sheet are colored with a design by a normal silk screen printing method.

The adhesive coating layer also contains a penetrant a'! 1. Therefore, the colored ink penetrates into this layer and colors even the roots of the implanted short fibers.

After this colored ink dries, a pattern layer made of cross-linkable synthetic resin is formed on the colored portion of the pattern layer, a powdered hot-melt adhesive is sprinkled on the layer, and then dried to form the pattern layer. By using the above film as a substrate on which the powdered hot melt adhesive is spread on the layer and fixed on the layer in a semi-molten state, the colored state of the root portion of the short fibers can also be seen from the back side of the film. You can check it.

In addition, by mixing and blending a heat-resistant stabilizer into the adhesive component of the adhesive coating layer formed to implant short fibers into the film, the film will not change in size or curl even after the drying process of political change. was able to be prevented.

In order to transfer a short fiber pattern onto a fabric such as a shirt using the short fiber transfer sheet of the present invention, the pattern layer of the short fiber transfer sheet is applied to the surface of the object to be transferred (for example, the fabric of a shirt, etc.) using the conventional method. Overlap the surfaces of the dispersed hot melt adhesive powder. At this time, since the pattern transfer position can be seen through the back surface of the film, which is the substrate, the positioning is easy.

This is heated and pressed using a heat suppression device. The heating temperature is about 150° C. and the heating time is about 20 seconds. This heat suppression melts the powdered hot melt adhesive, which penetrates into the fabric of a shirt, for example, and at the same time adheres the pattern layer formed of the crosslinked synthetic resin to the fabric surface of the shirt or the like.

Incidentally, the melting point of powder hot melt f&adhesive is 120℃~1
Since the temperature is 30° C., neither the film nor the adhesive coating layer for implanting the short fibers into the film will be melted by this heating and pressurization. However, the adhesive coating layer is softened.

After this work is completed, when the short fiber planting sheet is removed from the fabric surface of the shirt, etc., the short fibers soften together with the pattern layer, as the pattern layer is in strong contact with the fabric surface of the shirt, etc. As soon as the adhesive coating layer is easily pulled out along the pattern layer onto the fabric surface of a shirt or the like, a pattern of short fibers is transferred and formed on the fabric surface of the shirt or the like.

effect By using the above film for the substrate.

Unlike conventional platters, it has good heat conductivity and can shorten the transfer processing time, and also prevents the phenomenon that the adhesive coating layer peels off from the film during transfer, as described in Japanese Patent Publication No. 4768 of 1963. can be prevented.
