Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for applying visual designs, such as motifs, to textile bodies.

Visual designs of this type include trademarks, trade names, words, or other symbols, some of which may or may not indicate the origin of the textile to which they are affixed.

However, in any case, the general method of attaching a design (motif) to a textile body (hereinafter also referred to as the base body), such as an item such as a sports shirt, is to mold the design. A known method is to attach heat-welding adhesive to the back side and apply heat to it. However, such methods have drawbacks such as requiring special equipment to handle the patterned material or limiting the types of designs that can be applied.

On the other hand, British Patent Specification No. 1244407 discloses that a decorative layer is adhered onto a substrate with an intermediate layer made of elastic compressible pads in between, and then the decorative layer is molded along a desired contour line. It has been proposed to cut and press the pad to adhere the inner portion of the contour to the substrate.

The present invention has been made in consideration of the above points, and provides an improved method for attaching visual designs to textiles.

First, to describe the characteristics of this invention, in the method according to the invention, first, a woven fabric and a laminate are combined, and the laminate includes at least one decorative layer and a heat-welding adhesive attached thereto. and then applying heat to said combination through a mold corresponding to the desired motif, thereby activating at least a portion of said hot-seal adhesive layer surrounding the motif, in which said decorative layer is applied. Once the layers have adhered to the woven body, the mold is removed and the sheet-like article (laminate)
It is characterized in that only the motif portion defined by the mold is left on the textile body by peeling most of it off from the textile body.

The decorative layer can be a flocked layer, in which case the flocked layer is glued onto a backing layer which is provided with the heat-sealable adhesive layer on its opposite side. Further, the flocked layer may be held by a film-like adhesive layer, and as the film-like adhesive layer, the material constituting the heat-welding adhesive layer may be used, or Additional layers may also be used.

A further characteristic feature of this invention is the mold, which has a protruding mold part that defines the motif to be attached to the substrate, and has a welding area in that part, and a protruding part that defines the motif to be attached to the substrate, and A surface of the protruding mold part, adjacent to the area where the material forming the motif is to be pasted on the substrate, arranged at an acute angle to the surface of the welding area, and parallel to the axis of the mold. and a surface of the protruding mold portion that is close to a region where the motif material is not pasted on the substrate and is substantially parallel to the axis of the mold. In this case, the inclined surface of the protruding mold portion is preferably set at an angle of 30 to 60°, preferably 45°, to the line of the mold. The protruding mold portions (or mold shapes) can also be manufactured by cutting the mold block or by other suitable methods. In addition, in such molds, the part of the mold where the material forming the motif is not attached to the base is usually recessed more than the part of the mold where the material forming the motif is attached to the base.
A layer of material with low thermal conductivity is provided in the recessed portion.

Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

As shown in Figure 1, the mold used in this invention is
A motif is carved into a block made of a thermally conductive material such as copper, brass, or steel. However, in order to make the invention easier to understand, the motif is a circular depression, and the depth of the engraving of the mold is exaggerated.

The mold has a base 10 which is engraved with a circular inner contour 11 and a circular outer contour 12 with a larger diameter than the inner contour 11.
is being formed. The mold here is to obtain a circular motif as shown in Figure 2.
The end walls 18 adjacent to the portion to be attached to the base are arranged at an acute angle. A heating area 14 is provided at both ends of such a mold shape, and the heating area 14 is located close to the side surface of the heating (and therefore welding) area, that is, the area where the material forming the motif is not attached to the base body side. At this point, walls 15 are arranged approximately parallel to the axis of the mold.

When attaching a motif to a substrate by the method of the present invention, the substrate 16 is provided with a sheet-like motif-forming material (not shown). The material for forming this motif consists of an upper layer of flocking and a lower layer of heat-welding adhesive, which will be described in more detail later. Next, the above-mentioned mold is pressed onto the laminate and heat is applied to the mold, so that the heat-welding adhesive layer in the area 17 is adhered to the base 16. When this attachment is completed, the mold is removed and the sheet-shaped motif forming material is peeled off from the base 16. At this time, the motif 18 remains firmly attached to the substrate 16. In this example, the outer part will be peeled off from area 19 and the inner disc-shaped one will be peeled off from area 20.

By the way, as shown in FIG. 3, the motif-forming material left on the base 16 is in a raised state without using a compressible pad with elasticity as in the prior art. In this case, the backing layer of motif-forming material is designated by 21 and the flocked portion is designated by 22.

Another embodiment of the mold is shown in FIG.
The mold therein is also almost the same as that in FIG. 1 above. The difference is that in the central part of the mold, that is, the part where the motif-forming material does not adhere to the substrate,
The only difference is that it includes a material layer 24 with low thermal conductivity.

Although an example using a heating mold has been described above, high-frequency heating can also be applied to heating the mold.

Regarding the material for forming the motif, the upper layer is a flocked material and the lower layer is a heat-welded adhesive.The heat-welded adhesive has sufficient adhesive strength to handle and support the upper flocked layer. It can be in the form of a film, or the upper flocking layer can be applied onto a film of adhesive and then the film of adhesive can be covered with a heat-sealing adhesive. You can also do it. Furthermore, it is also possible to use a backing layer and provide a flocking layer on one side of the backing layer and an adhesive layer on the other side.

However, in any case, according to the pasting method of the present invention, since the pasted motif has an embossed pattern, it is possible to give an impression similar to that of embroidery on the base material, and also to create a molded pattern. Since there is no need to manufacture motifs (motifs) and motifs can be attached anywhere from a sheet of motif-forming material, it is extremely easy to use, and furthermore, motifs that are intermittent and separated from each other can be obtained. Therefore, it has excellent effects such as being widely applicable to various motifs.
