Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to cut foil and cut foil material having the ability to weave decorations or patterns, particularly three-dimensional decorations or patterns.

Conventional technology and its problems Conventionally, cut foil that creates three-dimensional decorations or patterns has been made by applying adhesive in a pattern to the surface of a base sheet, then adding color or metallic luster to it, or applying gold or silver foil to it. Cut foil obtained by slitting the original cut foil obtained by stacking the sheets, cut foil obtained by slitting the original cut foil with a three-dimensional pattern on the surface of the base sheet, and cut foil obtained by slitting the original cut foil obtained by stacking the sheets, cutting foil obtained by slitting the original cut foil obtained by stacking the sheets, cutting foil obtained by slitting the original cut foil obtained by stacking the sheets, cutting foil obtained by slitting the original cut foil obtained by slitting the original cut foil obtained by stacking the sheets. Cut foil obtained by slitting paper, synthetic resin, etc. attached in a pattern to make it three-dimensional by pushing it up from the back, and cut foil obtained by slitting paper or synthetic resin that is pressed up from the back to make it three-dimensional. The resulting cut foil is known. However, since these cut foils have three-dimensional patterned parts on the original cut foil, the following problems arose.

There are two types of pattern-woven Kirihaku: Hikihaku, which is weft inserted according to the so-called Junbiki technique, and so-called warp leaf, which is used for warps. It is obtained by stacking several sheets of raw material and cutting it with a guillotine cutter, and the latter is obtained by cutting a long warp foil material using a slitter with many parallel roll blades called a micro slitter.
In the case of Hikihaku, if the degree of unevenness due to the three-dimensional pattern is large, cutting cannot be done unless the number of stacked Hikihaku rolls is reduced, resulting in poor workability. arise.
In the case of warp foil, if the degree of unevenness due to the three-dimensional pattern is large, the blade of the micro slitter will wear out quickly when cutting the raw warp foil, so it is necessary to reduce the degree of unevenness of the three-dimensional pattern. A three-dimensional pattern with a small degree of unevenness has low decorative value. In addition, with warp foil, when winding slit cut foil on a bobbin, the three-dimensional patterned convex portions got caught in the thread path, making it extremely difficult to do so.

In addition, conventional three-dimensional patterned cut foils were quite difficult to weave because the three-dimensional patterned protrusions got caught in shuttles, reeds, and other thin thread paths during weaving.

Furthermore, in conventional cut foil with a three-dimensional pattern, the adhesive or resin used as a means for imparting three-dimensionality is on the outer surface, the front or back surface, so if the means is changed to foamed resin in order to improve the texture, the cut foil can be It cannot withstand the friction that occurs when the original fabric is slit or the cut foil is woven into the fabric, and the three-dimensional pattern is easily damaged. Even if it were possible to make slits or weave, the three-dimensional pattern would be damaged by the pull and friction that occurs when the fabric is used. In any case, it is far from practical in terms of quality.

An object of the present invention is to provide a cut foil and a cut foil material having the ability to weave three-dimensional decorations or patterns, which eliminates the problems caused by the above-mentioned conventional techniques.

Means for Solving the Problems The above object of the present invention is achieved by a cut foil and a cut foil original fabric having the following configuration.

A cut foil characterized in that the front, back, or at least the surface of a laminate of two or more base sheets in which a heat-foamable resin is interposed in an arbitrary pattern in an intermediate layer is decorated, and the laminate is slit.

1. A cut foil material comprising a laminate of two or more base sheets in which heat-foamable resin is interposed in an arbitrary pattern in an intermediate layer, and the front, back, or at least the surface of the laminate is decorated.

In this specification, the term "decoration" in relation to the present invention refers to any pattern, color, or gloss that is applied to the sheet surface of the base sheet laminate, including those described in the claims section. It means "decoration."

As the decoration, for example, coloring with lacquer or resin, pattern with metal foil or metal powder, multicolor pattern or pictorial pattern by printing or sealing, or transfer method using stamping foil, etc. can be advantageously applied.

In the present invention, base sheets include Japanese paper, plastic film, cloth coated with resin or impregnated on the entire surface or at least the surface layer, plastic film pasted on Japanese paper, and cloth and Japanese paper pasted together. etc. can be used to advantage. These base material sheets can be laminated with any material,
A base sheet laminate having two or more layers may be used.

In the present invention, the decoration applied to the base sheet laminate may be in the same position and in the same pattern as the pattern of the heat-foamable resin interposed in the intermediate layer of the base sheet laminate as the cut foil original. preferable. According to this, by heating and foaming the resin, only the decorative area on the surface of the cut foil of the fabric into which the cut foil of the present invention is woven is raised on the fabric, and the decoration with the three-dimensional pattern can be effectively expressed.

In the present invention, if necessary, a very thin film as a protective layer may be attached over the decoration of the base sheet laminate.

When the cut foil of the present invention is used as warp foil or hikihaku, it is heated by an appropriate method such as hot air at an appropriate location during the process of weaving it into a fabric, for example, at a location immediately before or after the reed, or after weaving. It is sufficient to heat the cut foil to foam the heat-foamable resin in the cut foil, thereby creating a three-dimensional decoration or pattern on the fabric.

Function The resin heated and foamed in the present invention becomes spongy by foaming, and improves the feel of the cut foil of the patterned portion made of the resin. In addition, as described above, the resin is present in the intermediate layer in a non-three-dimensional form before slitting the original sheet of cut foil, which eliminates the conventional troubles during slitting and improves workability. Also, during weaving, before foaming, it will not get caught in the thread guide, and even after foaming, the base sheet will be on the front and back sides, and the patterned parts made of resin will be three-dimensional with blunted edges. Therefore, there are few problems. Therefore, in the present invention, the degree of unevenness of the three-dimensional decoration or pattern can be made larger than that of the conventional art.

In the present invention, before foaming the resin, the original cut foil is slit to make the cut foil, so the resin is foamed in the cut foil. Therefore, regardless of whether the resin is in the middle layer of the original cut foil, during foaming, the generated gas is not trapped inside and is released from the slit end face of the cut foil, ensuring a good foamed spongy state of the resin. .

Effects of the Invention As described above, according to the present invention, it is possible to provide a cut foil and a cut foil original fabric that have the ability to weave three-dimensional decorations or patterns, eliminating the problems caused by the prior art described above.

Furthermore, in the present invention, the feel of the cut foil in the three-dimensional pattern can be improved by making the resin into a foamed sponge.
