Description

[Detailed explanation of the idea] The present invention relates to appliqués or marks.

More specifically, the present invention is composed of a synthetic resin base layer having hot melt adhesive properties, an adhesive layer coated on the base layer, and a flocked layer treated with flocking on the adhesive layer, and the synthetic resin This invention relates to an appliqué or mark made of a flocked laminate in which dyes and pigments having hiding power are added to the base layer.

An example of a conventional flocked laminate is the number on the back of a baseball uniform.

This jersey number consists of a fiber base layer (cloth), a formanon-curing adhesive layer coated on the base layer, a flocked layer in which monofilament is directly flocked onto the adhesive layer, and a fiber base layer coated on the lower surface of the fiber base layer. and a pressure sensitive adhesive or hot melt adhesive layer.

Then, the uniform number is attached at a predetermined position with the pressure sensitive adhesive or hot melt adhesive layer on the uniform side.

However, the flocked laminate used as jersey numbers has a problem in that there is a limit to its thinness because the base layer is a fiber layer (cloth).

One of the main objects of the present invention is to provide an appliqué or mark made of a flocked laminate that solves these problems.

Another main purpose of the present invention is that the color of the adherend, such as a baseball uniform, can be hidden, thereby allowing the color of the laminate itself to be revealed without changing. The present invention provides an applique or mark made of a flocked laminate.

Another object of the present invention is to provide an appliqué or mark made of a flocked laminate whose manufacturing process is greatly simplified.

Another object of the invention is to provide an appliqué or mark made of a flocked laminate that can be produced at a very low cost.

Yet another object of the present invention is to provide an appliqué or mark made of a flocked laminate that can be attached (adhered) to a predetermined location in a short time under low heating temperature conditions.

One of the main structural features of the flocked laminate constituting the applique or mark according to the present invention is that it is composed of three layers: a synthetic resin base layer with hot melt adhesive properties, an adhesive layer, and a flocked layer. It lies in being done.

In other words, it does not have the fiber base layer of conventional flocked laminates.

Another major structural feature of the flocked laminate constituting the applique or mark according to the present invention, which is the most important point in the present invention, is that dyes and pigments with hiding power are added to the synthetic resin base layer. It's what I did.

The flocked laminate constituting the applique or mark according to the present invention is usually formed into a sheet or film shape,
Furthermore, it may be formed into a tape shape.

The flocked laminate is then cut into a suitable shape and bonded as it is to an adherend such as cloth or leather under heat and pressure.

For example, it can be suitably used as numbers on baseball uniforms, appliques or marks on children's clothes, bags, etc.

In the present invention, synthetic resins with hot-melt adhesive properties refer to synthetic resins that can be attached to cloth, leather, etc. by heating and pressurizing, such as vinyl resins such as ethylene-vinyl acetate copolymer resins, polyethylene resins, etc. Polyolefin resins such as nylon 6/66/12
Examples of the resin include those commonly used for hot melt adhesives, such as polyamide resins represented by nylon 6/66/610.

Particularly preferred is a tertiary or higher copolyamide resin which can be heat-sealed at low temperatures and has wash resistance, which has been recently developed for use as a hot melt adhesive for fibers.

Specific examples of the copolyamide resin include copolyamide resins composed of ε-caprolactam, hexamethylene diammonium adipate, laurin lactam, or hexamethylene diammonium sebacate (
(see Japanese Patent Publication No. 45-22240), a copolyamide resin composed of ε-caprolactam, laurin lactam, hexamethylene diammonium adipate, and hexamethylene diammonium sebacate (Japanese Patent Publication No. 1983-1999)
-22034), and other Japanese Patent Laid-Open No. 167-165
No. 99, JP-A-50-35290, JP-A-50-35
Examples include copolyamide resins disclosed in No. 291 and JP-A-50-45091.

Note that two types of synthetic resin base layers having hot melt adhesive properties may be laminated together.

One example is a combination of ethylene-vinyl acetate copolymer resin and boamide resin.

In the present invention, dyes and pigments are added to the synthetic resin base layer having hot melt adhesive properties as described above in order to impart concealing properties to adherends.

That is, dyes and pigments having hiding power are added to the synthetic resin base layer so that the color of the adherend to which the flocked laminate is not strongly influenced through the flocked laminate.

When there are two types of synthetic resin base layers, dyes and pigments may be added to either one or both.

For example, when the synthetic resin layer contains a hot norl-adhesive made of a nylon resin such as nylon 6/66/12, the vinyl acetate content is 10 to 30% (wt%) to impart this hiding property. 1 to 1 part of ethylene vinyl acetate copolymer resin per 100 parts by weight of the nylon copolymer resin.
Examples include those containing 0 parts by weight and further blending 3 to 15 parts by weight of fine titanium oxide powder with strong hiding power.

Other dyes and pigments with strong hiding power include black (for example, Toyo Dry Color TN-0643), red (for example, Toyo Dry Color TN-4274), and blue (for example, Toyo Dry Color TN-7268).

Further, it is preferable to color the synthetic resin base layer with a dye and pigment of the same color as the monofilament for flocking.

This coloring allows the color of the monofilament to appear without discoloration, and furthermore, even if a wound (hair loss area) occurs in the hair transplant layer, it can be made less noticeable.

In other words, here, the dye and pigment of the same color as the monofilament for flocking processing means the dye and pigment of the same color or similar color to the monofilament for flocking processing, and the same color or similar color can be judged intuitively. .

Furthermore, the adhesive layer described below applied to the synthetic resin base layer can be colored with a dye or pigment.

In the present invention, the adhesive applied to the synthetic resin base layer having hot-melt adhesive properties is not particularly limited, and any adhesive that can generally be used for flocking can be used.

However, it is necessary to select an adhesive that takes into account the heat resistance of the synthetic resin base layer.

For example, a room temperature curing adhesive is used.

In this invention, the flocking layer that is processed directly on the adhesive layer is a general monofilament made by cutting and dyeing acrylic, nylon, etc. Or, the hair is directly transplanted using the electric flocking method).

The invention will be illustrated below based on the embodiments shown in the figures.

Note that the present invention is not limited by this.

1 is a flocked laminate, which is composed of a synthetic resin base layer 2 having hot-melt adhesive properties, an adhesive layer 3 coated on the base layer, and a flocked layer 4 directly processed on the adhesive layer. has been done.

The synthetic resin base layer 2 includes a nylon copolymer resin with hot melt adhesive properties made of nylon 6/66/12 (constituent weight ratio: 30/30/40, melting point: 115°C, transparent), and has a vinyl acetate content. is 10-30% (weight%
5 parts by weight of the ethylene-vinyl acetate copolymer resin of ) was added to 100 parts by weight of the nylon copolymer resin, and 10 parts by weight of titanium oxide fine powder was further blended.
It is a 1 mm white opaque film.

The adhesive layer 3 is made of a synthetic rubber resin containing acrylonitrile-butadiene as a main component and has a thickness of about 5 microns.

The flocked layer 4 is formed by directly flocking white monofilaments made of nylon using an electrostatic flocking method.

The thickness is approximately 1 mm.

The flocked laminate 1 constructed as described above was cut into a suitable shape and could be adhesively fixed to cloth in about 5 to 10 seconds by heating and applying pressure with an ordinary iron.

The color of the flocked laminate 1 remained the same as the white color of the monofilament of the flocked layer 4.

Similar results were obtained even when the color of the monofilament and the dye and pigment added to the synthetic resin base layer were changed as follows in the above examples.

Monofilament color・・・・・・Dye and pigment
(Color) Blue ...... Toyo Dry Color (Blue) TN-7268 Red ...... Same as above (Red)
