BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an embroidery reinforcing material used as a material for embroidering.

[0002]

2. Description of the Related Art In the case of embroidering a thin cloth or a coarse cloth, a reinforcing material is generally applied to the cloth for the embroidery.

Conventionally used embroidery reinforcements are mainly woven fabrics, non-woven fabrics, films, etc. made of water-soluble materials. After embroidering, the embroidery reinforcements are dissolved in water and removed from the cloth. are doing.

[0004]

As described above, woven cloth, non-woven cloth, film and the like have been conventionally used as the reinforcing material for embroidery, but each reinforcing material has the following drawbacks. .

That is, when the reinforcing material is a woven fabric, the required longitudinal and transverse strengths for embroidery can be obtained, but the weaving cost is high.

When the reinforcing material is a non-woven fabric, it is necessary to increase the basis weight required for embroidery, which makes it bulky and difficult to handle, and it may take a long time to dissolve it in a subsequent process.

When the reinforcing material is a film, it is not suitable when the embroidery density is high because the strength required for using the film is insufficient, and the use is limited.

[0008] The present invention is to solve the above-mentioned drawbacks of the embroidery reinforcing material used in the related art.

[0009]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention forms intermittent cuts substantially parallel to the stretching direction on a water-soluble film stretched in one direction and widens the cuts. A net-like film and a water-soluble film stretched in one direction are intermittently formed with cuts substantially parallel to the drawing direction, the cuts are widened, and a net-like film in which the draw direction intersects with the net-like film, and nylon. The knitted fabric was formed into a reinforcing material for embroidery by laminating and integrating the mesh film and the nylon knitted fabric.

In addition, cuts substantially parallel to the stretching direction are intermittently formed in the water-soluble film stretched in one direction, and the cuts are opened to form a mesh film and a water-soluble film stretched in one direction. Intermittently forming substantially parallel cuts, widening the cuts, a mesh film in which the stretching directions intersect with each other in the mesh film, and a nonwoven fabric made of a water-soluble resin, and the mesh film and the nonwoven fabric Adopted a structure in which the two are laminated and bonded together.

[0011]

Since the present invention is constructed as described above, the intersecting axes of stretching produce the longitudinal and lateral strength required for embroidery.

[0012]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below based on the embodiments shown in the drawings.

(First Example) Polyvinyl alcohol (PVA) was added at 150 ° C to 18 ° C.
It is melted at 0 ° C., formed into a sheet from a T die by an extrusion molding machine, and wound up. Then, the above film is stretched by a stretching machine at a stretching temperature of 20 ° C. to 50 ° C. and a stretching ratio of 1.1 to 6.
It is uniaxially stretched to 0 times and wound up. The stretched film is 2
It has a thickness of 0 to 70 μm, is hot-air heated in the next heat treatment tank, is heat set, and is wound.

The heat-set film is intermittently formed with slitters substantially parallel to the stretching direction, expanded in the width direction, and wound into a reticulated film.

Next, the reticulated film is pulled out and run, and the PVA adhesive is applied onto the reticulated film, and the film is uniaxially stretched at a stretching ratio of 1.1 to 6.0, and cuts are cut substantially parallel to the stretching direction. Formed, then expanded in the width direction and heat set, and another net-like film is laminated and adhered while being cut into a predetermined length from the orthogonal direction, and integrated and wound.

Next, a nylon knit is laminated on the two mesh films and the edges of both are sewn with a sewing machine to be integrated.

FIG. 1 shows a reinforcement material for embroidery manufactured according to the first embodiment. Here, 1 and 2 are reticulated films, 3 is a nylon knitted fabric, and a and b are stretching directions.

When the embroidery reinforcing material manufactured in this way is embroidered by using a cotton thread or the like by a lace machine, the embroidery reinforcing material has a shape-retaining property. Without, the embroidery pattern does not shift.

The reticulated film in the embroidery reinforcement material with the embroidery pattern is immersed in water at 60 ° C. to 80 ° C. to shrink, swell, and dissolve to obtain the desired embroidery material. When embroidering the embroidery reinforcing material with a lace machine, a so-called bridging thread is formed in which the thread end crosses over the embroidery reinforcing material from the edge of the embroidery reinforcing material to the embroidery pattern. After cutting with a cutter, the residual yarn is sucked with suction air to perform sharing, and the crossover yarn is completely removed.

(Second Embodiment) Polyvinyl alcohol (PVA) was added at 150 ° C. to 18 ° C.
It is melted at 0 ° C., formed into a sheet from a T die by an extrusion molding machine, and wound up. Then, the above film is stretched by a stretching machine at a stretching temperature of 20 ° C. to 50 ° C. and a stretching ratio of 1.1 to 6.
It is uniaxially stretched to 0 times and wound up. The stretched film is 2
It has a thickness of 0 to 70 μm, is hot-air heated in the next heat treatment tank, is heat set, and is wound.

The heat-set film is intermittently formed with slitters substantially parallel to the stretching direction, expanded in the width direction, and wound into a reticulated film.

Then, the reticulated film is pulled out and run, and the reticulated film is coated with a PVA adhesive and uniaxially stretched at a stretching ratio of 1.1 to 6.0, and cuts are made substantially parallel to the stretching direction. Formed, then expanded in the width direction and heat set, and another net-like film is laminated and adhered while being cut into a predetermined length from the orthogonal direction, and integrated and wound.

On the other hand, a nonwoven fabric made of polyvinyl alcohol (PVA) is prepared. As a method of manufacturing a non-woven fabric,
The PVA fiber web may be partially thermocompressed or manufactured by the needle punching method, or the PVA filament may be entangled by the spunpond method. The thickness of the non-woven fabric is about 0.1 to 1 mm, and the basis weight is 10 g.
To 100 g / m ² .

The above-mentioned non-woven fabric having a PVA adhesive is laminated and adhered to the above-mentioned laminated reticulated film to be integrated and wound.

The one shown in FIG. 2 is a reinforcement material for embroidery manufactured according to the second embodiment. Here, 1 and 2 are reticulated films, 4 is a non-woven fabric, and a and b are stretching directions.

When the embroidery reinforcing material manufactured in this manner is embroidered with a cotton thread or the like by a lace machine, the embroidery reinforcing material has a shape-retaining property, so that the embroidery reinforcing material does not stretch or shift during embroidery. The embroidery pattern does not shift.

The reticulated film in the embroidery reinforcing material with the embroidery pattern is immersed in water at 60 ° C. to 80 ° C. to shrink, swell, and dissolve to obtain a desired embroidery cloth. When embroidering the embroidery reinforcing material with a lace machine, a so-called bridging thread is formed in which the thread end crosses over the embroidery reinforcing material from the edge of the embroidery reinforcing material to the embroidery pattern. After cutting with a cutter, the residual yarn is sucked with suction air to perform sharing, and the crossover yarn is completely removed.

[0028]

Since the present invention is constructed and operates as described above, it has a strength equal to or higher than that of a woven cloth due to the intersecting stretching axes, and the vertical and horizontal strengths required for embroidery can be obtained. Can hold enough. Therefore, since the shape-retaining property of the embroidery reinforcing material is good, the embroidery pattern does not shift during embroidery.

Since a reticulated film is used,
Since it is lightweight and the amount used per unit area is small, the cost can be reduced, and the dissolution is quick and the working efficiency can be improved.

Furthermore, since the net-like film has good air permeability, the bridging yarn can be sucked with suction air to be napped, and shaling is easy.
