Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a darning hole reinforcing material for reinforcing the periphery of a darning hole, such as a buttonhole or a string hole, and a method for manufacturing the same.

Conventional technology: Traditionally, when creating buttonholes or string holes for clothing, a reinforcing material called an adhesive core is hot-bonded to the area where the sewing hole will be made, and then the sewing thread is threaded using a sewing machine. Sometimes a procedure is adopted in which the holes are cut while sewing.

This adhesive interlining is made by applying a heat-fusible adhesive over the entire surface of one side of the base fabric, and after spreading it and flattening it,
It is cut to an appropriate shape and size, placed over the product at the location where the overlock hole is to be made, and is adhered to the product by pressing and heating it with an iron or the like.

The product with the adhesive interlining attached is then sent to a sewing machine, where the sewing machine uses a hole sewing machine to stitch the product and create holes.

[Problem to be solved by the invention]

In the past, as mentioned above, the work of spreading, cutting, gluing, etc. of the adhesive interlining and the damage to the sewing machine were done separately, which resulted in low work efficiency and a large amount of manpower. .

In addition, there is also the problem that the shapes and sizes of the cut remaining portions of the remaining overhole reinforcing material are scattered, making it difficult to organize them.

Furthermore, if the sewing work continues for a long time, the adhesive of the adhesive core will adhere to the sewing machine needle and thread scalpel of the sewing machine, making it difficult to perform the sewing work properly and reducing work efficiency.

The present invention has been made in view of the above circumstances, and there is no need to cut or iron the reinforcing material when installing the reinforcing material, and it can be easily installed.
The object of the present invention is to provide a darning hole reinforcing material and a method for manufacturing the same, which makes it easy to organize the reinforcing material and prevents a decrease in the efficiency of sewing machine work due to the adhesion of adhesive to sewing machine needles and thread scalpels. be.

[Means to solve the problem]

In order to achieve the above object, the overhole reinforcing material according to the present invention has a base fabric 3 cut into a predetermined shape and a back surface of both sides of the base fabric 3, as shown in FIG. 1(f), for example. It consists of a strong adhesive type adhesive 2 applied.

Furthermore, the method for producing a reinforcing material for overcut holes according to the present invention achieves the above object by applying a strong adhesive 2 to a base fabric 3 at appropriate intervals, as shown in FIG. 1, for example. After applying the adhesive in stripes and pasting the release paper 1 together, the procedure is to cut the base fabric 3 along the cutting line 4 set at the area where the adhesive 2 is applied.

[For production]

According to the method for manufacturing the overhole reinforcing material according to the present invention, the base fabric 3 and the release paper 1 are bonded together with the strong adhesive type adhesive 2 applied in stripes to the base fabric 3, and the base fabric 3 is attached to the release paper 1. Since it is cut along the cutting lines 4 set at the locations where the adhesive 2 is applied, the darning hole reinforcing material P with the strong adhesive 2 attached to the back side of both sides of the base fabric 3 is placed between each cutting line 4. will be formed,
In addition, a large number of each overhole reinforcing material P is supported on the release paper 1 in a state where it is lined up with the cutting line 4 as a boundary.

Since the adhesive 2 is not attached to the back side of the central part of this overhole reinforcing material P, it can be easily peeled off from the release paper 1 by hooking a nail to the central part, resulting in a single overfill hole reinforcing material P.
can be obtained.

Since the remaining overhole reinforcing material P remains attached to the release paper 1 having a fixed shape, it can be easily organized by organizing the release paper 1 to which the overhole reinforcing material P is pasted.

The removed darning hole reinforcing material P is placed in the desired position of the garment,
For example, it is temporarily fixed by pressing lightly at the position where a button hole or string passing hole is to be formed, and then the buttonhole reinforcing material P is used to cut the button hole or string passing hole while sewing the stitching thread with a stitching machine. This results in a reinforced buttonhole or string hole.

In this sewing machine, the adhesive 2 is not applied to the central part of the hole reinforcing material P where the needle and thread knife of the sewing machine come into contact, so the adhesive 2 does not adhere to the sewing machine needle or thread knife. become.

〔Example〕

Embodiments of the present invention will be described below based on the drawings.

FIG. 1 is a flowchart of a method for manufacturing a drill hole reinforcing material according to an embodiment of the present invention.

In this method, first, as shown in FIG. 5A, a release paper 1 cut into a predetermined shape, for example, a strip shape, is prepared.

The release paper 1 used in the present invention may be a sheet of paper or synthetic resin whose surface is treated with paraffin processing on one side so that the strong adhesive 2 can be attached in a removable manner. . Here, a release paper 1 having the above-mentioned surface treatment applied to one side of the paper is used.

Note that the release paper 1 is stored in a roll and is unrolled from the roll by the required length.

In addition, as shown in Figure (b), a strong adhesive 2 is applied at a predetermined interval on the back side (the surface facing the paper in the figure) of the base fabric 3, which is formed in approximately the same shape as the release paper 1. Leave it on and apply it in stripes.

The material of the base fabric 3 used in the present invention is not particularly limited, and for example, natural fibers, chemical fibers, composite fibers, etc. can be used. Here, acetate, which is relatively easily available, is selected as the material for the base fabric 3.

Further, the structure of the base fabric 3 used in the present invention is not particularly limited, and for example, a woven fabric, a knitted fabric, a nonwoven fabric, a weft-inserted fabric, etc. can be used. In this example, the most common fabric among these was selected as the texture of the base fabric 3.

The base fabric 3 is also stored rolled up in the same way as the release paper 1.
The same length as the release paper 1 is unrolled from the roll.

The strong adhesive type 2 used in the present invention is:
Peel strength when using standard adherend is approximately 800-100
It refers to a type of adhesive that has a weight of 0 g/25 mm or more and has tackiness at room temperature. In this example, an acrylic emulsion type adhesive with excellent sticky cutting properties is used.

The method of applying the adhesive 2 to the back surface of the base fabric 3 is not particularly limited, and for example, it can be applied by bringing a roll coater, a comb-like blade, etc. into contact with the base fabric 3 that has been unwound from a roll. .

After applying the adhesive 2 to the base fabric 3, the release paper 1 and the base fabric 3 are stacked vertically as shown in FIG. By applying appropriate pressure, the release paper 1 is releasably attached to the base fabric 3.

After attaching the release vertebra 1 to the base fabric 3, turn it upside down and cut the base fabric 3 along the cutting line 4 set at the application point of the adhesive 2, as shown in Figure (d). Cut along a cutting line 5 set in a perpendicular direction.

Furthermore, it is not essential to the present invention that the base fabric 3 has the same shape as the release paper 1; for example, if a tape-shaped base fabric 3 is used, the base fabric 3 may be shaped in a direction perpendicular to the direction in which the stripes of the adhesive 2 extend. A large number of base fabrics 3 extending in the same direction may be attached in parallel at appropriate intervals in the direction in which the stripes of the adhesive 2 extend.

The cutting lines 5 set in a direction perpendicular to the direction in which the stripes of the adhesive 2 extend are alternately wide and narrow, and are set to intersect with the cutting lines 4 in a grid pattern.

The method for cutting the base fabric 3 is not particularly limited, but since it is possible to cut only the base fabric 3 without cutting the release paper 1 and to cut along a large number of cutting lines 4 and 5 at once, it is possible to cut the base fabric 3 at once. 3 is recommended to be cut by punching with a die 6 such as a roll die or a stamping die. In this embodiment, a stamping die 6 is used to cut the base fabric 3.

After that, the narrow parts of the cutting lines 5 set perpendicular to the direction in which the stripes of the adhesive 2 extend are removed, and as shown in FIG. A sheet to which the reinforcing materials P are adhered in an orderly arrangement is obtained.

Each darning hole reinforcing material P is easily peeled off from the release paper 1 by hooking a nail to the center of each darning hole reinforcing material P located between the stripes of the adhesive 2 and pulling it. The overcast hole reinforcing material P peeled off from the release paper 1 is shown in the same figure (
As shown in f), a base fabric 3 cut into a predetermined shape;
A strong adhesive 2 applied to the back side of both sides of the base fabric 3
It is made up of.

Since the over-hole reinforcing material P left on the release paper 1 remains attached to the release paper 1 of a certain shape, by organizing the release paper 1 to which the over-hole reinforcing material P is attached,
Easily organized.

Further, the removed darning hole reinforcing material P is temporarily fixed by lightly pressing it at a desired position of the clothing, for example, at a position where a buttonhole or a string hole is to be formed. Then, while sewing using a hole sewing machine, a button hole or a string passing hole, etc., is cut with the thread knife of the hole sewing machine, thereby obtaining a button hole or a string passing hole reinforced with the hole reinforcing material P. .

Therefore, there is no need to cut or iron the reinforcing material when installing the reinforcing material P, and the reinforcing material P can be installed easily and in a short time, increasing the efficiency of making the reinforcing material P. Not only can this be greatly improved, but it can also save manpower.

In addition, since the adhesive 2 is not applied to the center of the reinforcing material P for the hole that is hung by the sewing machine or into which the thread knife is cut, the adhesive 2 will not adhere to the sewing machine needle or thread knife of the thread knife. , it is possible to form a darning hole as easily and simply as a darning hole that does not use the reinforcing material P, and prevents a decrease in work efficiency due to adhesive adhesion to sewing machine needles and thread scalpels over a long period of time. be able to.

〔Effect of the invention〕

As described above, according to the darning hole reinforcing material of the present invention, it can be temporarily secured by placing it in a desired position of clothing, such as a position where a buttonhole or a string hole is to be formed, and pressing it lightly. Then, by sewing the area where the darning hole reinforcing material has been temporarily attached using a darning sewing machine and cutting a button hole or string passing hole, a button hole or a string passing hole reinforced with the darning hole reinforcing material can be obtained. Become. Therefore,
There is no need to cut or iron the reinforcing material when installing the reinforcing material, and the over-hole reinforcing material P can be installed easily and in a short time, improving the efficiency of creating over-holes on the stairs. At the same time, it is possible to save manpower.

Furthermore, according to the method for producing a burrow reinforcing material of the present invention, it is possible to obtain a sheet in which the burrow reinforcing materials are arranged in an orderly manner on a release paper and held in a releasable manner, and each burrow reinforcing material can be easily separated. In addition to being able to be used after being peeled off from the release paper, the remaining overhole reinforcing materials can be kept neatly lined up on the release paper, and by organizing the release paper 1 to which the remaining overhole reinforcing materials are attached, Can be organized.

Furthermore, since the adhesive does not adhere to the sewing machine needle or thread knife of the hole sewing machine, it is possible to prevent a decrease in work efficiency due to adhesive adhesion to the sewing machine needle or thread knife.
