Description

The present invention relates to a process for the preparation of plasters for X-ray detection and Contact plasters for X-ray detection.
In particular, the X-ray detectors, accurately detectable X-ray detection material containing organic fabric the X-ray detection bandage used, and X-ray method for producing detection bandage using such X-ray detection material containing fabric About.

Conventionally, a bandage that can be detected by a metal detector has been proposed in order to detect when the bandage or the like is detached and mistakenly mixed with food or the like.
More specifically, as shown in FIGS. 6 (a) to 6 (b), in an emergency adhesive plaster 101 having a pressure-sensitive adhesive layer 105 with a primer layer 104 and a pad 106 on a support 102. An emergency adhesive plaster 101 in which a metal material 103 is disposed on a part of a body 102 (see, for example, Patent Document 1). Examples of the support 102 include a resin film mixed with the metal material 103, a synthetic fiber and a woven product of metal fibers, and a metal powder interposed between the fibers.
Further, as shown in FIGS. 7A to 7B, a metal layer (metal particle adhesion layer) 203 is formed on the surface of the tape 202 having flexibility and stretchability to such an extent that the stretchability of the tape 202 is not impaired. An adhesive bandage 201 formed by integrally forming a film has been proposed (see, for example, Patent Document 2).
No. 3-13304 (Scope of request for registration of utility model) JP 2006-6669 (Claims)

However, since the emergency bandage disclosed in Patent Document 1 has a metal material uniformly disposed on a part of a support that forms a base material, the type and form of the metal material are limited, and an X-ray detector is used. There was a problem of low sensitivity to.
Moreover, although the tape disclosed by patent document 2 has the metal layer (metal particle adhesion layer) laminated | stacked on the base-material surface to such an extent that the elasticity is not impaired, a metal layer peels from the base-material surface. There was a problem that not only the sensitivity to metal detectors was likely to vary, but also the sensitivity to X-ray detectors was low.
On the other hand, in the conventional emergency bandage, in order to increase the sensitivity to the X-ray detector, when trying to add metal particles or metal fibers having a large average particle diameter in the base material, the stretchability of the emergency bandage is significantly impaired. There was a new problem that it was difficult to place in a predetermined position or a foreign object sensation was generated.

Therefore, the present inventor configures the absorbent pad from a cloth containing a predetermined X-ray detection material, so that the sensitivity to the X-ray detector as shown in FIG. When used, the present invention has been completed by finding that the stretchability of the adhesive bandage is not impaired and the X-ray detection material is hardly detached from the absorption pad.
That is, an object of the present invention is to provide a bandage for X-ray detection that does not impair the stretchability of a bandage having an X-ray detection material-containing fabric having high ground detection sensitivity with respect to an X-ray detector as an absorbent pad of the bandage, and It is providing the efficient manufacturing method of the adhesive bandage for a detection.

According to the present invention , an adhesive protective member comprising a base material and an adhesive layer, an absorbent pad provided at a predetermined location on the adhesive protective member, and made of an X-ray detection material-containing fabric having a predetermined length; A bandage for X-ray detection having the above is provided, and the above-mentioned problems can be solved.
That is, since the X-ray detection material is entirely or partially covered with the covering, the X-ray detection material moves from the place in the cloth (including the inside of the cloth and the cloth surface; the same applies hereinafter). In addition, the risk of dropping off is reduced. Therefore, when a bandage with an X-ray detection material-containing fabric as an absorbent pad is mistakenly mixed into a metal package, the metal detector cannot detect it, but absorbs the X-ray detection material-containing fabric of the present invention. If it is an adhesive bandage as a pad, it can be accurately detected by an X-ray detector.
In addition, since the X-ray detection material covered with the covering is substantially arranged at a predetermined interval, the sensitivity to the X-ray detector does not vary, and a high sensitivity can be reliably obtained.
In addition, it is possible to accurately recognize not only the presence / absence (existing position) of the X-ray detection material but also the non-existing position where the X-ray detection material does not exist. Therefore, when processing a cloth containing an X-ray detection material by a cutting device such as a cutter or a knitting device such as a stitch bond, damage to the cutting device or the knitting device caused by the X-ray detection material is effectively prevented. Can do.
Furthermore, since the X-ray detection materials covered with the covering are arranged at predetermined intervals, it is possible to provide a bandage that has high ground detection sensitivity to the X-ray detector and that does not impair the stretchability.
At the stage of the cloth containing the X-ray detection material, a plurality of X-ray detection materials are prepared and arranged at predetermined intervals, but at the stage of processing into the shape of the absorption pad, at least one X-ray detection material is used. It only needs to include the material.

Moreover, in constituting the bandage for X-ray detection of the present invention, it is preferable that the X-ray detection material is disposed as a long object that is entirely or partially covered with a covering made of fibers .
By comprising in this way, the X-ray detection material processed into the elongate thing can be knitted in the nonwoven fabric as one of the fabrics, for example by the stitch bond method, and in such a nonwoven fabric, it is in a predetermined position. While being able to arrange easily and accurately, the possibility of dropping off is further reduced.

In forming the adhesive bandage for X-ray detection of the present invention , the covering is made of polyester fiber, polyamide fiber, polyacryl fiber, polyolefin fiber, polyurethane fiber, polyacetal fiber, polyvinyl alcohol fiber, rayon fiber, cotton fiber, pulp. It is preferably composed of at least one fiber selected from the group consisting of fibers and polyvinyl chloride fibers.

Moreover, in constructing the bandage for X-ray detection of the present invention, it is preferable that the X-ray detection materials are arranged at regular intervals in the range of 3 to 60 mm in a long object .
With this configuration, the X-ray detection material can be easily arranged, and even when some force is applied to the X-ray detection material, it can be effectively prevented from shifting from the predetermined position.
In addition, since it is arranged at equal intervals in such a range, the sensitivity to the X-ray detector does not vary, and a high sensitivity is surely obtained, as well as a non-existing position where no X-ray detection material is present. Can be recognized more accurately.
Therefore, the predetermined sensitivity with respect to the X- ray detector can be stably maintained by such an adhesive bandage for X- ray detection.
In addition, since the length of the adhesive bandage for X-ray detection is usually about 70 mm, if the X-ray detection materials are arranged at equal intervals in the range of 3 to 60 mm, the X-ray detection bandage is always placed on a part of the adhesive bandage. It is also a preferable numerical range because of the presence of the line detection material.
On the other hand, if the X-ray detection material-containing fabric is used for other purposes, the arrangement interval of the X-ray detection materials may be a value exceeding 60 mm, for example, a value in the range of 65 to 100 mm.
Furthermore, in the X-ray detection material-containing fabric, the need for the X-ray detection materials to be arranged at equal intervals is reduced. For example, a 10 mm interval arrangement, a 20 mm interval arrangement, and a 30 mm interval arrangement coexist. May be.

Even non-metallic materials such as bones, rubber pieces, resin pieces, glass, shells, and stones have a predetermined density and can provide a predetermined sensitivity to X-ray detectors. It is possible to construct an adhesive bandage for X-ray detection that is lightweight and easy to hold inside.

Moreover, when comprising the bandage for X-ray detection of this invention, when an X-ray detection material is spherical, it is preferable to make the average particle diameter into the value within the range of 0.1-3 mm.
With this configuration, a predetermined sensitivity for the X-ray detector can be obtained.
Further, if the X-ray detection material is spherical, a predetermined sensitivity can be obtained regardless of the angle at the time of detection.

Moreover, when comprising the bandage for X-ray detection of this invention, when an X-ray detection material is a linear thing, it is preferable to make the average length into the value within the range of 0.3-10 mm.
By configuring in this way, the sensitivity of the X-ray detector can be increased, but since it is easy to arrange in the plane direction, when used as an absorbent pad in a bandage, it reduces the sensation of foreign matter and functions in the absorbent pad The decrease can be reduced.

By comprising in this way, the fixability of the X-ray detection material in a cloth containing an X-ray detection material can be improved, and it can be effectively prevented from shifting from a predetermined position.
In addition, since the predetermined X-ray detection material is sandwiched from above and below by a plurality of fabrics (the first fabric and the second fabric), the X-ray detection material can be configured not to be recognized from the outside. When used as an absorbent pad in a bandage, the feeling of foreign matter can be further eased.

Moreover, in constructing the adhesive bandage for X-ray detection of the present invention, it is preferable that the elongation percentage of the base material (conforming to JIS-L-1096) in the adhesive protection member is 120% or more.

[ First Reference Embodiment ]
As shown in FIGS. 1A to 1B, the first reference embodiment of the present invention includes two woven fabrics or non-woven fabrics 10 (10a, 10b) composed of a first fabric and a second fabric. during, while being entirely or partially covered by the coating 14 of fiber, the X-ray detection material comprising a long member 16 having an X-ray detection material 12 of spherical or linear shape are arranged at predetermined intervals This is the containing fabric 18.
FIG. 1A shows an example of an X-ray detection material-containing fabric 18 which is a long object 16 in which the X-ray detection material 12 is covered with a coating 14 and is arranged on the surface of the fabric 10. FIG. 1B shows an X-ray detection in which an X-ray detection material 12 as a long object 16 is knitted between two fabrics 10a and 10b made of a first fabric and a second fabric. This is an example of the material-containing fabric 18.
Hereinafter, the X-ray detection material-containing fabric 18 of the first reference embodiment will be specifically described for each configuration requirement.

1. Cloth The form of the cloth constituting the cloth containing the X-ray detection material is not particularly limited. For example, it can be obtained by a dry staple method, an air lay method, a melt blow method, a needle punch method, a stitch bond method, or a spun lace method. It is preferable that it is a fabric.
And as a form of this fabric, it is preferable that it is a nonwoven fabric comprised by the short fiber of 15-100 mm in length and 6-100 micrometers in diameter being entangled, for example.
Alternatively, for example, it is also preferable that a long fiber having a length of 1 to 100 m and a short fiber having a length of 15 to 100 mm are entangled to maintain a nonwoven fabric state.

Further, the thickness (non-compressed state) of the fabric is preferably set to a value within the range of 0.1 to 10 mm, more preferably set to a value within the range of 0.5 to 3 mm. It is more preferable to set the value within the range.
The reason for this is that, by setting the thickness of such a fabric, a good balance can be achieved between the predetermined handleability and the ease of weaving of a long object.
That is, if the fabric is excessively thin, the handleability of the fabric may be reduced, and it may be difficult to knit long objects. On the other hand, if the fabric is excessively thick, the handleability of the fabric may be reduced, and it may be difficult to knit long objects.
Moreover, if it is the thickness of such a fabric, it is because it can be used suitably as an absorption pad in a bandage.

Further, it is preferable that the weight of the fabric (the uncompressed state) within a range of 10 to 500 g / m ^2, more preferably to a value within the range of 30~300g / m ^2, 50~150g / More preferably, the value is within the range of m ² .
This is because, by setting the weight of such a fabric, it is possible to achieve a good balance between predetermined handleability and ease of knitting of a long object.
That is, if the fabric is excessively light, the handleability of the fabric may be lowered, and it may be difficult to knit long objects. On the other hand, if the fabric is excessively heavy, the handleability of the fabric may be reduced, and it may be difficult to knit long objects.

Further, it is preferable that a value within the range fabric bulk density (uncompressed) of 0.005 to 0.5 / cm ^2, to a value within the range of 0.01 to 0.1 g / cm ² It is more preferable that the value be in the range of 0.05 to 0.08 g / cm ² .
The reason for this is that by setting the bulk density of such a fabric, a good balance can be achieved between predetermined handling properties and easiness of weaving of long objects.
That is, if the value of the bulk density of the fabric is small, the handleability of the fabric may be lowered, and it may be difficult to knit long objects. On the other hand, when the value of the bulk density of the fabric becomes excessively large, on the contrary, the handleability of the fabric may be deteriorated, and it may be difficult to knit long objects.
Moreover, it is because the bulk density of such a fabric can be suitably used as an absorbent pad in a bandage.

The fabric is at least selected from the group consisting of polyester fiber, polyamide fiber, polyacrylic fiber, polyolefin fiber, polyurethane fiber, polyacetal fiber, polyvinyl alcohol fiber, rayon fiber, cotton fiber, pulp fiber, and polyvinyl chloride fiber. It is preferable that it is composed of one fiber.
The reason for this is not only that stable production as a fabric is facilitated by comprising such types of fibers, but, for example, when used as an absorbent pad in a bandage, the absorbability of body fluids and chemicals is excellent. Because.
In particular, the fabric is a non-woven fabric and is composed of a mixed fiber of rayon fiber and polyester fiber, a mixed fiber of polypropylene fiber and polyethylene resin, or a mixed fiber of polypropylene fiber and polyester fiber. If so, a good balance between lightness and durability can be obtained.

As shown in FIG. 1B, the fabric includes at least a first nonwoven fabric 10a (including a first fiber web layer; the same applies hereinafter) and a second nonwoven fabric 10b (second fibers). It is preferable that the long material 16 is knitted between the first nonwoven fabric 10a and the second nonwoven fabric 10b.
The reason for this is that it is easy to weave the X-ray detection material (X-ray detection material covered with a long object) and to effectively shift the X-ray detection material from a predetermined position. This is because it can be prevented.
Therefore, even when such an X-ray detection material-containing fabric is used as an absorption pad in an adhesive bandage, positional displacement of the X-ray detection material can be effectively prevented. As a result, the detection sensitivity with respect to the X-ray detector can be effectively increased regardless of whether it is mixed in a non-metallic package product or a metal package product.
An adhesive layer can be provided between the first nonwoven fabric and the second nonwoven fabric, or a third nonwoven fabric as a protective layer on the outer surfaces of the first nonwoven fabric and the second nonwoven fabric. It is also preferable to provide

2. Covering As shown in FIGS. 2 (a) to 2 (e), the X-ray detection material 12 covered entirely or partially by the covering 14 (14a, 14b) is arranged at a predetermined interval (L). It is characterized by being.
Here, FIG. 2A shows an X-ray detection material 12 having a substantially cylindrical shape (hereinafter sometimes referred to as a linear object) covered with a covering 14 from above and below and arranged at equal intervals. It is the cross-sectional schematic of the elongate object 16 formed.

FIG. 2B shows a long object in which a substantially cylindrical X-ray detection material 12 is covered from a peripheral direction by a covering 14 made of a plurality of filaments (fibers) and arranged at equal intervals. FIG.
In addition, as shown in FIG. 2B, the X-ray detection material 12 covered with the covering 14 made of a plurality of filamentous materials (fibers) may easily fall out of the covering. Therefore, as shown in FIGS. 3A to 3C, a film 14d once processed (bent) into a V-shape is prepared, and the X-ray detection material 12 is placed in the trough, and the state In this case, it is preferable to cover the periphery with a covering 14 made of a filamentous material (fiber).

Further, FIG. 2C shows that the substantially rectangular X-ray detection material 12 is disposed on the covering base material 14a as a part of the covering 14, and from the upper direction, Furthermore, it is the cross-sectional schematic of the elongate object 16 coat | covered with the resin 14b for a coating as a part, and arranged at equal intervals.
The form of the base material for covering 14a described in FIG. 2 (c) is not particularly limited, and examples thereof include PET film, acrylic film, urethane foam, polyethylene foam, silicon rubber, natural rubber, and the like. Is mentioned.
Further, the form of the generally rectangular X-ray detection material 12 shown in FIG. 2C is not particularly limited. For example, a metal foil or a metal plate having a uniform thickness is made to have a predetermined width. Can be obtained by cutting.

FIG. 2D shows that the flat (elliptical) X-ray detection material 12 is embedded in the inside 14c of the covering base material 14a as a part of the covering 14, and from above. FIG. 4 is a schematic cross-sectional view of a long object 16 that is covered with a coating resin 14b as a further part of the coating 14 and arranged at equal intervals.
The flat (elliptical) X-ray detection material 12 shown in FIG. 2D is made by flattening relatively soft spherical particles such as aluminum, copper, iron, and solder. Is preferred.

Further, FIG. 2 (e) shows a state in which the substantially cylindrical X-ray detection material 12 is embedded in the inside 14c of the covering 14, that is, partially covered so that the major axis direction intersects perpendicularly. It is the cross-sectional schematic of the elongate object 16 arranged at a space | interval.
In addition, as the substantially cylindrical X-ray detection material 12 shown in FIG. 2E, for example, a metal wire is preferably cut into a predetermined length.

That is, as shown in FIGS. 2A to 2E, as the X-ray detection material 12, a predetermined long object 16 processed by a covering is created, and the long object 16 is predetermined. By cutting into a length of X, a cloth containing an X-ray detection material that does not vary in sensitivity to the X-ray detector can be obtained.
Further, in the predetermined long object 16 shown in FIGS. 2A to 2E, the X-ray detection materials are discontinuous and arranged at equal intervals. When used, an X-ray detection material-containing fabric that does not impair the stretchability of the adhesive bandage can be provided.

In addition, as shown in FIG. 2A and the like, in a predetermined long object 16, the X-ray detection material 12 is covered and arranged with the covering 14 at equal intervals (L) in the range of 3 to 60 mm. It is preferable.
That is, it is preferable to make the predetermined space | interval (pitch) adjacent to the X-ray detection material included in a long thing into the value within the range of 3-60 mm, and it is more preferable to set it as the value within the range of 5-40 mm. Preferably, the value is in the range of 8 to 30 mm.
The reason for this is that it becomes easy to weave a predetermined long object in the X-ray detection material-containing fabric, and it is possible to effectively prevent the X-ray detection material from shifting from a predetermined position. Because.
Moreover, this is because such an adjacent interval between the X-ray detection materials can accurately recognize not only the position where the X-ray detection material exists but also the non-existence position therebetween. Therefore, when processing the cloth containing the X-ray detection material by the cutting device or the knitting device, damage to the cutting device or the knitting device can be prevented.
Therefore, by using the cloth containing the X-ray detection material contained in the long object at regular intervals in this way as an absorption pad in the adhesive bandage, the positional deviation of the X-ray detection material can be effectively prevented. As a result, the sensitivity to the X-ray detector can be stably increased.
Furthermore, since such X-ray detection materials are arranged at equal intervals, that is, there are cuts, for example, when used for an adhesive pad of an adhesive bandage, an X-ray detection material-containing fabric that does not impair the elasticity of the adhesive bandage Can be provided.

X-ray detection materials include iron (including plated iron), stainless steel, aluminum, copper, silver, solder (including lead-free solder), nickel, bone, rubber pieces, resin pieces, glass, shells, and stones. It is preferably at least one selected from the group consisting of
The reason for this is that, by using such an X-ray detection material, the sensitivity to the X-ray detector can be further increased, and as a fabric containing an X-ray detection material that is relatively inexpensive and easy to process into a predetermined shape. This is because it can be provided.
Even non-metallic materials such as bones, rubber pieces, resin pieces, glass, shells, and stones have a predetermined density and can provide a predetermined sensitivity to X-ray detectors. This is because an X-ray detection material-containing fabric that is light and easy to hold in the fabric can be configured.

However, iron (including plated iron) is more preferably used as the X-ray detection material because it is ferromagnetic, has higher sensitivity to X-ray detectors and metal detectors, and is inexpensive.
Although iron is generally easily rusted depending on environmental conditions, in the case of the present invention, iron exists in a long object in a state of being surrounded by a coating and is almost dry. It turns out not.
In addition, it is also preferable to use plated iron or stainless steel because sensitivity to an X-ray detector or a metal detector can be exhibited for a long time, or it can be easily slipped and further included in a long object.

  On the other hand, bone, rubber pieces, resin pieces, glass, shells, stones, or aluminum, copper, silver, and solder (including lead-free solder) are used to reduce the feeling of foreign objects when used as an absorbent pad in adhesive bandages. It is preferable that it is at least one of these. That is, these non-metal species and metal species are easily deformed when a predetermined force is applied, and are easily flattened.

In addition, the shape of the X-ray detection material is not particularly limited, but is usually preferably spherical or linear.
In that case, it is preferable to set the average particle diameter (sphere equivalent diameter) of the X-ray detection material to a value within the range of 0.1 to 3 mm.
The reason for this is that when the average particle size of the X-ray detection material is less than 0.1 mm, the detection sensitivity of the X-ray detector or metal detector may be significantly reduced. When the average particle size of the detection material exceeds 3 mm, when used as an adhesive pad of a bandage, the foreign material feeling may increase or it may be difficult to stably include in a long object. Because.
Therefore, it is more preferable to set the average particle diameter (sphere equivalent diameter) of the X-ray detection material included in the long object to a value within the range of 0.1 to 2 mm, and within the range of 0.2 to 1 mm. More preferably, the value is most preferably in the range of 0.3 to 0.8 mm.

When the X-ray detection material is linear, the average length is preferably set to a value within the range of 0.3 to 10 mm.
By comprising in this way, while the detection sensitivity by a X-ray detector or a metal detector can be raised, the functional fall in an absorption pad can be decreased.
Therefore, it is more preferable to set the average particle diameter of the linear X-ray detection material included in the long object to a value within the range of 0.4 to 8 mm, and a value within the range of 0.5 to 5 mm. More preferably.
In addition, about a linear diameter (wire diameter), it is preferable to set it as the value within the range of 0.01-5 mm, for example, and it is more preferable to set it as the value within the range of 0.1-3 mm. More preferably, the value is in the range of 5 to 1 mm.

Further, the coating is selected from the group consisting of polyester fiber, polyamide fiber, polyacrylic fiber, polyolefin fiber, polyurethane fiber, polyacetal fiber, polyvinyl alcohol fiber, rayon fiber, cotton fiber, pulp fiber, and polyvinyl chloride fiber. It is preferably composed of at least one fiber selected from the group consisting of at least one fiber.
The reason for this is that the composition of such fibers facilitates knitting into the fabric and facilitates recognition of the X-ray detection material.
In addition, about the thickness (diameter) of a fiber, it is preferable to set it as the value within the range of 10-100 micrometers, for example, and what twisted together the fiber may be used.

The X-ray detection adhesive bandage 50 having an X-ray detection material-containing cloth having a predetermined length provided at a location, wherein the absorption pad 20 is made of a first cloth and a second cloth. Spherical or linear X-ray detection that is entirely or partially covered with a covering 14 made of fibers between two woven or non-woven fabrics 10 (10a, 10b) and arranged at a predetermined interval When the X-ray detection material-containing cloth 18 includes a long object 16 having the material 12 and is cut to a predetermined length, and the X-ray detection material is spherical, the average particle diameter is The value should be within the range of 0.1 to 3 mm. If X-ray detection material is linear, and the average length within a range of 0.3 to 10 mm, it is X-ray detection bandage 50, wherein.
Hereinafter, the bandage 50 for X-ray detection of 2nd Embodiment is demonstrated concretely for every structural requirement.

1. Type of base material (1) The type of base material constituting a part of the adhesive protective member in the adhesive bandage for X-ray detection is not particularly limited. For example, polyurethane film, polyester film, vinyl chloride film, olefin film, Examples of the film include a polycarbonate film, a polysulfone film, a polyphenylene sulfide film, a polyimide film, paper, and a film containing fibers.
Further, the form of the substrate is not particularly limited, and may be, for example, a mesh-like material, a woven fabric or a non-woven fabric.
For example, when a mesh-like material or a non-woven fabric is used as the base material, an adhesive protective member for scabs that is extremely excellent in cushioning and breathability can be configured. On the other hand, when a woven fabric made of polyester fiber or the like is used as the base material, moisture permeability can be kept low, and an adhesive protecting member for peanuts excellent in followability to finger movement can be obtained.

Moreover, since it is easy to obtain excellent usability and the like, the elongation percentage of the base material (based on JIS-L-1096, the same shall apply hereinafter) is preferably set to a value of 120% or more, and is preferably 150 to 500%. A value within the range is more preferable, and a value within the range of 200 to 400% is even more preferable.
However, when using a base material that has a high elongation rate and is difficult to handle, it is preferable to provide a reinforcing release member on the surface of the base material.
The reason for this is that by providing the reinforcing peeling member in this way, it is easy to use and can be easily affixed to a predetermined location, and furthermore, it can also function as a process paper at the time of manufacture. It is.
In addition, the reinforcing peeling member exhibits a function as a reinforcing member in addition to the function as a peeling member, and therefore includes a reinforcing material such as a fiber or an inorganic filler, or is thicker than a normal peeling member, It is preferable to increase the mechanical strength.

(2) Thickness Moreover, it is preferable to make the thickness of a base material into the value within the range of 5-2,000 micrometers.
The reason for this is that when the thickness of the base material is less than 5 μm, the mechanical strength is lowered or the handleability is lowered, so that it may not be suitable for use as an adhesive protection member for scabs. Because there is.
On the other hand, when the thickness of the base material exceeds 2,000 μm, it becomes excessively thick and, conversely, it becomes difficult to handle, and in the case where a part of the adhesive protection member for chewing is constituted, This is because they may be easily peeled off.
Therefore, the thickness of the base material is more preferably set to a value within the range of 10 to 1,000 μm, and further preferably set to a value within the range of 15 to 500 μm.
In addition, when the elongation percentage (based on JIS-L-1096) of the base material is 150% or more and the thickness of the base material is 5 to 15 μm, an excellent usability is easily obtained.

(3) Cushion layer Although not shown, it is preferable to provide a cushion layer made of a nonwoven fabric or the like between the adhesive protection member and the base material.
The reason for this is that by providing the cushion layer as described above, the protection of the affected area is excellent, and a further excellent feeling of use can be obtained. Moreover, it is because a cushion layer can exhibit the shape protection effect at the time of providing an unevenness | corrugation etc. in the surface of the adhesion layer.
In addition, although it is an example as a cushion layer which consists of a nonwoven fabric etc., it is preferable that it is the following aspects.
Type: Urethane resin, polypropylene resin, polyester resin, or vinyl chloride resin Thickness: 10-100 μm
Fabric weight: 10 to 100 g / m ²

(4) Water-repellent treatment layer Although not shown, it is preferable to provide a water-repellent treatment layer (including a sizing layer) on the surface of the substrate.
The reason for this is that, in the water work, the external work, the medical field, and the like, the liquid material can be easily prevented from entering from the outside in the sanitary environment. This is because peeling can be effectively prevented.
Such a water-repellent layer is preferably made of, for example, a fluororesin or a silicone resin, and its thickness is preferably set to a value within the range of 0.01 to 5 μm.

(5) Moisture permeability The moisture permeability of the substrate measured in accordance with JIS Z-0208 is preferably set to a value in the range of 100 to 2000 g / m ² · 24 Hrs.
The reason for this is that by controlling the moisture permeability of the base material in this way, liquid work from the outside can be easily prevented even in the water work, the external work, the medical field, etc. This is because peeling of the adhesive protective member can be effectively prevented.
Therefore, the moisture permeability of the base material, it is more preferably set to a value within the range of 200~1700g / m ² · 24Hrs, still more preferably a value within the range of 400~1400g / m ² · 24Hrs.
However, although some uses are limited, when a non-woven fabric is used as the base material or when a vent hole is provided in the base material or the adhesive layer, the base material measured in accordance with JIS Z-0208 The moisture permeability is preferably set to a value of 1500 g / m ² · 24 Hrs or more.

(6) Identification mark and decoration layer Although not shown, it is preferable that an identification mark and a decoration layer are provided on the surface of the substrate.
The reason for this is that by providing a number mark, kanji mark, pictogram mark, braille mark, etc., the adhesive protective member of the optimum size can be clearly identified and the usability when using the adhesive protective member is remarkably improved. Because it can.
In addition, by providing a decorative layer that represents a number pattern, kanji pattern, pictogram pattern, photographic pattern, etc. as such a decorative layer, not only the ease of use when using an adhesive protective member is improved, but also about fashionability It is because the value of can also be improved. In particular, by using a decorative layer containing a fluorescent agent, it is possible to enhance nighttime recognition.

(7) Metal Particles Further, as shown in FIGS. 4A to 4B, it is preferable that the metal material 54 is contained in the base material 56 constituting the base material 58 in the adhesive protection member 60.
The reason for this is that by containing the metal particles in this manner, the interaction between the X-ray detection material in the absorption pad and the metal particles in the substrate can be exhibited. That is, the sensitivity of the metal detector and the X-ray detector can be further improved with respect to the adhesive bandage for X-ray detection provided with such an absorption pad and an adhesive protective member.
In addition, by containing metal particles in this way, even if only the base material in the adhesive protection member is mixed in food or the like, it may be detected depending on the detection conditions of the metal detector or the X-ray detector. This is because it can be done.

Further, the type of the metal particles is not particularly limited. For example, at least one selected from the group consisting of iron, stainless steel, aluminum, copper, silver, solder (including lead-free solder), and nickel. A metal species is preferred.
The reason for this is that it is possible to stably increase the sensitivity of the base material to the X-ray detector and the metal detector, and to provide a relatively inexpensive base material or adhesive bandage. This is because it can.
However, it is more preferable to use iron particles because the sensitivity to X-ray detectors and metal detectors is high and the cost is low.
On the other hand, it is also preferable to use aluminum particles because they are lighter, easier to disperse, have a relatively high sensitivity to X-ray detectors and metal detectors, and are inexpensive.
In addition, about the metal particle contained in a base material, the same kind as the metal included in a predetermined long thing may be sufficient, but by making it a different kind, as a whole adhesive bandage, sensitivity to an X-ray detector or a metal detector. Can be increased more stably.

Moreover, it is preferable to make the average particle diameter of this metal particle into the value within the range of 0.5-30 micrometers.
This is because, when the average particle diameter of the metal particles is less than 0.5 μm, the metal particles are easily aggregated, and the sensitivity to the X-ray detector and the metal detector may be significantly reduced. On the other hand, if the average particle size of the metal particles exceeds 30 μm, it may be extremely difficult to uniformly disperse in the base material, or the flexibility and elongation of the base material may be significantly reduced. is there.
Therefore, the average particle diameter of the metal particles is more preferably set to a value within the range of 3 to 25 μm, and further preferably set to a value within the range of 5 to 20 μm.

Moreover, it is preferable to make the addition amount of this metal particle into the value within the range of 0.1-30 weight%, when the whole quantity of a base material is 100 weight%.
This is because when the amount of the metal particles added is less than 0.1% by weight, the sensitivity to an X-ray detector or a metal detector may be significantly reduced. On the other hand, when the added amount of the metal particles exceeds 30% by weight, it may be extremely difficult to uniformly disperse in the substrate.
Therefore, when the total amount of the metal particles is 100% by weight, the addition amount of the metal particles is more preferably 1 to 20% by weight, and more preferably 3 to 15% by weight. More preferably, it is a value.

2. Type of pressure-sensitive adhesive layer (1) The type of pressure-sensitive adhesive constituting the pressure-sensitive adhesive layer is not particularly limited. For example, an organopolysiloxane pressure-sensitive pressure-sensitive adhesive described below or an acrylic pressure-sensitive adhesive may be used. preferable.

First, in the present invention, it is preferable to use an organopolysiloxane pressure sensitive adhesive as a main component in the adhesive layer.
The reason for this is that, by using an organopolysiloxane pressure-sensitive adhesive, it can exhibit moderate adhesion to the skin, while improving creep resistance, water resistance, and chemical resistance. It is because it can do.
As a typical example of such an organopolysiloxane pressure sensitive adhesive, for example, a silicone resin having a structure represented by general formula (1) or general formula (2) is blended and dehydrated and condensed. Organopolysiloxane and the like are preferable.

(In General Formula (1), R ¹ and R ² are each a methyl group or a phenyl group, and n is an integer of 10 to 10,000.)

(In general formula (2), m represents an integer of 10 to 10,000.)

In the general formula (1), R ¹ and R ² are each a methyl group or a phenyl group, but in order to impart heat resistance to the adhesive layer, the molar ratio of the methyl group to the phenyl group (methyl group) / Phenyl group) is preferably set to a value within the range of 25/75 to 98/2, and more preferably set to a value within the range of 85/15 to 95/5.
Furthermore, in the general formula (1) and the general formula (2), n and m are usually set so that the pressure-sensitive adhesive has a viscosity of 2000 to 200000 cP (in consideration of workability for forming an adhesive layer on a fabric). It is preferable to adjust the numerical value so as to be 25 ° C.

In addition, it is added to the organopolysiloxane pressure-sensitive adhesive (10 to 30% by weight of the total amount), or independently of the organopolysiloxane pressure-sensitive adhesive (100% by weight of the total amount), and acrylic. It is preferable to use an adhesive.
This is because by using such an acrylic pressure-sensitive adhesive, tackiness can be easily improved without reducing the cohesive force of the pressure-sensitive adhesive.
Here, typical examples of such acrylic pressure-sensitive adhesives include acrylic copolymers mainly composed of 2-ethylhexyl acrylate and butyl acrylate.
Further, the blending ratio of such 2-ethylhexyl acrylate and butyl acrylate is adjusted to be 20:80 to 80:20, preferably 20:80 to 40:60, by weight. This is because when the proportion of 2-ethylhexyl acrylate is excessively small, the cohesive force of the adhesive increases and the adhesive strength may decrease. On the other hand, when the proportion of 2-ethylhexyl acrylate is excessively large, the cohesive force of the pressure-sensitive adhesive tends to be too low and the pressure-sensitive adhesive force tends to decrease.
In addition, you may mix | blend acrylamide and vinyl carboxylic acid as a monomer component which comprises an acrylic adhesive in the range which does not exceed 5 weight% with respect to the whole quantity.
Furthermore, considering the compatibility with the organopolysiloxane pressure-sensitive adhesive, the viscosity of the acrylic pressure-sensitive adhesive is preferably set to a value within the range of 500 to 20000 cP (25 ° C.).

(2) Additive In addition, a preparation (drug) can be added as a kind of additive in the pressure-sensitive adhesive composition so as to exhibit a predetermined medicinal effect. The type of such a preparation is not particularly limited, but examples include anti-inflammatory drugs, anti-inflammatory analgesics, coronary vasodilators, asthma drugs, antihypertensive drugs, antihistamines, tranquilizers, antibiotics, anesthetics, One type of vitamin agent or the like, or a combination of two or more types may be mentioned.
Moreover, although the addition amount of a formulation changes with kinds of formulation and the use of an adhesive composition, it shall be set as the value within the range of 0.1-30 mass% with respect to the whole quantity of an adhesive composition, for example. Is preferred.
Moreover, it is preferable to add various additives in an adhesive composition. Examples include antioxidants, viscosity modifiers, ultraviolet absorbers, masking agents, plasticizers, waxes, colorants, inorganic fillers, organic fillers, extenders, coupling agents and the like alone or in combination of two or more. .

(3) Peeling adhesive strength Moreover, the peeling adhesive strength (mode: T mode peeling, adherend: stainless steel plate, peeling speed: 300 mm / min) of the adhesive bandage according to JIS Z0237 is a value within the range of 3 to 20 N / 25 mm. It is preferable that
The reason for this is that when the peel adhesive strength is less than 3 N / 25 mm, it peels easily from the skin or the like, and may have a poor function as a bandage. On the other hand, if the peel adhesive strength exceeds 20 N / 25 mm, it may be difficult to remove the adhesive from the skin, or the skin irritation may become excessively high, resulting in discomfort during use. Because there is.
Therefore, it is more preferable to set the peel adhesive strength of the adhesive bandage to a value within the range of 5 to 15 N / 25 mm, and even more preferable to set the value within the range of 9 to 12 N / 25 mm.
The peel adhesive strength of the adhesive bandage can be adjusted by appropriately selecting the type and thickness of the pressure-sensitive adhesive that constitutes the pressure-sensitive adhesive layer. Hereinafter, although it is an example, when adjusting the peeling adhesive force of adhesive bandage, the aspect of a suitable adhesion layer is shown.
Type: Organopolysiloxane adhesive Thickness: 10-100 μm

[Examples 2 to 5]
In Examples 2 to 5, it was carried out except that the average length of the wire-shaped X-ray detection material included in the long object was 2.5, 3.0, 3.5, and 4.0 mm, respectively. As in Example 1, an adhesive bandage for X-ray detection was prepared and evaluated.

[Comparative Example 1]
In Comparative Example 1, an adhesive bandage for X-ray detection was prepared and evaluated in the same manner as in Example 1 except that a long object not including the X-ray detection material was used.

[Comparative Example 2]
In Comparative Example 2, a long object including an iron wire was not used, and only an iron wire (length: 4 mm, diameter: 1 mm) was disposed between nonwoven fabrics with tweezers, as in Example 1, An adhesive bandage for X-ray detection was prepared and evaluated.
Note that most of the adhesive bandage of Comparative Example 2 could not be produced or used because the iron wire fell out of the absorbent pad during production or use.

[Comparative Example 3]
In Comparative Example 3, an adhesive bandage in which an aluminum film having a length of 25 mm, a width of 13 mm, and a thickness of 100 μm was laminated between a base material and a pad in accordance with the adhesive bandage as shown in FIG. 6 was carried out. Evaluation was performed in the same manner as in Example 1.

As shown in Table 1, the adhesive bandages of Examples 1 to 5 have high sensitivity, X-ray detectability (Evaluation 1) and metal detectability (Evaluation 2 and 3), and usability (Evaluation 4). ) And a foreign object feeling (evaluation 5). In addition, the adhesive bandage of Examples 1-5 was detectable not only with an X-ray detector but with a metal detector.
On the other hand, the adhesive bandage of Comparative Example 1 had good results in terms of metal detectability, usability, and foreign object feeling, but X-ray detectability was extremely low.
Among the adhesive bandages (100) obtained under the conditions of Comparative Example 2, for the adhesive bandages (about 1/3 of the total number) in which the iron wire is contained in the absorbent pad, the X-ray detector and metal detection of the adhesive bandages themselves The sensitivity to the vessel was very good. However, in most of the obtained bandages (about 2/3 of the total number), at the time of manufacturing or testing, the iron wire falls off the absorbent pad, and the sensitivity of the bandages themselves to the X-ray detector and the metal detector is It was very low. That is, the adhesive bandage of Comparative Example 2 was evaluated as having extremely low X-ray detectability and metal detectability (evaluation 2) per 100 adhesive bandages due to the ratio of the presence or absence of iron wires.
In addition, the adhesive bandage from which the iron wire has fallen cannot be subjected to the tests of evaluations 3 to 4, and even when the iron wire is held, the shape of the pad has greatly changed by the iron wire. Slightly difficult to wrap around the finger. Furthermore, since the iron wire is easy to move within the pad, a foreign object sensation was also felt remarkably when applied to a finger.
Although the adhesive bandage of Comparative Example 3 had good metal detectability, the X-ray detectability was extremely low sensitivity. Furthermore, it was slightly difficult to wrap around the finger due to the elastic force of the aluminum film, and a slight foreign body sensation was felt.

[Examples 6 to 10, Comparative Examples 4 to 6]
In Examples 6 to 10 and Comparative Examples 4 to 6, as a base material, a 30 μm-thick urethane film not containing metal particles (elongation rate (based on JIS-L-1096): 450%, moisture permeability (JIS Z-) 0208 compliant): 720 g / (m ² · 24Hrs)) was used, and an adhesive bandage for X-ray detection was prepared and evaluated in the same manner as in Examples 1 to 5 and Comparative Examples 1 to 3. The obtained results are shown in Table 2.

As shown in Table 2, since the adhesive bandages of Examples 6 to 10 and Comparative Examples 4 to 6 do not contain iron particles in the base material, the metal detectability (evaluation 3) with respect to the base material portion is remarkable. It was low.
However, the adhesive bandages of Examples 6 to 10 have good X-ray detectability (Evaluation 1) and metal detectability (Evaluation 2), and are also good in terms of usability (Evaluation 4) and foreign object feeling (Evaluation 5). It was a result.
On the other hand, the adhesive bandage of Comparative Example 4 had good results in terms of usability and foreign material feeling, but X-ray detectability and metal detectability were extremely low.
Moreover, as for the adhesive bandage of Comparative Example 5, as with the adhesive bandage of Comparative Example 2, most of the iron wire has fallen (about 2/3 of the total number), and the adhesive bandage holding the iron wire is About 1/3 of the total. And, due to the ratio of the presence or absence of iron wire in the adhesive bandage, the X-ray detectability (evaluation 1) and metal detectability (evaluation 2) per 100 X-ray detection adhesive bandages were extremely low. Moreover, for the same reason as the adhesive bandage of Comparative Example 2, when holding an iron wire, such an adhesive bandage was slightly difficult to wrap around a finger, and a foreign object feeling was felt remarkably.
In the adhesive bandage of Comparative Example 6, although the metal detectability was good, the X-ray detectability was extremely low sensitivity. Furthermore, it was slightly difficult to wrap around the finger due to the elastic force of the aluminum film, and a slight foreign body sensation was felt.

According to the X-ray detection material-containing fabric in the first reference embodiment of the present invention, it is possible to detect with high sensitivity by an X-ray detector as shown in FIG. As such, it is expected to be used for textile products, clothing, accessory product markers, document markers, electrical product markers, footwear tags, machinery tags, and the like, which have problems in performance.
Moreover, according to the adhesive bandage for X-ray detection of this invention, the absorption pad contains the X-ray detection material containing fabric which arrange | positions the elongate object which contains an X-ray detection material with a predetermined space | interval in a cloth by the coating. In addition to being easy to use, the X-ray detector as shown in FIG. 8 enables detection with high sensitivity.
Therefore, even if the X-ray detection adhesive bandage is mistakenly mixed into a metal package product or the like, it can be detected by the X-ray detector and foreign matter can be easily prevented.
