Description

Disposable wear

The present invention relates to a disposable wear, and more particularly to a disposable wear worn so that the inner surface is adjacent to the wearer's skin.

Conventionally, various kinds of disposable wear have been proposed.

For example, in the glove 101 shown in FIG. 10A which is a perspective view of FIG. 10A and a cross-sectional view taken along line B1-B1 of FIG. (For example, refer to Patent Document 1).

JP 2005-179858 A

¡Gloves-shaped disposable items may be worn for the treatment and prevention of eczema, rashes, cracks, and scratches on the hands.

In such applications, disposable wear with appropriately adjusted breathability is required so that the skin does not dry during wearing and is kept at a suitable humidity level so as not to get steamed. Moreover, even if it wears for a long time, such as sleeping, it is desired that it does not adhere to skin, does not give a sticky feeling, and has a comfortable touch.

In addition, when a coating agent such as petrolatum, cream or ointment is applied to the skin, the disposable wear adheres to the skin due to the adhesion of the coating, and the coating agent adheres to the inner surface of the disposable wear and is removed from the skin. As a result, the effect of the coating agent is reduced. Therefore, it is preferable that the coating agent be removed less.

However, with non-woven fabric alone, it is difficult to ensure strength if the air permeability is appropriately adjusted. Moreover, since a nonwoven fabric contains a fiber, the fluff of a fiber generates an itching and it is not easy to make it comfortable. Furthermore, since the nonwoven fabric is extremely adhered to the skin by the coating agent, the fibers easily wipe the coating agent and remove the coating agent from the skin.

In view of such circumstances, the present invention can adjust the breathability so as to be maintained at an appropriate humidity, can make the skin feel comfortable, and can be used for disposable wearing that can suppress the removal of the coating agent from the wearer's skin. It is intended to provide things.

In order to solve the above-mentioned problems, the present invention provides a disposable wear configured as follows.

Disposable wear is worn so that the inner surface is adjacent to the wearer's skin. The disposable wear includes a composite layer. The composite layer has (a) a first layer having first and second main surfaces, a first layer in which a through-hole penetrating between the main surfaces is formed, and (b) a pair of main surfaces, A second layer that is air permeable between the major surfaces, formed of a hydrophobic material, and joined to the second major surface of the first layer. The first main surface is hydrophobic and is worn in a state where the first main surface is adjacent to the wearer's skin.

In the above configuration, when a disposable article is worn, moisture (water vapor) evaporated from the skin enters the through hole space from one end of the through hole of the first layer and is held in the through hole space. . Since the second layer adjacent to the other end of the through hole can be ventilated, the air permeability can be adjusted so that the space of the through hole is maintained at an appropriate humidity. In other words, by adjusting the air permeability, it is possible to prevent the skin from drying due to excessive ventilation and the stuffiness due to insufficient ventilation and keep the skin moist.

Since the first main surface of the first layer adjacent to the wearer's skin has hydrophobicity, it has excellent affinity with the coating agent and has low surface tension and can be easily peeled off from the skin. Therefore, by adjusting the shape, size, distribution, etc. of the through holes formed in the first layer, the first main surface of the first layer does not adhere to the skin of the wearer, does not give a sticky feeling, It can be formed to have a comfortable touch.

Furthermore, when an oil-based coating agent such as cream or ointment is applied to the skin of the wearer, the first principal surface of the first layer has a reduced surface area due to the opening of the through hole. Is less adhered to the first main surface of the first layer. As a result, it can suppress that an application agent is removed from a wearer's skin.

Preferably, the first main surface of the first layer has a contact angle with a physiological saline of 85 degrees or more. In this case, the 1st main surface of the 1st layer exhibits moderate hydrophobicity.

Preferably, the first layer is formed using a polyolefin resin sheet material having a contact angle with physiological saline of 85 degrees or more.

Preferably, the sheet material forming the first layer is made of a low density polyethylene resin.

Preferably, the area of the first opening formed in the first main surface of the first layer by the through hole is the first area formed in the second main surface of the first layer by the through hole. It is larger than the area of the two openings. Each of the first openings has an area corresponding to a circle having a diameter of 280 to 1400 μm. The distribution density of the first openings in the first main surface is 50 to 400 / cm ² . In this case, the contact angle of the first main surface can be adjusted by forming the through hole.

Preferably, the second layer is formed of a microporous film, woven fabric, knitted fabric or non-woven fabric.

The composite layer has an air permeability measured in accordance with JIS L 1096 of 5 to 2000 cm ³ / cm ² · S, and the water repellency on the first layer side measured in accordance with JIS L 1092 is 3 or more.

Preferably, the second layer is formed by using a polyolefin resin, a JIS L air permeability measured according 1096 ^{^{5 ~ 2000cm 3 / cm 2 ·}} S, water repellency is measured according to JIS L 1092 Is grade 3 or higher.

Preferably, the second layer is formed using a nonwoven fabric made of polypropylene fibers.

In a preferred aspect, the composite layer in which the second layer is bonded to the second main surface of the first layer is configured such that the first main surfaces of the first layer of the composite layer face each other. Are superimposed on each other or folded in half.

In another preferred embodiment, the disposable wear is formed in a bag shape having an opening at one end when worn, and the first main surface of the first layer forms the inner surface. In this case, the disposable wear can be worn by forming it into a bag-like shape such as gloves or socks. In addition, it is not necessary to form in the bag shape which has an opening in one end by folding etc. except at the time of wearing. Moreover, it does not matter whether the other end has an opening or not.

In another preferred embodiment, the disposable wear is formed in a bowl shape when worn, and the first main surface of the first layer forms the inner surface. In this case, the disposable wear can be worn by forming it in a shape that covers the face, wrinkles and the like. In addition, it does not need to be formed in a bowl shape by being folded except at the time of wearing.

In another preferred embodiment, the sleeve is formed in a cylindrical shape having openings at both ends when worn, and the first main surface of the first layer forms the inner surface. In this case, the disposable wear can be worn by forming it in a shape that covers the knees, elbows and the like. In addition, it does not need to be formed in the cylindrical shape which has an opening in both ends by folding etc. except at the time of wear.

Hereinafter, embodiments of the present invention will be described with reference to FIGS.

<Example 1> The disposable wear 10 of Example 1 will be described with reference to FIGS.

FIG. 1 is a plan view of the disposable wear 10. FIG. 2 is a cross-sectional view taken along line XX in FIG. FIG. 3 is a cross-sectional view when the disposable wearable article 10 is worn.

As shown in FIG. 1, the disposable wear 10 is formed in a glove shape. Specifically, as shown in FIGS. 1 and 2, the first and second

composite layers

11a and 11b formed in the shape of a hand are joined to each other along the outer peripheral edge except for the wrist portion. 10x is formed. Note that instead of joining two composite layers on top of each other, one composite layer may be folded and joined to form a glove shape. When worn, it is formed into a bag shape having an opening at one end. In addition, it is not necessary to form in the bag shape which has an opening in one end by folding etc. except at the time of wearing. Moreover, it does not matter if the finger part at the other end has an opening or not.

In the inner portion 10y surrounded by the joint portion 10x, the first and second

composite layers

11a and 11b facing each other are not joined. When wearing the disposable article 10, as shown in FIG. 3, the hand 2 is put between the

composite layers

11a and 11b of the inner part 10y.

As shown in FIG. 2 and FIG. 3, the first layer 12 and the second layer 14 are joined to the

composite layers

11a and 11b.

The first layer 12 has first

main surfaces

12p and 12s and second

main surfaces

12q and 12t. The first and second

composite layers

11a and 11b are bonded to each other at the bonding portion 10x in a state where the first

main surfaces

12p and 12s of the first layers 12 are overlapped with each other. As shown in FIG. 3, the first

main surfaces

12p and 12s of the first layer 12 are adjacent to the skin of the wearer's hand 2 in the inner portion 10y.

The second layer 14 is joined to the second

main surfaces

12q and 12t of the first layer 12. The second layer 14 has a pair of main surfaces 14p, 14q; 14s, 14t. The second layer 14 can be ventilated between the main surfaces 14p, 14q; 14s, 14t. The second layer 14 is made of a hydrophobic material.

As the first layer 12, as shown in FIG. 4B, it is preferable to use a perforated film in which a large number of through holes 12x are formed in a resin film. 1 to 3, the illustration of the through hole 12x is omitted.

FIG. 4A is an enlarged cross-sectional view of the

composite layers

11a and 11b. FIG. 4B is an enlarged perspective view of the first layer 12. As shown in FIG. 4, the first layer 12 is formed with a large number of through holes 12x penetrating between the

main surfaces

12p, 12q; 12s, 12t. Through holes 12x, first openings 12m are formed in the first

main surfaces

12p, 12s of the first layer 12, and second openings 12n are formed in the second

main surfaces

12q, 12t of the first layer 12. It is formed.

The through hole 12x is an inclined hole that is formed in a substantially truncated cone shape and has a tapered shape in which the cross section gradually decreases from the first opening 12m toward the second opening 12n. The area of the first opening 12m is larger than the area of the second opening 12n. In order to realize appropriate air permeability and comfortable touch, for example, the first opening 12m is preferably formed to have an area corresponding to a circle having a diameter of 280 to 1400 μm. The distribution density of the first openings 12m in the first

main surfaces

12p and 12s is preferably 50 to 400 pieces / cm ² .

In addition, the through-hole formed in the 1st layer 12 can be made into arbitrary shapes, such as a barrel shape and a drum shape where a cross section increases / decreases from the 1st opening 12m toward the 2nd opening 12n.

Since the concavo-convex shape is formed on the second

main surfaces

12q and 12t side of the first layer 12, moisture (vapor) evaporated from the skin is retained, so that the moisture retaining effect of maintaining humidity is enhanced. But it is also possible to make the 2nd

main surface

12q and 12t side of the 1st layer 12 into a plane. Even in that case, the vapor is retained in the through hole.

In the first layer 12, at least the first

main surfaces

12p and 12s are hydrophobic. Specifically, the first

main surfaces

12p and 12s of the first layer 12 are preferably formed so that the contact angle with the physiological saline is 85 degrees or more.

The contact angle is a value measured by the θ / 2 method according to JIS K2396. For example, measurement is performed as follows. First, a sample sheet material is cut into a square of 1.5 to 2 cm, and placed at a measurement site of a contact angle measurement device (trade name: FTA-100, manufactured by First Ten Ten Angstrom). Next, 1.5 μL of the standard droplet reference sample is brought into contact with the sample piece from the syringe installed in the contact angle measurement device, and each dynamic contact angle after 1, 3, 5, and 10 minutes is measured by the droplet method. (Droplet supply speed: 0.5 μL / second, drop amount: 1.5 μL), and analyzed by a contact angle measuring device.

The first layer 12 is preferably a resin having a contact angle with physiological saline of 85 degrees or more, such as a polyolefin resin, a silicone resin, a polytetrafluoroethylene resin, a polyurethane resin, or a polypropylene resin.

In addition, polyolefin resin (for example, polyethylene resin) having a contact angle with physiological saline of less than 85 degrees, polyamide resin such as nylon 6 and nylon 66, polystyrene resin (contact angle with physiological saline: 84 degrees), etc. Even so, it is only necessary to form a through-hole or the like to exhibit hydrophobicity with a contact angle of 85 degrees or more. That is, the first layer 12 is more preferably a polyolefin resin-made perforated film having a contact angle with physiological saline of 85 ° or more, and particularly preferably a polyethylene resin-made perforated film capable of obtaining appropriate flexibility.

In this case, a high-density polyethylene resin (density range: 930 to 970 kg / m ³ ) or a low-density polyethylene resin (density range: 910 to 930 kg / m ³ ) is preferably used, and among them, a low-density polyethylene resin is particularly preferable. This is because the contact angle of the low density polyethylene resin itself is 82 °, but a desired contact angle (for example, 110 °) can be obtained by forming the through hole.

The

composite layers

11a and 11b in which the first layer 12 and the second layer 14 are joined are formed to have appropriate air permeability and water repellency.

The air permeability between the main surfaces 12p, 14q; 12s, 14t of the

composite layers

11a, 11b is preferably 5 to 2000 cm ³ / cm ² · S. This air permeability is measured using a Frazier type fiber air permeability tester based on Method A (Fragile method) described in JIS L 1096. Specifically, after attaching a test piece to the Frazier type tester, the suction fan is adjusted by an adjustable resistor so that the inclined barometer exhibits a pressure of 125 Pa, and the pressure indicated by the vertical barometer at that time The air permeability is measured by determining the amount of air [cm ³ / cm ² · S] passing through the test piece from the type of air hole used, using the table attached to the tester. The air permeability is obtained by an arithmetic average of five measurement values.

The water repellency on the first layer 12 side of the

composite layers

11a and 11b is preferably 3 or more. This water repellency is based on the water repellency test (spray test) described in JIS L 1092. The water repellency test is equipped with a spray nozzle having a predetermined capacity (capability to spray 250 mL of water in 25 to 30 seconds). It is measured using a device. Specifically, (1) a test piece of about 20 cm × 20 cm is attached to the test piece holding frame of the water repellency test apparatus, and 250 mL of water is applied to the test piece (on the first layer) by the spray nozzle for a required time 25 (2) Remove the holding frame from the top of the water repellency test device, perform the specified operation to drop excess water droplets on the test piece, and (3) attach it to the holding frame. The water repellent degree is measured by scoring the wet state of the obtained test piece in comparison with a comparative sample in a predetermined wet state. The predetermined operation in (2) means that the test piece is held in a state where one end of the holding frame is held horizontally, the front side of the test piece faces downward and the other end of the holding frame is lightly applied to a hard object. This is an operation of rotating 180 degrees. The temperature during the water repellency test is set to 20 ± 2 degrees Celsius, and the water used for the measurement is distilled water or ion exchange water.

The second layer 14 can be formed using a breathable hydrophobic material, for example, a microporous film, a woven fabric, a knitted fabric, or a non-woven fabric. The second layer 14 is formed to have an appropriate air permeability and water repellency.

The air permeability between the main surfaces 14p, 14q; 14s, 14t of the second layer 14 is preferably 5 to 2000 cm ³ / cm ² · S. This air permeability is measured using a Frazier type fiber air permeability tester based on Method A (Fragile method) described in JIS L 1096. Specifically, after attaching a test piece to the Frazier type tester, the suction fan is adjusted by an adjustable resistor so that the inclined barometer exhibits a pressure of 125 Pa, and the pressure indicated by the vertical barometer at that time The air permeability is measured by determining the amount of air [cm ³ / cm ² · S] passing through the test piece from the type of air hole used, using the table attached to the tester. The air permeability is obtained by an arithmetic average of five measurement values.

The water repellency of the second layer 14 is preferably 3 or higher. This water repellency is based on the water repellency test (spray test) described in JIS L 1092. The water repellency test is equipped with a spray nozzle having a predetermined capacity (capability to spray 250 mL of water in 25 to 30 seconds). It is measured using a device. Specifically, (1) A test piece of about 20 cm × 20 cm is attached to the test piece holding frame of the water repellency test apparatus, and 250 mL of water is sprayed on the test piece by the spray nozzle in a required time of 25 to 30 seconds. (2) Remove the holding frame from the surface of the water repellency test apparatus, perform a predetermined operation to drop excess water droplets on the test piece, and (3) wet the test piece attached to the holding frame. The water repellency is measured by scoring the measured state against a comparative sample in a predetermined wet state. The predetermined operation in (2) means that the test piece is held in a state where one end of the holding frame is held horizontally, the front side of the test piece faces downward and the other end of the holding frame is lightly applied to a hard object. This is an operation of rotating 180 degrees. The temperature during the water repellency test is set to 20 ± 2 degrees Celsius, and the water used for the measurement is distilled water or ion exchange water.

The second layer 14 can be formed using a sheet material. For example, hydrophobicity such as polyolefin resin (eg, polypropylene, polyethylene, etc.), polyester resin (eg, polyethylene terephthalate, polybutylene terephthalate, polypropylene terephthalate, etc.), polyamide resin (eg, nylon 6, nylon 66, etc.), polyurethane resin, etc. A sheet material such as a nonwoven fabric, a microporous film, or a woven or knitted fabric made of a material can be used. Among these, a nonwoven fabric is preferable, a nonwoven fabric composed of polyolefin fibers is more preferable, and a nonwoven fabric composed of polypropylene fibers is particularly preferable.

The nonwoven fabric that can be used for the second layer 14 is not limited to a specific type, and various wet nonwoven fabrics and dry nonwoven fabrics can be used. For example, a thermal bond nonwoven fabric, a needle punched nonwoven fabric, a spunlace nonwoven fabric, a spunbond nonwoven fabric, A melt blown nonwoven fabric, a flash spinning nonwoven fabric, or a composite type of these nonwoven fabrics may be used. Examples of the composite type nonwoven fabric include so-called SMS nonwoven fabric and SMMS nonwoven fabric, in which a melt blown nonwoven fabric and a spunbond nonwoven fabric are combined. These non-woven fabrics are not limited to those formed from hydrophobic synthetic fibers, and for example, non-woven fabrics formed from hydrophilic fibers such as cotton and rayon and subjected to water repellent treatment may be used.

The nonwoven fabric used for the second layer 14 is particularly preferably a nonwoven fabric obtained by a melt blow method or a nonwoven fabric obtained by a flash spinning method. Since melt blown nonwoven fabric and flash spinning nonwoven fabric are composed of ultrafine fibers having a fiber diameter of about 20 μm or less, for example, the basis weight (basis weight) is higher than nonwoven fabrics obtained by other manufacturing methods such as the spunbond method. Even if it is the same, the space | gap produced between fibers can be made small. As a result, moisture retention is improved.

Briefly, melt blown non-woven fabric is obtained by blowing high-temperature and high-pressure air at the outlet of a spinning nozzle and drawing and defibrating the fiber, and is composed of continuous ultrafine fibers. Yes. The melt blown nonwoven fabric may be used for the second layer 14 as the SMS nonwoven fabric, the SMMS nonwoven fabric, or the like that is laminated in combination with the spunbond nonwoven fabric.

The flash-spun non-woven fabric is a solution in which a fiber-forming polymer is uniformly dissolved in a low-boiling solvent at high temperature and high pressure, and then the solution is discharged from a nozzle to rapidly gasify and expand only the solvent. This is a net-like non-woven fabric made of ultrafine fibers, which is obtained by solidifying while stretching the fiber-forming polymer.

The nonwoven fabric used for the second layer 14 may be calendered. This calendering refers to a process of pressurizing a nonwoven fabric using a calender roll or an embossing roll adjusted to a temperature below the melting point. By calendering, some of the fibers constituting the nonwoven fabric are heat-sealed, and voids formed between the fibers are crushed, and the shape is moderately maintained and the touch is improved. Further, for example, a dot pattern can be formed by calendering to improve the appearance.

Next, an example of producing the disposable wear 10 will be described.

For the first layer 12, a mesh sheet material in which a large number of through holes were formed in a polyethylene sheet material was used. In the mesh sheet material, the distance (thickness) between the first opening on the first main surface side and the second opening on the second main surface side was set to 480 μm. The opening diameter on the first main surface side is 615 μm, and the through hole 12x of the inclined hole whose opening diameter on the first main surface side is about 1.25 times the opening diameter on the second main surface side is formed. . The through-holes 12x are formed at a density of 200 / cm ² , and the aperture ratio, that is, the openings formed by the through-holes in the entire mesh sheet material, that is, the second main surface where the smaller second opening is formed. The area ratio was about 40%.

For the second layer 14, a nonwoven fabric made of polypropylene fibers is used.

A synthetic rubber-based hot melt adhesive is applied to the portion corresponding to the second

main surfaces

12q and 12t side of the first layer 12 of the mesh sheet material so as not to impair air permeability as much as possible. The polypropylene nonwoven fabric for forming is joined, and the composite sheet for forming the

composite layers

11a and 11b is formed.

The two composite sheets are heat-sealed along the outer shape of the hand shape with the mesh sheet material facing each other and facing each other, and welded and cut to form the joint 10x. A disposable disposable article 10 was formed.

As long as the joint 10x can be formed, in addition to heat sealing, the joint 10x may be formed by welding with a sonic seal, bonding with a hot melt adhesive, or the like.

In the disposable article 10 configured as described above, moisture (water vapor) evaporated from the skin when worn enters the space of the through hole 12 from one end of the through hole 12x of the first layer 12, and the through hole 12x. Is held in the space. Since the second layer 14 adjacent to the other end of the through hole 12x can be ventilated, the air permeability can be adjusted so that the space of the through hole 12x is maintained at an appropriate humidity. That is, by selecting the size, shape and distribution density of the through-holes 12x formed in the first layer 12, the air permeability of the second layer 14, etc., the air permeability is adjusted, and the skin is dried due to excessive ventilation or the ventilation Prevents dampness due to lack and keeps the skin moist.

Since the first

main surface

12p, 12s of the first layer 12 adjacent to the wearer's skin has hydrophobicity, it has excellent affinity with the coating agent, and has low surface tension, and can be easily peeled off from the skin. it can. Therefore, by adjusting the shape, size, distribution, etc. of the through holes 12x formed in the first layer 12, the first

main surfaces

12p, 12s of the first layer 12 do not adhere to the wearer's skin, It can be formed to give a comfortable touch without giving a sticky feeling.

Further, when an application agent such as cream or ointment is applied to the skin of the wearer, the first

main surface

12p, 12s of the first layer 12 has a reduced surface area due to the

openings

12m, 12n of the through holes 12x. Yes. The amount of the coating agent adhering to the first

main surfaces

12p and 12s of the first layer 12 is reduced as compared with the case where no through hole is formed. As a result, it can suppress that an application agent is removed from a wearer's skin.

Since the second layer 14 is formed of a hydrophobic material, it has hydrophobicity and moisture adhesion is suppressed. By adjusting the water repellency of the second layer 14, it is possible to prevent stuffiness and to keep moisture appropriately.

By using the

composite layers

11a and 11b, the entire inner surface of the disposable wearable article 10 is configured to be substantially uniform, so that the effects such as air permeability, moisture retention, touch, and suppression of removal of the coating agent are substantially uniform over the entire inner surface. Become.

<Example 2> The disposable wear 10k of Example 2 will be described with reference to FIGS.

The disposable wear 10k of Example 2 is configured in substantially the same manner as the disposable wear 10 of Example 1. In the following, the same reference numerals are used for the same components as in the first embodiment, and differences from the first embodiment will be mainly described.

5 and 6 are sectional views similar to FIGS. 2 and 3. As shown in FIG.5 and FIG.6, instead of the 2nd composite layer 11a of the disposable wear thing 10 of Example 1, the one side (upper side in the figure) of the disposable wear thing 10k is the 2nd layer of 1 layer structure. Only 14k is used. The other side (lower side in the figure) of the disposable wear 10k is the first composite layer 11b having the same configuration as the disposable wear 10 of the first embodiment. The second layer 14k and the first composite layer 11b are formed in the shape of a hand, and are joined together along the outer peripheral edge except for the wrist portion to form a joint 10x.

The second layer 14 and the second layer 14k of the first composite layer 11b of the disposable wearable article 10k have the same configuration as that of the first embodiment, and have

main surfaces

14s and 14t; 14u and 14v, respectively. .

In the inner portion 10y surrounded by the joint portion 10x, the second layer 14k and the composite layer 11b are only in contact with each other. When wearing the disposable wear item 10k, as shown in FIG. 6, the hand 2 is put between the inner

main surfaces

14u and 12s of the inner layer 10y facing each other between the second layer 14k and the composite layer 11b. At this time, the inner main surface 14u of the second layer 14k and the main surface 12s of the first layer 12 of the composite layer 11b are adjacent to the wearer's skin.

The disposable wear 10k is moderately moisturized by the composite layer 11b so as to prevent the skin and dryness of the wearer adjacent to the composite layer 11b and keep the skin moist, as in Example 1.

Since the inner main surface 12s of the first layer 12 of the composite layer 11b adjacent to the skin of the wearer has hydrophobicity, the inner main surface 12s of the first layer 12 is excellent in affinity with the coating agent and has a surface tension. Is low and can be easily peeled off from the skin. In addition, a through hole is formed in the first layer 12. Therefore, by adjusting the shape, size, distribution, etc. of the through holes, the inner main surface 12s of the first layer 12 does not adhere to the skin of the wearer, does not give a sticky feeling, and has a comfortable touch. Can be formed.

<Example 4> The disposable clothing 30 of Example 4 will be described with reference to FIG. FIG. 8 is a schematic diagram showing the configuration of the disposable wear 30.

As shown in FIG. 8 (a), in the disposable wearable 30 of Example 4, two substantially half-moon-shaped members that are overlapped are joined by an arc-shaped joining portion 32. At the time of use, as shown in FIG. 8 (b), the two members are expanded to be formed into a bowl-like shape and used in a state of covering the wearer's heel. Except when worn, it may not be formed into a bowl shape by being folded. The state where the disposable wearable item 30 covers the heel is maintained by sticking the disposable wearable item 30 on the foot with a tape or putting on socks from the top of the disposable wearable item 30. The disposable wear 30 is formed using a composite layer having the same configuration as that of the first embodiment, and the inner surface adjacent to the wearer's heel is formed by the first layer.

<Example 5> The disposable wear 40 of Example 4 will be described with reference to FIG.

As shown in FIG. 9, the disposable wear 40 of Example 5 is formed in a cylindrical

shape having openings

42 and 44 at both ends when worn. Except when worn, it may not be formed into a cylindrical shape having openings at both ends, for example, by being folded. The disposable wear 40 is formed using a composite layer having the same configuration as in the first embodiment, and the inner surface 46 is formed by the first layer. The wearer's hands and feet are inserted through the wearable item 40 and used in a state of covering the elbows and knees of the wearer.

<Summary> The

disposable wear items

10, 10k, 20, 30, and 40 of Examples 1 to 5 described above can adjust the breathability so as to be kept at an appropriate humidity, and can have a comfortable touch. It can suppress that an application agent is removed from a wearer's skin.

For example, in the case of atopic dermatitis such as intractable eczema, in order to enhance the effect of steroids, a steroid agent is applied to the affected area and then covered with a plastic film such as a food wrap film (ODT). Law) is known. However, when the affected area to which the steroid agent is applied is covered with a plastic film, the steroid agent is excessively absorbed by the affected area, and the symptoms may worsen. Therefore, by wearing the wear of the present application toward the affected area to which the steroid is applied, the affected area can be cured by an appropriate action of the steroid agent together with the breathability of the wear of the present application.

It should be noted that the present invention is not limited to the above embodiment, and can be implemented with various modifications.

For example, a glove-shaped disposable wear that covers the fingers separately is illustrated, but even if the disposable wear is formed in a mittens shape that covers the thumb and other fingers separately, all fingers are covered together You may form a disposable wear thing in a shape. It may be configured such that a part of the hand such as a fingertip, the entire finger, a part of the palm or the back of the hand, etc. is exposed without a part of the part covering the hand.

限ら Not limited to gloves, it may be formed in a bag-like shape like a sock.
