Description

The present invention relates to textile products for ostomy appliances and ostomy appliances. More specifically, the present invention relates to a textile product for an ostomy appliance for forming an ostomy appliance and an ostomy appliance.

A stoma typified by an artificial anus or an artificial bladder may be constructed on the body due to a disease or the like. Since ostomy cannot self-control the excretion of waste products, it is common for ostomy holders to wear ostomy appliances equipped with bags (ostomy pouches) for storing waste products. As a result, stoma holders can store waste products at any time, which greatly contributes to improving the lives of stoma holders.

On the other hand, it is said that users of ostomy appliances often have a psychological burden because they are worried that the odor of the contained waste products may leak from the ostomy pouch and cause discomfort to the people around them. In fact, a research report that stoma exhaust gas contains four times the concentration of hydrogen sulfide compared to the stool odor of healthy people, and when onions are eaten, the concentration is eight times higher (Kakenhi Project No. 26560073). Research result report) is known. For these reasons, there is a strong demand for a technique for effectively suppressing the leakage of odor from the ostomy appliance. As such a technique, the technique disclosed in Patent Document 1 below is known.

Japanese Unexamined Patent Publication No. 01-299551 International Publication No. 2015/194334 Pamphlet

Waste products excreted from the stoma include not only solid content (excrement) and liquid content (excrement, exudate, secretion, etc.) but also gas (excrement gas). Then, it becomes necessary to let the gas component escape to the outside of the ostomy pouch so that the ostomy pouch is not inflated by the gas component.
In this regard, the ostomy pouch of Patent Document 1 is made of EBA (ethylene butyl acrylate) and has an intermediate wall 30 having about 248,000 puncture holes per square meter. The intermediate wall 30 prevents the filter from coming into contact with liquid or solid waste products, and maintains the filter performance.

However, if the degree of closure of the intermediate wall 30 is increased to prevent contact between the filter and waste products, the air permeability is naturally lowered by that amount, and it becomes difficult for the gas content in the ostomy pouch to escape to the outside. On the other hand, if the degree of closure of the intermediate wall 30 is weakened, there is a contradictory problem that liquid and solid waste products in the ostomy pouch tend to come into contact with the filter.
In this respect, there is a problem that the ostomy pouch having a filter that actually exists on the market does not sufficiently degas and the pouch continues to swell. For this reason, the user has no choice but to open the discharge port several times a day and "vent gas" without using a filter, and the odor at that time becomes a problem. That is, even if a filter is provided to prevent the pouch from swelling excessively due to the gas stored in the ostomy pouch, the structure must be such that liquid does not leak when the pouch is pressed during normal use. From the balance of the above, it is considered that there is also a problem that the air permeability of the filter cannot be sufficiently increased.

Furthermore, the filter may be clogged by contact with liquid or solid waste products stored in the ostomy pouch, which may reduce the filter performance, but the waste products from the stoma in particular contain a large amount of oil and fat. It turns out that this is a problem. For example, in an ileostomy constructed by guiding the ileum to the surface of the body, the absorption of bile acids performed at the terminal portion of the ileum is insufficient, and the waste products may contain a large amount of fat-soluble bile acids. In addition, deficiency of lipid absorption in the ileum is likely to occur, and waste products may contain a large amount of lipids. As described above, it has been found that when the oil and fat contained in the waste product comes into contact with the filter, there is a problem that the filter performance is particularly significantly deteriorated. In this respect, the technique of Patent Document 1 uses carbon-impregnated polyurethane open cell foam as a filter medium. Since the deodorizing mechanism of carbon (activated carbon or the like) is physical adsorption to the pores, there is a problem that the deodorizing ability is particularly significantly reduced due to contact with fats and oils as described above.

Although the technique disclosed in Patent Document 2 is disclosed as a deodorant mask by the present inventor, the focus is on the fact that it can be used for ostomy appliances, the focus on the problem of contact with oils and fats, and further. No study has been made on a configuration that can maintain deodorant performance even by contact with fats and oils.

The present invention has been made in view of the above problems, and an object of the present invention is to provide a textile product for a ostomy appliance capable of exhibiting a high deodorizing power, and a ostomy appliance using the textile product for a ostomy appliance.

[1] Textile products for ostomy appliances The textile products for ostomy appliances (1) of the present invention are for forming ostomy appliances.
The fiber aggregate (11), the deodorant (12) attached to the fibers (111) constituting the fiber aggregate (11), and the binder resin (13) having the deodorant (12) attached to the fibers. ) And.
Further, among these, the deodorant (12) contains an inorganic deodorant containing a metal element.
The binder resin (13) contains a polymer having a solubility parameter (SP value) of 10.0 or more (see FIG. 1).

As used herein, the term "stoma" includes the meaning of an excretory hole that guides the digestive tract and urinary tract to the outside of the body. These stoma are usually built on the abdominal wall of the body. Therefore, in the present invention, the stoma includes a gastrointestinal stoma that guides the gastrointestinal tract to the outside of the body and a urinary tract stoma (urostoma) that guides the urinary tract to the outside of the body. Further, the above-mentioned gastrointestinal stoma includes an ileo stoma that guides the ileum to the outside of the body and a colon stoma (colon stoma) that guides the large intestine to the outside of the body. In addition, the above-mentioned urethral stoma includes an ileal conduit, a ureteral cutaneous fistula, a renal fistula, a bladder fistula and the like. And the ostomy appliance includes the above-mentioned ostomy appliance in general with an opening for receiving the ostomy.

As described above, this textile product for ostomy appliances uses an inorganic deodorant as a deodorant and has a SP value of 10.0 or more (hereinafter, also simply referred to as "hydrophilic polymer"). ) Is used as a binder resin. Therefore, it is possible to exhibit particularly excellent deodorizing performance as a textile product for ostomy appliances. In particular, it has excellent deodorizing properties in the presence of oil (oil and lipophilic components). Similarly, the water system is also excellent in that it can form an effective deodorizing field for the sulfur-based component showing water solubility among the odor components.

Specifically, for example, the waste products discharged from the stoma holder to the stoma pouch contain more oil and lipophilic components (bile acids, etc.) than the waste products (feces, urine, etc.) of the non-stoma holder. Tends to be. For this reason, when a conventional textile product is used as a ventilation filter for a stoma pouch, the oil content tends to adhere to the textile product due to contact with the oil component, which may hinder the air permeability. Further, in textile products containing activated carbon, which is often used as an adsorbent, the activated carbon has a property of easily adsorbing oil, so that the activated carbon may be saturated or blocked by the oil early after use.
In this respect, the textile product for ostomy appliances of the present invention can exhibit excellent deodorizing performance even in the above-mentioned environment. It is considered that this is because an inorganic deodorant is contained as a deodorant and the deodorant is attached to the fiber by a hydrophilic polymer, so that the deodorization inhibition due to the oil content as described above is unlikely to occur. .. Furthermore, in this textile product for ostomy appliances, the deodorant and the binder resin have a high affinity, so that the deodorant can be firmly attached to and fixed to the fiber with a smaller amount of the binder resin, so that the deodorant can be effectively used. It is thought that it is.

(1) Fiber Aggregation The above-mentioned "fiber aggregate" is an aggregate of fibers in which a plurality of fibers are entangled with each other, and has a function of maintaining a deodorant on the fibers while ensuring air permeability. As the fiber aggregate, for example, non-woven fabric, woven fabric, knitted fabric and the like can be used. Only one of these may be used, or two or more thereof may be used in combination. Among these, a non-woven fabric is preferable from the viewpoint that the desired thickness can be easily set, the air permeability can be easily controlled, and the manufacturing cost is low.

Further, the type of the non-woven fabric is not limited, and the non-woven fabric obtained by any manufacturing method may be used. For example, (1) a non-woven fabric obtained by melt spinning, (2) a non-woven fabric obtained by a physical entanglement method, (3) a non-woven fabric obtained by a heat fusion method, and (4) entangled using an adhesive. Non-woven fabric and the like can be mentioned. Among these, examples of the non-woven fabric of (1) include spunbonded non-woven fabrics and melt-blown non-woven fabrics. Examples of the non-woven fabric of (2) include airflow entangled non-woven fabric, water flow entangled non-woven fabric (spun lace), needle punched non-woven fabric and the like. Examples of the non-woven fabric of (3) include a thermal bonded non-woven fabric and an embossed non-woven fabric. Examples of the non-woven fabric of (4) include various chemical-bonded non-woven fabrics. Only one of these may be used, or two or more thereof may be used in combination. Among these, spunbonded non-woven fabric, spunlace non-woven fabric, needle punched non-woven fabric, thermal-bonded non-woven fabric and the like are preferable from the viewpoint of retention and breathability of the deodorant.

The fibers constituting the fiber aggregate are not limited, and examples thereof include organic fibers (resin fibers, plant fibers, etc.), inorganic fibers (glass fibers, carbon fibers, metal fibers, etc.), and composite fibers thereof. Of these, organic fibers are preferred.
Moreover, among the organic fibers, resin fibers are preferable. The resin constituting the resin fiber is not limited, and examples thereof include polyester, polyethylene, polypropylene, polyvinyl chloride, polyacrylic acid, polyamide, polyvinyl alcohol, polyurethane, polyvinyl ester, polymethacrylic acid ester, and rayon. Only one of these may be used, or two or more thereof may be used in combination. Among these, polyester, polyethylene, polypropylene and rayon are preferable, and polyester, polyethylene and polypropylene are more preferable.

Further, as the fiber constituting the fiber aggregate, a hydrophilic resin fiber can be used. Examples of the hydrophilic resin fiber include a resin fiber containing polyvinyl alcohol, a resin fiber containing a hydrophilic polymer into which a hydrophilic group (polar group such as an OH group) has been introduced by modification or the like. Only one of these may be used, or two or more thereof may be used in combination. More specifically, the resin component of the fiber contained in the fiber aggregate may include a hydrophilic polymer having a solubility parameter (SP value) of 10.0 or more. The fiber aggregate containing such hydrophilic resin fibers can be in a moist state by contact with the water contained in the waste products stored in the stoma pouch. In this respect, hydrogen sulfide, which is one of the components having the strongest odor in the waste products, has excellent solubility in water. Therefore, it is excellent in that hydrogen sulfide can be deodorized by being dissolved in the adhering water of the hydrophilic resin fiber, trapped, and then brought into contact with a deodorant.

When the fiber aggregate contains hydrophilic resin fibers, the SP value of the resin component constituting the hydrophilic resin fibers is measured or calculated in the same manner as in the case of the binder resin described later. Further, the SP value (SP ₁ ) of the resin component constituting the hydrophilic resin fiber and the SP value (SP ₂ ) of the resin component constituting the binder resin may be the same or different. If they are different, the values are preferably closer. Specifically, 0 ≦ | SP ₁ −SP ₂ | ≦ 2 is preferable, 0 ≦ | SP ₁ −SP ₂ | ≦ 1 is more preferable, and 0 ≦ | SP ₁ −SP ₂ | <1 is particularly preferable.

Further, when two or more different resin fibers are contained as described above, a high melting point resin fiber made of a resin having a relatively high melting point and a low melting point resin fiber made of a resin having a relatively low melting point are used. The combined fiber aggregate can be used. That is, for example, a fiber aggregate having a polyester resin fiber as a high melting point resin fiber and a polyolefin resin fiber as a low melting point resin fiber can be mentioned. In such a fiber aggregate, when the fiber aggregate is welded to other constituents, only the low melting point resin fiber can be used for welding. In this case, when the total of the high melting point resin fiber and the low melting point resin fiber is 100% by mass, the low melting point resin fiber can be, for example, 10 to 80% by mass, and further 20 to 70% by mass. can do.

Further, the resin fiber does not have to contain an additive, but may contain an additive. Examples of the additive include an antioxidant, a plasticizer, an antistatic agent, an antibacterial agent, a fungicide, a reinforcing agent, a stabilizer and the like. Only one of these may be used, or two or more thereof may be used in combination.
Further, the average fiber diameter of the fibers constituting the fiber aggregate is not limited, but can be, for example, 5 to 30 μm, preferably 10 to 25 μm. For the average fiber diameter, the average value A ₁ (average of 3 locations) of the measured fiber diameters measured using an optical microscope at three different locations of the fibers (usually single fibers) constituting the fiber aggregate was calculated. It is assumed that the further average value A ₂ (50 fibers average) of A ₁ of 50 fibers randomly selected.

(2) Deodorant The above-mentioned "deodorant" is a component having deodorant properties, and is a solid substance attached to fibers constituting a fiber aggregate via a binder resin. The deodorant used in the present invention is an inorganic deodorant containing a metal element, and is particularly preferably a component capable of adsorbing and / or decomposing an odor component by a chemical action to make it odorless or deodorized. Further, among the stoma odors, the sulfur-based component (sulfur-based gas) containing a sulfur element tends to emit a strong odor. Therefore, it is preferable that the deodorant contained in the textile product for ostomy appliances of the present invention has an excellent deodorizing action on sulfur-based components (for example, hydrogen sulfide and thiol compounds).

The structure and type of the inorganic deodorant containing a metal element are not limited, but the inorganic deodorant is mainly composed of an inorganic compound having a deodorizing action or an inorganic compound having a deodorizing action. Is preferable.
Examples of this inorganic compound include oxides (including composite oxides with other oxides), hydroxides, and inorganic acid salts (phosphates, silicates, sulfates, carbonates, etc.). Only one of these may be used, or two or more thereof may be used in combination.
Examples of the metal element contained in the inorganic deodorant include Cu, Zn, Zr, Ti, Ni, Co, Fe, Mn, Ag, W, Se, Al, Mg, Ca, Sr, Ba and the like. .. Only one of these may be used, or two or more thereof may be used in combination. Among these, Cu, Zn and Zr are preferable, and Cu and Zn are particularly preferable, from the viewpoint of the deodorizing action on the stoma odor. These inorganic deodorants containing Cu and / or Zn can exert an excellent deodorizing action on the above-mentioned sulfur-based components (sulfur-based gas). In particular, it is excellent in that it can efficiently and irreversibly deodorize sulfur-based gas by a chemical reaction with sulfur-based gas.

Specifically, the oxides include CuO / SiO ₂ composite oxide, ZnO / SiO ₂ composite oxide, copper oxide, zinc oxide, zinc oxide, zinc silicate, zinc aluminum silicate, and layered zinc aluminosilicate. Titanium oxide, aluminum oxide, magnesium oxide, calcium oxide, strontium oxide, barium oxide, zirconium oxide, tungsten oxide, cerium oxide, lithium oxide, sodium oxide, potassium oxide, zeolite (synthetic zeolite, mineral-derived zeolite), white clay, etc. Be done. Only one of these may be used, or two or more thereof may be used in combination. Further, in order to make it function more effectively as a deodorant, it may be subjected to various treatments (for example, activation treatment) (for example, activated clay, activated alumina, activated zinc oxide, etc.). Among these, CuO / SiO ₂ composite oxide and / or ZnO / SiO ₂ composite oxide are preferable. Of these, the CuO / SiO ₂ composite oxide can be said to be, for example, a carrier in which copper oxide is supported on silica gel. Further, the ZnO / SiO ₂ composite oxide can be said to be, for example, a carrier in which zinc oxide is supported on silica gel.

Examples of the inorganic salt include phosphates such as ZrCu (PO ₄ ) ₂ · H ₂ O (zirconium copper phosphate hydrate). The above-mentioned zirconium copper phosphate hydrate can be obtained, for example, by reacting layered zirconium phosphate Zr (HPO ₄ ) ₂ · H ₂ O with a divalent copper salt, and the reaction is produced. The product may contain impurities such as raw materials and a part thereof.
Further, examples of the inorganic salt include sulfates such as copper sulfate and zinc sulfate. Only one of these may be used, or two or more thereof may be used in combination. Further, these sulfate compounds can be used as a deodorant more effective against stoma odor by using them in combination with silica gel composed of an inorganic compound (SiO ₂ or the like) containing no metal element.

The shape of the inorganic deodorant containing a metal element is not limited, and various shapes can be used. For example, it can be granular, lumpy, needle-shaped or the like. Further, it can be used as a porous shape of primary particles (activation), secondary particles obtained by aggregating primary particles (granulated particles, aggregated particles), and the like. Only one of these may be used, or two or more thereof may be used in combination.
Further, the size of the particles constituting the inorganic deodorant containing a metal element is not limited, but for example, the median diameter based on the volume can be 0.05 to 100 μm, preferably 0.1 to 50 μm. It is more preferable than 0.2 to 30 μm. Since the particle size is appropriately large, the deodorant particles can be exposed from the binder resin without the particles constituting the deodorant being overcoated with the binder resin, and an excellent deodorizing effect can be exhibited. Can be done. From this point of view, for example, an inorganic deodorant made of silicate is more likely to have a larger diameter than an inorganic deodorant made of phosphate, so an inorganic deodorant having a large particle size can be used. From the viewpoint of utilization, an inorganic deodorant composed of silicate can be selected.
On the other hand, if particles larger than 100 μm are used, the surface area of the exposed particles per unit mass becomes small, and it tends to be difficult for the deodorant to act efficiently. The median diameter is measured by a laser diffraction type particle size distribution measuring machine.

Furthermore, the higher the contact efficiency of the inorganic deodorant containing a metal element with the odor component, the more excellent the deodorizing effect can be exhibited. Therefore, the ratio of the particles constituting the inorganic deodorant containing the metal element surface area is preferably in the 5~800m ² / g, and more preferably in the 10~600m ² / g. The specific surface area is measured by the BET method calculated from the amount of nitrogen adsorbed.

The amount of the inorganic deodorant (inorganic deodorant containing a metal element) contained in the textile product for the stoma device is not limited, but is preferably 1 g / m ² or more, and is preferably 3 g / m ² or more. It is more preferable to have it, and it is particularly preferable that it is 5 g / m ² or more. On the other hand, the upper limit of the amount of the inorganic deodorant (inorganic deodorant containing a metal element) contained in the textile product for the ostomy appliance is not limited, but is usually 30 g / m ² (that is, 30 g / m ^2). Below).
In addition, when the entire fiber aggregate (state in which the inorganic deodorant containing a metal element is not attached) constituting the fiber product for this stoma device is 100 parts by mass, the inorganic system containing the metal element is used. The deodorant is preferably 1 to 60 parts by mass, more preferably 2 to 50 parts by mass, and particularly preferably 5 to 40 parts by mass.

In addition, as a deodorant constituting the textile product for a stoma device of the present invention, a deodorant other than the above-mentioned inorganic deodorant containing a metal element is contained together with an inorganic deodorant containing a metal element. be able to. That is, as other deodorants, inorganic deodorants containing no metal elements, organic deodorants (organic acids, organic acid salts, other compounds), natural deodorants (plants, minerals, etc.) Deodorants derived from natural products) and the like. Only one of these may be used, or two or more thereof may be used in combination.
Activated carbon that does not contain metal elements has a poor deodorizing action (action of decomposing odorous components, etc.) and can physically adsorb not only odorous components but also many components such as dissolved components in solvents, while adsorbed components. Has the problem that it can be reversibly re-emitted. In addition, it is not suitable as a deodorant in the present invention because it has a property of easily adsorbing oil. However, activated carbon to which a metal element is added and has a deodorizing action can be used as an inorganic deodorant containing a metal element in the present invention. That is, the activated carbon to which the action of chemically decomposing the odorous component is given by the addition of the metal element is included in the inorganic deodorant containing the metal element.

More specifically, examples of the inorganic deodorant containing no metal element include carbon-based deodorants (activated carbon and graphite) and silica gel (silica gel substantially composed of silicon oxide only). Only one of these may be used, or two or more thereof may be used in combination.
Examples of the organic acid include acetic acid, fumaric acid, oxalic acid, malic acid, acrylic acid and the like. Examples of the organic acid salt include acetate, fumarate, oxalate, malate and acrylate. Examples of other compounds include iron ascorbic acid compounds, metal phthalocyanine compounds, metal porphyrin compounds, flavonoid compounds, amino acid compounds, tannin compounds, saccharides and the like. Only one of these may be used, or two or more thereof may be used in combination.

The binder resin is preferably a polymer (hydrophilic resin) exhibiting hydrophilicity, and in particular, a hydrophilic polymer having a solubility parameter (SP value) of 10.0 or more is preferable. The SP value will be described later.

That is, it may be an aromatic polyester (aromatic hydrophilic polyester) or an aliphatic polyester (aliphatic hydrophilic polyester). Only one of these may be used, or two or more thereof may be used in combination. The aromatic polyester is a polyester composed of only aromatic constituent units, an aromatic constituent unit (a constituent unit derived from an aromatic monomer, the same applies hereinafter), and an aliphatic constituent unit (aliphatic). It means a polyester having both a constituent unit derived from a monomer (the same applies hereinafter) and having a larger proportion of aromatic constituent units than an aliphatic constituent unit. On the other hand, the aliphatic polyester is a polyester composed of only an aliphatic constituent unit, an aliphatic constituent unit (a constituent unit derived from an aliphatic monomer, the same applies hereinafter) and an aromatic constituent unit (aromatic constituent unit). It means a polyester having both a constituent unit derived from a monomer (the same applies hereinafter) and having a larger proportion of an aliphatic constituent unit than an aromatic constituent unit.
Further, the hydrophilic polyester may be a saturated polyester or an unsaturated polyester. Only one of these may be used, or two or more thereof may be used in combination. Of these, saturated polyester is preferred.

Such a hydrophilic polyester can be obtained as a polycondensate by using, for example, an acid component and a hydroxyl group-containing component.

Specifically, examples of the hydrophilic polyester include polyethylene terephthalate, polybutylene terephthalate, and polylactic acid. Only one of these may be used, or two or more thereof may be used in combination.
These hydrophilic polyesters may be obtained by any method. For example, it can be obtained by a known method such as a melt polymerization method, a solution polymerization method, or a solid phase polymerization method.
The above-mentioned hydrophilic group may be introduced in any way, and can be introduced by a known method. For example, when -COO- was introduced as a hydrophilic group, trimellitic anhydride, trimellitic acid, pyromellitic anhydride, pyromellitic acid, trimesic acid, cyclobutanetetracarboxylic acid, dimethylolpropionic acid and the like were used. After the polycondensation reaction, a method of subjecting to a neutralization reaction using an amino compound, ammonia or an alkali metal salt and the like can be applied.

In the present invention, the SP value is defined as "Polymer Handbook Second Edition" [H. Burrell: (1975)] measured or calculated according to the method described on pages IV-337-IV-359.
That is, when the hydrophilic polymer is a homopolymer, its SP value is calculated by the following formula (1) based on the molecular attractiveness constant G of the structural unit constituting the homopolymer.
SP = dΣG / M ... (1)
(In the formula (1), "d" is the density (g / l) of the homopolymer, "ΣG" is the sum of the intermolecular attractive constants in the molecule of the constituent unit, and "M" is the constituent unit. Molecular weight (g / mol).)
On the other hand, when the hydrophilic polymer is a copolymer, the SP value of the copolymer is calculated by calculating the SP value of each homopolymer of each structural unit constituting the copolymer by the following formula (1). It is calculated by multiplying each SP value by the mole fraction of each constituent unit. That is, for example, in the case of a copolymer having a structural unit A having a molar fraction of X _A % and a structural unit B having a molar fraction of X _B %, it is calculated by the following formulas (2) to (4).
SP = SP _A x (X _A / 100) + SP _B x (X _B / 100) ... (2)
_{SP A = d A ΣG A /} M A ··· (3)
_{SP B = d B ΣG B /} M B ··· (4)
(Note that in equation (2) to (4), "d _A" is the density of the homopolymer consisting of structural units A (g / l), "ShigumaG _A" molecular attraction in the molecule of the structural unit A is the sum of the constant _{"M a"} is the molecular weight of the structural unit a (g / mol), a _{"d B"} density of the homopolymer consisting of structural unit B (g / l), "ShigumaG _B "is the sum of the molecular attraction constants in the molecule of the constituent unit B," M _B "is the molecular weight of the structural unit B (g / mol))

The above-mentioned hydrophilic polymer (polymer having an SP value of 10 or more) has a larger SP value than a conventionally used binder resin such as a so-called aqueous acrylic emulsion, and therefore, as a binder resin in the present invention. Suitable.
Further, when the above-mentioned hydrophilic polyester and polyvinyl alcohol are compared, it is more preferable to include the hydrophilic polyester as the binder resin. Polyvinyl alcohol is often more water-soluble than hydrophilic polyester. This is because the water-soluble binder resin tends to swell due to contact with moisture and may be clogged.

For this reason, the textile product for ostomy appliances is immersed in water at a temperature of 25 ° C. for 60 minutes, pulled out of the water, and then dried without heating (initial mass W ₀ , It is preferably 30% or less (W ₀ − W ₁ / W ₀ ≦ 0.3) (the mass is W ₁ after immersion and drying). The mass reduction rate is more preferably 25% or less, and particularly preferably 20% or less.

The amount of the binder resin contained in the textile product for the stoma device is not limited, but when the total amount of the deodorant is 100 parts by mass, the binder resin is preferably 10 to 200 parts by mass, more preferably 30 to 100 parts by mass. , 40 to 60 parts by mass is more preferable. This amount ratio is particularly preferable when the total amount of the binder resin is a hydrophilic polymer and the total amount of the deodorant is an inorganic deodorant containing a metal element.

The air permeability of the textile product for this ostomy appliance is not limited, but for example, in the air permeability measured by the Frazier method of JIS L1096: 2010, 40 to 400 cm ³ / (cm ² · s) is preferable, and 60 to 350 cm ³ / (Cm ² · s) is more preferable, and 100 to 300 cm ³ / (cm ² · s) is even more preferable. In this range, the deodorizing effect can be sufficiently exerted without obstructing the gas flow inside and outside the stoma pouch.
Also, the basis weight of fiber products for the ostomy appliance is not limited, for example, preferably from 15 to 100 / ^{m 2,} more preferably 20~90g / ^{m 2,} more preferably 30 to 80 g / ^{m 2.} Within this range, sufficient breathability and deodorant effect as a textile product for ostomy appliances can be obtained.

The textile product for an ostomy appliance of the present invention may consist of only one layer or two or more layers. When it is composed of two or more layers, for example, another fiber aggregate layer, a film layer, an adhesive layer, or the like can be used. Only one of these may be used, or two or more thereof may be used in combination.
That is, for example, the following (1) to (5) and the like are exemplified as the multi-layered textile product for an ostomy appliance.
(1) A fiber product for ostomy appliances composed of only layer S ₁ (layer S ₁ is a fiber aggregate in which a deodorant is attached to constituent fibers via a binder resin, see FIG. 1).
(2) Textile products for stoma orthoses in which layer S ₁ and layer S ₂ are laminated (layer S ₂ is a deodorant other than an inorganic deodorant containing a metal element in its constituent fibers via a binder resin. There the deposited fiber assembly, the layer S ₁ and the layer S ₂ may be laminated without being entangled may be entangled laminate, see Fig. 2a).
(3) layer S ₁ and the layer S ₃ and the ostomy appliance for textile products that are stacked (layer S ₃ is a film layer, for example, when a waterproof layer, see FIG. 2a).
(4) A textile product for a ostomy appliance in which a layer S ₁ and a layer S ₄ are laminated (see FIG. 2a when the layer S ₄ is a film layer and, for example, the layer S ₄ is a waterproof layer).
(5) Textile product for ostomy appliance in which layer S ₁ , layer S ₄ and layer S ₅ are laminated in this order (layer S ₄ is a film layer, for example, layer S ₄ is a waterproof layer and layer S ₅ Is the adhesive layer, see FIG. 2b).

The textile product for a ostomy appliance of the present invention may have the above-mentioned structure, and the manufacturing method thereof is not limited. For example, a deodorant and a binder are attached to a fiber aggregate (a base cloth to which a deodorant is not attached). It can be obtained by applying a processing liquid containing a resin (padding, dipping, coating, spraying, printing, etc.) and then drying.
Of these, according to the padding method and the dipping method, the deodorant can be more uniformly fixed on the surface of the base cloth as compared with other methods. Therefore, the deodorant is more exposed to the air layer surface, and a textile product for a ostomy appliance that can exhibit more excellent deodorizing performance can be obtained. Examples of the padding method include a pad dry method and a pad steam method.

Additives can be added to the above processing liquid in addition to the deodorant and the binder resin. Examples of additives include dispersants, antifoaming agents, viscosity modifiers, surfactants, pigments, dyes, fragrances, antibacterial agents, antiviral agents, antiallergen agents and the like.
When two or more different deodorants are used in combination, a plurality of processing liquids individually adjusted can be used for spreading processing, if necessary.

The fiber aggregate on which the processing liquid is spread can be heat-dried (for the purpose of removing the medium contained in the processing liquid, etc.), if necessary. In this case, it is preferable to heat in the range of 110 ° C. to 150 ° C. In this range, it is possible to suppress the exertion of a peculiar odor generated by heating. This temperature is more preferably in the range of 120 ° C to 140 ° C, and particularly preferably in the range of 123 ° C to 138 ° C in consideration of productivity. Further, the drying time is not limited, but can be 2 to 10 minutes, preferably 2 to 5 minutes.

[2] Applications of textile products for ostomy appliances The textile products for ostomy appliances of the present invention can be used as components constituting ostomy appliances. Although the specific use is not limited, it can be used, for example, as a deodorant filter for a ostomy pouch constituting a ostomy appliance. Further, the textile product for a ostomy appliance of the present invention can be used as a deodorant sheet for a ostomy pouch constituting the ostomy appliance. In this case, the deodorant sheet for the ostomy pouch can be a sheet that covers at least a part of the outside of the ostomy appliance.
These configurations will be described in detail in the description of the ostomy appliance below.

[3] Stoma orthosis (1)
The ostomy appliance 2 of the present invention (see FIGS. 3 to 8) is a ostomy having a side wall 22a on the body side having an opening 221 for receiving the ostomy and an outer side wall 22b facing the side wall 22a on the body side. It has a pouch 21.
Then, at least one side wall 22 of the side wall 22a on the body side and the outer side wall 22b has a degassing hole 23 for letting gas in the stoma pouch 21 escape to the outside, and at least one of the inside and outside of the degassing hole 23. It has a ventilation filter 24 arranged on one side. The ventilation filter 24 includes the textile product 1 for an ostomy appliance of the present invention.

As mentioned above, waste products will be stored in the stoma pouch, but since this waste product contains gas containing odorous components, the stoma pouch will be filled with gas and swell by use. .. When the stoma pouch swells, it is easy to peel off from the body, and the wearing part appears to swell when viewed from the outside of the clothes. Therefore, it is preferable that the filled gas is easily discharged from the stoma pouch. However, the conventionally provided ventilation filter is blocked in a short period of time due to contact with oil in the waste product, and eventually, a separate discharge port (reference numeral 29 in FIGS. 3 to 8) is opened to discharge the filled gas. There is a problem that we have to do it. Further, there is a problem that deodorization cannot be performed in such an exhaust form.

In this regard, as described above, in the fiber product 1 for a stoma device of the present invention, an inorganic deodorant (deodorant 12) containing a metal element in the fibers constituting the fiber aggregate as the support is used. A hydrophilic polymer is attached as a binder resin. Therefore, it is possible to exhibit particularly excellent deodorizing performance in stoma applications. In particular, it is excellent in deodorizing properties in the presence of oil (oil and lipophilic components), and can also exhibit excellent deodorizing properties in water systems as well. That is, it is possible to prevent the deodorant from being covered with the oil content that can be contained in a large amount in the waste products stored in the stoma pouch, and to prevent the fiber aggregate from being blocked by the oil content. Furthermore, since the sulfur-based component that emits a particularly strong odor exhibits water solubility, it is possible to provide a hydrophilic reaction field in which this sulfur-based component can easily react with a deodorant. Therefore, by using the textile product 1 for an ostomy appliance 1 of the present invention as the ventilation filter 24 of the ostomy appliance 2, it is possible to exhibit excellent deodorant characteristics while maintaining ventilation even in the presence of oil.

As a result, it can be fixed to the side wall 22.

[Embodiment 2]
The ostomy appliance 2 of the second embodiment (see FIGS. 6 to 8) is a ostomy appliance 2 having a side wall 22a and a side wall 22b sealed along the periphery thereof and an outlet 29, similarly to the first embodiment. It has a pouch 21. The same applies to the sealing and discharge of waste products as in the first embodiment, and the same applies to the fact that a hook-and-loop fastener or the like can be provided. Further, the same applies to the fact that, for example, a fixing portion for fixing to the user's body can be provided as the face plate 27.

On the other hand, in the second embodiment, the ventilation filter 24 is arranged so as to further cover the adsorption filter 26 (including activated carbon) arranged so as to cover the degassing hole 23, as illustrated in the enlarged view of FIG. .. More specifically, the adsorption filter 26 is fixed to the side wall 22 by the peripheral edge thereof being surrounded by the side wall piece 22b'and the side wall piece 22' being welded to the side wall 22b (this is the same as in the first embodiment).

As described above, the waste products stored in the stoma pouch 21 contain an odor component. Since the stoma pouch 21 is sealed, odor does not normally leak out, but when the contents are discharged from the discharge port 29, the odor component is released to the outside without coming into contact with the deodorant. To. In such a case, it is preferable that a textile product for a ostomy appliance containing a deodorant is arranged in the vicinity thereof. When it is discharged, an opportunity for contact with the odorous component is obtained, and the released odorous component can be deodorized. A covering sheet 25 can be mentioned as a configuration capable of forming such an opportunity.
That is, conventionally, a ostomy appliance 2 provided with a non-contact sheet formed of a non-woven fabric or the like in order to avoid direct contact between the body-side mounting portion and the body-side side wall 22a has been known. By using the textile product 1 for ostomy appliances of the present invention as this non-contact sheet, excellent deodorizing performance can be exhibited. The non-contact sheet has many opportunities for contact with water and oil due to sweating from the wearing portion on the body side, but the textile product 1 for ostomy appliance 1 of the present invention is not hindered by contact with these. Since it has odor characteristics, it can exhibit excellent deodorizing performance.

[2] Evaluation of textile products for ostomy appliances (1) Normal sensory test 30 mm × so as to cover the adsorption filter (activated carbon filter, 20 mm × 12 mm × 1 mm) of the ostomy pouch 21 (300 mm × 150 mm) in which the opening 221 is sealed. Test stoma orthosis 2 (Embodiment 2, FIGS. 6 to 6), which is closed with one piece of each ostomy appliance fiber product (functioning as a ventilation filter 24) of Examples 1 to 9 and Comparative Examples 1 to 4 cut out to 40 mm. 8) was prepared.
Next, 500 mL of a test gas of hydrogen sulfide, methyl mercaptan, or ammonia having a concentration of odor intensity 5 was injected into the ostomy pouch 21 of the ostomy appliance 2. Further, the stoma pouch 21 (inner bag) infused with the test gas was sealed in a polyethylene bag (outer bag) having a capacity of 10 L inflated with dry air. Then, one hour after this encapsulation, after confirming that the test gas was released from the stoma pouch 21 (the side walls 22a and 22b were in close contact with each other), the odor of the gas in the polyethylene bag was 6 A human subject was made to smell, and the odor intensity was judged according to the following criteria. Then, the odor intensities of the six persons were averaged and shown in Tables 1 to 3 as the odor intensities of the normal sensory test. The smaller the odor intensity value, the higher the deodorizing effect. The above-mentioned concentration of odor intensity 5 is 8 volume ppm for hydrogen sulfide, 0.2 volume ppm for methyl mercaptan, and 40 volume ppm for ammonia.
Odor intensity 0: Odorless.
Odor intensity 1: Perceptible odor.
Odor intensity 2: A weak odor that tells you what the odor is.
Odor intensity 3: Easily perceptible odor Odor intensity 4: Strong odor.
Odor intensity 5: Strong odor.

(2) Oil resistance sensory test The textile products for ostomy appliances of Examples 1 to 9 and Comparative Examples 1 to 4 were immersed in 100 mL of commercially available prepared milk (milk fat content of 3.5% or more) for 1 hour, and then ionized. Odor intensity was determined in the same manner as in (1) above, except that a textile product for ostomy appliances was used, which was obtained by rinsing with exchanged water (100 mL) three times and then drying at 60 ° C. for 30 minutes to adsorb the obtained oil. Was done. Then, similarly, the odor intensities of the six persons were averaged, and the odor intensities of the oil resistance sensory test are also shown in Tables 1 to 3. The smaller the odor intensity value, the higher the deodorizing effect.

From the results in Table 1, since the binder resin contains a polymer having an SP value of 10 or more, it has an excellent deodorizing action equivalent to that in an environment in which it comes into contact with oil but not in contact with oil. It can be seen that That is, it can be seen that excellent oil resistance can be exhibited.
Specifically, Examples 1 to 3 using a polymer having an SP value of 10.6 to 12.6 as a binder resin and a polymer having an SP value of 8.4 to 9.3 as a binder resin. Compared with Comparative Examples 1 and 2 used, the results of the normal sensory test (deodorization in an environment without oil) show almost no difference, while the oil resistance sensory test (deodorization in an environment with oil). Was significantly reduced in Comparative Examples 1 and 2 in which a polymer having an SP value of 8.4 to 9.3 was used as the binder resin.

In this respect, when Example 1 and Example 2 are compared, it can be seen that when a polymer having the same SP value is used as the binder resin, the oil resistance sensory test also gives the same result. In addition, comparing Examples 1 to 3, Example 3 using PVA exhibiting water solubility is slightly inferior to Examples 1 and 2 in the normal sensory test, but is superior in the oil resistance sensory test. I understand. It is considered that this is because the deodorant is covered more by the binder resin in Example 3 than in Examples 1 and 2.

From the results in Table 2, it can be seen that various combinations of inorganic deodorants containing metal elements can be used. On the other hand, when activated carbon, which is an inorganic deodorant that does not contain metal elements, is used, it is stronger than the influence of the SP value of the binder resin, and it is greatly affected by the properties of the activated carbon itself, and a sufficient deodorizing effect is obtained. It turns out that it has not been done. In addition, it can be seen that the results of the oil resistance sensory test are significantly inferior to those of each example.
Furthermore, from the results in Table 3, it can be seen that the spreading amount of the inorganic deodorant containing a metal element can be used in a wide range of 3.0 to 12.0 g / m ² . Similarly, it can be seen that the spreading amount of the binder resin can be used in a wide range of 3.0 to 12.0 g / m ² . If the spread amount of the inorganic deodorant containing a metal element exceeds 12.0 g / m ² , there is a risk that the inorganic deodorant may fall off. Similarly, even if the spreading amount of the binder resin is less than 3.0 g / m ² , there is a concern that the inorganic deodorant may fall off.

In the present invention, the examples are not limited to those described in the above specific examples, and examples can be variously modified within the scope of the present invention according to the purpose and application.
