Description

  The present invention relates to bedding with stuffing such as quills, feathers used as stuffing for garments with stuffing, and bedding such as quilts stuffed with the feathers, and clothing stuffed with the feathers. The present invention relates to feathers excellent in antibacterial power, antifungal power, and antifouling power, bedding such as a quilt packed with the feathers, and clothing packed with the feathers.

  The feather according to the present invention includes a down (cotton feather), a feather (feather), and a small feather (small feather).

  In recent years, with the improvement of living standards, awareness of health and hygiene has also increased, and there is a high need for deodorant properties, antibacterial properties, antifouling properties and the like.

  In the first place, during sleep, sweat, sebum containing nutrients, old keratinocytes that fall off the skin, etc., adhere to the pods. It is well known empirically that this adhesion causes a bad odor.

  In addition, the sweat, sebum, and old keratinous cell pieces penetrate into the inside of the basket and become dirt and adhere to the filling. In the future, bad odors may be generated and unpleasant feelings may occur. If this is left unattended, various germs and molds are generated, which poses a health problem. Moreover, when smoking a cigarette on bedding, there exists a problem which a tobacco odor tends to adhere.

  Conventionally, many techniques for solving the above problems and deodorizing functions have been proposed. These can be broadly classified into three categories: a sensory deodorization method, a physical deodorization method, and a chemical deodorization method that chemically changes an odorous substance into another substance that does not smell so much.

  The sensory deodorization method is to remove the odor with a strong fragrance or to remove the odor sensuously with a plant-based refined oil such as camphor oil, needle oil or eucalyptus oil. However, these sensory deodorization methods do not help the fundamental solution by merely hiding odors that are unpleasantly sensed.

  In addition, the physical deodorization method is to confine the odor substance in a porous substance such as activated carbon or zeolite and suppress volatilization. However, these physical deodorization methods can deodorize the surrounding atmosphere, but the odor source is adsorbed to the stuffing itself, so there is a bad smell in the immediate vicinity of the stuffing, and the face is directly like a futon or pillow. If it touches, it may give off an unpleasant odor.

  Further, the chemical deodorization method is to deodorize by chemically changing the odorous substance to another substance that does not smell so much or by chemically adsorbing the odorous substance. These chemical deodorization methods are effective deodorization means because the odor itself disappears, but there is a problem that the deodorization effect is limited in principle.

  Furthermore, in recent years, a technique has been proposed that has a function of oxidizing / decomposing a substance itself that is a source of odor by using photocatalysis. This technology oxidizes / decomposes the odor source itself and is expected to have anti-odor, antibacterial and antifouling effects, and is attracting attention as a promising technology. There were problems such as risk of adverse effects such as deterioration of strength.

  The feather 10 according to the first embodiment shown in FIG. 1 and FIG. 2 is an inorganic composite antibacterial agent in which the original feather 1 is a base material 2 and the surface of the base material 2 is composed of an apatite 4 and a titanium dioxide photocatalyst agent 5. 3 is attached by spraying.

The inorganic composite antibacterial agent 3 is obtained by immersing a titanium dioxide photocatalyst agent 5 having a surface in a simulated body fluid (not shown) to cover the surface with a porous calcium phosphate film (apatite 4), It is mixed in the binder 6 and can be attached to the surface of the substrate 2 by spraying. The simulated body fluid includes NaCl, NaHCO ₃ , KCl, K ₂ HPO ₄ · 3H ₂ O, MgCl ₂ · 6H ₂ O, CaCl ₂ , Na ₂ SO ₄ , HCl, (CH ₂ OH) ₃ CNH ₂ , by using the distilled ^{water, Na +147 mM, K +5 mM} , Ca 2 +2.5 mM, Mg 2 +1.5 mM, Cl -147 mM, HCO 3 -4.2 mM, HPO 42 -1.0 mM, SO 42 - What was adjusted to the aqueous solution of pH 7.4 by the composition of ^0.5 mM is preferable.

  Incidentally, the inorganic composite antibacterial agent 3 can function sufficiently and exhibit its effect as long as light (ultraviolet rays) is in a state of reaching the surface of the titanium dioxide photocatalyst agent 5. It is desirable that the surface of the photocatalytic agent 5 is appropriately coated with the apatite 4. The film may not be completely covered or may have a thin film portion. In short, preferably, it is desirable that the adsorption function of the apatite 4 be efficiently regenerated, and an effect can be expected.

The inorganic composite antibacterial agent 3 is adhered by spraying at a temperature of 70 to 110 ° C. for 30 to 15 minutes immediately after the drying process of the original feathers after washing and dehydration. In addition, the inorganic composite antibacterial agent 3 adheres by spraying in a drying kettle having a temperature of 125 to 135 ° C. and a pressure of 2.5 to 3.5 kg / cm ² during the drying process of the original feathers after washing and dehydration. It can be carried out. In this case, a product excellent in water repellency and waterproofness can be obtained by mixing and spraying the inorganic composite antibacterial agent 3 in a solution of Teflon (trade name of tetrafluoroethylene polymer). The solution of Teflon (trade name of tetrafluoroethylene polymer) functions as a binder.

  The binder 6 may be at least one selected from alkyl silicate resins, silicone resins, fluorine resins, acrylic resins, urethane resins, polyester resins, and others.

  In the present invention, a titanium dioxide photocatalytic agent is preferable among titanium oxides, and porous calcium phosphate is preferable among apatites. Furthermore, the inorganic composite antibacterial agent 3 is preferably an environmental purification material described in, for example, Japanese Patent No. 3275032.

  The adhesion amount of the inorganic composite antibacterial agent 3 to the substrate 2 is preferably 0.1 to 0.2% by weight. The mixing amount of the inorganic composite antibacterial agent 3 with respect to the binder 6 is preferably 0.5 to 1.0% by weight. Further, it is preferable to use an acrylic resin or a urethane resin as the binder, since the washing durability, the texture of the product, the cost, etc. are drastically improved.

  The feather 20 according to the second embodiment shown in FIG. 3 is obtained by attaching the inorganic composite antibacterial agent 21 in the following manner (production method).

  That is, immediately after the drying process of the original feathers after washing and dehydration, a binder 23 not mixed with an inorganic composite antibacterial agent is adhered to the surface of the original feathers (base material) 22 to form an adhesive surface 24, and this adhesion While the surface 24 has adhesive strength (during melting), the powdery inorganic composite antibacterial agent 21 previously obtained in the same manner as described above is applied to the surface of the adhesive surface 24, and thereafter The binder 23 and the adhesive surface 24 are cured.

  The feather 20 according to the second embodiment obtained by the above procedure (manufacturing method) is functionally preferable because the exposed area of the inorganic composite antibacterial agent 21 is totally wide as can be seen from FIG. In the feather 20 according to the second embodiment, it is desirable that the exposed portion of the inorganic composite antibacterial agent 21 does not fall off due to contact with other things.

  4 is completed by filling the feathers 10 and 20 in the cocoon bark 31.

  The garment 40 according to the fourth embodiment shown in FIG. 5 is completed by filling the feathers 10 and 20 in an outer cloth 41.

In the first place, when the titanium dioxide photocatalyst agent 5 used in each of the above embodiments is singly mixed into a resin or organic paint,
a. Since the base material and the binder itself are disassembled and discolored or raged, they cannot be mixed and applied as they are.
b. In addition, it cannot attract organic substances or bacteria that are released into the atmosphere or dispersed in the liquid, or can absorb a large amount, so that only substances that have been in contact for a relatively long time can be decomposed.
c. Furthermore, it will not function at all unless exposed to light,
It has such a defect.

  Therefore, each of the above-described embodiments employs an inorganic composite antibacterial agent in which nanometer order apatite crystals are deposited on the surface of the titanium dioxide photocatalyst agent 5 so as to eliminate the above-mentioned drawbacks.

  In each of the above embodiments, the apatite functions as an adsorbent that adsorbs a large amount of proteins such as bacteria and viruses and organic compounds such as ammonia, nitrogen oxides, and aldehydes even when not exposed to light.

  In addition, the titanium oxide (titanium dioxide) photocatalyst agent has a detoxifying power that decomposes / removes harmful organic compound substances, bacteria, odors, etc. into carbon dioxide gas or water by exerting strong oxidizing power when exposed to light. It functions as a photocatalytic agent.

  That is, the inorganic composite antibacterial agent is an inorganic composite antibacterial body having both an adsorption function and a decomposition function, and has the following characteristics.

(1) Toxic substances adsorbed on apatite are decomposed and removed by titanium oxide (titanium dioxide) photocatalyst when exposed to light, so the apatite adsorption function will be regenerated each time and used semipermanently. You can continue.
(2) A large amount of bacteria and harmful substances can continue to be adsorbed by apatite, even in the dark, even in the dark, even in the dark, even in the night, as well as in the outer cover of clothing and clothing. Adsorbing and removing functions can be demonstrated for several days even if there is no light, as long as it is a harmful substance in the basket or clothing.
(3) Apatite coated with a titanium oxide (titanium dioxide) photocatalytic agent functions to isolate feathers from titanium oxide (titanium dioxide). Therefore, titanium oxide (titanium dioxide) does not weaken the feathers that are the base material.
(4) Since the titanium oxide (titanium dioxide) photocatalytic agent can decompose harmful substances in the state captured by apatite, it can be efficiently and reliably decomposed even with a small amount of light. (In the first place, since titanium oxide requires a certain amount of time to decompose organic substances into carbon dioxide and water, only substances that happen to stay on the surface for a certain amount of time can be decomposed.)

  The titanium oxide (titanium dioxide) photocatalyst is mainly excited by ultraviolet rays and has a property of oxidatively decomposing organic substances with a strong oxidizing power. Specifically, it has a crystalline structure called anatase type or rutile type. It has something.

  In short, the present invention is characterized in that the adsorbent has an adsorptive power for adsorbing organic substances such as bacteria and ammonia odor even when not exposed to light, and that the organic substance when the photocatalytic agent (titanium dioxide) is exposed to light. It has been focused on the fact that it has the ability to decompose and detoxify, that is, the debromating power, the ability to decompose and remove colored substances (antifouling power), and the bactericidal power (antibacterial power and antifungal power).

  Examples of the present invention will be described below.

  In the same manner as in the conventional method, the original feathers (20 kg) were subjected to pre-dust removal → washing → dehydration treatment, and then put in a drying pot (not shown) at a temperature of 110 ° C. and dried for 15 minutes. The tip of the nozzle of the spraying device faces the inside of the drying kettle, and the mixed solution of the inorganic composite antibacterial agent 3 diluted with water from the nozzle during drying is 37.5% (7.5 liters) by weight. Sprayed.

  As a result, 90% of the sprayed mixed solution of the inorganic composite antibacterial agent 3 adhered to the substrate 2, and the inorganic composite antibacterial agent 3 could adhere to the surface of the substrate 2.

  In addition, if a fluorescent agent (for example, 0.2 to 0.3% in weight ratio to feathers) is added and mixed in the mixed solution of the inorganic composite antibacterial agent 3 and sprayed, the fluorescent solution is mixed with the mixed solution of the inorganic composite antibacterial agent 3. It is preferable that the agent adheres to the base material (original feather) and the degree to which the inorganic composite antibacterial agent 3 adheres to the base material 2 (original feather) can be visually determined.

  In addition, when quality evaluation, such as ammonia adsorption property, deodorizing property, and antibacterial property, about the said Example was performed, it was as the table | surface shown next.

  As can be seen from Table 1, the examples show excellent performance with respect to ammonia adsorption, exhibiting a very high level of function.

  As can be seen from Table 2, it can be seen that the examples are superior in that they exhibit a very high level of function for deodorizing ammonia and acetic acid.

  As is apparent from Table 3, the examples are excellent in antibacterial properties, exhibiting a very high level of function.

  Moreover, about the feather which concerns on 1st Embodiment, the bulkiness test was done by the comparison with the feather before processing, the feather after processing, and the conventional feather. In this test, Chinese white goose down was used and measured according to JIS L-1980 and Hiwa Kyo B method (pretreatment).

  That is, a sample having a durability test weight of 50 g is placed in a small pillow having a size of 30 cm × 30 cm, accommodated in a vertical cylindrical container having a diameter of 30 cm and a height of 60 cm, and an iron disk having a diameter of 20 cm is fixed to the lower end of the rod. Using a tester that moves up and down by the cylinder, a resistance test was performed in which the small pillow was pressed 1000 times with the disk, and then the sample was removed from the small pillow and placed in a transparent cylinder with an inner diameter of 290 mm and a height of 500 mm. Then, an aluminum load disk having a weight of 120 g and a diameter of 285 mm was placed thereon, and the bulkiness was measured. The results are shown in Table 4.

  As is apparent from Table 4, it can be seen that the post-process feathers have significantly increased bulkiness.

  In addition, as a result of creating a quilt and clothes using the feathers of the above-mentioned examples and conducting a practical test, it was confirmed that they had an extremely excellent deodorizing effect and antibacterial effect.

  The present invention uses a composite agent of an inorganic antibacterial agent such as apatite and silver as an inorganic composite antibacterial agent, a composite agent of zeolite and a titanium oxide photocatalyst as an inorganic composite antibacterial agent, and an inorganic antibacterial agent such as zeolite and silver This composite agent can be used as an inorganic composite antibacterial agent, and as an inorganic antibacterial agent, a metal, such as silver, copper, or zinc, and a compound or a mixture thereof supported on an inorganic substance can be used.

  The feathers obtained by the implementation of the paragraph number [0071] and the buns and clothes using the feathers were tested, and as a result of the tests, the feathers and the buns and clothes using the feathers according to the first to fourth embodiments It was confirmed that the same effect as inferior was exhibited.
