Description
本発明は、嵩高性に優れた、アレルギー抗原不活化活性を有する加工羽毛の製造方法に関する。 The present invention relates to a method for producing a processed feather having allergy antigen inactivating activity, which is excellent in bulkiness.
羽毛は、軽量で、保温性、吸湿性、弾力性等に優れた素材であり、近年、布団や寝袋等の寝具類やダウンジャケット等の防寒具等(以下、羽毛製品という)に盛んに用いられている。 Feathers are lightweight and have excellent heat retention, moisture absorption, elasticity, etc. In recent years, they are actively used for bedding such as futons and sleeping bags and cold protection equipment such as down jackets (hereinafter referred to as feather products). It has been.
通常、原料羽毛には、ホコリ、土、血液、雑菌、害虫、ダニ等が付着しているため、充分に洗浄してから使用されるが、これらの汚れを完全に除去することは困難である。また、羽毛製品は綿や化繊を用いた製品に比べると、一般家庭において頻繁に洗濯を行うことが難しく、外部から雑菌やダニ等が侵入して内部で繁殖しやすいという問題もある。 Usually, dust, dirt, blood, germs, pests, ticks, etc. are attached to the feathers of the material, so it is used after thoroughly washing, but it is difficult to remove these stains completely. . In addition, compared to products using cotton or synthetic fibers, feather products are difficult to wash frequently in general households, and there is a problem that germs, mites, etc. enter from the outside and easily propagate inside.
しかし、羽毛製品は人に直接触れるものであり、上記のような汚れが残留していたり、内部で雑菌やダニ等が繁殖すると、アレルギーや異臭の発生といった問題が生じる可能性がある。特に、ダニは、その糞、死骸、脱皮殻、卵等もアレルギー抗原となるので、非常に問題となっている。 However, feather products are those that come into direct contact with humans, and if the above-mentioned stains remain, or if germs, mites, etc. propagate inside, there is a possibility that problems such as the occurrence of allergies and odors may occur. In particular, mites are very problematic because their feces, carcasses, molting shells, eggs, etc. are allergic antigens.
上記のような問題を解決するため、原料羽毛を防ダニ剤や抗菌・防臭剤等で処理することも行われているが、化学合成品の使用は人体への安全の面で不安があり、より安全性の高い方法も提案されている。例えば、下記特許文献1には、中綿等の詰物に、タンニン酸を染み込ませることにより、前記詰物に付いているダニ抗原を人体に害のない形態に変性処理することを特徴とするダニ抗原処理方法が開示されている。 In order to solve the above-mentioned problems, raw feathers are also treated with anti-mitotic agents, antibacterial / deodorant agents, etc., but the use of chemically synthesized products is uneasy in terms of safety to the human body, A safer method has also been proposed. For example, in Patent Document 1 below, mite antigen treatment is characterized by denaturing mite antigens attached to the filling into a form that is not harmful to the human body by impregnating fillings such as batting with tannic acid. A method is disclosed.
また、下記特許文献2には、消臭性物質が固着されていることを特徴とする消臭性羽毛が開示されており、該消臭性物質としてカテキンやタンニン等の植物抽出物等が例示されている。 Patent Document 2 below discloses a deodorant feather characterized by having a deodorant substance fixed thereto, and examples of the deodorant substance include plant extracts such as catechin and tannin. Has been.
また、下記特許文献3には、羽毛を詰め込んだふとん等の、皮の一部開口部からオゾンを吹き込んだ後に、前記開口部を閉じてオゾンを封入することによって、ふとん等の内部にオゾンを残留させることを特徴とする、羽毛ふとん等の殺虫、殺菌、防臭、防カビ等の方法が開示されている。
しかしながら、羽毛を防ダニ剤や抗菌・防臭剤等の薬剤で処理すると、羽毛の持つ嵩高性が低下、すなわち「ふんわか」とした感覚が低下して、羽毛としての軽量性や保温性が損われやすいという問題があった。また、上記特許文献3に記載された方法では、効果の持続性がなかった。 However, if feathers are treated with agents such as anti-mite agents, antibacterial and deodorants, the bulkiness of the feathers is reduced, that is, the feeling of “fluffy” is reduced, and the lightness and heat retention of the feathers are impaired. There was a problem that it was easy to break. Further, the method described in Patent Document 3 has no sustained effect.
したがって、本発明の目的は、羽毛の嵩高性を損うことなく、アレルギー抗原不活化活性能を付与した加工羽毛の製造方法を提供することにある。 Accordingly, an object of the present invention is to provide a method for producing a processed feather imparted with an allergen-inactivating activity ability without impairing the bulkiness of the feather.
上記目的を達成するため、本発明の加工羽毛の製造方法は、原料羽毛を、熱風中で撹拌しながらタンニン酸水溶液を噴霧し、該原料羽毛にタンニン酸を付着させて乾燥させることを特徴とする。 In order to achieve the above object, the method for producing a processed feather of the present invention is characterized in that the raw material feather is sprayed with an aqueous tannic acid solution while stirring in hot air, and tannic acid is adhered to the raw material feather and dried. To do.
本発明においては、前記タンニン酸水溶液の濃度が0.3〜20質量%であることが好ましく、原料羽毛100質量部に対して、前記タンニン酸水溶液を3〜100質量部噴霧することが好ましい。 In this invention, it is preferable that the density | concentration of the said tannic acid aqueous solution is 0.3-20 mass%, and it is preferable to spray 3-100 mass parts of said tannic acid aqueous solution with respect to 100 mass parts of raw material feathers.
また、前記熱風の温度が60〜110℃であることが好ましい。 Moreover, it is preferable that the temperature of the said hot air is 60-110 degreeC.
更に、前記タンニン酸水溶液が抗菌剤を含有するものであることが好ましく、前記抗菌剤としては、キトサンであることが好ましい。 Further, the tannic acid aqueous solution preferably contains an antibacterial agent, and the antibacterial agent is preferably chitosan.
本発明の加工羽毛の製造方法は、布団、枕、クッション、ダウンジャケット、寝袋から選ばれた1種に適用されることが好ましい。 It is preferable that the manufacturing method of the processed feather of this invention is applied to 1 type chosen from the futon, the pillow, the cushion, the down jacket, and the sleeping bag.
本発明の製造方法によれば、原料羽毛を、熱風中で撹拌しながらタンニン酸水溶液を噴霧し、該原料羽毛にタンニン酸を付着させて乾燥させることにより、羽毛の嵩高性を損うことなく羽毛に均一にタンニン酸を付着させて、アレルギー抗原不活化活性能を有する加工羽毛を得ることができる。 According to the production method of the present invention, the raw material feathers are sprayed with an aqueous tannic acid solution while stirring in hot air, and tannic acid is attached to the raw material feathers and dried, so that the bulkiness of the feathers is not impaired. By applying tannic acid uniformly to the feathers, processed feathers having the ability to inactivate allergic antigens can be obtained.
本発明によれば、充分な嵩高性と、優れたアレルギー抗原不活化活性能を有する加工羽毛を得ることができる。 According to the present invention, a processed feather having sufficient bulkiness and excellent allergen antigen inactivating activity can be obtained.
本発明で用いられる原料羽毛は、羽毛製品に使用可能な羽毛であれば特に制限なく使用できる。通常、ダックやグース等の鳥類の羽毛が用いられ、ダウンでもフェザーでもかまわない。 The raw material feather used in the present invention can be used without particular limitation as long as it can be used for feather products. Usually, feathers of birds such as duck and goose are used, and they may be down or feathered.
また、タンニン酸は、下記一般式〔1〕で表される化合物であり、水に溶解し易く、水溶液は酸性を示す。また、アルコール、アセトン、グリセリン等に良好な可溶性を示し、石油エーテル、無水エーテル、クロロホルム等に不溶性である。 Tannic acid is a compound represented by the following general formula [1], is easily dissolved in water, and the aqueous solution is acidic. In addition, it shows good solubility in alcohol, acetone, glycerin and the like, and is insoluble in petroleum ether, anhydrous ether, chloroform and the like.
(上記一般式〔1〕式中、Rは、同一又は異なってもよい水素原子又は下記一般式〔2〕で表される化合物よりなる官能基を表す。) (In the above general formula [1], R represents the same or different hydrogen atom or a functional group composed of a compound represented by the following general formula [2].)
(上記一般式〔2〕式中、Aは、同一又は異なってもよい水素原子又は下記一般式〔3〕で表される化合物よりなる官能基を表す。) (In the general formula [2], A represents a hydrogen atom which may be the same or different or a functional group composed of a compound represented by the following general formula [3].)
タンニン酸は、没食子や五倍子等の植物タンニンに由来し、一般にガロイル没食子酸と称されることもある。また、タンニンの加水分解で生じることから「タンニン酸」の用語はタンニン自体を指称することもある。没食子や五倍子から得られるタンニン酸は、加水分解により没食子酸と微量のグルコースとを生じる。 Tannic acid is derived from plant tannins such as gallic and pentaploids, and is sometimes sometimes referred to as galloyl gallic acid. In addition, the term “tannic acid” may refer to tannin itself because it is generated by hydrolysis of tannin. Tannic acid obtained from gallic and pentaploids produces gallic acid and trace amounts of glucose by hydrolysis.
本発明において用いられるタンニン酸は、例えば、没食子や五倍子等を温湯で抽出して、抽出液を蒸発乾固して得たもの、また、これらを有機溶媒で抽出・精製したもの等、公知技術に準じた抽出方法によって得られるものであり、具体的には、加水分解型ガロタンニン、加水分解型エラジタンニン及び縮合型タンニンから選ばれた少なくとも1種が好ましく用いられ、例えば、商品名「タンニン酸AL」(富士化学工業株式会社製)等の市販のものを用いることができる。 The tannic acid used in the present invention is, for example, a product obtained by extracting gallic or pentaploid with hot water and evaporating the extract to dryness, or extracting and purifying these with an organic solvent. Specifically, at least one selected from hydrolyzed gallotannin, hydrolyzed ellagitannin and condensed tannin is preferably used. For example, the trade name “Tannic acid AL” is used. Commercially available products such as “Fuji Chemical Industry Co., Ltd.” can be used.
タンニン酸は、後述する実施例に示されるダニやその糞、死骸等といったダニ抗原以外にも、花粉、動物(例えば、イヌ、ネコ、鳥、ハムスター等のげっ歯類)由来の抗原、真菌等を吸着して不活化する作用を有しているが、不活化のメカニズムについては未だ解明されていない。また、羽毛のタンパクを変性し、羽毛アレルギーを防ぐ効果も有している。 Tannic acid is not only mite antigens such as mites, their feces, carcasses, etc., which will be described later, but also pollen, antigens derived from animals (eg, rodents such as dogs, cats, birds, hamsters), fungi, etc. Has the effect of adsorbing and inactivating, but the mechanism of inactivation has not been elucidated yet. It also has the effect of denaturing feather proteins and preventing feather allergies.
以下、本発明の加工羽毛の製造方法について説明する。 Hereinafter, the manufacturing method of the processed feather of this invention is demonstrated.
原料羽毛の洗浄は常法にしたがって行うことができる。すなわち、汚れた羽毛から、埃、泥、小石等の夾雑物を取り除いた後、洗剤を用いて洗浄し、羽毛に付着している泥、血液、肉片等の汚垢を除去し、充分にすすぎを行い、遠心分離機等により脱水する。 The raw material feathers can be washed according to a conventional method. That is, after removing dirt, mud, pebbles and other contaminants from dirty feathers, wash with a detergent to remove dirt, mud, blood, meat pieces, etc. adhering to the feathers and rinse thoroughly. And dehydrate using a centrifuge.
本発明においては、上記のようにして得られた羽毛にタンニン酸を付着させればよい。具体的には、脱水後の羽毛を、60〜110℃、好ましくは80〜100℃の熱風中で、撹拌棒や撹拌羽根等を用いて撹拌しながらタンニン酸水溶液を噴霧して羽毛にタンニン酸を付着させ、そのまま乾燥(乾燥時間:15分くらい)させればよい。羽毛を撹拌しながらタンニン酸水溶液を噴霧することにより、羽毛に均一にタンニン酸を付着させることができるとともに、乾燥時間を短縮できる。なお、熱風の温度が低過ぎると乾燥に時間がかかり過ぎ、高過ぎるとタンニン酸の分解が起こるため好ましくない。 In the present invention, tannic acid may be attached to the feathers obtained as described above. Specifically, the tannic acid aqueous solution is sprayed on the feathers by spraying the feathers after dehydration in a hot air at 60 to 110 ° C., preferably 80 to 100 ° C. with stirring using a stirring rod or a stirring blade. And then dried as it is (drying time: about 15 minutes). By spraying the tannic acid aqueous solution while stirring the feathers, tannic acid can be uniformly attached to the feathers and the drying time can be shortened. If the temperature of the hot air is too low, drying takes too much time, and if it is too high, tannic acid will decompose, which is not preferable.
本発明においては、前記タンニン酸水溶液の濃度が0.3〜20質量%であることが好ましく、0.5〜2.0質量%であることがより好ましい。 In this invention, it is preferable that the density | concentration of the said tannic acid aqueous solution is 0.3-20 mass%, and it is more preferable that it is 0.5-2.0 mass%.
また、原料羽毛100質量部に対して、前記タンニン酸水溶液を3〜100質量部噴霧することが好ましく、40〜80質量部噴霧することがより好ましい。 Moreover, it is preferable to spray 3-100 mass parts of said tannic acid aqueous solution with respect to 100 mass parts of raw material feathers, and it is more preferable to spray 40-80 mass parts.
タンニン酸水溶液の濃度や噴霧量が上記範囲外であると、羽毛の嵩高性が損われたり、充分なアレルギー抗原不活化活性能を付与できないので好ましくない。 If the concentration or spray amount of the tannic acid aqueous solution is outside the above range, the bulkiness of the feathers is impaired, and sufficient allergen antigen inactivating activity ability cannot be imparted.
更に、本発明においては、タンニン酸と他の抗菌剤を併用することもできる。これにより、抗アレルギー性や防臭性を高めることができる。 Furthermore, in the present invention, tannic acid and other antibacterial agents can be used in combination. Thereby, antiallergic property and deodorizing property can be improved.
上記抗菌剤としては、公知の抗菌剤を用いることができるが、安全性の面等からキトサンが好ましく用いられるが、他に、糖質やトロポロン、ヒノキチオール、エステル、テルペンに分類される天然有機系抗菌剤を用いることもできる。その他、銀、銅、亜鉛に代表される金属塩等に分類される無機系抗菌剤や、ビグアナイド、カーバニリド、両性界面活性剤、カルボン酸、アルコール等に分類される有機系抗菌剤を用いることもできる。併用する抗菌剤は、抗菌剤を含む溶液を別途調製して羽毛に噴霧してもよいが、工程を簡略化できる点から、タンニン酸水溶液に添加して用いることが好ましい。例えば、抗菌剤としてキトサンを用いる場合は、所定濃度のタンニン酸水溶液に、濃度0.5〜10質量%、好ましくは1〜3質量%となるようにキトサンを添加して用いればよい。 As the antibacterial agent, known antibacterial agents can be used, but chitosan is preferably used from the viewpoint of safety, etc., but other natural organic types classified into carbohydrates, tropolone, hinokitiol, esters and terpenes Antibacterial agents can also be used. In addition, inorganic antibacterial agents classified into metal salts such as silver, copper, and zinc, and organic antibacterial agents classified into biguanides, carbanilides, amphoteric surfactants, carboxylic acids, alcohols, etc. may be used. it can. The antibacterial agent used in combination may be prepared separately and sprayed onto the feathers, but it is preferably added to the tannic acid aqueous solution from the viewpoint that the process can be simplified. For example, when chitosan is used as the antibacterial agent, chitosan may be added to a tannic acid aqueous solution having a predetermined concentration so that the concentration is 0.5 to 10% by mass, preferably 1 to 3% by mass.
なお、タンニン酸や抗菌剤と羽毛との結合性を高め、耐洗濯性等を向上させるために、ウレタン系、シリコン系、ポリエチレン系等の公知のバインダーを併用することもできる。 A known binder such as urethane, silicon, or polyethylene may be used in combination in order to enhance the binding between tannic acid or antibacterial agent and feathers and improve the washing resistance.
上記のようにして、羽毛にタンニン酸を付着させて充分に乾燥した後、羽毛温度を下げ、微細な埃等を取り除くことで、アレルギー抗原不活化活性能を有する加工羽毛を得ることができる。 As described above, tannic acid is attached to the feathers and dried sufficiently, and then the feather temperature is lowered and fine dust and the like are removed to obtain a processed feather having allergen antigen inactivating activity.
このようにして得られた加工羽毛は、布団、枕、クッション、ダウンジャケット、寝袋の他、羽毛を使用した様々な羽毛製品に使用することができるが、特にアレルギー患者用の製品に好ましく使用することができる。 The processed feathers obtained in this way can be used for futons, pillows, cushions, down jackets, sleeping bags, as well as various feather products using feathers, but are particularly preferably used for products for allergic patients. be able to.
以下、実施例を挙げて本発明を具体的に説明するが、これらの実施例は本発明の範囲を限定するものではない。 EXAMPLES Hereinafter, although an Example is given and this invention is demonstrated concretely, these Examples do not limit the scope of the present invention.
<実施例1>
常法にしたがって洗浄した原料羽毛(中国産ホワイトグースダウン)20kgを、撹拌羽根を有する乾燥機に入れて、80℃の熱風を送りながら撹拌しつつ、表1に示す各種濃度のタンニン酸水溶液(加水分解型ガロタンニン、商品名「タンニン酸AL」、富士化学工業製)を所定量噴霧して、充分に乾燥させた後冷却して、加工羽毛(サンプル1〜6及び対照サンプル)を得た。
<Example 1>
20 kg of raw material feathers (Chinese white goose down) washed according to a conventional method is placed in a dryer having stirring blades and stirred while sending hot air at 80 ° C., and tannic acid aqueous solutions having various concentrations shown in Table 1 ( A predetermined amount of hydrolyzed gallotannin, trade name “tannic acid AL”, manufactured by Fuji Chemical Industry Co., Ltd. was sprayed, sufficiently dried and then cooled to obtain processed feathers (samples 1 to 6 and a control sample).
<試験例1>
上記実施例1で得られた各サンプルを用いて、嵩高性の測定及びダニ抗原(Der P1)の不活化試験を行った。
<Test Example 1>
Using each sample obtained in Example 1, the bulkiness measurement and the mite antigen (Der P1) inactivation test were performed.
(1)嵩高性の測定
嵩高性の測定は、JIS L-1908及び日羽協B法(前処理)にしたがって行った。その結果を表2に示す。
(1) Measurement of bulkiness The bulkiness was measured according to JIS L-1908 and the Hiwa Kyo B method (pretreatment). The results are shown in Table 2.
表2から、噴霧するタンニン酸水溶液の濃度が高くなるにつれて、嵩高性が低下する傾向にあるが、本願で規定するタンニン酸水溶液の濃度では、充分な嵩高性を有していることが分かる。 From Table 2, it can be seen that the bulkiness tends to decrease as the concentration of the sprayed tannic acid aqueous solution increases, but the tannic acid aqueous solution concentration specified in the present application has sufficient bulkiness.
(2)ダニ抗原(Der P1)の不活化試験
ダニ抗原(Der P1)を溶解した水溶液2mlに、上記各サンプル(0.2g)を浸漬し、24時間反応(3時間振とう、18〜20時間静置)した。反応終了後、各サンプルを浸漬した水溶液中のダニ抗原の抗原活性をELISA法にて測定した。
(2) Inactivation test of mite antigen (Der P1) Each sample (0.2 g) was immersed in 2 ml of an aqueous solution in which mite antigen (Der P1) was dissolved, and reacted for 24 hours (shaking for 3 hours, 18 to 20). (Time standing). After completion of the reaction, the antigen activity of the mite antigen in the aqueous solution in which each sample was immersed was measured by ELISA.
ELISA法は、抗Der P1抗体(LCDアレルギー研究所社製)、ビオチン標識抗Der P1抗体(LCDアレルギー研究所社製)、酵素(β−ガラクトシダーゼ)標識ストレプトアビジン(SIGMA社製)を用意し、常法にしたがって行った。すなわち、プレートの各ウエルを抗Der P1抗体でコーティングした後、各サンプルを浸漬した水溶液を添加し、プレート上に捕捉したダニ抗原に、ビオチン標識抗Der P1抗体を反応させた。洗浄後、酵素標識ストレプトアビジンを反応させて洗浄した後、β−ガラクトピクノシド(基質)を加えて、各ウエルの酵素活性を吸光度(波長415nm)によって測定した。そして、標準抗原を加えたウエルの吸光度から標準曲線を作成して各水溶液中のダニ抗原量を求めた。 For the ELISA method, an anti-Der P1 antibody (manufactured by LCD Allergy Laboratories), a biotin-labeled anti-Der P1 antibody (manufactured by LCD Allergy Laboratories), and an enzyme (β-galactosidase) -labeled streptavidin (manufactured by SIGMA) are prepared. It was carried out according to the usual method. That is, after each well of the plate was coated with anti-Der P1 antibody, an aqueous solution in which each sample was immersed was added, and biotin-labeled anti-Der P1 antibody was reacted with the mite antigen captured on the plate. After washing, enzyme-labeled streptavidin was reacted and washed, β-galactopicnoside (substrate) was added, and the enzyme activity of each well was measured by absorbance (wavelength 415 nm). Then, a standard curve was created from the absorbance of the wells to which the standard antigen was added, and the amount of mite antigen in each aqueous solution was determined.
なお、抗原不活化率(%)は、羽毛自体の測定系への影響を除くために、タンニン酸を加工しない羽毛を用いた場合の抗原Der p1の残存量の測定値を基準にして、その抗原不活化率(%)により算出した。
その結果を表3に示す。
In addition, the antigen inactivation rate (%) is determined based on the measured value of the residual amount of antigen Der p1 when feathers that do not process tannic acid are used in order to eliminate the influence on the measurement system of the feathers themselves. It calculated by the antigen inactivation rate (%).
The results are shown in Table 3.
表3から、噴霧するタンニン酸水溶液の濃度が高くなるにつれて、抗原不活化率も高くなっていることが分かる。 From Table 3, it can be seen that the antigen inactivation rate increases as the concentration of the tannic acid aqueous solution to be sprayed increases.
以上の結果から、本願で規定する所定濃度のタンニン酸水溶液を所定量噴霧することにより、嵩高性を損うことなく、充分なアレルゲン不活化活性能を付与した加工羽毛が得られることが分かる。 From the above results, it can be seen that by spraying a predetermined amount of a tannic acid aqueous solution having a predetermined concentration specified in the present application, a processed feather having sufficient allergen inactivation activity ability can be obtained without impairing bulkiness.
<実施例2>
常法にしたがって洗浄した原料羽毛(中国産ホワイトグースダウン)20kgを、撹拌羽根を有する乾燥機に入れて、80℃の熱風を送りながら撹拌しつつ、タンニン酸濃度1.2質量%の水溶液(加水分解型ガロタンニン、商品名「タンニン酸AL」、富士化学工業製)を、対羽毛量100%の量で噴霧して、充分に乾燥させた後冷却して、加工羽毛(サンプル3)を得た。
<Example 2>
20 kg of raw material feathers (Chinese white goose down) washed according to a conventional method is put into a dryer having a stirring blade and stirred while sending hot air at 80 ° C., and an aqueous solution having a tannic acid concentration of 1.2% by mass ( Hydrolyzed gallotannin, trade name “Tannic acid AL”, manufactured by Fuji Chemical Co., Ltd.) is sprayed in an amount of 100% against feathers, dried sufficiently and cooled to obtain processed feathers (sample 3). It was.
また、上記羽毛20kgを、タンニン酸濃度1.0質量%の水溶液(加水分解型ガロタンニン、商品名「タンニン酸AL」、富士化学工業製)に、常温にて30分間浸漬して取り出し、充分に乾燥させた後冷却して、加工羽毛(サンプル7)を得た。 Further, 20 kg of the feathers described above were immersed in an aqueous solution having a tannic acid concentration of 1.0% by mass (hydrolyzable gallotannin, trade name “tannic acid AL”, manufactured by Fuji Chemical Industry Co., Ltd.) for 30 minutes at room temperature. After drying, it was cooled to obtain a processed feather (sample 7).
更に、未加工の原料羽毛を対照とした。 Furthermore, raw material feathers were used as a control.
<試験例2>
上記実施例2で得られた各サンプルを用いて、上記試験例1と同様に嵩高性の測定及びダニ抗原(Der P1)の不活化試験を行った。嵩高性の測定結果を下記表4に示し、ダニ抗原(Der P1)の不活化試験結果を下記表5に示す。
<Test Example 2>
Using each sample obtained in Example 2, the bulkiness measurement and the mite antigen (Der P1) inactivation test were performed in the same manner as in Test Example 1. The bulkiness measurement results are shown in Table 4 below, and the mite antigen (Der P1) inactivation test results are shown in Table 5 below.
表4から、タンニン酸に浸漬させて加工したサンプル7の羽毛では、対照に比べて嵩高性が低下したが、タンニン酸を噴霧して加工したサンプル3の羽毛では、対照と変らない傘高性が得られることが分かる。 From Table 4, the feathers of sample 7 processed by immersing in tannic acid showed lower bulkiness than the control, but the feathers of sample 3 processed by spraying tannic acid did not change from the control. It can be seen that
表5から、タンニン酸に浸漬させて加工したサンプル7の羽毛よりも、タンニン酸を噴霧して加工したサンプル3の羽毛の方が、ダニ抗原の不活化率は高くなることが分かる。 From Table 5, it can be seen that Sample 3 feather processed by spraying tannic acid has a higher mite antigen inactivation rate than Sample 7 feather processed by immersing in tannic acid.
本発明の加工羽毛の製造方法は、人体に対する安全性の高いタンニン酸を、羽毛の嵩高性を低下させることなく羽毛に結合させて、アレルギー抗原の不活性化能を付与できるので、人体に直接触れる寝装品をはじめとする様々な羽毛製品に適用できる。 The method for producing processed feathers of the present invention can impart tannic acid, which is highly safe to the human body, to the feathers without reducing the bulkiness of the feathers, and thus can impart inactivation ability of allergic antigens. Applicable to various feather products such as bedding items to touch.
