【発明の属する技術分野】
本発明は、血行を良くし、かぶれを抑制する効果のある繊維および繊維製品に関するものであり、紙オムツ、生理用ナプキン、包帯、ガーゼ等の衛生材料、使い捨て肌着、ウェットティッシュ、化粧パフ等の対人用ワイパーなどに好適な繊維および繊維製品に関する。
【0002】
【従来の技術】
従来より、紙オムツや生理用ナプキンなどのように人体に接触する繊維製品において、かぶれが重要視されており、特に、オムツかぶれの要因としては、汚物によって発生するカンジダ菌など種々の細菌の繁殖、オムツの通気性(汗などの蒸れ)、表面紙との摩擦、尿、便との接触による化学反応などが考えられている。中でも、細菌の繁殖が重要視され、これらの繁殖を抑制してオムツかぶれを防止しようする試みがなされている。
【0003】
例えば、特開昭61−28078号公報には、クマザサとハトムギとその他の植物エキス油を布地や紙製品に塗布したものが提案されている。また、特公昭63−54013号公報、特開昭63−175117号公報、特開平1−250413号公報には、ゼオライトに担持させた抗菌性金属のイオン解離により抗菌性を付与した繊維、並びに繊維製品が提案されている。さらに、その他にもビグアナイト誘導体、有機シリコン系第4級アンモニウム塩を用いて抗菌性を付与したものもある。そして、上記以外にも人体への影響を考え、天然物より抽出した抗菌剤の使用例もある。特開平5−5274号公報には、キチンの脱アセチル化物を、特開平9−108261号公報には、グリチルリチンやフィトンチドをシクロデキストリンに包接化したものを用いて、抗菌、抗かびおよび防臭効果によってオムツかぶれを抑制しようとしたものが提案されている。
【0004】
【発明が解決しようとする課題】
しかしながら、上記繊維および繊維製品には以下の問題点が挙げられる。例えば、特開昭61−28078号公報では、天然物より抽出されたトコフェロール同族体の大半(約60〜80%以上)はγ型であり、実際、生体内における生物活性を有するα型は多くとも20%程度であり、かぶれの抑制には十分とはいえない。さらに、油脂(リノール酸)を含むことで光(紫外線)などにより酸化劣化が生じ、皮膚の脂質の酸化、過酸化脂質を誘発する恐れがある。また、抗菌性物質を含有する繊維製品は、細菌などの繁殖を抑制する効果があるとしても、本質的なオムツかぶれの原因についての対策が講じられておらず、その効果は十分とはいえない。
【0005】
本発明はかかる実情を鑑みてなされたものであり、血行を良くし、かぶれに効果のある、紙オムツ、生理用ナプキン、包帯、ガーゼ等の衛生材料、使い捨て肌着、ウェットティッシュ、化粧パフ等の対人用ワイパーなどに好適な繊維および繊維製品を提供することを目的とする。
【0006】
【課題を解決するための手段】
本発明の繊維は、単繊維表面の少なくとも一部にトコフェロール同族体が付着している繊維において、該トコフェロール同族体のうち、α型トコフェロールが繊維100重量部に対して0.01〜0.5重量部付着していることを特徴とする。かかる構成を採ることにより、外的要因でオムツかぶれを抑制するのではなく、人体の内面すなわち血行を促進し、かつ皮膚表面の酸化劣化を抑制することによって、内的にオムツかぶれを抑制できることが判り、本発明に至った。
【0007】
本発明の繊維において、トコフェロール同族体のうち、α型トコフェロール/残りのトコフェロール同族体の重量比は、2/8〜7/3であることが望ましい。
【0008】
本発明の繊維において、トコフェロール同族体以外の親水性繊維処理剤は、繊維100重量部に対して0.1〜1重量部付着していることが望ましい。
【0009】
そして、本発明の繊維からなる繊維製品は、人体の血行を促進し、かつ皮膚表面の酸化劣化が抑制されて、オムツなどのかぶれ抑制に寄与する。
以下、本発明の内容を具体的に説明する。
【0010】
【発明の実施の形態】
本発明の繊維とは、繊維形態を有するものであれば、特に限定されず、例えば、レーヨン等の再生繊維、アクリル系繊維、ナイロン6、ナイロン66等のポリアミド系繊維、ポリエチレンテレフタレート、ポリブチレンテレフタレート等のポリエステル系繊維、ポリエチレン、ポリプロピレン等のポリオレフィン系繊維等の長繊維、あるいは短繊維のことを示し、繊維形状等も特に限定されず、単一繊維、芯鞘型複合繊維、分割型複合繊維、異形断面を有する繊維、中空繊維等をいずれであってもよい。
【0011】
例えば、本発明の繊維を衛生材料用途の表面シートに使用する場合であれば、ポリプロピレン/ポリエチレン、ポリエチレンテレフタレート/ポリエチレン、ポリプロピレン/エチレン−プロピレン共重合体、ポリエチレンテレフタレート/エチレン−プロピレン共重合体などの組合せからなる熱接着性芯鞘型複合繊維や分割型複合繊維などが好適である。
【0012】
また、本発明の繊維における繊度も特に限定されるものではなく、用途に応じて適宜設定すれば良いが、表面シートとして用いる場合であれば、風合いを重視し、2〜6dtexが好ましい。
【0013】
本発明における繊維製品は、不織布、網状物、編織物など単繊維からなる形態を有するものであればいずれであってもよく、トコフェロール同族体を予め付着させた繊維から繊維製品を得てもよいし、未処理の単繊維を繊維製品に加工した後に、繊維製品を構成する単繊維の少なくとも一部にトコフェロール同族体が付着するように処理してもよい。繊維製品が例えば不織布の場合、構成する繊維ウェブの形態としては、特に限定されるものではなく、ステープル繊維からなるパラレルウェブやクロスウェブ、セミランダムウェブ、連続フィラメントからなる長繊維ウェブ、短繊維を湿式抄紙したウェブ、エアレイウェブ、あるいはメルトブロー不織布等を任意に使用することができる。不織布の風合い、柔軟性を重視する場合であれば、ステープル繊維からなる繊維ウェブが好ましい。
【0014】
不織布の加工法においても特に限定されず、熱風吹き付け法、熱ロール法などからなるサーマルボンド法、スパンボンド法、湿式抄紙法、ニードルパンチ法、スパンレース法など公知の方法を採ることができ、任意に選択すればよい。特に、衛生材料(特に乳幼児のオムツ)の表面シートであれば、肌との摩擦によるこすれを考慮し、風合いのよいサーマルボンド不織布が一般的に用いられており、それに用いられる繊維は、熱接着性芯鞘型複合繊維が好適である。また、スパンボンド法、湿式抄紙法、スパンレース法などにおいては、製造工程上、不織布作製後、後加工にて調製したトコフェロール同族体をスプレーまたは含浸するとよい。
【0015】
繊維ウエブの目付は、特に限定されるものではないが、例えば衛生材料の表面シートであれば、目付15〜40g/m2程度が好ましい。
【0016】
そして、前記繊維および繊維製品において、単繊維表面の少なくとも一部に付着しているトコフェロールは、一般に大豆油、菜種油より抽出、精製、濃縮して得られるものであって、α型、β型、γ型、およびδ型のトコフェロール同族体によって形成される。そして、本発明においては、トコフェロール同族体のうち、α型トコフェロールが繊維100重量部に対して0.01〜0.5重量部付着していることが好ましい。α型トコフェロールの付着量が0.01重量部未満であると、かぶれ抑制が十分とはいえず、0.5重量部を超えても有意差は確認できず、高コストとなり、機能面とのバランスにおいて不利となるからである。
【0017】
また、残りの同族体であるβ型、γ型およびδ型トコフェロールも含むことで繊維処理剤の酸化を抑制し、腐敗の防止にもつながり、繊維処理剤のランニングコストの低減することができ、都合がよい。本発明においては、トコフェロール同族体のうち、α型トコフェロール/残りのトコフェロール同族体の重量比は、2/8〜7/3であることが好ましい。より好ましくは、3/7〜5/5である。重量比が2/8未満であると、自然界の植物油中に含まれる一般的な割合であり、α型トコフェロールの割合が少なくなると、生物活性が小さくなり、重量比が7/3を超えると、生体外すなわち繊維処理剤などに抗酸化阻害が起きる恐れがあり、コスト的にも割高なものとなるからである。
【0018】
さらに、残りトコフェロールのうち、γ型トコフェロールやδ型トコフェロールが繊維処理剤の酸化抑制に特に効果があり、α型トコフェロール/{γ型トコフェロールおよび/またはδ型トコフェロール}/残りのトコフェロール同族体の重量比は、2/7/1〜7/3/0であることが好ましい。
【0019】
そして、ビタミンEの主成分であるトコフェロール同族体以外にも、別の薬剤を添加してもよい。例えば、ビタミンE以外のビタミンA、ビタミンCなどのビタミン剤が挙げられ、特にビタミンAは、トコフェロール同族体の吸収効率を高めることができ好適である。
【0020】
次に、本発明の繊維および繊維製品の製造方法について説明する。まず、トコフェロール同族体(α型、β型、γ型、およびδ型)を所定の割合に調製する。そして、調製されたトコフェロール同族体は、油状であるため、公知の乳化剤で乳化することによって通常の繊維処理剤に添加でき、容易に溶解することができる。これにより、従来の化学繊維、合成繊維の製造工程において、極めて容易に単繊維表面に所望のトコフェロール同族体を付着させることができる。このとき用いられる繊維処理剤は、いずれであってもよいが、親水性の繊維処理剤であると、例えば、吸収性物品の表面シートに使用した場合、液体透過性に優れ、液体を吸収体に迅速に移行させることができる点で優れている。親水性繊維処理剤の付着量は、繊維100重量部に対して0.1〜1重量部であることが好ましい。付着量が0.1重量部未満であると、静電気が発生し易く、工程性に劣るだけでなく、十分な親水性能が得られない。付着量が1重量部を超えると、カード工程での開繊不良が発生し易いだけでなく、コスト高となる。
【0021】
そして、トコフェロール同族体は、繊維製造時の延伸後、あるいは通常の繊維処理剤を付着または未処理の繊維を得たのち繊維製品へ加工した後、スプレーおよび/または含浸させることによって付着させることができる。トコフェロール同族体は、熱安定性に優れており、繊維処理剤付着後の乾燥工程や熱接着性繊維として用いたときの不織布加工温度領域でも安定なことから、繊維製造工程内での付着処理がコスト面でも優位である。
【0022】
【実施例】
以下、本発明の内容について実施例を挙げて説明する。
[実施例1]
まず、仕上げ処理油剤槽に燐酸エステルカリウム塩を主体とする親水性繊維処理剤が純分1.5%になるように調製した。そして、重量比でα型/β型/γ型/δ型=50/2/45/3となるように調製、乳化されたトコフェロール同族体を仕上げ処理油剤槽に添加し、トコフェロール同族体の純分が0.1%になるように調製し、準備した。
【0023】
次に、芯成分にポリエチレンテレフタレート、鞘成分に高密度ポリエチレンを容積比で1/1の割合で配した円形芯鞘型ノズルを用いて溶融紡糸を行い、繊度6dtexの未延伸糸を得た。次いで、未延伸糸を80℃の温水中で3倍に延伸し、連続して延伸糸を予め調製した仕上げ処理油剤槽に浸漬させ、スタフィンボックス型クリンパーにて機械捲縮を15山/25mmの割合で付与した。これを熱風乾燥機にて110℃で15分間乾燥し、水分を除去した後に、51mmの繊維長に切断して、繊度2.2dtexのステープル繊維を得た。
【0024】
得られたステープル繊維を100g採取し、含まれる油分およびトコフェロール同族体をクロロホルムとメタノールの1:1混合溶剤にて抽出し、液体クロマトグラフによりトコフェロール同族体の総付着量および各同族体の付着量を同定した。チャートのピーク面積より算出した結果、トコフェロール同族体の単繊維表面への総付着量は、0.05重量部であった。そして、各同族体の付着率はα型、γ型それぞれ0.03重量部、0.02重量部であった。β型、δ型については、微量であったため検出するには至らなかった。
【0025】
[比較例1]トコフェロール同族体の割合をα型/γ型=90/10とし、さらに仕上げ処理油剤槽でのトコフェロール同族体の純分を0.8%とした以外は実施例1と同様の方法でステープル繊維を得た。トコフェロール同族体の付着量を測定した結果、α型、γ型それぞれ、0.30重量部、0.03重量部であった。
【0026】
[比較例2]トコフェロール同族体を用いないこと以外は、実施例1と同様の方法でステープル繊維を得た。
【0027】
[比較例3]トコフェロール同族体として、調製を行わずに大豆油に含まれているそのままの割合、α型/β型/γ型/δ型=10/0/60/30とした以外は、実施例1と同様に方法でステープル繊維を得た。トコフェロール同族体の付着量を測定した結果、α型、β型、γ型、およびδ型それぞれ、0.005重量部、0、0.035重量部、0.01重量部であった。
【0028】
実施例、比較例で得たステープル繊維をパラレルカードにて目付20g/m2の繊維ウェブを作製した後、熱風加工機にて140℃で5秒間熱処理を施し、サーマルボンド不織布となした。各不織布を紙オムツの表面シートとして評価すると、特に実施例1において、皮膚かぶれが起きることなく、十分な効果が得られた。しかも実施例1は、α型トコフェロール/γ型およびδ型トコフェロール/他のトコフェロールを50/48/2の割合で含有することにより、繊維処理剤を長期間保管していても、酸化が抑制されて腐敗することはなかった。
【0029】
【発明の効果】
本発明の繊維および繊維製品は、単繊維表面の少なくとも一部に、α型トコフェロールが繊維100重量部に対して0.01〜0.5重量部付着していることにより、人体の毛細血管を拡張し、血行促進を促すことができ、また、抗酸化作用および過酸化脂質の抑制により、皮膚中の脂質の酸化に伴う皮膚表面、肌荒れの防止を促すことができるので、紙オムツ、生理用ナプキンなどの衛生材料のように人体に直接接触したときのかぶれの抑制に効果がある。
そして、本発明の繊維および繊維製品は、紙オムツ、生理用ナプキン、包帯、ガーゼ等の衛生材料、使い捨て肌着、ウェットティッシュ、化粧パフ等の対人用ワイパーなどに好適である。[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a fiber and a fiber product that have an effect of improving blood circulation and suppressing rash, such as sanitary materials such as paper diapers, sanitary napkins, bandages, gauze, disposable underwear, wet tissue, cosmetic puffs, etc. The present invention relates to fibers and fiber products suitable for personal wipers and the like.
[0002]
[Prior art]
Conventionally, rashes have been regarded as important in textile products that come into contact with the human body, such as paper diapers and sanitary napkins. In particular, the cause of diaper rashes is the growth of various bacteria such as Candida spp. Diaper breathability (sweat such as sweat), friction with surface paper, urine, chemical reaction due to contact with stool, etc. are considered. Above all, the propagation of bacteria is regarded as important, and attempts have been made to prevent diaper rash by suppressing these propagations.
[0003]
For example, Japanese Patent Application Laid-Open No. 61-28078 proposes a cloth or paper product coated with Kumazasa, pearl barley and other plant extract oils. JP-B 63-54013, JP-A 63-175117, and JP-A 1-250413 disclose fibers imparted with antibacterial properties by ion dissociation of an antibacterial metal supported on zeolite, and fibers. A product has been proposed. In addition, antibacterial properties are imparted using biguanite derivatives and organic silicon quaternary ammonium salts. In addition to the above, there are also examples of using antibacterial agents extracted from natural products in consideration of effects on the human body. JP-A-5-5274 discloses a deacetylated product of chitin, and JP-A-9-108261 uses an inclusion of glycyrrhizin or phytoncide in cyclodextrin to provide antibacterial, antifungal and deodorizing effects. Has proposed to control diaper rash.
[0004]
[Problems to be solved by the invention]
However, the following problems are mentioned in the above-mentioned fibers and fiber products. For example, in Japanese Patent Application Laid-Open No. 61-28078, most of the tocopherol homologues extracted from natural products (about 60 to 80% or more) are γ type, and in fact, there are many α types having biological activity in vivo. Both are about 20%, which is not sufficient for suppressing rash. Furthermore, by containing fats and oils (linoleic acid), oxidative degradation may occur due to light (ultraviolet rays) and the like, which may induce oxidation of lipids in the skin and lipid peroxides. In addition, even if the textile products containing antibacterial substances have the effect of suppressing the growth of bacteria, etc., no measures have been taken for the cause of essential diaper rash, and the effect is not sufficient. .
[0005]
The present invention has been made in view of such circumstances, such as paper diapers, sanitary napkins, bandages, gauze and other sanitary materials, disposable underwear, wet tissues, cosmetic puffs, etc. that improve blood circulation and are effective against rashes. It is an object of the present invention to provide fibers and fiber products suitable for interpersonal wipers and the like.
[0006]
[Means for Solving the Problems]
The fiber of the present invention is a fiber in which a tocopherol homologue is attached to at least a part of the surface of a single fiber. Among the tocopherol homologues, α-type tocopherol is 0.01 to 0.5 with respect to 100 parts by weight of the fiber. It is characterized by adhering to a weight part. By adopting such a configuration, it is possible to suppress diaper rash internally by promoting the inner surface of the human body, that is, blood circulation, and suppressing oxidative deterioration of the skin surface, rather than suppressing diaper rash due to external factors. As a result, the present invention has been achieved.
[0007]
In the fiber of the present invention, among the tocopherol homologues, the α-type tocopherol / remaining tocopherol homologue weight ratio is preferably 2/8 to 7/3.
[0008]
In the fiber of the present invention, it is desirable that the hydrophilic fiber treating agent other than the tocopherol homolog is attached in an amount of 0.1 to 1 part by weight with respect to 100 parts by weight of the fiber.
[0009]
And the fiber product which consists of a fiber of this invention accelerates | stimulates the blood circulation of a human body, the oxidative degradation of the skin surface is suppressed, and it contributes to suppression of a rash, such as a diaper.
The contents of the present invention will be specifically described below.
[0010]
DETAILED DESCRIPTION OF THE INVENTION
The fiber of the present invention is not particularly limited as long as it has a fiber form. For example, regenerated fiber such as rayon, acrylic fiber, polyamide fiber such as nylon 6, nylon 66, polyethylene terephthalate, polybutylene terephthalate. Polyester fiber such as polyethylene fiber, long fiber such as polyolefin fiber such as polyethylene and polypropylene, or short fiber, and the fiber shape is not particularly limited. Single fiber, core-sheath type composite fiber, split type composite fiber Any of a fiber having a modified cross section, a hollow fiber and the like may be used.
[0011]
For example, when the fiber of the present invention is used for a surface sheet for sanitary materials, polypropylene / polyethylene, polyethylene terephthalate / polyethylene, polypropylene / ethylene-propylene copolymer, polyethylene terephthalate / ethylene-propylene copolymer, etc. A heat-adhesive core-sheath type composite fiber or a split type composite fiber made of a combination is suitable.
[0012]
Further, the fineness of the fiber of the present invention is not particularly limited, and may be appropriately set according to the use. However, when used as a surface sheet, the texture is emphasized, and 2 to 6 dtex is preferable.
[0013]
The fiber product in the present invention may be any fiber product as long as it has a form composed of single fibers such as a nonwoven fabric, a net-like material, and a knitted fabric, and a fiber product may be obtained from a fiber to which a tocopherol homolog is previously attached. And after processing an untreated single fiber into a fiber product, you may process so that a tocopherol homologue may adhere to at least one part of the single fiber which comprises a fiber product. When the fiber product is, for example, a non-woven fabric, the form of the constituent fiber web is not particularly limited, and includes a parallel web composed of staple fibers, a cross web, a semi-random web, a long fiber web composed of continuous filaments, and a short fiber. Wet paper-made webs, air laid webs, melt blown nonwoven fabrics and the like can be arbitrarily used. If emphasis is placed on the texture and flexibility of the nonwoven fabric, a fiber web made of staple fibers is preferred.
[0014]
It is not particularly limited in the processing method of the nonwoven fabric, and it is possible to adopt a known method such as a thermal bond method including a hot air spray method, a hot roll method, a spun bond method, a wet paper making method, a needle punch method, a spun lace method, Any selection may be made. In particular, for surface sheets of sanitary materials (especially infant diapers), thermal bond nonwoven fabrics with good texture are generally used in consideration of rubbing due to friction with the skin. The core-sheath type composite fiber is suitable. In the spunbond method, wet papermaking method, spunlace method, and the like, it is preferable to spray or impregnate the tocopherol homologue prepared by post-processing after manufacturing the nonwoven fabric in the manufacturing process.
[0015]
The basis weight of the fiber web is not particularly limited. For example, in the case of a sanitary material surface sheet, a basis weight of about 15 to 40 g / m 2 is preferable.
[0016]
In the fibers and fiber products, the tocopherol adhering to at least a part of the surface of the single fiber is generally obtained by extraction, purification, and concentration from soybean oil or rapeseed oil, and α-type, β-type, It is formed by γ-type and δ-type tocopherol homologues. And in this invention, it is preferable that (alpha) -type tocopherol adheres 0.01-0.5 weight part with respect to 100 weight part of fibers among tocopherol homologues. If the adhesion amount of α-type tocopherol is less than 0.01 parts by weight, rash suppression cannot be said to be sufficient, and if it exceeds 0.5 parts by weight, a significant difference cannot be confirmed, resulting in high costs and This is a disadvantage in balance.
[0017]
In addition, the remaining homologues β-type, γ-type, and δ-type tocopherols can be used to suppress the oxidation of the fiber treatment agent and prevent spoilage, thereby reducing the running cost of the fiber treatment agent. convenient. In the present invention, among the tocopherol homologues, the weight ratio of α-type tocopherol / remaining tocopherol homologues is preferably 2/8 to 7/3. More preferably, it is 3/7 to 5/5. When the weight ratio is less than 2/8, it is a general ratio contained in natural vegetable oil. When the ratio of α-type tocopherol decreases, the biological activity decreases, and when the weight ratio exceeds 7/3, This is because there is a risk that antioxidant inhibition will occur outside the living body, that is, in the fiber treatment agent, and the cost will be high.
[0018]
Further, among the remaining tocopherols, γ-type tocopherol and δ-type tocopherol are particularly effective in suppressing oxidation of the fiber treatment agent, and α-type tocopherol / {γ-type tocopherol and / or δ-type tocopherol} / weight of the remaining tocopherol homologue. The ratio is preferably 2/7/1 to 7/3/0.
[0019]
In addition to the tocopherol homologue which is the main component of vitamin E, another drug may be added. For example, vitamin A such as vitamin A and vitamin C other than vitamin E can be mentioned, and vitamin A is particularly preferable because it can increase the absorption efficiency of the tocopherol homologue.
[0020]
Next, the manufacturing method of the fiber and fiber product of this invention is demonstrated. First, tocopherol homologues (α-type, β-type, γ-type, and δ-type) are prepared at a predetermined ratio. And since the prepared tocopherol homologue is oily, it can be added to a normal fiber treatment agent by emulsifying with a known emulsifier, and can be easily dissolved. Thereby, in the manufacturing process of the conventional chemical fiber and synthetic fiber, a desired tocopherol homologue can be adhered to the single fiber surface very easily. The fiber treatment agent used at this time may be any, but when it is a hydrophilic fiber treatment agent, for example, when used for a surface sheet of an absorbent article, it has excellent liquid permeability and absorbs liquid. It is excellent in that it can be quickly transferred to. The adhesion amount of the hydrophilic fiber treatment agent is preferably 0.1 to 1 part by weight with respect to 100 parts by weight of the fiber. If the adhesion amount is less than 0.1 parts by weight, static electricity is easily generated, the processability is inferior, and sufficient hydrophilic performance cannot be obtained. If the amount of adhesion exceeds 1 part by weight, not only the opening failure in the card process is likely to occur, but also the cost increases.
[0021]
The tocopherol homologue can be attached by spraying and / or impregnating after drawing at the time of fiber production, or after processing a fiber product after attaching a normal fiber treatment agent or obtaining an untreated fiber. it can. Tocopherol homologues are excellent in thermal stability, and are stable even in the non-woven fabric processing temperature range when used as a drying process or heat-adhesive fiber after the fiber treatment agent is adhered. It is also superior in terms of cost.
[0022]
【Example】
Hereinafter, the contents of the present invention will be described with reference to examples.
[Example 1]
First, it prepared so that the hydrophilic fiber processing agent which has phosphoric acid ester potassium salt as a main component might be 1.5% of pure content in a finishing treatment oil agent tank. Then, tocopherol homologue prepared and emulsified so that α type / β type / γ type / δ type = 50/2/45/3 by weight ratio is added to the finishing oil tank, and The mixture was prepared so that the content was 0.1%.
[0023]
Next, melt spinning was performed using a circular core-sheath type nozzle in which polyethylene terephthalate as a core component and high-density polyethylene as a sheath component were arranged at a volume ratio of 1/1 to obtain an undrawn yarn having a fineness of 6 dtex. Next, the undrawn yarn is drawn 3 times in warm water at 80 ° C., and the drawn yarn is continuously immersed in a finishing oil tank prepared in advance, and 15 crimps / 25 mm of machine crimps by a staffin box type crimper. In the ratio of This was dried with a hot air dryer at 110 ° C. for 15 minutes to remove moisture, and then cut into a fiber length of 51 mm to obtain staple fibers having a fineness of 2.2 dtex.
[0024]
100 g of the obtained staple fiber was sampled, and the contained oil and tocopherol homologues were extracted with a 1: 1 mixed solvent of chloroform and methanol, and the total adhesion amount of the tocopherol homologues and the adhesion amount of each homologue were measured by liquid chromatography. Was identified. As a result of calculating from the peak area of the chart, the total adhesion amount of the tocopherol homologue to the single fiber surface was 0.05 part by weight. The adhesion rates of the homologues were 0.03 parts by weight and 0.02 parts by weight, respectively, α-type and γ-type. The β type and δ type were too small to be detected.
[0025]
[ Comparative Example 1 ] The same as Example 1 except that the ratio of the tocopherol homologue was α-type / γ-type = 90/10, and the pure content of the tocopherol homologue in the finishing oil tank was 0.8%. Staple fibers were obtained by the method. As a result of measuring the adhesion amount of the tocopherol homologue, they were 0.30 parts by weight and 0.03 parts by weight, respectively.
[0026]
[Comparative Example 2 ] Staple fibers were obtained in the same manner as in Example 1 except that the tocopherol homologue was not used.
[0027]
[Comparative Example 3 ] As a tocopherol homologue, the ratio as it is contained in soybean oil without preparation, α-type / β-type / γ-type / δ-type = 10/0/60/30, Staple fibers were obtained by the same method as in Example 1. As a result of measuring the adhesion amount of the tocopherol homologue, the α-type, β-type, γ-type, and δ-type were 0.005 parts by weight, 0, 0.035 parts by weight, and 0.01 parts by weight, respectively.

A fiber web having a basis weight of 20 g / m 2 was prepared from the staple fibers obtained in Examples and Comparative Examples using a parallel card, and then heat treated at 140 ° C. for 5 seconds with a hot air processing machine to obtain a thermal bond nonwoven fabric. When evaluating each nonwoven as a surface sheet of paper diaper, particularly Oite in Example 1, without occurs skin rash, sufficient effect was obtained. In addition, Example 1 contains α-type tocopherol / γ-type and δ- type tocopherol / other tocopherols in a ratio of 50/48/2, so that oxidation is suppressed even when the fiber treatment agent is stored for a long period of time. There was no corruption.

【The invention's effect】
The fiber and the fiber product of the present invention have an α-type tocopherol adhered to at least a part of the surface of a single fiber in an amount of 0.01 to 0.5 parts by weight with respect to 100 parts by weight of the fiber, thereby allowing the capillaries of the human body to be formed. It is possible to expand and promote blood circulation, and by preventing antioxidant and lipid peroxides, it can promote prevention of skin surface and rough skin due to oxidation of lipids in the skin. It is effective in suppressing rash when directly touching the human body like sanitary materials such as napkins.
The fibers and fiber products of the present invention are suitable for sanitary materials such as paper diapers, sanitary napkins, bandages, and gauze, and wipers for personal use such as disposable underwear, wet tissues, and cosmetic puffs.
