【発明の属する技術分野】
本発明は、花粉症の原因である花粉が付着しにくい花粉付着防止性に優れ、かつ構造物の内部に花粉が入り込みにくいことを特徴とする繊維構造物に関するものである。
【0002】
【従来の技術】
花粉症は一度発病すると、2月〜4月頃スギ花粉が飛散する時期にほぼ毎年発病し、なかなか完治しない病気でる。また、花粉症はスギ花粉だけでなくヒノキ、イネ、ブタクサ、ハンノキなど多くの花粉がアレルゲンになり患者の発生は通年化し、年により増減はあるものの、年々花粉の飛散量は増加する傾向にあり、その治療法も確立されていない。また、花を扱う農家や趣味で花に触れるガーデニング愛好者にとっては深刻な問題である。
【0003】
従来より、花粉症患者はなるべく花粉に触れない対策を取ってきた。花粉が飛散する時期に屋外に出ないことが最も効果があるがそれは困難であり、可能な対策として外出時に目、鼻、口に花粉がなるべく触れない様マスクやめがね、ゴーグル、帽子などで防御して来た。しかし外出後屋内に入ると、屋外で衣料に付着した花粉を持ち込むことになる。一旦屋内に花粉を持ち込むと屋外に出すことが難しいのが現状である。そこで、花粉が付着しにくく、繊維構造物の内部に花粉が入り込みにくい衣料が要求される。
【0004】
花粉を防止するものとして、スルホン酸塩、カルボン酸塩、リン酸塩、塩基性基またはホルミル基を有する化合物を含有し平行水分率が1%以上である花粉補足用繊維構造物が提案されている(特許文献1参照)。これらは花粉のアレルゲン物質を化学的に吸着するするものであり、これらを衣料として用いた場合、花粉を付着させたまま家の中に入ることになる。要するに家の中に花粉を持ち込むことになり花粉症の人にとっては返って好ましくないものである。
【0005】
また花粉を付着させないものとしては、有孔フィルム/シートにより形成された洗濯物用花粉防止カバーが提案されている(特許文献2参照)。これらは花粉が通過せず、水蒸気が通過する範囲の大きさの孔を有するフィルムを用いるものであるが、フィルムでるため一般衣料として用いた場合、ファッション性に欠け、またカーテンなどのインテリア用品としてもドレープ性がないなど汎用性に欠けるものであった。またフィルムは静電気が発生しやすく、花粉を呼び寄せやすくまた一旦付着した花粉はなかなか取れないという問題があった。
【0006】
衣料としては、導電性繊維を使用し静電気により花粉が付着しにくい衣料が商品化されているが、タテ糸とその隣接するタテ糸の隙間、ヨコ糸とその隣接するヨコ糸の隙間が大きく、花粉が衣服内に入り込む可能性があるものである。

【0009】
【発明が解決しようとする課題】
本発明は、かかる従来技術の背景に鑑み、花粉が付着しにくく、また落ちやすく繊維構造物内部に花粉が入り込みにくい上に、屋内に花粉を持ち込みにくい優れた繊維構造物を提供せんとするものである。
【0010】
【課題を解決するための手段】
本発明は、かかる課題を解決するために、次のような手段を採用するものである。すなわち、本発明の繊維構造物は、繊維構造物の少なくとも表面に制電性もしくは導電性を有する重合体からなる組成物が固着されており、かつ、該繊維構造物の該表面が、下記表面特性を全て満足することを特徴とするものである。
【0011】
(A)摩擦帯電圧が20℃×30%RH環境下で4KV以下である。
【0012】
(B)KES法による該表面の摩擦係数の平均偏差(MMD)のタテ方向、ヨコ方向の各々の値が0.04以下である。
【0013】
(C)表面粗さの平均偏差(SMD)のタテ方向、ヨコ方向の各々の値が4.0μm以下である。
【0014】
【発明の実施の形態】
本発明は、前記課題、つまり花粉が付着しにくく、また落ちやすく繊維構造物内部に花粉が入り込みにくい構造の繊維構造物で、かつ花粉が付着しにくいことが要求される外衣や布団干しカバーのような外の空間と接する用途としての必要機能について、鋭意検討し、静電気の発生による花粉の繊維構造物への吸着を抑制するとともに、布帛表面の粘着性が低く、かつ布帛表面が平滑である繊維構造物であって、さらに花粉は水分のあるところに吸着しやすいことから、水分を寄せ付けない疎水性、つまり撥水性を兼ね備えることが花粉付着防止性を大きく向上させることに着目して、繊維繊維構造物に、摩擦帯電圧や摩擦係数、さらに表面粗さが特定な範囲内であることを満たす、制電性もしくは導電性を有する重合体を、表面に固着してみたところ、初めて、かかる課題を一挙に解決することを究明したものである。
【0015】
一般に繊維布帛に発生する静電気を抑制するために使用される制電性を有する帯電防止剤は、繊維表面に固着させた場合、帯電防止剤自身が空気中の湿気を吸湿し水分を保有することにより電気の伝導性を向上させ、静電気の発生を抑制するものが多い。このように湿度依存性が高い帯電防止剤つまり吸湿することにより制電性を有する重合体は、乾燥している時は固形物として繊維表面に固着しているが、吸湿することで重合体が液化し、重合体表面が粘着性を帯びる。このような現象は浮遊している花粉のような浮遊粒子が物理的衝撃などにより付着した場合、かかる粘着性が花粉をつかんで離しにくく、布帛表面に付きやすくなる。結果的にかかる繊維構造物からなる衣服を着用した場合に屋内に花粉を持ち込む原因となる。
【0016】
本発明はの制電性もしくは導電性を有する重合体としては、20℃×65%RH環境下で液化しないものが好ましく使用される。
【0017】
すなわち、かかる制電性もしくは導電性を有する重合体を、ポリエステルフィルム上にコーティングし、絶乾した後、20℃×65%RH環境下に放置しても、湿度依存性が低く、重合体表面が液化しないものである。つまり、かかる重合体は、粘着性が極めて低く、かかる重合体が繊維上に付着していても、花粉のような浮遊粒子は付着しにくく、落ちやすいという効果を奏するものである。
【0018】
本発明は、かかる制電性もしくは導電性を有する重合体が、繊維構造物を構成する布帛の少なくとも表面に固着した繊維構造物であって、かかる繊維構造物の20℃×30%RH環境下での摩擦帯電圧を4KV以下とするものであり、かかる機能を付与することにより、静電気によって引き寄せられる花粉の付着を防止することが可能となるものである。
【0019】
かかる摩擦帯電圧の測定は、JIS L1094B法(摩擦帯電圧測定法)に基づいて測定する。
【0020】
本発明は、さらに布帛表面にフルオロアルキル基を有する(メタ)アクリル酸エステルを必須の重合単位とする重合体が固着しているものであるが、かかる重合体は制電性もしくは導電性を有する重合体の上に固着していてもよく、また制電性もしくは導電性を有する重合体と混在していてもよい。かかるフルオロアルキル基を有する重合体は、他の重合性モノマとの共重合体であっても良い。
【0021】
かかるフルオロアルキル基を有する重合体が布帛表面に付着していることにより、水分を好む花粉を寄せ付けにくいという花粉付着防止性能をさらに向上させるものである。
【0022】
本発明でいうフルオロアルキル基を有する(メタ)アクリル酸エステルとは、フルオロアルキル基が(メタ)アクリル酸エステルのアルコール残基部分に存在する化合物をいう。
【0023】
フルオロアルキル基とは、アルキル基の水素原子の2個以上がフッ素原子に置換された基をいう。フルオロアルキル基の炭素数は2〜20が好ましく、特に6〜16が好ましい。また、フルオロアルキル基は、直鎖状または分岐状の基が好ましい。分岐状の基である場合には、分岐部分がフルオロアルキル基の末端部分に存在し、かつ、炭素数1〜4程度の短鎖であるのが好ましい。 さらにフルオロアルキル基は、アルキル基の水素原子の全てがフッ素原子に置換された基(すなわちパーフルオロアルキル基)、またはパーフルオロアルキル基を末端部分に有する基が好ましい。
【0024】
パーフルオロアルキル基の場合、炭素数は、1〜20が好ましく、4〜16が特に好ましい。炭素数が4未満の場合には、加工剤組成物の撥水性能が低下する傾向にあり、16より多い場合には、共重合体が常温で固体となり、昇華性も大きく、取扱いが困難になる恐れがある。
【0025】
本発明の重合体は、かかる重合単位を1種または2種以上含んでいてもよい。かかる重合単位を2種以上含む場合には、炭素数の異なるフルオロアルキル基を有する(メタ)アクリル酸エステルを用いることが好ましい。
【0026】
また、本発明の重合体は、ポリアルキレングリコール(メタ)アクリル酸エステルを重合単位として含むことが好ましい。かかるポリアルキレングリコールは、ポリエチレングリコールおよび/またはポリプロピレングリコールであることが好ましい。特に好ましくは疎水性のポリプロピレングリコールであり、これを含むことによりMMD、SMDの数値が低くなり、平滑性が向上し、花粉付着防止性がさらに大きく向上するものである。
【0027】
かかる重合体の付与方法としては、特に限定されるものではないが、フルオロアルキル基を有する(メタ)アクリル酸エステルを必須の重合単位とする重合体に、アミノプラスト樹脂および/または、多官能性イソシアネート基含有ウレタン樹脂などの架橋効果を有する樹脂を加えた処理液を布帛に付着した後、熱処理されることが好ましい。処理液を付与する方法は、かかる処理液に布帛を浸漬後パッディング法で付与する方法、またはスプレー法で付与することが好ましい。熱処理は、乾熱処理または湿熱処理のいずれかであり、好ましくは100〜200℃の乾熱処理が好ましい。100℃未満であると洗濯耐久性が不十分であり、200℃を越えると繊維の黄変、脆化が生じる傾向にある。
【0028】
かかる重合体は単繊維に均一に被膜として被覆されている必要はなく、繊維束をかかる重合体が覆っていればよい。このことからかかる重合体が布帛にコーティングされ、布帛の片面または両面にシート状に付着していても良い。
【0029】
本発明でいう摩擦係数の平均偏差は、KES法による布帛表面の摩擦係数の平均偏差(MMD)であり、タテ方向、ヨコ方向の各々の値が0.04以下であることが好ましい。本発明でいうタテ方向とは布帛の長さ方向であり、ヨコ方向とは布帛の幅方向である。MMDが大きいということは摩擦係数の変動が大きく布帛表面を摩擦した時、粘着性が高く引っかかりやすいことを意味する。MMDが0.04より大きいと摩擦時のひっかかりが大きくなり、花粉が布帛表面に引っかかって付着しやすく、落ちにくくなってしまうものである。
【0030】
本発明のMMDは、カトーテック(株)KES−FB4を用い20℃×65%RHの環境下で測定する。20gf/cmの張力をかけた布帛に、0.5mmΦのピアノ線を10本並べ5×5mmに面上に巻いた接触子を50gfの力で接触面を布帛に圧着させ、0.1cm/秒の一定の速度で水平に2cm移動させた時の摩擦係数の平均偏差である。
【0031】
本発明でいう表面粗さの平均偏差(SMD)は、KES法による布帛の表面粗さであり、タテ方向、ヨコ方向の各々の値が4.0μm以下であることが好ましい。SMDが大きいということは布帛表面の凹凸が大きいことを意味する。SMDが4.0μmより大きいと布帛表面の凹部に花粉は入り込み落ちにくくなってしまうものである。
【0032】
本発明のSMDは、カトーテック(株)KES−FB4を用い20℃×65%RHの環境下で測定する。20gf/cmの張力をかけた布帛に、0.5mmΦのピアノ線を5mm幅に1本折り曲げた接触子を10gfで試料に圧着する。この接触子はバネで圧着されるが、バネの定数は25gfとする。圧着させた摩擦子を0.1cm/秒の一定の速度で水平に2cm移動させた時の布帛表面粗さの平均偏差である。
【0033】
また、本発明は繊維構造物を構成する繊維として、制電性または導電性成分を含有する繊維が、構成繊維の少なくとも一部に存在していることがより好ましい効果を奏する。
【0034】
かかる制電性または導電性成分を含有する繊維としては、ポリアルキレングリコール系化合物やカーボンブラックの粒子を、繊維を紡糸する際に含有させたものが好ましく使用される。
【0035】
本発明においては、布帛を構成する繊維または繊維束が交錯してできる隙間が、30μm以下であることが好ましい。花粉の粒径は30μm前後であるため隙間が30μmを越えると、隙間から花粉が繊維構造物の内部に入り込む可能性があるためである。
【0036】
かかる繊維構造物を構成する布帛の繊維として、合成繊維、天然繊維、および再生繊維から選ばれた少なくとも1種を使用することができるが、かかる合成繊維としてはポリエステル系繊維またはポリアミド系繊維またはポリオレフィン系繊維等が好ましい。ポリエステル系繊維としては、ポリエチレンテレフタレート、ポリトリメチレンテレフタレート、ポリブチレンテレフタレートやこれらを主成分とした共重合ポリエステル系繊維等が含まれ、また、ポリアミド系繊維としては、ナイロン6,ナイロン66および第3成分を共重合したもの等である。ポリオレフィン系繊維としては、ポリプロピレン、ポリエチレン等が含まれる。また天然繊維としては、絹等が好ましく、再生繊維としてはビスコースレーヨン等が好ましい。
【0037】
本発明の繊維構造物は、花粉が付着しにくいということから、コート、ブルゾン、ウインドブレーカー、シャツ、スカート、スラックス、スカーフ、エプロン、帽子、手袋、腕カバーまたは布団カバー、布団干しカバーなどの用途に好適に使用されるものである。
【0038】
【実施例】
以下、実施例によって本発明をさらに詳細に説明するが、本発明はこれら実施例に限定されるものではない。なお、実施例中の品質評価は次の方法に従った。
【0039】

【0040】
かかるポリエチレン袋を1回/1秒の速度で縛り口を基準に上下に往復100回振ったのち、繊維布帛を取り出し、繊維布帛表面を50倍に拡大した写真を3カ所撮り、写真の7.5×10cmの範囲の擬似花粉の個数を数え、3カ所の平均を計算する。

BACKGROUND OF THE INVENTION
The present invention relates to a fiber structure characterized in that it is excellent in preventing pollen adhesion to which pollen that causes pollinosis is difficult to adhere, and that pollen hardly enters inside the structure.
[0002]
[Prior art]
Once hay fever occurs, the disease occurs almost every year from February to April when cedar pollen is scattered, and it is difficult to cure completely. In addition, hay fever is not only cedar pollen but also allergens such as Japanese cypress, rice, ragweed, alder and allergens, and the incidence of patients is increasing year by year, but the amount of pollen scattered tends to increase year by year. The treatment method has not been established. It is also a serious problem for farmers who handle flowers and gardening enthusiasts who touch flowers as a hobby.
[0003]
Conventionally, hay fever patients have taken measures to avoid touching pollen as much as possible. It is most effective to not go outside when pollen is scattered, but it is difficult, and as a possible measure, protect yourself with masks, glasses, goggles, hats, etc. I came. However, if you go indoors after going out, you will bring in pollen that is attached to clothing outdoors. Once pollen is brought indoors, it is difficult to take it out outdoors. Therefore, there is a demand for clothing that is difficult for pollen to adhere to and that prevents pollen from entering the fiber structure.
[0004]
As a method for preventing pollen, a pollen-supplementing fiber structure containing a compound having a sulfonate, carboxylate, phosphate, basic group or formyl group and having a parallel moisture content of 1% or more has been proposed. (See Patent Document 1). These chemically adsorb pollen allergens, and when they are used as clothing, they enter the house with pollen attached. In short, pollen is brought into the house, which is undesirable for people with hay fever.
[0005]
Moreover, as a thing which does not make pollen adhere, the pollen prevention cover for laundry formed with the perforated film / sheet is proposed (refer patent document 2). These are films that do not allow pollen to pass through, but use films that have pores in the size range that allows water vapor to pass through. However, because they are films, they are not fashionable when used as general clothing, and as interior goods such as curtains. However, it was lacking in versatility such as no drape. In addition, the film has a problem that static electricity is easily generated, pollen is easily attracted, and pollen once attached cannot be easily removed.
[0006]
As clothing, clothing that uses conductive fibers and is difficult to adhere pollen due to static electricity has been commercialized, but the gap between the warp yarn and the adjacent warp yarn, the gap between the weft yarn and the adjacent weft yarn is large, There is a possibility that pollen may get into clothes.

[Problems to be solved by the invention]
In view of the background of such prior art, the present invention is intended to provide an excellent fiber structure in which pollen is less likely to adhere and pollen is less likely to fall inside the fiber structure and moreover it is difficult to bring pollen indoors. It is.
[0010]
[Means for Solving the Problems]
The present invention employs the following means in order to solve such problems. That is, in the fiber structure of the present invention, a composition comprising an antistatic or conductive polymer is fixed to at least the surface of the fiber structure, and the surface of the fiber structure is the following surface It is characterized by satisfying all the characteristics.
[0011]
(A) The frictional voltage is 4 KV or less in an environment of 20 ° C. × 30% RH.
[0012]
(B) The vertical and horizontal values of the mean deviation (MMD) of the friction coefficient of the surface by the KES method are 0.04 or less.
[0013]
(C) The average deviation (SMD) of the surface roughness is 4.0 μm or less in each of the vertical and horizontal directions.
[0014]
DETAILED DESCRIPTION OF THE INVENTION
The present invention relates to the above-described problem, that is, a fiber structure having a structure in which pollen is difficult to adhere and is easy to fall, and pollen does not easily enter the fiber structure, and an outer garment or a futon drying cover that is required to be resistant to pollen. The necessary functions as an application in contact with such an external space are studied earnestly, and the adsorption of pollen to the fiber structure due to the generation of static electricity is suppressed, the adhesiveness of the fabric surface is low, and the fabric surface is smooth. Since it is a fiber structure and pollen easily adsorbs to moisture, paying attention to the fact that it has hydrophobicity that does not attract moisture, that is, having water repellency greatly improves pollen adhesion prevention, An antistatic or conductive polymer satisfying that the frictional voltage, the friction coefficient, and the surface roughness are within a specific range is fixed to the fiber structure. Was where, for the first time, one in which the investigation to solve such a problem in one fell swoop.
[0015]
In general, an antistatic agent having antistatic properties used for suppressing static electricity generated in a fiber fabric is that the antistatic agent itself absorbs moisture in the air and retains moisture when it is fixed to the fiber surface. Many of them improve the electrical conductivity and suppress the generation of static electricity. The antistatic agent having high humidity dependency, that is, the polymer having antistatic properties by absorbing moisture is fixed to the fiber surface as a solid when dried, but the polymer is absorbed by absorbing moisture. It liquefies and the polymer surface becomes sticky. Such a phenomenon is such that when floating particles such as floating pollen adhere due to physical impact or the like, such adhesiveness is difficult to seize and release pollen, and easily adheres to the fabric surface. As a result, when clothes made of such a fiber structure are worn, pollen is brought into the room.
[0016]
As the polymer having antistatic property or conductivity according to the present invention, a polymer which is not liquefied in an environment of 20 ° C. × 65% RH is preferably used.
[0017]
That is, such an antistatic or conductive polymer is coated on a polyester film, dried completely, and then left in an environment of 20 ° C. × 65% RH. Does not liquefy. That is, such a polymer has an extremely low adhesiveness, and even when such a polymer is adhered on the fiber, floating particles such as pollen are difficult to adhere and easily fall off.
[0018]
The present invention is a fiber structure in which such a polymer having antistatic or electrical conductivity is fixed to at least the surface of a fabric constituting the fiber structure, and the fiber structure is under a 20 ° C. × 30% RH environment. The frictional band voltage at 4 kV or less is provided, and by providing such a function, it is possible to prevent pollen from being attracted by static electricity.
[0019]
Such frictional voltage is measured based on JIS L1094B method (frictional voltage measurement method).
[0020]
In the present invention, a polymer having a (meth) acrylic acid ester having a fluoroalkyl group as an essential polymerization unit is fixed on the surface of the fabric. The polymer has antistatic or conductive properties. It may be fixed on the polymer, or may be mixed with a polymer having antistatic property or conductivity. Such a polymer having a fluoroalkyl group may be a copolymer with another polymerizable monomer.
[0021]
When the polymer having such a fluoroalkyl group adheres to the surface of the fabric, it further improves the pollen adhesion preventing performance such that it is difficult to attract pollen that prefers moisture.
[0022]
The (meth) acrylic acid ester having a fluoroalkyl group in the present invention refers to a compound in which the fluoroalkyl group is present in the alcohol residue portion of the (meth) acrylic acid ester.
[0023]
A fluoroalkyl group refers to a group in which two or more hydrogen atoms of an alkyl group are substituted with fluorine atoms. 2-20 are preferable and, as for carbon number of a fluoroalkyl group, 6-16 are especially preferable. The fluoroalkyl group is preferably a linear or branched group. In the case of a branched group, it is preferable that the branched portion is present at the terminal portion of the fluoroalkyl group and is a short chain having about 1 to 4 carbon atoms. Further, the fluoroalkyl group is preferably a group in which all of the hydrogen atoms of the alkyl group are substituted with fluorine atoms (that is, a perfluoroalkyl group) or a group having a perfluoroalkyl group at the terminal portion.
[0024]
In the case of a perfluoroalkyl group, the carbon number is preferably 1-20, and particularly preferably 4-16. When the number of carbon atoms is less than 4, the water repellency of the processing agent composition tends to decrease. When the number is more than 16, the copolymer becomes solid at room temperature, has high sublimation properties, and is difficult to handle. There is a fear.
[0025]
The polymer of the present invention may contain one or more such polymer units. When two or more kinds of such polymerized units are included, it is preferable to use (meth) acrylic acid esters having fluoroalkyl groups having different carbon numbers.
[0026]
Moreover, it is preferable that the polymer of this invention contains polyalkylene glycol (meth) acrylic acid ester as a polymer unit. Such polyalkylene glycol is preferably polyethylene glycol and / or polypropylene glycol. Hydrophobic polypropylene glycol is particularly preferred, and inclusion thereof lowers the numerical values of MMD and SMD, improves smoothness, and further improves pollen adhesion prevention.
[0027]
A method for imparting such a polymer is not particularly limited, but a polymer having a (meth) acrylic acid ester having a fluoroalkyl group as an essential polymer unit is added to an aminoplast resin and / or a multifunctional compound. It is preferable to heat-treat after attaching the treatment liquid to which a resin having a crosslinking effect such as an isocyanate group-containing urethane resin is added to the fabric. As a method for applying the treatment liquid, it is preferable to apply the treatment liquid by a padding method after dipping the fabric in the treatment liquid, or a spray method. The heat treatment is either a dry heat treatment or a wet heat treatment, preferably a dry heat treatment at 100 to 200 ° C. When the temperature is less than 100 ° C, the washing durability is insufficient, and when the temperature exceeds 200 ° C, the fiber tends to yellow or become brittle.
[0028]
Such a polymer does not need to be uniformly coated on a single fiber as a film, and it is sufficient that the polymer covers the fiber bundle. For this reason, such a polymer may be coated on the fabric, and may be adhered to one side or both sides of the fabric in the form of a sheet.
[0029]
The average deviation of the friction coefficient referred to in the present invention is the average deviation (MMD) of the friction coefficient of the fabric surface by the KES method, and it is preferable that each value in the vertical direction and the horizontal direction is 0.04 or less. In the present invention, the vertical direction is the length direction of the fabric, and the horizontal direction is the width direction of the fabric. When the MMD is large, the fluctuation of the friction coefficient is large, and when the fabric surface is rubbed, it means that the adhesiveness is high and it is easily caught. When the MMD is larger than 0.04, the catch at the time of friction increases, and the pollen is easily caught on the surface of the fabric and becomes difficult to fall off.
[0030]
The MMD of the present invention is measured under an environment of 20 ° C. × 65% RH using Kato Tech Co., Ltd. KES-FB4. The contact surface was crimped to the fabric with a force of 50 gf by placing 10 pieces of 0.5 mmΦ piano wires on a fabric applied with a tension of 20 gf / cm and wound on the surface to 5 × 5 mm, and 0.1 cm / sec. Is the average deviation of the coefficient of friction when moved horizontally by 2 cm at a constant speed.
[0031]
The average deviation (SMD) of the surface roughness referred to in the present invention is the surface roughness of the fabric by the KES method, and it is preferable that each value in the vertical direction and the horizontal direction is 4.0 μm or less. A large SMD means that the unevenness of the fabric surface is large. If the SMD is larger than 4.0 μm, pollen will not easily enter the recesses on the fabric surface.
[0032]
The SMD of the present invention is measured in an environment of 20 ° C. × 65% RH using Kato Tech Co., Ltd. KES-FB4. A contact obtained by bending a piano wire of 0.5 mmΦ to a width of 5 mm and crimping it to a fabric with a tension of 20 gf / cm is bonded to the sample at 10 gf. This contact is pressed by a spring, and the constant of the spring is 25 gf. It is an average deviation of the surface roughness of the fabric when the pressure-bonded friction element is moved 2 cm horizontally at a constant speed of 0.1 cm / second.
[0033]
Moreover, this invention has a more preferable effect that the fiber containing an antistatic or electroconductive component exists in at least one part of a constituent fiber as a fiber which comprises a fiber structure.
[0034]
As the fiber containing the antistatic or conductive component, a fiber containing a polyalkylene glycol compound or carbon black particles when the fiber is spun is preferably used.
[0035]
In the present invention, the gap formed by the fibers or fiber bundles composing the fabric is preferably 30 μm or less. This is because the pollen particle size is around 30 μm, and if the gap exceeds 30 μm, the pollen may enter the fiber structure from the gap.
[0036]
As the fiber of the fabric constituting the fiber structure, at least one selected from synthetic fiber, natural fiber, and recycled fiber can be used. As the synthetic fiber, polyester fiber, polyamide fiber, or polyolefin can be used. System fibers and the like are preferable. Examples of the polyester fiber include polyethylene terephthalate, polytrimethylene terephthalate, polybutylene terephthalate, and copolymer polyester fiber based on these, and examples of the polyamide fiber include nylon 6, nylon 66, and third fiber. And those obtained by copolymerizing components. Polyolefin fibers include polypropylene, polyethylene and the like. The natural fiber is preferably silk or the like, and the regenerated fiber is preferably viscose rayon or the like.
[0037]
Since the fiber structure of the present invention is hard to adhere pollen, it can be used for coats, blousons, windbreakers, shirts, skirts, slacks, scarves, aprons, hats, gloves, arm covers or duvet covers, and futon covers. It is used suitably for.
