近年、快適生活を目指した生活環境の多様化に伴い、消臭性などの各種機能を有する繊維やそれを用いた繊維構造体が提案されている。例えば、消臭性微粒子を含有する繊維形成性熱可塑性高分子化合物を溶融紡糸して得られた機能性繊維（例えば特許文献１参照）や、消臭性微粒子を後加工によりバインダー樹脂を介して繊維構造体に付与して得られた消臭性繊維構造体などが提案されている（例えば特許文献２参照）。
しかしながら、これらの消臭性繊維構造体において、消臭性の点でまだ十分とはいえなかった。
他方、近年では、ナノファイバーと称せられる超極細繊維を用いた繊維構造体が提案されている（例えば特許文献３参照）。
In recent years, with the diversification of living environments aimed at comfortable living, fibers having various functions such as deodorizing properties and fiber structures using the same have been proposed. For example, functional fibers obtained by melt spinning fiber-forming thermoplastic polymer compounds containing deodorant fine particles (see, for example, Patent Document 1) or deodorant fine particles via post-processing through a binder resin A deodorant fiber structure obtained by applying to a fiber structure has been proposed (see, for example, Patent Document 2).
However, these deodorant fiber structures have not been sufficient in terms of deodorization.

When a polyester copolymer obtained by copolymerizing polyethylene glycol and / or a derivative thereof is added to the fiber, a hydrophilic group is imparted to the fiber, so that it is easy to adsorb odor components, and as a result, particularly excellent deodorizing properties can be achieved. The present invention has been completed by repeated headings and further intensive studies.

以下、本発明の実施の形態について詳細に説明する。
まず、フィラメント糸Ａ（以下、「ナノファイバー」と称することもある。）において、その単繊維径（単繊維の直径）が１０００ｎｍ以下（好ましくは１０〜１０００ｎｍ、より好ましくは１００〜９００ｎｍ、特に好ましくは５５０〜９００ｎｍ）の範囲内であることが肝要である。かかる単繊維径を単繊維繊度に換算すると、０．０１ｄｔｅｘ以下に相当する。該単繊維径が１０００ｎｍよりも大きい場合は、本発明の主目的とする優れた消臭性が得られないおそれがあり好ましくない。ここで、単繊維の断面形状が丸断面以外の異型断面である場合には、外接円の直径を単繊維径とする。なお、単繊維径は、透過型電子顕微鏡で繊維の横断面を撮影することにより測定が可能である。また、単繊維繊度のばらつきが−２０％〜＋２０％の範囲内であることが好ましい。
Hereinafter, embodiments of the present invention will be described in detail.
First, in the filament yarn A (hereinafter sometimes referred to as “nanofiber”), the single fiber diameter (single fiber diameter) is 1000 nm or less (preferably 10 to 1000 nm, more preferably 100 to 900 nm, particularly preferably. Is in the range of 550 to 900 nm). When this single fiber diameter is converted into a single fiber fineness, it corresponds to 0.01 dtex or less. When the single fiber diameter is larger than 1000 nm, the excellent deodorizing property as the main object of the present invention may not be obtained, which is not preferable. Here, when the cross-sectional shape of the single fiber is an atypical cross section other than the round cross section, the diameter of the circumscribed circle is defined as the single fiber diameter. The single fiber diameter can be measured by photographing the cross section of the fiber with a transmission electron microscope. Moreover, it is preferable that the dispersion | variation in single fiber fineness exists in the range of -20%-+ 20%.
前記フィラメント糸Ａにおいて、フィラメント数は特に限定されないが、優れた消臭性を得る上で５００本以上（より好ましくは２０００〜１００００本）であることが好ましい。また、フィラメント糸Ａの総繊度（単繊維繊度とフィラメント数との積）としては、５〜１５０ｄｔｅｘの範囲内であることが好ましい。 In the filament yarn A, the number of filaments is not particularly limited, but is preferably 500 or more (more preferably 2000 to 10,000) in order to obtain excellent deodorizing properties. The total fineness of the filament yarn A (the product of the single fiber fineness and the number of filaments) is preferably in the range of 5 to 150 dtex.
前記フィラメント糸Ａの繊維形態は特に限定されないが、長繊維（マルチフィラメント糸）であることが好ましい。短繊維（紡績糸）の場合は、繊維が集束しているため、十分な消臭性が得られないおそれがある。単繊維の断面形状は特に限定されず、丸、三角、扁平、中空など公知の断面形状でよい。また、通常の空気加工、仮撚捲縮加工が施されていてもさしつかえない。 The fiber form of the filament yarn A is not particularly limited, but is preferably a long fiber (multifilament yarn). In the case of a short fiber (spun yarn), there is a possibility that sufficient deodorizing properties cannot be obtained because the fibers are concentrated. The cross-sectional shape of the single fiber is not particularly limited, and may be a known cross-sectional shape such as a circle, a triangle, a flat shape, or a hollow shape. In addition, normal air processing and false twist crimping may be applied.
前記フィラメント糸Ａを形成するポリマーの種類としては、ポリエステルにポリエチレングリコールおよび／またはその誘導体を共重合してなるポリエステル共重合体である。
ここで、ポリエステルにポリエチレングリコールおよび／またはその誘導体が共重合されていない場合は、本発明の主目的である優れた消臭性が得られないおそれがあり、好ましくない。
The type of polymer forming the filament yarn A is a polyester copolymer obtained by copolymerizing polyester with polyethylene glycol and / or a derivative thereof.
Here, when polyethylene glycol and / or a derivative thereof are not copolymerized with the polyester, the excellent deodorizing property which is the main object of the present invention may not be obtained, which is not preferable.
また、本発明におけるポリエステルとしては、テレフタル酸とエチレングリコールの重縮合反応により得られるエチレンテレフタレート単位を主たる繰り返し単位とするポリエステルが好ましく用いられる。ここで主たるとは全繰り返し単位中７０モル％以上がエチレンテレフタレート単位であることを表す。好ましくは８０モル％以上、より好ましくは９０モル％以上である。 Further, as the polyester in the present invention, a polyester having an ethylene terephthalate unit obtained by a polycondensation reaction of terephthalic acid and ethylene glycol as a main repeating unit is preferably used. Here, “main” means that 70 mol% or more of all repeating units are ethylene terephthalate units. Preferably it is 80 mol% or more, More preferably, it is 90 mol% or more.
本発明に使用するポリエステルの製造方法は、通常知られている製造方法が用いられる。すなわち、まずテレフタル酸の如きジカルボン酸成分とエチレングリコールの如きグリコール成分とを直接エステル化反応させる方法（エステル化反応工程）、又はテレフタル酸ジメチルの如きジカルボン酸成分の低級アルキルエステルとエチレングリコールの如きグリコール成分とをエステル交換反応触媒の存在下エステル交換反応させる方法（エステル交換反応工程）などにより、ジカルボン酸のグリコールエステル及び／又はその低重合体を製造する。次いでこの反応生成物を重合触媒の存在下で減圧加熱して所定の重合度になるまで重縮合反応させることによって（重縮合反応工程）、目的とするポリエステルが製造される。上述したエステル交換反応触媒としてはカルシウム化合物、マグネシウム化合物、マンガン化合物、亜鉛化合物又はチタン化合物等が好ましく例示され、重合触媒としてはアンチモン化合物、ゲルマニウム化合物、チタン化合物、アルミニウム化合物が好ましく例示される。 As a method for producing the polyester used in the present invention, a generally known production method is used. That is, first, a method in which a dicarboxylic acid component such as terephthalic acid is directly esterified with a glycol component such as ethylene glycol (esterification reaction step), or a lower alkyl ester of a dicarboxylic acid component such as dimethyl terephthalate and ethylene glycol is used. A glycol ester of a dicarboxylic acid and / or a low polymer thereof is produced by a method of transesterification with a glycol component in the presence of a transesterification catalyst (transesterification reaction step). Next, this reaction product is heated under reduced pressure in the presence of a polymerization catalyst and subjected to a polycondensation reaction until a predetermined degree of polymerization is obtained (polycondensation reaction step), whereby the desired polyester is produced. Preferred examples of the transesterification reaction catalyst include calcium compounds, magnesium compounds, manganese compounds, zinc compounds, and titanium compounds. Preferred examples of the polymerization catalyst include antimony compounds, germanium compounds, titanium compounds, and aluminum compounds.
また、ポリエステルに共重合されるポリエチレングリコールおよび／またはその誘導体としては、ポリエチレングリコールでもよいが、優れた消臭性を得る上で、下記一般式（１）で表されるポリエチレングリコール誘導体が好ましい。ポリエステルにかかるポリエチレングリコール誘導体が共重合されていると、繊維表面に親水基が付与され、臭気成分をより吸着しやすくなるため、優れた消臭性が得られる。特開２００６−１０４３７９号公報の化学式（ＩＩＩ）に記載されているような通常のポリエチレングリコールの場合、ポリエチレングリコールの主鎖に共重合されるため、下記一般式（１）で表されるポリエチレングリコール誘導体を共重合したポリエステルほどには消臭性が得られない可能性がある。 In addition, polyethylene glycol and / or a derivative thereof copolymerized with polyester may be polyethylene glycol, but a polyethylene glycol derivative represented by the following general formula (1) is preferable for obtaining excellent deodorizing properties. When the polyethylene glycol derivative relating to the polyester is copolymerized, a hydrophilic group is imparted to the fiber surface and the odor component is more easily adsorbed, so that excellent deodorizing properties can be obtained. In the case of ordinary polyethylene glycol as described in chemical formula (III) of JP-A-2006-104379, since it is copolymerized with the main chain of polyethylene glycol, polyethylene glycol represented by the following general formula (1) There is a possibility that the deodorizing property may not be obtained as much as the polyester copolymerized with the derivative.
また、ポリエチレングリコールおよび／またはその誘導体の共重合量としては全ポリエステル質量に対して１．０〜３０．０質量％（より好ましくは１．５〜２０質量％）の範囲内であることが好ましい。かかる共重合量が１．０質量％未満の場合、得られるポリエステル繊維の消臭性が不十分となり、３０．０質量％を超えると本来ポリエステルが有している耐熱性、寸法安定性等の特徴が損なわれるおそれがある。 The copolymerization amount of polyethylene glycol and / or a derivative thereof is preferably in the range of 1.0 to 30.0% by mass (more preferably 1.5 to 20% by mass) with respect to the total polyester mass. . If the copolymerization amount is less than 1.0% by mass, the resulting polyester fiber has insufficient deodorizing properties, and if it exceeds 30.0% by mass, the polyester inherently has heat resistance, dimensional stability, etc. Features may be impaired.
一般式（１）で表されるジオール成分の化合物の官能基Ｒは炭素数１〜１８個の炭化水素基を表す。より具体的には、メチル基、エチル基、ｎ−プロピル基、イソプロピル基、ｎ−ブチル基、イソブチル基、ｔ−ブチル基、ペンチル基、ヘキシル基、ヘプチル基、オクチル基、２−エチルヘキシル基、ｎ−ノニル基、分岐のあるノニル基、デシル基、ラウリル基等のドデシル基、ミリスチル基等のテトラデシル基、パルミチル基等のヘキサデシル基、ステアリル基等のオクタデシル基を挙げることができる。官能基Ｒが炭素数１８個を超えると、共重合されたポリエステルの熱分解が起こりやすくなるなどの問題が発生するおそれがある。またエチレンオキサイド単位の重合度を表しているｎは４０から１５０であることが好ましい。４０未満であるとポリエステルの制電性が発現しないことがあり、１５０を超えると実用に耐えうる高い固有粘度（重合度）のポリエステルを得ることが困難になるか、ポリエステルの耐熱性が極端に低下するおそれがある。より好ましいのは、官能基Ｒがメチル基又はオクタデシル基であり、ｎは４０〜１００の範囲の場合であり、より好ましくはｎは４０〜８０の場合である。ここでポリエステル製造時における上記式（１）の化合物の添加時期としては特に限定はないが、共重合率を高めるため、直接エステル化反応の開始前から反応後の任意の段階、あるいはエステル交換反応終了後、エステル交換反応開始前の段階が好ましい。 The functional group R of the diol component compound represented by the general formula (1) represents a hydrocarbon group having 1 to 18 carbon atoms. More specifically, methyl group, ethyl group, n-propyl group, isopropyl group, n-butyl group, isobutyl group, t-butyl group, pentyl group, hexyl group, heptyl group, octyl group, 2-ethylhexyl group, Examples thereof include an n-nonyl group, a branched nonyl group, a dodecyl group such as a decyl group and a lauryl group, a tetradecyl group such as a myristyl group, a hexadecyl group such as a palmityl group, and an octadecyl group such as a stearyl group. When the functional group R exceeds 18 carbon atoms, there is a possibility that problems such as thermal decomposition of the copolymerized polyester easily occur. Further, n representing the degree of polymerization of ethylene oxide units is preferably 40 to 150. If it is less than 40, the antistatic property of the polyester may not be exhibited. If it exceeds 150, it is difficult to obtain a polyester having a high intrinsic viscosity (degree of polymerization) that can withstand practical use, or the heat resistance of the polyester is extremely high. May decrease. More preferably, the functional group R is a methyl group or an octadecyl group, and n is in the range of 40-100, more preferably n is 40-80. Here, the addition time of the compound of the above formula (1) during the production of the polyester is not particularly limited, but in order to increase the copolymerization rate, any stage after the reaction from the start of the direct esterification reaction or the transesterification reaction After completion, the stage before the start of the transesterification reaction is preferred.
前記のポリエステル共重合体は、制電性を付加するためスルホイソフタル酸塩をポリエステテルを構成するジカルボン酸に対して、０．２〜１．０モル％共重合していてもよい。スルホイソフタル酸塩としては、スルホイソフタル酸金属塩、スルホイソフタル酸（４級）アンモニウム塩、スルホイソフタル酸ホスホニウム塩を挙げることができる。その中でスルホイソフタル酸金属塩を形成する金属種類としては、Ｌｉ、Ｎａ、Ｋ、Ｃａ、Ｍｇ、Ａｌなどが挙げられるが、制電性、コスト面を考慮するとアルカリ金属種が好ましく、中でもＮａ塩がより好ましい。すなわちスルホイソフタル酸塩としてはスルホイソフタル酸アルカリ金属塩が好ましく、具体的にはスルホイソフタル酸ナトリム塩、スルホイソフタル酸リチウム塩、スルホイソフタル酸カリウム塩が挙げられる。これらは単独で用いても２種以上を併用してもよい。 In order to add antistatic properties, the polyester copolymer may be copolymerized with sulfoisophthalate in an amount of 0.2 to 1.0 mol% with respect to the dicarboxylic acid constituting the polyester. Examples of sulfoisophthalic acid salts include sulfoisophthalic acid metal salts, sulfoisophthalic acid (quaternary) ammonium salts, and sulfoisophthalic acid phosphonium salts. Among them, the metal types forming the metal salt of sulfoisophthalic acid include Li, Na, K, Ca, Mg, Al, etc., but in view of antistatic properties and cost, alkali metal species are preferable. A salt is more preferred. That is, the sulfoisophthalic acid salt is preferably a sulfoisophthalic acid alkali metal salt, specifically, sulfoisophthalic acid sodium salt, sulfoisophthalic acid lithium salt, or sulfoisophthalic acid potassium salt. These may be used alone or in combination of two or more.
前記ポリエステル共重合体の固有粘度（溶媒：オルトクロロフェノール、測定温度：３５℃）は特に限定はないが、０．５〜１．０ｄＬ／ｇの範囲にあることが好ましい。該固有粘度が０．５ｄＬ／ｇ未満の場合、得られるポリエステル繊維の機械的特性が不十分となり、１．０ｄＬ／ｇを超える場合、溶融成形性が低下する為好ましくない、ポリエステルの固有粘度は０．６〜０．８ｄＬ／ｇの範囲が更に好ましい。 The intrinsic viscosity (solvent: orthochlorophenol, measurement temperature: 35 ° C.) of the polyester copolymer is not particularly limited, but is preferably in the range of 0.5 to 1.0 dL / g. When the intrinsic viscosity is less than 0.5 dL / g, the mechanical properties of the resulting polyester fiber are insufficient, and when it exceeds 1.0 dL / g, the melt moldability is lowered, which is not preferable. A range of 0.6 to 0.8 dL / g is more preferable.
前記ポリエステル共重合体には、必要に応じて少量の添加剤、例えば滑剤、ラジカル捕捉剤、酸化防止剤、固相重合促進剤、整色剤、蛍光増白剤、抗菌剤、紫外線吸収剤、光安添加するポリオキシエチレン構造の耐熱性を高める為、特に好ましく添加される。なかでも、優れた消臭性を得る上で、前記ポリエステル共重合体に光触媒微粒子が含まれることが好ましい。その際、かかる光触媒微粒子としては、光触媒酸化チタンが好適に例示される。該光触媒酸化チタンはアナターゼ型、ルチル型、アモルファス型のいずれでもよく、特に光触媒活性の強さからアナターゼ型酸化チタンが好適である。
前記光触媒微粒子の平均２次粒子径としては、０．８〜１．２μｍの範囲内であることが好ましい。
The polyester copolymer may contain a small amount of additives as necessary, for example, a lubricant, a radical scavenger, an antioxidant, a solid phase polymerization accelerator, a color adjuster, a fluorescent whitening agent, an antibacterial agent, an ultraviolet absorber, In order to increase the heat resistance of the polyoxyethylene structure to be added with light-anchored, it is particularly preferably added. Especially, when obtaining the outstanding deodorizing property, it is preferable that the photocatalyst fine particle is contained in the said polyester copolymer. In this case, photocatalytic titanium oxide is preferably exemplified as such photocatalytic fine particles. The photocatalytic titanium oxide may be any one of anatase type, rutile type, and amorphous type, and anatase type titanium oxide is particularly preferred because of its high photocatalytic activity.
The average secondary particle diameter of the photocatalyst fine particles is preferably in the range of 0.8 to 1.2 μm.
また、本発明の繊維構造体において、フィラメント糸Ａ同士が凝集密着することなく、ばらけた状態で存在することが好ましい。ここで、本発明でいう「ばらけた状態」とは、特開２００７−２９１５６７号公報の図１および図２に示すように、フィラメント糸Ａが互いに独立していることをいう。フィラメント糸Ａがこのようにばらけた状態で存在することにより、繊維構造体は、消臭性能を十分に発現できる。これに対して、特開２００７−２９１５６７号公報の図３および図４に示された、ナノファイバー同士が凝集密着した繊維構造体の場合、消臭性能を十分に発現できないおそれがある。なお、本発明において、「ばらけた状態」とは１００本以上のナノファイバーが密着凝集した単糸塊がないという意味であり、ナノファイバー同士は完全に独立している必要はなく、１００本未満のナノファイバーが凝集密着した単糸塊が存在してもよい。また、このような「ばらけた状態」とするには後記のように高圧水で処理するとよい。 Moreover, in the fiber structure of the present invention, it is preferable that the filament yarns A are present in a separated state without agglomeration and adhesion. Here, the “separated state” in the present invention means that the filament yarns A are independent from each other as shown in FIGS. 1 and 2 of JP-A-2007-291567. When the filament yarn A exists in such a dispersed state, the fiber structure can sufficiently exhibit the deodorizing performance. On the other hand, in the case of a fiber structure in which nanofibers are aggregated and adhered as shown in FIGS. 3 and 4 of Japanese Patent Application Laid-Open No. 2007-291567, there is a possibility that the deodorizing performance cannot be sufficiently exhibited. In the present invention, the “disjoint state” means that there is no single yarn lump in which 100 or more nanofibers are closely aggregated and aggregated, and the nanofibers do not need to be completely independent, but less than 100. There may be a single yarn mass in which the nanofibers are agglomerated and adhered. Further, in order to obtain such a “split state”, it is preferable to treat with high pressure water as described later.
本発明の繊維構造体において、前記のフィラメント糸Ａが３０重量%以上（より好ましくは５０重量％以上、さらに好ましくは７０重量%以上、特に好ましくは１００重量％）含まれることが好ましい。フィラメント糸Ａの含有量が３０重量％未満では、十分な消臭性が発現されないおそれがある。 In the fiber structure of the present invention, the filament yarn A is preferably contained in an amount of 30% by weight or more (more preferably 50% by weight or more, further preferably 70% by weight or more, particularly preferably 100% by weight). When the content of the filament yarn A is less than 30% by weight, there is a possibility that sufficient deodorizing properties may not be expressed.
本発明の繊維構造体において、繊維構造体の形態としては特に限定されず、織編物、フェルト、糸条、不織布などが例示される。なかでも織編物が好適である。
編物の場合では、Ｄ１／２×Ｃｏ×Ｗｅが１００００以上（より好ましくは２００００〜１０００００）であると、優れた消臭性が得られやすく好ましい。ただし、Ｄは前記マルチフィラメント糸条の総繊度（ｄｔｅｘ）、Ｃｏは２．５４ｃｍあたりのコース数、Ｗｅは２．５４ｃｍあたりのウエール数である。
In the fiber structure of the present invention, the form of the fiber structure is not particularly limited, and examples thereof include woven and knitted fabric, felt, yarn, and nonwoven fabric. Of these, woven or knitted fabric is preferred.
In the case of a knitted fabric, it is preferable that D 1/2 × Co × We is 10,000 or more (more preferably 20000 to 100,000) because excellent deodorizing properties are easily obtained. However, D is the total fineness (dtex) of the multifilament yarn, Co is the number of courses per 2.54 cm, and We is the number of wales per 2.54 cm.
一方、織物の場合では、下記式により算出されるカバーファクターＣＦが１５００以上（より好ましくは１７００〜３８００）であると、優れた消臭性が得られやすく好ましい。
ＣＦ＝（ＤＷｐ／１．１）１／２×ＭＷｐ＋（ＤＷｆ／１．１）１／２×ＭＷｆ
ただし、ＤＷｐは経糸総繊度（ｄｔｅｘ）、ＭＷｐは経糸織密度（本／２．５４ｃｍ）、ＤＷｆは緯糸総繊度（ｄｔｅｘ）、ＭＷｆは緯糸織密度（本／２．５４ｃｍ）である。
On the other hand, in the case of a woven fabric, it is preferable that the cover factor CF calculated by the following formula is 1500 or more (more preferably 1700 to 3800) because excellent deodorizing properties are easily obtained.
CF = (DWp / 1.1) 1/2 × MWp + (DWf / 1.1) 1/2 × MWf
However, DWp is the total warp fineness (dtex), MWp is the warp weave density (main / 2.54 cm), DWf is the total weft fineness (dtex), and MWf is the weft weave density (main / 2.54 cm).
なお、繊維構造体が織編物である場合、ナノファイバーはマルチフィラメント糸条として織編物中に配される。その際、マルチフィラメント糸条のナノファイバー数は、５００以上（より好ましくは２０００〜１００００）であることが好ましい。 When the fiber structure is a woven or knitted fabric, the nanofibers are arranged in the woven or knitted fabric as multifilament yarns. At that time, the number of nanofibers of the multifilament yarn is preferably 500 or more (more preferably 2000 to 10000).
また、繊維構造体が織物または編物である場合は、目付けは２０ｇ／ｍ２以上（好ましくは２０〜２００ｇ／ｍ２）であることが好ましい。該目付けが２０ｇ／ｍ２未満では、満足な消臭性が得られないおそれがある。
なお、本発明の繊維構造体において、フィラメント糸Ａ以外の他糸条が含まれる場合、かかる他糸条の繊維種類は限定されないが、リサクル性の点でポリエステル繊維糸条が好ましい。
Further, when the fiber structure is a woven fabric or a knitted fabric, the basis weight is preferably 20 g / m 2 or more (preferably 20 to 200 g / m 2 ). If the basis weight is less than 20 g / m 2 , satisfactory deodorizing properties may not be obtained.
In the fiber structure of the present invention, when other yarns other than the filament yarn A are included, the fiber type of the other yarns is not limited, but polyester fiber yarns are preferable from the viewpoint of recyclability.
本発明の繊維構造体は、例えば以下の製造方法により製造することができる。すなわち、海成分と島成分とからなり、かつ島成分の径が１０００ｎｍ以下の海島型複合繊維を用いて繊維構造体を得た後、前記の海成分を溶解除去し、必要に応じて高圧水で該繊維構造体を噴射処理することが好ましい。 The fiber structure of the present invention can be produced, for example, by the following production method. That is, after obtaining a fiber structure using a sea-island composite fiber composed of a sea component and an island component and having an island component diameter of 1000 nm or less, the sea component is dissolved and removed, and high-pressure water is used as necessary. It is preferable to spray the fiber structure.
ここで、海成分を溶解除去した直後、島成分（ナノファイバー）同士は凝集密着しているが、前記の噴射処理により、凝集密着した複数のナノファイバーがばらけた状態で存在することになる。その際、高圧水の圧力としては、３〜１０ＭＰａ（３０〜１００ｋｇｆ／ｃｍ２）の範囲が好ましく、装置としては、スパンレース用ウオーターニードル装置（噴射孔径は０．２ｍｍ以下が好ましい。）や超音波水が好適である。 Here, immediately after the sea component is dissolved and removed, the island components (nanofibers) are coherently adhered to each other, but a plurality of coherently adhered nanofibers are present in a dispersed state by the above-described injection treatment. At that time, as the pressure of the high pressure water, preferably in the range of 3~10MPa (30~100kgf / cm 2), as the device, water needle apparatus for spun lace (injection hole diameter is preferably not more than 0.2 mm.) And ultra Sonic water is preferred.
また、海島型複合繊維としては、以下のものが好適である。すなわち、ポリマーの組合せは、海成分ポリマーが島成分ポリマーよりも溶解性が高い組合せであれば任意であるが、特に溶解速度比（海／島）が２００以上であることが好ましい。かかる溶解速度比が２００未満の場合には、繊維断面中央部の海成分を溶解させている間に繊維断面表層部の島成分の一部も溶解されるため、海成分を完全に溶解除去するためには、島成分の何割かも減量されてしまうことになり、島成分の太さ斑や溶剤浸食による強度劣化が発生して、毛羽やピリングなどの品位に問題が生じやすくなる。 Further, as the sea-island type composite fibers, the following are suitable. That is, the combination of the polymers is arbitrary as long as the sea component polymer is a combination having higher solubility than the island component polymer, but the dissolution rate ratio (sea / island) is preferably 200 or more. When the dissolution rate ratio is less than 200, part of the island component of the fiber cross-section surface layer portion is dissolved while the sea component of the fiber cross-section central portion is dissolved, so the sea component is completely dissolved and removed. For this reason, the island component is reduced by a percentage, and strength deterioration due to the thickness variation of the island component and solvent erosion occurs, and problems such as fluff and pilling are likely to occur.
海成分ポリマーは、好ましくは島成分との溶解速度比が２００以上であればいかなるポリマーであってもよいが、特に繊維形成性の良好なポリエステル、ポリアミド、ポリスチレン、ポリエチレンなどが好ましい。例えば、アルカリ水溶液易溶解性ポリマーとしては、ポリ乳酸、超高分子量ポリアルキレンオキサイド縮合系ポリマー、ポリエチレングルコール系化合物共重合ポリエステル、ポリエチレングリコール系化合物と５−ナトリウムスルホン酸イソフタル酸の共重合ポリエステルが好適である。また、ナイロン６は、ギ酸溶解性があり、ポリスチレン・ポリエチレンはトルエンなど有機溶剤に非常によく溶ける。なかでも、アルカリ易溶解性と海島断面形成性とを両立させるため、ポリエステル系のポリマーとしては、５−ナトリウムスルホイソフタル酸６〜１２モル％と分子量４０００〜１２０００のポリエチレングルコールを３〜１０重量％共重合させた固有粘度が０．４〜０．６のポリエチレンテレフタレート系共重合ポリエステルが好ましい。ここで、５−ナトリウムイソフタル酸は親水性と溶融粘度向上に寄与し、ポリエチレングリコール（ＰＥＧ）は親水性を向上させる。なお、ＰＥＧは分子量が大きいほど、その高次構造に起因すると考えられる親水性増加効果が大きくなるが、反応性が悪くなってブレンド系になるため、耐熱性・紡糸安定性などの点から好ましくなくなる。また、共重合量が１０重量％以上になると、本来溶融粘度低下作用があるので、あまり好ましくなく、上記の範囲で、両成分を共重合することが好ましい。 The sea component polymer may be any polymer as long as the dissolution rate ratio with respect to the island component is 200 or more, but polyesters, polyamides, polystyrenes, polyethylenes, and the like having good fiber forming properties are particularly preferable. For example, as an easily soluble polymer in an alkaline aqueous solution, polylactic acid, an ultra-high molecular weight polyalkylene oxide condensation polymer, a polyethylene glycol compound copolymer polyester, a copolymer polyester of polyethylene glycol compound and 5-sodium sulfonic acid isophthalic acid may be used. Is preferred. Nylon 6 is soluble in formic acid, and polystyrene and polyethylene are very well soluble in organic solvents such as toluene. Among them, in order to achieve both easy alkali solubility and sea-island cross-section formability, the polyester-based polymer is 3 to 10% by weight of polyethylene glycol having 6 to 12 mol% of 5-sodium sulfoisophthalic acid and a molecular weight of 4000 to 12000. % Copolymerized polyethylene terephthalate copolymer polyester having an intrinsic viscosity of 0.4 to 0.6 is preferred. Here, 5-sodium isophthalic acid contributes to improving hydrophilicity and melt viscosity, and polyethylene glycol (PEG) improves hydrophilicity. PEG has a higher hydrophilicity effect, which is thought to be due to its higher order structure, as the molecular weight increases, but it is preferable from the viewpoints of heat resistance and spinning stability because the reactivity becomes poor and a blend system is formed. Disappear. In addition, when the copolymerization amount is 10% by weight or more, it is not preferable because it originally has an effect of decreasing the melt viscosity, and it is preferable to copolymerize both components within the above range.
一方、島成分ポリマーは、前記のポリエステル共重合体を用いる。上記の海成分ポリマーと島成分ポリマーからなる海島型複合繊維は、溶融紡糸時における海成分の溶融粘度が島成分ポリマーの溶融粘度よりも大きいことが好ましい。かかる関係にある場合には、海成分の複合重量比率が４０％未満と少なくなっても、島同士が接合したり、島成分の大部分が接合して海島型複合繊維とは異なるものになり難い。 On the other hand, the above-mentioned polyester copolymer is used as the island component polymer. The sea-island composite fiber composed of the sea component polymer and the island component polymer preferably has a sea component melt viscosity higher than that of the island component polymer during melt spinning. In such a relationship, even if the composite weight ratio of the sea component is less than 40%, the islands are joined together, or the majority of the island components are joined to be different from the sea-island type composite fiber. hard.
好ましい溶融粘度比（海／島）は、１．１〜２．０、特に１．３〜１．５の範囲である。この比が１．１倍未満の場合には溶融紡糸時に島成分が接合しやすくなり、一方２．０倍を越える場合には、粘度差が大きすぎるために紡糸調子が低下しやすい。 A preferred melt viscosity ratio (sea / island) is in the range of 1.1 to 2.0, especially 1.3 to 1.5. If this ratio is less than 1.1 times, the island components are likely to be joined during melt spinning, whereas if it exceeds 2.0 times, the viscosity difference is too large and the spinning tone tends to be lowered.
次に島数は、多いほど海成分を溶解除去して極細繊維を製造する場合の生産性が高くなり、しかも得られるナノファイバーの細さも顕著となってナノファイバー特有の柔らかさ、滑らかさを表現することができる点で１００以上（より好ましくは３００〜１０００）であることが好ましい。ここで、島数が１００未満の場合には、海成分を溶解除去しても極細繊度の単糸からなるハイマルチフィラメント糸を得ることができず本発明の目的を達成することができないおそれがある。なお、島数があまりに多くなりすぎると紡糸口金の製造コストが高くなるだけでなく、加工精度自体も低下しやすくなるので１００００以下とするのが好ましい。 Next, the greater the number of islands, the higher the productivity when producing ultrafine fibers by dissolving and removing sea components, and the fineness of the resulting nanofibers becomes remarkable, and the softness and smoothness that is unique to nanofibers. It is preferable that it is 100 or more (more preferably 300 to 1000) in that it can be expressed. Here, when the number of islands is less than 100, there is a possibility that even if the sea component is dissolved and removed, a high multifilament yarn composed of a single yarn having a very fineness cannot be obtained and the object of the present invention cannot be achieved. is there. If the number of islands is too large, not only the manufacturing cost of the spinneret increases, but also the processing accuracy itself tends to decrease.
次に、島成分の径は、１０００ｎｍ以下（好ましくは１０〜１０００ｎｍ）とする必要がある。また、海島複合繊維断面内の各島は、その径が均一であるほど海成分を除去して得られる編地の品位や耐久性が向上するので好ましい。 Next, the diameter of the island component needs to be 1000 nm or less (preferably 10 to 1000 nm). In addition, each island in the cross section of the sea-island composite fiber is preferably as the diameter is uniform because the quality and durability of the knitted fabric obtained by removing the sea component is improved.
前記の海島型複合繊維において、その海島複合重量比率（海：島）は、４０：６０〜５：９５の範囲が好ましく、特に３０：７０〜１０：９０の範囲が好ましい。かかる範囲であれば、島間の海成分の厚みを薄くすることができ、海成分の溶解除去が容易となり、島成分の極細繊維への転換が容易になるので好ましい。ここで海成分の割合が４０％を越える場合には海成分の厚みが厚くなりすぎ、一方５％未満の場合には海成分の量が少なくなりすぎて、島間に接合が発生しやすくなる。 In the sea-island composite fiber, the sea-island composite weight ratio (sea: island) is preferably in the range of 40:60 to 5:95, and particularly preferably in the range of 30:70 to 10:90. Within such a range, the thickness of the sea component between the islands can be reduced, the sea component can be easily dissolved and removed, and the conversion of the island component into ultrafine fibers is facilitated. Here, when the proportion of the sea component exceeds 40%, the thickness of the sea component becomes too thick. On the other hand, when the proportion is less than 5%, the amount of the sea component becomes too small, and joining between the islands easily occurs.
前記の海島型複合繊維において、その島間の海成分厚みが５００ｎｍ以下、特に２０〜２００ｎｍの範囲が適当であり、該厚みが５００ｎｍを越える場合には、該厚い海成分を溶解除去する間に島成分の溶解が進むため、島成分間の均質性が低下するだけでなく、毛羽やピリングなど着用時の欠陥や染め斑も発生しやすくなる。 In the above-mentioned sea-island type composite fiber, the thickness of the sea component between the islands is suitably 500 nm or less, particularly in the range of 20 to 200 nm. When the thickness exceeds 500 nm, the thick sea component is dissolved and removed. As the dissolution of the components progresses, not only the homogeneity between the island components decreases, but defects and dyeing spots such as fuzz and pilling are likely to occur.
前記の海島型複合繊維は、例えば以下の方法により容易に製造することができる。すなわち、まず溶融粘度が高く且つ易溶解性であるポリマーと溶融粘度が低く且つ難溶解性のポリマーとを、前者が海成分で後者が島成分となるように溶融紡糸する。ここで、海成分と島成分の溶融粘度の関係は重要で、海成分の比率が小さくなって島間の厚みが小さくなると、海成分の溶融粘度が小さい場合には島間の一部の流路を海成分が高速流動するようになり、島間に接合が起こりやすくなるので好ましくない。 The sea-island type composite fiber can be easily produced, for example, by the following method. That is, first, a polymer having a high melt viscosity and an easily soluble polymer and a polymer having a low melt viscosity and a hardly soluble polymer are melt-spun so that the former is a sea component and the latter is an island component. Here, the relationship between the melt viscosity of the sea component and the island component is important. When the sea component ratio decreases and the thickness between the islands decreases, when the melt viscosity of the sea component is small, some flow paths between the islands This is not preferable because sea components flow at high speed and joining between islands easily occurs.
溶融紡糸に用いられる紡糸口金としては、島成分を形成するための中空ピン群や微細孔群を有するものなど任意のものを用いることができる。例えば中空ピンや微細孔より押し出された島成分とその間を埋める形で流路を設計されている海成分流とを合流し、これを圧縮することにより海島断面形成がなされるいかなる紡糸口金でもよい。 As the spinneret used for melt spinning, any one such as a hollow pin group for forming an island component or a group having a fine hole group can be used. For example, any spinneret that forms a cross section of the sea island by joining the island component extruded from the hollow pin or the fine hole and the sea component flow designed to fill the gap between the sea component flow may be used. .
吐出された海島型断面複合繊維は、冷却風によって固化され、好ましくは４００〜６０００ｍ／分で溶融紡糸された後に巻き取られる。得られた未延伸糸は、別途延伸工程をとおして所望の強度・伸度・熱収縮特性を有する複合繊維とするか、あるいは、一旦巻き取ることなく一定速度でローラーに引き取り、引き続いて延伸工程をとおした後に巻き取る方法のいずれでも構わない。 The discharged sea-island type cross-section composite fiber is solidified by cooling air, and is preferably wound after being melt-spun at 400 to 6000 m / min. The obtained undrawn yarn is made into a composite fiber having desired strength, elongation, and heat shrinkage properties through a separate drawing process, or is taken up by a roller at a constant speed without being wound once, and subsequently drawn. Any of the methods of winding after passing through may be used.
ここで、特に微細な島径を有する海島型複合繊維を高効率で製造するために、通常のいわゆる配向結晶化を伴うネック延伸（配向結晶化延伸）に先立って、繊維構造は変化させないで繊維径のみを極細化する流動延伸工程を採用することが好ましい。流動延伸を容易とするため、熱容量の大きい水媒体を用いて繊維を均一に予熱し、低速で延伸することが好ましい。このようにすることにより延伸時に流動状態を形成しやすくなり、繊維の微細構造の発達を伴わずに容易に延伸することができる。このプロセスでは、特に海成分および島成分が共にガラス転移温度１００℃以下のポリマーであることが好ましい。具体的には６０〜１００℃、好ましくは６０〜８０℃の範囲の温水バスに浸漬して均一加熱を施し、延伸倍率は１０〜３０倍、供給速度は１〜１０ｍ／分、巻取り速度は３００ｍ／分以下、特に１０〜３００ｍ／分の範囲で実施することが好ましい。予熱温度不足および延伸速度が速すぎる場合には、目的とする高倍率延伸を達成することができなくなる。 Here, in order to produce a sea-island type composite fiber having a particularly fine island diameter with high efficiency, the fiber structure is not changed prior to neck stretching (orientation crystallization stretching) with ordinary so-called orientation crystallization. It is preferable to employ a fluid stretching process in which only the diameter is extremely reduced. In order to facilitate fluid drawing, it is preferable to preheat the fiber uniformly using an aqueous medium having a large heat capacity and draw at a low speed. By doing so, it becomes easy to form a fluid state at the time of stretching, and it can be easily stretched without development of the fine structure of the fiber. In this process, both the sea component and the island component are preferably polymers having a glass transition temperature of 100 ° C. or less. Specifically, it is immersed in a hot water bath in the range of 60 to 100 ° C., preferably 60 to 80 ° C., and uniformly heated, the draw ratio is 10 to 30 times, the supply speed is 1 to 10 m / min, and the winding speed is It is preferable to carry out in the range of 300 m / min or less, particularly 10 to 300 m / min. If the preheating temperature is insufficient and the stretching speed is too high, the desired high-magnification stretching cannot be achieved.
得られた流動状態で延伸された延伸糸は、その強伸度などの機械的特性を向上させるため、定法にしたがって６０〜２２０℃の温度で配向結晶化延伸する。該延伸条件がこの範囲外の温度では、得られる繊維の物性が不十分なものとなる。なお、この延伸倍率は、溶融紡糸条件、流動延伸条件、配向結晶化延伸条件などによって変わってくるが、該配向結晶化延伸条件で延伸可能な最大延伸倍率の０．６〜０．９５倍で延伸すればよい。 The drawn yarn drawn in the fluidized state is oriented, crystallized and drawn at a temperature of 60 to 220 ° C. in accordance with a conventional method in order to improve mechanical properties such as the strength and elongation. If the drawing conditions are outside this range, the properties of the resulting fiber will be insufficient. The draw ratio varies depending on the melt spinning conditions, flow stretching conditions, orientation crystallization stretching conditions, etc., but is 0.6 to 0.95 times the maximum draw ratio that can be stretched under the orientation crystallization stretching conditions. What is necessary is just to extend | stretch.
以上に説明した海島型複合繊維を、無撚あるいは必要に応じて追撚した上で、必要に応じて他糸条とともに織編物などの繊維構造体を得た後、前記の海成分をアルカリ水溶液で溶解除去し、前記のように高圧水で該繊維構造体を噴射処理することにより、ナノファイバー同士をばらけた状態にすることができる。 After the sea-island type composite fiber described above is untwisted or twisted as necessary, a fiber structure such as a woven or knitted fabric is obtained together with other yarns as necessary, and then the sea component is mixed with an alkaline aqueous solution. And the nanofibers can be separated from each other by spraying the fiber structure with high-pressure water as described above.
なお、前記のアルカリ水溶液による海成分の溶解除去処理の前および／または後に染色加工を施してもよい。さらに、常法の親水加工、起毛加工、紫外線遮蔽あるいは制電剤、さらには、抗菌剤、消臭剤、防虫剤、蓄光剤、再帰反射剤、マイナスイオン発生剤等の機能を付与する各種加工を付加適用してもよい。 In addition, you may give a dyeing process before and / or after the melt | dissolution removal process of the sea component by the said alkaline aqueous solution. In addition, conventional processing such as hydrophilic processing, brushed processing, ultraviolet shielding or antistatic agent, and various processing that provides functions such as antibacterial agent, deodorant agent, insect repellent agent, phosphorescent agent, retroreflective agent, negative ion generator, etc. May be additionally applied.
かくして得られた繊維構造体において、フィラメント糸Ａはその単繊維径が１０００ｎｍ以下と極めて小さいので、繊維の表面積が大きくなる。また同時に、フィラメント糸Ａが前記ポリエステル共重合体で形成されているので、繊維に親水基が付与されるため臭気成分を吸着しやすくなり、優れた消臭性が得られる。特に、フィラメント糸Ａに光触媒微粒子が含まれる場合、繊維に付与された親水基と光触媒微粒子との相乗効果により優れた消臭性が得られる。また、フィラメント糸Ａ同士が凝集密着することなく、ばらけた状態で存在していると特に優れた消臭性能を呈する。 In the fiber structure thus obtained, the filament yarn A has an extremely small single fiber diameter of 1000 nm or less, so that the surface area of the fiber increases. At the same time, since the filament yarn A is formed of the polyester copolymer, a hydrophilic group is imparted to the fiber, so that an odorous component is easily adsorbed and excellent deodorizing properties can be obtained. In particular, when the photocatalyst fine particles are contained in the filament yarn A, an excellent deodorizing property is obtained due to the synergistic effect of the hydrophilic group imparted to the fiber and the photocatalyst fine particles. In addition, when the filament yarns A are present in a separated state without agglomeration and close contact, particularly excellent deodorizing performance is exhibited.
