And a textile product is obtained.
以下、本発明の実施の形態について詳細に説明する。
まず、本発明で用いるポリエステルマルチフィラメント糸Ａはその単繊維径（単繊維の直径）が１０〜１０００ｎｍ（好ましくは１００〜８００ｎｍ、特に好ましくは５５０〜８００ｎｍ）であることが肝要である。かかる単繊維径を単糸繊度に換算すると、０．０００００１〜０．０１ｄｔｅｘに相当する。該単繊維径が１０００ｎｍを超える場合には、染色織物が超極細繊維特有のソフトな風合いを呈さず好ましくない。逆に、該単繊維径が１０ｎｍ未満の場合には繊維強度が低くなるため実用上好ましくない。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。
Hereinafter, embodiments of the present invention will be described in detail.
First, it is important that the polyester multifilament yarn A used in the present invention has a single fiber diameter (a single fiber diameter) of 10 to 1000 nm (preferably 100 to 800 nm, particularly preferably 550 to 800 nm). When this single fiber diameter is converted into a single yarn fineness, it corresponds to 0.000001 to 0.01 dtex. When the single fiber diameter exceeds 1000 nm, the dyed fabric does not exhibit a soft texture peculiar to ultrafine fibers, which is not preferable. On the other hand, when the single fiber diameter is less than 10 nm, the fiber strength is lowered, which is not preferable for practical use. 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.
前記ポリエステルフィラメント糸Ａにおいて、フィラメント数は特に限定されないが、超極細繊維特有の風合いを得る上で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、ポリエステルフィラメント糸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 polyester filament yarn A, the number of filaments is not particularly limited, but it is preferably 500 or more (more preferably 2000 to 10,000) in order to obtain a texture peculiar to ultrafine fibers. The total fineness of the polyester 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.
前記ポリエステルフィラメント糸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。単繊維の断面形状も特に限定されず、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 polyester filament yarn A is not particularly limited, but is preferably a long fiber (multifilament yarn). 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.
前記ポリエステルフィラメント糸Ａを形成するポリエステルはジカルボン酸成分とジグリコール成分とから製造される。ジカルボン酸成分としては、主としてテレフタル酸が用いられることが好ましく、ジグリコール成分としては主としてエチレングリコール、トリメチレングリコール及びテトラメチレングリコールから選ばれた１種以上のアルキレングリコールを用いることが好ましい。また、ポリエステルには、前記ジカルボン酸成分及びグリコール成分の他に第３成分を含んでいてもよい。該第３成分としては、カチオン染料可染性アニオン成分、例えば、ナトリウムスルホイソフタル酸；テレフタル酸以外のジカルボン酸、例えばイソフタル酸、ナフタレンジカルボン酸、アジピン酸、セバシン酸；及びアルキレングリコール以外のグリコール化合物、例えばジエチレングリコール、ポリエチレングリコール、ビスフェノールＡ、ビスフェノールスルフォンの１種以上を用いることができる。かかるポリエステルとしては、ポリ乳酸などの生分解性を有するポリエステル、マテリアルリサイクルまたはケミカルリサイクルされたポリエステルであってもよい。また、特開２００４−２７００９７号公報や特開２００４−２１１２６８号公報に記載されているような、特定のリン化合物およびチタン化合物を含む触媒を用いて得られたポリエステルでもよい。さらには、ポリ乳酸やステレオコンプレックスポリ乳酸などの脂肪族ポリエステルであってもよい。該ポリエステルポリマー中には、本発明の目的を損なわない範囲内で必要に応じて、微細孔形成剤、カチオン染料可染剤、着色防止剤、熱安定剤、蛍光増白剤、艶消し剤、着色剤、吸湿剤、無機微粒子が１種または２種以上含まれていてもよい。 The polyester forming the polyester filament yarn A is produced from a dicarboxylic acid component and a diglycol component. As the dicarboxylic acid component, terephthalic acid is preferably used mainly, and as the diglycol component, it is preferable to use one or more alkylene glycols selected from ethylene glycol, trimethylene glycol and tetramethylene glycol. Further, the polyester may contain a third component in addition to the dicarboxylic acid component and the glycol component. Examples of the third component include cationic dye dyeable anion components such as sodium sulfoisophthalic acid; dicarboxylic acids other than terephthalic acid such as isophthalic acid, naphthalenedicarboxylic acid, adipic acid, sebacic acid; and glycol compounds other than alkylene glycol. For example, one or more of diethylene glycol, polyethylene glycol, bisphenol A, and bisphenol sulfone can be used. Such polyester may be biodegradable polyester such as polylactic acid, material recycled or chemically recycled polyester. Moreover, the polyester obtained using the catalyst containing the specific phosphorus compound and titanium compound which are described in Unexamined-Japanese-Patent No. 2004-270097 and 2004-21268 may be sufficient. Furthermore, aliphatic polyesters such as polylactic acid and stereocomplex polylactic acid may be used. In the polyester polymer, a fine pore forming agent, a cationic dye dyeing agent, an anti-coloring agent, a heat stabilizer, a fluorescent whitening agent, a matting agent, as necessary within the range not impairing the object of the present invention, One or two or more colorants, hygroscopic agents, and inorganic fine particles may be contained.
また、前記ポリエステルフィラメント糸Ａが、海成分と島成分とからなる海島型複合繊維の海成分を溶解除去して得られた糸条であることが好ましい。例えばまず、下記のような海島型複合繊維用の海成分ポリマーと島成分ポリマーを用意する。 Further, the polyester filament yarn A is preferably a yarn obtained by dissolving and removing the sea component of the sea-island type composite fiber composed of the sea component and the island component. For example, first, the following sea component polymer and island component polymer for sea-island type composite fibers are prepared.
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、本発明の目的を達成することが困難になる。したがって、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. On the other hand, when the copolymerization amount is 10% by weight or more, it is difficult to achieve the object of the present invention because of its inherently low melt viscosity. Therefore, it is preferable to copolymerize both components within the above range.
一方、島成分ポリマーは、海成分との溶解速度差があればいかなるポリエステルポリマーであってもよいが、前記のように繊維形成性のポリエチレンテレフタレートや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、ステレオコンプレックスポリ乳酸、ポリ乳酸、第３成分を共重合させたポリエステルなどのポリエステルが好ましい。 On the other hand, the island component polymer may be any polyester polymer as long as there is a difference in dissolution rate from the sea component. However, as described above, the fiber-forming polyethylene terephthalate, polytrimethylene terephthalate, polybutylene terephthalate, stereocomplex poly Polyester such as lactic acid, polylactic acid, polyester obtained by copolymerizing the third component is preferred.
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。 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るので１００以上（より好ましくは３００〜１０００）であることが好ましい。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。 The number of islands is preferably 100 or more (more preferably 300 to 1000) because the productivity in the case of producing ultrafine fibers by dissolving and removing sea components increases as the number of islands increases. 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（直径）は、１０〜１０００ｎｍ（好ましくは１００〜８００ｎｍ）の範囲とする必要がある。島成分の径を該範囲内とすることにより、最終的に得られる織物に、単繊維径（単繊維の直径）が１０〜１０００ｎｍのマルチフィラメント糸が含まれることになる。ここで、島成分の断面形状が丸断面以外の異型断面である場合には、外接円の直径を島成分の径とする。なお、島成分の径（直径）は、海島型複合繊維の海成分をアルカリ水溶液で溶解除去したのち、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。 Next, the diameter (diameter) of the island component needs to be in the range of 10 to 1000 nm (preferably 100 to 800 nm). By setting the diameter of the island component within the range, the finally obtained woven fabric includes a multifilament yarn having a single fiber diameter (single fiber diameter) of 10 to 1000 nm. Here, when the cross-sectional shape of the island component is an atypical cross-section other than the round cross-section, the diameter of the circumscribed circle is the diameter of the island component. In addition, the diameter (diameter) of the island component can be measured by dissolving and removing the sea component of the sea-island type composite fiber with an alkaline aqueous solution and then photographing the cross section of the fiber with a transmission electron microscope.
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く、なかでも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、ポリ乳酸、ポリトリメチレンテレフタレート等のポリエステルに好適である。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、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, and particularly suitable for polyesters such as polyethylene terephthalate, polybutylene terephthalate, polylactic acid, and polytrimethylene terephthalate. 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 fast, high-strength 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.
かくして得られた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 type composite fiber thus obtained, 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.
また、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 sea-island type composite fiber, the thickness of the sea component between the islands is 500 nm or less, particularly 20 to 200 nm, and when the thickness exceeds 500 nm, the thick sea component is dissolved and removed. In addition, since the island components are dissolved, not only the homogeneity between the island components is lowered, but also defects such as fuzz and pilling and dyeing spots are likely to occur.
次いで、該海島型複合繊維にアルカリ水溶液処理を施し、海島型複合繊維の海成分をアルカリ水溶液で溶解除去することにより、海島型複合繊維フィラメント糸を単繊維径が１０〜１０００ｎｍのポリエステルマルチフィラメント糸Ａとする。その際、アルカリ水溶液処理の条件としては、濃度３〜４％のＮａＯＨ水溶液を使用し５５〜６５℃の温度で処理するとよい。また、アルカリ水溶液処理は、織物を織成する前でもよいが、織物を織成した後のほうが好ましい。 Next, the sea-island type composite fiber is subjected to an alkaline aqueous solution treatment, and sea components of the sea-island type composite fiber are dissolved and removed with an alkaline aqueous solution, whereby the sea-island type composite fiber filament yarn is a polyester multifilament yarn having a single fiber diameter of 10 to 1000 nm. A. At that time, the alkaline aqueous solution treatment may be performed at a temperature of 55 to 65 ° C. using a 3 to 4% NaOH aqueous solution. The alkaline aqueous solution treatment may be performed before weaving the fabric, but is preferably performed after weaving the fabric.
一方、導電性物質および／または制電性物質を含むフィラメント糸Ｂは、その単繊維径が１０００ｎｍ（１μｍ）より大（好ましくは１．１〜２０μｍ）であることが肝要である。該単繊維径が１０００ｎｍ以下であると、比表面積が大きくなり繊維間の摩擦が大きくなり、優れた制電性が得られず好ましくない。逆に該単繊維径が２０μｍよりも大きいと、超極細繊維が有するピーチタッチ状の独特の風合いが損われるおそれがある。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、前記と同様、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。 On the other hand, it is important that the filament yarn B containing a conductive substance and / or an antistatic substance has a single fiber diameter larger than 1000 nm (1 μm) (preferably 1.1 to 20 μm). When the single fiber diameter is 1000 nm or less, the specific surface area is increased, the friction between the fibers is increased, and an excellent antistatic property cannot be obtained. On the other hand, if the single fiber diameter is larger than 20 μm, the peach touch-like unique texture of the ultrafine fibers may be impaired. 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, as described above.
前記フィラメント糸Ｂにおいて、フィラメント数は特に限定されないが、１〜３００本の範囲内であることが好ましい。また、かかるフィラメント糸Ｂ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。単繊維の断面形状も特に限定されず、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。 In the filament yarn B, the number of filaments is not particularly limited, but is preferably in the range of 1 to 300. The fiber form of the filament yarn B is not particularly limited, but is preferably a long fiber (multifilament yarn). 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Ｂは、布帛に制電性を付加する上で導電性物質および／または制電性物質を含むことが肝要である。ここで導電性物質は、電気抵抗値が１．０Ｅ１０Ω／ｃｍ以下の物質であり、制電性物質は親水基を有する物質である。 It is important that the filament yarn B contains a conductive substance and / or an antistatic substance in order to add antistaticity to the fabric. Here, the conductive substance is a substance having an electric resistance value of 1.0E10 Ω / cm or less, and the antistatic substance is a substance having a hydrophilic group.
前記の導電性物質を含むフィラメント糸としては、ポリエステルフィラメント糸Ａと同様のポリエステルやポリアミドにカーボンブラック等の導電性物質を含有させたポリマーからなる導電性フィラメント糸、ポリエステル繊維やポリアミド繊維にメッキや真空蒸着法によって金属を被覆した金属被覆フィラメント糸、ポリエステル繊維やポリアミド繊維にカーボンブラック等の導電性微粒子が分散された樹脂を被覆した導電性樹脂被覆フィラメント糸などが好適である。 As the filament yarn containing the conductive material, conductive filament yarn made of a polymer in which a conductive material such as carbon black is contained in polyester or polyamide similar to the polyester filament yarn A, polyester fiber or polyamide fiber is plated, A metal-coated filament yarn coated with a metal by a vacuum deposition method, a conductive resin-coated filament yarn coated with a resin in which conductive fine particles such as carbon black are dispersed in polyester fiber or polyamide fiber, and the like are suitable.
一方、制電性物質を含むフィラメント糸としては、ポリオキシアルキレン系ポリエーテル化合物またはポリエーテルエステルアミドを含むフィラメント糸が好ましい。例えば、芳香族ポリエステル１００重量部に対して（ａ）ポリオキシアルキレン系ポリエーテル０．２〜３０重量部および（ｂ）有機イオン性化合物０．０５〜１０重量部を含有してなる制電性ポリエステル成分からなるフィラメント糸や、該制電性ポリエステル成分を芯成分とする芯鞘型フィラメント糸や、両末端にカルボキシル基を有する数平均分子量５００〜５０００のポリアミド（ａ）と数平均分子量１６００〜３０００のビスフェノール類のエチレンオキシド付加物（ｂ）から誘導されたポリエーテルエステルアミドを含有してなる制電性ポリエステル成分からなるフィラメント糸や、該制電性ポリエステル成分を芯成分とする芯鞘型フィラメント糸などが好適である。
なお、フィラメント糸Ｂに前記導電性物質と制電性物質とが両方含まれていてもよいし、複数種類含まれていてもよい。
On the other hand, the filament yarn containing the antistatic substance is preferably a filament yarn containing a polyoxyalkylene polyether compound or polyether ester amide. For example, an antistatic property comprising (a) 0.2 to 30 parts by weight of a polyoxyalkylene polyether and (b) 0.05 to 10 parts by weight of an organic ionic compound with respect to 100 parts by weight of an aromatic polyester. Filament yarn comprising a polyester component, a core-sheath filament yarn having the antistatic polyester component as a core component, a polyamide (a) having a carboxyl group at both ends and a number average molecular weight of 500 to 5000 and a number average molecular weight of 1600 Filament yarn made of antistatic polyester component containing polyether ester amide derived from ethylene oxide adduct (b) of 3000 bisphenols, and core-sheath filament using the antistatic polyester component as a core component Yarn or the like is preferred.
The filament yarn B may contain both the conductive substance and the antistatic substance, or a plurality of kinds.
