Description

本発明は、マルチフィラメントからなる繊維製品及びその製造方法に係り、詳しくは、静電気の帯電を十分に抑制し、且つ風合い及びデザイン性を損なわない繊維製品及びその製造方法に関する。   The present invention relates to a fiber product composed of multifilaments and a method for producing the same, and more particularly, to a fiber product that sufficiently suppresses electrostatic charging and does not impair the texture and design and a method for producing the same.

近年、スポーツ、アウトドアー衣料分野に高級感や高付加価値が重視され、マルチフィラメントを使用した製品の開発が増えている。しかし、これらのマルチフィラメントを用いた高密度製品は、独自の柔らかな風合いと、通気性、防水性等の機能を有するあまりに、通常の繊維からなる製品に比べ、同一領域内では遥かに表面積を有するため、塵埃等が付着し易くなり、加えて接触面積が増えるため静電気も発生し易く、両者が相まって、マルチフィラメントを表層部に用いた衣料等は汚れ易く、また一旦塵埃が付着するとこれを除去することが難しい。   In recent years, luxury and high added value are emphasized in the sports and outdoor clothing fields, and the development of products using multifilaments is increasing. However, these high-density products using multifilaments have unique soft textures and functions such as breathability and waterproofness, so they have much more surface area in the same area than products made of ordinary fibers. Because of this, dust and the like easily adhere to it, and since the contact area increases, static electricity is also likely to occur. Difficult to remove.

また、このような製品を身につけていると、静電気が帯電して、何気なくドアの金具や手すり等の金属製品に手を触れた時に衝撃を受けたり、衣類がまとわりついたり、重ね着をしていた衣類を脱ぐ時にパチパチ音がして衝撃を受ける等、不快な思いをすることが多い。   Also, if you wear such products, you will be charged with static electricity, and you will be suddenly touched by metal objects such as door fittings and handrails. Many people feel uncomfortable, for example, they make a crackling noise when taking off their clothes.

上記のような静電気の帯電に起因する現象を抑制する一般的な方法としては、周りの湿度を50%以上に維持することや、衣類に静電気帯電抑制液を塗る等の表面加工を施す方法等が知られているが、後加工処理では洗濯耐久性が無く、永続的に静電気の帯電を抑制することは困難であった。   As a general method of suppressing the phenomenon caused by the electrostatic charge as described above, a method of performing surface processing such as maintaining the surrounding humidity at 50% or more, or applying an electrostatic charge suppressing liquid to clothing, etc. However, in post-processing, there is no washing durability, and it is difficult to suppress static charge permanently.

このような欠点を改良するため、導電性繊維が製品の表層部で環やたるみを形成した製品が知られている(特許文献1参照)。これらの製品は、抜群な静電気抑制性能を有するが、導電性繊維が目立ってしまい、ファッション性の要求される高級衣料分野には応用しにくい。   In order to improve such a defect, a product in which conductive fibers form a ring or a slack in the surface layer portion of the product is known (see Patent Document 1). Although these products have outstanding static electricity suppressing performance, conductive fibers are conspicuous and are difficult to apply in the high-grade clothing field where fashionability is required.

また、静電気の帯電を抑制したネクタイが知られている(特許文献2参照)。しかし、このようなネクタイは特別な構造を必要とし、デザインの汎用性が狭まるという欠点がある。また、導電性繊維が製品の裏面に露出するように取り付けられており、この製品が別の大きな導電体―例えば人体の素肌―に密着した場合、導電層と人体が電気的に一体化した導電体となり、導電性繊維の帯電抑制原理であるコロナ放電の効果が消失する欠点があるため、衣料分野には適用できない。   Also, a tie that suppresses electrostatic charging is known (see Patent Document 2). However, such a tie requires a special structure and has a drawback that the versatility of the design is narrowed. Also, conductive fibers are attached so that they are exposed on the back of the product. When this product is in close contact with another large conductor, such as the bare skin of the human body, the conductive layer and the human body are electrically integrated. It becomes a body and has the disadvantage that the effect of corona discharge, which is the principle of suppressing the charging of conductive fibers, disappears, so it cannot be applied to the clothing field.

一方、化学的に金属メッキされた導電性織物により形成された静電気ショック抑制用ハンカチーフが知られている(特許文献3参照)。しかし、この方法では、ホルマリン水溶液を始め、特別な化学処理が必要であり、金属メッキ処理を施すため、合成繊維の風合いの良さが損なわれる。   On the other hand, a handkerchief for electrostatic shock suppression formed by a conductive metal-plated conductive fabric is known (see Patent Document 3). However, this method requires a special chemical treatment such as a formalin aqueous solution, and a metal plating treatment is performed, so that the quality of the synthetic fiber is impaired.

本発明はかかる問題点を解決するものであって、その目的は、マルチフィラメントの風合いを十分に生かし、ファッションの多様性のニーズに十分に応え得ると共に、静電気帯電による現象を十分に抑制する繊維製品及びその製造方法を提供することにある。   The present invention solves such problems, and its purpose is to make full use of the texture of multifilaments, sufficiently satisfy the needs of fashion diversity, and sufficiently suppress the phenomenon caused by electrostatic charging. It is to provide a product and a manufacturing method thereof.

本発明の目的は、導電性繊維と単糸繊度2.0デシテックス以下のマルチフィラメントとからなる混繊糸を用いた繊維製品であって、該導電性繊維が混繊糸の内層にあることを特徴とする繊維製品によって達成される。   An object of the present invention is a fiber product using a mixed yarn composed of conductive fibers and multifilaments having a single yarn fineness of 2.0 dtex or less, and the conductive fibers are in the inner layer of the mixed yarn. Achieved by the featured textile.

また、本発明の目的は、導電性繊維と単糸繊度2.0デシテックス以下のマルチフィラメントとを用いて気体乱流処理を施し、混繊糸(I)を得た後、更に、得られた混繊糸(
I)とマルチフィラメントとを用いて気体乱流処理を施して混繊糸(II)を得、該混繊
糸(II)を用いて繊維製品を形成することを特徴とする繊維製品の製造方法によって達成される。
The object of the present invention was further obtained after conducting gas turbulent flow treatment using conductive fibers and multifilaments having a single yarn fineness of 2.0 dtex or less to obtain mixed yarn (I). Blended yarn (
I) and a multifilament are used for turbulent gas treatment to obtain a mixed yarn (II), and a fiber product is formed using the mixed yarn (II). Achieved by:

本発明によれば、導電性繊維を用いているにもかかわらず、外見上通常のマルチフィラメントからなる繊維製品との判別は不可能であり、製品としてのデザイン性、風合い等の商品価値は良好で、また、着用・使用時にも何の違和感もない繊維製品が得られる。すなわち、マルチフィラメントによる柔軟な風合いや通気性を生かしたままの、従来の製品と変わらない繊維製品であり、更に、導電性が付与されており、静電気帯電による現象を十分に抑制する繊維製品が得られる。   According to the present invention, despite the use of conductive fibers, it is impossible to discriminate from ordinary fiber products made of multifilaments, and the product value such as design and texture as products is good. In addition, a fiber product without any discomfort when worn or used can be obtained. In other words, it is a fiber product that does not differ from conventional products, taking advantage of the flexible texture and air permeability of multifilaments, and furthermore, a fiber product that is imparted with conductivity and sufficiently suppresses the phenomenon caused by electrostatic charging. can get.

本発明に係るマルチフィラメントは、単糸繊度が2.0デシテックス以下、好ましくは1.5デシテックス以下である。このような単糸繊度を有すると、糸の伸びの回復率や風合いが良くなる。
また、マルチフィラメントの総繊度は、20〜100デシテックスが好ましい。
The multifilament according to the present invention has a single yarn fineness of 2.0 dtex or less, preferably 1.5 dtex or less. With such a single yarn fineness, the recovery rate and texture of the yarn are improved.
The total fineness of the multifilament is preferably 20 to 100 dtex.

また、マルチフィラメントは、直接細繊度繊維を紡糸し、その強度が2.5cN/dTex以上、伸度が25%以上であることが好ましい。この強度未満では、織編物としたときの強度が不足し、高いレベルの物が得られにくい。また、使用する繊維の強度が大きければ、織編物の引裂強度は高くなるが、経糸の毛羽が多くなり、よって、停台が多くなるという問題があり、操業性が悪くなる傾向にある。従って、強度を大きくすると共に、伸度をより好ましくは30%以上、更に好ましく30〜50%の範囲とするのが良い。   In addition, it is preferable that the multifilament is obtained by directly spinning a fine fiber and has a strength of 2.5 cN / dTex or more and an elongation of 25% or more. If it is less than this strength, the strength of the knitted or knitted fabric is insufficient, and it is difficult to obtain a high-level product. Moreover, if the strength of the fiber used is high, the tear strength of the woven or knitted fabric increases, but there is a problem that warp of the warp increases, resulting in an increase in the number of stops, and the operability tends to deteriorate. Therefore, the strength is increased and the elongation is more preferably 30% or more, and further preferably 30 to 50%.

マルチフィラメントの素材は、ナイロン、ポリエステル等適宜使用可能であるが、ナイロンを用いると柔らかい風合いの繊維製品が得られ、好適である。   As the multifilament material, nylon, polyester, or the like can be used as appropriate. However, when nylon is used, a fiber product with a soft texture is obtained, which is preferable.

次に、本発明で用いる導電性繊維としては、コロナ放電による静電気エネルギーの放出を行うもので、電気比抵抗を1013Ωcm以下としたものが好ましい。
また、その単糸繊度が0.5デシテックス以上のものが好ましく、衣料用途に用いる場合、1.0〜4・0デシテックス程度のものが好適である。
Next, the conductive fiber used in the present invention is one that discharges electrostatic energy by corona discharge, and preferably has an electrical specific resistance of 10 13 Ωcm or less.
Moreover, the thing whose single yarn fineness is 0.5 dtex or more is preferable, and when using it for the clothing use, a thing of about 1.0-4.0 dtex is suitable.

このような導電性繊維としては、アクリル、ナイロン等の合成繊維に硫化銅を結合させた有機導電性繊維、イオン伝導性高分子からなる繊維、ステンレス繊維、銅合金繊維等の金属繊維を含む繊維、銀や銅等の金属被膜繊維、導電性カーボンブラック粒子を含有する繊維、導電性被膜を有する粒子を含有する繊維を使用することが出来、電気を通す性質の繊維であれば、種類を問わず使用することが出来る。中でも、カーボンブラック粒子を含有する高分子層を一部に含む長繊維からなる複合繊維または導電性被膜を有する粒子を含有する高分子層を一部に含む長繊維からなる複合繊維が優れた導電性や放電速度を持つため特に好ましい。   Examples of such conductive fibers include organic conductive fibers in which copper sulfide is bonded to synthetic fibers such as acrylic and nylon, fibers made of ion conductive polymers, fibers containing metal fibers such as stainless fibers and copper alloy fibers. , Metal coated fibers such as silver and copper, fibers containing conductive carbon black particles, fibers containing particles having a conductive coating can be used, and any fiber can be used as long as it is a fiber that conducts electricity. Can be used. Among them, a composite fiber composed of a long fiber partially including a polymer layer containing carbon black particles or a composite fiber composed of a long fiber partially including a polymer layer including particles having a conductive coating is excellent in conductivity. It is particularly preferable because of its properties and discharge rate.

カーボンブラック粒子を含有する高分子層を一部に含む長繊維からなる複合繊維としては、非導電性繊維であるナイロン等の高分子からなる層を外層とし、導電性であるカーボンブラック粒子を含有する高分子層を内層とし、芯鞘状の繊維に成形し、カーボンブラック粒子を含有する高分子層からなる内層の少なくとも一部が外部に露出して導電性が得られるように紡糸した複合繊維等が挙げられる。また、カーボンブラック粒子は、カーボンブラック粒子を含有する高分子の層に15〜80質量%含有することが好ましい。   As a composite fiber composed of long fibers partially containing a polymer layer containing carbon black particles, a non-conductive fiber layer such as nylon is used as an outer layer, and conductive carbon black particles are contained. A composite fiber which is formed into a core-sheath fiber, and is spun so that at least a part of the inner layer composed of a polymer layer containing carbon black particles is exposed to the outside and is electrically conductive Etc. Moreover, it is preferable to contain 15-80 mass% of carbon black particles in the polymer layer containing carbon black particles.

一方、導電性被膜を有する粒子とは、酸化チタン粒子が最も好ましく、酸化銅、酸化銀、酸化亜鉛等の導電性を有する金属酸化物で酸化チタン粒子を被膜したものをいう。   On the other hand, the particles having a conductive coating are most preferably titanium oxide particles, which are obtained by coating titanium oxide particles with a conductive metal oxide such as copper oxide, silver oxide or zinc oxide.

また、それらの金属酸化物に、必要に応じて第二成分を配合することもできる。第二成分としては、異種金属の酸化物又は/及び同種・異種金属などを使用することができる。例えば、金属酸化物として酸化銅を使用する場合は、第二成分として銅を添加することができ、金属酸化物として酸化亜鉛を使用する場合は、第二成分として亜鉛を添加することが好ましい.。   Moreover, a 2nd component can also be mix | blended with those metal oxides as needed. As the second component, oxides of different metals or / and the same or different metals can be used. For example, when using copper oxide as the metal oxide, copper can be added as the second component, and when using zinc oxide as the metal oxide, it is preferable to add zinc as the second component. .

上記酸化チタン粒子を金属酸化物や被膜する方法としては、真空にて蒸着させる方法や、有機酸塩等で金属酸化物を付着させ、焼成して酸化物にすることや、それを部分還元することで形成する方法が挙げられる。   As a method of coating the titanium oxide particles with a metal oxide, a method of depositing in vacuum, a method of depositing a metal oxide with an organic acid salt, etc., baking it to an oxide, or partially reducing it The method of forming by this is mentioned.

このような導電性のカーボンブラック粒子を含有する長繊維からなる複合繊維または導電性被膜を有する酸化チタン粒子を含有する長繊維からなる複合繊維としては、カネボウ合繊(株)製ベルトロン(商標)等が挙げられる。これを使用することにより優れた導電性を持った繊維製品が得られる。   Examples of the composite fiber composed of long fibers containing such conductive carbon black particles or the composite fiber composed of long fibers containing titanium oxide particles having a conductive coating include Beltron (trademark) manufactured by Kanebo Synthetic Co., Ltd. Is mentioned. By using this, a fiber product having excellent conductivity can be obtained.

本発明の混繊糸は、前記マルチフィラメントと導電性繊維とからなるものであり、この風合いを大きく変化させない限り若干の第三成分繊維を含むことを妨げない。
混繊方法は種々のものが使われているが、本発明では特に流体乱流処理、いわゆるエアー交絡加工を施したものが好ましい。流体乱流処理により形成される混繊糸の構造は、混繊糸の成分の導電性繊維が混繊糸の内層にある。すなわち、導電性繊維がマルチフィラメントに覆われ、芯鞘構造を取っている。このような構造は、単なる合糸や所謂インターレース処理等による混繊では得ることができないものである。
The blended yarn of the present invention is composed of the multifilament and the conductive fiber, and does not prevent some third component fibers from being included unless the texture is greatly changed.
Various methods for mixing fibers are used, but in the present invention, those subjected to fluid turbulence treatment, so-called air entanglement processing are particularly preferable. In the structure of the blended yarn formed by the fluid turbulent treatment, the conductive fiber as a component of the blended yarn is in the inner layer of the blended yarn. That is, the conductive fiber is covered with a multifilament and has a core-sheath structure. Such a structure cannot be obtained by simple fiber mixing or so-called interlace treatment.

本発明の繊維製品は、織物、編物、不織布等のいずれであっても良く、その組織も特に限定されない。繊維製品は、高密度にすることによって、上記導電性混繊糸の分布密度が増加し、静電気帯電の抑制効果が上がるため、織物においてはカバーファクターで1500〜3000程度、編物においては編密度で1500〜5000程度、その他のものではこれに準じた密度を有していることが好ましい。
また、繊維製品中の導電性繊維量は、0.1質量%以上とすることが好適である。
The textile product of the present invention may be any one of woven fabric, knitted fabric, non-woven fabric and the like, and its structure is not particularly limited. By increasing the density of the fiber product, the distribution density of the conductive mixed yarn increases, and the effect of suppressing electrostatic charging increases. Therefore, the cover factor is about 1500 to 3000 in the woven fabric, and the knitting density is in the knitted fabric. It is preferable that it has a density according to this about 1500 to 5000 and others.
Moreover, it is suitable that the amount of conductive fibers in the fiber product is 0.1% by mass or more.

次に、本発明の製造方法について説明する。まず、マルチフィラメントと導電性繊維とをエアー交絡加工して混繊糸(I)を得る。得られた混繊糸(I)において、環やたるみ
を形成している繊維の主体が導電性繊維であれば、静電気を抑制するには良いが、製品のデザイン性を損なう。従って、この混繊糸(I)を芯糸とし、マルチフィラメントを鞘部
に使用して再度エアー交絡加工し、混繊糸(II)を得る。
このようにすることで、導電性繊維が混繊糸の内層に存在し、目立たなくなり、デザイン性を損なうことなく静電気帯電抑制効果を有する混繊糸を得ることができる。
エアー交絡加工を施して得られた混繊糸(II)は、必ずしも環やたるみが顕在化している必要はなく、製織編性等を考慮すれば、環やたるみは潜在化しているものが好ましい。
また、本発明において、エアー交絡加工の1回目と2回目とに用いるマルチフィラメントは、同種でも、異種でもよい。
Next, the manufacturing method of this invention is demonstrated. First, the multifilament and the conductive fiber are air entangled to obtain a mixed yarn (I). In the obtained mixed yarn (I), if the main fiber forming the ring or sagging is a conductive fiber, it is good for suppressing static electricity, but it impairs the design of the product. Accordingly, the mixed yarn (I) is used as a core yarn, and the multifilament is used for the sheath portion and air entangled again to obtain the mixed yarn (II).
By doing in this way, a conductive fiber exists in the inner layer of a mixed fiber, becomes inconspicuous, and can obtain the mixed fiber which has an electrostatic charge suppression effect, without impairing a design property.
In the mixed yarn (II) obtained by performing the air entanglement processing, it is not always necessary to reveal the ring and the slack, and it is preferable that the ring and the slack are latent in consideration of weaving and knitting. .
In the present invention, the multifilaments used for the first and second air entanglement processing may be the same or different.

上記混繊糸(I)及び(II)において、芯鞘の比率は、それぞれ0.3〜4:1、特
に0.5〜2:1であることが好ましい。
また、エアー交絡加工するにあたって、各加工における鞘糸のオーバフィード率は、好ましくは15〜50%、より好ましくは20〜40%、芯糸のオーバフィード率は、好ましくは5〜20%、より好ましくは7〜15%である。
芯鞘の比率及びオーバフィード率が前記範囲を逸脱すると、強度が低下し、エアー交絡性や糸の伸びの回復率や風合いが悪くなる傾向にある。
In the mixed yarns (I) and (II), the ratio of the core-sheath is preferably 0.3-4: 1, particularly 0.5-2: 1.
Further, in the air entanglement processing, the overfeed rate of the sheath yarn in each processing is preferably 15 to 50%, more preferably 20 to 40%, and the overfeed rate of the core yarn is preferably 5 to 20%. Preferably it is 7 to 15%.
When the ratio of the core-sheath and the overfeed rate deviate from the above ranges, the strength decreases, and the air entanglement property, the recovery rate of the yarn elongation, and the texture tend to be deteriorated.

次に、得られた混繊糸を用いて繊維製品とする。混繊糸は織編物の場合、経緯どちらに用いてもよいが、緯糸に用いることが、他の糸と自由に組み合わせることができ、織り柄を種々選択できる点で好適である。   Next, it is set as a textile product using the obtained mixed yarn. In the case of a woven or knitted fabric, the blended yarn may be used for either the warp or the weft, but it is preferable to use it for the weft because it can be freely combined with other yarns and various woven patterns can be selected.

本発明の繊維製品は、静電気帯電抑制効果を有し、これは単に制電性繊維又は導電性繊維と交織、交編等を行った製品に比べても性能を落とさないものである。同量の導電性繊維を混用するとしても、マルチフィラメントとできるだけ均一に混用されている方が繊維製品の静電気エネルギーの除去にとって有効である。よって、混繊による混用が有効であるが、単に両者を混繊したのでは、導電性繊維の静電気帯電抑制の効力を得ることができないマルチフィラメントが存在し、マルチフィラメントの摩擦による静電気帯電を有効に抑制できない。   The textile product of the present invention has an electrostatic charge suppressing effect, which does not deteriorate the performance as compared with a product obtained by simply knitting or knitting with antistatic fibers or conductive fibers. Even if the same amount of conductive fiber is mixed, it is more effective to remove the electrostatic energy of the fiber product if it is mixed with the multifilament as uniformly as possible. Therefore, mixing by blending is effective, but there are multifilaments that cannot obtain the effect of suppressing electrostatic charging of conductive fibers by simply mixing both, and electrostatic charging by friction of multifilaments is effective. Cannot be suppressed.
