Abstract
Description
本発明は、布帛の柔軟な風合いを損なうことなく優れた制電性を有する制電性布帛に関する。さらに詳しくは、導電性繊維が間欠配列され、かつ制電加工処理を施されてなる制電性布帛に関するものである。 The present invention relates to an antistatic fabric having excellent antistatic properties without impairing the soft texture of the fabric. More specifically, the present invention relates to an antistatic fabric in which conductive fibers are intermittently arranged and subjected to antistatic processing.
布帛の用途によっては、布帛の柔軟な風合いを損なうことなく極めて優れた制電性を有することが求められている。例えば、布帛がカーシート用表皮材などとして使用される場合、搭乗者にはかかる布帛との摩擦によって発生する静電気が蓄積される。その結果、搭乗者がノブ等の金属部分に接触すると、蓄積された静電気が一気に放電され、搭乗者に電撃ショックが与えられることがあった。 Depending on the use of the fabric, it is required to have extremely excellent antistatic properties without impairing the soft texture of the fabric. For example, when a fabric is used as a car seat skin material, the passenger accumulates static electricity generated by friction with the fabric. As a result, when the occupant comes into contact with a metal part such as a knob, the accumulated static electricity is discharged at once, and an electric shock may be given to the occupant.
一方、布帛に帯電防止性を付加する方法は、従来種々提案されている。
例えば、特許文献１では、制電組成物を含有する処理剤で布帛を処理することにより、布帛に制電性を付与することが提案されている。しかしながら、かかる方法により得られた制電性布帛は、布帛の柔軟な風合いは損なわれないものの、制電性の点でまだ十分とはいえなかった。
On the other hand, various methods for adding antistatic properties to fabrics have been proposed.
For example,
特許文献２では、導電性微粒子を含む導電性繊維を間欠配列させた制電性布帛が提案されている。しかるに、制電性を高めるためには隣り合う導電性繊維間の間隔をかなり小さくする必要があり、その結果、布帛の柔軟な風合いが損なわれるという問題があった。
また、パイル布帛のバッキング層にカーボンを配合することにより、帯電防止性を付与することも知られているが、布帛の柔軟な風合いが損なわれるだけでなく、材料コストが高くなるという問題があった。
本発明は、上記の背景に鑑みなされたものであり、その目的は、布帛の柔軟な風合いを損なうことなく極めて優れた制電性を有する制電性布帛を提供することにある。 The present invention has been made in view of the above background, and an object of the present invention is to provide an antistatic fabric having extremely excellent antistatic properties without impairing the soft texture of the fabric.
本発明者は、導電性繊維を間欠配列させた布帛に制電加工処理を施すことにより、導電性繊維の制電性効果と制電加工処理による制電性効果とが相乗されて、驚くほど優れた制電性を有する制電性布帛が得られること、しかもかかる制電性布帛において柔軟な風合いを損なわれていないことを見出し、さらに鋭意検討することにより本発明に到達した。 The present inventor has surprisingly realized that the antistatic effect of the conductive fiber and the antistatic effect by the antistatic processing are synergized by applying antistatic processing to the fabric in which the conductive fibers are intermittently arranged. The inventors have found that an antistatic fabric having excellent antistatic properties can be obtained, and that the flexible texture of the antistatic fabric is not impaired, and further intensively studied to arrive at the present invention.
本発明によれば、「主として有機繊維で構成される布帛であって、導電性繊維が経方向および／または緯方向に間欠配列されてなり、かつ制電加工処理が施されてなることを特徴とする制電性布帛。」が提供される。 According to the present invention, “a fabric mainly composed of organic fibers, in which conductive fibers are intermittently arranged in the warp direction and / or the weft direction, and subjected to antistatic processing. "An antistatic fabric".
その際、有機繊維がポリエステル繊維であることが好ましい。一方、導電性繊維としては、カーボンブラックを含有する繊維が好適である。導電性繊維の間欠の間隔は２〜５０ｍｍの範囲内であることが、柔軟な風合いと優れた制電性とを両立させる上で好ましい。導電性繊維の混率は、重量比で３％以下であることが好ましい。布帛がパイル布帛であり、該パイル布帛の地組織部に導電性繊維が経方向および／または緯方向に間欠配列されてなり、かつ該パイル布帛の立毛部に導電性繊維が一部含まれることが好ましい。また、制電加工処理としては、ポリエステル系制電組成物を布帛重量に対して１〜１０重量％付与することが好ましい。制電性としては、人体帯電圧試験法で３０００Ｖ以下であることが好ましい。本発明の制電性布帛は、カーシート用表皮材など極めて優れた制電性を必要とする分野に好適に使用することができる。 In that case, it is preferable that an organic fiber is a polyester fiber. On the other hand, as the conductive fiber, a fiber containing carbon black is suitable. The interval between the conductive fibers is preferably in the range of 2 to 50 mm in order to achieve both a soft texture and excellent antistatic properties. The mixing ratio of conductive fibers is preferably 3% or less by weight. The fabric is a pile fabric, the conductive fibers are intermittently arranged in the warp direction and / or the weft direction in the ground tissue portion of the pile fabric, and the conductive fibers are partially included in the raised portions of the pile fabric. Is preferred. Further, as the antistatic processing, it is preferable to apply 1 to 10% by weight of the polyester antistatic composition with respect to the weight of the fabric. The antistatic property is preferably 3000 V or less according to the human body voltage test method. The antistatic fabric of the present invention can be suitably used in fields that require extremely excellent antistatic properties such as car seat skin materials.
本発明によれば、布帛の柔軟な風合いを損なうことなく極めて優れた制電性を有する制電性布帛が提供される。 ADVANTAGE OF THE INVENTION According to this invention, the antistatic fabric which has the very outstanding antistatic property without impairing the soft texture of a fabric is provided.

本発明の制電性布帛において、導電性繊維が経方向および緯方向の少なくともいずれかの方向に間欠配列されている。 In the antistatic fabric of the present invention, the conductive fibers are intermittently arranged in at least one of the warp direction and the weft direction.
導電性繊維を間欠配列する方法としては、市販のミシン等を用いて、導電性繊維を布帛に縫いこむ方法や、好ましくはあらかじめ布帛に交織、交編する方法が例示される。 Examples of the method of intermittently arranging the conductive fibers include a method of sewing the conductive fibers into a fabric using a commercially available sewing machine or the like, and a method of preferably weaving and knitting the fabric in advance.
例えば、織物の場合、導電性繊維を必要に応じて他の繊維と混繊、撚糸、カバリングした上で、布帛上で等間隔で配列されるように整経で配列させたり、織機上で緯糸の打ち込みを行うことが好ましい。また、編物の場合、給糸する一部の糸を導電糸として編成することが好ましい。なかでも、地組織部と立毛部とからなるパイル織編物が極めて好ましい。地組織部に導電性繊維を間欠配列させ、かつ立毛部に導電性繊維が一部（好ましくは立毛部に混率で０．１〜３重量％）含まれるようにすると、立毛部に含まれる導電糸が人体と接触するため極めて優れた制電性が得られる。 For example, in the case of woven fabrics, conductive fibers are mixed with other fibers as necessary, twisted yarns, covered, and then arranged at regular intervals on the fabric, or wefts on the loom Is preferably performed. In the case of a knitted fabric, it is preferable that a part of the yarn to be fed is knitted as a conductive yarn. Among these, a pile woven or knitted fabric composed of a ground tissue portion and a raised portion is extremely preferable. When the conductive fibers are intermittently arranged in the ground tissue portion and the napped portion contains a part of the conductive fibers (preferably 0.1 to 3 wt% in the mixed portion in the napped portion), the conductivity contained in the napped portion is included. Since the yarn comes into contact with the human body, extremely excellent antistatic properties can be obtained.
導電性繊維の配列される間隔としては、２〜５０ｍｍ（より好ましくは３〜３０ｍｍ）の範囲内であることが好ましい。該間隔が５０ｍｍよりも大きいと、優れた制電性が得られない恐れがある。逆に、該間隔が２ｍｍよりも小さいと、柔軟な風合いが損なわれる恐れがある。 The interval at which the conductive fibers are arranged is preferably in the range of 2 to 50 mm (more preferably 3 to 30 mm). If the distance is larger than 50 mm, there is a possibility that excellent antistatic properties cannot be obtained. On the contrary, if the distance is smaller than 2 mm, the flexible texture may be impaired.
さらに、導電性繊維が含有される割合は、重量比で３％以下（より好ましくは０．１〜２．５％）であることが好ましい。 Furthermore, the ratio of the conductive fibers contained is preferably 3% or less (more preferably 0.1 to 2.5%) by weight.
本発明の制電性布帛は、上記の布帛に制電加工処理を施したものである。かかる制電加工処理としては、通常の制電剤を通常の後加工処理で布帛に付与するものでよい。 The antistatic fabric of the present invention is obtained by subjecting the above fabric to antistatic processing. As such an antistatic processing, an ordinary antistatic agent may be applied to the fabric by an ordinary post-processing treatment.
かかる制電剤としては、例えば、ポリエチレングリコールを親水性成分とし、これをアクリル系やポリエステルにグラフト重合した樹脂タイプの制電剤や、ポリアルキレングリコール（例えば、ポリエチレングリコール）単位（基）と４級アンモニウム塩基などの制電性能を有する官能基を有し、かつ少なくとも２個のイソシアネート基を有する化合物からなる制電加工用ポリウレタン樹脂、特開平１０−３２５０７６号公報に開示されたスルホン酸塩と４級アンモニウム塩とイミダゾリニウム塩とからなる制電剤などが例示される。なかでも、耐久性の点でポリエステル系制電剤が極めて好適である。特に、前記の有機繊維としてポリエステル繊維を選定した場合には優れた耐久性が得られる。 Examples of such antistatic agents include resin-type antistatic agents obtained by graft-polymerizing polyethylene glycol as a hydrophilic component and acrylic polymer or polyester, and polyalkylene glycol (for example, polyethylene glycol) units (groups) and 4 A polyurethane resin for antistatic processing comprising a compound having an antistatic performance such as a secondary ammonium base and having at least two isocyanate groups, and a sulfonate disclosed in JP-A-10-325076 Examples thereof include an antistatic agent comprising a quaternary ammonium salt and an imidazolinium salt. Of these, polyester antistatic agents are extremely suitable from the viewpoint of durability. In particular, when a polyester fiber is selected as the organic fiber, excellent durability can be obtained.
布帛に制電剤を付与する方法としては特に限定されるものではなく、布帛の少なくとも片面に、パデング方式、乾式コーテイング方式、湿式コーテイング方式、ラミネート方式などにより樹脂皮膜を形成する方法や、染色と同浴で制電剤を付与する方法などがあげられる。 The method for applying the antistatic agent to the fabric is not particularly limited, and a method of forming a resin film on at least one side of the fabric by a padding method, a dry coating method, a wet coating method, a laminate method, or the like, For example, a method of applying an antistatic agent in the same bath.
例えば、まず制電剤を含む処理液を準備する。その際、処理液中の制電剤の濃度としては、０．１〜１５ｗｔ％（より好ましくは１〜８ｗｔ％）の範囲が適当である。また、該処理液中には、必要に応じて触媒、仕上げ加工剤、例えば撥水剤、柔軟剤、難燃剤、抗菌防臭加工剤などを添加してもよい。次いで、８０〜１４０℃の温度で１〜３０分乾燥し、必要に応じてさらに１６０〜１８０℃で０．５〜３分間加熱（キュアー）すればよい。 For example, first, a treatment liquid containing an antistatic agent is prepared. At that time, the concentration of the antistatic agent in the treatment liquid is suitably in the range of 0.1 to 15 wt% (more preferably 1 to 8 wt%). Moreover, you may add a catalyst and a finishing agent, for example, a water repellent, a softening agent, a flame retardant, an antibacterial deodorizing agent, etc. in this process liquid as needed. Then, it may be dried at a temperature of 80 to 140 ° C. for 1 to 30 minutes, and further heated (cured) at 160 to 180 ° C. for 0.5 to 3 minutes as necessary.
また、染色と同浴で制電剤を付与する場合は、例えば、有機繊維がポリエステル繊維であるときは通常の分散染料のほか、制電剤、均染剤、ｐＨ調製剤等を含んだ染料水溶液にて１００〜１３５℃で２０〜７０分染色を行う。 In addition, when applying an antistatic agent in the same bath as the dyeing, for example, when the organic fiber is a polyester fiber, in addition to a normal disperse dye, a dye containing an antistatic agent, a leveling agent, a pH adjuster, etc. Dyeing is performed in an aqueous solution at 100 to 135 ° C. for 20 to 70 minutes.
このようにして付与される制電剤の重量％は布帛に対して、１〜１０重量％（より好ましくは２〜６重量％）であることが好ましい。該付着量が１重量％よりも小さいと充分な制電性が得られない恐れがある。逆に、該付着量が１０重量％よりも大きいと、柔軟な風合いが損なわれる恐れがある。 The weight percent of the antistatic agent applied in this manner is preferably 1 to 10% by weight (more preferably 2 to 6% by weight) with respect to the fabric. If the adhesion amount is less than 1% by weight, sufficient antistatic property may not be obtained. On the other hand, if the amount of adhesion is greater than 10% by weight, the soft texture may be impaired.
なお、制電剤を付与する布帛には、必要に応じて減量率５〜４０％程度の通常の減量加工、さらには、常法の吸水加工、撥水加工、起毛加工、シャーリング、さらには、紫外線遮蔽あるいは、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, for the fabric to which the antistatic agent is applied, if necessary, a normal weight reduction process with a weight loss rate of about 5 to 40%, and further a conventional water absorption process, water repellent process, brushed process, shearing, Various processings that impart functions such as ultraviolet shielding or antibacterial agents, deodorants, insect repellents, phosphorescent agents, retroreflective agents, and negative ion generators may be additionally applied.
かくして得られた制電性布帛において、制電性としては、人体帯電圧試験法（試験環境条件：１０℃、３０％ＲＨ）で３０００Ｖ以下（より好ましくは５０〜２６００Ｖ）であることが好ましい。また、摩擦耐電圧で１００Ｖ以下（より好ましくは２〜５０Ｖ）であることが好ましい。このように優れた制電性を有すると、カーシート用表皮材など極めて優れた制電性を必要とする分野に好適に使用することができる。 In the antistatic fabric thus obtained, the antistatic property is preferably 3000 V or less (more preferably 50 to 2600 V) in the human body voltage test method (test environment conditions: 10 ° C., 30% RH). The friction withstand voltage is preferably 100 V or less (more preferably 2 to 50 V). Such excellent antistatic properties can be suitably used in fields that require extremely excellent antistatic properties such as car seat skin materials.
本発明の制電性布帛において、前記導電性繊維が経方向および／または緯方向に間欠配列されており、かつ制電加工処理がほどこされているため、静電気が極めてスムーズに放出される。その結果、優れた制電性が得られ、しかも柔軟な風合いが損なわれることもない。 In the antistatic fabric of the present invention, the conductive fibers are intermittently arranged in the warp direction and / or the weft direction, and the antistatic processing is applied, so that static electricity is discharged very smoothly. As a result, excellent antistatic properties can be obtained, and the flexible texture is not impaired.
