Description
本発明は、防護用の物品に使用される複合糸、及びそれを用いて作製された鉤裂き性及び耐切創性に優れた織編物に関する。 The present invention relates to a composite yarn used for an article for protection, and a woven or knitted fabric made using the same and excellent in tearability and cut resistance.
金属繊維と高強度合成繊維から構成される糸や織編物は、危険な作業において作業者の身体を保護するために使用する作業衣や作業用指サックなどとして広く利用されている。 Yarns and knitted or knitted fabrics composed of metal fibers and high-strength synthetic fibers are widely used as work clothes and work finger sacks used to protect the worker's body in dangerous work.
特公昭５９−２８６４１号公報には、可撓性を有する針金（直径１０２〜１５４μｍ）とそれに密着して並んでいるアラミド繊維ストランドからなるコアと、該コアにアラミド繊維の外被が相互に反対方向にらせん状に巻き付けられているダブルカバリング糸から作製された保護手袋が開示されている（特許文献１参照）。 Japanese Examined Patent Publication No. 59-28641 discloses a core composed of a flexible wire (diameter: 102 to 154 μm) and an aramid fiber strand arranged in close contact with the core, and an outer sheath of the aramid fiber is opposite to the core. A protective glove made from a double covering yarn wound in a spiral shape in a direction is disclosed (see Patent Document 1).
特公平３−６２５４４号公報には、直径約４０μｍの１本のステンレス鋼針金とそれに沿わせた約１３３〜５３１．６デニールの１本のアラミド繊維紡績糸からなるコアと、該コアにアラミド繊維糸、さらにその上にナイロン糸がらせん状に巻き付けられているダブルカバリング糸から作製された作業用指サックが開示されている（特許文献２参照）。 Japanese Examined Patent Publication No. 3-62544 discloses a core made of one stainless steel wire having a diameter of about 40 μm and a single aramid fiber spun yarn of about 133 to 531.6 denier, and an aramid fiber in the core. A working finger sack made of a double covering yarn in which a yarn and a nylon yarn are spirally wound on the yarn is disclosed (see Patent Document 2).
また、特表２００４−５０１２９２号公報には、直径が１０〜１５０μｍの金属繊維コアと、該コアを被覆するアラミドステープルから構成される糸から作製された耐切断性布が開示されている（特許文献３参照）。 In addition, Japanese translations of PCT publication No. 2004-501292 discloses a cut-resistant fabric made from a yarn composed of a metal fiber core having a diameter of 10 to 150 μm and an aramid staple covering the core (patent) Reference 3).
しかしながら、特許文献１に開示されたダブルカバリング糸からなる編物は、直径０．１ｍｍ超という大きな直径をもつ針金とアラミド繊維ストランドからなるコアに、アラミド繊維を巻き付けたものであるため、編成時の作業性が悪く、耐鉤裂き性も劣る。 However, the knitted fabric made of double covering yarn disclosed in Patent Document 1 is made by winding an aramid fiber around a core made of a wire having a large diameter of more than 0.1 mm and an aramid fiber strand. Workability is poor and tear resistance is poor.
また、特許文献２では、指サックに柔軟性を付与するために、特許文献１で使用した金属繊維よりも細い金属繊維を用いているが、それを補強するためのアラミド紡績糸を沿わせたものを芯にしているため、糸の製造工程が煩雑となる。また、上記と同様、編成時の作業性が悪く、耐鉤裂き性に劣る。 Moreover, in patent document 2, in order to give a softness | flexibility to a finger sack, although the metal fiber thinner than the metal fiber used in patent document 1 is used, along with the aramid spun yarn for reinforcing it Since the thing is made a core, the manufacturing process of a thread | yarn becomes complicated. In addition, as described above, workability during knitting is poor and tear resistance is poor.
さらに、特許文献３に開示された糸からなる布帛は、金属繊維をアラミド紡績糸で包んでいるため耐切断性は優れているが、斜め方向から力が加わった場合に紡績糸が切断されやすくなり、そのため鉤裂き性に劣る欠点がある。 Further, the fabric made of yarn disclosed in Patent Document 3 is excellent in cutting resistance because metal fibers are wrapped with aramid spun yarn, but the spun yarn is easily cut when force is applied from an oblique direction. Therefore, there is a disadvantage that the tearability is inferior.
本発明は、かかる従来技術の背景に鑑みてなされたもので、耐切創性と耐鉤裂き性を有する織編物を提供することが可能な複合糸、及びそれを用いて作製された防護用の物品として好適な織編物を提供することを目的とする。 The present invention has been made in view of the background of the prior art, and is a composite yarn capable of providing a woven or knitted fabric having cut resistance and tear resistance, and a protective yarn produced using the composite yarn. An object is to provide a woven or knitted fabric suitable as an article.
本発明者等は、かかる課題を解決するため鋭意検討した結果、直径が３０μｍ以上１００μｍ以下のステンレス鋼繊維フィラメントと、高機能フィラメント糸と、の複合糸を用いることにより、前記課題が解決できることを見出し、本発明に到達した。即ち、前記ステンレス鋼繊維により織編物に柔軟性と耐切創性が付与されると共に、それと複合する糸として紡績糸ではなくフィラメント糸を用いることによって、織編物に鉤裂き性が付与される。さらに、高機能フィラメント糸の加工糸を用いることによって、糸のカバリング性や合撚性が向上し、その結果、製織性および製編性（編み立て性）が良好で、高密度の織編物が得られることを見出した。 As a result of intensive studies to solve such problems, the present inventors have found that the above problems can be solved by using a composite yarn of a stainless steel fiber filament having a diameter of 30 μm or more and 100 μm or less and a high-function filament yarn. The headline, the present invention has been reached. That is, flexibility and cut resistance are imparted to the woven or knitted fabric by the stainless steel fiber, and tearing property is imparted to the woven or knitted fabric by using a filament yarn instead of a spun yarn as a composite yarn. Further, by using the processed yarn of the high-performance filament yarn, the yarn covering property and twisting property are improved. As a result, weaving property and knitting property (knitting property) are good, and a high-density woven or knitted fabric is obtained. It was found that it can be obtained.
すなわち、本発明は、直径が３０μｍ以上１００μｍ以下のステンレス鋼繊維フィラメントのみからなるコアに、原糸の特性として、ＪＩＳ Ｌ １０１３に基づいて測定される引張強度が１０ｃＮ／ｄｔｅｘ以上で、かつ、ＪＩＳ Ｌ １０１３に基づいて測定される引張り弾性率が４００ｃＮ／ｄｔｅｘ以上である高機能フィラメント糸の捲縮糸がらせん状に巻き付けられたカバリング糸であることを特徴とする複合糸を提供する。また、本発明は、該複合糸を用いて作製されたことを特徴とする織編物を提供する。
That is, according to the present invention, a core consisting only of a stainless steel fiber filament having a diameter of 30 μm or more and 100 μm or less has a tensile strength measured based on JIS L 1013 of 10 cN / dtex or more as a property of the raw yarn, and JIS Provided is a composite yarn characterized in that it is a covering yarn in which a crimped yarn of a high-function filament yarn having a tensile elastic modulus measured based on L 1013 of 400 cN / dtex or more is spirally wound. The present invention also provides a woven or knitted fabric characterized by being produced using the composite yarn.
本発明によれば、防護用の物品として好適な、耐切創性と耐鉤裂き性を有する織編物を提供することができる。本発明の織編物からなる防護用の物品を着用することにより、金属片や鋭利な刃物などから身体を保護することが可能になる。 ADVANTAGE OF THE INVENTION According to this invention, the woven / knitted fabric which has a cut resistance and a tear resistance suitable as an article for protection can be provided. By wearing a protective article made of the woven or knitted fabric of the present invention, the body can be protected from a metal piece or a sharp blade.
本発明の複合糸を構成するステンレス鋼繊維フィラメントは、その直径が３０μｍ以上１００μｍ以下のものが用いられる。直径が３０μｍ未満の場合は、耐切創性が不十分となり、一方、直径が１００μｍを超える場合は、糸の製織性および製編性（編み立て性）や織編物の柔軟性に劣る。ステンレス鋼繊維の直径は、好ましくは５０μｍ以上７０μｍ以下である。前記のステンレス鋼繊維フィラメントとしては、長繊維の単糸１本を用いてもよく、長繊維を複数本引き揃えたものや合撚したもの等を用いることもできる。 As the stainless steel fiber filament constituting the composite yarn of the present invention, one having a diameter of 30 μm or more and 100 μm or less is used. When the diameter is less than 30 μm, the cut resistance is insufficient. On the other hand, when the diameter exceeds 100 μm, the weaving property and knitting property (knitting property) of the yarn and the flexibility of the woven or knitted fabric are inferior. The diameter of the stainless steel fiber is preferably 50 μm or more and 70 μm or less. As the stainless steel fiber filament, one single filament of long fiber may be used, or one obtained by arranging a plurality of long fibers or twisted ones may be used.
また、本発明の複合糸を構成する高機能フィラメント糸は、その構成繊維の種類は特に問わないが、本発明の目的を達成するために、高強度かつ高弾性率の高機能フィラメント糸を用いるのが好ましい。かかる高機能フィラメント糸としては、原糸の特性として、ＪＩＳＬ １０１３に基づいて測定される引張強度が１０ｃＮ／ｄｔｅｘ以上、好ましくは１５ｃＮ／ｄｔｅｘ以上であるという高引張特性と、ＪＩＳＬ １０１３に基づいて測定される引張り弾性率が４００ｃＮ／ｄｔｅｘ以上であるという高弾性率とを満足する繊維が好ましく使用される。引張強度が１０ｃＮ／ｄｔｅｘ以上、かつ、引張り弾性率が４００ｃＮ／ｄｔｅｘの高機能フィラメント糸を用いることにより、複合糸に高度の耐屈曲性と耐摩耗性を付与し、また、織編物に耐鉤裂き性を付与することができるからである。 Further, the high-performance filament yarn constituting the composite yarn of the present invention is not particularly limited in the type of the constituent fiber, but in order to achieve the object of the present invention, a high-performance filament yarn having high strength and high elastic modulus is used. Is preferred. As such a high-performance filament yarn, as the properties of the raw yarn, the tensile strength measured based on JISL 1013 is 10 cN / dtex or higher, preferably 15 cN / dtex or higher, and measured based on JISL 1013. A fiber satisfying a high elastic modulus of a tensile elastic modulus of 400 cN / dtex or more is preferably used. By using a high-performance filament yarn having a tensile strength of 10 cN / dtex or more and a tensile elastic modulus of 400 cN / dtex, the composite yarn is imparted with a high degree of bending resistance and wear resistance, and the woven or knitted fabric is resistant to warping. It is because tearability can be provided.
かかる高機能フィラメント糸を構成する素材としては、アラミド繊維、全芳香族ポリエステル繊維（例えば株式会社クラレ製、商品名「ベクトラン」）、ポリパラフェニレンベンゾビスオキサゾール繊維（例えば東洋紡株式会社製、商品名「ザイロン」）、ポリベンズイミダゾール繊維、ポリアミドイミド繊維（例えばローヌプーラン社製、商品名「ケルメル」）、超高分子量ポリエチレン繊維（例えば東洋紡株式会社製、商品名「ダイニーマ」）、ＬＣＰ（液晶ポリマー）繊維などが好ましく使用される。これらの繊維のなかでも、耐切創性に優れている点から、アラミド繊維が特に好ましく使用される。 Examples of the material constituting the high-performance filament yarn include aramid fibers, wholly aromatic polyester fibers (for example, Kuraray Co., Ltd., trade name “Vectran”), polyparaphenylene benzobisoxazole fibers (for example, Toyobo Co., Ltd., trade names) “Zylon”), polybenzimidazole fiber, polyamideimide fiber (for example, Rhône-Poulenc, trade name “Kelmer”), ultrahigh molecular weight polyethylene fiber (for example, Toyobo Co., Ltd., trade name “Dyneema”), LCP (liquid crystal polymer) ) Fibers are preferably used. Among these fibers, an aramid fiber is particularly preferably used because it has excellent cut resistance.
前記アラミド繊維としては、メタ系アラミド繊維とパラ系アラミド繊維があり、メタ系アラミド繊維としては、例えば、ポリメタフェニレンイソフタルアミド繊維（デュポン社製、商品名「ノーメックス」）などのメタ系全芳香族ポリアミド繊維が使用される。また、パラ系アラミド繊維としては、例えば、ポリパラフェニレンテレフタルアミド繊維（東レ・デュポン株式会社製、商品名「ケブラー」）およびコポリパラフェニレン−３，４'−ジフェニルエーテルテレフタルアミド繊維（帝人株式会社製、商品名「テクノーラ」）などのパラ系全芳香族ポリアミド繊維が使用される。これらの中でも、特に、高強度特性および高弾性率とともに耐切創性、耐熱性に優れている点から、パラ系アラミド繊維が好ましく使用される。該アラミド繊維は、公知またはそれに準ずる方法で製造でき、また、上記のような市販品を用いてもよい。 Examples of the aramid fibers include meta-aramid fibers and para-aramid fibers. Examples of the meta-aramid fibers include meta-total aroma such as polymetaphenylene isophthalamide fiber (manufactured by DuPont, trade name “NOMEX”). Group polyamide fibers are used. Examples of the para-aramid fiber include polyparaphenylene terephthalamide fiber (trade name “Kevlar” manufactured by Toray DuPont Co., Ltd.) and copolyparaphenylene-3,4′-diphenyl ether terephthalamide fiber (manufactured by Teijin Limited). Para-type wholly aromatic polyamide fibers such as “Technola”) are used. Among these, para-aramid fibers are particularly preferably used because they are excellent in cut resistance and heat resistance as well as high strength characteristics and high elastic modulus. The aramid fiber can be produced by a known method or a method equivalent thereto, or a commercially available product as described above may be used.
かかる高機能フィラメント糸は、糸のカバリング性や撚り性に優れると共に、織編物を形成したときの風合いがソフトであり、さらに伸縮性に優れるという観点から、高機能フィラメント糸に仮撚り加工を施した捲縮糸が、好ましく使用される。捲縮糸は、仮撚り加工（加撚→熱セット→解撚）まで加工していない加撚、熱セットのみのものや、仮撚り加工した糸を撚糸したもの、仮撚り加工した糸に熱セットをしたもの、または撚糸した糸を仮撚り加工したものであっても良い。
Such a high-performance filament yarn is excellent in yarn covering and twisting properties, has a soft texture when forming a woven or knitted fabric, and is further excellent in stretchability. The crimped yarn is preferably used. Crimped yarns are not twisted (tempered → heat set → untwisted) until twisted, heat set only, false twisted yarn twisted, false twisted yarn A set or a twisted yarn may be false twisted.
かかる高機能フィラメント糸に捲縮を付与する方法としては、例えば、特開２００１−２４８０２７号公報に開示されているように、高機能フィラメント糸に下記式（１）で表わされる撚り係数（Ｋ）１６，０００〜３５，０００の撚りを加え、次いで１３０〜２５０℃の高温高圧水蒸気または高温高圧水処理を行って撚りを固定し、撚りの固定された撚り糸を前記と反対方向に撚りを解撚する方法がある。 As a method for imparting crimp to such a high-performance filament yarn, for example, as disclosed in Japanese Patent Application Laid-Open No. 2001-248027, the high-function filament yarn has a twist coefficient (K) represented by the following formula (1). Add 16,000 to 35,000 twist, then perform high-temperature high-pressure steam or high-temperature high-pressure water treatment at 130 to 250 ° C to fix the twist, and untwist the twisted yarn in the opposite direction. There is a way to do it.
Ｋ＝ｔ×Ｄ１／２ （１）
〔但し、ｔは撚り数（回／ｍ）を表し、Ｄは繊度（ｄｔｅｘ）を表す。〕
K = t × D 1/2 (1)
[However, t represents the number of twists (times / m), and D represents the fineness (dtex). ]
また、パラ系アラミド繊維フィラメント捲縮糸条は、つぎの方法でも得られる。すなわち、パラ系アラミド繊維糸条に下記式（２）で表される撚り係数（Ｋ）１６，０００〜３５，０００の撚りを加え、次いで例えば空気中で加熱などの方法を用いて乾燥することにより、撚りを固定した後、撚りの固定された撚り糸を前記と反対方向に解撚することによって得られる。このとき、該パラ系アラミド繊維として、好ましくは水分率１５％以上、より好ましくは２５％以上、特に好ましくは３０〜１００％であるものを使用するのがよい。該パラ系アラミド繊維に撚りを加える前の水分率が１５％未満では、良好な撚りのセット効果が得られず、一方撚りを加える前の水分率が１００％を越えると、リング撚糸機やダブルツイスターで撚りをかけるときに、遠心力で糸条から水分が飛び散って撚糸機が水浸しになるなど環境や作業性に支障をきたす。
Para-aramid fiber filament crimped yarn can also be obtained by the following method. That is, a twist of a twist coefficient (K) of 16,000 to 35,000 represented by the following formula (2) is added to the para-aramid fiber yarn, and then dried using a method such as heating in the air. Accordingly, after fixing the twist, it is obtained by untwisting a fixed yarn twist in the opposite direction as the. At this time, as the para-aramid fiber, one having a moisture content of preferably 15% or more, more preferably 25% or more, and particularly preferably 30 to 100% may be used. If the moisture content before twisting the para-aramid fiber is less than 15%, a good twist setting effect cannot be obtained. On the other hand, if the moisture content before twisting exceeds 100%, a ring twisting machine or double When twisting with a twister, water is scattered from the yarn by centrifugal force, and the twisting machine is immersed in water, which hinders the environment and workability.
Ｋ＝ｔ×Ｄｗ１／２ （２）
〔但し、ｔは撚り数（回／ｍ）を表し、Ｄｗは水分を含む繊度（ｄｔｅｘ）を表す。〕
K = t × Dw 1/2 (2)
[However, t represents the number of twists (times / m), and Dw represents the fineness (dtex) including moisture. ]
かかる高機能フィラメント捲縮糸の伸縮復元率は、望ましくは４〜８０％である。伸縮復元率が４％未満では、織編物を形成したときの風合いにおいてソフト感が劣り、また８０％以上ではステンレス鋼繊維との調和が悪く、カバリング糸の外観に凹凸が発生して好ましくない。また、残留トルク撚り数は、２０回／ｍ以上が好ましい。 The stretch recovery rate of such highly functional filament crimped yarn is desirably 4 to 80%. If the expansion / contraction restoration rate is less than 4%, the soft feeling is inferior when the woven or knitted fabric is formed, and if it is 80% or more, the harmony with the stainless steel fibers is poor and the appearance of the covering yarn is not preferable. The residual torque twist number is preferably 20 times / m or more.

本発明の複合糸は、ステンレス鋼繊維フィラメントと高機能フィラメント糸を、重量比で５：９５〜７５：２５の範囲で用いたものが好ましい。ステンレス鋼繊維の比率が少なすぎる場合は、織編物の耐切創性が不十分となり、一方、高すぎる場合は、布地が堅くなる。より好ましくは、重量比で２５：７５〜６０：４０の範囲である。 The composite yarn of the present invention is preferably one in which a stainless steel fiber filament and a highly functional filament yarn are used in a weight ratio of 5:95 to 75:25. If the ratio of stainless steel fibers is too small, the cut resistance of the woven or knitted fabric will be insufficient, while if too high, the fabric will be stiff. More preferably, the weight ratio is in the range of 25:75 to 60:40.
複合糸がカバリング糸である場合、ステンレス鋼繊維単糸に高機能フィラメント糸をらせん状に一重に巻き付けたもの（ＳＣＹ：シングル・カバード・ヤーン）であってもよく、また、優れた被覆性を得る観点からさらにその上に、高機能繊維、ナイロン繊維、ポリエステル繊維などの合成繊維や、天然繊維などの他の公知の繊維をらせん状に巻き付け、ステンレス鋼繊維の回りを二重（ＤＣＹ：ダブル・カバード・ヤーン）もしくは三重に被覆したものであってもよい。 When the composite yarn is a covering yarn, it may be a single thread (SCY: single covered yarn) in which a high-performance filament yarn is wound in a single spiral on a stainless steel fiber single yarn. Furthermore, from the viewpoint of obtaining, other known fibers such as high-performance fibers, nylon fibers, and polyester fibers, and natural fibers are spirally wound around the stainless steel fibers (DCY: double). -Covered yarn) or triple-coated one.

実施例と比較例の編物の特性を表１に示す。なお、下記表中の物性は次のようにして測定した。 Table 1 shows the characteristics of the knitted fabrics of Examples and Comparative Examples. The physical properties in the following table were measured as follows.
［鉤裂き性試験］
ＩＳＯ１３９９５「防護服−機械的特性−材料の突刺及び動的引裂に対する抵抗性試験法」に準拠した。落下刃物に対して垂直方向に取り付けられた試験片面に刃物取付落下重錘を一定距離から落下させ、重錘衝撃エネルギーによって試験片に発生する引裂長（鉤裂け長さ）を測定した。鉤裂き方向は、ウエル方向、コース方向で実施した。性能判定は、鉤裂け長さが４０ｍｍ以内のとき「合格」とした。刃物保持ブロックと刃物の質量は１０００ｋｇ、衝撃エネルギーは７Ｊで実施した。
[Tearability test]
In accordance with ISO 13995 “Protective garments—Mechanical properties—Test method for resistance to material piercing and dynamic tearing”. The blade-attached falling weight was dropped from a certain distance onto the surface of the test piece attached in a direction perpendicular to the falling blade, and the tear length (tearing length) generated in the test piece by the weight impact energy was measured. The tearing direction was the well direction and the course direction. The performance judgment was “pass” when the tear length was within 40 mm. The mass of the blade holding block and the blade was 1000 kg, and the impact energy was 7 J.
［耐切創性試験］
ＩＳＯ１３９９７「防護服−機械的特性−鋭利物に対する切創抵抗性試験方法」に準拠し、切創抵抗値を測定した。カット方向は４５度方向とした。表中の耐切創性は、次式により求められる値である。耐切創性＝（切創抵抗値／目付）×１００
[Cut resistance test]
The cut resistance value was measured in accordance with ISO 13997 “Protective clothing—mechanical characteristics—cutting resistance test method for sharp objects”. The cutting direction was a 45 degree direction. The cut resistance in the table is a value determined by the following formula. Cut resistance = (cut resistance / weight) × 100
表１から明らかなように、本発明に係る複合糸を使用した織編物は、耐鉤裂き性が合格レベルにあり、耐切創性にも優れていた。一方、ステンレス鋼繊維フィラメントとポリエステルフィラメントからなる複合糸を使用した織編物は、耐鉤裂き性及び耐切創性が不十分であった。また、ステンレス鋼繊維フィラメントを複合していないアラミド繊維捲縮糸を使用した織編物は、耐鉤裂き性は合格レベルに近いが、耐切創性が不十分であった。以上の結果から、ステンレス鋼繊維フィラメントと高機能フィラメント糸との複合糸を使用することにより、耐鉤裂き性と耐切創性をともに満足する織編物が得られることがわかる。
As is apparent from Table 1, the woven or knitted fabric using the composite yarn according to the present invention has an acceptable tear resistance and an excellent cut resistance. On the other hand, a woven or knitted fabric using a composite yarn composed of stainless steel fiber filaments and polyester filaments has insufficient tear resistance and cut resistance. In addition, the woven or knitted fabric using the aramid fiber crimped yarn not combined with the stainless steel fiber filament has a tear resistance close to an acceptable level, but has an insufficient cut resistance. From the above results, it is understood that a woven or knitted fabric satisfying both tear resistance and cut resistance can be obtained by using a composite yarn of a stainless steel fiber filament and a highly functional filament yarn.
Claims (6)
