Description
本発明は、高密度袋織基布の製織方法に関するものであり、この高密度袋織基布は、自動車など乗物用の安全装置の一つであるエアバッグに好適に使用することができる。 The present invention relates to a method for weaving a high-density bag-woven base fabric, and the high-density bag-woven base fabric can be suitably used for an airbag that is one of safety devices for vehicles such as automobiles.
近年、自動車等の乗物において、乗員の安全性の向上が求められており、エアバッグの装着率が向上している。エアバッグは、乗物が正面衝突や側面衝突時に受ける衝撃をセンサーが感知し、インフレーターからガスを膨張可能な袋部に流入させ、エアバッグを急速に展開・膨張させて、そのクッション性によって乗員を保護するものである。 2. Description of the Related Art In recent years, in vehicles such as automobiles, improvement of passenger safety has been demanded, and the mounting rate of airbags has been improved. The airbag detects the impact that the vehicle receives during a frontal collision and side collision, and flows the gas from the inflator into the inflatable bag, rapidly deploying and inflating the airbag, and cushioning the occupant It is something to protect.
従来のエアバッグは、運転席や助手席の前面部に装着されることが多く、主に正面衝突時における乗員の顔面および上半身の保護用として多く装着されていたが、最近では側方からの衝突や乗物の側転（以下、ロールオーバーと称する）にも対応できるカーテン状のエアバッグが開発されている。 Conventional airbags are often mounted on the front of the driver's or passenger's seats, mainly for protecting the passenger's face and upper body during a frontal collision. Curtain-type airbags that can cope with collisions and vehicle side rolls (hereinafter referred to as rollovers) have been developed.
このカーテン状エアバッグは、車内側壁のルーフレールに沿ってフロントピラー側からリアピラー側までの領域に収納され、衝突時に側面の窓に沿って膨張、展開するように設計され、膨張可能な袋部が複数箇所で形成されるように作られている。これまでは、カーテン状エアバッグは複数枚の布を裁断し、縫製して作製されていたが、収納性に劣ることや縫製に手間が掛かるなどから、最近は、袋部外周を一重織部で閉じた袋状の高密度織物を作製してエアバッグに用いる試みがなされている。 This curtain-shaped airbag is housed in a region from the front pillar side to the rear pillar side along the roof rail on the inner side wall of the vehicle, and is designed to inflate and deploy along the side window at the time of collision. It is made to be formed at multiple locations. Until now, curtain airbags were made by cutting multiple pieces of fabric and sewing them. Recently, however, the outer circumference of the bag part has been changed to a single weaving part because it is inferior in storage and takes time and labor. Attempts have been made to produce closed bag-shaped high-density fabrics and use them in airbags.
カーテン状エアバッグに使用する高密度袋織基布は、その織密度が非常に高く、織物を製織する際には、経糸に糊剤を付着させ、経糸毛羽を防止しながら製織している。よって、高密度袋織基布を安定して製織するために、経糸に使用する糊剤種の検討などが行なわれている（例えば、特許文献１〜３参照）。 The high-density bag weave base fabric used for the curtain-shaped airbag has a very high woven density, and when weaving the woven fabric, a paste is attached to the warp to prevent warp and fluff. Therefore, in order to stably weave a high-density bag weave base fabric, examination of the type of paste used for warp has been conducted (for example, see Patent Documents 1 to 3).
経糸に糊付糸を用いた場合、糊を洗い落とす精練工程が必要であるが、高密度袋織基布の場合、袋部の中まで糸の糊を十分に落とすことは非常に困難である。糊を残せば異臭などの発生原因になる。袋状の高密度基布の糊抜きを完全に実施するには、織物をリラックスさせて揉むことや、精練槽の中にかなり長時間浸漬しておくことなどが考えられる。しかし、高密度基布を揉むとシワが発生し、そこから空気漏れが起こりやすくなることや、コート時にも均一なコート層を形成できなくなる。また、精練槽に浸漬するだけでは、糊を十分に落とすことは出来ず、精練液をゆっくりと流すなどの操作をしても、袋の中まで精練液が染み込んで糊を十分に落とすまでには、かなりの長時間を要し、とうてい工業的に実施できるものではなかった。 When a glued yarn is used for the warp, a scouring process for washing away the glue is necessary. However, in the case of a high-density bag weaving base fabric, it is very difficult to sufficiently remove the yarn glue into the bag portion. If the paste is left behind, it may cause a strange odor. In order to completely desizing the bag-shaped high-density base fabric, it is conceivable to relax the fabric and immerse it in a scouring tank or to immerse it in a scouring tank for a considerably long time. However, when the high-density base fabric is rubbed, wrinkles are generated, and air leaks from the wrinkle easily, and a uniform coating layer cannot be formed even during coating. Also, just immersing in the scouring tank will not remove the glue sufficiently, and even if the scouring liquid is poured slowly, the scouring liquid will soak into the bag until the glue is sufficiently removed. Took a considerable amount of time and was not industrially feasible.
そこで、経糸を無糊で製織することが考えられるが、無糊の経糸を用いて高密度基布を製織すると、経糸に毛羽が多発し、良好な製織が出来なかった。特に、ジャガード式開口装置を使って袋状の織物を製織する場合には、経糸密度は非常に大きなものになるため、経糸を無糊で製織するということはこれ迄不可能と考えられており、そのような製織方法に関する文献も知見も無い。 Thus, it is conceivable to weave warp without glue, but when weaving a high-density base fabric using glue-free warp, the warp frequently fuzzed, and good weaving was not possible. In particular, when weaving bag-shaped fabrics using a jacquard opening device, the warp density is very large, and it has been considered impossible to weave warp without glue. There is no literature or knowledge on such a weaving method.
無糊の経糸を用いて製織できれば、その後工程は、無精練あるいは油抜き程度の弱い精練（例えば、織物を緊張させた状態で連続的に精練槽や洗浄槽などをくぐらせる程度の精練工程）で処理できるので、基布にシワが発生することがなく、強度低下も少ない基布を得ることができる。その結果、得られた基布を用いて作製したエアバッグは、良好な機械的特性を保持することができる。また、サイジング工程で使用する糊剤やその作業にかかる製造コストを低減でき、廃糊処理が不要なので、環境にも優れた技術といえる。 If weaving can be done using glue-free warp, the subsequent process is scouring with no scouring or oil removal (for example, a scouring process in which a scouring tank or a washing tub is continuously passed while the fabric is in tension). Therefore, it is possible to obtain a base fabric which does not cause wrinkles on the base fabric and has a small decrease in strength. As a result, an airbag manufactured using the obtained base fabric can maintain good mechanical properties. In addition, the paste used in the sizing process and the manufacturing cost for the work can be reduced, and the waste paste processing is unnecessary, so it can be said to be an excellent technology for the environment.
従来、単層布（袋状に織らない布）の高密度織物に関しては、経糸に油剤やワックスを付与することや、交絡部を設けることにより、無糊で製織する方法が提案されている（例えば、特許文献４、５参照）が、経糸方向のカバーファクターが１８００以上の高密度の袋状織物に関しては、有用な技術知見は見当たらないのが現状である。
以上の通り、高密度の袋織基布を無糊で製織しようとしても、製織性が良好で、かつ高品質の基布特性を満足する製織方法は、これまで全く知られていなかった。
Conventionally, for high-density woven fabrics of single-layer fabrics (cloths that do not weave into bags), a method of weaving without glue by applying an oil agent or wax to warp yarns or by providing an entanglement portion has been proposed ( For example, see Patent Documents 4 and 5), however, there is no useful technical knowledge regarding a high-density bag-like woven fabric having a cover factor in the warp direction of 1800 or more.
As described above, no attempt has been made to date about a weaving method that has good weaving properties and satisfies high-quality base fabric characteristics even when trying to weave a high-density bag-woven base fabric without glue.
本発明の課題は、高密度袋織基布の製織において、経糸を無糊で用いても、製織性が良好で、得られる基布にはシワがなく、十分高いレベルの強度特性や内圧保持性を有する高密度袋織基布の製織方法を提供することにある。 The problem of the present invention is that, in the weaving of high-density bag woven base fabric, even if warp is used without glue, weaving is good, the resulting base fabric is free of wrinkles, sufficiently high level of strength characteristics and internal pressure retention It is another object of the present invention to provide a method for weaving a high-density bag weave base fabric.
本発明者らは、上記課題を解決するために、経糸に使用する糸の形態、交絡数、交絡強度や油付率、織機上の経糸の交絡状態、密度、あるいは経糸張力について鋭意検討を行った結果、高密度袋織基布を製織する際の糸条件、製織条件を特定範囲に設定することによって上記課題が解決できることを見出し、本発明に至った。 In order to solve the above problems, the present inventors have conducted intensive studies on the form of the yarn used for the warp, the number of entanglement, the entanglement strength and oiling rate, the entanglement state of the warp on the loom, the density, or the warp tension. As a result, the inventors have found that the above-mentioned problems can be solved by setting the yarn conditions and the weaving conditions when weaving the high-density bag weave base fabric to a specific range, and have reached the present invention.

Hereinafter, the present invention will be described in detail.
本発明の高密度袋織基布に用いられる経糸および緯糸の素材は、特に限定はなく、例えば、ナイロン６６、ナイロン６、ナイロン４６、ナイロン６１０、ナイロン６１２等の単独、またはこれらの共重合、混合により得られるポリアミド繊維、ポリエチレンテレフタレート、ポリトリメチレンテレフタレート、ポリブチレンテレフテレート、ポリエチレンナフタレートなどの単独、又はこれらの共重合、混合により得られるポリエステル繊維、パラフェニレンテレフタルアミド、およびこれと芳香族エーテルとの共重合体などに代表されるアラミド繊維、全芳香族ポリエステル繊維、ビニロン繊維、超高分子量ポリエチレン等のポリオレフィン繊維、塩化ビニル系及び塩化ビニリデン系繊維、ポリテトラフルオロエチレン系を含むフッ素系繊維、ポリサルフォン繊維、ポリフェニレンサルファイド系繊維（ＰＰＳ）、ポリエーテルケトン系繊維（ＰＥＥＫ）繊維、ポリイミド繊維、ポリエーテルイミド繊維、高強力レーヨンを含むセルロース系繊維、アクリル系繊維、炭素繊維、ガラス繊維、シリコンカーバイト繊維（Ｓｉｃ）繊維、アルミナ繊維などが用いられる。これらのうち、強度や経済的な面から合成繊維が好ましく、特に、ポリエステル繊維、ポリアミド繊維（ナイロン６、ナイロン６６）などが好ましい。 The material of the warp and weft used for the high-density bag weave base fabric of the present invention is not particularly limited. For example, nylon 66, nylon 6, nylon 46, nylon 610, nylon 612, etc. alone, or a copolymer or mixture thereof. Polyamide fiber, polyethylene terephthalate, polytrimethylene terephthalate, polybutylene terephthalate, polyethylene naphthalate, etc. obtained by the following, polyester fiber obtained by copolymerization or mixing, paraphenylene terephthalamide, and aromatics thereof Aramid fibers typified by copolymers with ethers, wholly aromatic polyester fibers, vinylon fibers, polyolefin fibers such as ultra-high molecular weight polyethylene, vinyl chloride-based and vinylidene chloride-based fibers, fluorine-based including polytetrafluoroethylene Fiber , Polysulfone fiber, polyphenylene sulfide fiber (PPS), polyether ketone fiber (PEEK) fiber, polyimide fiber, polyetherimide fiber, cellulosic fiber including high strength rayon, acrylic fiber, carbon fiber, glass fiber, silicon A carbide fiber (Sic) fiber, an alumina fiber, etc. are used. Of these, synthetic fibers are preferable from the viewpoint of strength and economy, and polyester fibers and polyamide fibers (nylon 6, nylon 66) are particularly preferable.
これらの繊維糸条には、原糸製造工程や後加工工程での工程通過性を向上させるために、各種添加剤を含有させてもよい。例えば、耐熱安定剤、耐光安定剤、老化防止剤、酸化防止剤、潤滑剤、平滑剤、顔料、撥水剤、撥油剤、酸化チタンなどの隠蔽剤、光沢付与剤、難燃剤、可塑剤、帯電防止剤、増粘剤などを一種または二種以上併用して使用することができる。また、必要に応じて、加撚、嵩高加工、捲縮加工、捲回加工などの加工を施したものを用いてもよい。 These fiber yarns may contain various additives in order to improve process passability in the raw yarn manufacturing process and the post-processing process. For example, heat stabilizer, light stabilizer, anti-aging agent, antioxidant, lubricant, smoothing agent, pigment, water repellent, oil repellent, concealing agent such as titanium oxide, gloss imparting agent, flame retardant, plasticizer, One or two or more antistatic agents and thickeners can be used in combination. Moreover, you may use what gave processes, such as twisting, a bulky process, a crimping process, and a winding process, as needed.
本発明の高密度袋織基布を構成する経糸あるいは緯糸は、各々、総繊度が１００〜５５０ｄｔｅｘであることが好ましく、より好ましくは１６０〜４７０ｄｔｅｘである。総繊度がこの範囲であれば、エアバッグの展開膨張時の衝撃に耐え得る十分な機械的強度が得られ、バースト現象が発生し難く、且つ、基布が柔軟になり、収納性が向上し、高速展開が可能となる。 The warp or weft constituting the high-density bag weave base fabric of the present invention preferably has a total fineness of 100 to 550 dtex, more preferably 160 to 470 dtex. If the total fineness is within this range, sufficient mechanical strength can be obtained to withstand the impact of the airbag when it is expanded and inflated, the burst phenomenon is unlikely to occur, the base fabric becomes flexible, and the storage property is improved. High-speed deployment is possible.
本発明の高密度袋織基布を構成する経糸の単糸繊度は、２．０〜７．０ｄｔｅｘであり、好ましくは、２．６〜３．８ｄｔｅｘである。単糸繊度が２．０ｄｔｅｘ未満であると、単糸強力が弱く、無糊での製織では毛羽の発生によって製織性が低下する。また、７．０ｄｔｅｘを越えると、単糸強力は増すが、布帛が硬くなって展開膨張時に乗員への衝撃が大きくなり、収納性にも劣る。 The single yarn fineness of the warp constituting the high-density bag weave base fabric of the present invention is 2.0 to 7.0 dtex, and preferably 2.6 to 3.8 dtex. When the single yarn fineness is less than 2.0 dtex, the single yarn strength is weak, and in weaving without glue, the weaving property decreases due to the generation of fuzz. On the other hand, if it exceeds 7.0 dtex, the single yarn strength increases, but the fabric becomes stiff and the impact on the occupant increases during expansion and expansion, resulting in poor storage.
経糸および緯糸の単糸断面の形状は、特に限定されず、丸型や三角等の異型断面等のいずれでもよいが、強度を最大限に発揮させる点からは丸断面とするのが好ましい。
本発明の高密度袋織基布を構成する織機上の経糸のカバーファクターは、１８００〜２３００であり、好ましくは１９００〜２２００である。なお、カバーファクターは次式により表される。
The shape of the single yarn cross section of the warp and the weft is not particularly limited, and may be any of a round cross section, an irregular cross section such as a triangle, and the like, but a round cross section is preferable from the viewpoint of maximizing strength.
The cover factor of the warp on the loom constituting the high-density bag weave base fabric of the present invention is 1800-2300, preferably 1900-2200. The cover factor is expressed by the following equation.
経糸のカバーファクター＝（2.54cmあたりの経糸本数）×（経糸総繊度）1/2
緯糸のカバーファクター＝（2.54cmあたりの緯糸本数）×（緯糸総繊度）1/2
例えば、織機上における経糸の２．５４ｃｍあたりの本数が１３０本であり、経糸の総繊度が２３５ｄｔｅｘの場合には、経糸のカバーファクターは１９９３となる。この経糸本数は、織機上の織り縮み後の生機での経糸密度ではなく、筬を通過する時点での経糸密度を言う。
Cover factor of warp = (Number of warps per 2.54 cm) × (Total warp fineness) 1/2
Weft cover factor = (number of wefts per 2.54 cm) x (total weft fineness) 1/2
For example, when the number of warps per 2.54 cm on the loom is 130 and the total fineness of the warp is 235 dtex, the cover factor of the warp is 1993. The number of warps refers to the warp density at the time of passing through the reed, not the warp density in the raw machine after weaving and shrinking on the loom.
また、緯糸の織機上でのカバーファクターは、１８００〜２４００であることが好ましく、より好ましくは１９００〜２２００である。よって、経糸と緯糸のカバーファクターを合わせた値は、３６００〜４７００の範囲をとる。実際のエアバッグ用袋織基布は、幾つかの処理工程を通るために収縮を起こし、経糸のカバーファクターや緯糸のカバーファクターは大きくなるが、経糸のカバーファクターの増加率の方が大きくなりがちである。 The cover factor of the weft on the loom is preferably 1800 to 2400, more preferably 1900 to 2200. Therefore, the total value of the cover factors of the warp and the weft takes a range of 3600-4700. The actual airbag woven base fabric shrinks to pass through several processing steps, and the warp cover factor and weft cover factor increase, but the increase rate of the warp cover factor tends to be larger. It is.
本発明の高密度袋織基布に用いる織物は、流体が導入されて膨張する二重袋織部の上布と下布が平組織で構成されており、該二重袋織部の外周が、並列配置された一重織部で構成された接合帯で形成されている。 The fabric used for the high-density bag weaving base fabric of the present invention is configured such that the upper and lower fabrics of the double bag weaving portion inflated by introduction of fluid are composed of a plain structure, and the outer periphery of the double bag weaving portion is arranged in parallel. It is formed of a joining band composed of a single weave portion.
本発明の高密度袋織基布に用いる経糸は、実質的に無撚の状態、即ち、撚数が０〜３００Ｔ／ｍであることが必要で、この撚数であると、基布の耐エアリーク性が良好である。撚数が３００Ｔ／ｍを超えるような場合には、糸自体に丸みが生じ、耐エアリーク性や折り畳み性などの高密度袋織基布の性能を必ずしも十分に満足しなくなることがある。 The warp used for the high-density bag-woven base fabric of the present invention needs to be substantially untwisted, that is, the twist number should be 0 to 300 T / m. Good properties. When the number of twists exceeds 300 T / m, the yarn itself may be rounded, and the performance of the high-density bag base fabric such as air leak resistance and foldability may not be sufficiently satisfied.
また、インターレース加工などによって交絡を付与することもできる。交絡数は１５〜４０個／ｍであり、好ましくは２０〜３５個／ｍの範囲である。交絡数が１５個／ｍ未満であると、製織時に経糸に毛羽が発生し、４０個／ｍを越えると、交絡処理の糸製造コストが増大する。 In addition, confounding can be provided by interlace processing or the like. The number of entanglements is 15-40 / m, preferably 20-35 / m. When the number of entanglements is less than 15 / m, fluff is generated in the warp during weaving, and when it exceeds 40 / m, the cost of entangled yarn production increases.
本発明において、交絡率は５〜７０％であり、好ましくは１５〜４０％である。交絡率が５％未満であると、製織時の綜絖や筬による擦れによって経糸が毛羽立ち、製織性が低下する。また、交絡率が７０％を越えると、交絡が強すぎるために織物表面に雨降り状の模様が目立ち、糸が丸みを帯びるために基布の耐エアリーク性が低下する。なお、交絡率とは、経糸に使用する原糸を５０ｃｍ切り取り、その原糸を水を張ったバスの上に置いたときに、交絡している長さを写真撮影などによって読み取り、全体の糸長５０ｃｍに対して交絡している長さの割合をパーセント表示したものである。 In the present invention, the confounding rate is 5 to 70%, preferably 15 to 40%. If the entanglement rate is less than 5%, the warp becomes fuzzy due to rubbing by wrinkles or wrinkles during weaving, and the weaving property is lowered. On the other hand, when the entanglement rate exceeds 70%, the entanglement is too strong, so that a rainy pattern is conspicuous on the surface of the fabric, and the yarn is rounded, so that the air leak resistance of the base fabric is lowered. The entanglement rate refers to the length of the whole yarn that is obtained by taking the length of the tangled yarn by cutting it 50cm from the yarn used for the warp and placing it on a water bath. The ratio of the length entangled with respect to 50 cm in length is displayed as a percentage.
また、織機で織られた生機から抜き出した経糸の交絡強度は、２〜４０％であることが好ましい。
交絡強度が２％未満である場合、交絡斑から、交絡の存在しない所もあるために、製織時に綜絖や筬による擦れによって、経糸が毛羽立つことがある。４０％を越える場合は、過度に交絡しているために、織物表面に雨降り状の模様が目立ったり、糸が丸味を帯びるために、内圧保持率が低下する場合がある。
Moreover, it is preferable that the entanglement strength of the warp extracted from the raw machine woven by the loom is 2 to 40%.
When the entanglement strength is less than 2%, there are places where entanglement does not exist due to entanglement spots, and thus warp may fluff due to rubbing by wrinkles or wrinkles during weaving. If it exceeds 40%, it is excessively entangled, so that a rainy pattern is conspicuous on the surface of the fabric or the yarn is rounded, so that the internal pressure retention rate may be lowered.
本発明の高密度袋織基布に用いる経糸の油剤付着量は、０．４〜３．０ｗｔ％であることが必要である。油剤付着量が０．４ｗｔ％未満の場合には、経糸と綜絖や筬とのすべりが悪くなり、経糸毛羽を生じてしまう。また、油剤付着量が３．０ｗｔ％を超える場合には、綜絖や筬に油が付着、堆積し、製織した生機に油汚れが生じることや、精練する場合には精練時間を長くする必要が生じ、残液の処理も必要で環境にも好ましくない。更に、油剤付着量が高い場合で精練を行わずにコーティングをする場合には、コート面の接着性が問題になることもある。 The oil agent adhesion amount of the warp used for the high-density bag weave base fabric of the present invention needs to be 0.4 to 3.0 wt%. When the oil agent adhesion amount is less than 0.4 wt%, the slip between the warp and the cocoon or cocoon becomes worse and warp fluff is generated. In addition, when the amount of oil agent attached exceeds 3.0 wt%, oil adheres and accumulates on the cocoons and cocoons and oil stains are produced on the weaving machine. It is also undesirable for the environment because it requires treatment of the remaining liquid. Furthermore, when coating is performed without scouring when the amount of the oil agent is high, the adhesion of the coated surface may be a problem.
この油剤付着量に関しては、原糸製造時の糸をそのまま使う場合には、原糸油剤の付着量が、そのまま経糸の油剤付着量になり、整経時にアフターオイルやアフターワックスを付与する場合には、その付着量と原糸の油剤量とを合計した量が油剤付着量となる。
本発明においては、経糸を無糊で用いる。無糊とは、アクリル系やＰＶＡ系などの糊剤を使用しないことを言うものであり、整経時に付与するアフターオイルやアフターワックスなどの範囲内であれば、付与しても差し支えない。
Regarding the amount of oil applied, if the yarn used in the production of the raw yarn is used as it is, the amount of the original yarn oil applied becomes the amount of oil applied to the warp as it is, and when after-oil or after-wax is applied during aging. The total amount of the adhesion amount and the oil amount of the raw yarn is the oil agent adhesion amount.
In the present invention, warp is used without glue. “Non-glue” means that no sizing agent such as acrylic or PVA is used, and it may be applied as long as it is within the range of after-oil or after-wax to be applied at the set time.
本発明に用いる緯糸については、経糸と同じものを使用しても良く、また、例えば、交絡が経糸よりも少ないものでも構わない。 As the weft used in the present invention, the same one as the warp may be used. For example, the weft may be less entangled than the warp.
本発明の高密度袋織基布を製織する際の経糸張力は、０．１８〜０．３２ｃＮ／ｄｔｅｘの範囲であり、０．２３〜０．２８ｃＮ／ｄｔｅｘがより好ましい範囲である。経糸張力が０．１８ｃＮ／ｄｔｅｘ未満の場合には、織前位置の前後動が大きくなり過ぎて、高密度基布に製織することが困難となる。また、経糸張力が０．３２ｃＮ／ｄｔｅｘを超える場合には、経糸に掛かる張力が高くなり過ぎて、筬や綜絖（ハーネス）との擦れによって経毛羽が生じて製織が困難となることや、精練やコーティングなどの熱処理後の収縮が大きくなり過ぎて管理しづらくなるという欠点がある。 The warp tension when weaving the high-density bag weave base fabric of the present invention is in the range of 0.18 to 0.32 cN / dtex, and more preferably in the range of 0.23 to 0.28 cN / dtex. When the warp tension is less than 0.18 cN / dtex, the back-and-forth movement at the pre-weaving position becomes too large, making it difficult to weave into a high-density base fabric. In addition, when the warp tension exceeds 0.32 cN / dtex, the tension applied to the warp becomes too high, and warp with a heel or a heel (harness) may cause warp to be difficult to weave, There is a drawback that the shrinkage after heat treatment such as coating and coating becomes too large and difficult to manage.
本発明の高密度袋織基布に用いる織物を生産する手段としては、織機はエアジェットルーム、レピアルーム、ウォータージェットルーム、プロジェクタイルルームなどを用いることができ、特に好ましくは、エアジェットルーム及びレピアルームである。ジャガード開口装置を織機上部に備えるために、水を使用しないドライ織機が好ましく、その中でも、高速化が容易なエアジェットルームやレピアルームが好ましい。 As a means for producing a woven fabric used for the high-density bag woven base fabric of the present invention, the loom can use an air jet room, a rapier room, a water jet room, a projectile room, etc., and particularly preferably in an air jet room and a rapier room. is there. In order to provide the jacquard opening device in the upper part of the loom, a dry loom that does not use water is preferable. Among them, an air jet loom and a rapier room that can easily increase the speed are preferable.
なお、高密度袋織基布は経糸密度が高いゆえに、製織時には、織前を安定させることが必要であり、全面テンプルを使用することが好ましく、この全面テンプルの円柱状のロッドには凹凸や溝を付けて、布の動きをより抑えることも織前の安定に効果がある。また、織物の両端には増糸を用いて、布のたるみを補正しても良い。さらに、高密度袋織製織においては、経糸のクロスタイミングを通常よりも早める（３００度前後）こと、イージングを積極タイプにすること、あるいは、間丁を短くするなどの方法も有効であり、これらを併用して製織してもよい。 Since the high-density bag weave base fabric has a high warp density, it is necessary to stabilize the weaving before weaving, and it is preferable to use a full-surface temple. It is also effective for the stability before weaving to suppress the movement of the fabric. Moreover, you may correct | amend the sagging of a cloth using a yarn increase at the both ends of a textile fabric. Furthermore, in high-density bag weaving, methods such as making the warp crossing timing faster (around 300 degrees), making the easing positive type, or shortening the gap are also effective. You may weave together.
次に、経糸の上げ下げを制御する機械は、ジャガード式開口装置やドビー式開口装置等を用いることができるが、電子ジャガード式開口装置が、生産性やデザイン変更に対する迅速性、デザインの精密性において有利である。ジャガードの口数は、特に制限を受けないが、２０００〜１４０００口といった口数の多い電子ジャガードの方が、複雑な形状のデザイン作成に対応できるので好ましい。 Next, the machine that controls the raising and lowering of the warp can use a jacquard opening device, a dobby opening device, etc., but the electronic jacquard opening device is more productive, quicker to change the design, and more precise in design. It is advantageous. The number of jacquard is not particularly limited, but an electronic jacquard having a large number of 2,000 to 14,000 is preferable because it can cope with design creation of a complicated shape.
本発明の高密度袋織基布を生産する場合、２００ｃｍ幅以上の織機で、ハーネスの吊り数を２本〜４本吊りとして、幅方向に２〜４個取りで高密度袋織基布を製織することが効率的である。また、デザイン変更に対応しやすくするためには、６０００口以上のジャガードに１本吊りでハーネスを吊り、任意のデザインに対応しても良い。 When producing the high-density bag weaving base fabric of the present invention, weaving the high-density bag weaving base fabric by taking 2 to 4 harnesses in the width direction with a loom having a width of 200 cm or more, with 2 to 4 harnesses suspended. Is efficient. Moreover, in order to make it easy to cope with a design change, a harness may be hung by suspending one 6,000 or more jacquards to support any design.
本発明の高密度袋織基布を生産するための織機に用いる筬は、その空間率が５０〜８０％であることが好ましく、特にエアジェットルームの場合は５０〜６５％が好ましく、レピアルームの場合には５５〜７５％がより好ましい。空間率が上記の範囲であると、筬羽間に占める経糸本数が適度であり、経糸同士の擦れ合いが少なく、筬羽に対する経糸の接触圧も小さいので毛羽立ちが起こりにくく、製織性が良好で、高品質の基布が得られ、また、筬羽の厚みが適度であるため緯糸の打込み力が安定し、特に、エアジェットルームでは緯糸が通る飛走溝内から空気が漏れる割合が小さいので、緯糸を安定して飛走させることができる。 The hull used in the loom for producing the high-density bag weave base fabric of the present invention preferably has a space ratio of 50 to 80%, particularly 50 to 65% in the case of an air jet loom, and in the case of a rapier room. Is more preferably 55 to 75%. When the space ratio is within the above range, the number of warps occupying between the wings is moderate, there is little friction between the wings, and the contact pressure of the warp against the wings is small, so that fuzzing hardly occurs and weaving is good. A high-quality base fabric is obtained, and since the thickness of the wings is moderate, the weft driving force is stable. Especially, in the air jet loom, the rate of air leakage from the flying groove through which the weft passes is small. , Wefts can fly stably.
本発明の高密度袋織基布をエアバッグとして製品化する際、空気透過性の低減、目ズレ防止、あるいはバースト防止のために、シリコーン樹脂やポリウレタン樹脂等のコート剤を高密度袋織基布の両面にコーティングすることが好ましい。コート量は薄いほうが収納性や柔軟性には優れるが、耐エアリーク性などの特性を考慮すると、２０〜１２０ｇ／ｍ２の範囲が好ましく、さらに好ましくは３０〜１００ｇ／ｍ２である。 When commercializing the high-density bag-woven base fabric of the present invention as an airbag, a coating agent such as silicone resin or polyurethane resin is added to the high-density bag-woven base fabric to reduce air permeability, prevent misalignment, or prevent burst. It is preferable to coat on both sides. The thinner the coating amount, the better the storage and flexibility, but considering characteristics such as air leak resistance, a range of 20 to 120 g / m 2 is preferable, and a range of 30 to 100 g / m 2 is more preferable.
本発明の高密度袋織基布は、コーティングの際に二重袋織部と一重織部の間にシワが発生し難いので、耐エアリーク性に優れたエアバッグを得ることができる。 Since the high-density bag weave base fabric of the present invention is unlikely to be wrinkled between the double bag weave and the single weave during coating, an air bag having excellent air leak resistance can be obtained.
本発明の製織方法によれば、経糸が無糊でも安定して製織でき、得られた基布はシワが発生し難く、強度特性や内圧保持性が十分に高いレベルで保持し得るので、高品質の高密度袋織基布を提供することができる。 According to the weaving method of the present invention, the warp can be stably woven even without glue, and the obtained base fabric is less likely to wrinkle, and the strength characteristics and internal pressure retention can be maintained at a sufficiently high level. A high-quality high-density bag weave base fabric can be provided.
