Description
本発明は、審美性に富んだ混繊糸の製造方法に関する。さらに詳細には、色の異なる繊維を混ぜる技術を高度化し、異色の繊維が単繊維の水準で均一に混繊複合した、付加価値の高い、審美性に富んだ混繊糸の製造方法に関する。 The present invention relates to a method for producing a blended yarn with high aesthetics. More specifically, the present invention relates to a method for producing a high-value-added, aesthetically rich blended yarn in which a technique for mixing fibers of different colors is advanced, and fibers of different colors are uniformly blended and mixed at the level of a single fiber.
衣料やインテリア、寝装、車両内装などに使用される繊維製品においては、色合いがその商品価値を決める重要な要素になっている。
そこで、商品価値をより高められる色合いが求められているが、繊維では、全てを同色にする以外に異色の繊維を混ぜることもでき、その分要求に広く対応できる可能性を有している（例えば、特許文献１等）。
また、異色の原着短繊維を均一に混ぜる場合は、それぞれの色の原綿の塊を紡績による混打綿工程や梳綿工程および練条工程などに通してそれらの原綿の塊を開繊したり分割したりを繰り返し行い混綿していた。
In textile products used for clothing, interiors, bedding, vehicle interiors, etc., hue is an important factor that determines the value of the product.
Therefore, there is a demand for shades that can increase the commercial value, but in the case of fibers, it is possible to mix fibers of different colors in addition to making all the same color, and there is a possibility that it can respond widely to the request accordingly ( For example, Patent Document 1).
In addition, when mixing differently colored original short fibers, the lump of raw cotton of each color is passed through a blended cotton process, spinning process and kneading process by spinning to open the lump of raw cotton. It was mixed cotton by repeating and dividing.
しかし、これらの原綿は繊維の配列がランダムな上、絡みや捲縮などで塊状を呈しており、上記のいずれの紡績工程においても、ローラーや針布あるいは櫛状物に把持され積極的に移動する繊維以外に、特にニップされることなくこれらの移動繊維に絡みや捲縮あるいは摩擦などによって引きずられながら移動する浮遊繊維塊が常に存在するなど、異色の原綿を単繊維の水準で均一に混繊することは極めて難しいことであった。 However, these raw cottons have a random fiber arrangement and are lumped due to entanglement and crimping, and are actively held by rollers, needle cloths, or combs in any of the spinning processes described above. In addition to the fibers to be woven, there is always a floating fiber mass that moves while being dragged by entanglement, crimping, friction, etc. without being niped. It was extremely difficult to be fine.
従来、異色の原着短繊維が混繊されてなる糸条は、いわゆる紡績によって混繊され製造されている。
すなわち、色相毎に別々に製造された原綿の塊が、いわゆる混打綿工程や梳綿工程および練条工程などに通され、開繊や分割を繰り返し受けて混繊されて来たわけであるが、いずれの工程においても、絡み合った原綿の大塊は細かい塊にまでは分割出来ても単繊維の水準にまで細かく分割するのはなかなか難しいことであった。
2. Description of the Related Art Conventionally, yarns obtained by mixing different colored original short fibers are mixed and manufactured by so-called spinning.
That is, the lump of raw cotton produced separately for each hue has been passed through the so-called blended cotton process, the sooting process, the kneading process, etc., and has been subjected to repeated opening and splitting to be blended. In any of the processes, the intertwined large lumps of raw cotton can be divided into fine lumps, but it is difficult to divide them finely to the level of single fibers.
しかも、異色原綿間には、繊度や捲縮特性、更には繊維長、断面形状、摩擦係数、油剤、などに違いのある場合が多く、これが原綿の塊の開繊性や分割性に影響して均一な混繊を更に難しくするため、原綿の選択にもいろいろ制約を受けるといった問題があった。
最終糸条内に残る原綿の繊維塊の繊維本数が多いと、異色のコントラストが強くなり、紡績糸の撚とあいまって霜降り状の外観が目立ったり、布帛にした場合に筋状の斑やモアレ状の斑が目立ったりして、審美性を害するケースが増加し、好ましくない。
Moreover, there are many cases where there are differences in fineness and crimping characteristics, fiber length, cross-sectional shape, friction coefficient, oil agent, etc. between different colored raw cottons, and this affects the openability and splitability of the raw cotton lump. In order to make uniform blending even more difficult, the choice of raw cotton is also subject to various restrictions.
If the number of fibers of the raw cotton lump remaining in the final yarn is large, the contrast of the different colors becomes strong, and when it is combined with the twist of the spun yarn, a marbling appearance is noticeable, and when it is made into a fabric, streaks and moire are observed. The number of cases in which the shape of the spots is noticeable and harms aesthetics increases, which is not preferable.
この残留繊維塊の繊維本数を少なくする方法としては、これまで異色原綿間の物性差を少なくしたり、上記の混打綿工程、梳綿工程、練条工程に幾度も通したりするしか無く、異色の原着短繊維が単繊維の水準で均一に混繊された、審美性に富んだ色合いを有した糸条を得るには、上記煩雑な手間を掛けるだけに止まらず、上記方法を上手に使いこなす熟練した技術が必要であった。
この他にも、原綿の色を変えるたびに全ての紡績工程を徹底的に掃除する必要があり、ロット間で色合い差が生じ易いなど、生産管理の面でも困難を有していた。
As a method of reducing the number of fibers of this residual fiber lump, there is no choice but to reduce the difference in physical properties between different colored raw cotton so far, or to pass through the above-mentioned mixed cotton process, carding process, and kneading process several times, In order to obtain a yarn having an aesthetic hue, in which different colored original short fibers are uniformly mixed at the level of a single fiber, the above method is not limited to the above troublesome work. It was necessary to have skilled skills.
In addition to this, every time the raw cotton color is changed, it is necessary to thoroughly clean all the spinning processes, and there is a difficulty in production management such as a difference in color between lots.
本発明は、上記背景技術に鑑みなされたもので、その目的は、異色の原着繊維が単繊維の水準で均一に混繊され、紡績糸の風合いを呈し、従来に無い優れた色合いを有する審美性に富んだ混繊糸の製造方法を提供することにある。 The present invention has been made in view of the above-mentioned background art, and its purpose is to uniformly mix original fibers of different colors at the level of a single fiber, exhibit a texture of spun yarn, and have an excellent color that has not existed in the past. An object of the present invention is to provide a method for producing a blended yarn with high aesthetics.
本発明者が鋭意検討した結果、かかる課題は次の方法によって解決できることを見出した。
すなわち、本発明は、色の異なる複数本の原着長繊維束をそれぞれ扁平に開繊して扁平糸条とし、それらを扁平の厚み方向に重ね合わせて、これを周速度の異なる２組のニップローラーを、低速のニップローラー、高速のニップローラーの順で通過させ、その際、いずれのニップローラーにおいても該扁平の状態を維持するように、該扁平糸条を厚み方向に挟んで把持し、かつ該２組のニップローラー間で該扁平糸条を牽切し、その後、空気噴射ノズルに通して抱合することを特徴とする審美性に富んだ混繊糸の製造方法が提供される。
As a result of intensive studies by the present inventors, it has been found that such a problem can be solved by the following method.
That is, in the present invention, a plurality of original long fiber bundles having different colors are flattened into flat yarns, which are superposed in the thickness direction of the flats, and these are set in two sets having different peripheral speeds. Pass the nip roller through the low-speed nip roller and then the high-speed nip roller in this order, holding the flat yarn in the thickness direction so that the flat state is maintained in any nip roller. In addition, a method for producing a blended yarn with high aesthetics is provided, in which the flat yarn is checked between the two sets of nip rollers, and then knitted through an air jet nozzle.
本発明によれば、異色の原着繊維が単繊維の水準で均一に混繊されてなる、従来に無い審美性に富んだ混繊糸が得られる。また、本発明では、一工程で生産が可能なため、色合いを変える場合も、多工程からなる従来の紡績に比べ、はるかに少ない手間で済むなどの利点がある。 According to the present invention, an unprecedented blended yarn with high aesthetics can be obtained, in which different colored primary fibers are uniformly blended at the level of a single fiber. Further, in the present invention, since the production can be performed in one process, there is an advantage that even when changing the hue, much less labor is required compared to the conventional spinning composed of multiple processes.
本発明は、複数本の色の異なる原着長繊維束を用いて、審美性に富んだ混繊糸の製造方法である。上記の複数本の原着長繊維束を構成する素材としては、ポリエチレンテレフタレート、ポリエチレンナフタレート、ポリブチレンテレフタレート、ポリトリチレンテレフタレート等のポリエステル、ナイロン６、ナイロン６６等の脂肪族ポリアミドや、芳香族ポリアミド、ポリエチレン、ポリプロピレン等のポリオレフィンを例示することができる。複数本の色の異なる原着長繊維束は、それぞれ素材が異なっていてもよい。 The present invention is a method for producing a blended yarn having high aesthetics by using a plurality of original long fiber bundles having different colors. As a material constituting the above-mentioned plurality of original fiber bundles, polyethylene terephthalate, polyethylene naphthalate, polybutylene terephthalate, polytriethylene terephthalate and other polyesters, nylon 6, nylon 66 and other aliphatic polyamides, and aromatics Examples thereof include polyolefins such as polyamide, polyethylene, and polypropylene. The raw fiber bundles of different colors may have different materials.
また、上記本発明の原着長繊維束として同種のポリマーを用いた場合は、製織後に精錬や熱セットを行っても、繊維間で収縮差や摩擦係数差がないため分離しにくく、均一な混繊糸が得られる。同種のポリマーからなる繊維を用いる場合は、物性や取り扱い性の点で、ポリエステルが好ましい。 In addition, when the same kind of polymer is used as the original long fiber bundle of the present invention, even if refining or heat setting is performed after weaving, there is no difference in shrinkage or friction coefficient between fibers, so separation is difficult and uniform. A blended yarn is obtained. When using the fiber which consists of the same kind of polymer, polyester is preferable at the point of a physical property or a handleability.
上記の原着長繊維束を構成する原着長繊維には、例えば、フタロシンアン系顔料、アゾ系顔料等染料等が公知の顔料が含まれているものを採用することができる。また、上記の原着長繊維には、該長繊維の重量を基準として、顔料が０．０５〜５重量％程度練り込まれていれているものを用いることができる。 As the original long fibers constituting the above-mentioned original long fiber bundle, for example, a dye containing a known pigment such as a phthalosin pigment or an azo pigment can be used. In addition, as the above-mentioned original long fibers, those in which a pigment is kneaded by about 0.05 to 5% by weight based on the weight of the long fibers can be used.
本発明に用いるそれぞれ原着長繊維束の総繊度としては、好ましくは１００〜１００００ｄｔｅｘであり、より好ましくは５００〜５０００ｄｔｅｘであり、単繊維繊度としては、好ましくは０．１〜２０ｄｔｅｘであり、より好ましくは０．５〜１０ｄｔｅｘである。また、各原着長繊維束の総繊度、単繊維繊維は同じであっても異なっていてもよい。 The total fineness of each original long fiber bundle used in the present invention is preferably 100 to 10,000 dtex, more preferably 500 to 5000 dtex, and the single fiber fineness is preferably 0.1 to 20 dtex, and more Preferably it is 0.5-10 dtex. In addition, the total fineness and single fiber of each original long fiber bundle may be the same or different.
本発明は、色の異なる複数本の原着長繊維束をそれぞれ扁平に開繊して扁平糸条とし、それらを扁平の厚み方向に重ね合わせて、これを周速度の異なる２組のニップローラーを、低速のニップローラー、高速のニップローラーの順で通過させ、その際、いずれのニップローラーにおいても該扁平の状態を維持するように、該扁平糸条を厚み方向に挟んで把持し、かつ該２組のニップローラー間で該扁平糸条を牽切し、その後、空気噴射ノズルに通して抱合することを特徴とする審美性に富んだ混繊糸の製造方法である。かかる方法によって、異色の原着繊維が単繊維の水準で均一に混繊され、従来に無い審美性に富んだ色合いを有した混繊糸が初めて得られる。 In the present invention, a plurality of original long fiber bundles of different colors are flattened to form flat yarns, which are superposed in the thickness direction of the flats, and these are two sets of nip rollers having different peripheral speeds Are passed in the order of a low-speed nip roller and a high-speed nip roller, and at that time, the flat yarn is sandwiched in the thickness direction so as to maintain the flat state in any nip roller, and The flat yarn is checked between the two sets of nip rollers, and then knitted through an air jet nozzle. By such a method, different colored primary fibers are uniformly mixed at the level of a single fiber, and for the first time, a mixed yarn having an unprecedented aesthetically rich hue can be obtained.
すなわち、扁平に開繊し、繊維が平行に配列している色の異なる複数本の原着長繊維束を、扁平の厚み方向に重ね合わせ、扁平の状態を維持するよう、扁平の厚み方向に一対の低速のニップローラーで把持することにより、それぞれの繊維が大きな塊状になることなく１本１本の繊維がばらばらに混ざり合った繊維束が得られる。 That is, in order to maintain a flat state by superimposing a plurality of differently attached original long fiber bundles that are spread flat and fibers are arranged in parallel in the flat thickness direction, By gripping with a pair of low-speed nip rollers, a fiber bundle in which the individual fibers are mixed apart can be obtained without each fiber becoming a large lump.
また、高速のニップローラーでも、低速のニップローラーから送り出されてくる色の異なる長繊維からなる扁平糸条を、扁平の状態を維持するよう、扁平の厚み方向に把持すると共に、両ニップローラー間で、上記扁平糸条を牽切する。この際、高速のニップローラーと低速にニップローラーの周速度比に対応して、扁平糸条中に残留しているそれぞれの色の小繊維塊が減少する。 In addition, even with a high-speed nip roller, a flat yarn made of long fibers of different colors fed from a low-speed nip roller is gripped in the thickness direction of the flat so as to maintain the flat state, and between the nip rollers. Then, the flat yarn is checked. At this time, the small-fiber lumps of the respective colors remaining in the flat yarn are reduced corresponding to the peripheral speed ratio of the high-speed nip roller and the low-speed nip roller.
さらに、低速のニップローラーから送り出される扁平糸条は、高速のニップローラーに届いた順に繊維が１本ずつ把持され牽切されるので、それぞれの繊維が単繊維の水準で混ざりあった混繊状態が得られる。 Furthermore, the flat yarn fed from the low-speed nip roller is held and checked one by one in the order of arrival at the high-speed nip roller, so that each fiber is mixed at the single fiber level. Is obtained.
本発明では、上記工程の後、高速のニップローラーから送出される繊維束を空気噴射ノズルに通して抱合するが、その際にも、空気噴射ノズルによって１本１本の繊維が撹乱され、より細かい混繊状態が得られる。 In the present invention, after the above process, the fiber bundle sent from the high-speed nip roller is entrapped through the air injection nozzle, and even in this case, each fiber is disturbed by the air injection nozzle, and more A fine mixed state can be obtained.
次に、図を用いて本発明の一実施形態について詳細に説明する。図１（１）は本発明を実施するための装置の一例を示す概略図、図１（２）は図１（１）において、ガイドＧ３通過後、原着長繊維束Ａ、Ｂを開繊した各扁平糸条を重ね合わせてニップローラーＲ１に供給する部分の斜視図を示す概略図である。 Next, an embodiment of the present invention will be described in detail with reference to the drawings. FIG. 1 (1) is a schematic view showing an example of an apparatus for carrying out the present invention, and FIG. 1 (2) is a drawing of the original long fiber bundles A and B after passing through the guide G3 in FIG. 1 (1). It is the schematic which shows the perspective view of the part which piles up each made flat yarn and supplies it to nip roller R1.
すなわち、図１において、色の異なる原着長繊維束ＡおよびＢをそれぞれ開繊ガイドＧ１およびＧ２に通して屈曲を与えながら扁平に薄く開繊し、次いでこれらを厚み方向に重ね合わせた後、開繊した扁平糸条を低速のニップローラーＲ１およびこれより周速度が速い高速のニップローラーＲ２に通し、その際、両ニップローラーでは扁平の状態を維持するように該扁平糸条を厚み方向に挟んで把持し、さらに両ニップローラー間で原着長繊維束ＡおよびＢからなる扁平糸条を牽切し、次いでニップローラーＲ２とニップローラーＲ３の間の空気噴出ノズルＮ１を用いて牽切した繊維束を吸引し、さらに空気噴出ノズルＮ２を用いて該繊維束を抱合し、オイリング装置Ｏにより繊維油剤を施してワインダーＷに巻き取り、本発明の混繊糸を製造することができる。 That is, in FIG. 1, the original long fiber bundles A and B having different colors are opened thinly flatly while passing through the opening guides G1 and G2, respectively, and then overlapped in the thickness direction. The opened flat yarn is passed through the low-speed nip roller R1 and the high-speed nip roller R2 having a higher peripheral speed. At this time, the flat yarn is moved in the thickness direction so that both nip rollers maintain a flat state. The flat yarn composed of the bundled long fiber bundles A and B was checked between both nip rollers, and then checked using the air ejection nozzle N1 between the nip rollers R2 and the nip rollers R3. The fiber bundle is sucked, and the fiber bundle is conjugated using the air ejection nozzle N2, and the fiber oil agent is applied by the oiling device O and wound around the winder W to produce the mixed yarn of the present invention. It can be.
原着長繊維束の製造方法としては、顔料を混練りしたベースポリマー系の原着マスターチップをベースポリマーチップに添加して溶融紡糸するなど公知の方法を採用することができる。 As a method for producing the original long fiber bundle, a known method such as adding a base polymer-based original master chip kneaded with a pigment to the base polymer chip and performing melt spinning can be employed.
ニップローラーＲ１とニップローラーＲ２間での牽切を容易にするためには、ニップローラーＲ１に供給される糸条に、撚りや交絡が付与されていないことが好ましい。また、該糸条には、繊維油剤が付与されていてもよいが収束性や摩擦が少なくかつ静電気の起こり難い油剤が好ましい。すなわち、撚りや交絡や静電気あるいは繊維油剤の収束性や摩擦などが高いと、牽切斑が生じ易くなるため好ましくない。 In order to facilitate checking between the nip roller R1 and the nip roller R2, it is preferable that the yarn supplied to the nip roller R1 is not twisted or entangled. Moreover, although the fiber oil agent may be provided to this yarn, the oil agent with little convergence property and friction and being hard to generate static electricity is preferable. That is, twisting, entanglement, static electricity, fiber oil agent convergence, friction, and the like are not preferable because check spots are likely to occur.
また、開繊ガイドＧ１、Ｇ２としては、公知の円筒形あるいは中央部が膨らんだ紡錘形の棒状ガイドを数本平行に並べたもの、あるいは棒状ガイドを円弧状に曲げたガイドを数本並べたものが使用できる。開繊ガイドは、セラミック製、金属製等のものを任意に採用することができる。 Further, as the opening guides G1 and G2, a plurality of known cylindrical or spindle-shaped rod-shaped guides in which the central portion is expanded are arranged in parallel, or a plurality of guides obtained by bending the rod-shaped guide into an arc shape are arranged. Can be used. As the opening guide, ceramic, metal or the like can be arbitrarily adopted.
なお、上記開繊ガイド後方のニップローラーＲ１の直前部での開繊した扁平糸条の幅を若干規制し縮小するガイドＧ３を設けてやると、扁平糸条端部の繊維密集度が増してニップローラーＲ１への繊維巻き付を防止でき、好ましい。 In addition, if the guide G3 which restricts and reduces the width | variety of the opened flat yarn in the part just before the nip roller R1 behind the said opening guide is provided, the fiber density of a flat yarn end part will increase. The fiber wrapping around the nip roller R1 can be prevented, which is preferable.
また、ニップローラーＲ１の周速度：ニップローラーＲ２の周速度の比は１：８〜１：４０が好ましく、１：１０〜１：３０がより好ましい。すなわち、上記周速度の比が、１：８未満になると、ニップローラーＲ１の周速度を速める必要が生じるため牽切後の繊維端がこれに巻き付き易くなり、一方１：４０を超えると牽切斑などによる牽切糸条の太細比が大きくなり、好ましくない。 The ratio of the peripheral speed of the nip roller R1 to the peripheral speed of the nip roller R2 is preferably 1: 8 to 1:40, and more preferably 1:10 to 1:30. That is, when the ratio of the peripheral speeds is less than 1: 8, it is necessary to increase the peripheral speed of the nip roller R1, so that the fiber end after the checkout is easily wound around the ratio. The thickness ratio of the check yarn due to spots increases, which is not preferable.
また、ニップローラーＲ２の牽切域側には、該ローラー表面に発生する空気の随伴流がニップ点においてローラー端部方向に流れるのを遮断するガイドＧ４を設けることが好ましい。すなわち、該随伴流を遮断しないと、ニップローラーＲ１から送り出されてくる繊維の先端がニップローラーＲ２に安定してニップするのが難しくなる傾向があり、このため牽切斑が生じ易くなり、好ましくない。 Moreover, it is preferable to provide the guide G4 which interrupts | blocks the accompanying flow of the air which generate | occur | produces on this roller surface in the nip roller R2 flow toward a roller edge part direction at a nip point. That is, if the accompanying flow is not interrupted, it tends to be difficult for the tip of the fiber fed from the nip roller R1 to stably nip the nip roller R2. Absent.
また、空気噴射ノズルＮ１としては、ニップローラーＲ２から搬出されてくる牽切繊維が該ローラーに捲き付かないように吸引作用を有したノズルが使用されるが、吸引作用と同時に旋回作用を有したノズルを使用すると、繊維をより有効に吸引でき好ましい。 Further, as the air injection nozzle N1, a nozzle having a suction action is used so that the check fiber carried out from the nip roller R2 does not stick to the roller, but it has a turning action simultaneously with the suction action. Use of a nozzle is preferable because fibers can be sucked more effectively.
一方、空気噴出ノズルＮ２としては、目的に応じて、牽切された繊維束に旋廻流によって繊維端を巻き付けて結束抱合するもの、あるいは牽切された繊維束内の繊維同士を撹***絡させて抱合するものが使用できる。 On the other hand, as the air ejection nozzle N2, depending on the purpose, the fiber end is wound around the checked fiber bundle by a swirl flow and bound and conjugated, or the fibers in the checked fiber bundle are disturbed and entangled. Conjugates can be used.
また、オイリング装置Ｏとしては、オイリングローラー方式やオイリングガイド方式の装置が使用でき、油剤も目的に応じて選定できる。 Further, as the oiling device O, an oiling roller type or an oiling guide type device can be used, and an oil agent can also be selected according to the purpose.
以上に説明した製造方法によって、色の異なる複数本の原着繊維からなる混繊糸であって、該原着繊維がいずれも原着長繊維束を牽切した繊維からなり、該混繊糸の断面において同じ色を有する単繊維が５本以上の繊維束として存在していない審美性に富んだ混繊糸を得ることがでできる。 According to the production method described above, a mixed yarn composed of a plurality of original fibers having different colors, each of the original fibers is formed by checking a bundle of original long fibers, and the mixed yarn It is possible to obtain a blended yarn with high aesthetics, in which no single fiber having the same color in the cross section is present as a bundle of five or more fibers.
上記混繊糸を構成する単繊維の平均繊維長としては、５〜１５０ｃｍが好ましく、１０〜３０ｃｍがより好ましく、１０〜２５ｃｍがさらに好ましい。平均繊維長が５ｃｍ未満では風綿が生じやすく牽切糸の成形が難しくなる傾向があり、１５０ｃｍを超えると審美性が悪くなり、スパンライクな風合いが得られない傾向がある。 As an average fiber length of the single fiber which comprises the said mixed fiber, 5-150 cm is preferable, 10-30 cm is more preferable, 10-25 cm is further more preferable. If the average fiber length is less than 5 cm, fluff is likely to occur, and it is difficult to form a check yarn. If it exceeds 150 cm, the aesthetics are deteriorated and a spun-like texture tends to be not obtained.
