本発明はボリエステル繊維の高速製糸方法に関する。 さらに詳し く述べるならば、 本発明は 3000 m Z分以上の高速でも工程安定性が 良好で、 且つ高品位のボリエステル織維が得られる高速製糸方法に 閩するものである。 背景技術  The present invention relates to a high-speed spinning method for polyester fibers. More specifically, the present invention is directed to a high-speed spinning method capable of obtaining a high-quality polyester fiber having good process stability even at a high speed of 3000 mZ or more. Background art
近年における合成繊維の製糸技術の進歩はめざましく、 殊に高速 ワイ ンダ一の開発に伴い、 その製糸速度は益々増大の方向に向かつ ている。 これらの高速製糸技術は、 吐出生産性の向上と、 その製品 がその紡糸過程で発生する特有の織維微細構造の変化から生ずる特 異な特性を有し、 従って、 この特性を利用する新たなる用途展開に ついて、 各種の研究開発が推し進められている。  In recent years, the synthetic fiber spinning technology has made remarkable progress, particularly with the development of high-speed winders, and the spinning speed has been increasing. These high-speed spinning technologies have special properties resulting from the improvement of discharge productivity and the characteristic changes in the microstructure of the textile that occur during the spinning process, and therefore new applications utilizing this property Various R & D activities are being promoted.
しかしながら、 製糸速度の増大に伴い、 走行糸条と各種糸導 （口 一ラー、 ガイ ド等） との擦通、 及び走行糸束間内での織維同士の擦 過が増大し、 単糸切れ、 および、 それに起因する糸切れが発生し、 得られた糸の品位をそこなうばかりでなく、 かえって生産効率を低 下せしめることにもなるという問題を舎んでいる。  However, as the yarn production speed increases, the rubbing between the running yarn and various yarn guides (such as a stirrer and a guide) and the rubbing of the fibers between the running yarn bundles increase, and the single yarn There is a problem that breakage and the resulting yarn breakage not only impair the quality of the obtained yarn, but also reduce the production efficiency.
これらの問題解消のためには、 紡出糸条への耠油用油剤や耠油方 法に閬する提案、 並びに、 走行糸条の集束性向上のための糸束への 空気処理に閬する提案等についていろいろとなされてきている。 し かし、 給油用油剤そのものに関する提案については、 いずれをもつ てしても未だ不適切か不充分なものであり、 上記問題点を高度に解 決するものは見出されていないのが現状である。 発明の開示 In order to solve these problems, the proposals should be made on oiling agents and oiling methods for spun yarns, and air treatment of yarn bundles to improve the convergence of running yarns.

本発明者らは、 上記目的を達成するべく鋭意検討した結果、 高速 度で製糸する際には、 特定の油剤組成物からなる処理油剤ェマルジ ョ ンを付与することが極めて重要であることを見出し、 本発明を完 成した。  As a result of intensive studies to achieve the above object, the present inventors have found that it is extremely important to provide a treated oil agent emulsion comprising a specific oil agent composition when spinning at a high speed. Thus, the present invention has been completed.
即ち、 本発明に係るポリエステルの高速製糸方法は、 3000 m Z分 以上の紡糸速度でポリエステル織維を高速製糸する方法において、 前記ボリ エステル緻維に、 平均分子量が 300 〜500 の一塩基酸エス テルを主体成分として舍み、 更に、 下記成分 （ a ) 及び （ b ) ： That is, the high-speed spinning method for polyester according to the present invention is a method for high-speed spinning of polyester fiber at a spinning speed of 3000 mZ or more, wherein the polyester fiber has a monobasic acid ester having an average molecular weight of 300 to 500.

本発明方法は、 主たる操り返し単位がアルキレンテレフタ レート であるボリエステル、 例えばポリ エチレンテレフタレー トからなる 織維を主たる対象とし、 紡糸速度が SOOO m Z分以上で溶融紡糸され る織維、 好ましく は 3500〜4000 m Z分の速度で引き取られ、 次いで 延伸される繊維に適用される。 The method of the present invention is mainly directed to a fiber whose main repeating unit is an alkylene terephthalate, for example, a fiber composed of polyethylene terephthalate, and a fiber spun at a spinning speed of at least SOOO mZ, preferably a fiber. Is picked up at a speed of 3500-4000 mZ, then Applies to fibers to be drawn.
紡糸速度が SOOO m Z分未満の場合には、 従来汎用されている給油 用油剤を用いても前述の工程調子あるいは品質上の問題は発生しな いので、 本発明方法を適用する必要がない。 本発明にかかる油剤は、 3000 m Z分以上の紡糸速度で製糸する際に初めて効果を発現するも のである。  When the spinning speed is less than SOOO mZ minutes, there is no need to apply the method of the present invention because the above-described process condition or quality problem does not occur even if a conventional oiling agent is widely used. . The oil agent according to the present invention exhibits an effect only when spinning at a spinning speed of 3000 mZ or more.
本発明においては、 高速紡糸されたポリ エステル繊維には、 高速 で走行する糸条に抵抗な く付着せしめるために、 油剤を、 水で希釈 された水系ェマルジヨ ンとして、 ボリ エステル繊維に付与する必要 がある。 いわゆる水を含まないス ト レー ト型油剤では、 その粘度が 高く、 走行糸条への濡れが悪くなつて、 得られるボリ エステル繊維 糸条に毛羽が発生し易くなったり、 ォイ リ ング時走行糸条に負荷が かかりすぎて単織維切れが発生し易くなつたりするので好ましくな い。  In the present invention, in order to adhere the high-speed spun polyester fibers to the yarn running at high speed without resistance, it is necessary to apply an oil agent to the polyester fibers as an aqueous emulsion diluted with water. There is. In the case of a so-called water-free straight type oil, the viscosity is high and the wetness of the running yarn becomes poor, so that the resulting polyester fiber yarn is liable to generate fluff or to be liable to be oiled. It is not preferable because the load on the running yarn is excessively applied and the single-weave is easily broken.
本発明において、 油剤の主体成分として用いられる一塩基酸エス テル化合物は、 油剤の有効成分全重量に対して 5 0重量％以上、 好 ま しく は 5 0〜 7 5重量％の含有率で油剤中に舍まれることが必要 であり、 それが 5 0重量％未満の場合には、 得られる油剤は、 3000 mノ分以上の高速紡糸に要求される潤滑性を付与することができな く なり、 得られるポリエステル繊維糸条における毛羽及び糸切れの 発生が増大するため好ましくない。  In the present invention, the monobasic acid ester compound used as a main component of the oil agent has a content of 50% by weight or more, preferably 50 to 75% by weight, based on the total weight of the active ingredient of the oil agent. If it is less than 50% by weight, the resulting oil cannot provide the lubricity required for high-speed spinning of 3000 m / min or more. It is not preferable because fluff and yarn breakage in the obtained polyester fiber yarn increase.
本発明に用いられる一塩基酸エステルは、 一価の脂肪族カルボン 酸と一価の脂肪族アルコールとから得られるモノ エステル化合物で あって、 その分子量は 300 〜500 、 好まし く は 350 〜450 である。 このような一塩基酸エステルは、 具体的には、 ォクチルパルミテー ト、 ォクチルステア レー ト、 ラウ リ ルラウ レー ト、 2 —ェチルへキ シルステアレー ト、 イ ソ ト リ デシルパルミテー ト、 イ ソステアリ ル カプリ レー ト等から選ばれることが好ましい。 The monobasic acid ester used in the present invention is a monoester compound obtained from a monohydric aliphatic carboxylic acid and a monohydric aliphatic alcohol, and has a molecular weight of 300 to 500, preferably 350 to 450. It is. Specific examples of such monobasic acid esters include octyl palmitate, octyl stearate, lauryl laurate, 2-ethylhexyl stearate, isotridecyl palmitate, and isostearyl. It is preferably selected from caprylate and the like.
分子量が 500 を越える一塩基酸エステル、 または二価以上の多塩 基酸エステルを用いた場合には、 製糸時の走行糸と糸案内部材との 摩擦が増大して、 得られるボリ エステル繊維糸条に毛羽、 糸切れが 発生することになり好ましく ない。 また分子量が 300 未満の一塩基 酸エステルを用いると、 製糸に続いて行われる延伸又は熱処理のェ 程において、 加熱により発煙を生じ易く、 作業環境汚染の問題を引 き起こすため好ましくない。  When a monobasic acid ester having a molecular weight of more than 500 or a polybasic acid ester having a valency of 2 or more is used, the friction between the running yarn and the yarn guide member at the time of yarn production increases, and the resulting polyester fiber yarn is obtained. It is not preferable because fluffs and thread breaks occur in the strip. It is not preferable to use a monobasic acid ester having a molecular weight of less than 300, because in the drawing or heat treatment performed subsequent to the spinning, fumes are easily generated by heating, which causes a problem of working environment pollution.
本発明で用いられる油剤において、 もう一つの必須成分 （ a ) と して用いられるポリォキシアルキレンダリ コール共重合体は、 ポリ エステル繊維周面上に形成される油剤膜の強度を高め、 糸に耐摩耗 性、 酎擦通性を付与するものである。 これらの特性向上の効果によ り、 高速製糸遏程中の糸と糸案内部材、 あるいは糸同士の耐摩耗性 に有効に働き、 毛羽が極めて少ない糸が、 断糸することなく効率よ く製糸できるといったことが見い出されたのである。 かかる油膜強 度向上により糸の »摩耗性を向上するために、 従来より硬化ヒマシ 油の高重合物、 多価アルコ一ルのボ リ エステル等を添加する方法が 提案されているが、 これらの方法ではある程度の効果は得られるも のの、 高速製糸で要求される程度の効果を得るためには、 それを多 量に用いることが必要になる。 このため、 繊維簡摩擦が通度に低下 し、 高速で捲き取る原糸のパッケージの捲姿が不安定なものとなり、 操業性の低下や後加工工程における原糸の解舒性不良等の問題が引 き起こされる。  In the oil agent used in the present invention, the polyoxyalkylene dalicol copolymer used as another essential component (a) increases the strength of the oil agent film formed on the peripheral surface of the polyester fiber, It imparts abrasion resistance and shochu rubbing property to the surface. The effect of improving these properties effectively works on the abrasion resistance between the yarn and the yarn guide member during the high-speed yarn production process, or between the yarns, and the yarn with extremely little fuzz is efficiently produced without breaking the yarn. It was found that they could do it. In order to improve the abrasion resistance of the yarn by improving the oil film strength, a method of adding a high polymer of hardened castor oil or a polyhydric alcohol polyester has been proposed. Although the method can provide a certain degree of effect, it is necessary to use a large amount of it in order to obtain the effect required for high-speed spinning. As a result, the simple friction of the fiber is reduced, and the winding form of the raw yarn wound at high speed becomes unstable, resulting in problems such as reduced operability and poor unwinding property of the raw yarn in the post-processing step. Is caused.
本発明者らは、 上記の問題について鋭意研究した結果、 パッケ一 ジの捲姿は、 比較的低荷重下でうける繊維簡静摩擦の値に依存する ものであり、 一方高速製糸時に、 ポリ エステル織維がうける摩擦応 力の大きさは、 高温、 高荷重下における繊維藺静摩擦の値により変 化することを見い出した。 そして後者の静摩擦の低減効果が大き く 、 且つ前者の静摩擦はあまり低減させない油剤成分について検討した 結果、 特定の分子量を有するポリオキシアルキ レ ングリ コール共重 合体を特定量配合することが有効であることを見い出したのである。 The present inventors have conducted intensive studies on the above-mentioned problems, and as a result, the winding shape of the package depends on the value of the fiber static friction under a relatively low load. The magnitude of the frictional stress applied depends on the value of the fiber rub static friction at high temperature and high load. Has been found. After examining the oil component which has a large effect of reducing the static friction of the latter and does not significantly reduce the static friction of the former, it is effective to mix a specific amount of a polyoxyalkylene glycol copolymer having a specific molecular weight. I found something.
すなわち、 本発明で用いられる油剤の必須成分 （ a ) は、 平均分 子量が 1000以上のボリオキシアルキ レ ングリ コール共重合体であり、 この成分 （ a ) は油剤の有効成分全重量に対して 1〜 1 5重量％の 舍有量で含まれる必要がある。 その含有量が 1重量％未満の場合に は、 油膜強度向上の効果は不充分であり、 一方それが 1 5重量％を 越える場合には、 油剤の粘度増加により走行糸条の動摩擦係数が増 大して毛羽が発生し易く なり、 静摩擦係数は逆に低下してパッケ一 ジの捲姿が悪化し易くなるので好ましくない。 また、 成分 （ a ) を 過度に大量に用いると、 後加工工程としての糊付工程において、 糊 皮膜を軟化せしめて糊付効果を低滅したり、 糊落ちを引き起こして 製織効率を低下せしめるといった問韪を生ずる。 また平均分子量が 1000未滴の場合には、 得られる油剤の凝集力が不充分になり、 また 油膜強度向上効果も不充分となるため本発明の目的を達成すること が不可能になる。  That is, the essential component (a) of the oil agent used in the present invention is a boroxyalkylene glycol copolymer having an average molecular weight of 1000 or more, and this component (a) is based on the total weight of the active ingredient of the oil agent. It should be contained in a total amount of 1 to 15% by weight. If the content is less than 1% by weight, the effect of improving the oil film strength is insufficient, while if it exceeds 15% by weight, the dynamic friction coefficient of the running yarn increases due to an increase in the viscosity of the oil agent. It is not preferable because fluff is likely to occur, and the coefficient of static friction is reduced to the contrary, and the appearance of the package is easily deteriorated. Also, if the component (a) is used in an excessively large amount, in the sizing step as a post-processing step, there is a problem that the sizing film is softened to reduce the sizing effect, or that the wetting efficiency is reduced due to sizing. Produces 韪. When the average molecular weight is not less than 1,000, the cohesive force of the obtained oil agent is insufficient and the effect of improving the oil film strength is also insufficient, so that the object of the present invention cannot be achieved.
本発明に用いられるポリオキシアルキレングリ コール共重合体と しては、 例えば倒鎮としてアルキル基を有するエチレンォキサイ ド /プロピレンォヰサイ ド共重合体、 側鎖を有していないエチレンォ キサイ ド テ トラヒ ドロフラ ン共重合体 （エチレンォキシ単位 · テ トラメチレンォキシ単位からなる共重合体） 等をあげることができ、 これらの末端水酸基は、 アルキル基、 ァリール基、 ァ シル基等で封 鎖されていてもよ く、 また未封鎖のままでもよい。 これらのなかで エチ レ ンォキサイ ド Zプロ ピ レ ンォキサイ ド共重合体を用いる場合 には、 平均分子量が 9000以上のもの、 特に共重合比が 2 0ノ 8 0〜 8 0 / 2 0 ( E0ZP0重量比） の共重合体で分子量が 9000〜30000 の ものを 4〜 1 5重量％用いることが望ましい。 またエチレンォキサ イ ド Ζテ トラヒ ドロフラン共重合体を用いる場合には、 これらモノ マーの兵重合比が 2 0 / 8 0〜 8 0 / 2 0 (重量比） であり、 かつ 平均分子量が 1000〜7000のものを 1 〜 1 0重量％、 特に 1〜 5重量 %用いることが望ましい。 なかでも側鎮を有していないエチレンォ キサイ ド Ζテ トラヒ ドロフラン共重合体を用いる場合には、 油膜強 度向上の効果が大き く、 このため高速製糸時におけるボリエステル 繊維糸条の毛羽発生および断糸に対する抑制効果が極めて大き く好 ましい。 Examples of the polyoxyalkylene glycol copolymer used in the present invention include an ethylene oxide / propylene oxide copolymer having an alkyl group as a countermeasure, and an ethylene oxide having no side chain. Examples thereof include tetrahydrofuran copolymers (copolymers composed of ethyleneoxy units and tetramethyleneoxy units). These terminal hydroxyl groups are blocked with an alkyl group, aryl group, or acyl group. And may be left unblocked. Among these, when an ethylene oxide Z propylene oxide copolymer is used, the copolymer having an average molecular weight of 9000 or more, especially a copolymerization ratio of 20 to 80 to It is preferable to use 4 to 15% by weight of a copolymer of 80/20 (weight ratio of E0ZP0) having a molecular weight of 9000 to 30000. When an ethylene oxide tetrahydrofuran copolymer is used, the copolymerization ratio of these monomers is 20/80 to 80/20 (weight ratio), and the average molecular weight is 1000 to 7000. Is preferably used in an amount of 1 to 10% by weight, particularly 1 to 5% by weight. Above all, when an ethylene oxide-tetrahydrofuran copolymer having no side wall is used, the effect of improving the oil film strength is large, and therefore, the generation and breakage of the polyester fiber yarn during high-speed spinning. The effect of suppressing the yarn is extremely large and preferable.
なお、 ポリオキシアルキレングリ コール共重合体の平均分子量の 上限值は特に限定されていないが、 それがあまりに大きい場合には 油剤の粘度が増大して高速走行糸条の動摩擦を脔めてしまう ことが あり、 また油剤エマルジョ ンの安定性も低下してスカムとして堆積 し易くなることがあるので、 用いるポリオキシアルキレングリコー ル共重合体の種類に応じて適当な平均分子量を選択することが好ま しい。  The upper limit of the average molecular weight of the polyoxyalkylene glycol copolymer is not particularly limited, but if it is too large, the viscosity of the oil agent increases and the dynamic friction of the high-speed running yarn is increased. In some cases, the stability of the oil agent emulsion is reduced, and the oil agent emulsion is likely to be deposited as scum. Therefore, it is preferable to select an appropriate average molecular weight according to the type of the polyoxyalkylene glycol copolymer used. New
また本発明で用いられるもう一つの必須成分 （ b ) である有機シ ロキサン化合物及び/又はフルォ口アルキル基舍有化合物の油剤中 含有量は、 油剤の有効成分の合計量の 0. 1〜 3重量％でぁり、 好ま しく は 0. 5〜 2重量％である。 このように成分 （ b ) を併用するこ とにより、 得られる油剤エマルジョ ンの表面張力が缄少し、 高速度 で走行する糸条への油剤均一付着性が向上し、 それとともに、 走行 糸条が該油剤ェマルジョ ンに接する際に受ける抵抗も低下して、 糸 の均質性及び製糸の工程調子が著しく改善される。 特に油剤ヱマル ジョ ンの表面張力が 3 O dyneZcii以下となる場合には、 成分 （ b ) の併用により油剤の均一付着性が極めて向上するとともに油剤付与 時の接触応力も低下し、 このため、 得られる油剤は 3000 111ノ分以上 の高速製糸に有効なものとなる。 その配合量が 0. 1重量％未満では 上記効果が得られず、 一方それが 3重量％を越えると、 得られる油 剤ェマルジョ ンの安定性が低下したり、 染色時に染色斑が発生し易 く なるので好ましく ない。 The content of the organic siloxane compound and / or the fluorinated alkyl group-containing compound, which is another essential component (b) used in the present invention, in the oil is 0.1 to 3 times the total amount of the active ingredients of the oil. % By weight, preferably from 0.5 to 2% by weight. By using the component (b) together in this way, the surface tension of the resulting oil emulsion is small, and the uniform adhesion of the oil agent to the yarn running at high speed is improved. The resistance to contact with the oil emulsion is also reduced, and the homogeneity of the yarn and the process condition of the yarn production are significantly improved. In particular, when the surface tension of the oil agent ヱ marion is less than 3 OdyneZcii, the combined use of the component (b) significantly improves the uniform adhesion of the oil agent and imparts the oil agent. The contact stress at the time also decreases, and the resulting oil agent is effective for high-speed spinning of 3000 111 min. If the amount is less than 0.1% by weight, the above effects cannot be obtained, while if it exceeds 3% by weight, the stability of the resulting oil-emulsion decreases, and stain spots easily occur during dyeing. It is not preferable because it becomes difficult.
上記のように油剤ェマルジョ ンの表面張力を低下させる有機シロ キサン化合物としては、 ァ ミ ノ変性シリ コーン、 ポリ エーテル変性 シリ コーン、 ポリ エステル変性シリ コーンなどの各種変性シリ コー ン、 及び例えば 3 0 es t ( 2 5て） 以下の低粘度を示すジメ チルシ リ コーンなど有機シロキサン化合物をあげることができ、 またフル ォロアルキル基舍有化合物としてはバーフルォ口ァルキルエーテル、 バーフルォロアルキルスルホネー ト、 パーフルォロアルキルスルホ ン酸アミ ドなどのフッ素化合物をあげることができる。 なお、 上記 表面張力の值は、 ウ ィルヘルミ一法によって 3 0てで測定した値で ある。  As described above, examples of the organic siloxane compound that lowers the surface tension of the oil emulsion include various modified silicones such as amino-modified silicone, polyether-modified silicone, and polyester-modified silicone; es t (25) Organic siloxane compounds such as dimethylsilicone exhibiting the following low viscosity can be mentioned. Examples of the fluoroalkyl group-containing compounds include verfluoroalkylalkyl ether and verfluoroalkylsulfonate. And fluorine compounds such as perfluoroalkylsulfonamide. The above-mentioned 張力 of the surface tension is a value measured at 30 by the Wilhelmy method.
本発明で用いる油剤は上記 3成分を必須成分として構成されてい ることが重要であるが、 この他に一般の乳化剤、 高扱アルコール、 高級脂肪酸、 グライコール類、 及び少量の有機もし く は無機化合物 の添加剤、 及び帯電防止剤、 脂肪酸のジエタノールァマイ ド等のァ マイ ド化合物を加えてもよい。  It is important that the oil agent used in the present invention is composed of the above three components as essential components.In addition to this, general emulsifiers, heavy alcohols, higher fatty acids, glycols, and a small amount of organic or inorganic A compound additive, an antistatic agent, and an amide compound such as diethanolamide of a fatty acid may be added.
上記のように、 本発明においては、 上記 3成分を必須成分とする 油剤ェマルジョ ンを、 SOOO m Z分以上の髙速紡糸の際に付与するこ とにより、 従来にない顕著な作用効果を奏し得たものであり、 これ らのいずれかが欠けても、 本発明の優れた効果を奏することはでき ない。  As described above, in the present invention, the oil agent emulsified with the above three components as an essential component is imparted at the time of high-speed spinning of at least SOOO mZ, thereby exhibiting a remarkable function and effect that has not been achieved in the past. Thus, even if any of these are missing, the excellent effects of the present invention cannot be achieved.
なお、 本発明の油剤ェマルジョ ンを付与する時期は、 溶融紡糸さ れたポリエステル繊維糸条が固化した時点以降であればいずれの時 点でもよいが、 通常は引取ローラの前で糸条に付与する。 好ましい 付与手段としては、 本発明の油剤エマルジョ ンを、 計量オイ リ ング ノ ズルを介して油剤純分付着量が糸条重量に対して、 例えば 0. 3 5 〜： I. 0重量％になるように付与することにより達成されるが、 これ に限定されるものではない。 The timing of applying the oil agent emulsion of the present invention may be any time after the time when the melt-spun polyester fiber yarn is solidified. It is usually applied to the yarn in front of the take-off roller. As a preferable means for applying, the oil agent emulsion of the present invention is obtained by, for example, 0.35 to: 1.0% by weight of the net amount of the oil agent via the measuring oiling nozzle with respect to the yarn weight. However, the present invention is not limited to this.
3000 m 分以上の高速度の溶融紡糸工程においては、 吐出口から 第一引取ローラに至るまでの走行糸条にはできるだけ無理な張力食 担をかけることなく、 高速度で走行する糸条に油剤を均一付着させ ること、 及び高速度で走行する糸条戡維簡の摩擦を低下させること が、 均質なポリエステル織維糸条を安定に製糸する上で重要なボイ ン トである。  In the high-speed melt spinning process of 3000 m or more, the running yarn from the discharge port to the first take-off roller is not subjected to excessive tension as much as possible. It is important to stably produce uniform polyester woven yarns by uniformly adhering and reducing the friction of the yarn running at high speed.
本発 ¾方法においては、 上述の如く油剤を水系ェマルジヨ ンとし て用いることにより、 その粘度を低下させ、 かつ特定のシ αキサン 化合物又はフッ素舍有化合物 （成分 （ b ) ) を併用することにより ェマルジョ ン表面張力を低下させているため、 髙速度で走行する糸 条への油剤の均一付着性が向上し、 且つ油剤付与装置と 条との接 触時に発生する負荷応力も低下している。  In the method of the present invention, the viscosity is reduced by using an oil agent as an aqueous emulsion as described above, and a specific siloxane compound or a fluorine-containing compound (component (b)) is used in combination. Since the surface tension of the emulsion is reduced, the uniformity of the oil agent to the yarn running at a high speed is improved, and the load stress generated when the oil agent applying device comes into contact with the yarn is also reduced.
また、 本発明の油剤には特定量のポリオキシアルキレングリ コー ル共重合体 （成分 （ a ) ) が E合されているため油剤系全体として の油膜強度が向上し、 3000m Z分以上の高速度の製糸条件下でも、 走行糸条に負荷される応力に油膜が充分酎えられるようになり、 こ のため、 油膜の潸滑特性の低下がなくなつている （接圧潤滑特性の 低下が少ない） 。  Further, since the oil agent of the present invention contains a specific amount of the polyoxyalkylene glycol copolymer (component (a)), the oil film strength of the entire oil agent system is improved, and the oil agent has a high oil film strength of 3000 mZ or more. Even under high-speed yarn production conditions, the oil film can sufficiently withstand the stress applied to the running yarn, and therefore, the oil film does not lose its lubricating properties. Few) .
さらに特定の一塩基酸エステルからなる平滑剤を油剤の主体成分 として含有しているので、 得られた油剤は全体として低い粘度を有 し、 このため、 高速製糸時の走行糸条と糸案内部材との摩擦も低下 させることができる。 上記各成分の効果が組み合わされることによって、 毛羽が少ない 高品位のボリエステル織維糸条を安定に製糸することが可能となり . 且つ得られるパッケージの捲姿も良好になる。 Further, since the lubricant contains a specific monobasic acid ester as a main component of the lubricant, the resulting lubricant has a low viscosity as a whole. Can also reduce friction. By combining the effects of the above-mentioned components, it becomes possible to stably produce a high-quality polyester woven fiber yarn with less fuzz. The obtained package also has a good winding appearance.
本発明の方法により得られる油剤付着ボリエステル繊維糸条は、 金属 ·繊維簡及び織維 ·繊維間の擦過耐久性に優れているため、 製 編織時に トラブルも発生し難く、 また高速製糸されたものであるた め、 良好な風合を有する布帛 （織物、 又は編物） を得ることができ る。 実施例  The oil agent-attached polyester fiber yarn obtained by the method of the present invention is excellent in durability against rubbing between metal and fiber, and between fibers and fibers, so that troubles do not easily occur at the time of knitting and weaving, and the yarn is produced at high speed. Therefore, a cloth (woven or knitted) having a good feeling can be obtained. Example
