Description
本発明は、乳剤の除去装置及びそれらを用いた乳剤が含浸されたフィラメント原糸の乳剤除去方法に関するものである。 The present invention relates to an emulsion removing apparatus and an emulsion removing method for filament yarn impregnated with an emulsion using them.
高分子の繊維を製造するためには、まず、高分子を紡糸してフィラメント原糸を製造し、このようなフィラメント原糸を延伸及びクリンピング(ｃｒｉｍｐｉｎｇ)、乾燥、切断(ｃｕｔｔｉｎｇ)、カージング(ｃａｒｄｉｎｇ)工程などによって不織布形態の繊維を製造する。この際、製造したい繊維の種類によって繊維の製造工程で繊維用乳剤又は紡糸用乳剤が使用されている。 In order to produce a polymer fiber, first, a polymer is spun to produce a filament yarn, and the filament yarn is drawn, crimped, dried, cut, and carded. ) A non-woven fiber is produced by a process or the like. At this time, a fiber emulsion or a spinning emulsion is used in the fiber production process depending on the type of fiber to be produced.
エレクトレット繊維の場合、まず、単繊維に紡糸されたフィラメントに繊維用乳剤を付与し、延伸及びクリンピング、乾燥、切断工程を通じて製造して、このように製造された単繊維は、カージング工程を経てフィルター濾材に製造される。この際、静電フィルターの製造時に、不織布上で静電化工程を経るが、単繊維に含浸されている繊維用乳剤の妨害で静電化がなされないという短点がある。これを解決するために、従来には、不織布の製造後に不織布上で繊維用乳剤を除去した。このような工程は、乾燥工程を２度経なければならないため、生産性の減少及び高費用の問題点が発生する。また、完成した不織布上で繊維用乳剤の除去がなされるが、除去がうまく行われないため、効率が低く、静電フィルターは低い捕集効率を示す。従って、不織布上での繊維用除去に比べ、効率の高い繊維用乳剤の除去が要求される。 In the case of electret fibers, first, a fiber emulsion is applied to the filaments spun into single fibers, and the filaments are manufactured through drawing, crimping, drying, and cutting processes. Manufactured into filter media. In this case, an electrostatic process is performed on the nonwoven fabric during the production of the electrostatic filter, but there is a shortcoming that the electrostaticization is not performed due to the interference with the fiber emulsion impregnated in the single fiber. In order to solve this, conventionally, the emulsion for fibers was removed on the nonwoven fabric after the nonwoven fabric was produced. Since such a process has to go through a drying process twice, a problem of reduced productivity and high cost occurs. Further, although the fiber emulsion is removed on the finished nonwoven fabric, the removal is not performed well, so the efficiency is low, and the electrostatic filter exhibits a low collection efficiency. Accordingly, it is required to remove the fiber emulsion more efficiently than the fiber removal on the nonwoven fabric.
高温用／高剛性繊維の場合、フィラメント繊維間の集束及び表面摩擦の低減のための紡糸用乳剤を付与して製造する。紡糸用乳剤は、一種の界面活性剤の役割をし、紡糸したフィラメント原糸間の融着を防止し、摩擦力を減少させて摩擦力による静電気の発生を防止することができる。しかし、紡糸用乳剤が含浸されたフィラメント原糸は、不織布の製造の際に、疎水化された繊維間の摩擦がオープニング及びカージング工程の不良の原因になる。また、繊維の表面に存在する紡糸用乳剤は、固有の粘着性によって繊維が凝集する現象を発生させるため、カージング工程で静電気の発生の原因となり、糸又は不織布及び織物の製造が難しくなる。従って、不織布の製造前に紡糸用乳剤の除去が要求される。 In the case of high-temperature / high-stiffness fibers, it is produced by applying a spinning emulsion for reducing the bundling between filament fibers and reducing surface friction. The spinning emulsion serves as a kind of surfactant, can prevent fusion between spun filament yarns, reduce frictional force, and prevent generation of static electricity due to frictional force. However, in the filament raw yarn impregnated with the spinning emulsion, friction between the hydrophobized fibers becomes a cause of defects in the opening and curling processes when the nonwoven fabric is produced. In addition, the spinning emulsion present on the surface of the fiber generates a phenomenon in which the fibers are aggregated due to inherent tackiness, which causes generation of static electricity in the curving process and makes it difficult to produce yarn or nonwoven fabric and woven fabric. Therefore, removal of the spinning emulsion is required before the production of the nonwoven fabric.
従って、本発明者は、繊維用乳剤又は紡糸用乳剤を不織布上ではなく、フィラメント原糸上で改めて除去する場合、不織布状態で乳剤を除去することに比べ、除去効率が改善されたことを確認し、そのための乳剤の除去装置及びそれを用いた乳剤が含浸されたフィラメント原糸の乳剤の除去方法である本発明を完成した。 Therefore, the present inventor confirmed that the removal efficiency was improved when removing the emulsion for fiber or spinning on the filament yarn instead of on the nonwoven fabric, compared to removing the emulsion in the nonwoven fabric state. Thus, the present invention, which is an emulsion removing apparatus and a method for removing the filament yarn impregnated with the emulsion using the same, was completed.

以下、図面を参考して本発明による乳剤の除去装置の一実施例を説明する。 An embodiment of an emulsion removing apparatus according to the present invention will be described below with reference to the drawings.
本発明による乳剤の除去装置は、フィラメント原糸が投入される原糸投入部(１０)、乳剤を除去するために洗浄及び脱水作用をする第１水槽(１００)及び第２水槽(２００)、乳剤の除去が完了したフィラメント原糸が次の工程のために吐出される原糸の吐出部(２０)を含む。 The emulsion removing apparatus according to the present invention includes a yarn feeding unit (10) into which filament filament yarn is fed, a first water tank (100) and a second water tank (200) that perform washing and dehydration to remove the emulsion, The filament raw yarn from which the removal of the emulsion has been completed includes a raw yarn discharge section (20) from which the filament raw yarn is discharged for the next step.
ここに適用される水槽の個数に制限がないのはもちろん、本発明者は、多数の実験を通じて２つの水槽(１００、２００)を使用することが経済性かつ乳剤除去の性能を同時に満足させるのに最適であることを確認した。 Of course, the number of water tanks applied here is not limited, and the inventor of the present invention uses two water tanks (100, 200) through a large number of experiments to satisfy economic and emulsion removal performance at the same time. Confirmed to be optimal.
まず、原糸投入部(１０)を通じて乳剤が含浸されたフィラメント原糸が投入される。 First, the filament yarn impregnated with the emulsion is fed through the yarn feeding section (10).
本発明は、不織布形態で乳剤を除去することではなく、フィラメント原糸状態で乳剤を除去することを主な目的とすることを再度強調する。 The present invention again emphasizes that the main purpose is not to remove the emulsion in the form of a non-woven fabric, but to remove the emulsion in the filament yarn state.
原糸投入部(１０)を通じて投入されたフィラメント原糸は、第１水槽(１００)に投入され１次の乳剤除去工程が行われる。 The filament yarn fed through the yarn feeding section (10) is put into the first water tank (100) and the primary emulsion removing step is performed.
第１水槽(１００)の内側には、フィラメント原糸の移動方向を転換するための多数の糸巻き(１１０)、乳剤を洗浄するためにフィラメント原糸に水を噴射するための多数のウォータージェットノズル(１２０)及びウォータージェットノズル(１２０)を通じて噴射された水をフィラメント原糸の全体表面に均等に噴射させるためのウォータージェットノズル(１２０)に対向して位置する反射板(１３０)が位置する。 Inside the first water tank (100), there are a number of spools (110) for changing the moving direction of the filament yarn, and a number of water jet nozzles for spraying water onto the filament yarn to wash the emulsion. (120) and a reflecting plate (130) positioned opposite to the water jet nozzle (120) for spraying water sprayed through the water jet nozzle (120) uniformly on the entire surface of the filament yarn.
ウォータージェットノズル(１２０)は、供給管(１２５)を通じて外部から流入された水をフィラメント原糸に噴射することで、乳剤を洗浄する機能をする。 The water jet nozzle (120) has a function of washing the emulsion by spraying water introduced from the outside through the supply pipe (125) onto the filament yarn.
高い水圧で水を噴射できるどのような形式のノズルも使用可能である。 Any type of nozzle that can inject water at high water pressure can be used.
ここで、ウォータージェットノズル(１２０)は、フィラメント原糸の移動方向に対して垂直に配置されるのが洗浄効果の増進のために好ましい。 Here, the water jet nozzle (120) is preferably disposed perpendicular to the moving direction of the filament raw yarn in order to enhance the cleaning effect.
反射板(１３０)は、ウォータージェットノズル(１２０)の噴射方向に対して垂直に、すなわち、フィラメント原糸を基準に、ウォータージェットノズル(１２０)に対向して位置する。 The reflector (130) is positioned perpendicular to the jet direction of the water jet nozzle (120), that is, facing the water jet nozzle (120) with reference to the filament yarn.
ウォータージェットノズル(１２０)で噴射された水は、フィラメント原糸を通過するのはもちろん、反射板を通じてウォータージェットノズル(１２０)の水噴射の方向と反対方向にも水が噴射される効果を持つことができ、それによって、フィラメント原糸の全体表面に均一に水が噴射され洗浄効果を高めることができる。 The water jetted by the water jet nozzle (120) not only passes through the filament yarn, but also has the effect of jetting water in the direction opposite to the water jet direction of the water jet nozzle (120) through the reflector. Accordingly, water can be sprayed uniformly on the entire surface of the filament yarn, thereby enhancing the cleaning effect.
糸巻き(１１０)及びこれによるウォータージェットノズル(１２０)と反射板(１３０)の個数には、制限はないが、図面には、それぞれ８個が具備された実施例を図示する。 There are no restrictions on the number of the spool (110) and the number of the water jet nozzles (120) and the reflectors (130), but in the drawings, there are illustrated embodiments each including eight.
第１水槽の末端には、洗浄作用が完了したフィラメント原糸を脱水するための脱水部が位置し、脱水部は、脱水用の空圧シリンダーローラー(１４０)、サクション部(１５１)、ブロアー(１５３)を含む。 At the end of the first water tank, a dewatering unit for dewatering the filament yarn that has been cleaned is positioned. The dewatering unit includes a pneumatic cylinder roller (140) for dehydration, a suction unit (151), and a blower ( 153).
第１水槽(１００)の内側で乳剤が洗浄されたフィラメント原糸には、水が残っているが、ます、脱水用の空圧シリンダーローラー(１４０)に流入されることで、空圧を利用して脱水が行われる。 Water remains in the filament yarn from which the emulsion has been washed inside the first water tank (100). However, air is used by flowing into the pneumatic cylinder roller (140) for dehydration. Then dehydration is performed.
次に、フィラメント原糸は、サクション部(１５１)を通過しながら、セクションホーム(１５２)での吸気作用によりさらに脱水が行われる。 Next, the filament yarn is further dehydrated by the intake action in the section home (152) while passing through the suction portion (151).
次に、フィラメント原糸は、ブロアー(１５３)を通過しながら、ブロアーホーム(２５３参照)での排気作用によりさらに脱水が行われる。 Next, the filament raw yarn is further dehydrated by the exhaust action in the blower home (refer to 253) while passing through the blower (153).
このようなフィラメント原糸は、第１水槽(１００)を通過しながら、ウォータージェットノズル(１２０)及び反射板(１３０)の相互作用によって洗浄が行われ、次に、脱水用の空圧シリンダーローラー(１４０)、セクション部(１５１)及びブロアー (１５３)によって脱水が行われる。このような一連の作用を通じて乳剤の除去効率を向上させることができる。 The filament yarn is washed by the interaction of the water jet nozzle (120) and the reflector (130) while passing through the first water tank (100), and then dehydrated pneumatic cylinder roller. Dehydration is performed by (140), section (151) and blower (153). Emulsion removal efficiency can be improved through such a series of actions.
第１水槽(１００)を通過したフィラメント原糸は、再び第２水槽(２００)を通過しながら、前述した全ての作用が繰り返されるのが好ましい。 The filament yarn that has passed through the first water tank (100) preferably repeats all of the above-described actions while passing through the second water tank (200) again.
そのために、第２水槽(２００)にもウォータージェットノズル(２２０)、反射板(２３０)が位置し、脱水部、すなわち、空圧シリンダーローラー(２４０)、セクション部(２５１)及びブロアー(２５３)が具備される。 For this purpose, the water jet nozzle (220) and the reflector (230) are also located in the second water tank (200), and the dewatering part, that is, the pneumatic cylinder roller (240), the section part (251) and the blower (253). Is provided.
同様に、糸巻き(１１０)及びそれによるウォータージェットノズル(１２０)と反射板(１３０)の個数には、制限はないが、図面では、便宜のために４つが具備された実施例を図示する。 Similarly, the number of the spool (110) and the number of the water jet nozzle (120) and the reflecting plate (130) is not limited, but in the drawing, for convenience, four embodiments are shown.
一方、第１水槽(１００)及び第２水槽(２００)の内側の流体の温度は、常温で８０℃まで制御され得、フィラメント原糸の処理速度は、約８０ｍ／ｍｉｎである。 On the other hand, the temperature of the fluid inside the first water tank (100) and the second water tank (200) can be controlled up to 80 ° C. at room temperature, and the processing speed of the filament yarn is about 80 m / min.
第１水槽(１００)及び第２水槽(２００)を通過しながら、洗浄及び脱水が行われることから、乳剤が除去されたフィラメント原糸が吐出部(２０)を通じて乳剤の除去装置から吐出され、次の工程に移動する。 Since the washing and dewatering are performed while passing through the first water tank (100) and the second water tank (200), the filament yarn from which the emulsion has been removed is discharged from the emulsion removing device through the discharge section (20), Move to the next step.
さらに、本発明は、前記乳剤の除去装置で乳剤が含浸されたフィラメント原糸の乳剤の除去方法において、乳剤が含浸されたフィラメント原糸に水を噴射して乳剤を洗浄する段階(段階１)；及び前記洗浄されたフィラメント原糸を脱水する段階(段階２)を含む乳剤の除去方法を提供する。 Furthermore, the present invention provides a method for washing an emulsion by spraying water onto a filament yarn impregnated with an emulsion in the method of removing an emulsion of a filament yarn impregnated with an emulsion by the emulsion removing apparatus (step 1). And a method for removing the emulsion comprising the step of dehydrating the washed filament yarn (step 2).
前記乳剤の除去方法は、エレクトレット繊維の製造過程で繊維用乳剤を除去したり、高温用／高剛性繊維の製造過程における紡糸用乳剤の除去に使用され得る。 The method for removing the emulsion can be used for removing the emulsion for fibers in the production process of electret fibers or for removing the emulsion for spinning in the production process of high temperature / high rigidity fibers.
エレクトレット繊維の場合、まず、単繊維に紡糸されたフィラメントに繊維用乳剤を付与して延伸及びクリンピングした後、本発明による前記乳剤の除去方法で繊維用乳剤を除去することができる。乳剤を除去した後、乾燥及び切断工程を通じて、単繊維を製造し、カージング工程を経て不織布形態のフィルター濾材を作ることができる。このような過程で製造された不織布形態のフィルター濾材には、繊維用乳剤が含まれていないため、静電化が容易になされる。従来には、繊維用乳剤を除去せず、不織布形態のフィルター濾材を製造したため、製造された不織布にも繊維用乳剤が含まれ、静電化のための追加的な乳剤の除去が必要であった。また、不織布を製造した後に乳剤を除去するので、乳剤を除去するための複雑な工程と費用が増加する問題点があった。しかし、本発明では、不織布の製造以前に繊維用乳剤を除去することで、乳剤の除去工程を単純化し、費用を削減する利点がある。 In the case of electret fibers, first, a fiber emulsion is applied to a filament spun into a single fiber, followed by stretching and crimping, and then the fiber emulsion can be removed by the method for removing an emulsion according to the present invention. After removing the emulsion, a single fiber is manufactured through a drying and cutting process, and a filter medium in the form of a nonwoven fabric can be made through a cursing process. Since the filter medium in the form of a nonwoven fabric manufactured in such a process does not contain a fiber emulsion, it can be easily electrostaticized. In the past, since the filter media in the form of a nonwoven fabric was manufactured without removing the fiber emulsion, the manufactured nonwoven fabric also contained a fiber emulsion, and it was necessary to remove the additional emulsion for electrostaticization. . In addition, since the emulsion is removed after the nonwoven fabric is produced, there is a problem in that the complicated process and cost for removing the emulsion are increased. However, the present invention has the advantage of simplifying the emulsion removal process and reducing costs by removing the fiber emulsion prior to the production of the nonwoven fabric.
高温用／高剛性の繊維の場合、高温用／高剛性繊維の原料になる高分子と紡糸用乳剤を混合して紡糸しフィラメント原糸を製造した後、本発明による前記乳剤の除去方法で紡糸用乳剤を除去することができる。紡糸用乳剤を除去した後、クリンピング工程を経ながら、繊維用乳剤を付与してオープニング及びカージング工程などを経て不織布形態の織物を製造することができる。従来には、紡糸用乳剤を除去してない状態で工程が進み、紡糸用乳剤により疎水化された繊維間の摩擦が、オープニング及びカージング工程不良の原因になる。また、繊維の表面に存在する紡糸用乳剤は、固有の粘着性による繊維の凝集現象を発生させ、カージング工程で静電気発生の原因になり、糸又は不織布及び織物の製造が難しくなる。しかし、本発明では、紡糸用乳剤をフィラメント原糸で除去した帯電防止の効果が大きい繊維用乳剤を再度付与することによって、カージング工程時のウェブ形成が効率的である。 In the case of high-temperature / high-rigidity fibers, a raw material for high-temperature / high-rigidity fibers and a spinning emulsion are mixed and spun to produce a filament yarn, and then spun by the emulsion removal method according to the present invention. The emulsion can be removed. After removing the spinning emulsion, it is possible to produce a non-woven fabric in the form of a nonwoven fabric by applying a fiber emulsion while undergoing a crimping process and through an opening and a curing process. Conventionally, the process proceeds in a state where the spinning emulsion is not removed, and friction between fibers hydrophobized by the spinning emulsion causes poor opening and casing processes. In addition, the spinning emulsion present on the surface of the fiber generates a phenomenon of fiber aggregation due to inherent tackiness, which causes generation of static electricity in the casing process, and makes it difficult to produce yarn or nonwoven fabric and woven fabric. However, in the present invention, the web formation during the cursing process is efficient by re-applying the fiber emulsion having a large antistatic effect obtained by removing the spinning emulsion with the filament yarn.
前記段階１は、フィラメント原糸に含浸されている乳剤を、水を噴射して除去する段階として、前記乳剤の除去装置に具備されたウォータージェットノズルを利用する段階である。
The
前記段階２は、前記乳剤が洗浄されたフィラメント原糸に含まれた水を除去するための段階として、前記乳剤の除去装置に具備された脱水部を利用する段階である。 The step 2 is a step of using a dewatering unit provided in the emulsion removing apparatus as a step for removing water contained in the filament yarn from which the emulsion has been washed.
前記フィラメント原糸は、ポリプロピレン(ＰＰ)、ポリエチレン(ＰＥ)、ポリカーボネート(ＰＣ)、ポリビニリデンフルオリド(ＰＶＤＦ)、ポリメタクリル酸メチル(ＰＭＭＡ)、アラミド(Ａｒａｍｉｄ)、ポリフェニレンスルファイド(ＰＰＳ)、ポリテトラフルオロエチレン(ＰＴＦＥ)又はポリシクロへキシレンジメチレンフィラメント原糸を使用することができる。 The filament yarn is made of polypropylene (PP), polyethylene (PE), polycarbonate (PC), polyvinylidene fluoride (PVDF), polymethyl methacrylate (PMMA), aramid, polyphenylene sulfide (PPS), poly Tetrafluoroethylene (PTFE) or polycyclohexylene dimethylene filament yarn can be used.
前記フィラメント原糸中、ポリプロピレン、ポリエチレン、ポリカーボネート、ポリビニリデンフルオリド又はポリメタクリル酸メチル(PMMA)は、エレクトレット繊維の製造に使用され得る。本発明による繊維用乳剤の除去を実施した後、円滑なエレクトロチャージング(Ｅｌｅｃｔｒｏ Ｃｈａｒｇｉｎｇ)加工が可能である。繊維用乳剤の除去後に静電気が一部発生するが、繊維の乳剤を除去していない未処理の一般繊維を２０〜３０％混合すると効率的なカージング工程が可能である。それによって製造された不織布にコロナ帯電のようなその他のチャージング方式を活用することができ、濾材に静電気力を付与して圧力損失が低いと同時に、高い捕集効率を示す優秀な濾材を生産することができる。 Among the filament yarns, polypropylene, polyethylene, polycarbonate, polyvinylidene fluoride or polymethyl methacrylate (PMMA) can be used for producing electret fibers. After removing the fiber emulsion according to the present invention, a smooth electrocharging process is possible. A part of static electricity is generated after the removal of the fiber emulsion. However, when 20 to 30% of untreated general fibers from which the fiber emulsion has not been removed are mixed, an efficient caging process is possible. Other charging methods such as corona charging can be applied to the non-woven fabric produced thereby, and the filter medium is applied with electrostatic force to produce a low pressure loss and at the same time an excellent filter medium with high collection efficiency. can do.
また、前記フィラメント原糸中、アラミド、ポリフェニレンスルファイド、ポリテトラフルオロエチレン又はポリシクロへキシレンジメチレンフィラメント原糸は、高温用／高剛性繊維の製造に使用され得る。 In the filament yarn, aramid, polyphenylene sulfide, polytetrafluoroethylene or polycyclohexylene dimethylene filament yarn can be used for the production of high temperature / high rigidity fibers.
本発明による乳剤の除去方法によって、不織布上で乳剤の除去が行われた従来の方法とは異なり、フィラメント原糸上で乳剤を除去することができる。乳剤と不織布の接触面積より、乳剤とフィラメント原糸の接触面積が少ないため、乳剤の除去工程が簡素化され、費用も削減することができ、特に、エレクトレット繊維又は高温用／高剛性繊維の製造に有効に適用することができる。 Unlike the conventional method in which the emulsion is removed on the nonwoven fabric, the emulsion can be removed on the filament yarn by the method for removing the emulsion according to the present invention. Since the contact area between the emulsion and the filament yarn is smaller than the contact area between the emulsion and the nonwoven fabric, the process of removing the emulsion can be simplified and the cost can be reduced. Especially, the production of electret fibers or high temperature / high rigidity fibers It can be effectively applied to.
