[0002] 合成繊維の延伸装置としては、繊維を供給する第 1ローラと、繊維を延伸する第 2口 ーラと、これら第 1ローラと第 2ローラとの間に配置され、繊維に走行抵抗を付与する 抵抗体を有する加熱槽からなるものが知られている（例えば、特許文献 1参照）。 これらの延伸装置は、繊維に走行抵抗を付与する抵抗体と繊維との係合度合を調 節手段によって調整し、抵抗体から繊維に付与する走行抵抗を加減できるようにした ものである。これらの延伸装置にあっては、単繊維あるいは数本の繊維を延伸する際 には何ら問題なかった。  [0002] As a synthetic fiber drawing device, a first roller for supplying fibers, a second roller for drawing fibers, and a roller between the first roller and the second roller are provided. A heating tank having a resistor provided with a resistance is known (for example, see Patent Document 1). In these drawing apparatuses, the degree of engagement between the resistor and the fiber that imparts running resistance to the fiber is adjusted by adjusting means so that the running resistance applied to the fiber from the resistor can be adjusted. In these stretching apparatuses, there was no problem when stretching a single fiber or several fibers.

As a result, there was a problem that the fiber in the center portion was whitened or the yarn was broken. In addition, if the central portion is to be sufficiently softened, a new problem arises in that the surface layer portion that has been excessively heated is melted and thread breakage occurs.
[0004] 特に、ポリ塩化ビュル樹脂製の人工毛髪用合成繊維の場合、未延伸の繊維は 120 一 320デニールであって一般用との合成繊維より比較的繊維径が大きい繊維であり 、さらに、加熱による軟化の発現が他の原料力 成る合成繊維と大きく異なり、また、 得られた製品が人工毛髪と云う特殊な分野であるとともに、極めて厳しい品質管理が 求められるため、他分野の技術の応用が極めて困難であった。  [0004] In particular, in the case of synthetic fibers for artificial hair made of polychlorinated vinyl resin, the unstretched fibers are 120 to 320 denier and have a fiber diameter larger than that of synthetic fibers for general use. The expression of softening due to heating is significantly different from synthetic fibers that use other raw materials.The obtained product is a special field called artificial hair, and extremely strict quality control is required. Was extremely difficult.
[0005] 繊維の白化とは繊維が延伸された際に、繊維を構成する樹脂組成物がミクロ的に 切断して繊維の表面が白くなつてしまう現象をいい、糸切れとは、白化現象が進行し たり、溶融しすぎた結果、繊維自体が切断してしまう現象を云う。 [0005] Whitening of a fiber is a phenomenon in which when a fiber is stretched, a resin composition constituting the fiber is cut microscopically, and the surface of the fiber becomes white. Progress Or a phenomenon in which the fibers themselves are cut as a result of excessive melting or melting.

発明を実施するための最良の形態 [0021] 本発明における加熱 ·抵抗付与装置は、断面が円状の繊維束を上下方向又は左 右方向より挟み込んで帯状に拡幅変形させると共に、繊維束に摺動抵抗を付与する ためのものであるとともに、拡幅変形させた繊維束を効果的に加熱するものである。こ こで、抵抗付与装置の形状は、それぞれ加熱可能な複数の支持体と、隣り合う 2つの 支持体の中間ないし中間付近に設けられた、加熱可能な加圧体とからなるものであ る。 BEST MODE FOR CARRYING OUT THE INVENTION [0021] The heating / resistance applying device according to the present invention is used for sandwiching a fiber bundle having a circular cross section from above and below or right and left to widen and deform it into a band shape, and to provide sliding resistance to the fiber bundle. In addition, the fiber bundle that has been subjected to the widening deformation is effectively heated. Here, the shape of the resistance applying device includes a plurality of supports that can be heated, and a pressurizable body that can be heated and is provided at or near the middle of two adjacent supports. .
[0022] すなわち、加熱'抵抗付与装置は、繊維束を帯状に拡幅させて変形させることで、 繊維束の表層部と中心部を近接させて、繊維束全体を均一に加熱し、軟化させるこ とができるものであり、さらに繊維束に摺動抵抗を与えることで、繊維の延伸開始位 置を固定して繊維を均一に延伸できるようにしたものである。  [0022] That is, the heating and resistance imparting device expands and deforms the fiber bundle in a belt-like shape, thereby bringing the surface layer portion and the center portion of the fiber bundle close to each other and uniformly heating and softening the entire fiber bundle. Further, by giving sliding resistance to the fiber bundle, the drawing start position of the fiber is fixed so that the fiber can be drawn uniformly.
[0023] なお、加熱'抵抗付与装置における複数の、棒状の支持体は、通常、第 1ローラの 繊維束接触面と第 2ローラの繊維束接触面と含む平面に、その繊維との接触面が位 置するように配するが、装置製作上の必要がある場合、あるいは、特に高い摺動抵抗 を付与しょうとする場合などではこの限りでない。  [0023] The plurality of rod-shaped supports in the heating and resistance applying device usually have a contact surface with the fiber on a plane including the fiber bundle contact surface of the first roller and the fiber bundle contact surface of the second roller. However, this does not apply when it is necessary to manufacture the equipment or when it is intended to provide particularly high sliding resistance.
[0024] 本発明における支持体及び加圧体の形状は本発明の効果を損なわない限りにお いて特に限定されないが、これらは繊維束と接摺する接触部材であるため、なめらか な形状であることが必要で、例えば断面が円形、楕円形、多角形の棒状体や板状体 などが挙げられ、これらの 1種またはこれらを組み合わせて採用できる。なお、形状と して棒状体を採用した際には直径 10— 150mm、板状体を採用した際には厚さ 5— 30mmとし、共に繊維との接触部に半径 5— 75mmの曲面加工を施したものが望ま しい。  [0024] The shapes of the support and the pressurizing body in the present invention are not particularly limited as long as the effects of the present invention are not impaired. However, since these are contact members that come into contact with the fiber bundle, they have a smooth shape. For example, a rod, plate, or the like having a circular, elliptical, or polygonal cross section may be used, and one or a combination of these may be employed. When a rod-shaped body is used, the diameter is 10-150 mm, and when a plate-shaped body is used, the thickness is 5-30 mm. It is desirable to have done it.
[0025] また、本発明における支持体及び加圧体の材料としては、鉄、ステンレス、銅、真鍮 等の金属材料や、セラミックス等の無機材料が挙げられ、これらから適宜選択して採 用すればよい。  [0025] Examples of the material of the support and the pressing body in the present invention include metal materials such as iron, stainless steel, copper, and brass, and inorganic materials such as ceramics. Just fine.
[0026] 本発明における支持体及び加圧体の材料は加熱可能であることが必要である。カロ 熱槽で雰囲気温度を高めても、繊維自体が延伸可能な温度とするには、加熱槽の大 きさを巨大なものとしても充分な加温ができなレ、。繊維束と接触する支持体及び加熱 体が加熱されていることで、それらと繊維束との接触による伝熱で、繊維束をその内 部まで確実に加熱することができる。 [0026] The materials of the support and the pressing body in the present invention need to be heatable. Caro Even if the temperature of the heating tank is large, even if the temperature of the heating tank is huge, even if the temperature of the heating tank is enormous, it is not possible to sufficiently heat the fiber itself. Since the support and the heating element that come into contact with the fiber bundle are heated, the fiber bundle is Can be reliably heated up to the part.
[0027] これら支持体及び加圧体の加熱は、これらに供給される電気エネルギーによる抵 抗加熱等により行うことができ、あるいは、外部からこれらの内部に供給される熱媒と しての加熱用流体によりおこなうことができる。前者の場合では、これら支持体、加圧 体及びこれらの加熱のための設備の製造コストは安価となる力 ランニングコストが高 くなる。後者の場合では加熱流体を加熱しやすいため、前者よりもランニングコストが 低くなるとともに、これら支持体、加圧体及びこれらの加熱のための設備の製造コスト が高いものとなる。  [0027] Heating of the support and the pressurized body can be performed by resistance heating or the like using electric energy supplied thereto, or heating as a heat medium supplied from the outside to the inside thereof. It can be performed with a working fluid. In the former case, the production cost of the support, the pressurized body and the equipment for heating them is reduced, and the force running cost is increased. In the latter case, the heating fluid is easily heated, so that the running cost is lower than in the former case, and the manufacturing cost of these supports, pressurizing bodies and equipment for heating them is higher.
[0028] 本発明の加熱槽において、繊維束を加熱軟化させる手段は従来公知のものを採用 でき、例えば、電熱、蒸気、温水、温油等がある。なお、加熱温度は、延伸する合成 繊維の素材に合わせて適宜設定すればよい。  [0028] In the heating tank of the present invention, means for heating and softening the fiber bundle may be a conventionally known means, for example, electric heating, steam, hot water, hot oil and the like. The heating temperature may be appropriately set according to the material of the synthetic fiber to be drawn.
[0029] 本発明では、このような第 1ローラと第 2ローラとの間に配置した中空箱状の加熱槽 の内部に導入して加熱軟化させるときに、加熱槽内で、繊維束を帯状にその幅を広 げると共に、繊維束を加熱された接触部材、すなわち、共に加熱された支持体及び 加圧体と接触させることによる接触加熱により、加熱槽だけでの加熱では果たせなか つた、繊維束中央部の繊維の充分な加熱も可能となり、その結果、白化や、糸切れを 未然に防止しながら、第 1ローラと第 2ローラとにより所定の倍率に延伸することが可 能となる。  [0029] In the present invention, when the fiber bundle is introduced into the hollow box-shaped heating tank disposed between the first roller and the second roller to be heated and softened, the fiber bundle is strip-shaped in the heating tank. In addition to increasing the width of the fiber bundle, the contact heating by bringing the fiber bundle into contact with the heated contact member, that is, the support and the pressurized body that were heated together, could not be achieved by heating in the heating tank alone. Sufficient heating of the fiber in the center of the fiber bundle is also possible, and as a result, it is possible to stretch the film at a predetermined magnification by the first roller and the second roller while preventing whitening and yarn breakage. .

[0031] 本発明において合成樹脂として人工毛髪に最適なポリ塩化ビュル樹脂を採用する 場合、 目的に応じてポリ塩化ビニル樹脂組成物に使用される公知の添加剤を本発明 の効果を阻害しない範囲で添加できる。添加剤としては、加工助剤、強化剤、紫外線 吸収剤、酸化防止剤、帯電防止剤、充填剤、難燃剤、顔料、初期着色改善剤、導電 性付与剤、表面処理剤、光安定剤、香料等がある。  [0031] When the polyvinyl chloride resin most suitable for artificial hair is employed as the synthetic resin in the present invention, known additives used in the polyvinyl chloride resin composition may be used according to the purpose without impairing the effects of the present invention. Can be added. Additives include processing aids, strengthening agents, ultraviolet absorbers, antioxidants, antistatic agents, fillers, flame retardants, pigments, initial color improvers, conductivity-imparting agents, surface treatment agents, light stabilizers, There are fragrances.
[0032] ここで、支持体を 2つ、加圧体を 1つそれぞれ有する加熱'抵抗付与装置での場合 には、その繊維束の進行方向上流側に設置された第 1支持体は、第 1ローラから供 給された繊維束を加熱槽の繊維束導入口へ安定的に導入するものである。ここで第 1支持体の設置位置は、加熱槽の繊維束の導入口より第 1ローラ側であると、繊維束 を加熱槽に安定的に導入できなくなって繊維の白化や糸切れが発生し、あるいは、 加熱槽の中央部より繊維束進行方向下流の方向側であると繊維束が延伸時に振動 して繊維の白化や糸切れが発生してしまうため、加熱槽の繊維束導入口と加熱槽の 中央との間の位置であることがよい。  [0032] Here, in the case of a heating resistance applying device having two support members and one pressurizing member, the first support member installed on the upstream side in the traveling direction of the fiber bundle is the first support member. The fiber bundle supplied from one roller is stably introduced into the fiber bundle inlet of the heating tank. Here, if the first support is installed on the first roller side from the fiber bundle inlet of the heating tank, the fiber bundle cannot be stably introduced into the heating tank, causing fiber whitening and yarn breakage. Alternatively, if the fiber bundle is located downstream of the center of the heating tank in the direction in which the fiber bundle travels, the fiber bundle vibrates at the time of drawing, causing whitening or breakage of the fiber. It should be located between the center of the tank.
[0033] さらに、第 1支持体よりも繊維束の進行方向下流側に設置された第 2支持体は、後 述する加圧体によって摺動抵抗が付与された繊維束を、加熱槽の排出口から安定し て排出するためのものである。ここで第 2支持体の設置位置は、加熱槽の全長ゃ繊 維東の移動速度にもよるが、第 1支持体力も繊維束進行方向下流の方向へ 65— 55 Ommの位置に配置されていることが好ましい。ここで、 65mm未満の位置であると繊 維束にカゝかる抵抗が大きくなりすぎて繊維が糸切れしてしまレヽ、 550mmを超えた位 置であると繊維束が帯状に拡幅 ·変形しなくなって均一に加熱されなくなり繊維の白 化が発生してしまう。  [0033] Further, the second support, which is provided downstream of the first support in the direction of travel of the fiber bundle, discharges the fiber bundle, to which sliding resistance has been imparted by the pressurizing body described later, from the heating tank. This is for stable discharge from the exit. Here, the installation position of the second support depends on the total length of the heating tank and the moving speed of the fiber east, but the first support is also located at a position of 65-55 Omm in the downstream direction in the fiber bundle traveling direction. Is preferred. Here, if the position is less than 65 mm, the resistance to covering the fiber bundle becomes too large, and the fiber breaks.If the position is more than 550 mm, the fiber bundle expands and deforms into a belt shape. As a result, the fibers are not uniformly heated and whitening of the fibers occurs.
[0034] 加圧 ·抵抗付与装置の加圧体は、上記第 1支持体及び第 2支持体と相俟って、断 面円状の繊維束を挟み込んで、帯状に拡幅 ·変形させるとともに、繊維束に摺動抵 抗を付与するためのものである。ここで、加圧体が、該第 1支持体の繊維束摺接面と 第 2支持体の繊維束摺接面とを含む平面の、第 1支持体力 繊維束進行方向下流 の方向に 50— 350mmの位置力 垂直に 10— 200mm離間した位置に配置されて レ、ることが望ましい。 [0034] Pressurizing The pressurizing body of the resistance applying device, together with the first support and the second support, is cut off. This is for sandwiching a plane-shaped fiber bundle, widening and deforming it into a belt shape, and for imparting sliding resistance to the fiber bundle. In this case, the pressing body is 50-degree in the direction downstream of the first supporting member force fiber bundle advancing direction on the plane including the fiber bundle sliding contact surface of the first support and the fiber bundle sliding contact surface of the second support. Position force of 350mm It is desirable to be placed vertically 10-200mm apart.
[0035] すなわち、第 1支持体から繊維束進行方向への変位が 50mm未満であると繊維束 にかかる抵抗が大きくなりすぎて繊維が糸切れしやすくなり、 550mm超であると繊維 束が効果的に帯状に拡幅 ·変形されなくなって、均一加熱が困難となり、その結果、 繊維の白化が発生しやすくなる。  That is, if the displacement from the first support in the fiber bundle advancing direction is less than 50 mm, the resistance applied to the fiber bundle becomes too large, and the fiber is likely to be broken. If it is more than 550 mm, the fiber bundle is effective. The band is not widened and deformed, and uniform heating becomes difficult. As a result, the fiber is apt to whiten.
[0036] また、加圧体の上記平面からの垂直な離間距離が、 10mm未満であると、繊維束 が帯状に変形しなくなって均一に加熱されなくなり繊維の白化が発生しやすくなり、 2 00mmを超えてしまうと繊維束に力かる抵抗が大きくなりすぎて繊維が糸切れしやす くなるため、加圧体の上記平面からの垂直な離間距離は 10— 200mmの位置がよい 実施例  [0036] When the vertical separation distance of the pressurized body from the plane is less than 10 mm, the fiber bundle does not deform into a belt shape, is not uniformly heated, and the fiber is apt to whiten. If the pressure exceeds the limit, the resistance to the fiber bundle becomes too large and the fiber is apt to break, so the vertical distance of the pressurized body from the above plane is preferably 10 to 200 mm.
