本発明は、熱可塑性樹脂フィルムの加熱方法に関するも
のであり、詳しくは、熱可塑性樹脂フィルムを延伸又は
熱処理温度まで加熱する際に問題となる、静電気障害を
解消した熱可塑性樹脂フィルムの加熱方法に関するもの
である。[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a method for heating a thermoplastic resin film, and more specifically, it relates to a method for heating a thermoplastic resin film, and more specifically, it relates to a heating method for a thermoplastic resin film, and more specifically, it relates to a method for heating a thermoplastic resin film, and more specifically, it is a method for heating a thermoplastic resin film to a stretching or heat treatment temperature. , relates to a method of heating a thermoplastic resin film that eliminates static electricity interference.
一般的に、フィルムを延伸又は熱処理するに適した温度
まで予熱する方法には、複数個の加熱ロールが用いられ
る。そして、予熱されたフィルムは、延伸工程において
は、複数個のロール間の周速差によって延伸され、熱処
理工程においては、複数個のロール間のフィルムの張力
を制御する等して熱処理される。Generally, a plurality of heating rolls are used in the method of preheating a film to a temperature suitable for stretching or heat treating. In the stretching process, the preheated film is stretched by a difference in circumferential speed between the plurality of rolls, and in the heat treatment process, it is heat-treated by controlling the tension of the film between the plurality of rolls.
従来より、上記の加熱ロールには、金属ロール、金属ロ
ール表面にセラミックや樹脂をコーティングしたロール
、同じく表面にゴムを被覆したロール（ゴムロール）等
が適宜使用されており、実際には、所望の予熱温度にお
いてフィルムとロールが粘着しないようなロール表面材
質が選定される。Conventionally, metal rolls, rolls whose surfaces are coated with ceramic or resin, rolls whose surfaces are coated with rubber (rubber rolls), etc., have been used as appropriate for the above-mentioned heating rolls. The roll surface material is selected so that the film and roll do not stick together at the preheating temperature.
ところが、ゴムロールの場合、−船釣に、熱可塑性樹脂
フィルム及びゴムの両者は、電気伝導度が悪いため、フ
ィルムとゴムロールの表面が接触することにより、双方
に静電気が帯電し、その結果、種々の静電気障害が生じ
る。However, in the case of rubber rolls - for boat fishing, both the thermoplastic resin film and rubber have poor electrical conductivity, so when the surfaces of the film and rubber roll come into contact, both are charged with static electricity, and as a result, various Electrostatic damage will occur.
例えば、フィルム表面に帯電した場合は、フィルムの製

分が盛り上がり、その盛り上がりが製品の上巻きにまで
及ぶ。その結果、盛り上がり部分がシワとなって永久歪
となるため、例えば、ＯＨＰ用ポリエステルフィルムに
おいては、盛り上がり部分がスクリーン上に欠陥として
投影され、製品の品質を著しく損ねるという問題がある
。For example, if the film surface is charged, dirt and dust present during the film manufacturing process will adhere to the film surface. In polyester film for magnetic recording, if the magnetic recording layer is coated on the film with this dust attached, abnormally high protrusions will be formed in those areas, causing serious problems such as the inability to properly record and reproduce signals. causing quality problems. Furthermore, when a film with a very flat surface is rolled up, the dust-covered area bulges out, and the bulge extends to the top of the product. As a result, the raised portions become wrinkled and permanently deformed, so that, for example, in OHP polyester films, the raised portions are projected as defects on the screen, which significantly impairs the quality of the product.
一方、ゴムロールに帯電した場合は、それがゴムの絶縁
破壊電圧を超える場合には、ゴムロールの表面にひび割
れが突然入ったりすることがある。そして、この場合、
延伸ロールのように表面にせん断力が作用している場合
には、金属ロールの表層に巻かれたゴムが割れてゴム片
が飛び散り、付近の機械の摺動部に巻き込まれ、機械が
破損したり、フィルムが破断してロールに巻き付く等と
いった問題がある。On the other hand, if the rubber roll is charged and the electrical charge exceeds the dielectric breakdown voltage of the rubber, cracks may suddenly appear on the surface of the rubber roll. And in this case,
When shearing force is applied to the surface of a metal roll, such as on a stretching roll, the rubber wrapped around the surface layer of the metal roll will crack and pieces of rubber will fly off and get caught in the sliding parts of nearby machines, causing damage to the machine. There are also problems such as the film breaking and winding around the roll.
そこで、本発明は、ゴムロールにおける上記のような問
題に着目し、静電気障害のない熱可塑性樹脂フィルムの
加熱方法を提案するものである。Therefore, the present invention focuses on the above-mentioned problems with rubber rolls and proposes a method for heating a thermoplastic resin film that is free from static electricity damage.
すなわち、本発明の要旨は、未延伸あるいは少なくとも
一軸方向に配向された熱可塑性樹脂フィルムを複数の加
熱ロールを用いて、延伸又は熱処理温度まで加熱する方
法において、前記加熱ロールとして、金属ロール表面に
体積抵抗率が１０７Ω−以下であるゴムを被覆してなる
ゴムロールを用いることを特徴とする熱可塑性樹脂フィ
ルムの加熱方法に存する。That is, the gist of the present invention is to provide a method for heating an unstretched or at least uniaxially oriented thermoplastic resin film to a stretching or heat treatment temperature using a plurality of heating rolls. A method for heating a thermoplastic resin film, characterized by using a rubber roll coated with rubber having a volume resistivity of 10<7 >[Omega]- or less.
本発明で使用するゴムロールのゴム材質は、特に制限さ
れず、シリコン、クロロプレン、アクリル、エチレンプ
ロピレンタポリマー、フッ素、天然ゴム、タロロスルホ
ン化ポリエチレン等が使用し得るが、特に、シリコン系
、フッ素系ゴムを用いるのが好ましい。The rubber material of the rubber roll used in the present invention is not particularly limited, and silicone, chloroprene, acrylic, ethylene propylene tapolymers, fluorine, natural rubber, talolosulfonated polyethylene, etc. can be used, but in particular, silicone-based and fluorine-based rubbers can be used. It is preferable to use
本発明で使用するゴムロールは、体積抵抗率が１０７Ω
■以下であることが必要であり、通常、上記のゴム材質

適宜、導電性を付与する必要がある。導電性を付与する
手段としては、特に限定されないが、ゴム材質中に導電

って、例えば磁気テープ用ポリエステルフィルムの製造
においては、仮に、フィルムに付着したとしても信号の
記録に実害を及ぼさないように、極力小さな粒径のもの
を使用するのが好ましい。The rubber roll used in the present invention has a volume resistivity of 107Ω.
■It is necessary for the above-mentioned rubber material to satisfy the above-mentioned volume resistivity by itself, and therefore,
It is necessary to impart conductivity as appropriate. The means for imparting conductivity is not particularly limited, but it is preferable to knead conductive carbon, a metal component, etc. as a conductive agent into the rubber material. Since these additives are substances that have different properties from the rubber material, there is a possibility that they will come off from the roll surface. Therefore, for example, in the production of polyester films for magnetic tapes, it is preferable to use particles with as small a particle size as possible so that even if they adhere to the film, they will not cause any actual damage to signal recording.
本発明で使用するゴムロールのゴム被覆の厚みは、特に
限定されないが、余りにも薄い場合は、芯金の影響が表
面にまで及びゴムロール表面の硬度が高゛くなるので、
０，５關以上とするのが好ましい。また、ゴム硬度も、
特に限定されないが、硬度が低く表面が柔らか過ぎる場

生する恐れがあるので、５０度以上にするのが好ましい
。更に、摩擦係数も、特に限定されないが、延伸部や熱
処理部においては、延伸力やフィルムの収縮力によって
フィルムがロール上で滑らないように設定する必要があ
り、従って、フィルムがロール表面に粘着することのな
いようなゴム材質が選定される。The thickness of the rubber coating of the rubber roll used in the present invention is not particularly limited, but if it is too thin, the influence of the core metal will extend to the surface and the hardness of the rubber roll surface will become high.
It is preferable to set it to 0.5 degrees or more. In addition, the rubber hardness
Although not particularly limited, if the hardness is low and the surface is too soft, friction may occur due to plastic deformation when it comes into contact with the film, so it is preferably 50 degrees or more. Furthermore, the coefficient of friction is not particularly limited, but in the stretching section and heat treatment section, it must be set so that the film does not slip on the roll due to the stretching force or shrinkage force of the film, and therefore, the coefficient of friction must be set so that the film does not stick to the roll surface. A rubber material is selected that will not cause any damage.
そして、帯電現象は、条件によらず、フィルムとロール
が接することによって惹起されるものであるから、本発
明のゴムロールは、加熱ロールとして使用する場合のみ
ならず、加熱ロール自体が同時に延伸あるいは熱処理ロ
ールとして作用する場合にも有効に使用し得る。Since the charging phenomenon is caused by the contact between the film and the roll regardless of the conditions, the rubber roll of the present invention is useful not only when used as a heating roll, but also when the heating roll itself is stretched or heat-treated at the same time. It can also be effectively used when acting as a roll.
本発明の加熱方法は、代表的には、ポリエステルフィル
ムの延伸又は熱処理の際に使用されるが、他の熱可塑性
フィルムにおける同様の加熱にも適用し得ることは勿論
のことである。また、フィルムは未延伸又は延伸フィル
ムであってもよい。The heating method of the present invention is typically used during stretching or heat treatment of polyester films, but it goes without saying that it can also be applied to similar heating of other thermoplastic films. Further, the film may be an unstretched or stretched film.
以下、本発明を実施例により更に詳細に説明する。 Hereinafter, the present invention will be explained in more detail with reference to Examples.
