【発明の詳細な説明】
[産業上の利用分野コ
本発明はポリエステル組成物に関し、更に詳しくは微細
な析出粒子を含有し、帯電防止性を有するポリエステル
組成物に関する。DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a polyester composition, and more particularly to a polyester composition containing fine precipitated particles and having antistatic properties.
[従来の技術]
ポリエステル、とりわけポリエチレンテレフタレートの
二軸配向フィルムは機械特性、電気的特性、耐薬品性、
寸法安定性等の点で優れていることから、磁気テープ用
、コンデンサー用、包装用、製版用、電気絶縁用、写真
フィルム用等多くの分野で基材として用いられている。[Prior Art] Biaxially oriented films of polyester, especially polyethylene terephthalate, have excellent mechanical properties, electrical properties, chemical resistance,
Due to its excellent dimensional stability, it is used as a base material in many fields such as magnetic tape, capacitors, packaging, plate making, electrical insulation, and photographic film.
ポリエステルフィルムは各用途に応じ、その要求特性は
異なるが、普遍的に望まれる特性は滑り性のよいことで
ある。The properties required for polyester films vary depending on their use, but the universally desired property is good slipperiness.
滑り性をよくするためには、ポリエステル中に粒子を存
在させ、フィルム表面に凹凸を形成させればよいことが
よく知られている。この粒子には大きく2つの種類があ
る。一つは外部粒子と呼ばれるものであり、いま一つは
内部粒子(析出粒子)と呼ばれるものである。It is well known that in order to improve slipperiness, particles may be present in polyester to form irregularities on the surface of the film. There are two main types of these particles. One is called an external particle, and the other is an internal particle (precipitated particle).
内部粒子は、触媒として用いた金属化合物やリン化合物
等がポリエステル合成反応系で反応して析出してできた
粒子であり、ポリエステルとの親和性がよいという特長
をもっている。しかし、内部粒子は、金属種、リン化合
物の種類およびその量によって一元的に径が定まってし
まう欠点がある。The internal particles are particles formed by the reaction and precipitation of metal compounds, phosphorus compounds, etc. used as catalysts in the polyester synthesis reaction system, and have a characteristic of having good affinity with polyester. However, the internal particles have a drawback that the diameter is uniformly determined by the type of metal, the type of phosphorus compound, and the amount thereof.
それぞれの用途に応じて望まれるフィルムの表面凹凸の
度合は異なるが、いずれの用途においても、フィルムの
走行性、高品質化の要求が高まり、そのなめますます微
細な凹凸が要求されるようになっている。微細な凹凸の
要求は必然的に微細な粒子の必要を意味する。The desired degree of surface unevenness of the film differs depending on the application, but in all applications, there is an increasing demand for film runnability and high quality, and as a result, increasingly finer unevenness is required. It has become. The requirement for fine irregularities necessarily means the necessity for fine particles.
前記内部粒子は、ポリエステルとの親和性がよいという
特長を有しているため、微細化したものが得られればそ
の利用価値は極めて大きい。The internal particles have a good affinity with polyester, so if they can be made into fine particles, their utility value is extremely high.
従来は、カルシウム元素を含有する内部粒子(特公昭3
4−5144号公報)、リチウム元素を含有する内部粒
子(特開昭48−61556号公報)、リチウム元素、
カルシウム元素およびリン元素を含有する内部粒子(特
開昭51−112860号公報)等が知られているが、
さらに微細化された内部粒子が望まれている。Conventionally, internal particles containing calcium element (Tokuko Kosho 3)
4-5144), internal particles containing lithium element (JP-A-48-61556), lithium element,
Internal particles containing calcium element and phosphorus element (Japanese Unexamined Patent Publication No. 112860/1983) are known, but
Even finer internal particles are desired.
また、ポリエステルは、帯電しやすい欠点があり、さま
ざまなトラブルが起こる。例えばフィルムに加工した場

電撃、ゴミやほこりの吸引によるフィルム面の汚れ、印

起こり、また糸の場合にも、糸乱れ、毛羽立ちやもつれ
、また加工後着用時の密着、巻きつきによる不快感など
を生じる。このなめ、帯電防止性を有するポリエステル
が望まれていた。Polyester also has the disadvantage of being easily charged with electricity, which can cause various problems. For example, when processed into a film, problems such as wrapping around rolls during the film forming process, electric shock to workers, dirt on the film surface due to dust and dust absorption, printing defects, and clinging between films may occur. In the case of yarn, it also causes discomfort due to yarn disorder, fuzzing, tangles, and sticking and wrapping when worn after processing. For this reason, a polyester having antistatic properties has been desired.
[発明が解決しようとする課題]
本発明の目的は、上記従来技術の欠点を解消することに

An object of the present invention is to provide a polyester composition containing silky internal particles and having excellent antistatic performance.
