ド系を用いるのが好ましい。For the surface layer, back layer, intermediate layer, etc. that are in contact with the tension body layer, it is recommended to use a material consisting of a polymer component of the same type as the resin or elastomer that is the polymer with which the liquid crystal polymer of the tension body layer is blended. preferable. For example, when a polyamide-based polymer is used as a compounding partner polymer for a liquid crystal polymer in a tension body layer, it is preferable to use a polyamide-based polymer also in the surface layer, back layer, intermediate layer, etc.
１一記構造を有するコンベアベル（・の製造方法として

（作用） 」二記構成を有する本発明は以下のように作用する。(effect) The present invention having the configuration described above operates as follows.

み合いがないので強度は低く、容５に割れてしまう。The rigid molecules of liquid crystal polymers are arranged in an orderly manner (｝0), so the viscosity is low and the fluidity is high, making it easy to form precisely, and when spun in this state, the molecules become oriented and crystallize. , a material with high elastic modulus and high strength can be obtained in the direction of orientation. However, since there is no entanglement between molecules in the direction perpendicular to the direction of orientation, the strength is low and it will crack into 5 pieces.

大負荷に耐えることができる。A liquid crystal polymer having the above characteristics and a thermal iiJ plastic resin or a thermal iiJ plastic elastomer are basically incompatible, but when a liquid crystal polymer is blended with a thermal iiJ plastic resin or a thermal iJ plastic elastomer and extruded, a liquid crystal polymer is formed. is oriented in the extrusion direction, yielding an anisotropic film with high tensile strength and elastic modulus in this direction. Therefore, a belt in which the alignment direction of the liquid crystal polymer blended with the resin or elastomer of the tension body layer coincides with the longitudinal direction of the conveyor belt can withstand large loads.
ストマーが配合されているので、液晶ポリマーの配四力
向に直角の方向にも所定の強度を有する。Since it contains a stromer, it also has a certain strength in the direction perpendicular to the alignment force direction of the liquid crystal polymer.

を設けても問題はない。In addition, since each of the surface layer, back layer, and intermediate layer in contact with the tension body layer is made of a polymer component of the same type as the resin or elastomer that is the compounding partner polymer of the liquid crystal polymer,
Adhesion treatment between each layer becomes unnecessary. Note that there is no problem even if an adhesive layer is provided between each layer.
