PROBLEM TO BE SOLVED: To provide a fiber reinforced layer for a conveyor belt, capable of improving appearance quality and productivity while including polyester fibers as weft.SOLUTION: Warp 2 and weft 3 of a fiber reinforced layer 1 embedded in a conveyor belt 6 are formed from polyester fibers. The weft 3 is a single twisted yarn obtained by unidirectionally twisting a filament yarn 3a or a plurality of filament yarns 3a in parallel. The number of twists T (times/10 cm) is set to 8-10 when the fineness D per weft 3 is 840 dtex or greater and less than 2200 dtex, the number of twists T is set to 7-8 when the fineness D is 2200 dtex or greater and less than 4400 dtex, and the number of twists T is set to 6-7 when the fineness D is 4400 dtex or greater and less than 6700 dtex. |
