A polyamide filament used for an industrial fabric and available by mixing from 5 to 50 wt.% of a crystalline polyamide (A) obtained by the polycondensation reaction of metaxylcncdiamin and adipic acid and from 95 to 50 wt.% of another polyamide, characterized in that the polyamide filament does not undergo a reduction in thermal contraction stress in a cool-down region not greater than 80° C after heating (to 160 to 200 ° C) under a constant length condition (at initial load: 20 mg/d); and an industrial fabric using the filament. |
