The utility model relates to an air duct in fiber spinning production lines, in particular to a telescopic air duct of a ring blowing device. The telescopic air duct is a sleeve surrounded by two layers of high temperature resistant woven fabrics, the cross section of the sleeve is in a rectangle, a plurality of rectangular steel wire rings 3 are installed between two layers of high temperature resistant woven fabrics as frameworks, the distance among rectangular steel wire rings is 2 to 6cm, the lower end of the telescopic air duct is fixed on the top end of a spinning corridor 2, and the upper end of the telescopic air duct is fixed on a ring blowing box body 1. The air duct in the fiber spinning production lines solves the problem of greater fiber group fracturing extending unevenness rate, uneven fiber group tension, and fiber group shaking, thereby fetching up the defects in existing technical structures.
