The invention relates to an air-jet vortex spinning slot type hollow ingot. The air-jet vortex spinning slot type hollow ingot comprises a resultant yarn channel (1), 2-3 rows of wall face inclined through holes (2) and wall face grooves (3). Resultant yarn is conveyed out of the hollow ingot along the resultant yarn channel after being formed by weaving fibers, and then winding is finished; the number of each row of inclined through holes is 6-10. According to the air-jet vortex spinning slot type hollow ingot, friction coefficients of the wall face of the hollow ingot are increased by notching treatment on the wall face, the inclined through holes in the wall face of the hollow ingot can improve positive pressure between the fibers and the wall face, thus, the twisting effect achieved in the process of rotating of the fibers can be enhanced, capacity of cohesion among the fibers is improved, and therefore breaking strength of the yarn is improved.
