Summary:PROBLEM TO BE SOLVED: To provide an air-spinning nozzle conforming to the speed up of its spinning speed of a thin yarn-spinning in an air-spinning device. SOLUTION: This air-spinning nozzle 5 by arranging a first nozzle N1 and second nozzle N2 at the downstream side of a draft roller is provided by setting the cross-sectional areal ratio of the inner diameter D1at the fiber-introducing passage part to the inner diameter D2of the air-jetting out part in the second nozzle as a relationship of [(D2/2)2π]/[(D1/2)2π]≥3, i. e., the ratio of the inner diameters D1to D2as D2/D1≥1.73 (provided that 0.7≤D1and D2≤2.1 (unit: mm)).
