さらに高圧の圧縮空気を供給できる設備が必要になる。In the above embodiment, the pressure of the compressed air for the yarn suction operation is 5 kg / cm 2 using the conventional yarn forming device.
In addition, the spinning speed could be set to 300 m / min by setting the pressure of compressed air for the yarn forming operation to 8 kg / cm 2 , but the discharge pressure of the compressor installed in a general factory is 7 to 8 kg / cm 2 is the limit, it is necessary equipment can be further supplied to the high pressure of the compressed air for speed.

である。Therefore, the small diameter portion 33b of the nozzle 33 is formed.
The relationship between the cross-sectional area ratio of the total cross-sectional area of the opening of the compressed air injecting fine hole 33h and the suction amount, and the twisting ability corresponding to the spinning speed was examined as shown in FIG.
We were able to obtain the results shown in. The injection hole 33h of the nozzle 33 used at this time has an inclination angle (θ) of 65 °, and the pressure of the compressed air supplied to the nozzle 33 is 5 kg / cm 2

It intersects with the reference line (A), and when the cross-sectional area ratio is 100%, it falls below the minimum reference line (B) of the suction amount that can be spun. Also,
It can be seen that the twisting ability improves as the cross-sectional area ratio increases.

When the compressed spun yarn is spun and then the compressed air supply path is switched to supply compressed air for the yarn forming operation with a pressure of 5 kg / cm 2 or more, the minimum reference line of the suction amount that can be spun 8 in the conventional nozzle 33 without going under (B)
It is possible to obtain a twisting ability that is substantially the same as the twisting ability obtained by supplying compressed air of Kg / cm 2 or more, and in the case of the nozzle 33 having a cross-sectional area ratio of 100%, a yarn suction operation is performed. By setting the pressure of the compressed air to 2.5 kg / cm 2 and the pressure of the compressed air for the yarn forming operation to 3.5, it is possible to obtain substantially the same twisting ability.
