Abstract (en)
[origin: EP2730695A1] A spinning method using a whirling air spinning machine enables successful operation under high-speed spinning conditions with scum accumulation suppressed to a good extent. Spun yarns obtained with the spinning method are also provided. A fiber-processing agent having a kinetic viscosity at 30°C of 1 x 10 -6 to 100 x 10 -6 m 2 /s is mixed with compressed air in a whirling air spinning machine and is sprayed on fibers in said spinning method using the whirling air spinning machine, wherein the said fiber-processing agent comprises one, two or more of the following lubricant (A), the following lubricant (B) and the following lubricant (C). Lubricant (A) is an aliphatic ester compound of carbon number 5-70; Lubricant (B) is a linear polyorganosiloxane having a kinetic viscosity at 30°C of 5 x 10 -6 to 100 x 10 -6 m 2 /s; and Lubricant (C) is a mineral oil having a kinetic viscosity at 30°C of 5 x 10 -6 to 100 x 10 -6 m 2 /s.
