(57) [Summary] [PROBLEMS] To improve peach skin tone without giving a fluffy feeling when knitted and woven fabrics are excellent in productivity and quality stability, fuzz is expressed by performing alkali weight reduction treatment later. Provided are a method for producing a latent fluff composite textured yarn capable of imparting a texture and a dry feeling, and a knitted fabric obtained by using the textured yarn. An R-SO 3 M (R: alkyl group or an aryl group having 7 to 40 carbon atoms of 3 to 30 carbon atoms, M: alkali metal) organic sulfonic acid metal salt 0.1-10 wt% content of And the birefringence index Δn A is 0.020 to 0.060. Polyester highly oriented undrawn filament (A), and Birefringence Δn B is −0.025 ≦ (Δn A −Δn B ) ≦ A fluid nozzle (3) is applied to the polyester highly oriented unstretched filament (B) which satisfies 0.015 to perform a fluid disturbance treatment, and a loop is formed on both filaments (A, B). Simultaneous stretching false twisting is performed by the heater (5) and the false twisting device (7) under conditions that do not disappear. |
