Abstract (en)

An air spinning method comprising the steps of:- preparing at least one web of textile fibers (N1), to be fed by at least one introducer element (24) upstream of an air spinning device (28),- drawing said at least one web (N1) with at least one drawing device (32),- feeding said web (N1), previously drawn, in a spinning chamber (36) of the air spinning device (28),- spinning the fibers (12) inside the spinning chamber (36) by means of compressed air jets, so as to:- obtaining a yarn (4) comprising internal fibers (20) surrounded by external fibers (16),- wherein the yarn (4) has an overall thread count lower than Ne20 and wherein the total number of internal (20) and external (16) fibers is less than 200.
