Abstract (en)
[origin: CN105316811A] The invention relates to a method for producing an air spun yarn (10). Two adjacent fibre bundles (4, 4') are drafted by virtue of a drafting device (5), and are then transmitted to a pneumatic twisting mechanism (6) and are drawn out from the twisting mechanism (6) in the form of yarn (10), and the yarn (10) is thereafter wound on a cross winding bobbin (11). According to the method, an air-flowing type true-twisting spinning mechanism having a drafting stop device is used as the twisting mechanism (6), and the two conveyed fibre bundles (4, 4') are differentiated from each other in at least one characteristic aspect, wherein the first fibre bundle (4, 4') is conveyed closer to a longitudinal axis of the twisting mechanism (6) than the second fibre bundle (4, 4').
