Abstract (en)
[origin: WO8703308A1] The fibrous material to be spun is placed as a sliver before the drafting equipment (2) and undergoes in the drafting equipment a pre-drawing and a main drawing. During its drawing, the sliver (10) is condensed to a minimum width equal to at least about 1,5 diameters of the twisting device. After being thus condensed, the sliver is no longer condensed until it is twisted, and its diameter is maintained while it is twisted. The width of the condenser (24) before the main drafting zone corresponds to at least about 1,5 diameters of the pneumatic twisting device (9). The latter has the same diameter in its injection section (3) as well as in its twisting section (4), from its inlet to its outlet. Soft and hairy yarn (11), similar to ring curled yarn, is thus obtained.
