Abstract (en)
A fasciated yarn, consisting of wholly aromatic polyamide fibers, with excellent mechanical properties, especially creep durability in a high temperature atmosphere, suitable for industrial uses. The fasciated yarn can be produced by a method comprising the steps of: stretch-breaking a filament tow (4) of the wholly aromatic polyamide fibers to form a staple fiber bundle (4 min ) and imparting a false-twist to the staple fiber bundle by a vortex (9) while retaining parallelism of the staple fibers composing the bundle. Structural characteristics of the yarn reside in a mean fiber length in the range of from 150 mm to 600 mm, a crimpability of less than 5%, a mean degree of parallelism of less than 3 DEG , and a number of wrap fiber groups in a range of from 0.5 to 20 per 1 cm in length of the yarn.
