HEAT-DURABLE SPUN-LIKE FASCIATED YARN AND METHOD FOR PRODUCING THE SAME ABSTRACT OF THE DISCLOSURE A fasciated yarn, consisting of wholly aromatic polyamide fibers, which is excellent in mechanical properties, especially in creep durability in a high temperature atmosphere and is suitably utilized for industrial usage. The yarn can be produced by a method comprising the steps of: stretch-breaking a filament tow of the wholly aromatic polyamide fibers to form a staple fiber bundle and imparting a false-twist to the staple fiber bundle by a vortex while retaining parallelism of the staple fibers composing the bundle, thereby obtaining the fasciated yarn. 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°, and a number of wrap fiber groups in a range of from 0.5 to 20 per 1 cm in length of the yarn.
