Abstract
A textured yarn composed of continuous filaments having a crimp with marked cusps, the molecular structure of the continuous filaments in the cusps being different from the molecular structure of the portions of the continuous filaments between consecutive cusps. A process for manufacturing the above-described textured yarn including knitting a yarn composed of drawable continuous thermoplastic filaments to form a knitted fabric, drawing the knitted fabric with a force close to but at the maximum equal to the maximum drawing force that the drawable yarn could withstand without breaking the filaments and deknitting the drawn knitted fabric.
