transporting the microtextured yarn in an untensioned state to a heat treatment unit.
11. The process of claim 10, further comprising crimping the yarns before transporting the yarns to the heat treatment unit.
12. The process of claim 10, further comprising delivering the yarn in its untensioned state to an intermediate device before transporting the yarn to the heat treatment unit.
13. The process of claim 11, wherein the yarn is crimped after the yarn has been microtextured.
14. The process of claim 10, wherein the step of microtexturing the yarn comprises forming loops or twists in the filaments of the yarn using a texturing air nozzle.
