## Abstract Nlon 6 fibers were zone drawn and zone annealed by using a continuous wave carbon dioxide laser to develop their mechanical properties. A laserโ€heating zone drawing was carried out under a applied tension of 35.4 MPa at a power density of 9.65 W ยท cm^โˆ’2^, and then the zoneโ€drawn fiber w
