摘要： A monofilament of a thermoplastic resin having a high tenacity is produced by a process in which a monofilament is melt spun at a temperature of 220.degree. C. to 310.degree. C. from a thermoplastic resin through a nozzle having a cross-sectional area S (mm.sup.2) satisfying the following equations: ##EQU1## wherein I is a maximum cross-sectional secondary moment max (Ix, Iy) (i.e., the maximum secondary moment in the cross-sectional secondary moments with respect to the main x axis and y axis passing through the center of the gravity of the cross-section); and, then, is subjected to a multi-stage stretching under the conditions satisfying the following equations: ##EQU2## wherein i is a number of stretching stages, e is a base of natural logarithm (i.e., 2.71828), V.sub.1 is the first take-off linear velocity (m/min), V.sub.i+1 is the final take-off linear velocity (m/min) at the i-stretching stage, DR.sub.Ti is the total stretching ratio at the i-stretching stage, DR.sub.Tiw is the DR.sub.Ti from which the monofilament begins to become whitened at the i-stretching stage, T.sub.m is the melting point of the thermoplastic resin and .theta..sub.i is the temperature of the filament at the i-stretching stage.
