A thread, suitable for use as a sewing thread, and having increased tenacity and reduced thermal shrinkage properties. A multi-filament core yarn for the thread is formed from a preoriented yarn having a titre of 100 dtex-1,000 dtex which has been turned around an unheated pin of less than 10 mm diameter, heated to a temperature of 100.degree.-200.degree. C. for 0.01-10 seconds, and drawn with a drawing ratio equal to or greater than a normal drawing ratio. At least one effect yarn is intermingled with the core yarn to form a core-jacket thread having loops, not more than 15% of which are drawn tight in a knot-like manner.
