There is provided a fibrillated continuous filament yarn comprised of random-length fibrils of a synthetic organic high polymer wherein: the average width/thickness ratio of cross sections of the fibrils (the "aspect ratio") is from about 2/1 to about 12/1, and the aspect ratios of the cross sections of the fibrils range from about 0.5/1 to about 20/1; the fibrils in the yarn exceeding 40 centimeters in length comprise at least 70 percent (by weight) of the yarn; the tenacity of the yarn is from about 0.1 to about 10 grams per denier; the total denier of the yarn is from 30 to about 10,000, and the average denier per fibril of the fibrils comprising the yarn is from about 0.5 to about 60; the elongation of the yarn is from about 0.5 to about 75 percent; and the initial modulus of the yarn is from about 2 to about 300. The yarn of this invention has high tenacity, a soft hand, and good cover.
