Abstract
A yarn with the appearance of a spun yarn, made from polyamide-based filaments. The yarn has crimped bulked parts, and parts which are both tight and interlaced, has a cohesion factor lying between 90 and 140 knots/meter, a Young's modulus lying between 100 and 150 cN/tex, and a difference in orientation between the two populations of filaments, evaluated by measurement of the sonic modulus, lying between 25 and 50 cN/tex. The textile articles obtained from this yarn simultaneously have a soft feel, bulk and strength.
