Yarns are formed of a copolyamide in an amount of at least 90 wt % with respect to the total weight of the yarn, wherein copolyamide includes (a) at least 95 wt % by weight with respect to the total weight of copolyamide, monomeric units derived from hexamethylene diamine and adipic acid and (b1) cyclic monomeric units derived from a diamine X, and cyclic monomeric units derived from a diacid Y, and/or b2) cyclic monomeric units derived from an amino acid Z. The summed amount of monomeric units derived from X, Y and Z is between 0.1 to 4.5 wt % by weight with respect to the total weight of the copolyamide. The yarns have a tensile strength of at least 80 cN/tex as measured according to ASTM D885-04.
