| abstract |
The invention relates to a yarn comprising a copolyamide in an amount of at least 90 wt% with respect to the total weight of the yarn, which copolyamide comprises 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, in which 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 and wherein the yarn has a tensile strength of at least 80 cN/tex as measured according to ASTM D885-04. The invention also relates to a process for preparing the yarn. |
