본 발명은, 얀의 총 중량에 대해 90 중량% 이상의 양으로 코폴리아마이드를 포함하는 얀에 관한 것으로서, 이때 상기 코폴리아마이드는, a) 코폴리아마이드의 총 중량에 대해 95 중량% 이상의, 엡실론-카프로락탐으로부터 유도된 단량체 단위, 및 b1) 다이아민 X로부터 유도된 환형 단량체 단위, 및 이산 Y로부터 유도된 환형 단량체 단위, 및/또는 b2) 아미노산 Z로부터 유도된 환형 단량체 단위 를 포함하되, 이때 X, Y 및 Z로부터 유도된 단량체 단위의 총량은 코폴리아마이드의 총 중량에 대해 0.1 내지 4.5 중량%이고, 상기 얀은 ASTM D885-04에 따라 측정 시 80 cN/tex 이상의 인장 강도를 갖는다. 또한, 본 발명은 상기 얀의 제조 방법에 관한 것이다. 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 % with respect to the total weight of copolyamide, monomeric units derived from epsilon-caprolactam 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 % 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.
