The present invention relates to a homogeneous filled multifilament yarn comprising UHMWPE having an intrinsic viscosity, a filler having a diameter of at most 20 [mu] m in an amount such that the ratio of the mass of the filler to the total mass of UHMWPE and filler is between 0.02 and 0.50, and wherein the intrinsic viscosity is at most 225 times the filler ratio, and wherein at least (i) the coefficient of variation in the linear density between the filaments of the yarn is at most 12%, (ii) the coefficient of variation in the toughness (TEN) between the filaments of the yarn is at most 12%, or (iii) the coefficient of variation in the toughness (TEN) of the multifilament yarn is at most 1.0%. The present application also relates to a method of manufacturing the yarn and an article comprising the yarn. 本发明涉及均匀的经填充的复丝纱线，其包含具有一定特性粘度的UHMWPE、直径为至多20μm的填料，所述填料的用量使得填料质量与UHMWPE和填料的总质量之比在0.02至0.50之间，并且其中所述特性粘度为填料比率的至多225倍，并且其中至少(i)所述纱线的长丝之间的线密度的变化系数为至多12％，(ii)所述纱线的长丝之间的韧度(ten)的变化系数为至多12％，或(iii)所述复丝纱线的韧度(TEN)的变化系数为
