1. A composite yarn (1) having a core (2) and a sheath (3), said sheath comprising staple fibers (3a) said core (2) comprising at least one polymeric core fiber (21), made of polymeric material,
wherein the total amount of the core fibers (21) is at least 35% by weight of the total weight of the composite yarn (1), and
wherein the core fiber (21) and the sheath (3) are spun together,
wherein the core fibers (21) have a linear density of 14 denier or less,
wherein the core fibers (21) are non-elastomeric filaments and the core comprises at least 12 core fibers,
said core (2) further comprising a plurality of elastomeric filaments (22), the core fibers (21) and the plurality of elastomeric filaments (22) being connected together in a continuous way such that the core fibers and the plurality of elastomeric filaments are attached at a plurality of points, and
wherein the core fibers are Drawn Textured Yarns (DTY) and the core fibers (21) and the elastomeric filaments (22) are intertwined such that the elastomeric filaments (22) are coiled about the core fibers (21).
