Abstract: A yarn comprising a filament core and a staple fiber sheath, the staple fiber sheath comprises at least 95% by weight of a blend of first fibers and second fibers. The first fibers are natural cellulosic fibers and the second fibers are regenerated cellulosic fibers, wherein the weight ratio of the first fibers to the second fibers is in the range of 70/30 to 80/20, the weight ratio preferably being about 75/25; the average length of the fibers of the sheath is in the range of 10 to 25 mm, preferably 12 mm to 20 mm; the 5% (n) index of the fibers of the sheath is between 25 mm and 40 mm, more preferably in the range between 28 and 36 mm; the short fiber content SFC(n) of the sheath is between 30% and 70%; and the filament core comprises a plurality of polyester filaments.

Abstract: A yarn (1) having a core (2) and a sheath (3), preferably comprising staple fibers, said core comprising at least one polymeric core fiber (21), preferably a plurality of polymeric core fibers (21), wherein the amount of the core fibers (21) is at least 35% by weight of the total weight of the yarn (1) and said core (2) and said sheath (3) are spun together.

Abstract: A composite yarn (1) having a core (2) and a sheath (3), preferably comprising staple fibers (3a), said core (2) comprising at least one polymeric core fiber (21), preferably a plurality of core fibers (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.
