Core spun yarn comprising short cellulosic staple fibers and process for its production

A method for producing a yarn comprising the steps of:

• A) selecting a filament core comprising a plurality of polyester filaments;
• B) selecting first fibers that are natural cellulosic fibers;
• C) selecting second fibers that are regenerated cellulosic fibers;
• D) providing a staple fiber sheath comprising at least 95% by weight of a blend of said first fibers and said second fibers, wherein a weight ratio of said first fibers to said second fibers is in a range of 70/30 to 80/20, the first and second fibers of the sheath have an average length between 10 and 25 mm, a 5% (n) index of the first and second fibers of the sheath is between 25 mm and 40 mm, and a short fiber content SFC(n) of the sheath is at between 30% and 70%;
• and
• E) combining said filament core and said staple fiber sheath, via ring spinning wherein an amount of the polyester filaments of the core is in a range of 10% to 30% of a weight of the yarn.
