ORGAN Flat Shank Elastic S14BP 10 - O15X1SP14BP
15x1SP HAx1 SP: This is a special version of the 15x1 embroidery needle for stretch or elastic materials and tightly woven knits. It is made to higher standards, it has a snake's head shape due to a combination of a slightly bulged eye and a slightly reduced blade above the eye.
Ball Point: Ballpoint machine embroidery needles are designed to alleviate making holes in knit or loosely woven materials. The cross fibers which constitute the knit or loosely woven materials are relatively far apart as compared to those in tightly woven materials. When an embroidery needle with a standard "set" or "sharp" point encounters one of those fibers in penetrating the fabric, it cuts right through the fiber. This creates a hole in the fabric. The ball point needle pushes aside the fiber it encounters in penetration and thereby avoids making a damaging hole in the fabric. (It is also recommended to use the thinnest possible needle for a particular fabric)
