      (1) D (Denier, fiber size): refers to the fineness of the fiber. The larger the number of D, the thicker the diameter of the fiber. Usually, the fibers below 7D are fine, having a good texture; and the fibers above 15D are thicker, having strong elasticity (furniture and toy factories often use 7D and 15D fibers).

      (2) 28～64mm (fiber length): refers to the length of the fiber. 28～32mm is staple fiber, suitable for filling by machine; 51～76mm is filament fiber, which are good elasticity and suitable for using a loosening and filling combined machine to fill.
