10mm<D _c <70mm

In Equation 1, D _c means the diameter (mm) of the polyethylene coil.

[Equation 2]

0.930 g/cm ³ <ρ _c < 0.945 g/cm ³

In Equation 2, ρ _c means the density of polyethylene (g/cm ³ ).

The fact that the three-dimensional random wound polyethylene coil pads 105 and 205 satisfy Equations 1 and 2 means that the diameter of the polyethylene coil embedded in the three-dimensional random wound polyethylene coil pads 105 and 205 is in the range of 10 mm to 70 mm. As a coil, the density is 0.930 g/cm ³ to It means a medium density polyethylene coil in the range of 0.945 g/cm ³ .

In general, foam-type pads that are built into mattresses and provide cushioning feel can provide adequate cushioning, but are heavy in weight, not easy to wash, and soft enough to not be able to be wound. not suitable However, the three-dimensional randomly wound polyethylene coil pads 105 and 205 according to the present invention are a yarn-type polyethylene coil having a diameter of 10 mm to 70 mm and a density of 0.930 g/cm ³ to By using a medium-density polyethylene coil within the range of 0.945 g/cm ³ to configure the coil pads 105 and 205 to have an appropriate thickness, for example, within a range of 3 to 5 cm, it is easy to wash at a light weight as well as provide a cushioning feeling. In addition, it can provide ductility enough to be wound, so it is suitable as a material for a ground bed because of its excellent handling and repeated use.

If the diameter (mm) of the polyethylene coil is less than 10mm, it is difficult to provide an appropriate cushioning feeling, and if it exceeds 70mm, it is not preferable because the rigidity is too strong and winding may not be possible.

In another example, the diameter (mm) of the polyethylene coil embedded in the three-dimensional randomly wound polyethylene coil pads 104 and 204 may be in the range of 20 mm to 60 mm or 30 mm to 50 mm.

If the density of the polyethylene coil does not reach 0.930 g/cm ³ , it may be difficult to maintain the shape of the bed or provide a cushioning feeling ^. If it exceeds, winding is impossible and it may be difficult for the user to feel a cushioning feeling, so it is not preferable. In another example, the density of the polyethylene coil embedded in the three-dimensional randomly wound polyethylene coil pads 104 and 204 may be in the range of 0.935 g/cm ³ to 0.940 g/cm ³ .
