the utility model provides a cotton air core of bubble, including the intermediate level, the intermediate level is formed by a plurality of bubble cavitys permutation and combination, the upper and lower both sides in intermediate level are bonded respectively and are had upper strata and lower floor, the upper strata with between the intermediate level the lower floor with all be equipped with the macromolecule layer that absorbs water between the intermediate level.

Preferably, the bubble-like cavity is a hemispherical structure.

Preferably, a plurality of the bubble cavities are of one-piece moulded construction.

Preferably the diameter of the bubble is 2-4mm and the thickness is 1-2mm.

Preferably, the upper layer is made of hot air non-woven fabric, and the thickness of the hot air non-woven fabric is 0.1-0.5mm.

Preferably, the lower layer is made of dust-free paper, and the thickness of the dust-free paper is 0.1-0.5mm.

Preferably, the water-absorbing polymer layer is made of water-absorbing polymer resin, and the thickness of the water-absorbing polymer layer is 0.5-1mm.

The utility model discloses for prior art gain following beneficial technological effect:

the utility model provides a foam air core, which comprises a middle layer, wherein the middle layer is formed by arranging and combining a plurality of bubble cavities, the upper side and the lower side of the middle layer are respectively adhered with an upper layer and a lower layer, and water-absorbing polymer layers are respectively arranged between the upper layer and the middle layer and between the lower layer and the middle layer; through setting up the intermediate level of constituteing by a plurality of bubble cavitys, bubble cavity makes the inside air bubble that forms of cotton core to increased the air permeability and the elasticity of cotton core, improved the comfort level greatly, the setting on water-absorbing polymer layer can improve the absorption effect.
