Problems solved by technology

However, the traditional dust-free paper and fluff pulp are relatively fluffy and thick, which seriously affects the air permeability of absorbent products, making absorbent products thicker, especially when used in summer, it feels more stuffy, and may cause skin allergies, pan Symptoms such as redness and eczema
At the same time, the strength of non-woven fabrics and fluff pulp is low. After absorbing a large amount of body fluids, the absorbent core layer is prone to breakage and lumps. uncomfortable for the wearer

Abstract

The invention discloses a composite absorbent coil containing a foaming material, which comprises a surface foaming material layer, a superabsorbent resin layer, a fluff paste layer and a bottom surface layer. The surface foaming material layer is an open-cell foaming material, and the thickness is 1mm-5mm, and the hole opening rate is 70%-99.9%, Since the surface foaming material layer is an open-cell foaming material, the opening ratio is large, and the holes and the holes are connected to each other in the plane direction and the thickness direction, so that the body fluid can quickly absorb high water when reaching the open-cell foaming material. The resin layer penetrates and provides a large liquid storage space for the body fluid, thereby improving the penetration rate and liquid storage performance of the body fluid, and preventing leakage or leakage of body fluid due to slow absorption speed or insufficient liquid storage space. .

Description

technical field [0001] The invention relates to the technical field of hygienic absorbent products, in particular to a composite absorbent coil containing foaming materials. Background technique [0002] Disposable hygienic absorbent products, such as sanitary napkins, baby diapers, and adult diapers, are widely used in women, infants, middle-aged and elderly people who are prone to urinary incontinence, and patients with limited mobility due to their easy replacement. [0003] Absorbent products commonly present in the market are usually composed of a surface layer, an absorbent core layer and a breathable bottom film. The absorbent core layer is mostly composed of dust-free paper, fluff pulp, etc., with an appropriate amount of super absorbent resin added. When in use, the body fluid penetrates through the surface layer to the absorbent core layer, and the superabsorbent resin in the absorbent core layer will absorb the body fluid and lock the body fluid firmly to prevent...
