Disposable diaper with pearl granular interlayer

Abstract

The invention relates to the field of diaper products, in particular to a disposable diaper with a pearl particle interlayer. The paper diaper sequentially comprises a surface layer, a flow guide layer, an absorption core layer, a bottom film layer and a reverse osmosis layer from top to bottom. The front surface of the surface layer is provided with rhombic grid dimpled grains and rhombic convex particles, and the back surface of the surface layer is provided with rhombic grid convex grains and rhombic concave holes. The fabric weave of the reverse osmosis layer and the absorption core layer is warp velveteen weave, the warp velveteen weave comprises ground cloth and fluff fixedly connected to the ground cloth, and the fluff of the reverse osmosis layer is in contact with the fluff of the absorption core layer. The surface layer of the disposable diaper with the pearl granular interlayer can help urine to quickly diffuse on the surface of the surface layer and prevent the liquid from rising, so that the liquid is not prone to reverse osmosis. The fluff of the reverse osmosis layer and the fluff of the absorption core layer make contact to form a high-porosity water permeable channel, liquid is temporarily stored, the infiltration speed of the liquid is delayed, the liquid can be diffused in the transverse direction, and therefore the liquid can be rapidly and evenly diffused to the ground cloth of the absorption core layer, and gel blockage caused by conduction of the local liquid flow channel is avoided.

Description

technical field [0001] The invention relates to the field of diaper products, in particular to a paper diaper with a pearl granular interlayer. Background technique [0002] With the rapid development of the diaper market, consumers have higher and higher requirements for diapers. The requirements for diapers are good water absorption and air permeability, and at the same time, their softness is better, and they must have a soft feeling when they are close to the skin, and avoid contact with the skin. Contact causes itching or skin eczema. The main structure of the diaper includes a surface layer, a flow diversion layer, an absorbent core layer and a bottom film layer. At present, the surface layer and the flow diversion layer of diapers are generally made of flat hot-air non-woven fabrics, which have good water permeability, but the urine on the surface Poor diffusion in the plane of the layer, easy to cause local urine accumulation, and poor anti-rewet performance, urine ...

The main structure of the diaper includes a surface layer, a flow diversion layer, an absorbent core layer and a bottom film layer. At present, the surface layer and the flow diversion layer of diapers are generally made of flat hot-air non-woven fabrics, which have good water permeability, but the urine on the surface Poor diffusion in the plane of the layer, easy to cause local urine accumulation, and poor anti-rewet performance, urine is easy to seep back to the surface layer, resulting in skin eczema; the core layer is made of a mixture of super absorbent resin and fluff pulp, but the core layer It is easy to cause the local core layer to absorb water and solidify due to uneven urine diffusion, causing local lumps, affecting wearing comfort and use time. If the water-absorbing core layer is thickened to improve diffusivity, it will lead to fluffy and soft wearing Reduced degree; the girdle is prone to skin eczema due to poor air permeability and water absorption
