One-off absorbing product

Abstract

The invention provides an one-off absorbing product. The one-off absorbing product comprises a hydrophilic surface material, an absorbing core layer, a bottom impervious material, and a multi-layer composite flow guide material which is located between the hydrophilic surface material and the absorbing core layer; the flow guide material comprises two layers of fiber meshes; the surface fiber mesh is prepared from skin-core double-component fibers which are regularly arranged along the length direction after being treated by a hydrophilic oily agent at a plurality of times; the surface fiber mesh is adhered and fixed through hot air; the lower fiber mesh is prepared from viscose acetal fibers and polyester fibers and is fixed by a spunlace entanglement manner; the lower fiber mesh has the characteristic of being loose in top and dense in bottom, namely, the upper surface is loose, and the lower surface is dense; the two layers of fiber meshes are adhered by spraying high-hygroscopicity hot melt adhesive; the composite flow guide material has the characteristics that liquid can permeate fast at a plurality of times and returns a little; the liquid is mainly dispersed along the length direction and is dispersed in a small area on the surface layer and in a large area on the lower layer; the dispersing area ratio of the lower layer material to the upper layer material is more than 15. The absorbing product has the characteristics of being dry and clean in surface, and comfortable to wear.

Description

technical field [0001] The present invention relates to a disposable absorbent article, in particular to a disposable absorbent article containing special flow-guiding material. Background technique [0002] Disposable absorbent articles generally include a hydrophilic topsheet material, a flow-inducing material, an absorbent core layer, and a water-impermeable backsheet material. For the user, the drier the surface layer in direct contact with human skin, the better. The diversion material is located in the middle of the surface layer and the absorbent core layer of disposable sanitary products (such as paper diapers, sanitary napkins, etc.) The layer is quickly and uniformly transferred to the water-absorbing core layer along the length direction, maximizing the absorption efficiency of SAP in the core layer, and effectively preventing the occurrence of liquid leakage of sanitary products. [0003] The composite guide layer used in the existing disposable sanitary produc...

AI Technical Summary

Problems solved by technology

The thickness of the composite diversion layer is relatively large, and the amount of cellulose fibers and superabsorbent fibers is relatively large, so the price is expensive, and the liquid cannot completely penetrate into the core, and there are still more parts remaining in the absorbent material of the diversion layer. Medium, resulting in a large amount of product rewet

In addition, this type of composite diversion layer is manufactured using dust-free paper technology (dry-laid papermaking technology), which will generate a lot of dust during the production process. inconvenient
