Problems solved by technology

However, in this solution, the area of ​​the first liquid-absorbing member is less than 2 / 7 of the area of ​​the second liquid-absorbing member, so menstrual blood cannot be quickly diffused into the second liquid-absorbing member
In addition, the first liquid-absorbent component is a multilayer fibrous layer flexible fibrous matrix with relatively large lateral dimensions and high lateral stiffness, which makes the wearer feel uncomfortable and has no covering effect on human excretions

Embodiment 1

[0024] like Figure 1-Figure 2As shown, a disposable absorbent article comprises a liquid-permeable top sheet material 2, a liquid-impermeable back sheet material 5 and an absorbent structure located between the liquid-permeable top sheet material 2 and the liquid-impermeable back sheet material 5, the absorbent structure Consisting of several parts, the absorbent structure comprises a liquid transfer layer 3 and an absorbent layer 4 from top to bottom. The disposable absorbent article may further comprise an adhesive material 8 on the backsheet material 5 for attaching the disposable absorbent article to the wearer's clothing, and a release layer 9 covering the adhesive material 8 . The width of the liquid transfer layer 3 is 70%-100% of the width of the absorbent layer 4, preferably 90%-100%, most preferably 100%. When the width of the liquid transmission layer 3 is the same as that of the absorbent layer 4, menstrual blood and the like can be transmitted and diffused in th...

Embodiment 2

[0041] like Figure 6-7 As shown, a layer of perforated thermoplastic film 39 is disposed between the liquid transfer layer 3 and the absorbent layer 4 of the multilayer structure, and the liquid transfer layer and the perforated thermoplastic film of the multilayer structure have a fluid passage in communication. The apertured thermoplastic film 39 can be bonded to the side of the liquid transfer layer 3 of the multi-layer structure near the absorbent layer 4 by an adhesive, and serves as a layer in the multi-layer structure of the liquid transfer layer 3 of the multi-layer structure. Apertured thermoplastic film 39 may also serve as a separate layer between the liquid transfer layer and the absorbent layer. The apertured thermoplastic film may preferably be a three-dimensional apertured thermoplastic film.

[0042] Sample 4 and comparative sample were prepared respectively, the comparative sample was an ordinary sanitary napkin available on the market, the liquid transfer l...

Abstract

The invention discloses a disposable adsorption object comprising permeability surface course material (2), liquid-tight ground floor material (5) and adsorption structure between the permeability surface course material (2) and the liquid-tight ground floor material (5), wherein the adsorption structure comprises a plurality of parts and comprises a liquid transport layer and an adsorption layer from top to bottom; the liquid transport layer is provided with a multiple-layer structure; the liquid transport layer is formed by coherent air lay length-grade fiber, air lay cellulose villus fiber, air lay chemical modified cellulose fiber, hydrogel fiber or the composite of the above fibers; the liquid transfer layer can comprise a liquid obtaining layer, a temporary liquid storage layer and a liquid distribution layer from top to bottom; and the liquid transfer layer is provided with cutting lines which are arranged at interval in the width direction and extend lengthways. The adsorption object has the advantages that the adsorption object can cover human body excretions and is comfortable to wear.

Description

technical field [0001] The present invention relates to disposable absorbent articles, and more particularly to disposable absorbent articles having improved transmission layer properties. Background technique [0002] In the field of disposable absorbent articles, disposable absorbent articles generally comprise a liquid-permeable topsheet material, a liquid-impervious backsheet material, and an absorbent layer positioned between the topsheet material and the backsheet material. Disposable absorbent articles are generally used to absorb and contain the wearer's excrement such as menstrual blood, urine and other excrement. The absorbent layer is used to collect and store the wearer's excrement. The absorbent layer generally comprises a fibrous batt or web of separated fibers, loose and fluffed hydrophilic cellulose fibers. The absorbent layer may also comprise microparticles, granules, flakes or fiber. After the absorbent article receives the excrement of the wearer, even ...
