Problems solved by technology

Its disadvantages: Since the middle absorbent layer is perforated longitudinally, it is impossible to cover the polymer resin, and the bottom layer needs to be specially covered, and it is impossible to realize the production and cutting of large-area composite non-woven fabric cores
Its shortcomings: First, because the polymer resin cannot be uniformly combined with the bulky non-woven fabric, the resulting polymer composite core absorbs the uneven surface formed after absorbing the liquid, which makes the user feel uncomfortable; It is because the bulky non-woven fabric is used to fix the base material of the polymer resin, which is not only thick, but also cannot effectively position the polymer resin

Embodiment 1

[0011] Example 1: Refer to the attached figure 1 . A semi-packed ultra-thin liquid-absorbent core body, comprising a covering layer 4 on which is provided with one or more layers of puffed non-woven fabric and polymer water-absorbing resin distributed on the puffed non-woven fabric The liquid-absorbing layers 1 and 2 are superimposed, the covering layer 3 is located on the liquid-absorbing layer, and the covering layer 4 is folded on the edge of the covering layer 3 to form a half-packed ultra-thin liquid-absorbing core, which is thermally pressed or ultrasonically welded. The thickness of SAP applied to each layer of puffed non-woven fabric surface depends on the size of liquid absorption.

[0012] The half-pack of ultra-thin liquid absorbent cores distributed in the composite non-woven fabric are distributed in spacing strips and the spacing part is the bonding and cutting part. The bonding method can be ultrasonic bonding, electric heating fusion bonding, and glue bonding .

Embodiment 2

[0013] Example 2: On the basis of Example 1, refer to the attached figure 2 . The cover layer 3 or the cover layer 4 is provided with a guide layer 5, the purpose of which is to accelerate the diffusion and absorption of the liquid. The cover layer 4 is closed on the side of the guide layer 5 to form a half-packed ultra-thin suction Liquid core body.

Embodiment 3

[0014] Example 3: On the basis of Example 1 or 2, there is a small amount of glue on the polymer water-absorbing resin layer between the multilayer puffed non-woven fabrics.

Abstract

The invention relates to a half-wrapped ultrathin liquid-absorption core body and a making method. The half-wrapped ultrathin liquid-absorption core body can enable macromolecule resin to be distributed among swelling non-woven fabric grains and enable the liquid-absorption property of the macromolecule resin to be completely exerted and can effectively decrease the thickness of an absorber itself on the premise that a fluff pulp carrier is not needed for positioning the macromolecule resin, and an adhesive is not needed for positioning the macromolecule resin. The half-wrapped ultrathin liquid-absorption core body comprises a wrapping layer, a liquid-absorption layer is located on the wrapping layer, a covering layer is located on the liquid-absorption layer, a diversion layer is located on the covering layer, and the edges of the wrapping layer are taken up on the edges of the diversion layer. The half-wrapped ultrathin liquid-absorption core body and the making method have the advantages that a fluff pulp does not need to serve as a fixation base material of the macromolecule resin, the thickness of the absorber is greatly decreased, and the problem that distribution of the macromolecule resin on the fluff pulp is uneven is solved; due to the fact that the adhesive is not needed for fixing the macromolecule resin, the absorbing capacity of the macromolecule resin is fully utilized; the manufacturing cost is greatly reduced, and the production efficiency is greatly improved.

Description

Technical field [0001] The invention relates to a polymer resin that can be uniformly distributed between the textures of a puffed non-woven fabric without the need for a fluff pulp carrier or an adhesive to position the polymer resin. The semi-packed ultra-thin liquid absorbing core body which can fully exert the liquid absorption performance of the resin and can effectively reduce the thickness of the absorber itself and the manufacturing method thereof belong to the field of manufacturing absorbent bodies for sanitary products. Background technique [0002] CN 104367418A, the name "a composite absorbent core", includes a surface layer, a bottom layer, and an intermediate absorbent layer arranged between the surface layer and the bottom layer. The intermediate absorbent layer is provided with a plurality of longitudinal perforations. The longitudinal perforations are filled with polymer water-absorbing resin. Its shortcomings: Since the middle absorbent layer is longitudinally...
