Abstract
The invention discloses a disposable absorbing article, which comprises an absorbing main body and an outer enveloping material, wherein the absorbing main body comprises a liquid-permeable surface layer, a liquid-tight bottom layer and an absorbing layer between the liquid-permeable surface layer and the liquid-tight bottom layer, as well as protective wings which extend outwards from two sides of the disposable absorbing article, wherein a back gum layer is arranged on one side, close to clothing, of the liquid-tight bottom layer material of the absorbing main body, and the outer enveloping material, which is used for protecting the back gum layer temporarily, is arranged on one side, close to the clothing, of the back gum layer; the disposable absorbing article is characterized in that the liquid-permeable surface layer is a composite surface layer which is formed by splicing at least two sheets of materials in a longitudinal direction; and adjacent materials in the composite surface layer are partially overlapped in the longitudinal direction and are bonded in the overlapped region, so that the stepped composite surface layer is formed. The disposable absorbing article provided by the invention, by virtue of the stepped composite surface layer, is capable of rapidly transferring excrement of a wearer to a liquid transmission layer of the absorbing layer below; and since liquid is absorbed by the absorbing article, a back-infiltration amount is reduced and an integral diffusion effect is enhanced.
Description
Technical field
The present invention relates to disposable adsorption object, particularly relate to the disposable adsorption object having and improve surface material.
Background technology
In disposable adsorption object field, disposable absorbent articles and components comprises liquid permeability surface material, opaque liquid primer, and the absorbed layer between surface material and primer.Disposable absorbent articles and components for absorb and hold wearer as menses, urine and other Excretas.Absorbed layer is for collecting and store the Excreta of wearer.Absorbed layer generally includes by the fiber be separated, loose and the fibrous batt that forms of hydrophilic cellulose fiber of fluffing or fleece, and this absorbed layer can also comprise the microgranule of super absorbent polymer (SAP), granule, thin slice or fiber.After absorbing articles accepts wearer Excreta, even if the absorbed layer of liquid absorbate product absorbs and stores, but wearer still can feel the humidity of liquid, if these liquid continuously contact with wearer skin, then can stimulate human body skin.
A problem of disposable adsorption object is the absorbing articles surface dryness it problem of contact skin.In general, the surface of contact skin is drier, and absorbing articles just makes people feel more comfortable.In order to seek the diffusion of disposable adsorption object, usually one deck transfer layer of liquid is set between surface material and absorbed layer material.In addition, attempted reducing surperficial moist degree to improve comfort level in disposable adsorption object.Be in the Chinese patent of CN1476337A at publication number, disclose the diaper structure being provided with three-dimensionally shaped porose thermoplastic film between surface layer and absorbed layer, porose thermoplastic film is having large space towards that face of absorbed layer, and the program can effectively prevent bleeding back of liquid.But the speed that Excreta transfers to absorbed layer is fast not, and wearer still feels that surface layer is moistening, uncomfortable, and does not have covering effect to slop.
In addition, disposable adsorption object is if sanltary towel is when absorbing the menses of women's wearer excretion, liquid on whole absorbing articles is easy in sight, and particularly on surface material, large-area menses bloodstain allows people feel unpleasant, and this is that client is unsatisfied with part.Be in the Chinese patent of CN1646073A at publication number, disclose a kind of absorbent item, it comprises multi-part liquid absorbing structure, this multi-part liquid absorbing structure comprises first liquid absorption piece and second liquid absorption piece from top to bottom. first liquid absorption piece is the flexible fiber matrix comprising multilayered fibrous material layer of bonding, second liquid absorption piece can from comprise composite construction, cellulose fluff structures, be generally uniform air-laid structures hydrogel structure select.The interstitial spaces formation of first liquid absorption piece at lower surface place makes liquid transmit along the length direction of first liquid absorption piece.But the area of first liquid absorption piece is less than 2/7 of second liquid absorption piece area in the program, therefore menses can not be diffused rapidly in second liquid absorption piece.In addition, first liquid absorption piece is the fibrous layer flexible fiber matrix of multilamellar, and its lateral dimension is relatively large, and lateral stiffness is large, allows wearer feel uncomfortable, and does not have covering effect to slop.
Summary of the invention
The object of the invention is to provide a kind of disposable adsorption object improved transfer layer of liquid, and this absorbing articles has the improvement surface material that wearer Excreta can be quickly transferred to absorbed layer.
A kind of disposable adsorption object provided by the invention, comprise and absorb main body and peplos material, absorb main body and there is liquid permeability surface layer, opaque liquid bottom and the absorbed layer be positioned between the two, from the outward extending flap of disposable adsorption object dual-side, the close clothes side of the liquid-tight primer absorbing main body is provided with gum layer, be provided with the little coated fertilizer of gum layer temporary protection at gum layer near clothes side, described liquid permeability surface layer is the composite cover that at least two sheet material are spliced at longitudinal direction, adjacent materials in composite cover partly overlaps at longitudinal direction, and the composite cover of stairstepping is formed in the bonding of this overlapping region.
According to disposable adsorption object provided by the invention, the stairstepping difference in height in a thickness direction of described composite cover is 0.2-5.0mm.The stairstepping difference in height in a thickness direction of described composite cover is preferably 1-3mm.The length of adjacent materials in longitudinal direction overlapping region of described composite cover is 2-50mm.The upper layer of material that described composite cover is positioned at overlapping region is straight line or wave, gear line in the shape of an end margin of overlapping region.The overlapping region of composite cover adjacent materials be positioned at flap region in the middle part of longitudinal direction and neighbouring position thereof.Described composite cover is that 2 sheet material are spliced, and stitching position is positioned at the insult area of towel body.Described composite cover is more than 3 materials compositions, more than 3 materials from towel body front end to the back-end direction form the stepped surface layer by rank increasing or decreasing.Described composite cover is more than 3 materials compositions, stepped surface layer from flap region to towel body front end, rear extreme direction forms the stepped surface layer of ladder increasing or decreasing.
According to disposable adsorption object provided by the invention, adopt stair-stepping composite cover to have the transfer layer of liquid that wearer Excreta can be quickly transferred to absorbed layer below, after absorbing articles absorbing fluid, the amount of bleeding back is little, and overall diffusion effect is good.
