Description
Technical field
The present invention relates to a kind of disposable adsorption object, especially relate to a kind of disposable adsorption object that improves absorbent core structures that has.
Background technology
Disposable adsorption objects such as existing baby paper diaper, adult-incontinence person articles for use are well-known.This kind disposable absorbing articles major part all has similar structure: permeable top layer, opaque liquid bottom, and the absorbent cores between permeable top layer and the opaque liquid bottom.This absorbent cores can receive and receiving fluids, like slop.Absorbent cores is become by the mixed core system of hydrophilic fibre net parcel fluff pulp fibers and super absorbent polymer usually.Permeable top layer is used for comfortable and dry and comfortable sensation is provided with Body contact the time, allows liquid freely to pass through simultaneously, the absorbent cores below getting into.The opaque liquid bottom is used for the liquid that is absorbed is retained in absorbent cores, thus the clothes of the dirty wearer of liquid that prevents to be absorbed.
, temporarily be kept in the fluff pulp fibers through behind the top layer like the body fluid of urine, absorbed by super absorbent polymer then and super absorbent polymer holds and expands, the fluid preservation that is absorbed is lived, super absorbent polymer can increase the absorptive capacity of absorbent cores.Increasing super absorbent polymer when improving the water absorbability of absorbing articles, thereby or when reducing absorbent cores and reducing the thickness of absorbing articles, just should reduce the amount of bulky fluff pulp fibers.In the case, the fluff pulp fibers in the absorbent cores and the ratio of super absorbent polymer just reduce relatively, and the commissure between the fluff pulp fibers also reduces.Consequently; Disposable adsorption object is after repeatedly absorbing urine or menses; The volume of super absorbent polymer increases because absorb liquid greatly; Absorbent cores is agglomerating and tomography situation take place at other positions along with local accumulation can appear in the motion of wearer under the effect of pressure or shearing force, has not only influenced the effect that absorbs liquid, also influences wearing comfortableness.
At publication number is in the patent of CN2323768Y; A kind of embossing sanitary towel is disclosed;, the periphery of suction inner core is except that, heat-sealing embossing bonding with PUR are fixed on the leakproof counterdie, and the centre of suction inner core also has embossing to be pressed on the leakproof counterdie in order to the inner core that will absorb water; This utility model in use can the group of rising, wrinkling like this, and the towel body remains smooth, next to the shin.At publication number is in the patent of CN2511273Y, discloses a kind of resistance to deformation, anti-fracture sanitary towel, in the middle of absorbent material layer or between absorbent material layer and the opaque liquid bottom, one deck wet-strength paper is set.At publication number is in the patent of CN1185937A; A kind of absorbing articles is disclosed; It comprises a kind of liquid-keeping absorber; This absorber comprises a kind of fiber or thin slice that is different from the absorbent paper pulp fibres, this fiber or thin slice when contacting with water between they itself or and other components between produce viscosity, the shape of stable absorption body thus.But above-mentioned measure can damage the quality of absorber, makes absorber become really up to the mark, nor can fine conglomeration, the breakage problem that improves in the absorber use.
Summary of the invention
Main purpose of the present invention is to overcome the shortcoming of prior art, provides a kind of absorbent cores local accumulation of improving agglomerating and the disposable adsorption object of fracture or tomography situation takes place for other positions.
According to a kind of disposable adsorption object provided by the invention; Has the absorbent cores between permeable top layer, opaque liquid bottom, permeable top layer and the opaque liquid bottom; Said absorbent cores is the mixing core body of hydrophilic fibre net at upper and lower both sides parcel fluff pulp fibers and super absorbent polymer; The mixing core body that it is characterized in that said fluff pulp fibers and super absorbent polymer is provided with elongated discontinuous district; In discontinuous district, do not have fluff pulp fibers and super absorbent polymer, the hydrophilic fibre net that mixes the upper and lower both sides of core body is bonded with each other together in the discontinuous district of mixing core body.The hydrophilic fibre net of the upper and lower both sides of said mixing core body is bonded with each other through a kind of mode in ultrasound wave, heat bonding or the PUR in discontinuous district.
According to disposable adsorption object provided by the invention, 2-16 discontinuous district can be set in said mixing core body, each discontinuous district is in horizontal and/or longitudinal separation setting.In a specific embodiment, the discontinuous district of mixing in the core body can be arranged in the 2-4 group in the vertical, and each organizes discontinuous district has 1-4 discontinuous district that is provided with at interval in the horizontal in the horizontal.Position in the horizontal, discontinuous district of each group is corresponding or respectively organize discontinuous district and be arranged alternately at interval in the horizontal with the discontinuous district of other groups in the horizontal.The hydrophilic fibre net that mixes the upper and lower both sides of core body is bonded with each other in discontinuous district.
According to disposable adsorption object provided by the invention; Mixing core body through fluff pulp fibers and super absorbent polymer is provided with discontinuous district, and the hydrophilic fibre net that mixes the upper and lower both sides of core body is bonded with each other together through modes such as PUR, ultrasound wave, heat bondings in the discontinuous district of mixing core body.The hydrophilic fibre net that mixes the upper and lower both sides of core body is bonded with each other through point or line juncture in discontinuous district.It is agglomerating and fracture or tomography situation take place at other positions to occur local accumulation after can preventing to expand after the super absorbent polymer absorbing bodily Excreta in the absorbent cores, effectively improves the integrity of absorbent cores.
