Fig. 1 is the front view of this utility model embodiment one;

Fig. 2 is the A-A sectional view of Fig. 1.

Detailed description of the invention

Now with specific embodiment, this utility model is further illustrated by reference to the accompanying drawings.

Embodiment:

With reference to figure 1 and Fig. 2, the present embodiment one discloses a kind of diaper, define described diaper and there is the transverse direction extended along waistline direction and the longitudinal direction extended to direction, back waist region by front waist region, it from top to bottom comprises successively: liquid permeability surface layer, opaque liquid bottom and be located at absorber between liquid permeability surface layer and opaque liquid bottom, wherein:

Described liquid permeability surface layer is made up of hydrophilic nonwoven fabrics 1 and the hydrophobic nonwoven 2 that is fixedly arranged on hydrophilic nonwoven fabrics both lateral sides respectively, the inner side of described two hydrophobic nonwoven 2 extends to form free margins along the mid portion to hydrophilic nonwoven fabrics 1, and described free margins is provided with the anti-leakproof elastic 8 leaked hunting;

The absorbent cores 5 that described absorber is wrapped up by upper strata hydrophilic nonwoven fabrics 3 and lower floor's loft non-woven cloth 4 forms, the both lateral sides of described lower floor loft non-woven cloth 4 is bonded together along the upper strata hydrophilic nonwoven fabrics 3 of both sides also finally and above absorbent cores 5 wrapping absorbent cores 5 respectively, and the thickness of described lower floor loft non-woven cloth 4 is 3 mm, the loft of described lower floor loft non-woven cloth 4 is 1.8, this lower floor's loft non-woven cloth 4 be arranged so that absorbent cores 5 forms solid space, compared to traditional material more water flowing breathe freely, flexibility is better, and wearing feeling is more comfortable, described upper strata hydrophilic nonwoven fabrics 3 by slightly water-wet non-woven fabrics31 and be located at slightly water-wet non-woven fabricsthe hydrophilic nonwoven fabrics 32 of 31 both sides forms, described in slightly water-wet non-woven fabrics 31 is the more weak non-woven fabrics of hydrophilic,the setting of this special construction can allow urine rapidly flow toward urine pants both sides, as long as the hydrophilic quality of hydrophilic nonwoven fabrics regulates the upper liquid measure controlling the hydrophilic oil preparation of hydrophilic nonwoven fabrics just can realize, the manufacturing process of this slightly water-wet non-woven fabrics is known technology, and this slightly water-wet non-woven fabrics also can directly commercially obtain, therefore, do not do herein and state in detailboth sides elongatedness (longitudinal direction) direction of described absorber is interval with the water conservancy diversion groove 51 of through absorber upper strata hydrophilic nonwoven fabrics 3 and absorbent cores 5, thus when urine flow is to urine pants both sides, by the solid space that loft non-woven cloth is formed, urine can rapidly by each water conservancy diversion groove water conservancy diversion to absorbent cores 5 bottom, each water conservancy diversion groove 51 is crisscross arranged along absorber length direction, the imbibition effect that can make absorbent cores of being crisscross arranged evenly, the cross section of described each water conservancy diversion groove 51 is arcuation, the bottom of each water conservancy diversion groove 51 extends to the middle part of absorber, thus make urine can flow to rapidly below in the middle part of absorber from absorbent cores both sides, the elongatedness direction, middle part of described absorbent cores 5 is interval with two rows and liquid can be led bottom absorbent cores 5 guiding gutter 52 on absorbent cores 5 top, described each guiding gutter 52 is crisscross arranged along absorber length direction, the cross section of each guiding gutter 52 is arcuation, the top of each guiding gutter 52 extends in the middle part of absorbent cores 5, bottom extends to absorbent cores both sides, the top of described each guiding gutter 52 does not penetrate absorbent cores 5 top layer, makes urine more difficult through absorbent cores top layer, effectively reaches the effect that anti-reflective is oozed, this Novel baby panty-shape diaper substantially increases the utilization rate of absorber, effectively can prevent reverse osmosis, improve the dry and comfortable effect of baby diaper, absorber each several part energy uniform pickup urine, imbibition diffusion length can reach absorptive core total length, can not produce hydrops phenomenon, and there will not be absorber lower part to be cut off by absorber top layer liquid cannot the phenomenon of absorbing fluid, double absorption is effective, has increased substantially the wet strength of absorber.

The top of described absorber is provided with guide layer non-woven fabrics 8, described guide layer non-woven fabrics 8 projected area in the horizontal direction overlaps with absorbent cores 5, guide layer non-woven fabrics is covered in above absorber completely, accelerate the diffusion velocity of liquid toward absorber both sides, described absorbent cores is made up of fine hair oar and Superabsorbent resin compound, described opaque liquid bottom is for breathing freely but fluid-tight PE counterdie 6, between the described hydrophobic nonwoven 2 and PE counterdie 6 of diaper both lateral sides, be respectively equipped with the lower limb extended along the longitudinal direction enclose elastic 9, the both lateral sides of described PE counterdie 6 back waist region is respectively provided with two waists and pastes 10, it can be fixed with mechanical press or the mode of supersonic thermal setting by PUR bonding, the front waist region of described PE counterdie 6 is provided with frontal waist plaster 7, the waist that diaper can be fixed on wearer when left and right waist pastes and is fixedly arranged on frontal waist plaster both lateral sides respectively prevents from coming off.

As long as based on the thickness of lower floor's loft non-woven cloth described in preceding solution 3 ~ 5 in the scope of mmthe loft of described lower floor loft non-woven cloth be 1.5 ~ 2.0 scope in all can realize this novel object, described water conservancy diversion groove 51 also can be substituted by the water conservancy diversion through hole of arcuation, and described guiding gutter 52 also can be substituted by the pod apertures of arcuation, can reach the object that this is novel equally.

Above, be only the embodiment utilizing this origination techniques content, the modification that any those skilled in the art use this creation to do, change, all belong to the scope of the claims that this creation is advocated, and be not limited to those disclosed embodiments.
