Abstract
The invention relates to a water absorbing core body for a hygiene product and a production process for the water absorbing core body. The water absorbing core body comprises an upper flow guide layer and a lower water absorbing layer, wherein the flow guide layer and the water absorbing layer are matched concavo-convex surface structures; the flow guide layer consists of first concave surfaces and first convex surfaces, which are alternately arranged; the water absorbing layer consists of second concave surfaces and second convex surfaces, which are alternately arranged; adhesive layers are arranged on the first convex surfaces respectively; macromolecular water absorbing particles are arranged in the second concave surfaces; the flow guide layer is adhered to the water absorbing layer through the adhesive layers. According to the water absorbing core body and the production process, the macromolecular water absorbing particles completely do not contact with an adhesive, so that the macromolecular water absorbing particles can be fully utilized without waste, and high absorption performance is achieved; in addition, with adoption of the concavo-convex surface structures, multiple grooves can be formed, so that a good flow guide function can be realized without leakage; moreover, by the concavo-convex surface structures, the contact surface of the water absorbing core body and skin can be reduced, irritation to the skin can be reduced, and higher safety is ensured.
Description
Technical field
The present invention relates to a kind of hygienic article, especially relate to a kind of hygienic article Water-absorption core body and production technology thereof.
Background technology
Water-absorption core body of many uses, at present, the hygienic article of commercial type, Water-absorption core body such as sanitary towel or diaper is usually made up of Time of Fluff Slurry or non-woven fabrics, in order to improve the absorbent properties of Water-absorption core body, people have developed and add macromolecule water uptake layer in Water-absorption core body, but such sanitary towel or diaper are in use, and Water-absorption core body is susceptible to the situations such as conglomeration, fracture or clot.Sanitary towel or diaper can be applied a distortion action when this is primarily due to resource-user cost method, and Water-absorption core body can expand after absorbing a certain amount of liquid, therefore Water-absorption core body various piece is born extruding or power of pullling can be different, thus easily producing the situations such as Water-absorption core body conglomeration, fracture or clot, bring sense of discomfort to user；Additionally; owing to this Water-absorption core body is very closely knit, the absorption of liquid and the diffusion of liquid slowly, if liquid can not be absorbed in the short time; discomfort and trouble can be brought, it is impossible to it can absorb the requirement of big quantity of fluid at short notice to meet user needs to user.
Chinese patent CN101797201 discloses a kind of polymer compound core body and preparation method thereof, relates to a kind of polymer compound core body.There is provided one to be mainly used in the paper napkin and diaper, it may be achieved do not rise stick together, do not rupture, the polymer compound core body of not delamination and preparation method thereof.Polymer compound core body is provided with dust-free paper top layer, dust-free paper bottom and bulky nonwoven layer of cloth, bulky nonwoven layer of cloth is located between dust-free paper top layer and dust-free paper bottom and glueds joint with dust-free paper top layer and dust-free paper bottom adhesive, is uniformly impregnated with water-absorbing resin in bulky nonwoven layer of cloth.Urine can infiltrate in polymer compound core body quick and completely, the dust-free paper top layer of compound core body can effectively suck urine, the hydroscopic high-molecular resin layer of polymer compound core body can effectively absorb storage urine, bulky nonwoven layer of cloth can make urine quickly permeate toward bottom direction, therefore water absorption is big, and surface layer can be made to keep relatively drying regime, make human body comfortable.But, the compound core body of said structure, its bonding plane inevitably exists the glue parcel to hydroscopic high-molecular resin, thus causing the waste of hydroscopic high-molecular resin；Further, since its planar structure, more with skin contact, there is certain potential safety hazard.
