Description
Technical field
The invention belongs to hygienic article technical field, concretely relate to a kind of composite water absorbing core body and preparation method thereof.
Background technology
Water-absorption core body is to manufacture one of main materials of hygienic article such as sanitary towel, diaper, diaper, protective pad.At present, the sanitary towel of commercial type or the Water-absorption core body of diaper or absorbed layer are made up of Time of Fluff Slurry or non-woven fabrics, in order to improve the absorbent properties of Water-absorption core body or absorbed layer, people add macromolecule water uptake layer in Water-absorption core body, but such sanitary towel or diaper are in use, Water-absorption core body or absorbed layer are susceptible to the situation of conglomeration, fracture or clot.Can to one distortion action of applying of sanitary towel or diaper when this is mainly due to resource-user cost method, and Water-absorption core body can expand after absorbing substantial amounts of liquid, therefore Water-absorption core body various piece is born extruding or power of pullling can be different, thus easily producing the situation of Water-absorption core body conglomeration, fracture or clot, bring sense of discomfort to the user of sanitary towel or diaper；Additionally, due to this Water-absorption core body very closely knit; the absorption of liquid is with the diffusion of liquid slowly; this is for requiring at short notice to absorb the sanitary towel of big quantity of fluid or diaper is a great problem; if being easy for causing fluid seepage because can not be absorbed by liquid in the short time, make troubles to user.
Chinese patent CN2225487 discloses a kind of high molecular water absorption composite paper, and paper using or fabric make surface layer and bottom, and one layer of middle folder adds or be not added with the water-absorbing resin layer of the wood fiber, closes by glue laminated and there is adhesive layer.It is disadvantageous in that: surface layer, bottom, sandwich layer fiber species single, all adopt the single wood fiber, thus pull resistance be poor；And the existence of glue-line can be substantially reduced water absorption and the fiber bulkiness of paper.
Chinese patent CN101797201A discloses one and is 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.It is disadvantageous in that: (1) dustless ply of paper aperture is bigger, hydroscopic high-molecular resin is easily run out, and makes human allergy, and the hydroscopic high-molecular resin on (2) non-woven fabrics is evenly distributed in non-woven fabrics, the lock outlet capacity of hydroscopic high-molecular resin cannot be played completely, it is easy to cause waste.
Chinese patent CN103637883A discloses a kind of Water-absorption core body for hygienic article, including upper sealing coat, water accepting layer and lower sealing coat, described water accepting layer is overlapped mutually up and down by the lock water layer inhaling layer and more than a layer wink more than two-layer and forms, and the top layer of water accepting layer and bottom are and wink inhale layer；With weight, inhale in described wink layer be the wood pulp cellulose by 50～90% and 10～50% binding agent be mixed；Described lock water layer is made up of the water absorbing polymer particle accounting for water accepting layer weight 15～75%；Described upper sealing coat or lower sealing coat adopt the one in ES fibrous layer, dust-free paper or non-woven fabrics.Water absorbing polymer particle uniform spreading is sprinkled upon by this invention to be inhaled on layer in the first wink, is extremely difficult to the effect of absorption rapidly when amount of liquid is bigger, and water retention property is without ideal, it is easy to the phenomenons such as side leakage occur, brings inconvenience to user；It addition, this invention is in use, owing to the brute force of wood pulp is big not, during resource-user cost method, to one distortion action of applying of sanitary towel or diaper, the easy conglomeration of Water-absorption core body, fracture or clot, sense of discomfort can be brought to user.
