Description
Technical field
The invention belongs to hygienic article technical field, specifically relate to a kind of composite water absorbing core body and preparation method thereof.
Background technology
Water suction core body is one of main material of manufacturing by the hygienic article such as sanitary towel, diaper, diaper, protective pad.At present, the sanitary towel of selling on the market or water suction core body or the absorbed layer of diaper are to be all made up of Time of Fluff Slurry or non-woven fabrics conventionally, in order to improve the absorbent properties of water suction core body or absorbed layer, people have increased macromolecule water uptake layer in water suction core body, but such sanitary towel or diaper are in use, easily there is the situation of conglomeration, fracture or clot in water suction core body or absorbed layer.This is mainly because user can be to the distortion action that applies of sanitary towel or diaper when movable, and water suction core body can expand after absorbing a large amount of liquid, therefore the extruding that the core body various piece that absorbs water is born or the power of pullling can be different, thereby easily produce the situation of the conglomeration of water suction core body, fracture or clot, bring sense of discomfort to the user of sanitary towel or diaper; In addition due to very closely knit of this water suction core body; the absorption of liquid and the diffusion of liquid are very slow; this is a great problem for the sanitary towel or the diaper that require at short notice to absorb large quantity of fluid; if because Liquid Absorption just easily can not be caused to fluid seepage in the short time, made troubles to user.
Chinese patent CN 2225487 discloses a kind of high molecular water absorption composite paper, and paper using or fabric are made surface layer and bottom, and therebetween one deck adds or do not add the water-absorbing resin layer of the wood fiber, closes and has adhesive layer by glue laminated.Its weak point is: the fiber species of surface layer, bottom, sandwich layer is single, all adopt the single wood fiber, thereby pull resistance is poor; And the existence of glue-line can reduce water absorption and the fiber bulkiness of paper greatly.
Chinese patent CN 101797201A discloses one and has been mainly used in the paper napkin and diaper, can not realize 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 bulk nonwoven layer, bulk nonwoven layer is located between dust-free paper top layer and dust-free paper bottom and with dust-free paper top layer and dust-free paper bottom adhesive and is gluedd joint, and is evenly impregnated with water-absorbing resin in bulk nonwoven layer.Its weak point is: (1) dustless ply of paper aperture is larger, 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 that cannot bring into play hydroscopic high-molecular resin completely, easily causes waste.
Chinese patent CN103637883A discloses a kind of water suction core body for hygienic article, comprise sealing coat, water accepting layer and lower sealing coat, described water accepting layer inhales layer by two-layer above wink and lock water layer more than one deck is formed by stacking up and down mutually, and the top layer of water accepting layer and bottom are and inhale in wink layer; In weight percentage, inhale layer in described wink and be by 50～90% wood pulp cellulose and 10～50% binding agent and be mixed; Described lock water layer is made up of the water absorbing polymer particle that accounts 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.This invention is sprinkled upon water absorbing polymer particle uniform spreading to inhale layer the first wink above, is difficult to reach the effect of rapid absorption in the situation that amount of liquid is larger, and water retention property also can be desirable, and the phenomenons such as side leakage easily occur, and brings inconvenience to user; In addition, this invention in use, because the brute force of wood pulp is large not, can be to the distortion action that applies of sanitary towel or diaper when user is movable, the easy conglomeration of water suction core body, fracture or clot, bring sense of discomfort to user.
