Description
Technical field
This utility model relates to a kind of absorbent device, can prevent the double protection sanitary towel that leak side leakage and back when relating in particular to a kind of the use.
Background technology
At present, the sanitary towel of various sizes and shape is widely used in by the women and absorbs menstruation or other kenosis.Along with development of times, people, use the basic demand comfortable, that absorbability is good except requiring sanitary towel to satisfy also in continuous variation the use idea of sanitary towel, and are also more and more higher to the requirement of the leakproof of sanitary towel, permeability.But leak anti-side leakage, back is the difficult problem that sanitary napkin manufacture manufacturer needs to be resolved hurrily always.The main cause that side leakage, back leakage appear in sanitary towel has: one, when blood volume is big, skew has appearred because of the problem of sanitary towel's absorbent properties or when using sanitary towel, make absorber not have alignment liquid to discharge the position, thereby cause menses to fail in effective time, all to be absorbed, thereby residual menses or other liquid laterally or vertically flow on towel body surface, cause side leakage, back to leak; Two, after menses or other liquid are absorbed fully, in absorber, still be in liquid condition, because the variation of human body attitude, especially human body be in seat, during the posture that crouches, compressing because of the human body body weight, make to absorb that intravital menses or other liquid are squeezed and laterally, vertically flow, ooze out and form side leakage, back leakage from the joint of absorber and towel body end envelope.
In order to overcome the problem of above-mentioned side leakage, but occurred being overlapped on behind a kind of both sides flanging that adopts non-woven fabrics leakproof counterdie outer surface and respectively erected the sanitary towel that a fiber edge sealing prevents side leakage with the sanltary towel that prevents side leakage and a kind of top layer both sides at transflective liquid.But above scheme all is to fail to be absorbed body at menses in time to absorb, and produce horizontal mobility on towel body surface and form side leakage and the rhymed formula measure of separating taked, but the back leakage problem that can not prevent menses from vertically flowing and produce, after simultaneously also can't solving menses and being absorbed, be subjected to human body body weight extruding back again and the side that produces is revealed problem.
In order to solve the side leakage problem, also have a kind of absorbent commodity, it is provided with water repellent region by the vertical both sides on the liquid permeability top layer of absorbent commodity, and forms the horizontal side leakage that continuous or discrete leakproof groove prevents liquid in water repellent region.But there is following defective in this absorbent commodity: 1. the leakproof sheet material of above-mentioned absorbent commodity all coats the one side of absorber towards non-permeable bottom, certainly will hinder the permeability of this absorbent commodity; 2. the leakproof groove of above-mentioned absorbent commodity is compressed in the water repellent region, when liquid on the liquid permeability top layer horizontal mobility to the leakproof groove after, because of having blocked liquid, the leakproof sheet material in absorber, permeates, and produce laterally on the liquid permeability top layer, vertically flow and cause side leakage, back to be leaked, therefore above-mentioned absorbent commodity still is not enough to solve the horizontal side leakage problem of liquid.
Also has a kind of sanltary towel that prevents side leakage, be to have increased one deck U type leakproof PE film in liquid-tight outer inboard, though this U type leakproof PE film has solved menses be absorbed after, be subjected to human body body weight extruding back again and the horizontal leakage problem that produces, fail to prevent to leak thereafter problem.Because described U type leakproof PE film is to close shape with three side sealing absorber is wrapped up, therefore be unfavorable for the volatilization (especially in the winter time) of menses steam in the absorber simultaneously, can bring moist uncomfortable sensation to user.
