Description
Technical Field
The utility model relates to a disposable hygienic articles field especially relates to a compound core of improved generation.
Background
The most important thing is to absorb the core in disposable nursing materials such as panty-shape diapers, pull-ups, the core structure is not good, the product of making appears sticking together easily in the use, the cracked condition, perhaps absorb not well, most absorb core or absorbed layer are the absorption core of compriseing non-woven fabrics and wood pulp or fluff pulp, the absorbent properties of core has increased the polymer water-absorbent resin SAP granule in order to further increase, but the product absorbent structure who makes with such core is often very thick, can bring certain inconvenience and uncomfortable sense for the user.
Current patent No. 201620020028.6 discloses a novel absorption core, including top layer and intermediate level, the absorption core form by top layer parcel intermediate level, the top layer is hydrophilic non-woven fabrics, the intermediate level is main absorber, main absorber include fluffy absorber again and absorb cotton core, fluffy absorber comprises fluffy layer polymer of one deck and the fluffy layer material of one deck, the cotton core of absorption be the mixture of wood pulp and SAP, fluffy absorber is located the cotton core top of absorption. The fluffy layer material made of the ES fiber non-woven fabric increases the strength of the core layer, so that the core layer is not easy to layer and break, the absorption speed of the fluffy layer material is high due to the fluffy layer high molecules on the surface, the efficiency is high, the economy is realized, meanwhile, the thickness of the superposed layers of the fluffy layer high molecules and the fluffy layer material can be adjusted according to the requirement, the water absorption capacity is large due to the multi-layer absorption formed by the structure, the urine can be effectively and rapidly absorbed and stored, the use is dry and comfortable, but the whole shape of the absorption core body is improved, the common shapes of the existing absorption core body are generally straight bars, dumbbell shapes or hourglass shapes, the straight bar core body has large absorption capacity, but the high polymer absorption resin can expand for multiple times after absorbing body fluid, the front width and the rear width are consistent with the width of the crotch, and a user can feel that a. The dumbbell shape and the hourglass shape conform to the physiological characteristics of a human body, but the absorption capacity of the crotch is reduced, so that the left side and the right side of the baby have side leakage risks, and the potential harm of splayed legs of the baby is also caused.
SUMMERY OF THE UTILITY MODEL
Therefore, to foretell problem, the utility model provides a be applied to in the absorptive articles for use make the absorption core more fit and can prevent the compound core of improved generation of left and right sides edge leakage.
In order to achieve the above purpose, the utility model adopts the following technical scheme: an improved composite core body comprises an absorption core body, wherein the width of the absorption core body is defined to extend to a transverse direction, the length of the absorption core body extends to a longitudinal direction, the absorption core body comprises an upper non-woven fabric, an upper absorption layer, a middle non-woven fabric, a lower absorption layer and a bottom non-woven fabric which are arranged from top to bottom in a laminated mode, the upper absorption layer is made of a first fluffy non-woven fabric, SAP particles are uniformly distributed on the first fluffy non-woven fabric, the lower absorption layer comprises a first absorption layer, a second absorption layer and a third absorption layer which are arranged in parallel at intervals and in parallel at intervals along the transverse direction, the first absorption layer, the second absorption layer and the third absorption layer are all made of a second fluffy non-woven fabric, the SAP particles are uniformly distributed on the second fluffy non-woven fabric, two end portions of the bottom non-woven fabric in the transverse direction are folded upwards and are bonded with the upper surfaces of two sides, the absorption core body is provided with elastic strips which are longitudinally distributed at the bonding part between the bottom layer non-woven fabric and the upper layer non-woven fabric.
In a further refinement, the density of SAP particles in the second absorbent layer is greater than the density of SAP particles in the upper absorbent layer.
In a further refinement, the density of SAP particles in the second absorbent layer is greater than the density of SAP particles in the first and third absorbent layers.
In a further improvement, the elastic strip is natural rubber or an artificial elastic thread, an elastic rubber strip or an elastic film.
The further improvement is that the thickness of the first fluffy non-woven fabric is 1-3mm, and the thickness of the second fluffy non-woven fabric is 3-6 mm.
The further improvement is that the first fluffy non-woven fabric and the second fluffy non-woven fabric both adopt the gram weight of 38-45g/m2The bulky nonwoven fabric of (1).
By adopting the technical scheme, the beneficial effects of the utility model are that: the utility model has the advantages that the upper and lower absorbing layers are arranged, and the lower absorbing layer is composed of the first absorbing layer, the second absorbing layer and the third absorbing layer which are arranged side by side at intervals, so that the absorbing core body can be automatically and inwards bent under the action of the leg clamping force when the utility model is worn, the absorbing core body is prevented from gathering and accumulating at the legs, and the wearing comfort level is improved; because the elastic strip is arranged on the absorption core body, the first absorption layer and the third absorption layer can be in a natural standing state by utilizing the elastic action of the elastic strip, when the absorption core body absorbs liquid, two sides of the absorption core body are tightly attached to the skin of a human body to form a certain leakage-proof height, so that the side leakage is effectively avoided, and meanwhile, the absorption core body can be effectively prevented from being broken by arranging the upper absorption layer; furthermore, the density of the SAP particles in the second absorption layer is greater than that of the SAP particles in the upper absorption layer, and the pores of the first fluffy non-woven fabric are equivalent to the flow guide channels, so that liquid can well permeate from the channels, and even if the density of the SAP particles reduces the liquid absorption speed and capacity due to liquid absorption expansion gel, the liquid can enter the lower absorption layer from the first fluffy non-woven fabric and be absorbed by the SAP particles in the lower absorption layer during secondary absorption; furthermore, the density of the SAP particles in the second absorption layer is greater than that of the SAP particles in the first absorption layer and the third absorption layer, so that the higher absorptivity of the second absorption layer can be realized, the lower absorptivity of the first absorption layer and the third absorption layer can be realized, and the side leakage prevention effect can be further improved.
