Abstract

The utility model discloses an absorb core relates to and absorbs core technical field. The absorbing core body comprises an upper layer, a middle layer and a lower layer, wherein the middle layer is positioned between the upper layer and the lower layer, the upper layer and the lower layer are vegetable sponge or materials added with vegetable sponge fibers, and the middle layer is vegetable sponge. The middle level is formed through chemical process by the vegetable sponge, makes to have the hole of certain size and quantity in the material to make have sufficient space to expand after the super absorbent resin imbibition, the hydrophilicity and the compliance of material can be controlled again, guarantee that the material has certain intensity, the condition that sticks together, fault can not appear in the core yet.

Description

Absorption core body

Technical Field

The utility model relates to an absorb core technical field, specifically be an absorb core.

Background

The structures of disposable sanitary products such as paper diapers and sanitary napkins are well known, and the disposable sanitary products generally comprise a liquid-permeable surface layer, a liquid-impermeable bottom layer and an absorption core arranged between the liquid-permeable surface layer and the liquid-impermeable bottom layer, the existing absorption core generally comprises wood pulp and high-molecular water-absorbent resin wrapped by non-woven fabrics or toilet paper, after water absorption, the flow guide effect in the core body is weakened due to the fact that the high-molecular water-absorbent resin expands the wood pulp and is dispersed, the absorption effect is weakened, particularly after multiple times of absorption, the effect is obviously weakened, and reverse osmosis is easy to occur.

In the common absorption core body in the market, the uppermost layer and the lowermost layer are generally dust-free paper, non-woven fabric or spunlace fabric, the middle layer is non-woven fabric, and two layers of super absorbent resin are sandwiched between the uppermost layer, the lowermost layer and the middle layer. This type of core intermediate level generally is fluffy non-woven fabrics, and super absorbent resin directly broadcasts the distribution in the both sides of fluffy non-woven fabrics and in the middle of the fluffy non-woven fabrics of part embedding, and this type of structural upper water absorbent resin easily takes place the viscose reaction and blocks up for the liquid permeability of product is not good, and it is slow to absorb liquid infiltration speed many times, and diffusion length is short, and core overall utilization is relatively poor, easily takes place the urine leakage condition when leading to imbibition many times.

In addition, the synthesis of the three materials of the dust-free paper, the non-woven fabric or the spunlace fabric contains a certain proportion of synthetic fibers, and the synthetic fibers have high cost, cannot be degraded and are easy to cause pollution.

SUMMERY OF THE UTILITY MODEL

The utility model provides an absorb core has solved in prior art, and it is not good to absorb core or cotton core liquidity, and it is slow to absorb liquid infiltration speed many times, and diffusion length is short, and the core overall utilization is relatively poor to and inhale liquid back core position and play easily sticking together, influence the baby and dress the travelling comfort, cause the core fault to shift after using easily, thereby lead to not having the absorbent and leak urine and the whole problem that produces the hard piece on the side of thick easily of core.

In order to achieve the above object, the present invention provides the following technical solutions:

an absorbing core body comprises an upper layer 1, a middle layer 5 and a lower layer 4, wherein the middle layer 5 is positioned between the upper layer 1 and the lower layer 4, the upper layer 1 and the lower layer 4 are vegetable sponge or materials added with vegetable sponge fibers 51, and the middle layer 5 is vegetable sponge.

Preferably, one or more layers of super absorbent resin 2 or a mixture of super absorbent resin 2 and loofah sponge are arranged above and below the middle layer 5.

Preferably, the middle layer 5 can be one or more layers, and when the middle layer 5 is a plurality of layers, the super absorbent resin 2 is arranged between adjacent layers at intervals.

Through implementing above technical scheme, have following technological effect: the utility model provides an absorb core, through medial improvement, the middle level comprises the vegetable sponge fiber material who has handled through chemical process, can adjust little wonderful space size and quantity, thereby make have sufficient space to expand behind the super absorbent resin imbibition, consequently can not take place the condition that the viscose blockked up and influence imbibition many times, the hydrophilicity and the compliance of control material, guarantee that the material has certain intensity, the core also can not appear sticking together, the condition of fault, the multilayer design, be favorable to the core to absorb many times, and the vegetable sponge material is with low costs, and is degradable, can not cause environmental pollution.

Detailed Description

For better understanding of the technical solutions of the present invention, the following detailed description of the embodiments provided in the present invention is provided with reference to the accompanying drawings.

The embodiment of the utility model provides a technical scheme: as shown in fig. 1-3, an absorbent core comprises an upper layer 1, a middle layer 5 and a lower layer 4, wherein one or more layers of super absorbent resin 2 are disposed above and below the middle layer 5, the middle layer 5 can be one or more layers, such as 3 layers and 4 layers, the middle layer 5 is disposed between the upper layer 1 and the lower layer 4, the upper layer 1 and the lower layer 4 are made of loofah pulp or materials added with loofah pulp fibers 51, the loofah pulp of the middle layer 5 needs to be treated by a chemical method, and different chemical treatment methods are adopted to obtain loofah pulp fibers with different pore sizes and numbers, so that the super absorbent resin 2 has enough space to expand after imbibing, and cannot cause viscose blockage to affect multiple imbibitions, and meanwhile, the chemical treatment can control the hydrophilicity and softness of the materials, and guarantee certain strength of the modified materials, and can guarantee soft, soft and good absorbency, Good hydrophilic effect, and can ensure that the core body does not stick together and is not broken

On the basis of the above embodiment, in other embodiments, more specifically, one or more layers of super absorbent resin 2 or a mixture of super absorbent resin 2 and loofah sponge are disposed above and below the middle layer 5. In this embodiment, the speed of absorbing liquid by the absorbent core can be controlled by arranging different layers of the super absorbent resin 2, and the super absorbent resin 2 can be mixed with the loofah.

In addition to the above embodiments, in other embodiments, more specifically, the middle layer 5 is one or more layers, and when the middle layer 5 is a plurality of layers, the super absorbent resin 2 is disposed at intervals between adjacent layers. In this embodiment, by setting different numbers of the middle layers 5, the conductivity inside the absorbent core can be controlled, and the infiltration speed can be increased.

In conclusion, the absorbent core body is improved by the middle layer 5, the middle layer 5 is formed by processing the loofah sponge through a chemical method, and pores with certain size and quantity exist in the material, so that the super absorbent resin 2 has enough space for expansion after imbibing liquid, the hydrophilicity and the softness of the material can be controlled, the material is ensured to have certain strength, and the core body does not have the situation of lump and fault.

The above is to the detailed introduction of the absorption core provided by the embodiment of the present invention, to the general technical personnel in this field, according to the embodiment of the present invention, there is a change part on the concrete implementation and the application range, to sum up, the content of this specification should not be understood as the limitation of the present invention.
