Description

Technical Field

[0001] The utility model relates to an absorbent core, in particular to an instant-absorbing and quick-drying absorbent core. Background Art

[0002] The absorbent core is often used in the production of diapers, and diapers are used by people who cannot defecate independently, so as to avoid excretion into the human body and cause pollution to the outside world.

[0003] Most of the products on the market are made of wood pulp core, but wood pulp core products are relatively thick, with poor air permeability and diffusion conductivity. They are prone to moisture after long-term use, causing skin rash and allergies. The strength of wood pulp is poor, and it is easy to cause the absorbent to break and clump after exercise, causing urinary incontinence. The traditional composite core has a slow absorption speed, and the absorbent resin expands after absorption to block the absorption channel, thus causing urinary incontinence.

[0004] In the past, after the absorbent core in diapers absorbed the liquid, the liquid excreted by the human body often had an odor. The liquid exuded from the human body was not only easy to pollute the outside world, but also easy to be affected by the outside world due to the odor. Utility Model Content

[0005] In view of the technical defects existing in the background technology, the utility model proposes an instant absorption and quick-drying absorbent core, which solves the above technical problems and meets the actual needs. The specific technical solution is as follows:

[0006] A quick-absorbing and quick-drying absorbent core comprises: a diffusion layer, a guide groove, a deodorizing layer, a liquid guiding layer and an absorption layer, wherein the diffusion layer is provided with two layers, and the guide groove, the deodorizing layer, the liquid guiding layer and the absorption layer are stacked in sequence between the two diffusion layers; one side of one of the two diffusion layers is in close contact with the external body, and the other side of the diffusion layer is adjacent to the surface of the deodorizing layer below, a plurality of guide grooves are provided, the openings of the guide grooves are treated toward the lower surface of the diffusion layer, and a plurality of guide grooves are respectively provided outside the deodorizing layer.

[0007] The two diffusion layers are respectively facing inwards of each other, and one of the two diffusion layers is connected to the deodorizing layer, and the other diffusion layer is connected to the absorbing layer; the two diffusion layers and the connected deodorizing layer and the absorbing layer are connected via the arranged liquid guiding layer; the other diffusion layer is opposite to the diffusion layer which is in close contact with the human body outside, and is adjacent to the outside.

[0008] A plurality of the guide grooves are evenly arranged on the surface of the deodorizing layer, and the openings of the guide grooves face the lower surface of one of the two diffusion layers; a cotton layer is arranged in the grooves of the guide grooves and between the adjacent diffusion layers; the other side of the guide grooves is bonded and fixed to one side of the liquid conducting layer; the deodorizing layer provided with the guide grooves is made of water-absorbing resin.

[0009] The liquid-conducting layer is formed by placing ES fiber pads on polypropylene non-woven fabrics and combining them through a spunlace process.

[0010] The absorption layer is composed of filament fibers and a water-absorbing resin layer.

[0011] The beneficial effects of the utility model are:

[0012] The deodorizing layer of the utility model adopts a plurality of guide grooves to allow the introduced liquid to be quickly conducted and also to guide and diffuse. The liquid introduced into the plurality of guide grooves passes through the diffusion layer above, which is in close contact with the human body outside. The liquid discharged by the human body passes through the diffusion layer until it reaches the plurality of guide grooves. After the deodorizing layer with the guide grooves absorbs the liquid, it deodorizes the smell of the liquid. After the guide grooves absorb the liquid, the deodorizing layer in an overflowing state flows the introduced liquid downward, and is led out to the absorption layer below through the liquid guide layer, and the absorption layer stores the liquid.

[0013] Among them, the arrangement of a plurality of guide grooves can reduce and avoid excessive contact of the deodorizing layer with the human body, thereby causing insufficient air permeability. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] Figure 2 The present invention is a schematic diagram of the distribution structure of the guide grooves of an instant-absorbing and quick-drying absorbent core. DETAILED DESCRIPTION

[0016] The implementation methods of the present invention are described below in conjunction with the accompanying drawings and relevant embodiments. The implementation methods of the present invention are not limited to the following embodiments, and the present invention involves relevant necessary components in this technical field, which should be regarded as common knowledge in this technical field and can be known and mastered by technical personnel in this technical field.

[0017] like Figure 1 and Figure 2As shown, an instant absorption and quick-drying absorption core comprises: a diffusion layer 1, a guide groove 2, a deodorizing layer 3, a liquid guiding layer 4 and an absorption layer 5, wherein the diffusion layer 1 is provided with two layers, and are respectively stacked up and down, and the guide groove 2, the deodorizing layer 3, the liquid guiding layer 4 and the absorption layer 5 are respectively stacked in sequence between the two diffusion layers 1; one side of one of the two diffusion layers 1 is in close contact with the body outside, and the other side of the diffusion layer 1 is adjacent to the surface of the deodorizing layer 3 below, and a plurality of the guide grooves 2 are opened, and the openings of the guide grooves 2 are treated toward the lower surface of the diffusion layer 1, and a plurality of the guide grooves 2 are respectively opened outside the deodorizing layer 3.

[0018] The deodorizing layer 3 of the utility model adopts a plurality of guide grooves 2 to allow the introduced liquid to be quickly conducted and also to be guided and diffused. The liquid introduced into the plurality of guide grooves 2 passes through the diffusion layer 1 above, and the diffusion layer 1 is in close contact with the human body outside. The liquid discharged by the human body passes through the diffusion layer 1 until it reaches the plurality of guide grooves 2. After the deodorizing layer 3 with the guide grooves 2 absorbs the liquid, it deodorizes the smell of the liquid. After the guide grooves 2 absorb the liquid, the deodorizing layer 3 in the overflowing state flows the introduced liquid downward, and is led out to the absorption layer 5 below through the liquid guide layer 4, and the absorption layer stores the liquid.

[0019] The arrangement of a plurality of guide grooves 2 can reduce and avoid excessive contact of the deodorizing layer 3 with the human body, thereby causing insufficient air permeability.

[0020] The two diffusion layers 1 are respectively facing inwards of each other, and one of the two diffusion layers is connected to the deodorizing layer 3, and the other diffusion layer is connected to the absorbing layer 5; the two diffusion layers 1 and the connected deodorizing layer 3 and the absorbing layer 5 are connected via the arranged liquid guiding layer 4; the other diffusion layer 1 is opposite to the diffusion layer 1 which is in close contact with the human body outside, and is adjacent to the outside world.

[0021] After adopting the above structure, it needs to be further explained that the two diffusion layers 1 are made of one or two of dust-free paper, viscose polyester spunlace cloth, spunbond cloth or hot air cloth.

[0022] A plurality of the guide grooves 2 are evenly arranged on the surface of the deodorizing layer 3, and the openings of the guide grooves 2 face the lower surface of one of the two diffusion layers 1; a cotton layer is arranged in the grooves of the guide grooves 2 and between the adjacent diffusion layers 1; the other side of the guide grooves 2 is bonded and fixed to one side of the liquid guiding layer 4; the deodorizing layer 3 provided with the plurality of the guide grooves 2 is made of water-absorbing resin.

[0023] After adopting the above structure, it needs to be further explained that the water-absorbing resin used in the deodorizing layer 3 is of model OC-PD80, which is formed into a plurality of strip-shaped grooves evenly distributed on the upper side of the liquid guide layer after passing through a polymer mold. The number of strips is 5-10, and the width of each guide groove 2 is 15mm-25mm, and the groove spacing between several guide grooves 2 is 10mm-20mm.

[0024] When the width of several guide grooves 2 is less than 15 mm, it is easy to cause the guide grooves 2 to be unable to flow into the liquid better, so that the liquid seeps out of the guide grooves 2, and at the same time, the opening of the guide grooves 2 makes the opening look like a flat surface layer; and when the width of several guide grooves 2 is greater than 25 mm, it is easy to cause an overly large groove shape, which easily creates a sense of barrier when it fits the human body.

[0025] When the gap between several guide grooves 2 is less than 10 mm, the guide grooves 2 may be too dense and difficult to achieve the diversion effect; and when the gap between several guide grooves 2 is greater than 20 mm, the surface width between the guide grooves 2 may be too large, which makes it difficult to divert the liquid into the guide grooves 2, making the setting of the guide grooves 2 meaningless.

[0026] The deodorizing layer 3 uses the OC-PD80 model, which is a super absorbent resin (SAP). The main feature of SAP resin is its strong water absorption capacity, which can absorb hundreds of times its own weight of water, and is not easy to dehydrate under pressure. This makes them perform well in applications that require efficient water absorption and water retention. After absorbing the liquid with odor, it locks the liquid to prevent it from seeping out. At the same time, after the liquid cannot seep out, it also prevents the odor from seeping out. The diffusion layer 1 of the surface layer also further prevents the odor from permeating outward.

[0027] The cotton layer is used to absorb liquid from the surface of the diffusion layer 1 and guide it to the deodorizing layer 3 , wherein the cotton layer is made of cotton with a larger mesh. This setting can provide an adsorption effect and also allow the adsorbed liquid to seep into the deodorizing layer 3 .

[0028] The liquid-conducting layer 4 is formed by placing ES fibers on a polypropylene non-woven fabric and combining them through a spunlace process.

[0029] After adopting the above structure, it needs to be further explained that the weight of the liquid-conducting layer 4 is 25-50 gsm, the ES fiber layer is the upper layer, and the polypropylene layer is the lower layer. This weight can prevent the utility model from being too heavy, thereby causing discomfort in carrying.

[0030] The liquid-conducting ES fiber layer provides absorption space for the deodorizing layer, and the polypropylene layer can further increase diffusion, thereby improving dryness after absorption and reducing the occurrence of allergies.

[0031] The ES fiber layer is made by a variety of non-woven fabric processing methods, such as hot rolling, hot air, needle punching, wet processing, etc. This fiber is a two-component skin-core structure composite fiber. The skin layer has a low melting point and good softness, while the core layer has a high melting point and high strength. After the fiber is heat-treated, part of the skin layer melts and acts as a bond, bonding the fiberized points in the layer together to form a hot air nonwoven fabric. Since ES fiber has the characteristic of low thermal shrinkage, the ES fiber layer has good dimensional stability.

[0032] In addition, the ES fiber layer has good moisture absorption, air permeability, filtration, thermal insulation and other characteristics, so it is also widely used in sanitary materials, thermal insulation filling materials, filtration materials and other fields.

[0033] The absorption layer 5 is composed of filament fibers and a water-absorbing resin layer.

[0034] After adopting the above structure, it needs to be further explained that the absorption layer 5 is composed of filament fibers and a water-absorbing resin layer. The filament fibers are evenly spread on the diffusion layer 1 below, and then the water-absorbing resin is sprayed on the filament fibers.

[0035] The filament fibers mentioned above are a mixture of one or more of viscose fiber, bamboo fiber, and lyocell fiber, and the fiber length is 54 mm.

[0036] The absorption layer 2 contains filament water-absorbing fibers, which can quickly store liquid while ensuring diffusivity.

[0037] The above is only a preferred embodiment of the present invention. It should be pointed out that ordinary technicians in this technical field can make several improvements and modifications without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
