Detailed Description
To make the objects, technical solutions and advantages of the embodiments of the present invention clearer and more complete, the technical solutions in the embodiments of the present invention will be described below with reference to the embodiments of the present invention and the accompanying drawings, it is obvious that the described embodiments are some, but not all, embodiments of the present invention, and all other embodiments obtained by a person of ordinary skill in the art without creative efforts based on the embodiments of the present invention belong to the protection scope of the present invention.
The invention provides a sanitary absorption article in a first aspect, as shown in fig. 1 and fig. 2, the sanitary absorption article comprises a three-dimensional enclosure 1, a liquid-permeable surface layer 2, a diversion layer 3, a bacteriostatic layer 4, an absorption layer 5 and a breathable bottom layer 7 which are arranged in sequence from top to bottom; the liquid-permeable surface layer 2 is a fine denier hot air non-woven fabric; wherein the fine denier hot-air non-woven fabric has a single filament denier of 0.5 to 2.5 denier (for example, 0.5 denier, 0.8 denier, 1.0 denier, 1.5 denier, 2 denier or 2.5 denier); the antibacterial layer 4 is obtained by laminating antibacterial agents on two layers of spun-bonded spunlace non-woven fabrics, and the content of the antibacterial agent is 10-30 wt% (for example, 10 wt%, 12 wt%, 15 wt%, 18 wt%, 20 wt%, 22 wt%, 25 wt%, 28 wt% or 30 wt%) of the antibacterial layer; wherein the bacteriostatic agent comprises a bacteriostatic factor, a regulatory factor and activated carbon;
the sanitary absorption article also comprises a wrapping layer 6; wherein the absorption layer 5 is wrapped inside the wrapping layer 6.
It should be noted that the drawings of the present invention are provided for illustrative purposes only, and the scale of the components in the drawings is not necessarily consistent with the actual product.
In the present invention, the content of the bacteriostatic agent is 10 to 30% by mass of the total mass of the bacteriostatic layer.
It should be noted that, in the invention, the fine denier hot air non-woven fabric is used as the liquid permeability surface layer, firstly, the fine denier hot air non-woven fabric is fluffy and soft, has good hygroscopicity and air permeability, is in direct contact with the skin of a human body, and can bring very comfortable feeling to a user; secondly, adopt the hot-blast non-woven fabrics of fine denier of monofilament fineness for 0.5 ~ 2.5 denier for the non-woven fabrics structure is comparatively fluffy, the porosity is great, and liquid can pass the liquid permeability top layer fast, and then keeps the dry and comfortable nature on liquid permeability top layer.
Experiments prove that when the filament number of the fine denier hot air non-woven fabric used for the liquid-permeable surface layer is less than 0.5 denier, the process spinning is difficult; when the filament number of the fine denier hot air non-woven fabric is larger than 2.5 denier, the fiber is rough and is in direct contact with the skin of a user, and the use comfort level is reduced.
In fig. 1 and 2 of the present invention, the structural layers are peeled off from each other in order to clearly illustrate the positional relationship between the structural layers of the present invention, and it should be understood that the structural layers of the present invention are in close and/or partial close contact with each other.
According to some preferred embodiments, the flow guiding layer 3 is selected from at least one of a through-air nonwoven fabric and a spunbond nonwoven fabric.
In the invention, the flow guide layer is preferably a hot air non-woven fabric which has the characteristics of fluffiness, air permeability and the like, and a large number of gaps can still be reserved after the non-woven fabric is wetted or absorbs liquid, so that a large amount of liquid can be rapidly received and transmitted, and the phenomenon that the use experience of consumers is influenced by the liquid concentrated on the liquid permeable surface layer is avoided.
According to some preferred embodiments, the bacteriostatic factor is at least two selected from cyperus rotundus, honeysuckle, clove and lavender;
the regulating factor is at least one selected from radix Angelicae sinensis and herba Leonuri.
According to some preferred embodiments, the components of the bacteriostatic agent in the bacteriostatic layer 4 comprise: 15-25 wt% (for example, 15 wt%, 18 wt%, 20 wt%, 23 wt% or 25 wt%) of the bacteriostatic factor, 30-50 wt% (for example, 30 wt%, 35 wt%, 40 wt%, 45 wt% or 50 wt%) of the regulatory factor, and 25-55 wt% (for example, 25 wt%, 30 wt%, 35 wt%, 40 wt%, 45 wt%, 50 wt% or 50 wt%) of the activated carbon.
It should be noted that, in the invention, the bacteriostatic factor, the regulatory factor and the activated carbon are added in the bacteriostatic layer, the inventor finds that the bacteriostatic factors such as cyperus rotundus, honeysuckle, clove, lavender and the like have the antibacterial and anti-inflammatory effects, the angelica and the motherwort as the regulatory factors can relieve pain and regulate menstruation, the activated carbon has excellent adsorbability, the passive permeation process of liquid can be converted into the active adsorption process, the liquid can be ensured to be absorbed into the absorption layer in time, the bacteriostatic factor, the regulatory factor and the activated carbon are mutually synergistic, the liquid can be more quickly permeated into the absorption layer, and the bacteriostatic taste, the regulating factor and the activated carbon can be effectively inhibited from bacteria, and the menstruation and the pain can be relieved.
For example, when the bacteriostatic factors are cyperus rotundus and honeysuckle and the regulating factor is angelica, the bacteriostatic factor is 25 wt%, the regulating factor is 30 wt% and the active carbon is 45 wt%; when the bacteriostatic factors are clove and lavender and the regulating factor is motherwort, the bacteriostatic factor is 25 wt%, the regulating factor is 30 wt% and the active carbon is 45 wt%; wherein, the proportion of two bacteriostatic factors in the bacteriostatic factors is 1: 1; the inventor finds that if the content of the antibacterial factor is too low, the antibacterial and anti-inflammatory effects cannot be achieved; if the regulating factor is too little, regulating menstruation and relieving pain cannot be realized; if the content of the activated carbon is less, the absorption rate of the liquid is reduced, so that the content of the bacteriostatic factor in the bacteriostatic agent is 15-25 wt%, the content of the regulating factor is 30-50 wt%, and the content of the activated carbon is 25-55 wt%. When the content of each component in the bacteriostatic agent exceeds the above range, the components are difficult to be fully and uniformly mixed, and the operation difficulty in the process is increased.
According to some preferred embodiments, the absorbent layer 3 and the wrapping layer 6 are both wet-process super absorbent resin absorbent paper; wherein the gram weight of the super absorbent resin absorbent paper is 30-350 g/m2(for example, it may be 30g/m2、50g/m2、80g/m2、100g/m2、150g/m2Or 200g/m2、250g/m2、300g/m2Or 350g/m2)；
