Description

Ultrathin absorption core made of bacteriostatic water-absorbing material

Technical Field

The utility model belongs to the technical field of sanitary towel, concretely relates to ultra-thin absorption core that antibacterial water absorbing material made.

Background

The main material of the sanitary towel is high molecular polymer and high molecular polymer composite paper formed by cotton, non-woven fabric, paper pulp or a composite of the above materials. The sanitary napkin is an absorbent material, and aims to solve the problems of absorption of menstrual blood and prevention of leakage during the menstrual period of women. However, women are most vulnerable to damage in sensitive areas during the menstrual period. Investigation has shown that 73% of women feel local skin itch and burning pain during menstruation, and the pruritus vulvae caused during menstruation is very painful, which cannot be solved by the traditional sanitary towel at present.

During menstruation, the pudendum is in contact with the flowing menstrual blood for a long time, so that the pudendum is easy to feel uncomfortable, the menstrual blood contains rich nutrient substances, the bacteria are fast to propagate, the pudendum is easy to infect, and genital diseases occur in severe cases; therefore, it is desirable to provide a sanitary napkin core with bacteriostatic function.

SUMMERY OF THE UTILITY MODEL

The utility model provides an ultra-thin absorption core that antibacterial absorbent material made to solve the poor technical problem of sanitary towel antibacterial among the prior art.

In order to achieve the above object, the technical solution of the present invention is:

an ultrathin absorption core body made of bacteriostatic water-absorbing materials is characterized in that the core body sequentially comprises a chitosan layer, a first adhesive layer, a base layer, a second adhesive layer and a high water-absorbing resin layer from top to bottom; the two side edges of the core body are folded downwards and are folded.

Preferably, the base layer is made by cross-lapping fluff pulp and bamboo fibers.

Preferably, the first adhesive layer and the second adhesive layer are respectively coated on the upper surface and the lower surface of the base layer.

Preferably, the surface of the core body is provided with a plurality of pressing grooves.

Preferably, the distance between the pressure groove and the side edge of the core body is 10-20mm.

Preferably, the width of the core is 50-80mm.

The utility model has the advantages that:

the base layer in the sanitary napkin core body is made of fluff pulp and bamboo fiber through cross lapping, and the bamboo fiber is a fiber with an antibacterial function and can improve the antibacterial activity of the sanitary napkin core body; meanwhile, the chitosan above the base layer also has antibacterial activity, so that the antibacterial function can be further improved.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

It should be noted that all the directional indicators (such as up, down, left, right, front, back, 8230; \8230;) in the embodiments of the present invention are only used to explain the relative position relationship between the components, the motion situation, etc. in a specific posture (as shown in the attached drawings), and if the specific posture is changed, the directional indicator is changed accordingly.

Furthermore, descriptions in the present application as to "first," "second," etc. are for descriptive purposes only and are not to be construed as indicating or implying relative importance or to implicitly indicate the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one such feature. In the description of the present invention, "a plurality" means at least two, e.g., two, three, etc., unless specifically limited otherwise.

In the present application, unless expressly stated or limited otherwise, the terms "connected" and "secured" are to be construed broadly, and thus, for example, "secured" may be a fixed connection, a removable connection, or an integral part; they may be directly connected or indirectly connected through intervening media, or they may be interconnected within two elements or in a relationship where two elements interact with each other unless otherwise specifically limited. The specific meaning of the above terms in the present invention can be understood according to specific situations by those skilled in the art.

In addition, the technical solutions between the embodiments of the present invention can be combined with each other, but it is necessary to be able to be realized by a person having ordinary skill in the art as a basis, and when the technical solutions are contradictory or cannot be realized, the combination of such technical solutions should be considered to be absent, and is not within the protection scope of the present invention.

Referring to fig. 1 to 2, an ultrathin absorption core made of bacteriostatic water-absorbing material is sequentially composed of a chitosan layer 1, a first adhesive layer, a base layer 2, a second adhesive layer and a super absorbent resin layer 3 from top to bottom; the first adhesive layer and the second adhesive layer are respectively coated on the upper surface and the lower surface of the base layer 2. The two side edges of the core body are folded downwards and are folded. In the application, chitosan powder is adopted in the chitosan layer 1, and the chitosan has better antibacterial activity and hygroscopicity and is very suitable for being used in an absorption core body of a sanitary towel. The chitosan layer is pasted in the base layer through the first adhesive layer, and the super absorbent resin layer is pasted in the base layer through the second adhesive layer. And two sides of the core body are folded towards the direction of the high polymer water-absorbent resin layer, so that the high polymer water-absorbent resin is positioned in the center of the core body, and the water-absorbing and water-retaining effects are improved.

Further, the base layer 2 is made by cross-lapping fluff pulp and bamboo fibers. Bamboo fibre has better antibacterial activity, and this application improves the antibacterial activity of core through bamboo fibre and chitosan. In addition, the fluff pulp has better water absorption, thereby improving the moisture absorption of the core.

Further, a plurality of pressing grooves 4 are formed in the surface of the core body. The design of indent 4 can play the effect of water conservancy diversion and prevent the edge leakage, indent 4 is rectangle strip or other shapes. Preferably, the distance between the indent 4 and the side edge of the core body is 10-20mm, so as to prevent the side leakage of menstrual blood.

Further, the width of the core body is 50-80mm.

The core body prepared by the utility model not only contains bamboo fiber, but also contains chitosan powder, has natural antibacterial effect, and can effectively inhibit bacteria breeding; the super absorbent resin and the chitosan powder are adhered on the base layer made of the fluff pulp and the bamboo fiber through hot melt adhesive to form a whole, so that the problem of absorption channel blockage caused by absorption and expansion of the super absorbent resin is solved, and the air permeability is greatly improved; in addition, the core of this application is thin, uses to feel more noninductive next to the shin, and the grooving that has on the core has the water conservancy diversion effect, prevents the edge leakage, improves imbibition speed.
