Description

A double-core sanitary napkin and sanitary product

technical field

The utility model relates to a sanitary article, in particular to a double-core sanitary napkin and the sanitary article.

Background technique

With the development of the economy and the improvement of living standards, people have more and more consumer demand for disposable sanitary products. At the same time, as consumption concepts become more mature and open, consumers hope to use more comfortable and safe products. As a close-fitting disposable sanitary product, sanitary napkins are particularly important in terms of comfort and water absorption.

Existing ultra-thin sanitary napkins use polymer composite paper or dust-free paper as the absorbent core. The advantage is that the thickness is very thin, generally 1-2mm, and the water absorption performance is superior, and the absorption multiple is more than 20 times. The disadvantage is that the absorption speed is relatively slow. Slow, the core body is relatively hard, the touch feeling is poor, and the consumer experience is not good, while the cotton core slim core body sanitary napkin with the advantage of softness and fit can effectively improve the comfort, improve the consumer experience, and the absorption speed is also faster. It is relatively fast, but the absorption capacity is average, the absorption ratio is within 20 times, and the thickness is relatively large, which is prone to stuffiness, odor, and bacteria breeding, which is not conducive to the health of consumers, and the cotton core is relatively easy to break and deform as the absorbent layer , side leakage occurs.

Contents of the invention

In order to overcome the deficiencies of the prior art, the utility model provides a double-core sanitary napkin and a hygienic article which are soft, comfortable and excellent in water absorption.

The technical scheme that the utility model solves its technical problem adopts is:

A double-core sanitary napkin, comprising a sanitary napkin main body, the sanitary napkin main body consists of a fabric layer, a flow guide layer, an absorption layer, a protective bottom film, a backing release paper and a coating from top to bottom, and is characterized in that The upper side of the absorption layer is a slim diffusion core, and the lower side is an ultra-thin liquid storage core.

The outer surface of the absorbing layer is provided with a wrapping layer.

An adhesive layer is arranged between the slim diffusion core and the ultra-thin liquid storage core.

The thickness of the slim diffusion core is 2-4 mm, and the weight per square meter is 100-180 grams.

The thickness of the ultra-thin liquid storage core is 0.6-2 mm, and the weight per square meter is 80-150 grams.

Both sides of the fabric layer are provided with guards.

Between the protective cover and the fabric layer, between the fabric layer and the diversion layer, between the diversion layer and the absorption layer, between the absorption layer and the protective back film, between the protective back film and the adhesive release paper With structural glue.

A hygienic product, comprising the double-core sanitary napkin.

The beneficial effects of the utility model are: the innovative use of the structure of the double-layer core body, that is, the upper side of the absorption layer is a soft and slim diffusion core body, and the lower side is an ultra-thin liquid storage core body with excellent water absorption performance. The design of the core makes the utility model not only have a good fit and touch feeling, but also can quickly absorb and diffuse menstrual blood. SPA can effectively prevent menstrual blood from seeping back, keep the surface of the sanitary napkin dry, prevent stuffy feeling, and better meet the needs of menstrual blood. The physical and mental health needs of consumers.

The sanitary products including the above-mentioned double-core sanitary napkin have the advantages of large absorption capacity, fast absorption speed, ability to keep the surface dry and comfortable for users.

Description of drawings

Below in conjunction with accompanying drawing and embodiment the utility model is further described.

Fig. 1 is the structural representation of the utility model.

Detailed ways

A double-core sanitary napkin, comprising a main body of the sanitary napkin, the main body of the sanitary napkin is a fabric layer 1, a flow guide layer 2, an absorption layer, a protective bottom film 3, an adhesive release paper 4 and an envelope from top to bottom 5. Both sides of the fabric layer are provided with guards 10 to prevent side leakage of menstrual blood. The upper side of the absorption layer is a slim diffusion core 6, and the lower side is an ultra-thin liquid storage core 7, and an adhesive layer 9 is arranged between the slim diffusion core 6 and the ultra-thin liquid storage core 7, so that The outer surface of the absorbent layer is provided with a wrapping layer 8 .

The slim diffusion core 6 is formed by mixing and pressing wood pulp and polymer absorbent resin. SuperAbsorbent Polymer (SAP) is a new type of functional polymer material containing hydrophilic groups and macromolecules with cross-linked structures. , has excellent water absorption performance, can absorb water hundreds to thousands of times heavier than itself, and has excellent water retention performance. Once it absorbs water and swells into a hydrogel, it is difficult to separate the water even if it is pressurized. The utility model adopts the slender diffusion core 6 made of SPA and wood pulp, which makes the touch feeling of the utility model soft and comfortable, and absorbs and diffuses menstrual blood at a very fast speed. SPA can effectively prevent menstrual blood from seeping back and keep the surface of the sanitary napkin dry. Prevent stuffiness. The slim diffuser core 6 was purchased from Shanghai Kaichang International Trade Co., Ltd., model number 120.

The slim diffusion core 6 has a thickness of 2-4 mm and a weight of 100-180 grams per square meter. After testing, if the thickness of the slim diffusion core and the weight per square meter are greater than this specified range, this embodiment will be too thick and heavy, which will affect the light and breathable effect of this embodiment; the thickness of the slim diffusion core and the weight per square meter If the weight is less than this specified range, it will affect the water absorption performance of this embodiment and the speed of spreading menstrual blood, and it will easily form wrinkles, causing side leakage.

The ultra-thin liquid storage core body 7 is any one of the compacted bodies made of polymer composite paper, dust-free paper or wood pulp SPA composite paper, which increases the absorption capacity of the utility model and is arranged in the The lower part of the above-mentioned slim diffusion core 6 will not affect the comfort of the utility model.

The thickness of the ultra-thin liquid storage core 7 is 0.6-2 mm, and the weight per square meter is 80-150 grams. The absorption multiple of the ultra-thin liquid storage core 7 is more than 20 times, and there is no need to design it too thick, which will affect the light, thin and breathable effect of this embodiment.

Between the protective enclosure 10 and the fabric layer 1, between the fabric layer 1 and the flow-guiding layer 2, between the flow-guiding layer 2 and the absorbing layer, between the absorbing layer and the protective bottom film 3, between the protective bottom film 3 and the adhesive Structural glue is arranged between the release paper 4 .

Another embodiment of the utility model is a sanitary product, which includes the double-core sanitary napkin, and the sanitary product includes but not limited to baby napkins, baby diapers, adult multifunctional nursing pads, anti-galactorrhea pads, etc. .

The above embodiments cannot limit the scope of protection of the invention of the utility model, and the equivalent modifications and changes made by those in the technical field without departing from the overall concept of the invention of the utility model still belong to the scope covered by the invention of the utility model within.
