Problems solved by technology

However, the speed of absorbing liquid is relatively slow, and since there is only a thin layer of upper absorbent layer on the polymer water-absorbent resin layer, after the polymer water-absorbent resin layer absorbs a large amount of liquid, it is easy to reverse osmosis to the upper absorbent layer. The user has a sticky and wet feeling, and the comfort of use is greatly reduced

no. 1 example

[0030] Such as figure 1 and figure 2 Shown is the first embodiment of a fast-absorbing core of the present invention. The core 1 includes a hot-air non-woven fabric layer 11, a fluff pulp layer 12, an upper absorbent layer 13, and a polymer water-absorbing resin layer arranged in sequence from top to bottom. 14. The lower absorbent layer 15, the core body 1 is also provided with a number of diversion grooves 2.

[0031] The core body 1 of the present invention has fast absorption speed, reduces reverse osmosis, can reduce liquid leakage, improves product utilization rate, and improves product softness. At the same time, it can solve the bad feel of the particles caused by the polymer water-absorbing resin material when touching the product. Specifically, the hot-air non-woven fabric layer 11 can quickly penetrate the liquid in the upper layer to the lower layer, and at the same time fix the fluff pulp layer 12 in the lower layer to prevent the fluff pulp from leaking and lu...

Embodiment 2

[0041] Such as image 3 and Figure 4 It is the second embodiment of a quick-absorbing diaper. This embodiment is a quick-absorbing diaper comprising the core of Example 1, including a main body 3, a front waist 4, a back waist 5, and a leak-proof partition 6. One end of the main body 3 is connected to the front ring waist 4, and the other end is connected to the rear ring waist 5. Leak-proof partitions 6 are arranged on both sides of the main body 3. The main body 3 includes the core body 1, the surface layer 31, the cover layer 32, The leak-proof bottom film 33, the surface layer 31, the covering layer 32, the core body 1, and the leak-proof bottom film 33 are arranged in sequence from top to bottom.

[0042] The diapers of Example 2 are lighter and thinner, and the polymer has good water-locking performance. After the product absorbs urine, it is soft and does not become lumpy. At the same time, it has the effect of large absorption capacity, fast absorption speed, and str...

Abstract

The invention relates to the technical field of absorption articles, in particular to a rapid-absorbing core and a paper diaper. The core comprises a hot air non-woven fabric layer, a fluff pulp layer, an upper absorption layer, a high-molecular water-absorbent resin layer and a lower absorption layer which are sequentially arranged from top to bottom, and the core is further provided with a plurality of diversion trenches. The invention aims at overcoming the defects that the core of an existing absorption article is low in liquid absorption speed, large in back seepage and prone to lumping,provides a rapid-absorbing core which is high in absorption speed, less in back seepage, not prone to lumping and capable of improving comfort. The invention further provides a paper diaper with the rapid-absorbing core. The paper diaper has the effects of being lighter and thinner, good in macromolecular water locking performance, soft and free of lumping after absorbing urine, large in absorption amount, high in absorption speed and high in water locking performance; and the specific diversion trench design can accelerate the absorption speed of the paper diaper, reduce reverse osmosis, reduce urine leakage and improve the product utilization rate.

Description

technical field [0001] The invention relates to the technical field of absorbent articles, and more specifically, to a fast-absorbing core and a diaper. Background technique [0002] Absorbent products are key components used in disposable hygiene products such as diapers, sanitary napkins and other items for absorbing various liquids. Among them, it is the core body of the absorbent article that plays the main role of absorption. The absorption speed of the existing absorbent articles is slow, and it is easy to lump after absorbing liquid or leakage occurs when the absorption is large. And most of the absorbent articles adopt fluffy cloth as the main absorbent layer, which causes the whole absorbent core body to be thick and bloated, which brings discomfort to the user. [0003] The reference document (the publication number is CN 209236609U) discloses a gourd-shaped diaper core body, including an upper absorbent layer, a lower absorbent layer and a polymer water-absorben...
