Absorbent

Abstract

An absorbing product comprises a fluid-permeability top piece, an absorbing core body and a non-fluid-permeability bottom piece, wherein the fluid-permeability top piece, the absorbing core body and the non-fluid-permeability bottom piece are sequentially stacked from top to bottom, at least one absorbing sub-layer in the absorbing core body of the absorbing product is provided with a plurality of through holes which longitudinally penetrate through the at least one absorbing sub-layer, and in the at least one absorbing sub-layer provided with the through holes, the hole diameter of the upper end of the through holes in the absorbing sub-layer closest to the fluid-permeability top piece is smaller than the hole diameter of the lower end. Due to the fact that the through holes which longitudinally penetrate through the absorbing core body are formed in the absorbing core body, a liquid containing space is provided for viscous liquid, the contact area of the viscous liquid and the absorbing product is relatively increased, and accordingly absorption of the viscous liquid is quickened; in addition, in the at least absorbing sub-layer provided with the through holes, due to the shape that the hole diameter of the upper end of the through holes in the absorbing sub-layer closest to the fluid-permeability top piece is smaller than the hole diameter of the lower end, the reverse osmosis of the viscous liquid to the surface of the absorbing product can be reduced, and the overall comfort level of the absorbing product is improved.

Description

technical field [0001] The present invention relates to an absorbent article. Background technique [0002] Currently common absorbent products generally include: a liquid-permeable top sheet, a liquid-impermeable back sheet, and an absorbent core disposed between the top sheet and the back sheet to absorb liquid. [0003] The liquid-absorbing absorbent core in existing absorbent products is usually made of fluff pulp, which has good liquid absorption and diffusion capabilities by utilizing the capillary phenomenon of the fine capillaries between the fluff pulp of the absorbent core. In order to further improve the absorption and diffusion capacity of absorbent products, it is often improved by reducing the capillary diameter of the fluff pulp. For example, proper compaction of the absorbent core, embossing of flow channels on the absorbent body, etc. However, when the above measures have been taken, the absorption capacity of absorbent products to viscous liquids such as ...

Problems solved by technology

However, when the above measures have been taken, the absorption capacity of absorbent products to viscous liquids such as menstrual blood has also decreased. Sometimes, the viscous liquid may block the capillary, causing the absorbent product to take longer to absorb the viscous liquid, and the compaction of the absorbent core will also cause the overall stiffness of the absorbent product, affecting the comfort of the product

[0004] In the prior art, for the above-mentioned problems, through-holes are usually provided in absorbent products to quickly absorb liquid or viscous liquids, but in fact, when viscous liquids and the like accumulate in the through-holes, due to the slow flow of viscous liquids And it is easy to block the capillary, causing the absorption capacity of the absorbent core to decrease. The liquid or viscous liquid that is not absorbed in time will be squeezed into the absorbent product during the user's exercise, so that the liquid or viscous liquid accumulated in the through hole Easy to bleed back to the surface of absorbent products in large quantities, causing discomfort to users
