Description

Composite absorbent core for hygiene products

technical field

The utility model relates to a sanitary product, in particular to a composite water-absorbing core body.

Background technique

Composite absorbent cores are widely used. At present, the composite absorbent cores of hygienic products on the market, such as sanitary napkins or paper diapers, are usually made of fluff pulp or non-woven fabrics. In order to improve the absorption performance of composite absorbent cores, people have developed In order to increase the polymer water-absorbing layer in the composite water-absorbing core, but during the use of such sanitary napkins or paper diapers, the composite water-absorbing core is prone to agglomeration, breakage or curling. This is mainly because the user will exert a twisting effect on the sanitary napkin or diaper when they are active, and the composite absorbent core will expand after absorbing a certain amount of liquid, so the extrusion or pulling force on each part of the composite absorbent core will increase. different, so that the composite water-absorbent core is prone to agglomeration, breakage or curling, which will bring discomfort to the user; in addition, because the composite water-absorbent core is very dense, the absorption and diffusion of liquid are very slow, if Failure to absorb liquid in a short time will bring discomfort and trouble to the user, and cannot meet the user's requirement that the liquid can absorb a large amount of liquid in a short time. the

Chinese patent CN1658810 discloses a multilayer absorbent core containing synthetic fibers to improve the liquid transfer properties of the resulting absorbent product. Synthetic fibers in the innermost and/or middle layer of the absorbent core improve inter alia the rewet properties of the absorbent article. The absorbent core can be incorporated into many absorbent articles, including diapers, feminine hygiene products, and incontinence pads.

Chinese patent CN1649554 discloses a disposable absorbent product such as sanitary napkin, panty liner, baby diaper, adult incontinence product and sweat pad. Absorbent articles located on their wearer-facing surface in areas designated for deposition of liquids have a single layer topsheet on which liquids to be absorbed during use of the article are located. The absorbent article also includes a backsheet forming the liquid barrier surface and an integral absorbent core positioned between the topsheet and the backsheet. The integral core improves the liquid handling capabilities of the absorbent article and increases the concealment effect of the article, ie the ability to hide stains due to absorbed liquid. This is especially beneficial for articles intended to absorb high color intensity such as menstrual fluid or urine of the elderly.

The existing composite water-absorbent cores for absorbing and storing liquid generally have the following disadvantages: the structure of the composite water-absorbent core is not reasonable enough, the polymer of the composite water-absorbent core is not suitable for selection (small absorption, slow absorption) and uneven distribution ( Due to the performance of the equipment); the selected middle layer is not suitable, so that the polymer cannot enter and the diffusion is slow; the surface layer is easy to delaminate, and it is easy to lump, agglomerate, and break during use, causing the liquid to absorb quickly and cause side leakage and other shortcomings.

Utility model content

In order to overcome the shortcomings of the prior art, the utility model provides a polymer water-absorbing core body with good absorption effect and large absorption capacity.

A composite water-absorbing core for sanitary products, the composite core includes a fabric flow-guiding layer, an absorbing layer and a fabric barrier layer, the absorbing layer is arranged between the fabric flow-guiding layer and the fabric barrier layer, and the absorbing layer The polymer water-absorbing resin is evenly distributed.

The utility model is provided with a fabric diversion layer, an absorption layer and a fabric barrier layer, the fabric diversion layer can effectively absorb liquid, the absorption layer can quickly penetrate the liquid to the bottom layer, and the polymer water-absorbing resin layer in the absorption layer can effectively absorb and store For liquids, the fabric barrier keeps liquids from seeping out and locks liquids inside the absorbent layer.

Preferably, the composite water-absorbent core further includes a first high-molecular water-absorbent resin layer and a second high-molecular water-absorbent resin layer, and the first high-molecular water-absorbent resin layer is located between the fabric flow-guiding layer and the bulky non-woven fabric layer , the second polymer water-absorbing resin layer is located between the bulky non-woven fabric layer and the fabric barrier layer.

Preferably, the absorbing layer is bonded to the fabric flow-guiding layer and the fabric barrier layer through an adhesive.

Preferably, the fabric flow guiding layer, the absorbing layer and the fabric barrier layer are integrated by seaming.

Preferably, the absorbent layer is made of bulky non-woven fabric. Various suitable fabrics such as non-woven fabric, dust-free paper, toilet paper, etc. can be selected for the fabric diversion layer and the fabric barrier layer.

The utility model has the advantages of simple structure, reasonable design and large absorption capacity, which can quickly and completely infiltrate liquid into the composite water-absorbing core body, keep the surface layer in a relatively dry state, and improve user comfort.
