Description

Technical Field

[0001] This utility model belongs to the field of absorbent core technology, specifically relating to a wood pulp meltblown absorbent core with added SAP. Background Technology

[0002] One of the key materials in intimate care products such as diapers, disposable diapers, nursing pads, and nursing pads is the absorbent core material located between the top layer and the bottom film, which has the functions of guiding, diffusing, and absorbing liquids. Currently, most commonly used absorbent cores are made of materials such as wood pulp meltblown paper, pulp-blended SAP, toilet paper, and non-woven fabric composite SAP. The main components of wood pulp meltblown absorbent core material are continuous polymer microfibers with a diameter of about 3 micrometers mixed with discontinuous wood pulp fibers with a diameter of 10-25 micrometers and a certain proportion of SAP, produced through processes such as ultrafine meltblowing, airflow forming, and roll pressing. The ultrafine meltblown fibers, with a diameter only 1 / 10 of other natural or synthetic fibers, give the material characteristics such as fluffy, soft, thin, fast absorption, good water retention, and good reverse seepage performance. When applied to disposable hygiene products, it has excellent properties such as fast absorption, large absorption capacity, and good reverse seepage performance, while also giving the finished product the characteristics of being thin, soft, and structurally stable without deformation.

[0003] However, when materials of different properties and materials are integrally formed using airflow, the addition of SAP during the production process, due to the influence of the process airflow from meltblowing and wood pulp dissolution, easily leads to SAP particle scattering and uneven material distribution. This not only makes processing more troublesome but also results in less than ideal performance. Utility Model Content

[0004] The purpose of this invention is to provide a wood pulp meltblown absorbent core with added SAP to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a wood pulp meltblown absorbent core with added SAP, comprising a body, wherein the body comprises layers one, two, three, four and five arranged from top to bottom, wherein layers one, three and five are all ultrafine meltblown PP polymer, and layers two and four are mixtures of wood pulp fiber and superabsorbent polymer (SAP).

[0006] Preferably, the body is in the form of a cloth.

[0007] The technical effects and advantages of this utility model are as follows: The pulp meltblown absorbent core is made by mixing wood pulp fiber and super absorbent resin SAP and adding it to two sets of ultra-fine meltblown PP with an included angle. After being formed into a web by airflow, it is rolled into a fabric with good connection effect, no obvious delamination, and is not easy to separate. It has excellent properties such as fast absorption speed, large absorption capacity and good reverse seepage. At the same time, it gives the finished product the characteristics of being light, thin and soft, and having a stable and non-deformable structure. Attached Figure Description

[0010] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0011] This utility model provides, for example Figure 1 The illustrated wood pulp meltblown absorbent core with added SAP includes a body, which comprises layers 1, 2, 3, 4, and 5 arranged from top to bottom. Layers 1, 3, and 5 are all made of ultrafine meltblown PP polymer, while layers 2 and 4 are mixtures of wood pulp fiber and superabsorbent polymer (SAP).

[0012] In some specific embodiments of this utility model, the body is in the form of a cloth.

[0013] Working principle: By adding a mixture of wood pulp fiber and superabsorbent polymer (SAP) to the upper and lower layers of ultrafine meltblown PP polymer, the problem of SAP particles scattering and uneven material distribution that easily occurs when SAP is added is solved. Then, layers 1, 2, 3, 4, and 5 are formed into a web by airflow and then rolled into a fabric to obtain the absorbent core.

[0014] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
