Multilayered structure absorbing core used for nursing pad and manufacturing method thereof

Abstract

The invention provides a multilayered structure absorbing core used for a disposable absorbing product and a manufacturing method thereof. The absorbing core is formed by pressing each layer; a latticed groove is formed in the surface of the absorbing core; the groove depth of the crossed points of the latticed groove is larger than the groove depth of the non-crossed points. A new synchronous staggered layer compaction process is adopted, namely, when the absorbing core is pressed at a circular truncated cone structure in a punctiform way, the absorbing core is not completely pressed by a linear netty trapezoid compaction mechanism with the height lower than that of the circular truncated cone structure, and the absorbing core is divided into a plurality of raised small spaces; under the condition of keeping the drainage function of a flow guide layer and a liquid storage layer, the shift of a polymer absorbent material in the absorbing core is completely limited, and the intensity of a core body is increased; through adjusting the structure and the manufacturing process of the core body, the liquid absorbing amount of the improved multilayered structure absorbing core is larger, the liquid absorbing speed is rapider, and the intensity is increased.

Description

technical field [0001] The invention belongs to the field of sanitary and nursing products, and relates to an absorbent core for disposable absorbent products, especially nursing pads; in particular, it relates to a multi-layer composite liquid-absorbing structure for disposable absorbent products, especially nursing pads absorbent core. The invention also relates to a preparation method of the absorbent core, in particular to a method for preparing the absorbent core by adopting a synchronous split-layer compaction process. Background technique [0002] Existing disposable absorbent products such as nursing pads have many problems during use by consumers: [0003] For example, the polymer water-absorbing material is easily exposed on the surface of the nursing pad. In serious cases, the polymer water-absorbing material exposed on the surface of the nursing pad will rub against the user's skin and cause the user's body to be injured; [0004] For example, polymer water-abs...

AI Technical Summary

Problems solved by technology

[0005] For example, after the nursing pad absorbs liquid, a lot of liquid is not smoothly diverted in the nursing pad, resulting in low absorption speed of the absorbent core. get bedsores;

[0006] For example, the liquid absorption capacity of the nursing pad is insufficient, and the nursing pad needs to be replaced frequently during medical care and medical operations, which increases the work intensity of the nursing staff. In serious cases, frequent replacement of the nursing pad will increase the pain of the patient and increase the workload of the medical staff. Work intensity;

[0007] For example, the tensile strength of nursing pads is low, and nursing pads are often torn during medical care and medical operations. In serious cases, dirty liquids will stain bedding and may cause bacterial infections

[0008] The above situation is a phenomenon that often occurs in the medical care industry. This is because the absorbent core of the nursing pad is not perfect in terms of liquid absorption, liquid absorption speed, and use strength.

[0009] Therefore, an urgent problem to be solved in the production of nursing pads is to limit the migration of polymer water-absorbing materials in the absorbent core.

When the polymer water-absorbent material in the absorbent core of the nursing pad transfers, accumulates, and moves away from the cotton core, the nursing pad loses its effectiveness and no longer has uniform absorption, and the liquid discharged by the user cannot be absorbed by the nursing pad. If it is fully absorbed, it will also destroy the comfort of the nursing pad, and in severe cases, it will aggravate the user's condition

[0010] In addition, there is another urgent problem to be solved in the production of nursing pads: increasing the strength of the absorbent core of nursing pads

However, it is well known that adding glue to the absorbent core will greatly reduce the absorption capacity and speed of the absorbent core.
