Description

Novel soft absorption core

Technical Field

The utility model belongs to the technical field of absorption cores, and particularly relates to an absorption core of a paper diaper.

Background

The existing paper diaper absorbing core body has 2 structures, one is a core body structure formed by combining crushed wood pulp and granular high-molecular water-absorbing resin on line, the other is a core body structure formed by combining high-gram-weight fluffy cloth and granular high-molecular water-absorbing resin, the upper layer and the lower layer of the core body structure use spunlace non-woven fabrics or hydrophilic spun-bonded non-woven fabrics or dust-free paper and the like, and the outer layer of the core body structure uses hydrophilic spun-bonded non-woven fabrics for wrapping. However, the water-absorbent polymer resins used in these two absorbent cores are solid polymers in the form of small particles, which results in a strong granular feel to the touch of the entire core and poor overall flexibility.

The utility model discloses a novel adult diaper with the publication number of CN209864318U, which comprises a surface non-woven fabric layer, an absorption core body and a leakage-proof bottom film which are sequentially stacked from top to bottom, wherein an isolation layer is arranged on the upper surface of the surface non-woven fabric layer at a position corresponding to the buttocks of a human body, a plurality of hydrogel particles are arranged on the surface of the isolation layer at intervals, a wound care film is formed by spraying chitosan wound-protecting biological dressings on the surface of the isolation layer and the hydrogel particles, and release paper is arranged on the surface of the wound care film. The novel adult diaper has the effects of stopping bleeding and preventing the wound from being adhered to the diaper. However, the hydrogel particles are granular, and the hydrogel particles are only separated from the skin of the buttocks by the release paper, so that the problems that the core body has strong granular feeling and the wearer is uncomfortable still exist.

SUMMERY OF THE UTILITY MODEL

The technical problem to be solved by the utility model is the problems of strong granular feeling and uncomfortable wearing of the core body of the paper diaper mentioned in the background technology. And uniformly spraying an acrylic acid monomer and a cross-linking agent solution on the fluffy cloth, catalyzing the acrylic acid monomer on the fluffy cloth, and uniformly adsorbing the water-absorbing gel formed by catalysis on the fluffy cloth to form the required water-absorbing gel fluffy cloth composite material. And then covering the non-woven fabric on the composite material to obtain the novel soft absorption core body. The core has high softness, no granular feeling, and high water absorption.

It is an object of the present invention to provide a new flexible absorbent core.

In order to achieve the purpose, the utility model provides the following technical scheme:

a novel soft absorption core body comprises a water-absorbing gel fluffy cloth layer and a first non-woven fabric layer, wherein the water-absorbing gel fluffy cloth layer is formed by uniformly absorbing water-absorbing gel inside and outside the fluffy cloth layer, and the two surfaces of the water-absorbing gel fluffy cloth layer are covered with the non-woven fabric layers. The fluffy cloth is uniformly adsorbed with the water-absorbing gel inside and outside and is prepared by uniformly spraying acrylic acid monomer and cross-linking agent solution on the fluffy cloth, the fluffy cloth has stronger diversion effect, and the water-absorbing performance of the core body is enhanced by the acrylic acid gel with strong liquid absorption. And the softness of the fluffy cloth adhered with the gel is not reduced, and the fluffy cloth has no granular feeling of the high molecular water-absorbent resin. The non-woven fabric has the characteristics of moisture resistance, air permeability, flexibility, light weight, no combustion supporting, easy decomposition, no toxicity or irritation, rich colors, low price, recycling and the like. The core mainly separates gel (urine) and makes skin comfortable.

Preferably, the core body further comprises a second non-woven fabric layer wrapping the first non-woven fabric layer. The hydrophilic spunbond wrapping layer can be used to secure the core structure against shifting of the core layer.

Preferably, the first nonwoven fabric layer is a hydrophilic spun-bonded nonwoven fabric, a spunlace nonwoven fabric or a dust-free paper, and the nonwoven fabric has high moisture absorption and air permeability.

Preferably, the gram weight of the second nonwoven fabric layer is 8-15 gsm. The cloth is appropriate in thickness and comfortable to wear.

Preferably, the gram weight of the first nonwoven fabric layer is 20-30 gsm. The cloth is appropriate in thickness and comfortable to wear.

Preferably, the water-absorbing gel fluffy cloth layer covers the first non-woven fabric layer, the second non-woven fabric layer is wrapped on the first non-woven fabric layer, and the covering or wrapping is completed through an online composite process.

Wherein, preferably, the fluffy cloth layer of absorbent gel be rectangular lamellar body, circular lamellar body or oval lamellar body. The diaper pants are suitable for various types in various specifications.

The utility model has the following beneficial effects:

(1) the novel soft absorption core body is provided with the water absorption gel fluffy cloth layer, so that the softness of the core body is improved and the granular sensation of the core body is reduced on the premise of not reducing the absorption performance.

Drawings

Figure 1 is a cross-sectional view of a novel flexible absorbent core of example 1 of the present invention.

In the figure, 1 is a water-absorbent gel fluffy cloth layer, 2 is a first non-woven cloth layer, and 3 is a second non-woven cloth layer.

Detailed Description

The present invention will be described in detail below with reference to the accompanying drawings and examples.

Example 1:

the drawings are for illustrative purposes only and are not to be construed as limiting the patent; for the purpose of better illustrating the present embodiments, certain elements of the drawings may be omitted, enlarged or reduced, and do not represent the size of an actual product; it will be understood by those skilled in the art that certain well-known structures in the drawings and descriptions thereof may be omitted. The positional relationships depicted in the drawings are for illustrative purposes only and should not be construed as limiting the present patent.
