Description

FIELD OF TECHNOLOGY

The present utility model relates to the production of paper diapers, in particular to an ultra-thin super absorbent baby diaper, which not only can quickly absorb urine, but also effectively prevents the leakage of urine, ensuring a favorable state of air penetration, while the thickness of the diaper is significantly reduced.

BACKGROUND

The paper diaper (CN 104997594 A) comprises a moisture resistant lower layer, a permeable surface layer and an absorbent middle layer between them, while the absorbent middle layer is wrapped with a covering layer, and a discharge layer is provided between the covering layer and the permeable surface layer. This paper diaper is characterized in that the discharge layer contains water-absorbing lining paper in the upper layer and the lower layer, and the middle of the discharge layer contains a complex substance of pulp from fine pile and aromatic salt. This paper diaper has the following disadvantages:

 1. poor air permeability, therefore, children's hot urine can easily cause allergies and eczema due to poor air permeability after putting on the diaper;

 2. due to the thick absorbent middle layer after putting on the diaper on the child, friction is created between the legs during walking, which directly affects the development of the shape of the child’s legs and the level of comfort;

 3. Adult diapers are difficult to wear due to the large thickness of the absorbent middle layer and poor breathability.

ESSENCE OF A USEFUL MODEL

The objective of the utility model: an ultra-thin super absorbent baby diaper developed on the basis of the existing technology, which not only can quickly absorb urine, but also effectively prevents urine from seeping, providing a favorable state of air penetration, while the thickness of the diaper is significantly reduced.

An ultra-thin super absorbent baby diaper comprises a baby diaper base, in which the inguinal region of the baby diaper base contains a surface layer, a high water absorbing SAF fibrous nonwoven fabric and an SMS non-woven salt-absorbing nonwoven fabric, with a high water absorbing SAF fibrous nonwoven layer between surface layer and neutralizing salt-soaked non-woven SMS.

The high water-absorbing fibrous nonwoven fabric (2) SAF may be a spunbond non-woven fabric with acrylic acid or a meltblown non-woven fabric with acrylic acid, or a hot-rolled non-woven fabric with acrylic acid, or a spunlace non-woven fabric with acrylic acid.

An ultra-thin super absorbent baby diaper may contain one or more layers of said SAF fibrous nonwoven fabric with high water absorption capacity with a layer thickness of less than 1 mm.

The surface layer may comprise a nonwoven fabric ES, or a nonwoven fabric SS, or a spunlace nonwoven fabric, or gauze, or a perforated plastic film.

An ultra-thin super absorbent baby diaper may contain one or more of the aforementioned layers of neutralizing salt-soaked non-woven SMS.

Salt-neutralizing non-woven SMS can have a gram-mass of 14-200 g / m ² .

Scheme of the structure adapted to achieve the specified task of the utility model.

1. A structure in which a layer of SAF fibrous nonwoven fabric (SAF ™ is a registered trademark of Super Absorbent Fiber, a highly absorbent fabric) is placed between the surface layer and the release resistant SMS water-repellent nonwoven fabric, is the first technical feature of this utility model . Such a structure has the following objectives: SAF has the most important functions such as high water absorption capacity, normal salt absorption capacity, hygroscopicity and the ability to absorb sweat. Since SAF material has a maximum water absorption capacity, 200 times greater than its own weight, maximum normal salt absorption capacity, 60 times greater than its own weight, and is an absolutely white and tasteless fibrous substance with high tensile strength; SAF nonwoven fabric is more convenient and safe than SAP (registered trademark of Super ABSORBENT powder, super absorbent powder), due to its ability to prevent the penetration of menstrual bleeding and the functions of quick drying, breathing, heat storage, etc., i.e. heat can be brought out, so a child wearing baby diapers feels good and comfortable, does not feel humidity. The thickness of the inguinal region of the baby diaper is reduced so that the baby in the diaper feels comfortable.

2. The structure in which the neutralizing salt-soaked nonwoven SMS is located on the back surface of the nonwoven with acrylic acid is the second technical feature of this utility model. Such a structure has the following objectives: since the amount of urine (or loose stool) cannot be determined, since it differs from person to person, it is always difficult to determine whether to choose a diaper with a high or low absorbency. If a diaper with high absorbency is selected, since the absorbent middle layer of the diaper is thick by itself, the diaper is clearly visible under the trousers, and the user often feels embarrassed and uncomfortable, especially in spring, summer and autumn; if a diaper with a low absorbency is selected, the diaper is invisible under the trousers, as it is thin, but with a lot of urine it often leaks a little and stains the trousers, especially light ones, and the trousers stained with urine lead to the inevitable embarrassment of the user. In this application, SAF fibrous nonwoven fabric with high water absorption capacity is located between the surface layer and SMS water-repellent non-woven fabric, resistant to discharge, so that the thickness does not increase significantly, the diaper is not visible under the trousers, the absorbent capacity of the diaper is fundamentally increased, and the user's needs are met .

3. The structure in which several layers of fibrous nonwoven fabric SAF with high water absorption capacity with a thickness of each layer of less than 1 mm are stacked, is the third technical feature of this utility model. This structure has the following purpose: when two or more layers of fibrous nonwoven fabric SAF with high water absorption capacity with a thickness of each layer of less than 1 mm are stacked in a stack, the thickness created by this stack prevents the leakage of urine from the upper layer so that the water absorption capacity of two or more layers of fibrous nonwoven fabric SAF with high water absorption capacity with a thickness of each layer of less than 1 mm significantly exceeds the water absorption capacity of one layer of equivalent thickness.

Technical solution: an ultrathin super-absorbent baby diaper contains a baby diaper base, in which the inguinal region of the baby diaper base contains a surface layer, high-absorbency fibrous non-woven fabric SAF and a layer of neutralizing non-woven SMS non-woven fabric, while a high-absorbent fiber nonwoven layer SAF the ability is placed between the surface layer and the layer of neutralizing salt-soaked nonwoven SMS.

Compared with the prior art, the ultra-thin super absorbent baby diaper disclosed in this utility model has the following advantages:

 1. SMS neutralizing salt-soaked non-woven fabric is located on the back surface of the breathable middle layer of the moisture retaining core so as to be waterproof, effectively prevent leakage, and significantly reduce the thickness of the baby diaper, while combining waterproof, discharge resistance, and breathability;

 2. SAF fibrous nonwoven fabric with high water absorption capacity serves as a layer of sanitary pad absorbing liquid, which not only significantly reduces the thickness of the sanitary pad, but also increases the ability of the baby diaper to absorb urine, providing the baby with comfort and satisfying the user's requirements.
