Description

Core capable of enhancing flow guiding performance

Technical Field

The utility model relates to an absorb liquid and use the health supplies field, especially relate to a core that can strengthen water conservancy diversion performance.

Background

The core is an important component of sanitary napkins, baby diapers or adult diapers, and is mainly used for absorbing and containing liquid and keeping the surface layer of the core contacting with human bodies relatively dry so as to enhance the comfort of users.

Most of the traditional cores are long-strip light thin bodies, after liquid such as urine falls on the surface of the core, the urine is freely and disorderly diffused in the core and gradually absorbed, when the liquid amount is large and the liquid discharge speed of a human body is greater than the absorption speed of the core, the possibility of overflowing the core exists in the liquid, the contact time of the human body and the liquid is prolonged, and discomfort or skin anaphylactic reaction is brought to a user.

SUMMERY OF THE UTILITY MODEL

In order to overcome the not enough of prior art, the utility model provides a can strengthen water conservancy diversion performance's core, it enables a large amount of liquid and gets into fast and hold in the guiding gutter, avoids liquid to spill over, reduces the contact time of human body and liquid, reinforcing travelling comfort.

The utility model provides a can strengthen water conservancy diversion performance's core, includes rectangular form core main part, the core main part is provided with the polymer absorbent resin layer that is used for absorbing liquid including the first substrate layer, second substrate layer, the third substrate layer that set gradually between two adjacent substrate layers, the wherein two at least sides of core main part are relative court the central line direction of core main part is folding, and is in form the guiding gutter in the core main part has the guiding gutter the upper surface of core main part is provided with the precoat for reinforcing the travelling comfort and preventing that the particulate matter in the polymer absorbent resin layer from dropping outside the core main part.

Furthermore, the four side edges of the core body are folded towards the center line direction of the core body, and the flow guide groove is formed in the core body.

Furthermore, the diversion trench is a rectangular groove with an accommodating space, the rectangular groove can be naturally formed after four sides of the core body are folded, the core body is simple and convenient to use, the accommodating space is large, and the rectangular groove can be well adapted to the position of the urination or defecation part of a human body.

Furthermore, the fabric layer, the first substrate layer, the second substrate layer and the third substrate layer are sheet-shaped non-woven fabrics, which are also called non-woven fabrics, needle punched cottons and the like, and are formed by oriented or random fibers, the non-woven fabrics are called as cloth due to the appearance and certain properties of the cloth, and the non-woven fabrics have the characteristics of moisture resistance, ventilation, flexibility, light weight, no combustion supporting, easy decomposition, no toxicity, no irritation, rich colors, low price, recycling and the like, are generally produced by a continuous one-step method by taking polypropylene granules as raw materials and carrying out high-temperature melting, spinning, line laying and hot-pressing coiling, and can also be made of other suitable materials according to actual needs; the local area of precoat and first substrate layer adhesive bonding are in the same place, increase fastness and planarization, avoid bulging etc. adopt local area and first substrate layer adhesive bonding to be in the same place, not only can reduce the use amount of material, also avoid influencing the imbibition performance.

The utility model has the advantages that: the core body is folded towards the center line direction of the core body at least two opposite side edges of the core body, and the core body is provided with the diversion trench, so that a large amount of liquid can rapidly enter and be contained in the diversion trench, the liquid is prevented from overflowing, the contact time of a human body and the liquid is reduced, and the comfort is enhanced; the upper surface of the core body with the diversion trenches is provided with a fabric layer for enhancing comfort and preventing particles in the high-molecular water-absorbent resin layer from falling outside the core body, and the core body is safe and sanitary.

Detailed Description

The following describes the present invention with reference to the accompanying drawings. It should be noted that the description of the embodiments is provided to help understanding of the present invention, but the present invention is not limited thereto. In addition, the technical features related to the embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.

Referring to fig. 1-3, a core capable of enhancing flow conductivity comprises a strip-shaped core main body 1, wherein the core main body 1 comprises a first substrate layer 2, a second substrate layer 3 and a third substrate layer 4 which are sequentially arranged, and the first substrate layer 2, the second substrate layer 3 and the third substrate layer 4 are made of sheet-shaped non-woven fabrics or other suitable materials; a high polymer water-absorbing resin layer 5 for absorbing liquid is arranged between two adjacent substrate layers and is composed of a plurality of high polymer water-absorbing resin particles, the high polymer water-absorbing resin is called SAP for short, is a typical functional high polymer material, can absorb hundreds of times of liquid of the weight of the high polymer water-absorbing resin layer, and has strong water retention capacity, so the high polymer water-absorbing resin layer is also called super absorbent or high water retention agent; in the first embodiment, two of the long sides of the core body 1 are folded toward the center line direction of the core body 1, and a diversion trench 6, specifically a rectangular groove with a receiving space, is formed on the core body 1; a fabric layer 7, which may be a sheet-like non-woven fabric or other suitable material, is disposed on the upper surface of the core body 1 having the flow guide grooves 6; local area and the bonding of first substrate layer 2 of precoat 7 link together for outside reinforcing travelling comfort and preventing that the particulate matter in the polymer water-absorbent resin layer 5 from dropping core main part 1, increase precoat 7 back, guiding gutter 6 has been sealed, and liquid can enter into guiding gutter 6, and some polymer water-absorbent resin granule can only drop in guiding gutter 6, but can not shift out outside core main part 1, can not with human direct contact, clean health and safety.

Referring to fig. 4 again, in the second embodiment, a cut 8 of about 45 degrees may be cut at four corners of the core body 1, and then the four sides of the core body 1 are folded toward the center line of the core body 1, and the diversion trench 6 is formed on the core body 1, in this way, a closed or relatively closed diversion trench 6 may be formed, so as to prevent the liquid from overflowing out of the core body 1 when the amount of the liquid is large.

The two implementations of the utility model can form the diversion trench 6, and increase the area for absorbing liquid after being folded; after folding like three-layer core main part 1, except guiding gutter 6 department, other parts Beijing has become six layers to can also realize very good absorption effect under the less condition of the number of piles of original core main part 1, directly handle as wasting the material after having solved the tradition and tailor four sides of core main part 1 simultaneously, and lead to extravagant problem.
