Problems solved by technology

[0003] Existing sanitary products have a planar structure, but due to the special physiological structure of the human body, sanitary products cannot fit the body, so when the user lies on his side, it is easy to leak from the side; in particular, the absorption layer of the existing sanitary products mainly relies on SAP, And SAP liquid absorption needs certain time, when liquid (note: the liquid mentioned in the present invention includes but not limited to menstrual blood, urine) amount is big, if liquid can not be absorbed rapidly by SAP (absorbent layer), then be easy to Flow on the surface of sanitary products, causing side leakage
[0004] After the core of disposable sanitary care products absorbs liquid, it will produce hot and humid moisture. If the moisture cannot be discharged in time, it will make the user feel uncomfortable
At present, the existing disposable sanitary care products on the market basically use breathable bottom film to discharge moisture, but because the core body is mainly piled up with fluff pu...

Embodiment 1

[0041] like figure 1 As shown, a core for rapid absorption of sanitary products adopts a multi-layer diversion design (the existing disposable sanitary products usually adopt a layer diversion design, and only one diversion is completed). According to the characteristics of the human body, it is subdivided In order to realize the function of each layer, through the special layered design, the liquid flow and penetration to the lower part of the core are accelerated in four steps. The core structure of the present invention includes a drainage layer 1 , an acceleration layer 2 , a drainage layer 3 and an absorption layer 4 from top to bottom.

[0042]The function of the drainage layer 1 is to guide the liquid to permeate directly to the bottom of the core. The drainage layer 1 is located in the middle of the core body. In order to adapt to the characteristics of the human body, the drainage layer 1 has a width of 20-27mm and a length of 70-140mm. The material of the drainage ...

Embodiment 2

[0068] Others are as shown in Embodiment 1, the difference is: as Figure 4 As shown, the form of prefabricated guide grooves in the absorbing layer is that guide grooves are arranged around the core body, while no guide grooves are prefabricated in the middle of the core body, and the guide grooves are arranged according to the size of the guide grooves. Figure 4 It is a schematic diagram of several guide groove arrangements selected according to the diversion velocity of the present invention, super large guide groove arrangement 4-1, larger guide groove arrangement 4-2, slightly larger guide groove arrangement 4-3, large guide groove arrangement 4-4, Lesser guide grooves are arranged 4-5, and small guide grooves are arranged 4-6.

Abstract

The invention discloses a core body used for rapid absorption of sanitary products. The core body includes an accelerating layer, a flow guiding layer and an absorption layer from top to bottom. The accelerating layer contains short wood pulp fibers, the absorption layer contains long plant fibers, and the area of the accelerating layer is smaller than that of the absorption layer. By arranging the accelerating layer and the flow guiding layer, an 'instantaneous absorption and slow release' buffering moisture-retention mechanism is provided for liquid before the liquid enters the absorption layer, the absorption time of the absorption layer is prolonged, the liquid absorption contact surface is increased, and the technical effects of improving the absorption performance of the absorption layer and preventing side leakage are achieved.

Description

technical field [0001] The invention belongs to the field of absorbent pads, and in particular relates to a core body used for sanitary products, a manufacturing method and a guide groove prefabricated mold wheel. Background technique [0002] Disposable sanitary care products will have side leakage, hot and humid stuffiness, agglomeration, faults and other phenomena during use. These phenomena are closely related to the core structure and core production method of disposable sanitary care products. [0003] Existing sanitary products have a planar structure, but due to the special physiological structure of the human body, sanitary products cannot fit the body, so when the user lies on his side, it is easy to leak from the side; in particular, the absorption layer of the existing sanitary products mainly relies on SAP, And SAP liquid absorption needs certain time, when liquid (note: the liquid mentioned in the present invention includes but not limited to menstrual blood, u...
