Core body used for rapid absorption of sanitary products, manufacturing method of core body and guide groove prefabricated die wheel

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...

AI Technical Summary

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 pulp and SAP, the core body has a high density, and most of the moisture cannot pass through the core body. bottom film, so this cannot effectively solve the problem of dampness and airtightness

[0005] In the prior art, in order to speed up the absorption speed of the core of disposable sanitary care products, there are technologies such as punching holes in the core of disposable sanitary care products and making gaps on the core of disposable sanitary care products. After these technologies are implemented, once The absorption rate of the core of disposable hygiene care products will indeed increase significantly, but it is undeniable that the strength of the core of disposable hygiene care products is damaged, and after absorbing liquid, it is easy to appear agglomeration and faults. bring great inconvenience to users

Moreover, the plant fiber in the core of the disposable sanitary care product may overflow from the holes or gaps in the core of the disposable sanitary care product, which brings potential safety hazards to users.
