Description

Convex dry leak-proof absorbent product

Technical Field

Background

At present, common absorbent products mainly comprise a surface layer, a diversion layer, a core body and a leakage-proof bottom layer, and have the problems of low absorption speed, large reverse osmosis quantity or easy leakage. In order to improve dryness and leakage resistance, the absorbent articles on the market currently do the following treatments:

(1) Increasing the dosage of the super absorbent resin (SAP), locking menstrual blood by the water-retaining property of the SAP, and preventing rewet; but the dosage of SAP is more, the product cost is increased, the overall flexibility of the product is deteriorated, and excessive SAP content also easily causes the damage or deformation of the base film in the production process, thereby bringing the hidden trouble of leakage of the base film. The requirements on leak resistance and absorbability are difficult to meet by adjusting the dosage and the proportion of SAP, and particularly the problems of low absorption speed, large rewet amount and high product leakage risk can occur when the pure cotton surface layer is matched;

(2) The cotton core grinding wheel with the grooves is used or the cotton core grinding wheel with the size is used, the dosage of SAP is increased at the convex part of the core body, in order to strengthen the absorption force of the middle part, but the whole cotton core product is thicker, and the requirements of women on comfort such as thinness, ventilation and the like cannot be met;

(3) The middle convex core is matched with the bottom core or the middle convex core is clamped between the upper and lower layers of cores; the dryness of the product can be improved to a certain extent, and the heavy feeling of the convex part can be reduced. But the absorption speed of the product is slow, and menstrual blood is intensively distributed at the convex part through the diffusion and conduction action of the single flow guide layer, so that the menstrual blood is difficult to diffuse well at the bottom core body, and the absorption speed of the product can be influenced;

the treatment mode in the step 3 can influence the use effect of the absorbent product, so that the convex dry and comfortable leak-proof absorbent product is provided, and has the characteristics of leak prevention, comfort and dryness.
