Description
Technical Field
The utility model relates to the field of absorbent sanitary products, in particular to a quick-suction grooved sanitary towel for improving the strength of a core body.
Background
With the economic development and the improvement of the living standard of people, consumers have higher and higher demands for sanitary products, and sanitary towels used in different scenes are increasingly subdivided, so that products with high absorption speed, dryness, no residue on the menstrual blood surface and ventilation are pursued. For sanitary napkins, absorbency is certainly the most important property, and if menstrual blood cannot be absorbed in time, it is extremely likely to cause back leakage or side leakage, and even dirty clothes or bedsheets, causing embarrassment. In addition, the requirements of consumers on the functionality and the comfort of the sanitary towel are higher and higher, and through investigation, the attention of consumers on the air permeability is higher, so that light, thin and breathable sanitary towel products are more and more favored by consumers.
Most of sanitary towel absorbent cores on the market today are long strips with uniform thickness, and as the absorption of menstrual blood by the absorbent core is diffused from the middle to the front and back and on the two sides, the core in the middle often becomes saturated and overflows, but cotton in the front and back parts is not fully absorbed, and a convex structure is arranged in the middle part of the absorbent core, so that the part has stronger absorption capacity. However, due to such a design, most of menstrual blood is accumulated in the middle part and is difficult to diffuse effectively, so that the middle part of the absorber is deformed, broken, hard and agglomerated due to the excessive menstrual blood absorbed, and the dryness and comfort level are not kept.
Some products are provided with diversion trenches on the skin-friendly surface layer, and groove lines are pressed out of the skin-friendly surface layer by mechanical pressing to the skin-friendly surface layer, so that the effect of preventing side leakage is achieved. However, the prior diversion trench structure has shallow groove lines, so that the side leakage prevention effect is poor, and the side leakage can occur. The utility model aims to solve the technical problems of low absorption speed and easy deformation of the core body after being soaked, and finally fault occurrence in the prior art.
