Problems solved by technology

[0002] With the development of the economy and the improvement of living standards, people have more and more consumer demand for disposable sanitary products. The main structure of sanitary napkins is composed of a surface layer, an absorbent core and an anti-seepage bottom film. The role of contact and conduction of menstrual blood, and through the study of female physiological structure, it is found that the use of sanitary napkins with the same overall thickness will not be compact, which will easily cause menstrual blood to flow to both sides of the sanitary napkin during tides, resulting in the risk of side leakage. Due to poor fit, consumers often pull their underwear upwards, making the sanitary napkin close to the private parts, resulting in an unnatural feeling when wearing, and poor comfort. In order to solve the problem of physiological fit, some manufacturers have developed a sanitary napkin. Centered absorbent core, but since this absorbent core accounts for more than 60% of the product by weight, if you want to produce a centered effect, the fluff pulp used should be increased by at least 30%, and the fluff pulp is made of natural trees after processing Therefore, in addition to causing a large increase in cost, this method is not conducive to environmental protection, green energy saving and carbon emission reduction

Abstract

The invention discloses a double-layer fabric sanitary napkin, which comprises a sanitary napkin main body, and the double-layer fabric sanitary napkin is composed of a double-layer fabric layer, a drainage layer, an absorbent core body, a base film, a backing glue and a backing release paper from top to bottom. The double-layer fabric layer is composed of a surface layer, a joint portion and a central surface layer in order from the bottom to the top, so that a partial double-layer structure surface layer is formed on the sanitary napkin main body, a certain height difference is generated inthe middle portion of the double-layer fabric layer, after the combination product is produced, in addition to maintaining the softness, conductivity and absorption capacity, the product's applicability is greatly improved, so that the comfortableness, side leakage and dryness during usage can be improved, the product can reduce the use of pure cotton materials, and it is beneficial to green economy, environmental protection and carbon emissions.
