Problems solved by technology

[0003] At present, sanitary napkins on the market have basic absorption capacity, but because such products are composed of multiple structures such as surface layer, absorbent layer and bottom film, the design limitations of each layer structure and improper material selection often lead to stuffy and uncomfortable when consumers use it. It is breathable and prone to side leakage, and it is easy to cause the growth of microorganisms under stuffy and humid conditions, all of which will have a negative impact on consumers' physical and mental health

Abstract

The invention discloses a sanitary towel. The sanitary towel comprises a fabric layer, a chip layer, a flow guiding layer, a breathable bottom film, release paper and a coating which are sequentially stacked from top to bottom. A structural adhesive is arranged between the adjacent layers, a main core body is arranged between the flow guiding layer and the breathable bottom film, a breathable gathering and distributing part with the closed boundary is arranged in the center of the main core body, the length of the breathable gathering and distributing part is at least 10% larger than that of the main core body, the width of the breathable gathering and distributing part is at least 20% larger than that of the main core body, and the depth of the breathable gathering and distributing part is at least 30% larger than the thickness of the main core body. Side leakage is reduced through the breathable gathering and distributing part, vent holes are formed in the main core body, through the combination of the breathable gathering and distributing part and the vent holes, besides enough absorption capacity is kept, the breathability of the product is greatly improved, meanwhile, secretion absorption can be accelerated to reduce side leakage risks, therefore, physical and psychological health of a customer is benefited, and the use comfort is improved.

Description

technical field [0001] The invention relates to a sanitary article, in particular to a sanitary napkin. Background technique [0002] With the development of the economy and the improvement of living standards, people's consumption demand for disposable sanitary products is increasing. At the same time, as consumption concepts become more mature and open, consumers hope to use products that are more comfortable, breathable and reassuring. [0003] At present, sanitary napkins on the market have basic absorption capacity, but because such products are composed of multiple structures such as surface layer, absorbent layer and bottom film, the design limitations of each layer structure and improper material selection often lead to stuffy and uncomfortable when consumers use it. It is breathable and prone to side leakage, and it is easy to cause microbial growth under stuffy and humid conditions, all of which will have a negative impact on consumers' physical and mental health....
