Biodegradable environment-friendly sanitary napkin

Abstract

The invention provides a biodegradable environment-friendly sanitary napkin. The biodegradable environment-friendly sanitary napkin comprises the components of a biodegradable surface layer, a dustfree paper packaged absorbent paper absorption core and a biodegradable base film; wherein the biodegradable surface layer, the dustfree paper packaged absorbent paper absorption core and the biodegradable base film are arranged from top to bottom. The materials of the surface layer and the base film are biodegradable, thereby eliminating an environment hazard of the sanitary napkin after use. The biodegradable environment-friendly sanitary napkin is an environment-friendly product.

Description

Technical field [0001] The invention belongs to the field of physiological hygiene products and relates to a biodegradable environmentally friendly sanitary napkin. Background technique [0002] The basic structure of a sanitary napkin is generally a top layer, an absorbent core and a bottom film. The top layer is mostly non-woven material, and the bottom film is mostly plastic film anti-permeability material. The top layer non-woven material has high wet strength and good softness. , has the characteristics of fast penetration speed, and the plastic film base film has the advantages of high strength, good softness, and strong anti-leakage. The characteristics of these materials make it suitable for use in sanitary napkins. However, during long-term use, some Problems, such as the surface non-woven material, which is mainly composed of polymer chemical synthetic fibers and adhesives, will cause the user to have uncomfortable reactions such as skin itching and allergies when ...

AI Technical Summary

Problems solved by technology

[0002] The basic structure of sanitary napkins is generally a surface layer, an absorbent core and a bottom film. The surface layer is mostly made of non-woven materials, and the bottom film is mostly made of plastic film impermeable materials. The surface layer of non-woven fabric material has high wet strength and good softness. , The characteristics of fast penetration speed, the plastic film bottom film has the advantages of high strength, good flexibility, and strong leakage resistance. The characteristics of these materials make it suitable for use in sanitary napkins, but in the long-term use process, some Problems, such as the surface layer of non-woven fabric materials are mainly composed of polymer chemical synthetic fibers and adhesives, when in contact with the user for a long time, it will cause discomfort reactions such as skin itching and allergies; and the plastic film bottom film also has poor air permeability. The problem

More attention should be paid to the fact that sanitary napkins are disposable products, and the environmental protection treatment after use is a big problem. The above-mentioned surface layer and bottom film materials are difficult to degrade, which will have a serious impact on the environment.
