Description
Technical Field
The utility model belongs to the technical field of disposable absorption articles for use. More particularly, relates to a degradable sanitary towel and a sanitary product based on a double-layer pure cotton core.
Background
Most sanitary napkins on the market at present mainly comprise a surface layer (chemical fiber materials or blended materials, common cotton materials), a core layer (wood pulp wrapped by toilet paper), and an anti-leakage bottom layer (PE film) from the structural point of view. During the use process, the absorption speed and the liquid locking capacity of the absorbent greatly influence the experience of users. From the perspective of safety and health, the user is in a wet state for a long time due to poor permeation effect and air permeability, and is easy to cause bacterial infection to cause diseases. Statistics show that a woman experiences a 60-day menstrual period a year, and approximately 480 sanitary napkins are needed a year, calculated as 10 g of a sanitary napkin, so that about 960 ten thousand tons of garbage is generated by 20 million women a year. The existing disposable sanitary napkins have various styles, but the structure and the functional design of the sanitary napkins are all focused on the aspects of absorption, leakage prevention and no-clean, the face and the bottom materials mostly adopt PE films and chemical fibers, the sanitary napkins are difficult to degrade after being used, and the pollution of combustion treatment is large. Therefore, on the premise of meeting the requirements of people on the performances of the sanitary towels and the protection pads, the degradable disposable sanitary towels are produced and used, and the degradable disposable sanitary towels also provide a green living environment for human beings.
Chinese patent publication No. CN207912832U discloses a degradable sanitary napkin, which comprises a sanitary napkin main body, and the sanitary napkin main body comprises, from top to bottom, a polylactic acid fiber nonwoven fabric layer, a wood pulp or dust-free paper absorption core layer, and a degradable corn bottom film layer. The sanitary towel structure integrates the advantages of polylactic acid fiber products and degradable materials of the corn basement membrane, reduces the use of petrochemical raw materials and the damage of wastes to the environment to a certain extent, but the sanitary towel with the structure has some defects: 1) the polylactic acid fiber non-woven fabric layer is used as a surface layer, and the polylactic acid fiber non-woven fabric layer can be wet and percolated after meeting body fluid, has poor permeability and is uncomfortable to use; the permeability is not good enough, and inflammation is easy to generate. 2) The polylactic acid fiber non-woven fabric surface layer product has the defects of not soft hand feeling and large brittleness.
In addition, the disordered distribution of the high polymer materials in the core of the existing sanitary towel has some hidden troubles: 1) the macromolecule water-absorbing resin of the absorption core body is mostly glued on the upper and lower isolation layers, the upper and lower isolation layers are obvious, and therefore, after the core body meets menstrual blood, the upper macromolecule water-absorbing resin rapidly expands to cause gel blockage, and the secondary absorption speed is seriously influenced; 2) after the high polymer material close to the water permeable surface layer absorbs water and expands, the subsequent infiltration of menstrual blood is influenced, so that the menstrual blood flows transversely on the surface of the sanitary towel main body to generate leakage; 3) the high molecular water-absorbent resin material has leakage risk.
