Detailed Description
In all the examples of the present invention, the temperature and pressure are not particularly emphasized, and are both normal temperature and normal pressure, and the equipment use is not particularly described, and the equipment can be used according to the conventional setting.
A nursing sanitary towel of a plant polyphenol composite antibacterial system comprises a nursing surface layer, a dust-free paper layer, an antibacterial layer, an absorption layer, a dust-free paper layer, a PE (polyethylene) breathable film and a waterproof bottom layer from top to bottom in sequence.
The nursing surface layer comprises the following raw materials in parts by weight: 10-15 parts of persimmon peel extract, 10-15 parts of corncob extract, 5-10 parts of astragalus membranaceus and 5-10 parts of motherwort.
Persimmon has extremely high economic value, particularly persimmon peel, and related documents describe that various active substance components in persimmon peel, including carotenoid compounds, flavonoids, fatty acids, phenols, various amino acids, trace elements and the like, are widely used in the fields of medicines, health care, cosmetics and the like. Persimmon peel is a byproduct of persimmon deep processing, and is only partially used as food filler initially, and most of persimmon peel is wasted. In recent years, the medicinal value of the persimmon peel gradually draws the attention of researchers, but the comprehensive utilization rate of the persimmon peel in China is still very low so far, and the development work of the persimmon peel is still in the initial small-scale production stage. In the aspect of economic benefit, the persimmon peel extract containing polyphenol substances and pectin is extracted by an acid extraction method from the aspects of antibiosis, health care and peculiar smell removal of the sanitary towel, and the polyphenol substances are plant polyphenol. Plant polyphenols are classified into hydrolyzed tannins and condensed tannins according to the chemical structural characteristics of tannins. The ortho-position phenolic hydroxyl in the phenolic hydroxyl structure of the plant polyphenol is easily oxidized into a quinone structure, oxygen in the environment is consumed, and meanwhile, the plant polyphenol has strong capture capacity on free radicals such as active oxygen, so that the polyphenol has strong oxidation resistance and the capacity of eliminating the free radicals. Therefore, the plant polyphenol has certain antiviral, antiallergic, antioxidant and anti-inflammatory effects. The pectin in the persimmon peel has high medicinal value and nutritive value. Pectin can activate immune cells in vitro, and can also play a role in the immune system by regulating the secretion of immune factors, so as to maintain the body steady state, is an active substance with the function of immunoregulation, and has the functions of enhancing the activity of immune cells and resisting oxidation. Meanwhile, pectin molecules contain a plurality of polar groups such as-OH, -CO-and the like, which are easy to hinge into a net structure through the actions of hydrogen bonds, electrostatic bonding ionic bonds, covalent bonds and the like, have thickening and gelling effects, have good stability, are easy to cover on non-woven fabrics, and greatly promote the adhesion capacity of other raw materials of the nursing surface layer on the non-woven fabrics (compared with the prior art adopting traditional Chinese medicine bags), and the method is a great progress.
