Problems solved by technology

These odors can cause discomfort to the wearer and caregiver of the absorbent article
[0003] As the prior art for removing such unpleasant odors, deodorants such as silica gel or bentonite clay are directly impregnated with excrement. In the case of porous deodorants, the surface of the deodorant is covered with the above-mentioned excrement, and deodorization cannot be fully performed. function, that is, there is a problem of low deodorization effect
For example, cyclodextrin has a deodorizing function due to its small particle size and the inclusion of odorous substances in the surrounding area. However, in the state before use, the cyclodextrin includes the compounds in the air due to the moisture in the air, resulting in a decline in the deodorization function.
Moreover, cyclodextrin is easy to fall off from absorbent articles when used alone
The deodorizing function cannot be fully exerted, that is, there is a problem of low deodorizing effect
In addition, although it is also disclosed that the powder of cyclodextrin is fixed on an absorbent article using a polymer as a binder, the absorbent article becomes hard, impairing its feel.
[0004] Although many sanitary napkins with anti-odor function have been disclosed in this area, most of them are soaked in liquid medicine by non-woven fabrics, and then used for sanitary napkins, such as Chinese patent application CN200820028805.7, long-term use of this sanitary napkin is harmful to the human body. Health damage and poor deodorization effect

Abstract

The invention provides an absorbent product containing a tea polyphenol deodorization composition. The absorbent product containing the tea polyphenol deodorization composition comprises a liquid-permeable top sheet, an absorbent core and a basement membrane from top to bottom, wherein the absorbent core comprises the tea polyphenol deodorization composition. The invention has the beneficial effects that the absorbent product has a multidimensional smell control action on the basis of traditional absorption characteristics; tea polyphenol is coated by cyclodextrin, so that the stability of the tea polyphenol is enhanced, and the influence of the color of the tea polyphenol to the absorbent product is also avoided.

Description

technical field [0001] The invention relates to an absorbent product, in particular to an absorbent product containing a tea polyphenol deodorant composition. Background technique [0002] Absorbent articles such as disposable diapers, sanitary napkins, etc. are commonly used to absorb body fluids such as urine, feces, vaginal discharge, menstrual blood. In absorbing these fluids, absorbent articles contain a number of volatile compounds including fatty acids (such as isovaleric acid), sulfur-containing compounds (such as mercaptans and sulfides), ammonia, amines (such as triethylamine), ketones (such as 4 -heptanone), alcohols and aldehydes (decyl aldehyde), which cause unpleasant odors that can be emitted by these products during wear or disposal of absorbent articles. Once the fluid has been absorbed into the absorbent article, these compounds may be present in bodily fluids or evolved through chemical reactions and / or fluid degradation mechanisms. Additionally due to c...
