Problems solved by technology

These odors can cause discomfort to the wearer and caregiver of the absorbent article
[0003] Absorbent paper is an important part of absorbent products and constitutes the absorbent core of absorbent products. It mainly plays the role of absorbing menstrual blood, but usually absorbent paper is only absorbent and has no effect on removing odors. Absorbent materials are mainly responsible for odors. Produced after absorbing body fluids such as urine, menstrual blood, etc.
[0004] In addition, after the current absorbent paper is cut into rolls, its two sides become open, causing the polymer water-absorbing resin and powdery or granular additives in the absorbent paper to fall off, resulting in the loss of absorption performance and efficacy of absorbent products.
In addition, in the use of consumers, the water-absorbing agent absorbs water and swells, and it is easy to shift from both sides, causing side leakage

Abstract

The invention provides peculiar smell-removal compound absorbent paper for absorbent sanitary products. The absorbent paper is of a four-layer laminar structure and comprises a smell control layer, an absorbent layer, an upper isolation layer and a lower isolation layer, wherein the smell control layer is arranged at the middle of the absorbent paper; the upper isolation layer and the lower isolation layer are respectively at both sides of the absorbent paper; and all layers are compounded together by adopting heat conglutinating or gluing. Compared with the prior art, both longitudinal sides are respectively provided with a sealing strip, thereby, absorbent granules and peculiar smell-removal control agent granules are effectively prevented from being sprinkled, and the phenomenon that an absorbent overflows after absorbing water to swell is prevented. The peculiar smell-removal compound absorbent paper for the absorbent sanitary products can be widely applied to absorbent products, such as sanitary napkins, diapers for babies or adults, mattresses or pet mats. The invention has the beneficial effects that the absorbent paper has a bacteriostatic action and a peculiar smell-removal action. When being used for producing functional sanitary napkins, the absorbent paper is simple in use and simplified in technological process.

Description

technical field [0001] The invention belongs to the field of women's hygiene products, and in particular relates to an odor-removing composite absorbent paper for absorbent hygiene products. 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 me...
