Disposable absorption article

Abstract

Disclosed is a disposable absorption article containing the super absorption polymer and the control agent formed by the cyclodextrin and the peculiar smell masking or / and the function substance preventing the skin infection that are wrapped in the empty cavity of the cyclodextrin molecules. The peculiar smell masking or / and the function substance preventing the skin infection are one kind or a plurality of kinds among the hydrophobic compound or / and mixture having the deodorization, aroma, antibacterial action, anti-allergy and cooling functions that are suitable for being wrapped in the empty cavity of the cyclodextrin molecules. In the super absorption polymer and the mixture of the control agent, the weight ratio of the control agent to the mixture is zero point one percent to fifteen percent, the optimized is eight percent to twelve percent, the more optimized is nine percent to eleven percent. And the super absorption polymer and the mixture of the control agent are added with proper dispersant and antibacterial agent having the performance of water-solubility or dispersibility. The invention can effectively and reliably provide the peculiar smell control or / and skin infection preventing functions, and can facilitate the making and can be packaged and staraged by the normal means.

Description

technical field [0001] The invention relates to a disposable absorbent article for absorbing human excrement, especially a disposable absorbent article containing microcapsules composed of cyclodextrin-embedded odor-masking or / and skin infection-preventing functional substances, which can effectively and reliably Provide odor control and / or skin infection prevention functions, and can be conveniently manufactured and packaged for storage in the usual way. Background technique [0002] Known disposable absorbent articles, such as sanitary napkins, pantiliners, diapers, etc., have a liquid-permeable topsheet, a liquid-impermeable backsheet, and an absorbent body wrapped between the topsheet and the backsheet. Disposable absorbent articles can absorb body fluids such as menstruation and urine excreted by the wearer, thereby providing effective and comfortable body care for the wearer. For disposable absorbent articles, an important aspect of research and development is how to ...

AI Technical Summary

Problems solved by technology

Specifically: First, some of the effective chemical components contained in the above-mentioned functional substances are prone to failure, and are easy to deteriorate due to the effects of high temperature, high humidity, and radiation in the external environment.

Second, some of the effective chemical components contained in the above-mentioned functional substances are volatile. In order to prevent these volatile substances contained in disposable absorbent articles from volatilizing and losing during storage, abnormally sealed packaging must be used, which increases the difficulty of manufacturing. and cost

Third, the above-mentioned functional substances usually have the best effect when the disposable absorbent article is first used. With the prolongation of wearing time and the increase of the body fluid stored in the disposable absorbent article, the effective chemical components of the above-mentioned functional substance gradually decrease, and the effect Deterioration, that is to say, difficulty in maintaining stable, consistent performance when the disposable absorbent article is worn continuously

Fourth, the above-mentioned functional substances have different physical forms and contain different chemical components, and combining them into the surface layer and / or absorbent body of disposable absorbent articles usually requires different processes and methods, causing trouble and inconvenience during manufacture. inconvenient

Fifth, when different types of functional substances are added to disposable absorbent articles at the same time in order to obtain the joint effect of odor control and skin infection prevention, the functional substances are likely to interact with each other during storage and destroy or weaken their respective efficacy

However, there is no suggestion in the prior art that cyclodextrin inclusion compounds are used in disposable absorbent articles
