Cellulose Nanofiber Deodorant Layer for Absorbent Articles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
General solid deodorants lack adhesiveness, requiring fixing means like hot melt adhesives or pressure-sensitive adhesives to secure them on absorbent articles, which increases costs and reduces contact efficiency with odors.
Innovation Solution
Incorporating a cellulose nanofiber layer directly onto the liquid impervious resin film of absorbent articles, allowing it to contact odors without additional adhesives, enhancing adhesiveness and odor absorption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a fixing means such as hot melt adhesive or pressure-sensitive adhesive is used to secure the deodorant substance, then the deodorant substance is securely fixed to the absorbent article, but the cost increases and contact efficiency between deodorant particles and odor is reduced
Solution Approach 1:
The cellulose nanofiber layer serves itself by providing both the fixing function and the deodorant function. The nanofibers naturally adhere to the liquid impervious resin film without requiring additional adhesives, while simultaneously providing numerous contact points for odor molecules to interact with the deodorant substance embedded within the layer.
Solution Approach 2:
The invention creates a composite structure where cellulose nanofibers are combined with deodorant substance to form a cellulose nanofiber layer. This composite material integrates the fixing capability of the nanofiber network with the odor-absorbing capability of the deodorant substance, eliminating the need for separate adhesive layers.
2Reliability
If a fixing means such as hot melt adhesive or pressure-sensitive adhesive is used to secure the deodorant substance, then the deodorant substance is securely fixed to the absorbent article, but the cost increases
Solution Approach 1:
The cellulose nanofiber layer serves itself by providing both the fixing function and the deodorant function. The nanofibers naturally adhere to the liquid impervious resin film without requiring additional adhesives, while simultaneously providing numerous contact points for odor molecules to interact with the deodorant substance embedded within the layer.
Solution Approach 2:
The invention uses cellulose nanofibers, which are derived from inexpensive cellulose sources, to create a disposable deodorant layer that eliminates the need for expensive adhesive materials. The nanofiber network itself provides the fixing mechanism, reducing material costs.
3Object-generated harmful factors
If a cellulose nanofiber layer is attached directly to the liquid impervious resin film without adhesive, then contact efficiency with odor is improved, but the layer may detach
Solution Approach 1:
The cellulose nanofiber layer serves itself by providing both the fixing function and the deodorant function. The nanofibers naturally adhere to the liquid impervious resin film without requiring additional adhesives, while simultaneously providing numerous contact points for odor molecules to interact with the deodorant substance embedded within the layer.
Solution Approach 2:
The invention changes the physical parameters of the deodorant substance by embedding it within a cellulose nanofiber matrix. This structural transformation allows the layer to attach directly to the liquid impervious resin film through the natural adhesiveness of the nanofibers, eliminating the need for additional adhesives while maintaining attachment reliability.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The cellulose nanofiber layer effectively reduces odors by physical adsorption, improving contact efficiency and odor reduction without increasing costs, while maintaining a soft texture and reducing odor diffusion.
Implementation Method 1
the cellulose nanofiber layer has an effect of physically adsorbing an odor to reduce the odor
Data Source
AI summary
An absorbent article that improves contact efficiency between a deodorant substance and an odor. The problem is solved by an absorbent article including an absorber and a liquid impervious resin film covering an outside of the absorber, in which a cellulose nanofiber layer is attached directly to a member outside the liquid impervious resin film, and the cellulose nanofiber layer can come into contact with an odor in an atmosphere outside the absorbent article.
