Non-Woven Elastomer Wrap for Absorbent Article Disposal Roll Retention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing absorbent articles face challenges in maintaining a rolled-up state during disposal due to insufficient fixation, particularly when using flexible materials for the exterior body, leading to potential exposure of the absorbing pad.
Innovation Solution
A post-treatment material comprising a non-woven fabric layer with a density of 15 kg/m3 to 120 kg/m3 and a resin layer with an elastomer layer, bonded via ultrasonic or thermal welding, providing a band shape with foldable structures for effective fixation and holding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a flexible material is used for the exterior body to ensure satisfactory touch, then the touch quality is improved, but the fixation capability of the absorbent article in a rolled-up state deteriorates
Solution Approach 1:
The post-treatment material is divided into distinct functional layers: a non-woven fabric layer providing flexibility and touch quality, and a resin layer providing fixation capability. This segmentation allows each layer to optimize its specific function without compromising the other.
Solution Approach 2:
The invention uses a composite structure combining non-woven fabric and resin materials with different properties. The non-woven fabric ensures satisfactory touch while the resin layer provides the necessary fixation strength, resolving the contradiction between softness and fixation capability.
2Ease of operation
If a flexible material is used for the exterior body to maintain softness, then the comfort is improved, but the fixation strength of the post-treatment tape deteriorates
Solution Approach 1:
The post-treatment material is divided into distinct functional layers: a non-woven fabric layer providing flexibility and comfort, and a resin layer providing fixation capability. This segmentation allows each layer to optimize its specific function without compromising the other.
Solution Approach 2:
The invention uses a composite structure combining non-woven fabric and resin materials with different properties. The non-woven fabric ensures satisfactory touch while the resin layer provides the necessary fixation strength, resolving the contradiction between softness and fixation capability.
3Ease of operation
