Macro-Apertured Cleaning Substrate for Soil Removal and Liquid Transfer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cleaning substrates face challenges in effectively removing tough soils and managing liquid absorption on hard surfaces, particularly due to the limitations of thin apertured thermoplastic films and high basis weight nonwovens, which hinder efficient dirt removal and liquid transfer.
Innovation Solution
A cleaning substrate with a macro-apertured laminate of a thermoplastic formed film and a nonwoven layer, where the thermoplastic film is in direct contact with an absorbent layer, providing improved soil removal and liquid handling capabilities through a thickness of 0.5 mm to 1.5 mm, facilitating efficient fluid transport and preventing liquid re-wetting of the surface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If thin apertured thermoplastic films are used as the surface layer, then liquid transport capability is improved, but tough soil removal capability deteriorates
Solution Approach 1:
The surface layer is divided into two distinct components: a thermoplastic formed film providing liquid transport pathways and a nonwoven layer providing soil removal capability. This segmentation allows each component to optimize its specific function without compromising the other.
Solution Approach 2:
The invention uses a composite laminate structure combining thermoplastic formed film and nonwoven layer. This composite material approach integrates the liquid transport properties of the film with the mechanical soil removal properties of the nonwoven, achieving both functions simultaneously.

3Reliability
If the surface layer thickness is increased to improve soil removal, then soil removal capability is improved, but liquid transfer efficiency deteriorates
Solution Approach 1:
Different regions of the surface layer have different properties: the thermoplastic formed film regions provide liquid transport pathways with appropriate thickness for efficient transfer, while the nonwoven regions provide soil removal capability. This local quality differentiation resolves the contradiction between thickness and liquid transfer efficiency.
