Multilayer Textile Wipe for Uniform Cleaning Liquid Release
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wiping cloths with multi-layer designs fail to ensure even application and uniform cleaning results due to uneven distribution of cleaning agents, with previous solutions like microcapsules being sensitive to pressure and causing streaks, and lacking controlled liquid release.
Innovation Solution
A multi-layered wiping cloth with a textile material structure where the wiping and cleaning layer and storage layer are mechanically connected over a large area through pierced fiber strands, allowing for uniform liquid transport and reactivation of a dryable cleaning agent with water addition.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If microcapsules containing cleaning agent are used, then cleaning agent can be released upon water addition, but the microcapsule material impairs cleaning quality through streak formation and the capsules break under mechanical load
Solution Approach 1:
The cleaning agent is extracted from microcapsule structures and integrated directly into the textile fibers through impregnation. This eliminates the microcapsule wall material that causes streaking while preserving the controlled release mechanism through water-activatable chemistry bound to the fibers.
Solution Approach 2:
The textile structure with its natural porosity and fiber network replaces the microcapsule containment approach. The porous textile allows uniform water distribution and cleaning agent release without the structural constraints and failure modes of microcapsules under mechanical stress.
2Productivity
If multi-layer material structure is used, then cleaning and storage functions are separated, but uneven distribution of cleaning agent results occurs
Solution Approach 1:
The cleaning agent is impregnated throughout the entire multi-layer textile structure during manufacturing, merging the cleaning function uniformly across all layers. This ensures consistent agent distribution and uniform cleaning performance across the entire wipe surface.
Solution Approach 2:
The textile structure is designed to simultaneously provide mechanical durability, liquid absorption, and cleaning agent containment across all layers. Each layer contributes to multiple functions, ensuring uniform performance throughout the multi-layer construction.
3Duration of action of moving object
If cleaning agent is impregnated in storage layer, then controlled liquid release is achieved, but cleaning agent distribution becomes uneven
Solution Approach 1:
The textile is divided into functional layers with distinct roles: the wiping layers provide immediate cleaning action while the storage layer provides controlled liquid release. The cleaning agent is distributed according to these segmented functions, achieving both controlled release and uniform distribution.
Solution Approach 2:
Different layers are impregnated with cleaning agent according to their specific functional requirements. The storage layer receives agent for controlled release over time, while wiping layers receive agent for immediate cleaning action, optimizing both duration and distribution uniformity.

AI summary
The invention relates to a wipe which has a multilayer design and has at least two material layers lying directly one over the other, a first outer material layer forming an outer wiping and cleaning layer and a second material layer being designed as a retaining layer. The aim of the invention is to provide such a wipe which promotes a constant application of cleaning liquid over a stationary surface. According to the invention, this is achieved in that the at least two material layers lying one over the other are made of textile materials preferably having at least approximately the same suction or water dispensing capability; the surface of the wiping and cleaning layer and the surface of the retaining layer are mechanically connected together; and a cleaning agent which can be reactivated by the addition of water is provided in at least one of the material layers lying one over the other.
