Cleaning cloth comprising an absorbent nonwoven material and method of manufacture
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cleaning cloths lack sufficient absorption and sliding properties, especially on rougher surfaces such as floors and wooden surfaces, which affects their cleaning efficiency and usability.
Innovation Solution
A cleaning cloth made from a flat, non-woven material comprising a mixture of absorbent natural fibers and synthetic melt-binding fibers, with an embossed surface and a partial abrasive coating, enhancing absorption and sliding properties while maintaining strength and durability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a full-surface coating is applied to increase cleaning power, then cleaning effectiveness is improved, but sliding properties deteriorate
Solution Approach 1:
The patent applies a partially coated surface design where coating is applied only to specific areas rather than the entire surface. This creates local zones of enhanced cleaning power while leaving other areas uncovered to maintain sliding properties, directly resolving the contradiction between cleaning effectiveness and ease of operation.
2Quantity of substance
If absorbent natural fibers are used to increase liquid storage capacity, then absorption is improved, but strength and durability worsen
Solution Approach 1:
The patent creates a composite fiber structure combining absorbent natural fibers (cotton, cellulose) with synthetic reinforcing fibers (polyester, polypropylene). This composite material achieves both high liquid storage capacity from the natural fibers and adequate strength for wiping applications from the synthetic fibers, resolving the contradiction between absorption and durability.
3Ease of manufacture
If a flat smooth surface is used to maintain simplicity, then manufacturing is easier, but sliding properties on rough surfaces deteriorate
Solution Approach 1:
The patent transitions from a flat two-dimensional surface to a three-dimensional textured surface with raised and recessed areas. This dimensional change creates micro-structures that enhance sliding properties on rough surfaces while maintaining manufacturing feasibility through conventional texturing techniques applied during the nonwoven fabric production process.
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 solution provides improved cleaning performance, enhanced sliding properties, and increased durability, making it suitable for various surfaces including rougher floors and wooden surfaces, while being cost-effective and environmentally friendly due to its high renewable and biodegradable material content.
Implementation Method 1
They can be brought into a molten and (partially) flowable state by the influence of heat, which enables partial embedding and bonding of other fibers.
