Silver Ion Dosing for Durable Antimicrobial Textile Washing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing antimicrobial treatments for fabrics and textiles are ineffective in providing lasting protection against microbial pathogens, leading to stain, odor, and the spread of infections, as they degrade over time and can immunize pathogens, making them untreatable with conventional methods.
Innovation Solution
A system for generating and diluting metallic ions, specifically silver, for use in commercial washing systems to treat textiles, involving a concentrate supply and dilution system with a dilution reservoir, dosing pump, and electronics control module to ensure consistent and controlled antimicrobial agent delivery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If antimicrobial agent is embedded in fabric during manufacturing, then initial antimicrobial efficacy is achieved, but efficacy degrades over time after washing
Solution Approach 1:
The patent applies the principle of discarding and recovering by removing the antimicrobial agent from the fabric inventory and recovering it through a washroom treatment system. The silver ion generator releases metallic ions during washing cycles, which are then deposited onto the fabric, effectively recovering the antimicrobial property after each wash instead of permanently depleting it
Solution Approach 2:
The system enables self-service by automatically generating and applying antimicrobial treatment during the normal washing process. The washroom system itself becomes the source of antimicrobial agent delivery, eliminating the need for separate treatment steps or manual intervention to maintain efficacy
2Reliability
If silver is embedded in fabric, then antimicrobial protection is provided, but fabric aesthetics and comfort deteriorate
Solution Approach 1:
The patent extracts the antimicrobial function from the fabric structure itself and relocates it to the washroom treatment system. By removing silver embedding from the fabric manufacturing process and replacing it with post-manufacturing ion generation treatment, the harmful aesthetic effects are eliminated while preserving the protective function
Solution Approach 2:
The system changes the physical state and concentration parameters of the antimicrobial agent. Instead of permanent embedding, metallic silver is converted to silver ions at controlled concentrations during washing, allowing effective antimicrobial action without the discoloration and discomfort associated with high concentrations of embedded silver
3Reliability
If fabric is impregnated with antimicrobial agent during manufacturing, then antimicrobial feature is provided, but inventory replacement cost increases
Solution Approach 1:
The system ensures continuity of useful action by continuously replenishing the antimicrobial agent during each washing cycle. Instead of the fabric permanently depleting its embedded silver and requiring replacement, the system continuously restores and maintains the antimicrobial concentration, extending the functional life of the fabric inventory
Solution Approach 2:
The system applies discarding and recovering by treating the loss of antimicrobial agent during washing not as permanent waste requiring inventory replacement, but as a recoverable resource. The silver ion generator recovers and reapplies the antimicrobial agent, transforming a consumable loss into a renewable cycle that reduces overall inventory replacement needs
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 system effectively transforms ordinary textiles into lasting antimicrobial entities by maintaining a consistent silver ion concentration, ensuring high antimicrobial efficacy even after multiple wash cycles, thereby preventing the spread of infections and reducing the need for frequent inventory replacement.

AI summary
An antimicrobial supply system employs a process water supply and incorporates a metallic ion supply connected to the process water supply to provide a high ion concentrate to an output. A dilution reservoir is connected to the metallic ion supply output and has an input from the process water supply. A pump is connected to an output of the reservoir. A manifold connected to the pump provides a dilute concentrate to at least one washing system. An electronics control module is connected to a first flow controller between the process water supply and the metallic ion supply and a second flow controller between the metallic ion supply and the reservoir for dilution control establishing a desired metallic ion concentration.
