Solution Overview
Problem
Current textiles lack durable antimicrobial properties, leading to contamination and infection transmission in various environments, and existing methods for disinfection are either ineffective or damage the fabric, while also being resource-intensive in terms of water and detergent usage.
Innovation Solution
A textile treatment using a combination of quaternary ammonium organosilane compounds, silver chloride, Poly-glucosamine, and biocoated silver particles, applied through methods like padding, coating, or spraying, to create a wash-durable, antimicrobial fabric that inhibits bacterial, viral, and fungal growth, while also incorporating additional functional treatments for multifunctionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional washing methods are used to clean textiles, then textiles can be cleaned, but water and detergent consumption increases and washing time extends
Solution Approach 1:
The textile is pre-treated with antimicrobial and hydrophobic coatings during manufacturing, so that stains and microbes are prevented from adhering strongly in the first place. This preliminary protective action reduces the effort and resources needed during subsequent washing operations.
Solution Approach 2:
The hydrophobic coating enables the textile to repel water and stains automatically without requiring intensive washing. The antimicrobial coating allows the textile to resist microbial growth self-sufficiently, reducing the need for frequent heavy washing cycles and thereby conserving water and detergent.
2Reliability
If textiles are treated with antimicrobial agents, then microbial contamination is reduced, but wash durability decreases and agents leach out
Solution Approach 1:
The patent combines multiple antimicrobial agents (silver particles, zinc oxide, titanium dioxide) with hydrophobic coating materials to create a composite treatment layer. This composite structure anchors the antimicrobial agents more securely to the textile fibers, preventing leaching during washing while maintaining antimicrobial activity. The multi-component system provides both durability and sustained effectiveness.
Solution Approach 2:
The antimicrobial agents are applied to form a localized coating layer on the textile surface rather than penetrating deeply into the fabric. This surface-localized treatment ensures the agents remain accessible to microbes while the hydrophobic matrix provides structural integrity and wash durability. The concentrated local application maintains high effectiveness at the interface where microbial contact occurs.
3Object-affected harmful factors
If intensive washing is performed to remove stains and microbes, then cleaning effectiveness improves, but textile damage increases
Solution Approach 1:
The hydrophobic coating creates a preliminary barrier that prevents stains and microbes from strongly adhering to the textile fibers. This preliminary anti-adhesion action means that during washing, less mechanical force is required to remove contaminants, thereby protecting the textile from damage. The coating essentially pre-prevents the harmful attachment that would otherwise require aggressive washing to remove.
4Quantity of substance
If textiles remain untreated, then resource consumption is low, but microbial growth and infection transmission increase
Solution Approach 1:
The treated textile provides self-service protection against microbial contamination through the integrated antimicrobial and hydrophobic coatings. The antimicrobial agents actively inhibit microbial growth, while the hydrophobic surface prevents moisture accumulation that would otherwise promote microbial proliferation. This self-protective capability reduces the need for resource-intensive washing and disinfection operations.
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 treated textiles exhibit significant reduction in microbial contamination, maintain effectiveness through repeated wash cycles, and reduce washing costs by being mildly hydrophobic and non-leaching, providing enhanced protection and performance.
Implementation Method 1
a combination of one, several or all of a quaternary ammonium organosilane compound, and/or silver chloride and/or other types of silver salts, and/or Poly-glucosamine, and/or propiconazole, and/or biocoated silver particles and/or poly-hexa-methylene-biguanide (herein after referred to also as 'functional agents'), that the entire cross section of the substrate becomes antimicrobial, anti fungal and anti viral in nature
Implementation Method 2
