Allergen Denaturing Agent Coating for Cabin Filters
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing aqueous compositions for textiles, particularly cabin filters in motor vehicles, face challenges in ensuring a homogeneous and long-lasting anti-allergen function due to uneven distribution and high flow rates, making them impractical and ineffective.
Innovation Solution
An aqueous coating composition combining an allergen denaturing agent (AdA) with a compatibilizing agent, such as polyphenols-based compounds and functional silanes, to maintain flexibility and facilitate even application on non-woven fibers, ensuring sustained anti-allergen properties.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an allergen denaturing agent is applied on a textile, then the anti-allergen function is provided, but the composition cannot be distributed homogeneously over the entire structure of the textile
Solution Approach 1:
A compatibilizing agent is introduced as an intermediary substance between the allergen denaturing agent and the textile fibers. This compatibilizing agent facilitates homogeneous distribution of the allergen denaturing agent across the textile structure while maintaining the anti-allergen function. The compatibilizing agent acts as a bridge that enables uniform impregnation without compromising the denaturing capability.
Solution Approach 2:
The invention uses a composite composition combining the allergen denaturing agent with a compatibilizing agent. This composite material approach allows the allergen denaturing agent to be carried uniformly on the textile fibers through the compatibilizing agent, achieving both homogeneous distribution and sustained anti-allergen activity.
2Reliability
If a known composition made from an allergen denaturing agent is used, then the anti-allergen treatment is provided, but the composition has a high flow rate which makes the application complex and ineffective
Solution Approach 1:
The compatibilizing agent serves as a mediator that modifies the flow characteristics of the allergen denaturing agent composition. By introducing this intermediary substance, the composition achieves appropriate viscosity and flow properties that facilitate easy and effective application while maintaining the anti-allergen treatment functionality.
3Reliability
If the composition is applied on the textile, then the anti-allergen function is provided, but the anti-allergen property cannot be guaranteed over time
Solution Approach 1:
The compatibilizing agent acts as a carrier and stabilizing intermediary that ensures long-term retention of the allergen denaturing agent on the textile. This intermediary substance prevents premature degradation or washing off, guaranteeing the anti-allergen property over an extended service life.
Solution Approach 2:
The composite composition of allergen denaturing agent and compatibilizing agent creates a stable system that maintains anti-allergen activity over time. The synergistic interaction between the two components ensures sustained performance and longevity of the anti-allergen property on the textile.
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 composition provides a flexible and homogeneously impregnated coating with extended anti-allergen service life, effectively inhibiting allergen activity and improving application ease on textiles, suitable for various applications including cabin filters and medical equipment.
Implementation Method 1
at least one compatibilising agent of said at least one AdA. Surprisingly, the compatibilising agent of said at least one AdA interacts favourably with the latter. Indeed, it has been observed that the compatibilising agent makes it possible to maintain flexibility of the AdA such that the coating obtained by means of the composition according to the invention has a suitable flexibility.
Implementation Method 2
The denaturing agent is capable, as indicated by its name, of denaturing the activity of the allergen by binding itself to the latter for the purpose of modifying the three-dimensional structure thereof so as to inhibit the activity thereof.
