Soil Release Polymer Coating for Allergen-Repellent Textiles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Common laundry methods are insufficient to substantially remove and/or neutralize allergens such as animal dander and house dust mite allergens from textiles, leading to increased allergy reactions in consumers.
Innovation Solution
A fabric treatment composition comprising a polymeric soil release agent that promotes repellency of allergens from textiles by creating a coating that prevents allergens from adhering to the fabric, reducing their retention and attraction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If common laundry methods are used, then cleaning performance is maintained, but allergen removal and neutralization is insufficient
Solution Approach 1:
The patent introduces a fabric treatment composition as an intermediary substance that contains polymeric soil release agents and other functional components. This composition mediates between the textile and allergens, creating a protective layer that prevents allergen adherence and facilitates their removal during washing, thereby improving both allergen removal and neutralization effectiveness
Solution Approach 2:
The fabric treatment composition is a composite formulation combining multiple ingredients including polymeric soil release agents, surfactants, and other functional compounds. This composite approach allows the composition to simultaneously achieve cleaning, softening, and allergen repellency functions that individual substances cannot accomplish alone
2Object-affected harmful factors
If polymeric soil release agents are used, then allergen repellency is improved, but composition complexity increases
Solution Approach 1:
The polymeric soil release agents in the composition serve multiple functions simultaneously: they provide traditional soil release properties for fabric cleaning, create a protective coating that repels allergens, and contribute to fabric softening. This multi-functionality allows the composition to achieve allergen repellency without requiring separate specialized additives, thereby managing complexity
3Object-affected harmful factors
If fabric treatment composition is applied repeatedly, then allergen repellency is enhanced, but loss of substance increases
Solution Approach 1:
The composition is designed to be applied at controlled dosages where partial action is sufficient to achieve the desired allergen repellency effect. The polymeric soil release agents form effective protective layers at optimized concentrations, preventing the need for excessive application that would lead to unnecessary substance loss while maintaining enhanced repellency over repeated use cycles
