Three-Layer Textile for Passive Microplastic Collection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for removing microplastic debris, particularly microfibers, from water bodies are limited to industrial-scale solutions and do not provide accessible options for consumers, while microplastics pose significant environmental and health risks.
Innovation Solution
A textile with three distinct layers - an inner water-resistant layer, a middle high-pile layer for attraction, and an exterior mesh layer for capture - designed to passively collect microplastic debris as it is worn or used in water, utilizing ultrasonic welding for construction to enhance efficiency and reduce production time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If industrial-scale methods are used to remove microplastics from water, then removal effectiveness is improved, but accessibility to consumers deteriorates
Solution Approach 1:
The textile enables consumers to perform microplastic collection themselves through passive wear during water activities. The garment automatically collects microplastics on its own without requiring active consumer intervention, making the industrial-scale effective solution accessible to individual consumers through self-service application
Solution Approach 2:
The invention divides the large-scale microplastic collection task into individual, wearable units that consumers can use personally. By segmenting the collection function into discrete textile products, the solution becomes accessible to consumers while maintaining effectiveness through cumulative collection across multiple users
2Ease of operation
If passive collection textile is worn during water activities, then consumer effort is reduced, but collection efficiency must be maintained
Solution Approach 1:
The textile performs the collection function automatically while being worn, eliminating the need for active consumer effort. The garment's structure and materials enable it to self-collect microplastics through its interaction with water, maintaining productivity without requiring consumer intervention
Solution Approach 2:
The textile employs composite material structures with multiple layers having different properties optimized for passive collection. The combination of materials enables effective microplastic capture while the textile moves through water, maintaining collection efficiency without active effort from the consumer

AI summary
A textile and a method of making the same comprising a microplastic collection layer, a microplastic capture layer, and a water resistant protection layer. The microplastic collection outer layer includes a plurality of openings therein for collecting microplastics from a body of water. The microplastic attraction and capture middle layer attracts and captures the microplastics collected by the microplastic collection outer layer. The water resistant protection layer protects a wearer's skin against the microplastics captured by the microplastic attraction and capture middle layer.
