Textile Processing with Dehumidified Ozone to Prevent Color Defects
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing textile processing systems face challenges in achieving large batch processing without creating color inhomogeneities or defects when treating textiles with ozone, as increased production capacity often leads to unwanted staining and uneven bleaching.
Innovation Solution
A system comprising a textile processing machine integrated with a dehumidification system that reduces the humidity of the gaseous ozone mixture, preventing the formation of water droplets and controlling reactivity, thereby maintaining uniform treatment across large batches.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a large batch of textiles is processed in the ozone treatment apparatus to increase production capacity, then productivity increases, but color inhomogeneities and defects appear on the textiles
Solution Approach 1:
The patent applies parameter changes by controlling the humidity of the gaseous mixture within a specific range (20-80% relative humidity) to prevent water droplet formation while maintaining effective ozone treatment. This parameter optimization allows large batches to be processed without the color inhomogeneities that previously occurred, thus resolving the contradiction between productivity and manufacturing precision
Solution Approach 2:
The patent implements feedback control through sensors that continuously monitor humidity levels and ozone concentration in the treatment chamber. The system automatically adjusts operational parameters based on real-time measurements, ensuring uniform treatment across large batches and preventing defects while maintaining high production capacity
2Device complexity
If the gaseous mixture humidity is not controlled during ozone treatment, then the processing is simpler, but water droplets form causing stains and defects on textiles
Solution Approach 1:
The patent introduces a dehumidification system as an intermediary component between the ozone generation system and the textile treatment chamber. This intermediary controls moisture levels in the gaseous mixture, preventing water droplet formation that would cause stains, while integrating seamlessly into the existing apparatus without significantly increasing operational complexity
Solution Approach 2:
The patent changes the humidity parameter of the gaseous mixture to a controlled range (20-80% relative humidity) that prevents condensation and water droplet formation. This parameter optimization eliminates the harmful effect of water droplets while maintaining simple and effective processing operations
