Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fabric dye production methods, particularly synthetic dyes, generate pollution and disrupt ecosystems due to chemical synthesis and resource availability issues with natural dyes, while also facing challenges in color reproduction and stability.
Innovation Solution
A method to produce dye from recycled textile waste materials, involving pulverization of previously dyed fibers to create a powder dye, which can be mixed to achieve desired colors, reducing environmental impact and adhering to eco-sustainability regulations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If synthetic dyes are produced using chemical synthesis, then color stability and consistency are improved, but environmental pollution increases
Solution Approach 1:
The patent applies the discarding and recovering principle by collecting textile waste materials that would otherwise be discarded and recovering the dye substances embedded in these fabrics. The process involves shredding, washing, and extracting dyes from used textiles, thereby converting waste into valuable dye resources while reducing environmental pollution and the need for new chemical dye synthesis.
2Object-generated harmful factors
If natural dyes are produced from plants, then environmental impact is reduced, but color reproduction consistency and stability deteriorate
Solution Approach 1:
The patent recovers dyes from actual used textile materials, which ensures that the extracted dyes have proven colorfastness and performance characteristics. This approach combines the environmental benefits of natural dye extraction with the reliability of dyes that have already been tested in real-world applications, overcoming the inconsistency issue of plant-based natural dyes.
Solution Approach 2:
The patent creates a reusable dye resource by copying the successful color properties from proven textile materials. Instead of relying on variable plant sources, the process replicates the effective dye characteristics already present in durable colored fabrics, ensuring consistent color reproduction while maintaining environmental sustainability.
3Productivity
If textile waste is recycled through pulverization, then resource efficiency is improved, but production process complexity increases
Solution Approach 1:
The patent implements a systematic process for recovering dyes from textile waste through shredding, washing, and extraction steps. While this involves multiple operations, each step is designed to be straightforward and build upon the previous one, transforming discarded textiles into reusable dye resources efficiently.
