Fishing Net Thread Composition for Single-Process Color Variation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for varying the color of fishing nets along the widthwise direction are time-consuming and labor-intensive, requiring multiple dyeing processes and increasing production costs.
Innovation Solution
The method involves forming sections of the fishing net with threads having different dyeing properties, such as varying polymer types or copolymerization ratios, allowing for simultaneous dyeing of sections in different colors or densities using a single dye process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If sections of the fishing net are dyed separately with different dyes to achieve color variation in the widthwise direction, then color diversity is improved, but production time and labor increase significantly
Solution Approach 1:
The patent applies local quality by incorporating threads with different dyeing properties at specific locations (different sections) of the fishing net. Each section contains threads designed to absorb dye differently, allowing a single dyeing process to produce color variations across the width of the net without requiring separate dyeing operations for each section.
Solution Approach 2:
The patent changes the parameter of thread dyeing properties by using threads with different polymer types or copolymerization ratios. This parameter change enables different sections of the net to absorb the same dye differently, achieving color variation through material composition rather than process complexity.
2Adaptability or versatility
If multiple dyeing processes are used to achieve different colors in different sections, then color differentiation is improved, but production cost increases
Solution Approach 1:
The patent merges multiple dyeing operations into a single dyeing process. By combining the color differentiation function into the thread material itself rather than requiring separate dyeing steps, the manufacturing process is simplified and costs are reduced while maintaining color differentiation capability.
3Productivity
If threads with different dyeing properties are used in different sections, then single-process color variation is achieved, but thread selection complexity increases
Solution Approach 1:
The patent segments the fishing net into different sections, each containing threads with specific dyeing properties tailored to that section's requirements. This segmentation allows the complex thread selection to be organized into manageable sections rather than requiring complex control during the entire dyeing process.
