Laser Denim Finishing with Base Templates for Custom Wear Patterns
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The traditional process of producing jeans with wear patterns is resource-intensive, time-consuming, and environmentally costly, requiring significant water and chemical usage.
Innovation Solution
Laser finishing technology is introduced to create custom wear patterns on denim apparel by using fabric templates that can be washed with different base wash recipes and then processed with a laser to achieve various finishes, reducing the need for chemical oxidizers and abrasive particles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If traditional chemical and mechanical finishing processes are used to create wear patterns on jeans, then the desired faded and distressed appearance is achieved, but water consumption and chemical usage increase significantly
Solution Approach 1:
The patent replaces traditional mechanical finishing methods (sandblasting, pumice stones, abrasives) and chemical finishing methods (oxidizers, bleaches) with a laser-based system. The laser beam directly ablates the denim fabric to create wear patterns, eliminating the need for water-intensive washing processes and chemical treatments while achieving the same aesthetic effects.
Solution Approach 2:
The patent utilizes controlled variations in laser parameters (power, speed, pulse duration, wavelength) to achieve different wear pattern effects on denim. By adjusting these parameters, the system can create various degrees of fading, distressing, and texturing without requiring multiple chemical baths or mechanical processing steps, thereby reducing water and chemical consumption.
2Adaptability or versatility
If multiple traditional finishing processes are applied to create different wear patterns, then diverse jean styles are produced, but processing time and production costs increase
Solution Approach 1:
The laser finishing system serves as a universal tool that can create multiple types of wear patterns (fading, distressing, holes, whiskers, honeycombs, etc.) on denim garments through software-controlled beam modulation. A single laser machine with programmable patterns replaces multiple specialized finishing machines and processes, enabling diverse jean styles to be produced efficiently without increasing processing time.
3Ease of manufacture
If traditional finishing methods are used to create distressed looks, then the desired aesthetic effect is achieved, but environmental pollution and resource consumption increase
Solution Approach 1:
The patent replaces polluting mechanical and chemical systems with a clean laser-based ablation process. Traditional methods generate wastewater containing chemicals and suspended particles that require treatment, while the laser process produces minimal waste, primarily in the form of vaporized fabric material that can be captured and filtered, significantly reducing environmental pollution.
4Ease of manufacture
If conventional finishing processes are used to produce wear patterns, then traditional jean aesthetics are achieved, but the process is resource-intensive and costly
Solution Approach 1:
The patent substitutes resource-intensive mechanical and chemical finishing processes with a laser-based system that requires minimal consumables. The laser process eliminates the need for large volumes of water for washing and rinsing, chemical oxidizers and bleaches, pumice stones, and other abrasive materials, thereby dramatically reducing the quantity of substances consumed in wear pattern production.
