Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for imparting microbicidal properties to textiles using nanomaterials face challenges such as nanoparticle agglomeration, the need for reducing agents and binders, and the difficulty of maintaining functionality and colorfastness, especially during washing, which limits their industrial application and aesthetic appeal.
Innovation Solution
A method for manufacturing functional textile products with microbicidal activity that involves sublimation printing followed by impregnation with nanoparticulate metal oxide materials, using a reducing agent-free process to ensure durability and high-definition image retention without chemical fixatives, allowing the nanoparticles to penetrate and remain stable on the fabric.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If nanomaterials are incorporated into textile substrates to provide microbicidal functionality, then the antimicrobial properties are improved, but nanoparticle agglomeration occurs and reduces manufacturing precision
Solution Approach 1:
The patent applies preliminary action by conducting sublimation printing before nanoparticle impregnation. The print is transferred to the textile substrate first, then nanoparticles are applied in subsequent steps. This sequence ensures that the printing process is not interfered with by nanoparticle presence, while nanoparticles can still provide their microbicidal function, thereby resolving the contradiction between functionality and manufacturing precision.
2Reliability
If reducing agents and binders are used to fix nanoparticles on textiles, then the microbicidal properties are improved, but the complexity of the manufacturing process increases
Solution Approach 1:
The patent extracts and eliminates the need for reducing agents and binders from the conventional nanoparticle application process. By using physical impregnation methods such as padding, printing, or coating followed by drying, the process achieves nanoparticle fixation without requiring additional chemical substances, thereby reducing process complexity while maintaining microbicidal functionality.
3Reliability
If conventional nanoparticle impregnation methods are used, then microbicidal properties are achieved, but colorfastness and image quality deteriorate during washing
Solution Approach 1:
The patent applies preliminary action by completing the sublimation printing process before applying nanoparticles. This ensures that the print is already fixed on the textile substrate through the sublimation process, which creates a durable bond. Subsequent nanoparticle application does not affect the already-fixed print, thereby maintaining colorfastness and image quality during washing while preserving microbicidal properties.
4Reliability
If chemical fixatives are used to maintain nanoparticle stability, then the microbicidal functionality is improved, but the aesthetic appeal and image clarity are reduced
Solution Approach 1:
The patent extracts and eliminates the use of chemical fixatives from the nanoparticle application process. Instead, it relies on physical methods such as padding, printing, or coating followed by drying to achieve nanoparticle fixation. This approach avoids chemical residues that could interfere with sublimation printing and degrade image clarity, while still providing stable microbicidal functionality.
