Abrasion-Resistant Textile Surface With Through-Colored Platelets
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Textile fabrics with high abrasion resistance and platelet-shaped elements are unable to retain printed motifs due to the rubbing off of paint layers, making it impossible to produce permanent color designs on these materials.
Innovation Solution
A textile fabric with a flexible substrate and platelet-shaped elements made of an abrasion-resistant material, where the color of the motif penetrates the entire height of the elements, ensuring the design remains permanent even with gradual abrasion, and using disperse dyes that form a permanent bond with the material, along with fillers and adhesives for enhanced mechanical stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If paint layers are applied to create motifs on textile fabrics with platelet-shaped elements, then color designs can be produced, but the paint layers are rubbed off after a very short time due to abrasion
Solution Approach 1:
The platelet-shaped elements are pre-colored during their manufacturing process before being applied to the substrate. This preliminary coloring action ensures that the color is permanently embedded in the abrasive elements themselves, eliminating the problem of paint layers being rubbed off during subsequent use.
Solution Approach 2:
The invention changes the parameter of color application timing from post-manufacturing (painting on finished fabric) to pre-manufacturing (coloring platelets before application). This parameter change transforms the color retention mechanism from surface coating to intrinsic material property.
2Ease of manufacture
If the substrate is colored to create motifs, then color designs can be achieved, but the color is not permanently retained because the substrate is mechanically exposed to abrasion
Solution Approach 1:
The invention applies color locally to the platelet-shaped elements rather than the entire substrate. The platelets that will be exposed to abrasion are pre-colored, while the substrate itself remains uncolored or minimally colored, creating a localized color protection strategy where color is concentrated in the protective abrasive layer.
3Reliability
If disperse dyes are used to penetrate platelet-shaped elements, then permanent color bonds are formed, but the process requires thorough penetration through the entire height of the elements
Solution Approach 1:
The invention changes the dyeing parameter from surface-level application to full penetration through the entire height of the platelet elements. Disperse dyes are selected specifically for their ability to penetrate and bond permanently with the platelet material, transforming the color application from a superficial process to a through-and-through impregnation process.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution allows for the creation of textile fabrics with high mechanical stability and permanent color retention, enabling detailed and high-quality motifs without the need for dyeing the substrate, while maintaining flexibility and abrasion resistance.
Implementation Method 1
The color or the colors for the motif can preferably be disperse dyes. These are able to diffuse into the material for the platelet-shaped elements and form a permanent bond with this material.
Implementation Method 2
The required mechanical stability of the fabric is generated by the fillers, with the fillers being able to be applied to the substrate with abrasion-resistant adhesion using the water-based dispersion adhesive.
