Solution Overview
Problem
Current printers struggle to achieve excellent printing quality on mixed textiles, as existing inks fail to provide both vivid color expression and strong adhesion, leading to durability issues and limitations in digital printing methods.
Innovation Solution
A printer equipped with an ink head unit for spraying CMYK and white inks, along with an adhesive head unit capable of mixing different adhesive materials to form a multicomponent adhesive, allowing for digital printing on textiles, paper, or transfer films, including mixed textiles, while maintaining the texture and ensuring high-quality prints.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a single-type ink (reactive ink or transfer ink) is used for mixed textiles, then the printing process is simple, but the dyeing quality and adhesion are insufficient
Solution Approach 1:
The ink system is segmented into multiple independent ink types (reactive ink for cotton, transfer ink for synthetic fibers, adhesive ink for bonding). Each ink type targets specific fiber materials, allowing the printer to handle mixed textiles by applying appropriate inks to appropriate regions without compromising adhesion or dyeing quality.
Solution Approach 2:
The invention uses a composite ink system combining multiple ink types with different chemical properties. By layering reactive ink, transfer ink, and adhesive ink in specific sequences, the system achieves both vivid color expression and strong adhesion on mixed textiles, resolving the contradiction between simple process and high reliability.
2Productivity
If digital printing method is used for mixed textiles, then productivity and design flexibility are improved, but adhesion and color vividness deteriorate
Solution Approach 1:
The digital printing system dynamically adjusts ink selection, ink composition, and printing parameters based on real-time detection of textile material composition. This allows the system to maintain high productivity and design flexibility while adapting ink formulations and layering strategies to ensure optimal adhesion and color vividness for each specific textile type.
Solution Approach 2:
The invention changes multiple parameters including ink type selection, ink concentration, printing speed, and layering sequence based on textile material detection. By dynamically adjusting these parameters, the system maintains digital printing advantages while achieving reliable adhesion and vivid colors on mixed textiles.
3Reliability
If adhesive is applied to entire film surface, then adhesion is improved, but the texture of textile is lost and process complexity increases
Solution Approach 1:
The adhesive application process uses local quality by applying adhesive only to specific regions where design elements are printed, rather than the entire film surface. This is achieved through precise digital positioning and selective inkjet deposition, maintaining textile texture in non-design areas while ensuring adequate adhesion in design areas, thereby reducing process complexity.
