Solution Overview
Problem
Existing printers struggle to achieve excellent printing quality on mixed textiles, as traditional inks may not adequately satisfy the dyeing requirements of multiple textile materials, leading to poor color expression and adhesion issues.
Innovation Solution
A printer equipped with an inkjet type printhead and an adhesive head unit that sprays a multicomponent adhesive, allowing for digital printing on textiles, including mixed textiles, by forming a design on a transfer film and then transferring it to the textile using the adhesive.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If traditional inks are used for printing on mixed textiles, then the printing process is simple, but the dyeing quality and adhesion are poor
Solution Approach 1:
The printing system is segmented into multiple independent printheads, each dedicated to a specific ink type (reactive ink for cotton, acid ink for silk, sublimation ink for polyester). This segmentation allows each printhead to be optimized for its specific ink type while maintaining overall system simplicity through modular architecture.
Solution Approach 2:
The printing system achieves universality by incorporating multiple printheads that can handle different ink types within a single device. This multi-functional design enables the printer to adapt to various textile materials (cotton, silk, polyester, and their mixtures) without requiring separate printing systems for each material type.
2Manufacturing precision
If a single ink type is used for mixed textiles, then the device complexity is low, but the color expression and adhesion are insufficient
Solution Approach 1:
The ink system is segmented into multiple independent ink delivery channels, each supplying a specific ink type to its corresponding printhead. This segmentation enables precise control over ink application for each textile fiber type present in the mixed fabric, ensuring optimal color expression and adhesion.
Solution Approach 2:
The system applies local quality by directing specific ink types to specific areas or layers of the textile based on the local fiber composition. Each printhead deposits its ink type selectively, ensuring that cotton areas receive reactive ink, polyester areas receive sublimation ink, and so on, thereby optimizing color expression for each local region.
3Productivity
If digital printing method is used, then productivity and flexibility are improved, but the ability to handle mixed textiles is limited
Solution Approach 1:
The digital printing system achieves universality by integrating multiple printheads capable of handling different ink types within a single digital printing platform. This multi-functional design maintains the high productivity and flexibility of digital printing while expanding adaptability to handle various textile materials including cotton, silk, polyester, and their mixtures.
Solution Approach 2:
The system employs dynamic control where the digital printing controller selectively activates specific printheads based on the detected textile material composition. This dynamic adaptation allows the printer to maintain high-speed digital printing operations while automatically adjusting which ink types are applied to match the specific textile material being printed.
