Printing machine and method for printing textiles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing textile printing machines struggle to apply precise and sharp-contoured print motifs on three-dimensional fabric structures, often resulting in bleeding of inks and reduced durability of the printed design.
Innovation Solution
A printing machine with a pressing means arranged between the priming and printing stages, which applies a primer to the textile and then presses the motif region to flatten it, allowing for precise digital printing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a print motif is applied directly onto the three-dimensional fabric structure of the textile, then the printing process is simple, but the print motif lacks precision and contour sharpness
Solution Approach 1:
The patent applies a primer to the textile fabric before the actual printing process. This preliminary action prepares the surface by filling the three-dimensional fabric structure, creating a smoother base that enables precise print motif application with sharp contours while maintaining a manageable process complexity
2Manufacturing precision
If a primer is applied to the textile before printing, then the print motif precision improves, but the printing process time increases
Solution Approach 1:
The patent combines the primer application and the actual print motif application into a single printing operation using the same print head. This merging of operations allows the primer to be applied during the printing process itself, thereby improving print motif precision without significantly increasing the overall printing process time
3Reliability
If printing is performed on the three-dimensional fabric structure without pretreatment, then the process is efficient, but ink bleeding occurs and durability decreases
Solution Approach 1:
The patent applies a primer as a preliminary treatment before the actual printing. This primer penetrates and fills the fabric structure, creating a stable base that prevents ink bleeding and enhances print motif durability, while the integrated application method maintains printing efficiency
4Manufacturing precision
If the three-dimensional fabric structure is flattened before printing, then print motif precision improves, but additional processing steps are required
Solution Approach 1:
Instead of physically flattening the fabric structure through separate mechanical processing, the patent applies a primer that chemically fills and smooths the three-dimensional fabric structure. This preliminary chemical action creates a flattened surface suitable for precise printing without requiring additional mechanical processing steps
