AI Technical Summary
Existing technologies make it difficult to accurately identify critical abrupt change regions in the digital inkjet printing process of bio-based nylon fabrics, leading to uneven slurry distribution, ink edge diffusion, or localized thermal deformation of the fabric, which affects the stability of printing quality.
By constructing a material sensitivity index and performing multi-physical characteristic coupling calculations by combining fluid and thermal characteristic terms, the tendency for critical abrupt changes is quantified. Furthermore, by coupling the boundary risk index with equipment operating parameters, a safety correction coefficient is generated to perform smooth damping correction on the sizing parameters, ensuring that the parameters operate within the safe process window.
It significantly improves the clarity of printed patterns and the consistency of color reproduction, reduces the probability of uneven sizing and fabric thermal deformation, and achieves stability and repeatability of digital inkjet printing on bio-based nylon fabrics.
