Solution Overview
Problem
Ink jet pigment textile printing methods face challenges with color developability, particularly on polyester or polyester mixed fabrics, where ink permeation and sinking issues lead to poor color retention and unevenness.
Innovation Solution
A treatment liquid composition containing a cationic compound, a nonionic fluorine-based surfactant with an HLB value between 6 and 13, and resin particles is used to prevent ink permeation into the fabric, ensuring excellent color developability and uniformity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If ink jet pigment textile printing is performed on polyester or polyester mixed fabrics, then productivity and versatility are improved, but color developability deteriorates due to ink permeation and sinking into the fabric
Solution Approach 1:
The patent applies a treatment liquid containing fluorine-based surfactant and resin particles to the fabric surface before ink jet printing. This preliminary treatment creates a surface layer that prevents ink penetration, thereby improving color developability on polyester fabrics while maintaining versatility across different fabric types.
Solution Approach 2:
The treatment liquid acts as an intermediary between the ink and the fabric. The fluorine-based surfactant and resin particles in the treatment liquid form a mediating layer that controls ink interaction with the fabric, preventing unwanted penetration while allowing controlled color deposition.
2Manufacturing precision
If treatment liquid is used to physically fix pigment to fabric surface, then color developability is improved, but unevenness in color development occurs
Solution Approach 1:
The treatment liquid is formulated as a composite material containing fluorine-based surfactant, resin particles, and other components that work synergistically. The fluorine-based surfactant provides uniform surface activity while resin particles provide structured support, together preventing both penetration and unevenness.
Solution Approach 2:
The patent specifies precise parameter ranges for the treatment liquid components, including fluorine-based surfactant content (0.1-5 mass%) and resin particle concentration, to optimize both color developability and uniformity. These controlled parameters ensure consistent performance across different printing conditions.
