Solution Overview
Problem
Existing transfer printing methods using ink jet technology on absorptive media like fabrics face issues of dye migration and poor ejection stability due to the absence of specific formulations for such media.
Innovation Solution
A treatment liquid comprising resin particles, a water-soluble organic solvent with specific compounds A and B, and a silicone-based surfactant, within defined content ranges, is used to form layers on a transfer medium before heat transfer to absorptive media, enhancing ejection stability and preventing dye migration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional treatment liquid is used on absorptive media, then the liquid can be applied to the medium, but dye migration occurs and ejection stability deteriorates
Solution Approach 1:
The patent changes the chemical parameters of the treatment liquid by specifying precise compositional ratios: resin particles (5-20 mass%), water-soluble organic solvent (80-95 mass%), and silicone-based surfactant (0.1-5 mass%). This parameter optimization resolves the contradiction by achieving both ejection stability and preventing dye migration through the synergistic effect of these specific concentrations
Solution Approach 2:
The treatment liquid is formulated as a composite material combining three distinct components: resin particles for adhesion and stability, water-soluble organic solvent for ejection performance, and silicone-based surfactant for surface tension control. This composite structure enables the liquid to simultaneously achieve stable ejection and prevent dye migration on absorptive media
2Strength
If the resin particles content is increased to improve adhesion, then transferability improves, but ejection stability deteriorates
Solution Approach 1:
The patent optimizes the resin particles content to a specific range of 5-20 mass%, balancing adhesion strength and ejection stability. Below 5% provides insufficient adhesion, while above 20% causes ejection instability. This precise parameter control resolves the contradiction between these two requirements
3Reliability
If the water-soluble organic solvent content is increased to improve ejection stability, then ejection stability improves, but the effectiveness in preventing dye migration deteriorates
Solution Approach 1:
The patent specifies the water-soluble organic solvent content at 80-95 mass%, ensuring high ejection stability while maintaining sufficient concentration of other components (resin particles and surfactant) to prevent dye migration. This balanced parameter setting resolves the contradiction
4Strength
If the silicone-based surfactant content is increased to improve surface tension control, then transferability improves, but the ejection stability deteriorates
Solution Approach 1:
The patent optimizes the silicone-based surfactant content to 0.1-5 mass%, where the surfactant provides sufficient surface tension control for improved transferability without excessive amounts that would compromise ejection stability. This precise parameter control resolves the contradiction
