Solution Overview
Problem
Current textile printing methods using ink jet technology face challenges in achieving sufficient friction fastness and texture while minimizing bleeding, particularly due to the insufficient interaction between the treatment solution and ink jet ink compositions, which often results in poor color developability and texture quality.
Innovation Solution
A set comprising a treatment solution composition containing organopolysiloxane particles and water, and an ink jet ink composition with a pigment and water, where the static surface tension ratio between the treatment solution and ink jet ink compositions is optimized to ensure effective coverage and adhesion, with the treatment solution composition having a static surface tension between 25 to 40 mN/m and the ink jet ink composition set to 1, facilitating improved friction fastness and color developability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a treatment solution containing organopolysiloxane is used to improve friction fastness and texture, then friction fastness and texture are improved, but bleeding increases and color developability deteriorates
Solution Approach 1:
The patent applies parameter changes by optimizing the static surface tension of the treatment solution to be 25-40 mN/m and controlling the ratio between the static surface tension of the ink jet ink composition and treatment solution to be 0.65-0.85. This specific parameter range allows the treatment solution to provide sufficient friction fastness and texture improvement while preventing excessive bleeding and maintaining color developability.
Solution Approach 2:
The patent uses a composite material approach by formulating the treatment solution with organopolysiloxane particles combined with specific surfactants and co-surfactants. This composite formulation creates a balanced system where the organopolysiloxane provides friction fastness and texture, while the surfactant-co-surfactant combination controls surface tension to prevent bleeding and maintain color developability.
2Area of stationary object
If the static surface tension of the treatment solution is increased to improve coverage, then coverage is improved, but adhesion to ink layer deteriorates
Solution Approach 1:
The patent resolves this contradiction by precisely controlling the static surface tension parameter within the 25-40 mN/m range and maintaining the ratio with ink jet ink composition static surface tension between 0.65-0.85. This optimized parameter range ensures that the treatment solution achieves adequate coverage while maintaining strong adhesion to the ink layer, preventing both poor coverage and poor adhesion.
