Solution Overview
Problem
Existing pretreatment agents for ink-jet printing on fabrics often include function-adding components that users may not need, complicating convenience and flexibility in application.
Innovation Solution
A composition comprising a first composition with water, a polyvalent metal salt, a polymer, or a surfactant, mixed with a second composition containing an amino acid or a cross-linking agent with an oxazoline group, allowing users to opt for function addition based on purpose, improving convenience and performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If function-adding components are included in the pretreatment agent, then washing fastness and color development are improved, but user convenience deteriorates due to unnecessary complexity for users who do not desire additional functions
Solution Approach 1:
The pretreatment agent is divided into two separate compositions: a base composition containing essential pretreatment components (polyvalent metal salt, polymer, or surfactant) and a function-adding composition containing optional functional components (amino acid or cross-linking agent). Users can select and mix only the function-adding composition when additional functions like improved washing fastness or color development are needed, avoiding unnecessary complexity for basic use.
2Reliability
If multiple components are included in the pretreatment agent, then performance is improved, but device complexity increases
Solution Approach 1:
The composition is segmented into a base composition and a function-adding composition. The base composition contains minimal essential components for basic pretreatment functionality. The function-adding composition contains optional components (amino acid or cross-linking agent) that provide enhanced performance. This segmentation reduces overall system complexity while maintaining the capability for high performance when needed.
