Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing textile treatment methods face challenges in controlling foam formation during washing and other treatments without hindering washing performance, particularly in drum-type washing machines and systems with specific drainage structures.
Innovation Solution
A treatment liquid comprising sulfosuccinic acid esters and specific surfactants is used to maintain foam in a moderate manner by forming vesicles and utilizing hydrated solids to break foam without interfering with treatments, satisfying certain component ratios and including a hardness component.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If detergent compositions with high foaming performance are used to improve washing performance, then washing performance is improved, but excessive foam formation occurs causing overflow during washing
Solution Approach 1:
The invention converts the harmful excessive foam into beneficial moderate foam by using sulfosuccinic acid esters that form vesicles instead of excessive foam. The vesicle structure provides the necessary foaming for washing performance while the controlled foam characteristics prevent overflow, thus converting the harmful effect into a beneficial one.
Solution Approach 2:
The invention changes the chemical composition parameters by using sulfosuccinic acid esters with specific hydrocarbon groups (5-18 carbons) and controlling the proportion of component (a) to component (b1) or (b2) within specific ranges. This parameter change transforms the foam-forming characteristics from excessive to moderate, maintaining washing performance while preventing foam overflow.
2Loss of substance
If water-saving washing methods are used to reduce water consumption, then water efficiency is improved, but foam control is needed to prevent excessive foam formation
Solution Approach 1:
The invention converts the harmful excessive foam that typically results from water-saving concentrated washing into beneficial moderate foam. By using sulfosuccinic acid esters that form vesicles, the system achieves effective washing with reduced water while maintaining controlled foam levels that do not cause overflow.
3Object-generated harmful factors
If foam control measures are implemented to prevent foam overflow, then foam control is improved, but washing performance may be hindered
Solution Approach 1:
The invention eliminates the need for separate foam control measures by converting the foam-forming mechanism itself. The sulfosuccinic acid esters form vesicles that produce moderate foam inherently, so foam control is achieved not by suppressing foam but by transforming the foam-forming process to naturally produce controlled, beneficial foam that maintains washing performance.
Solution Approach 2:
The invention changes the fundamental chemical parameters by using sulfosuccinic acid esters with specific structures and controlling their proportion within specific ranges. This parameter change fundamentally alters the foam characteristics from excessive to moderate, allowing washing performance to be maintained without additional foam control measures.
4Reliability
If conventional surfactant systems are used to achieve washing performance, then washing performance is maintained, but foam control becomes problematic in specific washing equipment and drainage systems
Solution Approach 1:
The invention changes the surfactant system parameters by using sulfosuccinic acid esters with specific hydrocarbon group sizes (5-18 carbons) and controlling the proportion of component (a) to component (b1) or (b2) within specific ranges. This parameter change makes the system adaptable to various washing equipment and drainage systems by producing moderate foam that does not cause overflow, while maintaining washing performance.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The method effectively suppresses and eliminates foam during textile treatments, ensuring effective washing and other processes without excessive foam overflow, maintaining treatment quality.
Implementation Method 1
component (a) is considered to create an association state called a vesicle in a specific concentration region
Implementation Method 2
the hydrated solids formed by component (a) and hardness components in water (for example, calcium ions) act on foam formed by water and component (b) and break this foam
