Neutral Detergent for Protein Fabrics Using High-Viscosity Polymer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional detergents for partial cleaning are not suitable for protein-based fabrics like wool and silk, as they can cause shrinkage or deformation due to alkalinity, and require washing with water, making them inapplicable to dry-cleaned items and inefficient in surfactant usage.
Innovation Solution
A detergent composition containing a polymer with a specific structure that provides high viscosity for effective stain removal without alkali, combined with reduced surfactant content and the inclusion of alkylene glycol for stability, allowing for direct application and wiping off stains without water washing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If alkaline detergent is used for partial cleaning, then cleaning effectiveness on cotton and shirts is improved, but inapplicability to wool and silk clothes occurs due to shrinkage and deformation
Solution Approach 1:
The patent changes the pH parameter from alkaline to neutral or weakly acidic by using organic acid and its reactive derivative instead of traditional alkaline agents. This parameter change enables the detergent to be safe for protein-based fabrics like wool and silk while maintaining cleaning effectiveness on cotton and synthetic fabrics through the synergistic action of surfactants and acid-based stain removal mechanisms.
2Productivity
If conventional surfactant amount (15-30%) is used in detergent for partial cleaning, then cleaning power is improved, but the step of washing with water using a washing machine is required which causes inapplicability to dry cleaning clothes
Solution Approach 1:
The patent uses a reduced amount of surfactant (0.1-5% by weight) compared to conventional detergents (15-30%), combined with organic acid and its reactive derivative that provide enhanced stain removal capability. This partial action approach allows effective stain removal without requiring extensive water rinsing, enabling direct application and wiping off for dry-cleaned items while maintaining adequate cleaning power through the synergistic formulation.
3Productivity
If potassium hydroxide is used in portable stain remover, then cleaning effectiveness is improved, but inapplicability to protein-based clothes and shrinkage occurs when sodium bicarbonate is used
Solution Approach 1:
The patent replaces strong inorganic bases like potassium hydroxide and sodium bicarbonate with organic acid and its reactive derivative, fundamentally changing the chemical nature of the active ingredient. This parameter change eliminates the harmful effects of alkalinity on protein-based fabrics while maintaining effective stain removal capability through the organic acid's ability to break down stains and the synergistic action with surfactants.
