Detergent composition for fibers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Textile products become entangled during washing due to frictional forces between fibers in wet conditions, making them difficult to remove from washing machines and leading to increased wrinkle formation and reduced softness.
Innovation Solution
A friction reducing agent for fibers comprising internal olefin sulfonate with 17-24 carbons and sulfosuccinic acid ester or its salt with 5-18 carbon hydrocarbon groups, applied at a 20-100% mass ratio, reduces friction between fibers, facilitating easier removal and enhancing softening and wrinkle resistance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional anionic surfactants are used for washing, then washing performance is achieved, but frictional force between fibers increases making textile products difficult to remove from washing machine
Solution Approach 1:
The invention changes the chemical parameters of the surfactant composition by using specific internal olefin sulfonates with 16 or more carbon atoms in combination with sulfosuccinic acid esters, achieving a unique molecular structure that reduces frictional force between fibers while maintaining washing performance
Solution Approach 2:
The invention creates a composite surfactant system combining internal olefin sulfonate and sulfosuccinic acid ester in specific ratios (20-80 wt% internal olefin sulfonate, 80-20 wt% sulfosuccinic acid ester), where the synergistic interaction between the two components achieves both washing performance and friction reduction
2Ease of operation
If frictional force between fibers increases during washing, then washing performance is maintained, but textile products become wrinkled and lose softness
Solution Approach 1:
The invention modifies the chemical composition parameters by incorporating internal olefin sulfonates with specific carbon chain lengths (16-24 atoms) and sulfosuccinic acid esters, creating a surfactant system that reduces inter-fiber friction and prevents wrinkle formation while preserving fabric softness
Solution Approach 2:
The surfactant composition acts as an intermediary substance between fibers during washing, forming a protective layer that reduces direct fiber-to-fiber contact and friction, thereby preventing wrinkles and maintaining softness
