Textile Detergent Composition for Low Fiber Adsorption
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional detergent compositions for textile products often result in surfactants adsorbing to fibers during washing, leading to reduced detergency and increased rinsing difficulties, particularly when using internal olefin sulfonates as raw materials.
Innovation Solution
A detergent composition comprising an internal olefin sulfonate with 15-24 carbon atoms and a sulfonate group positioned at least at carbon 5, combined with a nonionic surfactant having a high HLB value, which reduces surfactant adsorbability to fibers and maintains consistent detergency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If internal olefin sulfonate is used as a surfactant component, then detergent composition provides good cleaning performance, but surfactant adsorbs excessively to textile fibers during washing
Solution Approach 1:
The patent applies parameter changes by specifying precise structural parameters of the internal olefin sulfonate: carbon atom count (15-24) and sulfonate group position (at least at carbon 5). These parameter specifications optimize the balance between detergent performance and fiber adsorption, resolving the contradiction by tuning molecular structure to achieve desired performance characteristics.
Solution Approach 2:
The patent uses composite materials by combining internal olefin sulfonate with nonionic surfactants in specific formulations. This composite approach leverages the synergistic effects between different surfactant types to maintain effective cleaning while reducing excessive fiber adsorption, as the nonionic component modulates the overall surfactant-fiber interaction.
2Ease of manufacture
If conventional surfactant formulations are used, then detergent composition is simple to manufacture, but surfactant adsorption increases rinsing difficulties
Solution Approach 1:
The patent applies parameter changes by optimizing the hydrophilic-lipophilic balance (HLB) of the surfactant system and specifying molecular structure parameters. These changes improve rinsing performance by reducing fiber adsorption while maintaining formulation simplicity through straightforward mixing of defined components.
Solution Approach 2:
The patent introduces nonionic surfactants as intermediary substances that mediate between the internal olefin sulfonate and textile fibers. This intermediary approach reduces direct adsorption interactions, improving rinsing ease while keeping the overall formulation process simple.
3Adaptability or versatility
If internal olefin sulfonate composition is altered to optimize performance, then detergency varies, but formulation flexibility increases
Solution Approach 1:
The patent applies parameter changes by establishing specific ranges for carbon atoms (15-24) and sulfonate group positions (at least at carbon 5) that maintain consistent detergency. Within these constrained parameter ranges, formulation flexibility is preserved, allowing optimization while ensuring reliable performance.
Solution Approach 2:
The patent implements feedback by establishing clear structural criteria and performance benchmarks for the internal olefin sulfonate. This feedback mechanism ensures that any compositional alterations maintain detergency consistency by reference to the defined parameters, while still allowing formulation flexibility within acceptable ranges.
