Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional home textile softeners, both liquid and sheet types, face inefficiencies in low-temperature water, with liquid types being cumbersome and sheet types only effective at high dryer temperatures due to poor solubility and dispersibility of active ingredients.
Innovation Solution
A composition for textile softener comprising cationic surfactants with specific alkyl group ratios, applied to a substrate sheet, ensuring excellent solubility and dispersibility in low-temperature water, mimicking liquid softeners' effectiveness during washing machine rinse cycles while retaining the convenience of sheet softeners.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If sheet typed textile softener is used, then ease of use and lightness are improved, but solubility and dispersibility in low temperature water deteriorate
Solution Approach 1:
The patent modifies the chemical parameters of the cationic surfactant by controlling the ratio of saturated to total hydrocarbon groups (Q/T ≥ 0.6) and specifying chain length ranges (C7-C21), which fundamentally changes the surfactant's solubility characteristics in low temperature water while maintaining its effectiveness on sheets
Solution Approach 2:
The patent creates a composite formulation by combining the specifically structured cationic surfactant with auxiliary agents including emulsifiers, solvents, and optional components in defined proportions, resulting in a composition that achieves both sheet compatibility and low temperature water solubility
2Reliability
If liquid phase textile softener is used, then solubility in water is improved, but weight and handling convenience deteriorate
Solution Approach 1:
The patent utilizes phase transition by formulating a composition that transitions from a liquid-like soluble state in water to a solid-supported state on sheets, allowing the softener to exhibit liquid-phase solubility benefits during washing while maintaining solid-phase handling convenience through sheet support
Solution Approach 2:
The patent introduces a substrate sheet as an intermediary carrier that mediates between the liquid softener composition and the washing process, allowing the composition to be applied conveniently on sheets while maintaining its solubility and dispersibility properties in low temperature water during the rinse cycle
3Ease of operation
If conventional sheet typed textile softener is used, then ease of use is improved, but effectiveness in washing machine rinse cycle deteriorates
Solution Approach 1:
The patent changes the critical parameters of the cationic surfactant structure, specifically ensuring Q/T ≥ 0.6 and using saturated hydrocarbon groups with C7-C21 chains, which enables the surfactant to remain effective in low temperature water during washing machine rinse cycles while still being suitable for sheet application
Solution Approach 2:
The patent applies local quality by optimizing specific regions of the surfactant molecule (the hydrocarbon chain saturation and length) to provide different local properties: sufficient hydrophobicity for sheet attachment and sufficient hydrophilicity for low temperature water solubility and effectiveness

AI summary
Disclosed is a composition for textile softener containing a cationic surfactant, the ratio of which C7-C21 alkyl substituents analyzed by HLPC (high pressure liquid chromatography) or GC (gas chromatography) is 0.6 or more, as an effective ingredient, a sheet for textile softener including the same, and method of softening a textile using the sheet. Since the composition for textile softener has excellent dissolving and dispersing effect even in low temperature water, the sheet containing this composition is used at a rinse time during washing procedures to represent excellent anti-static effect and textile softening effect to textiles and clothes.
