Fiber Softener Composition for Long-Lasting Perfume Retention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fiber product treating agents face challenges in maintaining fragrance longevity while preserving the softness and fluffy feel of treated fibers, and existing methods for microencapsulation are complex and costly.
Innovation Solution
A fiber product treating agent comprising specific compounds represented by formulae (1-1) and (1-2) in combination with perfumes having a boiling point of 250°C or more and a logPow of 3 or more, which improves perfume retention without impairing the original properties of the agent.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of stationary object
If a perfume is simply blended with conventional fiber product treating agents, then the fragrance is initially present, but the longevity of perfume deteriorates rapidly during washing and drying
Solution Approach 1:
The patent introduces a specific fatty acid amide compound as an intermediary substance between the perfume and the fiber product treating agent. This mediator compound has the dual function of maintaining the softening performance of the treating agent while providing excellent fragrance retention through its molecular structure that resists degradation during washing and drying processes.
Solution Approach 2:
The patent changes the chemical parameters of the fiber product treating agent by incorporating a specific fatty acid amide compound with defined molecular weight and structure (formula (1) or (2)). This parameter change transforms the treating agent from one that loses fragrance quickly to one that maintains fragrance longevity while preserving softening ability.
2Duration of action of stationary object
If microencapsulation methods are used to improve perfume retention, then fragrance longevity is enhanced, but the production steps become complicated and costs increase
Solution Approach 1:
The patent extracts the complex microencapsulation process and replaces it with a simpler chemical composition approach. Instead of physically encapsulating perfume molecules in complex structures, the invention uses a specifically designed fatty acid amide compound that inherently provides fragrance retention through its chemical properties, eliminating the need for complex encapsulation equipment and processes.
Solution Approach 2:
The patent replaces expensive and complex microencapsulation materials with a cost-effective fatty acid amide compound that can be easily incorporated into conventional fiber product treating agents. This simpler substance achieves similar fragrance retention effects without the high production costs and complex manufacturing steps associated with microencapsulation.
3Ease of operation
If conventional fiber product treating agents are used, then softness and fluffy feel are provided, but perfume longevity is poor
Solution Approach 1:
The patent merges two previously separate functions into a single integrated composition: the softening function of conventional fiber product treating agents and the fragrance retention function of specially designed compounds. The fatty acid amide compound serves as a bridge that combines these functions, allowing the treating agent to provide both softness and long-lasting perfume without compromising either performance.
