Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current functionalized silicones used in fabric care products lack environmental sustainability and do not effectively degrade, posing challenges in terms of energy consumption and disposal, while also failing to maintain or enhance performance benefits like fabric softness and stain control.
Innovation Solution
Development of functionalized siloxane polymers with a cleavable bond that promotes biodegradability, incorporating a surfactant and ester quaternary ammonium compounds, which are stable within specific pH ranges, to create a composition that maintains performance benefits while being environmentally friendly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional functionalized silicones are used to provide fabric care benefits, then performance benefits such as fabric softness and stain control are achieved, but environmental sustainability deteriorates and biodegradability is poor
Solution Approach 1:
The patent modifies the chemical structure of traditional silicones by introducing cleavable bonds (such as ester, carbamate, or urea groups) into the siloxane backbone. This structural parameter change enables the polymer to degrade under environmental conditions while maintaining the desired fabric care properties during use.
Solution Approach 2:
The invention creates a composite structure combining siloxane units with cleavable functional groups (ester, carbamate, or urea). This composite approach integrates the performance benefits of traditional silicones with the biodegradability of environmentally friendly materials, achieving both reliability and reduced environmental harm.
2Reliability
If traditional silicones are used to maintain fabric softness and wrinkle control, then these performance benefits are achieved, but energy consumption and disposal requirements worsen
Solution Approach 1:
The cleavable bonds in the siloxane polymer structure allow the material to be discarded or degraded after serving its function. The environmental breakdown products are less harmful and require less energy for disposal compared to traditional silicones, while the polymer maintains full fabric care performance during its service life.
3Object-affected harmful factors
If functionalized silicones with cleavable bonds are introduced to improve biodegradability, then environmental sustainability is improved, but the complexity of the polymer structure increases
Solution Approach 1:
The siloxane backbone is segmented by incorporating discrete cleavable functional groups (ester, carbamate, or urea units) at specific positions. This segmentation allows the polymer to maintain its overall structural integrity for performance benefits while providing specific breakdown points for environmental degradation, managing complexity through targeted modification rather than complete structural redesign.
