Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current polyester soil release polymers used in fabric and home care products are primarily fossil-based, which raises concerns about sustainability and environmental impact.
Innovation Solution
Development of fabric and home care compositions using polyesters that incorporate renewable sourced raw materials, specifically comprising structural units (A), (B), (C), and optionally (D), which provide effective soil release and whiteness maintenance benefits.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If fossil-based terephthalate polyester is used, then soil release performance is achieved, but sustainability and environmental friendliness deteriorate
Solution Approach 1:
The patent changes the chemical composition parameters of the polyester by incorporating renewable-derived structural units (A) and (B) alongside conventional terephthalate units. This compositional parameter change maintains the soil release performance while improving sustainability, directly resolving the contradiction between reliability and environmental harm.
Solution Approach 2:
The patent creates a composite polyester structure combining multiple structural units: renewable-based units (A) and (B), conventional terephthalate units, and glycol units (C). This composite approach allows the material to inherit beneficial properties from each component, achieving both sustainability and effective soil release performance.
2Object-affected harmful factors
If renewable-based polyesters are developed, then sustainability is improved, but performance consistency may deteriorate
Solution Approach 1:
The patent designs structural unit (A) with multiple functional capabilities: it provides renewable content for sustainability, contributes to soil release through its chemical structure, and maintains compatibility with conventional polyester processing. This multi-functionality ensures performance consistency while achieving sustainability goals.
Solution Approach 2:
The patent introduces specific structural units (A) and (B) with defined chemical properties at specific positions within the polyester chain. By controlling the local chemical structure and composition ratios, the patent ensures consistent performance characteristics while incorporating renewable materials throughout the polymer structure.
