Coated textile
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing plant-based textiles struggle to match the quality and aesthetic appeal of animal leather, often containing only a small fraction of naturally derived compounds and combining with toxic, carcinogenic chemical polymers that pose environmental issues.
Innovation Solution
A coated textile made from a cellulosic substrate with a coating composition comprising at least 35% desugared grape pomace and at least one bio-based binder, totaling at least 65% bio-based materials, utilizing a manufacturing process that reduces sugar content and micronizes grape pomace to enhance adhesion and aesthetics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If plant-based materials are used to create leather alternatives, then environmental friendliness and consumer acceptance improve, but quality and aesthetic appearance deteriorate
Solution Approach 1:
The patent creates a composite coating composition combining multiple plant-based materials (grape pomace, tannins, starches, proteins, lipids, waxes) with natural resins and oils to achieve both aesthetic quality and environmental sustainability. This composite approach allows the material to mimic genuine leather's appearance and texture while remaining fully biodegradable and free from synthetic polymers.
Solution Approach 2:
The patent modifies the chemical and physical parameters of plant-based materials through controlled processing, including particle size reduction of grape pomace, optimization of tannin extraction, and adjustment of binder composition ratios. These parameter changes enable the coating to achieve desirable aesthetic properties such as grain structure, color, and tactile feel while maintaining high plant-based content.
2Object-affected harmful factors
If plant-based materials are used to create leather alternatives, then environmental friendliness improves, but adhesion and durability worsen
Solution Approach 1:
The patent optimizes adhesion by adjusting parameters including the particle size distribution of grape pomace (0.04-2.0 mm), the ratio of binding agents (starches, proteins, lipids, waxes), and the concentration of natural resins. These parameter modifications ensure strong substrate adhesion and coating durability while maintaining 100% plant-based composition.
Solution Approach 2:
The coating composition uses a composite system of multiple plant-based binding agents (starches, proteins, lipids, waxes) and natural resins working synergistically to achieve strong adhesion. This composite approach compensates for the individually limited bonding strength of single plant-based materials while keeping the formulation fully biodegradable and free from synthetic polymers.
3Manufacturing precision
If chemical polymers are combined with plant-based materials, then quality and aesthetic appearance improve, but toxicity and recyclability worsen
Solution Approach 1:
The patent extracts and eliminates all synthetic chemical polymers from the coating formulation, retaining only plant-based materials. This extraction of harmful components is achieved by using exclusively naturally derived binders (starches, proteins, lipids, waxes) and natural resins, thereby achieving high aesthetic quality without any toxic or carcinogenic substances.
Solution Approach 2:
The patent modifies the chemical composition parameters to exclude all synthetic polymers and their associated toxins. By adjusting the formulation to use only plant-based materials with controlled molecular weights and degradation rates, the patent achieves desirable aesthetic and mechanical properties while ensuring complete biodegradability and elimination of harmful factors.
