Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current textile materials do not effectively combine high emissivity for far infrared radiation with properties like impermeability to liquid water, permeability to water vapor, and breathability, which are essential for comfort and thermal protection in clothing and textiles.
Innovation Solution
A composite textile material is developed, comprising ceramic particles dispersed in a polymer matrix, specifically polyurethane, with ceramic oxides like MnO2 and Co2O3, which emits far infrared radiation and provides improved comfort and thermal protection by promoting blood circulation and temperature regulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a ceramic coating layer is applied to a textile fabric to improve far infrared emission, then the emissivity is improved, but the manufacturing precision and quality control become difficult
Solution Approach 1:
The patent changes the ceramic content parameter within specific ranges (1-60% by mass) to optimize emissivity while maintaining manufacturability. It also specifies ceramic particle size parameters (0.1-10 μm) to ensure proper dispersion and coating quality, resolving the contradiction between high emissivity and manufacturing precision.
Solution Approach 2:
The patent creates a composite material system combining polymer matrix with ceramic particles, where the polymer provides structural integrity and the ceramic provides emissivity. This composite approach allows simultaneous achievement of high emissivity and controlled coating properties through material composition optimization.
2Reliability
If a thick ceramic coating is applied to maximize far infrared emission, then the emissivity is improved, but the textile material loses breathability and water vapor permeability
Solution Approach 1:
The patent optimizes the ceramic content parameter to specific ranges (1-60% by mass) rather than using maximum possible amounts. This parameter optimization ensures sufficient emissivity while maintaining adequate porosity and breathability of the textile material.
Solution Approach 2:
The patent specifies ceramic particle size parameters (0.1-10 μm) to create appropriate local structure in the coating. The controlled particle size ensures proper dispersion and maintains孔隙 structure that allows water vapor transmission while providing effective infrared emission.
3Reliability
If ceramic particles are dispersed in polymer matrix to create composite material, then the far infrared emission is improved, but the manufacturing process complexity increases
Solution Approach 1:
The patent employs a composite material approach combining polymer and ceramic, where the polymer matrix simplifies handling and processing while the ceramic particles provide the desired emissivity function. This composite structure allows conventional textile manufacturing processes to be used with minimal modification.
Solution Approach 2:
The patent specifies ceramic content parameters (1-60% by mass) that can be easily controlled during standard coating and drying processes, avoiding the need for complex specialized manufacturing equipment or processes.
