Temperature-Responsive Fiber for Dynamic Moisture Regulation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional clothing with moisture absorption and sweat dissipation loses temperature/humidity regulation function due to sultriness during exercise, especially under saturated humidity conditions, failing to maintain thermal comfort.
Innovation Solution
A temperature-responsive material with a specific structure, compatible with polyester, is melt-spun to form a fiber that dynamically adjusts temperature and humidity by changing hydrophilicity/hydrophobicity with temperature, using a combination of polybutylene terephthalate, polyethylene terephthalate, and antioxidants, enabling fast drying and reduced heat loss.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If conventional fabric structure design and finishing technique are used for moisture absorption and sweat dissipation, then moisture absorption function is improved, but temperature regulation function is lost due to sultriness during exercise
Solution Approach 1:
The patent applies parameter changes by incorporating temperature-responsive materials that alter their hydrophilicity based on temperature changes. The material transitions from hydrophilic at lower temperatures to hydrophobic at higher temperatures, dynamically adjusting moisture absorption properties to maintain thermal comfort during exercise without losing temperature regulation function
Solution Approach 2:
The patent uses composite materials by combining temperature-responsive materials with polyester base materials through melt spinning. This creates a composite fiber structure that integrates the moisture absorption capability of the temperature-responsive material with the durability and comfort properties of polyester, achieving both moisture absorption and temperature regulation functions simultaneously
2Quantity of substance
If single/double sided coating finishing technique is applied, then moisture absorption is enhanced, but temperature/humidity regulation function is lost under saturated humidity conditions
Solution Approach 1:
The patent applies dynamics by using temperature-responsive materials that dynamically change their properties based on temperature. The material's hydrophilicity-hydrophobicity transitions with temperature changes, enabling adaptive regulation of moisture absorption and temperature/humidity balance under varying environmental conditions including saturated humidity during exercise
3Ease of manufacture
If conventional fabric is used, then manufacturing simplicity is maintained, but fast-drying and coolness properties are insufficient during exercise
Solution Approach 1:
The patent applies self-service by incorporating temperature-responsive materials that automatically adjust their moisture absorption properties in response to temperature changes without requiring external control mechanisms. The material self-regulates its hydrophilicity based on body temperature and environmental conditions, providing fast-drying and coolness properties while maintaining manufacturing simplicity through melt spinning integration

Function Achieved in This Case
The temperature-responsive fiber maintains thermal comfort by accelerating moisture evaporation at high temperatures for cooling and slowing moisture loss at low temperatures, effectively overcoming the limitations of conventional clothing.
Implementation Method 1
A temperature-responsive material with a specific structure, compatible with polyester, is melt-spun to form a fiber that dynamically adjusts temperature and humidity by changing hydrophilicity/hydrophobicity with temperature
Implementation Method 2
The temperature-responsive fiber maintains thermal comfort by accelerating moisture evaporation at high temperatures for cooling
Implementation Method 3
The prepared temperature-responsive material is highly compatible with a polyester base material and therefore can be melt spun to prepare an intrinsic temperature-responsive fiber
