Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Denim jeans are uncomfortable in warm temperatures due to inadequate cooling and moisture-wicking properties, leading to discomfort for wearers.
Innovation Solution
A yarn blend comprising jade-containing thermoplastic fibers, such as jade-containing polyester fibers, combined with hydrophobic cotton fibers and conventional fibers, which provides enhanced air permeability, moisture-wicking, and cooling effects when used in fabric construction, particularly in denim fabrics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional cotton yarn is used in denim fabric, then the fabric provides comfort and softness, but it lacks adequate cooling and moisture-wicking properties in warm temperatures
Solution Approach 1:
The invention uses a composite yarn structure combining hydrophobic cotton fibers with thermoplastic fibers containing jade powder. The hydrophobic cotton provides comfort and softness, while the jade-containing thermoplastic fibers provide cooling effects through their thermal properties and enhanced air permeability, thus resolving the contradiction between comfort and cooling effect
Solution Approach 2:
The invention applies local quality by treating only specific portions of the fabric structure with cooling functionality. The jade-containing thermoplastic fibers are strategically incorporated into the yarn blend to provide localized cooling zones where they contact the skin, while other portions maintain the comfort-providing hydrophobic cotton structure
2Strength
If conventional cotton yarn is used in denim fabric, then the fabric provides durability and strength, but it has inadequate moisture-wicking capabilities
Solution Approach 1:
The composite yarn combines hydrophobic cotton fibers that maintain strength and durability with jade-containing thermoplastic fibers that provide moisture-wicking properties. The hydrophobic nature of the cotton repels moisture while the thermoplastic component facilitates moisture transport, achieving both strength and moisture management
Solution Approach 2:
The jade-containing thermoplastic fibers create a porous structure within the yarn that enhances moisture-wicking capabilities through capillary action, while the overall yarn structure maintains the strength required for denim fabric through the hydrophobic cotton fiber framework
3Temperature
If jade powder is added to thermoplastic polymer, then the fiber provides cooling effect, but excessive jade powder interferes with fiber stability and usability
Solution Approach 1:
The invention optimizes the concentration parameter of jade powder in the thermoplastic polymer to achieve the desired cooling effect while maintaining fiber stability. By carefully controlling the amount of jade powder incorporated into the thermoplastic matrix, the fiber retains its structural integrity and usability while providing the intended cooling functionality

AI summary
The present disclosure describes a yarn comprising a blend of jade-containing fibers, such as jade-containing polyester fibers, with hydrophobic cotton fibers and optionally conventional fibers. The jade in the jade-containing polyester fibers provides the yarn with a cooling effect when it contacts a person's skin. The hydrophobic cotton fibers provide the yarn with hydrophobicity. When included in a fabric that also contains yarn having hydrophilic properties in a manner such that a higher percentage of the hydrophobic yarn is present on the back surface of the fabric than on the front surface of the fabric, the fabric has a cooling and moisture-wicking effect. The yarn may be used as the fill of a denim twill weave to provide denim clothing having enhanced cooling and moisture-wicking properties.
