Heat-Treated Thermoplastic Yarn for Knit Rigidity Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing knit products lack optimal regulation of rigidity and elasticity, particularly in regions subjected to varying loads and wear, limiting their performance in garments and footwear.
Innovation Solution
Integration of thermoplastic yarns into knit textile layers, which can be heat-treated to alter properties such as impact attenuation, abrasion resistance, and friction reduction, by strategically arranging thermoplastic yarns within specific knit structures and configurations to control rigidity and elasticity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If thermoplastic yarns are integrated into knit textile layers and heat-treated, then wear resistance and rigidity are improved in targeted zones, but elasticity is reduced
Solution Approach 1:
The patent applies local quality by integrating thermoplastic yarns into specific zones of the knit textile layer where enhanced wear resistance and rigidity are needed, rather than uniformly throughout the entire garment. This allows different regions to have different properties - targeted zones gain improved durability and structure while other areas maintain their natural elasticity and comfort.
Solution Approach 2:
The patent uses composite materials by combining thermoplastic yarns with conventional knit yarns in the same textile layer. The thermoplastic yarns provide enhanced wear resistance and rigidity when heat-treated, while the conventional yarns maintain elasticity and comfort, creating a composite structure that balances contradictory properties within the same garment.
2Strength
If thermoplastic yarns are heat-treated to increase rigidity, then impact attenuation and abrasion resistance are improved, but the overall flexibility of the knit product is reduced
Solution Approach 1:
The patent applies local quality by strategically placing heat-treated thermoplastic yarns in specific zones where impact attenuation is most needed, such as high-wear areas or impact-prone regions, while leaving other areas untreated to maintain overall flexibility and comfort of the garment.
3Strength
If thermoplastic yarns are integrated to provide targeted compression zones, then fit and support are improved, but the comfort in high-compression areas is reduced
Solution Approach 1:
The patent applies local quality by creating targeted compression zones using heat-treated thermoplastic yarns in specific areas requiring support and fit, while maintaining lower compression and higher comfort in other areas of the garment, thus balancing medical/supportive needs with wearer comfort.
