Polyethylene Knitted Fabric for Moisture and Heat Release
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing masks cause skin irritation, retain moisture leading to heat retention, and lose antibacterial and deodorization properties after washing, necessitating a fabric that rapidly discharges moisture and heat without additives.
Innovation Solution
A knitted fabric using polyethylene yarn with specific melt index, polydispersity index, and crystallinity ranges, ensuring high water contact angle, peeling resistance, and antibacterial activity, maintaining functionality after washing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If cotton fabric is used for masks, then moisture absorption is improved, but moisture release function deteriorates and heat retention increases
Solution Approach 1:
The patent changes the fundamental material parameter from natural cotton fibers to synthetic polyethylene fibers, which have inherently different moisture management properties. This parameter change enables the fabric to repel moisture and release heat effectively, resolving the contradiction between moisture absorption and heat retention.
2Reliability
If functional additives are applied to fabric for antibacterial properties, then antibacterial function is improved, but fabric weight increases and washing durability deteriorates
Solution Approach 1:
The patent makes the polyethylene fabric itself possess antibacterial properties through its inherent hydrophobic surface characteristics, eliminating the need for external functional additives. This self-service approach maintains fabric lightness and washing durability while providing reliable antibacterial function.
3Temperature
If non-woven fabric made of synthetic fiber is used, then moisture release is improved, but skin irritation increases due to surface roughness
Solution Approach 1:
The patent employs a knitted fabric structure with inherent porosity and air permeability that allows moisture release while providing a smoother surface texture compared to non-woven fabrics. This structural approach simultaneously improves moisture release function and reduces skin irritation.
