1. Core Working Principles
- 
Solvent Release Mechanism: - 
Nano-encapsulation: Each microcapsule contains 0.5-2μL solvent, released gradually through fiber friction 
- 
Diffusion formula: Q=K·ΔP·t (Q=release amount, K=material coefficient, ΔP=pressure difference, t=time) 
 
- 
- 
Structural Design: - 
Sandwich architecture: PE barrier layer (anti-evaporation) + dual-gradient fibers (absorption/release balance) 
 
- 
2. Materials Science Perspective
✅ Fiber Properties:
- 
Polyester/nylon blend (0.3-0.8μm diameter) 
- 
Specific surface area >200m²/g (enhanced solvent loading) 
 ✅ Solvent Formulations:
- 
Electronic grade: 99% IPA + 0.1% corrosion inhibitor 
- 
Medical grade: 75% ethanol + 0.5% glycerol (humectant)
