Residue-Free Lint-Free Wiping Technology:

1. Core Value of Alcohol-Free Cleaning

• Technological Breakthrough:

  • Nano-fiber weaving technology (fiber diameter 0.1-0.3μm)

  • Plasma surface treatment reduces surface tension

• Industry Significance:

  • Eliminates “rainbow effect” caused by alcohol evaporation

  • Meets zero-contamination requirements for semiconductors/optical components

2. Three Key Technologies

✅ Material Innovation:

• Composite microfibers (polyester + nylon 6.6 blend)

• Embedded ionic liquids replace alcohol
  ✅ Process Breakthrough:

• Vacuum impregnation (liquid distribution uniformity ±2%)

• Laser micro-pores control release rate
  ✅ Verification System:

• GC-MS residue detection (LOD <0.01ppm)

• White light interferometry for surface roughness

3. Standardized Procedure

1. Pre-treatment:

   • Plasma cleaning removes static

2. Primary Cleaning:

   • Dry wiping for particle removal

3. Secondary Cleaning:

   • Pre-moistened wipes (0.2-0.5N/cm² pressure)

4. Verification:

   • Atomic Force Microscopy (AFM) inspection

4. Industry Applications

• 7nm Chip Manufacturing: Lithography lens maintenance

• Aerospace Optics: Satellite CCD sensor cleaning

• Medical Implants: Artificial joint surface treatment
