Lijiejing dust-free cloths are specifically designed to meet the core requirements for glass cleaning in the optoelectronic display industry. They offer precise selection across five key dimensions—material, edge finishing, basis weight, anti-static properties, and solvent resistance—ensuring both optimal cleaning performance and product protection. Specific details are as follows: Material Selection: For precision cleaning and abrasion resistance, we highly recommend Lijie Clean microfiber dust-free cloths. The preferred blend is 70% polyester + 30% nylon, with fiber diameter ≤0.1 denier. This allows deep penetration into microscopic surface crevices to trap dust and contaminants, while offering liquid absorption capacity exceeding three times its own weight. Its soft texture eliminates scratching risks, making it ideal for high-precision cleaning applications like LCD panels and optical lenses. For frequent wiping or high abrasion resistance, opt for pure polyester lint-free cloth. Its stable structure and high strength withstand repeated friction, making it suitable for general cleaning needs like electronic component housings and glass substrates. Select by Sealing Method: Matching Cleanroom Grade For Class 10/Class 100 high-cleanliness dust-free workshops (e.g., OLED vapor deposition, polarizer lamination), prioritize ultrasonically sealed dust-free cloths. High-frequency vibration thermally fuses the edges, creating soft, seamless borders with minimal shedding to prevent secondary contamination. For Class 1000+ clean environments or general cleaning scenarios, laser-sealed wipes offer better cost-effectiveness. Their high-temperature fused edges minimize particle residue, meeting routine cleaning requirements. Select by Grammage: Matching Wiping Area and Scenario Precision For large-area wiping (e.g., cleaning entire optical glass substrates), choose 180gsm high-grammage wipes. Their high liquid absorption capacity and wiping efficiency reduce the frequency of cleaning solution reapplication. For localized cleaning or post-polishing finishing, we recommend low-grammage soft-type Lijie clean wipes (fiber diameter ≤0.3μm) with plain or grid weaves. Plain weave suits general dust removal, while grid weave absorbs liquids faster and prevents scratching precision coatings on glass surfaces. Select based on anti-static properties: Mitigate electrostatic adhesion risks. Photovoltaic display glass is prone to electrostatic dust attraction. Choose Lixin low-static lint-free cloth with surface resistance controlled between 10^6-10^8Ω and friction voltage ≤100V, capable of rapid static dissipation within 1.5 seconds. This effectively prevents friction-generated static during wiping, avoids attracting charged particles from the air, and ensures stability for subsequent processes like coating and lamination. Solvent Resistance Selection: Adapting to Cleaning Agent Scenarios When wiping requires electronic-grade isopropyl alcohol (EL grade, purity ≥99.99%) or ethanol, select Lijie Clean dust-free cloth tested to ISO 15790 standards. Its PET fibers exhibit <1% shrinkage in ethanol, resisting solvent erosion without swelling or deformation. This ensures no fiber shedding during wiping while maintaining consistent cleaning performance.
