As the core consumable in the field of precision cleaning, the microfiber dust-free cloth is made of 80% modified polyester fiber and 20% nylon fiber composite braid. Its unique three-dimensional honeycomb fiber structure is processed by laser edge sealing and is cut and packaged in an ISO level 5 (level 100) clean room environment to ensure that the initial cleanliness of the product reaches the micron standard. This innovative material combination gives the fabric a 0.08dtex level microfiber characteristic, and its monofilament diameter is only 1/100 of that of human hair, effectively avoiding microscratch problems caused by traditional cleaning tools.
The core advantages of this product are reflected in the four-dimensional clean performance system: first, its micro-trench fiber structure has an interception efficiency of 98.7% for particulate matter above 0.3μm (ASTM F51 standard test), which is especially suitable for the removal of nonlevel pollutants on the surface of semiconductor wafers; second, the material has been specially modified to treat, and oily pollutants can be adsorbed 3 times its own weight per square centimeter, showing excellent performance in the precision optical lens wiping scenario; further, through ion leaching control technology, chloride ion residue is controlled below 0.1μg/cm², which fully meets the strict requirements of the sterile preparation production environment in the USP
In the industrial application dimension, this product shows three scenario adaptability: First, in a high-temperature process environment (≤205℃), it can be used as a pre-cleaning medium for vacuum coating equipment to effectively remove organic residues on the surface of the substrate; second, when used with polar solvents such as isopropanol, its removal efficiency of photoresist residues is 42% higher than that of ordinary dust-free cloth; third, in the field of biopharmaceuticals, its unique low NVR (nonvolatile residue<10μg/cm²) characteristics ensure that no secondary pollution is introduced during the cleaning of the lyophilized machine cavity. It is worth noting that its high gram weight design of 160g/m² increases the liquid storage per unit area to 1.8 times that of conventional products, which is especially suitable for continuous wipe operations of large-sized LCD panels.
From the perspective of the quality control system, the product strictly follows the IEST-RP-CC004.3 standard for production. Each ultrasonic edge sealing process has been inspected by 3D microscope to ensure that the edge sealing width tolerance is controlled within ±0.1mm. This precision manufacturing process enables the product to obtain wide application certification in key areas such as aerospace fuel sensor cleaning and medical implant surface treatment. After verification by third-party laboratories, using this dust-free cloth for terminal cleaning of medical devices can increase the bioload pass rate to 99.3%, significantly better than the requirements of ISO 13485 standard.
