Characteristics and uses of microfiber cleanroom wiper
Microfiber dust-free cloth is a special fabric made of polyester (polyester) and nylon (nylon) composite materials. With its unique physical structure and material combination, it plays a key role in high-cleanliness environments. Its core characteristics and main uses are as follows:
1. Core characteristics
Fine fiber structure:
Microfiber: The fiber diameter is only 1/20 of that of ordinary polyester, and the specific surface area is huge, which significantly improves the coverage, fluffiness and contact adsorption efficiency of pollutants.
Advantages of composite materials: The typical ratio is 80% polyester + 20% nylon (or 70% polyester + 30% nylon). Polyester provides structural stability and heat setting effect (skeleton effect), while nylon provides excellent softness, adsorption and wear resistance (skin effect), achieving both rigidity and softness.
Multiple cleaning mechanisms:
Multi-shaving effect: A single coarse fiber is superfine to form hundreds of fine fibers, which greatly increases the contact points for scraping pollutants.
Wide-contact effect: The fiber has low bending stiffness and is extremely soft, with a large contact area with the wiped surface and strong cleaning power.
Inner-trap effect: Dirt migrates outward through the fiber capillary channel and is locked inside to avoid secondary contamination and surface scratches.
Strong adsorption and wicking effect: It has super strong adsorption capacity for dust particles (especially <0.5μm), grease, fingerprints and liquids, and deep cleaning through wicking.
Excellent physical properties:
Soft and damage-free: The ultra-fine fiber brings ultra-low bending stiffness, feels extremely soft, and is not easy to scratch delicate surfaces (such as lenses, screens, and molds) when wiping.
Highly efficient liquid absorption and vapor permeability and waterproofing: The capillary structure formed by micropores makes it highly absorbent and waterproof and vapor permeable, which can quickly absorb liquids and reduce residues.
Low pollution: less dust, low ion release, low non-volatile residue (NVR) concentration, meeting high cleanliness requirements.
Durability: Nylon components improve wear resistance and tear resistance, and have a long service life.
Production process guarantee:
Precision edge sealing: Laser edge sealing or ultrasonic edge sealing (better than heat edge sealing) is used, the edges are flat and smooth, and fiber shedding and particle generation are minimized.
Clean production: Manufactured in high-grade clean rooms such as Class 100 to ensure initial cleanliness.
2. Main uses (suitable for medium and high cleanliness environments, typically Class 100~1000)
Semiconductor and electronic manufacturing: Wiping and cleaning of chips, microprocessors, hard drives, semiconductor assembly lines, PCB circuit boards, and SMT production line equipment.
Non-destructive cleaning of liquid crystal displays (LCDs), camera modules, optical lenses, LED screens, and precision instrument surfaces.
Precision manufacturing and optics:
Precision injection mold maintenance, ultra-high precision hardware, valve steel pipe accessories, and mold cleaning.
Removal of grease and fingerprints from easily scratched surfaces such as optical lenses and plastic electroplated parts.
Medical and pharmaceutical:
Cleaning of medical equipment and pharmaceutical production environments (in accordance with USP <797> and <800> wiping requirements).
Wiping of sterile rooms and laboratory equipment.
Automotive industry:
Dust removal of body surfaces before painting and cleaning of high-end automotive parts.
General high-cleanliness environment:
Wipe and clean equipment, work surfaces, parts and spills in dust-free workshops (ISO Class 3 - Class 7 / Class 1 - Class 100,000 / EU Class A - Class D).
