Alphalite® Polyester Cleanroom Wipers Lightweight Polyester Wipes for ISO 5–8 Controlled Cleaning Alphalite polyester cleanroom wipes provide lightweight, low-lint wiping performance designed for contamination-controlled environments including semiconductor fabs, pharmaceutical manufacturing, biotechnology laboratories, optics production, and electronics assembly. ▼ EXPAND TECHNICAL REFERENCE
Lightweight Polyester Wipers for Controlled Cleaning
Alphalite polyester cleanroom wipes are engineered to provide controlled lint performance and dependable wiping capability while maintaining a lighter fabric weight than heavier knit polyester wipe formats. This lightweight construction helps improve wipe conformability and operator handling while still delivering the contamination control required in many clean manufacturing environments.
Manufactured from continuous filament polyester fibers, Alphalite wipes minimize fiber shedding compared with staple-fiber wiping materials. Their lighter construction makes them well suited for general surface cleaning, equipment wipe-down procedures, and workstation maintenance in ISO Class 5–8 environments.
These wipes are commonly used in semiconductor support areas, pharmaceutical production environments, biotechnology labs, optics manufacturing facilities, and precision electronics assembly operations where controlled wiping performance is required without the heavier structure of high-density polyester wipes.
Continuous Filament Polyester Construction
Continuous Filament Fibers:
Long polyester filaments significantly reduce lint generation compared with natural fiber wipes and staple fiber fabrics.
Lightweight Knit Structure:
The lighter fabric weight improves wipe flexibility and surface conformity while maintaining strong wiping performance.
Edge Sealing Options:
Many Alphalite wipes feature laser or ultrasonic sealed edges to further reduce fiber release during wiping.
