NOVA-TECH 1000 Cleanroom Wipers are made from a hydroentangled non-woven material composed of 45% polyester and 55% cellulose. They are tough, abrasion resistant, absorbent, and virtually free of particle generation. The synergistic blend of virgin polyester and cellulose is hydro-entangled into a uniform, super-tough fabric. These features give NOVA-TECH Wipes a high degree of absorbency and effectiveness during the process of general wiping. Wipes made with this fabric are processed and double-bagged in a controlled environment.
