Features

Low-dust

Using long fibers with minimal fluff, minimize dust emissions from the wiper itself.

Low residual ions

Pure water cleaning is performed to minimize residual ions. Delivered in clean packs.

Excellent wipe-off effect

The ultra-fine, flat, sharp cross section of Kuraray Co., Ltd.'s proprietary split fiber provides excellent wiping performance due to the edge effect.

Liquid absorption by capillary action

The capillary phenomenon unique to split fibers quickly absorbs water and oil.

High-density machining

Split fibers are knitted at high density and further processed for high shrinkage. Wiper surface is flattened and wiped evenly.

Wide range of chemical resistance

It is virtually impervious to ordinary acids, alkalis, and various organic solvents.

*Organic compounds: Alcohols / Hydrocarbons / Chlorinated hydrocarbons

*Inorganic compounds: Acids and Alkalis / Bleaching agents
