Low particle generation- fallen fibers
Fallen fibers are one of two basic categories of particles which may be generated
in wiper use. They are 100um or more in length, and thus visible to the humban eye.
The other category comprises microparticles, which may be classified as either "airborne"
or "liquid".
High absorbency
Bemcot absorbs some 13 times its own weight in water, as its uniquely structured
cellulosicfilaments are themselves absorbent - in marked contrast to the effectively
non-absorbent synthetic filaments of other wipers.
ISO 9001 Certified
Bemcot cleanroom wipers are produced from Bemliese, the 100% pure "cupro" cellulosic
nonwoven derived f rom cotton linter-the fine downlike fiber that natturally protects
and cushions the seed of the cotton plant. Cottton linter from around the world
is transformed to pure cellulosic nonwoven sheets in an integrated process unique
to the Bemliese plant of Asahi Kasei Fibers. Corporation located at Nobeoka City
in Japan, an ISO 9001 certified production facility.
High chemical resistance
Asahi Kasei test: Typical Bemcot or other competitive wiper immersed in solvent
for 1 day, solvent then evaporated and resudual extracts measured and expressed
in parts per million parts solvent.
High heat resistance
The constituent cellulosic filaments of Bemcot-Inlike polyester, nylon, and other
synthetic filaments -are inherently heat resistant and thus enable effective use
of Bemcot wipers at higher temperatures.
High Purity
No additive, oil or binder is used in the Bemcot nonwoven sheet, production process.
It is therefore extremely low in impurities transfer to the wiped surface, even
under exposure to solvents.
Ecoefficiency
With its recognized ecoefficiency in origins, production, use, and disposal, Bemcot™
can help support green-procurement programs.
