Origins
BEMCOT cleanroom wipers are produced from Bemliese,the
100% pure “cupro” cellulosic nonwoven derived from cotton
linter-the fine,downlike fiber that naturally protects and
cushions the seed of the cotton plant.
Cotton 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.
An ISO 9001 certified production facility located at Nobeoka
City in Japan.
Production Process
1. Linter refining
Multistage refining and purification of the cotton linter by steaming and washing.
2. Linter dissolution
Highly purified linter dissolved in a fine, pure, specially formulated spinning solution.
3. Filament spinning
Extrusion of the spinning solution from multi-orifice dies, to obtain multiple continuous filaments
4. Nonwoven sheet formation
Layering of the mutually self-bonding continuous filaments onto a mesh conveyor, to obtain nonwoven sheet without binder.
5. Rinsing, drying, roll winding
Mesh conveyor transport of the nonwoven sheet through water rinse and thermal drying, followed by take-up and roll winding.
The result is the fine, pure Bemliese nonwoven fabric, produced and processed in a clean plant environment, with a broad range of fabric patterns for optimal performance in specific fields of application.
Important features
•Free of binder
•Each continuous filament is self-bonded
