Cellulose Reshaping
Ionic Liquids release nature’s abundant supply of building blocks, gently dissolving them without alternating the primary structure of the original molecules. New bio-based materials can be formed. proionic’s experience includes not only cellulose, but also other biopolymers like hemicellulose, lignin, chitin, chitosan.

Ionic Liquids gently dissolve cellulose
Ionic Liquids are suitable for a wide range of bio-based polymers
Ionic Liquids only split hydrogen bonds in biopolymers but do not affect or deconstruct the biopolymers’ primary structure, which leads to a mild and gentle dissolution. No further chemicals or additives need to be added during processing.
This mechanism works for various types of raw materials. Cellulosic or lingo-cellulosic feedstocks, including agricultural and forestry waste, switchgrass, sorghum, poplar, rice and wheat straw, miscanthus, corn-stover bamboo, paper pulp or cotton, are currently used.
For reshaping an anti-solvent like water is added to the Ionic Liquid solution, triggering the reformation of cellulose’s hydrogen bonds.
Cellulose Reshaping specials
01
Ionic Liquids offer favorable physico-chemical properties
Ionic Liquids have negligible vapor pressures, being non-flammable and non-boiling, even at high temperatures. Ionic Liquids are ideal biomass-solvents due to their high gentle dissolution capacity,, high recycling rates and low toxicity.
02
High molecular weights are retained
In contrast to other cellulose fiber producing processes, using Ionic Liquids as solvents results in remaining high molecular weight of the cellulose. This enables multi-recyclable cellulose filaments with higher stability.
03
Environmentally friendly processes
When using Ionic Liquids biopolymer dissolution, no addition of hazardous, flammable or odor-intensive chemicals (e.g. CS2) is necessary. The Ionic Liquid-based process also requires only a fraction of tquantities of water typically needed in such a process.
Water and Ionic Liquid are recycled and used for a new process cycle. Products from Ionic Liquid-based processes are free of harmful substances.
Key benefits
01
green production process
Ionic Liquids are used as direct solvents. No harmful additives are required. Only water and Ionic Liquids are needed and both can be recycled.
02
non-flammable
Due to absence of a boiling point and negligible vapor pressure Ionic Liquds are non-flammable.
03
non toxic
proionic’s standard Ionic Liquids solvents do not release any gaseous compounds into the atmosphere. Some proionic Ionic Liquids are already OEKO-TEX® ECO PASSPORT certified.
04
no ATEX
Ionic Liquids are non-flammable, resulting in safe and user-friendly production processes and lower investment cost for related equipment.
05
low side reactions
Cellulose in Ionic Liquids shows a low reactivity. No stabilizers or anti-oxidants are needed, contributing to even higher process-safety.
06
no fibrillation
Ionic Liquid-refined fibers are of very high lengths and do not fibrillate on their surfaces.
