Cellulose fibre

Cellulose fibres form the main component of the cell walls in plants, which means that cellulose is the most common natural polymer in the world. Fibres that result from a process where cellulose is dissolved and spun again are known as regenerated cellulose fibres. Depending on the manufacturing process, a distinction is made between viscose fibres, lyocell, modal fibres and lenpur. Well-known, protected brand names are TENCEL®, DANUFIL® or ECOVERO®. Slight changes in the chemical and physical parameters during the spinning process can lead to significantly different properties of the regenerated cellulose fibres. Accordingly, the fibres can be designed variably depending on the application area where they are to be used.

Cellulose fibre
Manufacturing process

The oldest process for producing regenerated cellulose fibres is the viscose process. The first step is the use of caustic soda to convert the cellulose into alkali cellulose. The action of carbon disulphide on the alkali cellulose creates xanthate. Together with an aqueous sodium hydroxide solution, this forms the viscose spinning solution. Filtration through precipitation in sulphuric acid and the elimination of carbon disulphide finally forms the finished viscose fibres. In the much more recent and more sustainable lyocell process, cellulose is dissolved in a mixture of N-methylmorpholine-N-oxide (NMMO for short) and water at elevated temperatures. This mixture is wet spun to form the fibres.
