Regenerated ‘virgin’ cellulose fiber from cotton waste

SaXcell, an abbreviation of Saxion cellulose, is a regenerated virgin textile fiber made from chemical recycled domestic cotton waste. The process to transfer domestic cotton waste into SaXcell fiber is a crucial step in the circular textile chain.

Image Description

SaXcell production starts with sorting domestic cotton textile waste into an as pure as possible, well-defined waste stream. The sorting can be done by hand as is customary now, or with the Identitex (a technique still in development).

Image Description

Next, the pure waste stream is grinded and non-textile components like zippers, nails and buttons are removed. The result is a dry mixture of textile fibers with different fiber lengths. All fiber lengths, long and short, are suitable as raw material for SaXcell.

Image Description

The dry mixture exists of different colours and is chemically decoloured and made suitable for the wet spinning process. Wet spinning can be done according Viscose or Lyocell processes. This means that the new fiber can be produced with few adjustments in the settings of machines on existing installations in Europe and Worldwide.

The end product of this step is SaXcell, a regenerated virgin cellulose fiber. The fiber can be cut to specified lengths, spun into yarns and woven or knitted into fabrics. Colouring can take place at the fiber, yarn or fabric.
