Regeneratedcellulose from cotton waste
SaXcell, an abbreviation of Saxion cellulose, is a regenerated virgin textile fibre made from chemical recycled domestic cotton waste. The process to transfer domestic cotton waste into SaXcell fibre is a crucial step in the circular textile chain.
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).
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 fibres with different fibre lengths. All fibre lengths, long and short, are suitable as raw material for SaXcell.
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 fibre 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 fibre. The fibre can be cut to specified lengths, spun into yarns and woven or knitted into fabrics. Colouring can take place at the fibre, yarn or fabric.
Air-gap spinning: 1,7 dtex, fiber length: 38 mm
Strength: 43 cN/texstronger than cotton and other regenerated fibers
Dye efficiency: higher that expected
