Regenerated ‘virgin’ cellulose fiber 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.

SaXcell Fibers

Air-gap spinning: 1,7 dtex, fiber length: 38 mm

Strength: 43 cN/tex

stronger than cotton and other regenerated fibers

Elongation: 13%


Good dyeability

Dye efficiency: higher that expected

Cotton Recycling

Chemical recycling Mechanical recycling
Length of waste fibers not important important
Composition of waste fibers separation needed to obtain cellulose with a high purity yarn spinning is effected by composition
Quality of produced fibers high low/medium
Color of produced fibers white depends on the waste
Products with 100% recycled fibers possible? yes, high value no, (lower value)
Costs medium/high low/medium
