Recycling of mixtures of textiles comprising cellulose

A method for recycling a mixture of textiles comprising natural cellulose fibers and man-made cellulose fibers, said method comprising the sequential steps:

• a. providing at least one textile material, wherein the at least one textile material comprises natural cellulose fibers and man-made cellulose fibers,
• b. mechanically disintegrating the material,
• c. treating the material to swell the cellulose fibers in an aqueous solution during a time in the interval 5 minutes to 24 hours, preferably 20 minutes to 120 minutes, under reducing conditions, wherein at least one reducing agent is present at least during a part of the swelling, wherein the pH is in the range 8-14, wherein the temperature is above 0° C.,
• d. performing at least one oxidative bleach,
• wherein the time for the at least one oxidative bleach in step d) and a concentration of at least one bleaching substance in step d) are adjusted so that the limiting viscosity number as determined by ISO 5351:2010 for the resulting material after step d) is reduced to a value in the interval 200-1200 ml/g.
