A process is shown that relates to a process for providing at least one solid fraction from a textile product including a natural fibre and/or a synthetic fibre, wherein the process includes the steps of: i) proving the coloured textile product including a natural fibre and/or one or more synthetic fibres; ii) adding a liquid solution of dihydrolevoglucosenone and/or derivatives of dihydrolevoglucosenone in water, thereby providing a decolorized textile product; and iii) separating the decolorized textile product from the liquid fraction, thereby providing the at least one solid fraction.
