Abstract
The present invention provides recycled cellulose-based fibers dimensionally stabilized by the reduction of shrinkage after washing in water or the like. The recycled cellulose fibers have an adsorbate on a surface thereof, in which the adsorbate contains cellulose nanofibers.
Claims4
An anti-shrink processing method for recycled cellulose fibers, the method comprising:
- a cellulose nanofiber adsorption step of immersing recycled cellulose fibers in a cellulose nanofiber dispersion in which cellulose nanofibers are dispersed, such that the cellulose nanofibers are adsorbed onto the recycled cellulose fibers;
- a drying step of drying the recycled cellulose fibers onto which the cellulose nanofibers are adsorbed;
- and
- a resin adsorption step of immersing the recycled cellulose fibers in a solution containing a resin component after the drying step.
