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.
Claims8
Recycled cellulose fibers comprising:
- an adsorbate on a surface thereof,
- wherein the adsorbate contains cellulose nanofibers.
An anti-shrink processing method for recycled cellulose fibers 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;
- and
- a drying step of drying the recycled cellulose fibers onto which the cellulose nanofibers are adsorbed.
