AI Technical Summary
Technical Problem
Regenerated cellulose fibers exhibit significant shrinkage and swelling due to their high hygroscopicity, making them difficult to wash and maintain dimensional stability, particularly in woven or knitted fabrics.
Method used
A treatment method involving the adsorption of cellulose nanofibers (CNF) onto the surface of regenerated cellulose fibers, followed by drying and optionally coating with a resin, to physically constrain the fibers and inhibit swelling and shrinkage.
Benefits of technology
The method significantly reduces shrinkage and swelling of regenerated cellulose fibers and fabrics, maintaining dimensional stability and improving tear strength through the entanglement and cross-linking effects of CNF.
