| abstract |
Fabrics comprising regenerated cellulose fibers and a nanoparticle dispersed throughout the fabric are disclosed herein. The regenerated cellulose fibers can be derived from a biomass such as a fibrous cellulose, wood pulp, cotton, paper, bast fiber, bagasse, or a combination thereof. The nanoparticle included in the fabric can be chosen to confer a desirable property, such as a thermal insulating property, to the fabric. Methods of making the fabrics comprising the regenerated cellulose fibers and nanoparticle are also provided. The method can include (a) at least partially dissolving a cellulose substrate in a medium comprising one or more ionic liquids; and dissolving or suspending a nanoparticle in the medium; (b) recovering a solid nanoparticle-modified regenerated cellulose material comprising the cellulose substrate and the nanoparticle; and (c) processing the solid nanoparticle-modified regenerated cellulose material to form the fabric. |
