Novel Cellulose/Polymer Blend Fibers Obtained Using Ionic Liquids

Combinations of cellulosic fibers (cotton, viscose) with man-made chemical fibers (polyesters, polyamides, or polyacrylonitrile) are common as composites in textile fabrics. In this work the preparation of cellulose/polymer blend fibers in ILs is described. Cellulose is solved in ILs with other fiber polymers such as polyamides or PAN and processed to fiber blends by wet spinning. The rheology of spinning dopes, structural parameters, and physical textile properties of the prepared fibers are determined. TGA indicates a significant increase of carbon yield of the cellulose fibers blended with m-aramide and PAN, respectively.
