Nanocomposites containing different cellulose nanowhisker concentrations (5, 10, and 20 wt%) were applied to woven wool fabric by a pad-dry-cure process. The results indicated that as cellulose nanowhisker concentration was increased from 0 to 20 wt%, the shrinking rate of treated wool fabrics decreased both in warp and weft directions. The existence nanocomposite on wool fabric was confirmed by FT-IR and SEM analyses. Compared with neat SMPU, treatment made with nanocomposite including cellulose nanowhisker enhanced rigidity, tear strength, anti-felting and weight loss performances of the wool fabric after repeated washing cycles.</span><br></p> |
