Abstract
To improve the ultraviolet resistance and color fastness of the cotton fabrics, a new multifunctional finishing agent of waterborne polyurethane containing UV absorption group (WPUUV) was synthesized and characterized with 1HNMR and UV spectroscopy. Stability of WPUUV and their finishing performance on cotton fabrics were investigated. Results showed that the various color fastnesses such as the dry and wet rubbing fastnesses, wrinkle recovery angle and softness of the dyeing cotton fabrics were obviously improved by WPUUV, which provided good UV protection function for dyeing cotton fabrics as well.
