Development and Properties of Thermochromic Regenerated Cellulose Fibers and its Fabric

The development of regenerated cellulose fiber and its fabrics with thermochromic effect was introduced, the effects of regenerated cellulosic material on the maturity, viscosity and spinability of regenerated cellulose fiber spinning solution were discussed. The microstructure of fiber was observed by scanning electron microscope, the physical mechanical properties of fiber were analyzed, and the effects of heating time, test temperature and washing times on the discoloration effect of regenerated fiber fabric were discussed. The result show that the addition of the rmochromic microcapsule emulsion has an effect on the maturation and viscosity of the viscose solution. The discoloration effect of fiber fabric is less affected by the heating time and more affected by the temperature.
