Preparation and Properties of Phase Change Microcapsules/SMS Intellectualized Thermoregulation Fabrics
Aiming at the thermo-regulating property of textile fabric treated by phase change microcapsules with different concentrations,a kind of phase change microcapsule based on n-octadecane core and melamine-ureaformaldehyde shell was synthesized by in situ polymerization method,and its surface morphology and particle size distribution were subsequently studied by scanning electron microscopy (SEM).Then thermoregulation fabrics were prepared from SMS fabrics,which were treated by phase change microcapsules with different concentrations by a pad-drycure process.The treated fabrics were evaluated in terms of the surface morphology,thermal properties and thermoregulating properties,with respect to the add-on of microcapsules.The properties of the treated fabrics were characterized by means of SEM,infrared thermometer,air permeability tester and tensile tester.The results indicated that the surfaces of microcapsules were smooth,and the particle size distributed evenly.After treated by MPCMs,the rates temperature rise and fall of the treated fabric decreased,which demonstrated excellent thermoregulation capability.Moreover,both of the breaking strength and breaking elongation were increased.The air permeability of the treated fabrics decreased,but the serviceability was little affected.
