Abstract：To study the effects of different binders on the performance of thermo-regulated textile fabric, phase change microcapsules were prepared using urea modified melamine resin as wall material and n-octadecane as core material through the in-situ polymerization method. The surface morphology and size distribution of the microcapsules were studied by scanning electron microscopy (SEM). Then, waterborne polyurethane and polyacrylate were added into the microcapsule finishing solution, the cotton fabric were treated by two different finishing solutions. SEM, DSC, infrared thermometer, washability and mechanical properties were tested. The results showed that the phase change microcapsulated fabric treated with different binders reduce the rate of heating and cooling in the process of changing the external environment, and had excellent temperature regulation function. The surface of the fabric treated by polyacrylate was more compact and smooth, and the enthalpy of melt phase transition was 30.57J/g, which had announced effect on the heat storage and temperature regulation, better washability and mechanical properties, and thus better performance.
