Abstract
In this work, a phase change material was synthesized from diphenyl methane diisocyanate and polyethylene glycol. Phase change material and polyester masterbatches were blended and granulated by a twin-screw extruder to make blend master batch. According to the result of FTIR, no transesterification reaction was found between phase change material and polyester. Process flow of melt spinning was determined by the results of DSC. The addition of phase change material did not have a big impact on spinnability. Thermo-regulated polyester fibers were prepared by melt spinning. The masterbatch of thermo-regulated polyester has a good fiber forming property. Thermo-regulated polyester fiber has a good storage phase change thermal function. Due to the addition of phase change material, the single fiber strength of polyester was decreased and the elongation at break was improved slightly. The thermo-regulated polyester and polyester had the essentially the same moisture regain and hand feel.
