| Abstract: | The results of study on thermal properties of acrylic fiber measured by DSC were reported. It was found that the thermal properties were affected by composition and texture of fibers, solvents used and formation method. In order to determine the extent of pre-oxidized reaction of acrylic fiber, the extent of cyclization and the moisture content of pre-oxidized fiber were estimated respectively by DSC and peak heights of DTA curves. All these results can be used to control the pre-oxidized process. |
