热历史对涤纶长丝熔融的影响

The effects of thermal history on the melting behaviors of polyester filament

通过调节平牵机的热盘和热板温度,得到了一系列热历史不同的涤纶长丝,应用差示扫描量热法(DSC)研究了热历史对其熔融的影响,同时利用逐次逼近法进行回归并给出了回归方程.

Through adjusting the temperature of hot dish and hot plate on paralleldrawing machine, a series of polyester filaments with different thermal history were obtained. Then, effects of thermal history on melting of those samples were studied by using differential scanning calorimeter (DSC) . At the same time, through adoptinggraduallyapproach regression method, the regression equations were given.
