Abstract:
The present invention relates to a method for predicting the break-up possibility of a synthetic resin filament in a melt blowing process from the rheological properties of the synthetic resin. According to the present invention, a method that is capable of predicting the break-up possibility of the synthetic resin filament in the melt blowing process for preparing a filament using the synthetic resin in advance, through the measurement of the rheological properties of the synthetic resin, is provided.
