Primary Industrial Verification of the Polymer Air Drawing Model for the Melt Blowing Nonwoven Process

摘要

Nonwoven samples are collected from industrial equipments in four nonwoven factories. The processing parameters and equipment parameters are also obtained. The fiber diameters of the nonwoven samples are measured by using the image analysis method and compared with the predicted fiber diameters by solving the polymer air drawing model. The results show that the predicted fiber diameters coincide with the measured fiber diameter very well, which confirms that the polymer air drawing model is effective in predicting fiber diameters of nonwoven fabrics produced by industrial equipments in nonwoven factories. The results reveal the practical value of this theoretical research on the melt blowing technology.
