A Design for Spinning Die Channel of Melt-Blown Nonwoven Fabric
This paper has designed the T-channel, the fish-tail channel and the coat-hanger channel, and compared them separately. The conclusion has been obtained, which the coat-hanger channel conforms to the production technological requirement of melt-blown nonwoven fabric. In order to further confirm the coat-hanger channel design, the pressure and speed distribution of flow process which polymer melt flow in the channel have been simulated by ANSYS. The results indicated that the coat-hanger die channel conformed to the design requirement perfectly.
