The Production Process of Melt Blown Cloth Manufacturers

As a melt-blown cloth manufacturer, SENCI would like to introduce to you based on the actual operation information of the melt-blown cloth factory. The spinning technology mainly includes the melt extrusion rate, hot air speed and melt temperature of the meltblown fabric.

1. Melt extrusion of melt-blown cloth

The extrusion volume of the polymer melt produced by a meltblown fabric factory affects the linear density and yield of the fiber. The higher the grams of polymer melt extruded from the fuse hole per minute, the thicker the fiber. Therefore, on the premise of ensuring fiber fineness, the number of spinneret holes needs to be increased to increase the production value of meltblown nonwovens.

2. The draft speed of the melt-blown cloth

The secondary hot melt flow rate of the process parameters directly affects the fineness of the fiber during the injection process. Polymer melts and a certain amount of melt viscosity for extrusion, higher air-drawing speeds, wire drawing effects, microfluidics for melt spinning polymers?

In industrial production, with the rapid development of information technology, ventilation hot air can be used to compensate for the continuous change of fiber hole diameter caused by the addition of polymer extrusion time, that is, the flow of secondary hot air is necessary with the polymer extrusion phase. match.

3. Melting temperature of melt-blown cloth

The meltblown temperature of the melt blown cloth is the working temperature, which can be used to adjust the melt viscosity of the polymer melt nozzle. The melting temperature is usually higher than the melting point of the PP resin in the viscous active state. When other process conditions are kept constant, the melt viscosity of the polymer decreases and the melt mobility is better.

Thus, microfibers can be easily obtained by melt spraying using high MF polymer flake materials. However, if the melt viscosity of the melt blown non woven fabric factory is too low, it will cause excessive expansion of the melt activity, and the short microfiber form will fly into the air and cannot be collected.
