The manufacturer of PP Spunbond machine said that many people don't know why the melt-blown cloth becomes hard and brittle. Today, I will take you to understand the problem and solution of the melt-blown cloth becoming hard and brittle.

good price and quality PP Spunbond machine in china
The brittleness of the meltblown cloth production process may be:
1. The melt index of PP1500 meltblown material is high or low. If the melting index is too high, the material basically has no strength. The manufacturer of PP Spunbond machine tells you that if the melt index is too low, PP will be denatured and will no longer be PP.
2. If the meltblown equipment is small, the corresponding screw will be relatively short, and it will not have the function of mixing. The material can only be melted by heating, and the high temperature will degrade the material and cause the meltblown cloth to become brittle.
The reason why the meltblown cloth becomes brittle after production may be:
1. The manufacturer of PP Spunbond machine tells you that if the long diameter of the spinneret is relatively small, and the holes are thick and short, the fibers ejected from the polymer will be thick, the gaps will be large, and the water will be absorbed for a long time, which will directly cause the melt blown cloth to become brittle.
2. If the winding device is too short, waste heat will be generated during the winding process, and without rapid cooling, the PP material will naturally be brittle after crystallization.
3. The PP Spunbond machine manufacturer tells you that if the packaging is not wrapped with a sealing tape, the cloth will become brittle when it absorbs a lot of water.
