Many melt-blown cloth factories may have encountered this problem: the melt-blown cloth becomes brittle and hard overnight after production. At this time, should we use POE to toughen or use a softener to solve it?
The production process of melt blown cloth factory price may become brittle:
1. The melting index of PP1500 meltblown material is higher or lower. The melting index is too high, and the material basically has no strength. If the melting index is too low, PP will be denatured and will no longer be PP.
2. If the melt blown equipment is small, the corresponding screw will be relatively short and does not have the mixing function. The material can only be melted by heating, and the high temperature will degrade the material and cause the melt blown cloth to become brittle.
The reasons why meltblown cloth becomes brittle after production may be:
1. If the long diameter of the spinneret is relatively small, and the holes are thick and short, the polymer jetted fiber will be thick, the gap will be large, and the time will absorb more water, 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 there is no rapid cooling, the PP material will naturally be more brittle after crystallization.
3. If the packaging is not sealed with stretch film, the cloth will become brittle if it absorbs a lot of water later.
In response to this phenomenon, we focused on research and found a masterbatch that has the characteristics of low odor, high fat solubility, good toughening effect, and high elongation at break. It is compatible with melt-blown PP. The addition ratio depends on the situation. set. It can effectively solve the problems of brittleness and hardening of the melt blown cloth, make the surface of the melt blown cloth smoother and softer, and improve the tensile strength and tear strength.
