Jinhaocheng professional meltblown nonwoven fabric manufacturer will answer the problem and solution of meltblown fabric hardening and brittleness.
Many melt-blown cloth manufacturers may have encountered this problem: melt-blown cloth becomes brittle and hard overnight after production. At this time, should we use POE toughening or use softener to solve it?The layman watches the scene, the expert sees the way, how to solve the problem of melt-blown cloth becoming hard and brittle quickly and effectively, using Zhejiang dajin new material co., LTD.
The brittleness of meltblown cloth production process may be:
1.The melting finger of PP1500 melt spraying material is high or low.The melting finger is too high, and the material basically has no strength.If the finger is too low, the PP is denatured, it's no longer PP.
2.If the melt-blown equipment is small, the corresponding screw will be short and do 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 brittleness of meltblown cloth after production may be caused by:
1.If the length diameter of the spinneret is relatively small and the hole is thick and short, the fiber ejected by the polymer is thick, the gap is large, and the water absorption is more for a long time, which directly leads to the brittleness of the melt-blown cloth.
2.winding device is too short, will produce waste heat in the process of winding, coupled with no rapid cooling, PP material will naturally be more brittle after crystallization.
3.if the packaging is not sealed with winding film, then the cloth in the subsequent absorption of more moisture, will become brittle.
