Question

Question: Why is there a black spot impurity problem in Modified PP Resin for Melt-blown Nonwoven Fabric?

Meltblown cloth enterprises know that if there are impurities in the material, it is easy to block the spinneret hole in the production of meltblown cloth, break the silk, increase the frequency of dismantling the spinneret, and poor uniformity of the cloth surface. Most domestic enterprises producing meltblown PP production line used to do other modified materials, especially when you do some enhanced modified materials, you must add glass fiber or carbon fiber, the high hardness of these fibers, the inner wall of the barrel and the surface of the screw scratched is scarred, there are countless small pits, which is called pockmark. Plastic into these small pits, can not come out, after a lot of time in the heat, there is carbonization, which forms a black spot in the material. Especially when the customer's nozzle is 0.1, it is easy to be blocked. Customers have to change the screen frequently. The customer's feedback is that our Modified PP Resin for Melt-blown Nonwoven Fabric does not block the spinneret holes, which greatly reduces the frequency of removing their spinnerets and increases the output of meltblown fabric.
