1. Raw materials Melt-blown PP is modified on the basis of ordinary PP. After modification, PP has higher melt fat and stable fluidity, while ordinary PP melt has uneven fluidity, and some excessive drafting may easily cause agglomerate polymerization. It makes the fiber thickness uneven and affects the air permeability and filterability of the meltblown cloth. 2. Production process Melt-blown clo...

We know that melt blown cloth is the core material on protective equipment such as masks and plays a major filtering role. In order to achieve effective filtration, the melt blown cloth needs electrostatic electret treatment, in which case droplets etc. will be adsorbed on the melt blown cloth. So if there is static electricity on the meltblown cloth, will it exist for a long time, or is it said t...

The water electret is an electret process for making the meltblown cloth electrostatically charged during the production of the meltblown cloth. The process can be that the meltblown cloth is saturated with static electricity and the electrostatic electret time is long. The reason why melt blown cloth has higher filtration efficiency is because it adds electrostatic electret technology in the prod...

There are 32 flow and 85 flow in the melt blown cloth detection parameters. What does this parameter mean? The quality of melt blown cloth mainly depends on the particle filtration and bacterial filtration efficiency. The specific filtration efficiency of melt blown cloth needs to be tested with a melt blown cloth testing instrument. The specific process will not be introduced in detail, but I wil...

The main color of PP polypropylene is white and transparent, and the products are made all white. What is black meltblown and how is it made? There are actually different ways to achieve black meltblown non woven fabric: One way is to add black masterbatch, which is achieved by adding carbon black. If it is used on the face mask, then need to add the environmental protection carbon black, and the ...
