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...

Both non-woven and meltblown masks have their own advantages, but in terms of protection, meltblown masks are better. The middle layer of the medical mask is a melt-blown non-woven fabric, which can filter bacteria and viruses in the droplets, and is a kind of ultra-fine electrostatic fiber cloth. The role of masks containing meltblown cloth: The main material of medical masks with virus filtering...

The two masks are not the same, and the two masks look the same. The inner and outer layers are non-woven fabrics, but the meltblown filter layer in the middle is the fundamental difference. From the perspective of the filter layer, medical surgical masks are melt blown filter layers, and disposable masks are non woven fabrics. The meltblown filter layer is obviously more dense, and the material i...

Due to the impact of the epidemic, the demand for melt blown cloth remains high. However, so far, there have been a large number of unqualified melt blown cloths on the market. In order to facilitate enterprises to understand, we briefly summarize several major melt blown cloth testing items: 1. Filtering power The air extracted from the melt blown cloth detected by the particulate detector is equ...

The mask has a three-layer structure. The inner and outer layers are non-woven fabrics, and they are not the same. Generally, the inner layer is made of skin-friendly and soft SSS non woven fabric, which makes it more comfortable to wear. The middle layer of the mask is the meltblown cloth. The strength of the meltblown cloth is not strong, and the thickness is very thin. It can be torn apart by h...

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...

This question is the most frequently asked by mask manufacturers. We have compiled the information and discussed with you what is meltblown electret treatment. Electret refers to a dielectric material with long-term charge storage function. It has the advantages of high efficiency, low flow resistance, antibacterial, and energy saving. On the basis of ensuring the physical collision blocking effec...
