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...

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...

Sofa non-woven fabrics are mainly PP spunbonded non-woven fabrics, which are made of polypropylene as the main raw material and are composed of fine fibers. The finished product is soft and moderately soft and comfortable through point hot melt bonding. High-strength, chemical-resistant, anti-static, waterproof, breathable, antibacterial, non-toxic, non-irritating, non-mold, and can isolate the pr...

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 ...

Non-woven fabrics are a environmentally friendly materials. They are breathable, flexible, non-toxic and non-irritating, low in price, and recyclable. Now many factories product PP non-woven fabrics for S and SS, even SSS type. So what is the difference between the PP non-woven S and SS? Next we will introduce it. 1. Structures PP Non-woven S type: spunbond non-woven fabric, which is equal t...

The hydrophilic non-woven fabric makes the non-woven fabric have a certain hydrophilic (water absorption) effect. Generally, PP non-woven fabrics and PET non-woven fabrics can be made with hydrophilic type. So it is widely used. Next, we will introduce the three commonly used products for you. 1. diaper The water-absorbing layer of the upper and inner surfaces are made of hydrophilic non-woven fab...
