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...

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 ...

Now the face mask is as a daily necessary product for people’s life since the covid-19 broke out. Usually we use the normal type mask for the out layer of white, blue, and some masks are green and black color non woven fabric. It is very comment. Do you want to buy the special designed of the mask? When the people see you, they will recognize you at once. You can see the following pictures of spec...

The elastic non-woven fabric is a brand-new non-woven product, which breaks the situation that the film elastic is not so breathable, too tight and little flexibility. Elastic non-woven fabric is a non-woven fabric that can be stretched horizontally and vertically. The elasticity is due to the addition of elastic masterbatch. The elastic non-woven fabric is produced with PP medical grade material,...

Meltblown non woven fabric use polypropylene as the main raw material, and the fiber diameter can reach 0.5-10 microns. These ultra-fine fibers with unique capillary structure increase the number and surface area of fibers per unit area, so that the meltblown cloth has good air filtration. , is a relatively good mask material. In large, medium and small medical institutions, in disaster-stricken a...
