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...

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...

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...

Disposable towel is a cotton towel made of 100% pure natural cotton. Because it is produced by advanced cotton spunlace non-woven technology and then processed by high pressure steam sterilization, it is soft, delicate, absorbent. It is a new environmentally friendly alternative to paper towels, cotton pads, face towels and other products. Disposable face towels are at least cleaner than towels an...

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...

Medical non-woven packaging materials are generally SMS non-woven fabrics. The main material of this non-woven fabric is polypropylene, which is processed through multiple processes through meltblown and spunbond processes, and the microstructure is fine plastic fibers. Shrinkage after being exposed to high temperature is a characteristic of plastic items. There is no plastic that is truly resista...

The melting point of PP non-woven fabric is generally between 165-170 degrees, and its decomposition temperature is about 350 degrees. Products can be sterilized at temperatures above 100°C. Under no external force, it will not deform at 150 °C. PP non-woven fabrics are extremely heat-resistant and corrosion-resistant. Its strength, rigidity and transparency are much better than other materials, a...

Meltblown cloth is the key material of masks. Meltblown cloth mainly uses polypropylene as the main raw material. Different countries have different standards of the meltblown,and testing method. As key filter material of mask, our meltblown can reach the standard as below: **3-ply surgical mask: European standard: EN 14683 type I / type II / type IIR; American standard: ASTM F2100 level 1/ l...

Elastic non-woven fabric has soft texture, environmental protection, non-toxic, breathable, natural bacteriostasis and other advantages. It is elastic not only in one direction, but also in both directions.That is particularly suitable for use as the ear hook material of masks. The elastic ear loop non-woven fits our face more closely and is very convenient and comfortable to wear, so the ela...
