Non Woven Fabric

  At present, the main data of   melt blown cloth   refers to the filtration rate of melt blown cloth, which is mainly divided into 80% particulate matter filtration rate (the following industrial melt blown cloth, the purpose of this melt blown cloth is mainly used for industrial purposes, such as filtration, warmth, isolation, etc. For industrial purposes, this material can also be used to produce dust masks for use in channels where particulate matter is diffused, such as logging plants, furniture factories, and flour mills. Meltblown non woven fabric with a filtration rate of 80%-90% can be used to produce  protective masks . This type of melt blown cloth has transitioned from industrial grade to civilian grade. Melt blown cloth in this filtering range generally only improves filtration efficiency. It does not have a protective effect on special scenes, such as the filtration of blood red blood cells, white blood cells and other molecules. At the same time, the f...

  Regarding the change of the current weather, many people choose to wear masks when they go out. Everyone knows the haze weather. There are many masks on the market for us to use. Then it is the children who are affected by the haze. It is difficult for children to find suitable protective measures. Moreover, there are many different kinds of children's masks on the market, but these masks are all colored. After expert certification, these colored masks have too many hidden dangers. So in order to make suitable anti-haze masks for children, let   mask non-woven fabric manufacturers   will introduce why these colorful masks should be used with caution. The investigation found that there are many kinds of children's masks on the market, and various gimmicks emerge one after another, but there are many hidden dangers. But this kind of mask also cannot prevent PM2.5. For most cartoon colored children’s masks on the market, most of these masks are made of chemical fiber fabri...

  (1) Physical properties:   PP non woven fabric   is a non-toxic, odorless, milky white highly crystalline polymer, which is particularly stable to water, and its water absorption rate is only 0.01% in water for 14 hours. The molecular weight is between 80,000 and 150,000, and the moldability is good. However, due to the large shrinkage rate, the original wall products are easy to dent, the surface of the products has good gloss and is easy to color. (2) Mechanical properties: PP non woven fabric has high crystallinity and regular structure, so it has excellent mechanical properties. Its strength, hardness and elasticity are higher than high-density PE (HDPE). The outstanding feature is the resistance to bending fatigue (7×10^7) times of opening and closing without damage. The coefficient of dry friction is similar to nylon, but it is not as good as nylon under oil lubrication. (3) Thermal performance: PP non woven fabric has good heat resistance, melting point is 164~17...
