Analysis of the future development direction of meltblown fabric
Meltblown cloth, commonly known as the "heart" of a mask, is a filter layer in the middle of the mask, which can filter bacteria and prevent the spread of pathogens. Meltblown cloth is a kind of melt blown fabric, which is made of polypropylene with high melt index and high-speed hot air flow to draw the melt flow extruded from the spinneret hole of the die head, so as to form superfine fiber and collect it on the screen curtain or roller, and at the same time, it is self-adhesive The fiber diameter of woven fabric can reach 1-5 microns.
1、 Application of air purification
Melt blown non-woven fabric industry development trend analysis, used in air purifier, as a sub efficient and efficient air filter, and for large flow rate of coarse and medium efficiency air filtration.
It has the advantages of small resistance, high strength, excellent acid and alkali resistance, corrosion resistance, stable efficiency, long service life and low price. There is no short fiber phenomenon of filter material falling off in the purified gas.
2、 Application in medical and health field
It is widely used in hospitals, food processing, mines and other workplaces that need dust and bacteria prevention.
The anti-inflammatory and analgesic film made by special treatment has good air permeability, non-toxic side effects and easy to use. SMS products compounded with spunbonded fabric are widely used in the production of surgical clothes, hats and other health products.
3、 Liquid filter material and battery separator
Polypropylene melt blown fabric is used to filter acid and alkaline liquid, oil, oil and so on. It has been regarded as a good diaphragm material by battery industry at home and abroad. It has been widely used. It not only reduces the cost of battery, simplifies the process, but also greatly reduces the weight and volume of the cell.
4、 Oil absorbing materials and industrial wipes
All kinds of oil absorbing materials made of polypropylene melt blown cloth can absorb 14-15 times of its own weight. It is widely used in environmental protection engineering and oil-water separation engineering. In addition, it can be used as clean material for oil and dust in industrial production. These applications give full play to the characteristics of polypropylene and the adsorption of superfine fibers prepared by melt blowing.
5、 Thermal insulation material
The average diameter of melt blown superfine fiber is between 0.5 and 5 m, the specific surface area is large, and a large number of micro pores are formed in the cloth, and the porosity is high. This kind of structure has a lot of air stored in it, which can effectively prevent heat loss and has excellent thermal insulation property. It is widely used in the production of clothing and various thermal insulation materials.
The new epidemic situation has sounded the alarm for us. In the future, the world will pay more attention to this field of respiratory health. The industry is bound to show explosive growth, and the application prospect of meltblown fabric is immeasurable. Of course, the premise is that the quality must be passed, and good products are the most important guarantee for profits.
