China is the world's major consumer of melt-spraying non-woven fabrics, with the consumption per capita of melt-spraying non-woven fabrics exceeding 1.5kg. Although there is still a gap between China and developed countries such as Europe and the United States, the growth rate is obvious, which also indicates that China's melt-spraying non-woven fabric industry has further space.
Due to the high purchase price of equipment and high production and operation cost, the high price of molten spray products, together with the lack of understanding of product performance and use, make the molten spray market can not be opened, and the related enterprises are struggling, struggling to operate.The following is the development trend analysis of melt-spray non-woven fabric industry.
Melt-sprayed non-woven cloth is the "heart" of surgical masks and N95 masks.The analysis of melt-spraying non-woven fabric industry indicates that the more important melt-spraying non-woven fabric for medical masks has fewer enterprises to provide
China's melting spray nonwoven manufacturing has two types of continuous and intermittent, continuous production line is mainly imported melting spray die head, the other parts of the assembly line by the enterprise itself. With the improvement of China's manufacturing level in recent years, domestic melting spray die head has gradually gained more market share.The development trend of melt-spray nonwoven fabric industry is analyzed from five major applications.
1. Application in air purification field
Development trend analysis of melt-spray non-woven fabric industry, used in air purifiers, as a sub-high efficiency, high efficiency air filter core and used for coarse and medium efficiency air filtration of large flow rate.
It has the advantages of low resistance, high strength, excellent acid and alkaline resistance, corrosion resistance, stable efficiency, long service life and low price.There is no short fleecy phenomenon of filter material falling off in the purified gas.
2. Application in the medical and health field
The dustproof mouth made of melting and spraying cloth has low respiratory resistance, no stuffy air, and dustproof efficiency up to 99%. It is widely used in hospitals, food processing, mines and other work places that need dustproof and bacteria-proof.
The product is made of anti-inflammatory and analgesic film after special treatment, with good air permeability, non-toxic side effects and easy to use. SMS products combined with spunbonded cloth are widely used in making surgical clothes and hats and other sanitary products.
3. Liquid filtration materials and battery diaphragm
Polypropylene melting spray cloth is used to filter acid and alkaline liquid, oil, oil and other excellent performance, has been regarded as a good membrane material by the battery industry at home and abroad, and has been widely used, not only reduce the battery cost, simplify the process, and greatly reduce the weight and volume of the battery.
4. Oil absorbing materials and industrial wiping cloth
All kinds of oil-absorbing materials made of polypropylene melting and spraying cloth can absorb oil up to 14-15 times of its own weight. They are widely used in environmental protection engineering and oil-water separation engineering. In addition, they can be used as clean materials of oil and dust in industrial production.These applications give full play to the properties of polypropylene itself and the absorbability of the ultrafine fiber produced by melting and spraying.
5. Thermal insulation materials
The average diameter of molten jet ultrafine fiber is between 0.5 and 5m, and the specific surface area is large. A large number of micro pores are formed in the cloth, and the porosity is high.This structure stores a large amount of air, can effectively prevent heat loss, has excellent heat preservation, is widely used in the production of clothing and a variety of thermal insulation materials.
The development trend analysis of melt-spraying non-woven fabric industry, such as leather jacket, ski jacket, cold clothing, cotton village cloth, etc., has the advantages of light weight, warmth, no moisture absorption, good air permeability, no mildew.
In the fight against the epidemic, melt-sprayed non-woven fabrics have demonstrated excellent protection and isolation functions, gained the re-recognition and favor of the market, and led to a big expansion.
