The meltblown cloth is really coming out!Let's follow the meltblown cloth manufacturer to understand:
Meltblown fabric technology originated in the 1950s, when the United States in order to collect radioactive particles in the upper atmosphere to develop ultrafine filtration materials, the development of a molten state of polymer under the action of temperature and air flow, directly produce non-woven fabric technology.
This technology combines the polymer material processing technology of chemical industry and the non-woven material manufacturing technology of textile industry, forming a new technology in the field of materials science to make new and efficient chemical non-woven filter materials.
The raw material of melting spray cloth is polypropylene with high melting index.
The higher the melting index of polypropylene, the finer the fiber is, and the better the filterability of the melt-sprayed cloth is.
Polypropylene is a polymer formed by the addition reaction of propylene.White waxy material, transparent and light in appearance.The density is 0.89 ~ 0.91g/cm3, flammable, melting point is 165℃, softening at 155℃, and the temperature range is -30 ~ 140℃
Under 80℃ can resist acid, alkali, salt solution and a variety of organic solvents corrosion, can be decomposed under high temperature and oxidation.Polypropylene is widely used in clothing, blankets and other fiber products, medical equipment, cars, bicycles, spare parts, transportation pipelines, chemical containers and other production, also used in food, medicine packaging.
