It is well known that meltblown cloth is the core material of masks. The main material of meltblown cloth is polypropylene.Porous, fluffy structure, good anti-wrinkle performance and so on.Ultra-fine capillary fibers have a unique capillary structure, which increases the unit area and surface area of the fiber.Therefore, melt-blown fabric has good filtration, heat insulation and oil absorption properties.Why is the meltblown cloth called the heart of the mask?Jinhaocheng meltblown cloth manufacturer will take you to know:
The meltblown cloth is called a mask for the heart
The special material for melt-blown fabrics is PP with a high melt index.Thawing index is the mass of melting through standard capillary tubes every 10 minutes.The larger the value, the better the fluidity of the material processing.The higher the melt index is, the finer the polypropylene melt-blown fiber is, and the better the filtration performance of the melt-sprayed fabric is.
Maybe many people don't understand.Take an ordinary medical mask for example. According to national production standards, it contains at least three layers of non-woven fabric, with a key layer of melt-blown fabric in the middle.
The meltblown cloth, often called the "heart" of the mask, is the middle filter layer of the mask.It filters bacteria and stops them from spreading.Its fibers are only one-tenth the diameter of a hair.Although the raw material used is polypropylene, the melt is in the production process.And in special materials used in spraying and other nonwovens, their properties vary greatly.
So besides making masks, what are the uses of meltblown cloth?
Clothing: The main uses of melt-blown fabrics are disposable industrial clothing, insulating materials and synthetic leather substrates.
Oil Absorbent: Fused spray fabrics usually use lubricants in water, such as accidental leaks of lubricants.In addition, it can also be used in machining shop or factory liner.
Melt blown nonwoven fabric for mask
Electronics: Meltblown cloth is sometimes used to insulate batteries and capacitors.
Melt blown filter filtration: applications of melt blown filter include surgical masks, liquid filters, gas filters, cartridge filters, clean room filters, etc.
Medical fabrics: The largest market for melt-blown nonwoven fabrics in the medical market is disposable cotton clothing, gauze, and disinfecting kits.
Sanitary products: Meltblown fabrics are often used in women's sanitary napkins, diapers, and adult disposable incontinence products.
Other: space cotton, heat preservation and sound insulation material, smoke filter, tea bag bag, etc.
