What is melt blowing process?
Melt-blowing is a unique, one-step process in which the melt of a polymer emerging from orifices is blown into super-fine fibres by hot, high-velocity air.
A molten polymer is blown into ultrafine fibres and collected on a rotary drum or a forming belt with a vacuum underneath the surface to form a nonwoven web..
What is a melt blown fabric?
The melt blown process is a nonwoven manufacturing system involving direct conversion of a polymer into continuous filaments, integrated with the conversion of the filaments into a random laid nonwoven fabric.
How do you make a blown melt?
Melt-blown process is a one-step process in which high-velocity air blows a molten thermoplastic resin from an extruder die tip onto a conveyor or take-up screen to form a fine fibrous and self-bonding web. The fibres in the melt blown web are laid together by a combination of entanglement and cohesive sticking.
Is melt blown washable?
In other words, nanofiber filters can be easily sterilized with ethanol at home and reused multiple times.
What is melt blown filter cloth?
Melt-blown process technology. Melt-blown non-woven fabric is a non-woven fabric manufacturing method that melts thermoplastic high polymers such as PP (Poly propylene), and extrusion spinsthrough anozzle.
What is melt blown protection?
The melt blown cartridge filters are cylindrical cartridges made from the finest polymer fibers melt blown and collected over a rotating spindle. The polymer travels through a tubular path and is blown out through the opening and the polymer steam is air dragged to form fibers.
What is PP meltblown?
Melt blown extrusion is a manufacturing process that is used for creating a type of fabric called non-woven fabric which is made from polymers such as polypropylene. … The resulting fabric has a number of desirable properties that include: Absorbency. Bacterial barrier.

What is melt blown non woven fabric used for?
Meltblown cloth has good filterability and can be used with masks to extend the use time of masks, which is convenient and hygienic! Non-woven fabric: Non-woven fabric has the characteristics of waterproof and anti-fog, non-irritating, breathable and soft, etc.
Is interfacing a melt blown fabric?
The closest melt- blown fabric in fabric stores is a product called “interfacing” (e.g., Pellon) which is made of polyester. Fortunately, polyester also repels water, and is also negatively charged – just not as negative as polypropylene.
Is polypropylene fabric the same as interfacing?
Interfacing is normally used to stabilize fabrics when cutting and sewing. “Non-woven” interfacing is usually polypropylene. Interfacing is more typically used as a filter material. Multiple layers of interfacing would be hard to breathe through, making it a poor option for face mask material.
What is melt blown material used for?
Melt Blown Face Mask Filter Material is a type of HEPA (high efficiency particulate air) filter. This 100% virgin polypropylene filtration material can be used for PPE (personal protective equipment) masks and respirators.
Is melt blown nonwoven fabric washable?
Nonwovens generally are not considered wash-durable, and more than a third of nonwovens today are used in durable applications that necessarily do not require laundering since most nonwovens inherently are considered “disposable” after one end-use application.
Can meltblown nonwoven fabric be washed?
The non-woven fabric should be dry-cleaned as much as possible. It is easy to fade after washing. Do not use detergents containing bleach or fluorescence. 2, if you have to wash, soak in cold water, do not expose to the sun, it is recommended to dry.
Is meltblown fabric electrostatic?
From the above understanding of the two materials, we can see that electrostatic cotton can be used in KN100 grade masks, while meltblown cloth is commonly used in various masks, but the filtration efficiency is lower than electrostatic cotton.
