How to Use Meltblown Nonwoven Fabric
Filtration material
Filtration is to separate the particulate matter dispersed in the gas or liquid, meltblown nonwoven has the characteristics of fine fiber, many pores, and small pore size, used in the field of gas filtration.
Gas filtration: medical masks, indoor air conditioner filtration materials, filter media, etc. In order to improve the filtration effect, the fiber fineness can be reduced and the density of the filter material can be increased, but this will cause a significant increase in infiltration resistance.
The standing level treatment makes the meltblown nonwoven material with static electricity, which can improve its filtration effect through the electrostatic effect.
The meltblown nonwoven withstanding level treatment has the advantage of high filtration effect and low filtration resistance because it has lasting static electricity and can rely on the electrostatic effect to trap fine dust.

Common Industrial Cutting Methods for Meltblown Nonwoven Fabric
Rotary cutting
Industrial rotary cutting machines are usually automated and can cut thick or several layers of nonwovens at the same time. In this process, the material is fed through a machine that uses a rotating circular knife to cut the material into the desired width. The trick for cutting nonwoven with rotary cutting is to have an extra long and sharp grinding on the circular blade.
Razor slitting
Cutting thin nonwovens wrapped on spools is also possible with industrial blades. In this case this is done on a rewinder machine and the material must also be tensioned so that the blade can easily cut through the material. Usually the blade has additional coatings on the cutting edges to improve performance and reduce heat build-up on the blade when cutting.
Plotter cutting
Nonwoven material can be cut by a plotter (cutter / digital cutting system) using a process of CNC cutting. The nonwoven material is placed on the cutter table, where a vacuum holds the material firmly while cutting. An oscillating knife then cuts the material, most often of complex designs and patterns. Digital cutting with a plotter offers a high degree of precision and accuracy, making it well-suited for cutting complex shapes and patterns in nonwoven materials.
Die-cutting
Punching is a process in which a die is used to give nonwovens a specific shape. Dies are special tools made of metal or other materials that are given the desired shape or pattern. The material is placed between the die and a cutting press. Pressure is applied to give the material the required shape. Die-cutting can also include cutting with straight serrated / toothed knives, which technically perform a similar action - a sharp vertical movement cuts the material, cutting off the desired length.
Ultrasonic cutting
An ultrasonic cutting machine cuts non-woven materials by applying ultrasonic vibrations to a cutting knife. It is a fast and accurate cutting method that can be used to cut complex shapes and patterns. The ultrasonic knife cutting technique is similar to cutting with an oscillating knife, only the speed of the knife is hundreds of times faster.
Laser cutting
Laser cutting involves the use of a high-powered laser to cut through nonwoven materials. In the manufacture of medical and hygiene products such as surgical masks and gowns, laser cutting is commonly used.
Materials Used in Meltblown Nonwoven Fabric
Synthetic polymers
These are the most common materials used to make nonwovens. Examples include polypropylene (PP), polyester (PET), polyethylene (PE) and nylon.
Natural fibers
Nonwovens can be made from natural fibers such as cotton, wool and viscose.
Recycled materials
Nonwovens can also be made from recycled materials, such as recycled PET bottles, which can be melted down and spun into fibers.
Blends
Nonwovens can be made by blending different types of fibers, such as a blend of synthetic and natural fibers, to achieve specific properties.
Traditional Process of Non Woven Meltblown Fabric Production
Input polymer → melt extrusion → fiber formation → fiber cooling → web forming → bonding (fixed web) → trimming and winding → finishing or special finishing
Input polymer—PP polymer raw materials are generally made into small spherical or granular slices, poured into a barrel or hopper, and fed into the screw extruder.
Melt extrusion—At the feed end of the screw extruder, the polymer chips should be mixed with stabilizers, brighteners and other additives and necessary raw materials such as masterbatch, and then enter the screw extruder after being fully stirred and mixed, and heated at high temperature Become a melt, and finally the melt is sent to the spinneret by the metering pump through the filter. In the melt blown process, the general extruder also uses its shearing and thermal degradation effects to reduce the molecular weight of the polymer.
Fiber formation—The filtered clean melt will pass through the distribution system, and then evenly sent to each group of spinnerets, so that the extrusion volume of each spinneret hole is consistent. The spinneret of meltblown fiber is different from other spinning methods, the spinneret holes must be arranged in a straight line, and the upper and lower sides have high-speed air jet holes.
Fiber cooling—A large amount of room temperature air is sucked in at the same time on both sides of the spinneret, mixed with the hot air stream containing ultra-fine fibers to cool it down, and the molten ultra-fine fibers are cooled and solidified.
Netting—In the production of meltblown fiber nonwovens, the spinneret can be placed horizontally or vertically. If placed horizontally, the superfine fibers are sprayed on a circular collecting drum to form a web; if placed vertically, the fibers fall onto a horizontally moving web forming curtain to condense into a web.
Adhesion (fixed net)—The self-adhesive reinforcement mentioned above is sufficient for some applications of melt blown cloth, such as: the fiber net is required to have a relatively fluffy structure, good air retention rate or porosity Wait. For many other applications, self-adhesive reinforcement alone is not enough. Hot-roll bonding, ultrasonic bonding, or other reinforcement methods are also required.
How to Clean Meltblown Nonwoven Fabric
Meltblown nonwoven fabric will produce stains after a long time of use. However, due to the particularity of non-woven materials, special attention should be paid to the cleaning of meltblown nonwoven fabric. Soaking method: soak the meltblown nonwoven fabric with cold water or warm washing powder for 10-20 minutes. The time should not be too long, because the non-woven materials are easy to be decomposed by water for a long time. Please do not use washing products containing bleaching or fluorescence, Prevent meltblown nonwoven fabric from fading. Gently wash by hand. When cleaning, it is recommended to wash by hand gently, and the effect is better. You can't brush with a brush. The meltblown nonwoven fabric will be easy to fluff, and the meltblown nonwoven fabric will be very ugly. If you want to clean quickly, it is recommended that you choose a soft brush, rub it gently with your hand, and then brush it with a soft brush. It should be light, because meltblown nonwoven fabric break easily.
Cleaning the meltblown nonwoven fabric according to the above method can not only ensure that the meltblown nonwoven fabric can be well cleaned, but also will not affect the appearance of the meltblown nonwoven fabric. The meltblown nonwoven fabric that has been used can still be used like a brand-new one. The application of meltblown nonwoven fabric in clothing is very many, we can make meltblown nonwoven fabric into clothing, also can make meltblown nonwoven fabric into mask and non-woven bag and so on.
