Meltblown cloth(China Meltblown Nonwovens Wholesale) is the best barrier for masks. It is a very fine material. The inside is made up of a lot of crisscross microfibers stacked in random directions. Taking PP as an example, the higher the MFI, the finer the wire drawn during melt-blown processing, and the better the filtration performance.
Hot air jet angle
The hot air jet angle mainly affects the drawing effect and fiber morphology. The smaller angle will cause the fine flow to form parallel fiber bundles, resulting in poor uniformity of the nonwoven fabric. If the angle tends to 90°, a highly dispersed and turbulent air flow will be generated, which is conducive to the random distribution of fibers on the screen, and the resulting melt-blown cloth has good anisotropy.
Screw extrusion speed
Under the condition of constant temperature, the screw extrusion rate should be kept in a certain range: before a certain critical point, the faster the extrusion speed, the higher the melt-blown cloth quantitative, the greater the strength; to exceed the critical value, the melt-blown cloth(Cloth Face Mask Wholesale) Instead, the strength decreases, especially when MFI>1000. It may be because the extrusion rate is too high, which leads to insufficient wire drawing and serious wire, so that the bonding fiber on the cloth surface is reduced, and the strength of the melt-blown cloth is reduced.
Hot air velocity and temperature
Under the same temperature, screw speed, and receiving distance (DCD), the faster the hot air speed, the smaller the fiber diameter, the nonwoven fabric feels softer, and the more fiber entanglement, resulting in a denser and smoother web. Strength increased.
Receive distance (DCD)
Too long acceptance distance will lead to a reduction in longitudinal and flexural strength, bending strength, and a non-woven fabric(Medical Meltblown Filter Manufacturer) with a fluffy feel. In the melt-blowing process, filtration efficiency and filtration resistance will decrease.
Meltblown die head (hard index)
Mold material and process temperature setting. Replaced with some low-end mold steel, there will be some micro cracks that are invisible to the eyes during use, the hole diameter is rough, the precision is poor, and the machine is directly used without polishing. It causes uneven spinning, poor toughness, and different spinning thickness, which is easy to produce crystals.
Net suction
Process parameters such as air volume and wind pressure for suction under the net
Web speed
The net curtain speed is slow, the melt-blown cloth weight is high, and the filtering efficiency is larger. On the contrary, it also holds.
Electret
Electret voltage, electret time, electret molybdenum wire distance, electret environmental humidity, etc. all affect parameters such as filtration quality.
