The production process of Meltblown Non Woven Fabric involves several steps:
1.Polymer Preparation: Thermoplastic polymers such as polypropylene are melted and prepared for extrusion.
Extrusion: The molten polymer is forced through a spinneret, which contains many small holes or nozzles. This process creates continuous filaments of ultrafine fibers.
2.Fiber Formation: High-velocity hot air or gas streams are directed at the extruded filaments, causing them to rapidly cool and solidify. Simultaneously, the air or gas stretches and attenuates the filaments into much finer fibers.
3.Fiber Collection: The fine fibers are collected onto a conveyor belt or drum as a randomly laid down web. This web forms the basis of the Meltblown Non Woven Fabric.
4.Bonding (Optional): Depending on the application, the Meltblown Non Woven Fabric may undergo additional bonding processes such as thermal bonding, mechanical entanglement, or chemical bonding to improve its strength and integrity.
5.Finishing: The finished fabric may undergo further processing steps such as calendering, embossing, or coating to enhance specific properties or improve surface characteristics.
Overall, the Meltblown Non Woven Fabric production process is highly controlled and precise, resulting in a fabric with fine fibers and unique filtration properties suitable for various applications, including medical masks, air filters, and absorbent products.
