Meltblown
Meltblown is a specialized fabric manufacturing process that creates very fine synthetic fibers used in many everyday products. It's like creating a super-fine spider web from melted plastic. This technology is especially important in making protective materials like face masks, air filters, and special cleaning materials. The process involves melting plastic pellets and using hot air to blow them into tiny fibers that form a web-like material. This method is particularly valuable because it creates materials that can filter very small particles while still allowing air to flow through easily.
