Melt blown non-woven fabrics are mainly used to filter micron sized particles such as dust, microorganisms, and haze, and can be called the "heart". The polypropylene ultrafine fibers are randomly distributed and adhered together, with a clean, smooth, and soft appearance. The material has a fiber fineness of 0.5-1.0 microns, and the random distribution of fibers provides more opportunities for thermal bonding between fibers, resulting in a larger specific surface area and higher porosity (≥ 75%) for melt blown gas filtration materials. After high-voltage electret electrostatic treatment, it has the characteristics of low resistance, high efficiency, and high dust tolerance. Nickname: melt blown fabric, PP non-woven fabric English: Meltblowing Raw material: plastic Polypropylene (PP) melt blown fabric As a medical and health cloth, melt blown fabric is mainly used to manufacture medical protective clothing, surgical gowns, diapers, disinfection bags, sanitary napkins and other products Melt blown non-woven fabric inspection: 1. According to standard: FZ/T64034-2014 spunbonded/melt blown/spunbonded (SMS) method non-woven fabric. 2. Melt blown non-woven fabric inspection items: (1) Appearance quality inspection: fabric surface appearance, pores, impurities, odors, micropores, crystal points, melting blocks, rigid wires, unreinforced area, thin mesh, width deviation, color difference, and joint quality; (2) Internal quality testing: unit area quality deviation rate, longitudinal fracture strength, transverse fracture strength, longitudinal and transverse fracture elongation, hydrostatic pressure, and permeability; (3) Microbial indicators detection: total bacterial colony count, total fungal colony count, coliform group, pathogenic purulent bacteria
