The following information comes from the Internet for reference only

Melt-blown cloth has a finer fiber structure, so it has a better ability to capture particles. The raw material of meltblown cloth has good processing performance and good chemical resistance ability, so the porosity is large, the specific surface area is large, and the filtering effect is good. Medical and sanitary cloths are mainly used for medical protective clothing, medical masks, diapers, disinfection bags and other products. In industry, it can also be used to produce insulating materials and filter materials. The following micro-spectrum introduces the knowledge about the inspection of meltblown cloth materials.
1. Meltblown cloth raw material inspection report:
Hot melt cloth raw material inspection report:
1. Appearance quality inspection: micropores, crystal points, frit, hard wire, unreinforced area, surface appearance, perforation impurities, odor, thin net, width deviation, color difference, and joint quality.
2. Internal quality inspection: transverse breaking strength, longitudinal elongation at break, mass deviation per unit area, longitudinal breaking strength, hydrostatic pressure, and air permeability. 3. Inspection of sanitary indicators: total number of bacterial colonies, coliforms, total number of fungal colonies, and pathogenic pyogenic bacteria.
4. Other tests: bacterial filtration efficiency test. Particle filtration efficiency test. Ventilation resistance and pressure difference test. Air resistance and breathing resistance test.
5. Technical requirements for testing items: particle appearance, volatile matter mass flow rate, ash content, and tert-butyl peroxide. Molecular weight distribution.
2. Inspection standard of melt blown cloth raw materials:
