Melt blown extrusion is a manufacturing process used to manufacture a non-woven fabric made of polymers such as polypropylene. Traditional fabrics made of natural materials such as cotton are woven together, which means that these materials first form yarns and then are intertwined through the weaving or weaving process, resulting in a layer of fabric from the yarn. Non woven fabrics do not involve connecting yarns by weaving or weaving; Instead, they mechanically, thermally or chemically bond materials made of separated fibers of molten polymers together to form a mesh fabric. The resulting fabric has many ideal properties, including absorption, bacterial barrier, cushioning, filtration, flame retardancy, liquid repellency, resilience, softness, stretch and washability
Non woven fabrics are used for many purposes, such as agriculture, automobiles, construction, personal hygiene, roofs, carpets, interior decoration and medical products. Specific examples of product types that can be manufactured using non-woven fibers include:
Filtration, such as HEPA air filters or liquid and gas filter products
Medical and industrial masks and respirators
Disposable medical clothing, such as robes, curtains, shoe covers and headgear
Sanitary products, such as female sanitary products and disposable diapers
Oil and liquid adsorbents, which contain spills and absorb oil from water
Coffee filter and tea bag
artificial grass
Insulation products
Meat and vegetable packaging tray
Disposable disinfection wipes
