PLA熔喷非织造布兼有PLA的优点和熔喷工艺的优点，作为环境友好材料的PLA具有可再生、可生物降解、生物相容以及低碳排放和低能耗等特点。同时，PLA熔喷非织造布因为是用熔喷工艺，具有流程短、工艺简单、成本低的优点，这也正是PLA在熔喷工艺上应用的原因。

　　聚乳酸纳米熔喷布不仅具有聚乳酸熔喷材料生物可降解、环保的特点，同时结合了纳米纤维直径细、孔隙率高的优势，具备物理机械拦截、静电吸附两大功能，达到高效低阻，广泛应用于空气净化、防护口罩等领域。

　　Nanofiber meltblown fabrics use polylactic acid as the main raw material, It is 100% biodegradable, eco-friendly, good tensile strength, non-toxic, air- permeable, and the fiber diameter can reach 0.1 to 0.5 microns. These ultrafine fibers with unique capillary structures increase the number and surface area of fibers per unit area, small aperture, high efficiency and lower pressure drop, thereby making the nanofiber meltblown fabrics have good filterability, Shielding, heat insulation and oil absorption, can be used in the fields of air, liquid filtration materials, insulation materials, absorption materials, mask materials, thermal insulation materials and wiping cloths. After electret electrostatic treatment, it can enhance the ability to adsorb and filter bacteria and viruses. PLA nonwovens are able to pass the relevant EN13432, ISO 14855 and ASTM D6400, and ASTM D5338 biodegradability and biocompatibility measurements, while achieving industry leading.
