Beginning with the paper production, nonwoven has already a long history; and italso grows intensively in the last several decades owing to the new developed production techniques, such as melt-blown and electrospinning. Especially, the melt-blown and spunbond nonwoven fabrics/membranes fabrication is a fast process which can generate thin, light and strong nonwoven sheets by using various raw materials, including natural/bio fibers (cellulose, cotton etc.), synthetic polymers (polyester, polyolefin, polyamides etc.) and inorganic fibers (glass, metals and carbon fibers). The typical applications for nonwoven materials are filtration (air and liquid), textiles/medical uses (hygiene, masks, single-use surgical gowns), and others (geotextiles, packaging and absorbents). Herein, electronspinning and melt-blown manufactured nonwoven membranes for the application of lithium-ion battery (LIB), air filtration, and water cleaning are reported. Nylon-based nonwoven separators for LIB exhibited superior thermal stability with negligible thermal shrinkage, thus leading to an enhancement of the operation safety of LIBs. Via electric charging of PP-made nonwoven fabrics, the air filtration efficiency against 0.3 μm particles was more than 95%, which qualified these nonwoven fabrics as outstanding candidates for the masks and air-filtration medias to solve the problem of air pollution. The last but not the least, non-woven materials have been proven to be the most important materials for ultra-filtration and reverse osmosis filtration for the water cleaning. We believe that there is also a chance to combine graphene with non-woven membranes for more efficient water-cleaning system.
