摘要
In recent years,filtration nonwovens have been widely used in industrial filtration,protection,medical and other fields.The demand for nonwovens in the application field of filtration materials will increase by 2.7 percent annually by 2024,according to the latest forecast issued by the international industrial research organization Freedonia Group.The growth is mainly driven by four factors.The first is the continuous development of advanced nanofiber technology.Advanced nano-fiber technology makes nonwovens more competitive with alternative materials such as membranes.
