Title: PROCESS AND APPARATUS FOR THE PRODUCTION OF NANOFIBERS
Abstract:
An apparatus for forming a non-woven mat of nanofibers by using a pressurized gas stream uncludes parallel, spaced apart first (12), second (22), and third (32) members, each having a supply end (14, 24, 34) and an opposing exit end (16, 26, 36). The second member (22) is adjacent to the first member (12). The exit end (26) of the second member (22) extends beyond the exit end (16) of the first member (12). The first (12) and second (22) members define a first supply slit (18). The third member (32) is located adjacent to the first member (12) on the opposite side of the first member (12) from the second member (22). The first (12) and third (32) members define a first gas slit (38), and the exit ends (16, 26, 36) of the first (12), second (22) and third (32) members define a gas jet space (20). A method for forming a nonwoven mat of nanofibers by using a pressurized gas stream is also included.
