METHOD AND APPARATUS FOR PRODUCTION OF MELTBLOWN NANOFIBERS |
摘要 |
A method and apparatus for producing polymeric nanofibers utilizes a meltblown spinneret die having spin holes formed by grooves in plate(s) surface(s) of plate(s) where polymer exits at the plate(s) edge(s). The grooves are smaller than 0.005'' widex0.004'' deep and have an L/D at least as large as 20:1. Flow rates of polymer through the apparatus are very low, on the order of 0.01 ghm or less. The method/apparatus produces may also be viewed as including A meltblown fabric having fibers mostly less than 0.5 microns in diameter is produced. |
