METHOD FOR MANUFACTURING A PLISSABLE TEXTILE FRAMEWORK WITH ELECTRICALLY LOADED FIBERS, AND A PLISSABLE TEXTILE FRAMEWORK

摘要

The present invention relates to a method for manufacturing a pleated textile structure having electrostatically charged fibers. At least two separate nozzle bars are used one is used respectively for the manufacture of thinner fibers and the other for the manufacture of coarser fibers by means of a melt spinning method. at least the first nozzle bar, which is used to make the coarser fibers, has concentric nozzles. the finer fibers and the coarser fibers are mixed in the process at least partially and, furthermore, are electrostatically charged by means of a polar liquid. With the textile structure filters with quality factors greater than 0.2 can be manufactured.
