Definitions

  • a method for improving the distribution of binder and matrix filaments used in the preparation of nonwoven webs The binder and matrix filaments are spun from the same spinneret through orifices grouped to provide uniform distribution of the filaments, and then charged at two separate locations along their path of travel. The charge imparted at the first of such locations is at least 50 percent of the total charge applied to the filaments. The filaments are passed over a guide positioned between the two charging locations.
  • the guide has a concave surface contacting the filaments which prefera-bly has a radius of curvature in the range Qt from about 18 to ab ut 0 inches Feb. 10,1970. s. c. D'E B'BAS I T8719 SPINNING METHOD Filed May 20, 1969 FIG.2
