Definitions

  • a plurality of filaments 10 are gathered together to form a yarn. Drawing and bulking of the combined filaments is performed by any method known in the art, with the preferred operating condition described below in the examples provided.
  • the carpet sample was placed in Vetterman drum. Two hundred grams (200 g) of clean nylon 101 Zytel nylon beads and fifty grams (50 g) of dirty beads (by DuPont Canada, Mississauga, Ontario) were placed on the sample.
  • the dirty beads were prepared by mixing ten grams (10 g) of AATCC TM-122 synthetic carpet soil (by Manufacturer Textile Innovators Corp. Windsor, N.C.) with one thousand grams (1000 g) of new Nylon 101 Zytel beads.
  • the filament had an exterior modification ratio of 1.88, a tip ratio of 3.5, an apex ratio of 1.33.
  • the central void occupied about ten percent (10%) of the cross sectional area of the filament.
