Abstract:
The present invention is directed to a draw jet for drawing thermoplastic polymer filaments comprising a drawing slot defined by an entrance member comprising a converging passageway communicating with a continuing passageway, terminating at an outlet portion, a drawing member comprising an inlet portion having a drawing gap width of about 2.0 to about 10 mm communicating with said outlet portion of said entrance member, and at least one air nozzle for directing high speed air onto said filaments in a downstream direction positioned between said outlet portion of said entrance member and said inlet portion of said drawing member, and with a nozzle gap width wherein the gap ratio of said drawing gap width to the combined width of all of said nozzle gaps is from about 1.0 to about 10.
