Abstract
A process is described for the production of high
strength polyester yarn wherein the conventional spin draw
process has been modified. Yarn having a tenacity of at least
7.5 g/d and an elongation of at least 9% may be spun using
this process at a speed of at least 1900 meters per minute.
The yarn may be used in tire cord and other industrial
applications.
Figures 1 and 2 illustrate in schematic form the general
process steps of spinning and drawing respectively. Polyes
ter in the form of melt extrudable polyethylene terephthalate
(PET) is charged to a hopper 12 which empties into a screw
extruder 14 which thereupon mixes and heats the polyester
to a temperature of about 287°C.
The now molten polyester is pressure fed by the
extruder to a spinnarette 16 having a plurality of capillaries
17 through which the polyester is extruded. The number of
capillaries can vary from about 50 to over 100. The extruded
filaments are maintained at a temperature near the melting
point of PET by a quench delay collar 20 often referred to
simply as a quench collar. The filaments are then quenched
by an inert gas or air stream 22 of ambient temperature
before passing though a chute 24. The filaments 18 are now
in a solid state.
At the end of the chute 24 is a tray and kiss roll 26 which
applies a conventional spin finish compound to the fila
ments. The filaments are then converged at point 28 into
yarn 30, which is thereafter transported by a pretension
godet 32, godets 34 and guide rolls 36 to winder 38, where
the yarn is wound and may be either stored for future
drawing or may be used as feed immediately to the drawing
process in continuous fashion.
The drawing process is illustrated in Figure 2. Yarn 30
from winder 38 passes between pretention rolls 42 and over
guide roll 44 to top godet 46. The yarn then travels around
draw pin 50 which localizes the draw at a point just below top
godet 46. The amount of draw is governed by the relative
rotational speeds of top godet 46 and a bottom godet 56, the
latter rotating at a high speed than top godet 46.
After passing over draw pin 50, the yarn 30 passes over a
platen 52 before being wound on the bottom godet 56. Rolls
48 and 58 separate the wraps and keep them from rubbing
against each other. Platen 52 is heated to a temperature of
about 215°C. to about 230°C. From the bottom godet, the now
drawn yarn passes through guide loops 60 and is wound
onto a spool 62. The yarn is now ready for use at this point.
