A modifier made of a polyethylene glycol derivative is injected into the streams of branch paths 2 and 3 from modifier injection paths 5 and 5' through injection valves 4 and 4', and mixed with polyethylene terephthalate in mixers 6 and 6'.
After being metered by gear pumps 7 and 7' and further mixed by mixers 8 and 8', it is sent to spinning pack 10 through outflow passages 9 and 9', where modified polyethylene terephthalate filaments are spun. Injection valve 4 in figure 1
The same equipment is used to spin conventional polyethylene terephthalate filaments when 4' and 4' are closed and no modifier is injected. Also, in FIG. 1, the injection valve 4 is opened, and the injection valve 4' is closed to open the outflow passage 9.
When more modified polyethylene terephthalate and polyethylene terephthalate containing no modifier are sent to the spinning pack 10 from the outlet path 9',
A filament is spun out in which a phase of polyethylene terephthalate in which the modifier is not evenly mixed and a phase of polyethylene terephthalate in which no modifier is mixed are heterogeneously mixed. The spinning pack 11 for producing composite fibers shown in FIG. 2 is installed in place of the spinning pack 10 shown in FIG. A modifier is injected, mixed by mixers 6 and 8, and sent to the spinning pack 11 from the inflow path 9, and the polyethylene terephthalate from the branch path 3 is sent to the spinning pack from the outflow path 9' without injecting any modifier. 11, where they are joined in a parallel type or core-sheath type to spin out a composite filament.

-Mixer”, Sulzer’s “SM-Mixer”
etc., but other known mixers can of course also be used. The number of kneading elements varies depending on the type of polymer to be applied, the amount and type of modifier to be injected, or the degree of kneading. Too few kneading elements will result in insufficient kneading, while too many will cause pressure loss. However, generally at least 6, and usually 20 to 40, are used for each branch.

It is preferable to incorporate it into the wear plate of. By doing so, the pressure on the injection side of the modifier is not only kept constant over time and the metering accuracy of the modifier is stabilized, but also the mixer can be easily and compactly installed. In particular, when mixers are placed before and after the metering pump, not only does the kneading effect improve, but the pressure loss of the mixer 6 is borne by the previous pump, and the pressure loss of the mixer 8 is borne by the metering gear pump. As a result, it is possible to increase the overall allowable pressure loss, and stable spinning can be achieved.
